106-494: The Network periodically submits reports to UNESCO on current land-management issues related to the region's biodiversity and its connection to people. Recent efforts have focused on outreach to potential collaborators and promoting research on biodiversity and climate change adaptation . The Golden Gate Biosphere network is a coalition with the goal of conserving the environment of the San Francisco Bay Area. It

212-432: A climate response rather: The IPCC Sixth Assessment Report states: "Some responses, such as migration, relocation and resettlement may or may not be considered to be adaptation". Habitat In ecology , habitat refers to the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species . A species habitat can be seen as

318-400: A free content work ( license statement/permission ). Text taken from UNESCO - MAB Biosphere Reserves Directory​ , UNESCO, UNESCO. Climate change adaptation Climate change adaptation is the process of adjusting to the effects of climate change . These can be both current or expected impacts. Adaptation aims to moderate or avoid harm for people, and

424-423: A parasitic organism has as its habitat the body of its host , part of the host's body (such as the digestive tract), or a single cell within the host's body. Habitat types are environmental categorizations of different environments based on the characteristics of a given geographical area, particularly vegetation and climate. Thus habitat types do not refer to a single species but to multiple species living in

530-647: A conduit for the dispersal of pollen grains, spores and seeds , the atmosphere can be considered to be a habitat-type in its own right. There are metabolically active microbes present that actively reproduce and spend their whole existence airborne, with hundreds of thousands of individual organisms estimated to be present in a cubic meter of air. The airborne microbial community may be as diverse as that found in soil or other terrestrial environments, however, these organisms are not evenly distributed, their densities varying spatially with altitude and environmental conditions. Aerobiology has not been studied much, but there

636-433: A disaster: it's only when it affects people or is caused by them that is counts as a disaster. It is argued that natural disasters are always linked to human action or inaction or rooted in anthropogenic processes . Disasters, economic loss, and the underlying vulnerabilities that drive risk are increasing. Global risks like climate change are having major impacts everywhere. Scientists forecast climate change will increase

742-489: A downpour occurs and lays its eggs in the transient pools that form; the tadpoles develop with great rapidity, sometimes in as little as nine days, undergo metamorphosis , and feed voraciously before digging a burrow of their own. Other organisms cope with the drying up of their aqueous habitat in other ways. Vernal pools are ephemeral ponds that form in the rainy season and dry up afterwards. They have their specially-adapted characteristic flora, mainly consisting of annuals,

848-413: A forest is divided into parts by logging, with strips of cleared land separating woodland blocks, and the distances between the remaining fragments exceeds the distance an individual animal is able to travel, that species becomes especially vulnerable. Small populations generally lack genetic diversity and may be threatened by increased predation, increased competition, disease and unexpected catastrophe. At

954-896: A higher share of plant-based foods . This has both mitigation and adaptation benefits. Plant-based options have much lower energy and water requirements. Adaptation options can investigate the dietary patterns that are better suited to the regional, socioeconomic and cultural context. Social-cultural norms strongly affect preferences for foods. Policies such as subsidies, taxes, and marketing can also support dietary choices that help adaptation. Agriculture offers many opportunities for adaptation. These include changing planting times, or changing to crops and livestock that are better adapted to climate conditions and presence of pests. Other examples are breeding more resilient crops and selecting genetically modified crops. All these aim to improve food security and nutrition. Migration counts as behavioural climate adaptation for some, although others refer to it as

1060-526: A home for both static organisms, anchored to the substrate , and for a large range of organisms crawling on or burrowing into the surface. Some creatures float among the waves on the surface of the water, or raft on floating debris, others swim at a range of depths, including organisms in the demersal zone close to the seabed, and myriads of organisms drift with the currents and form the plankton . Many animals and plants have taken up residence in urban environments. They tend to be adaptable generalists and use

1166-564: A knowledge loop that includes targeted user communities' access to, interpretation of, communication of, and use of pertinent, accurate, and trustworthy climate information, as well as their feedback on that use. Climate information services involve the timely production, translation and delivery of useful climate data, information and knowledge. Institutional responses include zoning regulations, new building codes , new insurance schemes, and coordination mechanisms. Policies are important tools to integrate issues of climate change adaptation. At

1272-716: A mile below the ice of Antarctica; in the absence of sunlight, they must rely on organic material from elsewhere, perhaps decaying matter from glacier melt water or minerals from the underlying rock. Other bacteria can be found in abundance in the Mariana Trench , the deepest place in the ocean and on Earth; marine snow drifts down from the surface layers of the sea and accumulates in this undersea valley, providing nourishment for an extensive community of bacteria. Other microbes live in environments lacking in oxygen, and are dependent on chemical reactions other than photosynthesis . Boreholes drilled 300 m (1,000 ft) into

1378-444: A natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or are dead, leading to a decrease in biodiversity and species numbers . Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. The protection of habitat types is a necessary step in the maintenance of biodiversity because if habitat destruction occurs,

1484-410: A parasitic organism, its habitat is the particular part of the outside or inside of its host on or in which it is adapted to live. The life cycle of some parasites involves several different host species, as well as free-living life stages, sometimes within vastly different microhabitat types. One such organism is the trematode (flatworm) Microphallus turgidus , present in brackish water marshes in

1590-557: A particular species well, but its presence or absence at any particular location depends to some extent on chance, on its dispersal abilities and its efficiency as a colonizer. Arid habitats are those where there is little available water. The most extreme arid habitats are deserts . Desert animals have a variety of adaptations to survive the dry conditions. Some frogs live in deserts, creating moist habitat types underground and hibernating while conditions are adverse. Couch's spadefoot toad ( Scaphiopus couchii ) emerges from its burrow when

1696-487: A similar way; their eggs hatch and the juvenile fish grow with great rapidity when the conditions are right, but the whole population of fish may end up as eggs in diapause in the dried up mud that was once a pond. Freshwater habitat types include rivers, streams, lakes, ponds, marshes and bogs. They can be divided into running waters (rivers, streams) and standing waters (lakes, ponds, marshes, bogs). Although some organisms are found across most of these habitat types,

1802-509: A similarly rich fauna of invertebrates as a more varied habitat. The monotypic habitat occurs in both botanical and zoological contexts. Some invasive species may create monocultural stands that prevent other species from growing there. A dominant colonization can occur from retardant chemicals exuded, nutrient monopolization, or from lack of natural controls, such as herbivores or climate, that keep them in balance with their native habitat types. The yellow starthistle, Centaurea solstitialis

1908-498: A variety of bacteria and fungi; and snowfields on which algae grow. Whether from natural processes or the activities of man, landscapes and their associated habitat types change over time. There are the slow geomorphological changes associated with the geologic processes that cause tectonic uplift and subsidence , and the more rapid changes associated with earthquakes, landslides, storms, flooding, wildfires, coastal erosion , deforestation and changes in land use. Then there are

2014-441: A violent event (such as the eruption of a volcano , an earthquake , a tsunami , a wildfire or a change in oceanic currents); or change may occur more gradually over millennia with alterations in the climate , as ice sheets and glaciers advance and retreat, and as different weather patterns bring changes of precipitation and solar radiation . Other changes come as a direct result of human activities, such as deforestation ,

2120-423: A wide range of Brassicas and various other plant species, and it thrives in any open location with diverse plant associations. The large blue butterfly Phengaris arion is much more specific in its requirements; it is found only in chalk grassland areas, its larvae feed on Thymus species, and because of complex life cycle requirements it inhabits only areas in which Myrmica ants live. Disturbance

2226-509: A year for the coming decades. In many cases, the cost will be less than the damage that it avoids. The IPCC defines climate change adaptation in this way: Adaptation actions can be incremental and transformative. Incremental actions are actions that aim to maintain the essence and integrity of a system. Transformative actions are actions that change the fundamental attributes of a system in response to climate change and its impacts. Research on climate change adaptation has been ongoing since

2332-562: Is chemosynthesis , a process by which microbes convert such substances as hydrogen sulfide or ammonia into organic molecules. These bacteria and Archaea are the primary producers in these ecosystems and support a diverse array of life. About 350 species of organism, dominated by molluscs , polychaete worms and crustaceans , had been discovered around hydrothermal vents by the end of the twentieth century, most of them being new to science and endemic to these habitat types. Besides providing locomotion opportunities for winged animals and

2438-430: Is a closely related area of work and research topic that has recently emerged. It describes situations in which adaptation, mitigation and development solutions are pursued together. It is able to benefit from synergies from among the actions and reduce trade-offs. Strategies to limit climate change are complementary to efforts to adapt to it. Limiting warming, by reducing greenhouse gas emissions and removing them from

2544-404: Is a concept sometimes used in conservation biology , in which a single species of animal or plant is the only species of its type to be found in a specific habitat and forms a monoculture . Even though it might seem such a habitat type is impoverished in biodiversity as compared with polytypic habitat types, this is not necessarily the case. Monocultures of the exotic plant Hydrilla support

2650-516: Is a vigorous grass from Europe which has been introduced to the United States where it has become invasive. It is highly adapted to fire, producing large amounts of flammable detritus and increasing the frequency and intensity of wildfires. In areas where it has become established, it has altered the local fire regimen to such an extant that native plants cannot survive the frequent fires, allowing it to become even more dominant. A marine example

2756-705: Is also rich with cougars , Tule elk , California sea lions , elephant seals , and many shorebirds. Under the Endangered Species Act of 1973 , the Bay Area is home to over 90 endangered or threatened animal and plant species. Endangered land animals found here include the California red-legged frog , Alameda whipsnake , California tiger salamander . Endangered fish include Central California Coast steelhead trout , coho salmon , and southern green sturgeon . Endangered birds and butterflies include

2862-421: Is an important step in understanding current and future adaptation needs and options. As of 2022, the level of warming is 1.2 °C (34.2 °F) above levels before the industrial revolution. It is on track to increase to 2.5 to 2.9 °C (36.5 to 37.2 °F) by the end of the century. This is causing a variety of secondary effects. Many negative effects of climate change involve changes in extremes or

2968-547: Is because evacuation and emergency access becomes easier. Reduced air pollution from public transport improves health. This in turn may lead to improved economic resilience, as healthy workers perform better. There are many adaptation responses. We sometimes call them adaptation measures, strategies or solutions. They help manage impacts and risks to people and nature. Current adaptation focuses on near-term climate risks. It also focuses on particular sectors, such as water and agriculture, and on regions, such as Africa and Asia. It

3074-638: Is because transformational adaptation is connected with implementation at scale and ideally at the system-level. Strengthening resilience is therefore important for maintaining a capacity for transformation. Transformations, and the processes of transition, cover the major systems and sectors at scale. These are energy, land and ecosystems, urban and infrastructure, and industrial and societal. Transformations may fail if they do not integrate social justice, consider power differences and political inclusion, and if they do not deliver improvements in incomes and wellbeing for everyone. Climate resilient development

3180-494: Is evidence of nitrogen fixation in clouds , and less clear evidence of carbon cycling, both facilitated by microbial activity. There are other examples of extreme habitat types where specially adapted lifeforms exist; tar pits teeming with microbial life; naturally occurring crude oil pools inhabited by the larvae of the petroleum fly ; hot springs where the temperature may be as high as 71 °C (160 °F) and cyanobacteria create microbial mats ; cold seeps where

3286-559: Is important in the creation of biodiverse habitat types. In the absence of disturbance, a climax vegetation cover develops that prevents the establishment of other species. Wildflower meadows are sometimes created by conservationists but most of the flowering plants used are either annuals or biennials and disappear after a few years in the absence of patches of bare ground on which their seedlings can grow. Lightning strikes and toppled trees in tropical forests allow species richness to be maintained as pioneering species move in to fill

3392-468: Is important to close gaps between adaptation that is carried out and the needs relative to today's climate in order to reduce risks to a tolerable level. However, future adaptation must also anticipate future climate change risks. Some options may become less effective or entirely unfeasible as global warming increases. Adaptation responses fall into four categories that all directly aim to reduce risks and exploit opportunities: We can also group options

3498-490: Is important to help countries manage climate risks. Plans, policies or strategies are in place in more than 70% of countries. Agreements like the Paris Agreement encourage countries to develop adaptation plans. Other levels of government like cities and provinces also use adaptation planning. So do economic sectors. Donor countries can give money to developing countries to help develop national adaptation plans. This

3604-458: Is important to help them implement more adaptation. Monitoring and evaluation activities are key parts of adaptation efforts. They ensure strategies work well and allow for necessary changes along the way. The adaptation carried out so far is not enough to manage risks at current levels of climate change. And adaptation must also anticipate future risks of climate change. The costs of climate change adaptation are likely to cost billions of dollars

3710-799: Is in three categories: 1. Structural and physical adaptation (including engineering and built environment, technological, ecosystem-based, services); 2. Social adaptation (educational, informational, behavioural); 3. Institutional adaptation (economic organizations, laws and regulation, government policies and programmes). Other ways to distinguish types of adaptation are anticipatory versus reactive, autonomous versus planned and incremental versus transformational. Built environment options include installing or upgrading infrastructure to protect against flooding, sea level rise, heatwaves and extreme heat. They also include infrastructure to respond to changed rainfall patterns in agriculture. This could be infrastructure for irrigation. These are explained further in

3816-718: Is marine habitat. This marine area covers 26,319 square miles (6,817,000 ha) whilst the terrestrial area covers 1,694 square miles (439,000 ha). The Region extends through the North-Central California coastal region from the Bodega Marine Reserve in the north to Jasper Ridge in the south and includes the Farallon Islands , Angel Island , and includes Alcatraz within the San Francisco Bay . The biosphere region

3922-443: Is not possible to directly reduce hazards. This is because hazards are affected by current and future changes in climate. Instead, adaptation addresses the risks of climate impacts that arise from the way climate-related hazards interact with the exposure and vulnerability of human and ecological systems. Exposure refers to the presence of people, livelihoods, ecosystems and other assets in places that could suffer negative effects. It

4028-470: Is one way to reduce vulnerability to climate hazards. For instance, mangroves can dampen storm energy. So they can help prevent flooding. In this way, protection of the mangrove ecosystem can be a form of adaptation. Insurance and livelihood diversification increase resilience and decrease vulnerability. Other ways to decrease vulnerability include strengthening social protection and building infrastructure more resistant to hazards. Adaptive capacity in

4134-412: Is part of the broader consideration of sustainable development . Climate change adaptation and disaster risk reduction have similar goals (to reduce potential impacts of hazards and increase the resilience of people at risk). They use similar concepts and are informed by similar sources and studies. Disasters are often triggered by natural hazards. A natural event such as a fire or flood is not of itself

4240-447: Is possible to reduce exposure by retreating from areas with high climate risks, such as floodplains. Improving systems for early warnings and evacuations are other ways to reduce exposure. The IPCC defines climate change vulnerability as "the propensity or predisposition to be adversely affected" by climate change. It can apply to humans but also to natural systems . Human and ecosystem vulnerability are interdependent. According to

Core areas, otherwise known as protected area, are legally constituted core areas devoted to long-term protection. The core areas of the Golden Gate Biosphere region are of sufficient size to serve the three functions required of biosphere regions mentioned previously. Marine protected areas within

4452-504: Is strong variation within countries. The determinants of adaptive capacity include: The IPCC considers climate resilience to be “the capacity of social, economic and ecosystems to cope with a hazardous event or trend or disturbance”. It includes the abilities to reorganise and learn. This definition is similar to that of climate change adaptation. However, resilience involves a more systematic approach to absorbing change. It involves using those changes to become more efficient. The idea

4558-423: Is that people can intervene to reorganise the system when disturbance creates an opportunity to do so. Implemented adaptation most often builds upon resilience as a way of bouncing back to recover after a disturbance. Experts consider it to be incremental rather than transformational. On the other hand, climate resilience-focused projects can be activities to promote and support transformational adaptation. This

4664-416: Is the small-scale physical requirements of a particular organism or population. Every habitat includes large numbers of microhabitat types with subtly different exposure to light, humidity, temperature, air movement, and other factors. The lichens that grow on the north face of a boulder are different from those that grow on the south face, from those on the level top, and those that grow on the ground nearby;

4770-1252: Is usually done alongside climate change mitigation . It also aims to exploit opportunities. Humans may also intervene to help adjust for natural systems. There are many adaptation strategies or options. For instance, building hospitals that can withstand natural disasters, roads that don't get washed away in the face of rains and floods. They can help manage impacts and risks to people and nature. The four types of adaptation actions are infrastructural , institutional, behavioural and nature-based options. Some examples of these are building seawalls or inland flood defenses, providing new insurance schemes, changing crop planting times or varieties, and installing green roofs or green spaces. Adaptation can be reactive (responding to climate impacts as they happen) or proactive (taking steps in anticipation of future climate change). The need for adaptation varies from place to place. Different regions must adapt differently because they each face particular sets of climate risks . For instance, coastal regions might prioritize sea-level rise defenses and mangrove restoration. Arid areas could focus on water scarcity solutions, land restoration and heat management. The needs for adaptation will also depend on how much

4876-507: Is very challenging to research, and as well as being little-studied, it is vast, with 79% of the Earth's biosphere being at depths greater than 1,000 m (3,300 ft). With no plant life, the animals in this zone are either detritivores , reliant on food drifting down from surface layers, or they are predators, feeding on each other. Some organisms are pelagic , swimming or drifting in mid-ocean, while others are benthic, living on or near

4982-468: Is when sea urchin populations " explode " in coastal waters and destroy all the macroalgae present. What was previously a kelp forest becomes an urchin barren that may last for years and this can have a profound effect on the food chain . Removal of the sea urchins, by disease for example, can result in the seaweed returning, with an over-abundance of fast-growing kelp. Habitat destruction (also termed habitat loss and habitat reduction) occurs when

5088-554: The Latin habitāre , to inhabit, from habēre , to have or to hold. Habitat can be defined as the natural environment of an organism , the type of place in which it is natural for it to live and grow. It is similar in meaning to a biotope ; an area of uniform environmental conditions associated with a particular community of plants and animals. The chief environmental factors affecting the distribution of living organisms are temperature, humidity, climate, soil and light intensity , and

5194-567: The Western snowy plover , Brown pelican , Mission blue butterfly , and Bay checkerspot butterfly . Endangered plants include the Contra Costa goldfields , Suisun thistle , yellow larkspur , San Francisco Wallflower , and Clarkia franciscana . The Golden Gate Biosphere region is unique for having marine, coastal, and upland resources adjacent to a major metropolitan area, thus providing easy access to outdoor education and recreation for

5300-628: The codes or regulations that buildings must conform to is important for keeping people healthy and comfortable during extremes of hot and cold and protecting them from floods. There are many ways to do this. They include increasing the insulation values, adding solar shading, increasing natural ventilation or passive cooling , codes for green roofs to reduce urban heat island effects or requiring waterfront properties to have higher foundations. Land use zoning controls are central to investment in urban development . They can reduce risks to areas threatened by floods and landslides. Insurance spreads

5512-467: The photic zone in the oceans are relatively familiar habitat types. However the vast bulk of the ocean is inhospitable to air-breathing humans, with scuba divers limited to the upper 50 m (160 ft) or so. The lower limit for photosynthesis is 100 to 200 m (330 to 660 ft) and below that depth the prevailing conditions include total darkness, high pressure, little oxygen (in some places), scarce food resources and extreme cold. This habitat

5618-454: The plowing of ancient grasslands, the diversion and damming of rivers, the draining of marshland and the dredging of the seabed. The introduction of alien species can have a devastating effect on native wildlife – through increased predation , through competition for resources or through the introduction of pests and diseases to which the indigenous species have no immunity. The word "habitat" has been in use since about 1755 and derives from

5724-747: The 1990s. The number and variety of subtopics has greatly increased since then. Adaptation has become an established policy area in the 2010s and since the Paris Agreement, and an important topic for policy research. Scientific research into climate change adaptation generally starts with analyses of the likely effects of climate change on people, ecosystems, and the environment. These impacts cover its effects on lives, livelihoods, health and well-being, ecosystems and species, economic, social and cultural assets, and infrastructure. Impacts may include changed agricultural yields, increased floods, and droughts or coral reef bleaching. Analysis of such impacts

5830-852: The GGB region are limited to beef and dairy ranching within Point Reyes National Seashore and the northern district of Golden Gate National Recreation Area . Approximately 28,000 acres of land are permitted for ranching. The National Park Service and ranchers collaborate on issues of importance to maintaining biodiversity within the biosphere, including water quality, archaeological site preservation, ranch diversification, weed management, historic structure and landscape maintenance, sustainable agricultural practices, and habitat restoration. The GGBN works collaboratively on projects related to stewardship, science, and education. Partners cooperate on tidal pool monitoring and public education in

5936-619: The Global Goal are in development as of 2023. It will support the long-term adaptation goals of the governments that are parties to the agreement. It also aims to fund support for the most vulnerable countries’ adaptation needs in the context of the 1.5/2 °C goal. It has three core components. These are reducing vulnerability to climate change, enhancing adaptive capacity, and strengthening resilience. Adaptation can help decrease climate risk by addressing three interacting risk factors. These are hazards , vulnerability , and exposure. It

6042-579: The Golden Gate Biosphere includes marine, aquatic ecosystems and terrestrial ecosystems such as evergreen forests (including the endemic Coast Redwood ), oak woodlands, chaparral, coastal scrub and prairies, rare serpentine grasslands, as well as coastal and offshore islands. It also contains four Ramsar Wetlands of international importance: the Laguna de Santa Rosa Wetland Complex , Tomales Bay , Bolinas Lagoon , and San Francisco Bay Estuary. These habitats are threatened by human activities and settlement within

6148-606: The IPCC, climate change vulnerability encompasses a variety of concepts and elements, including sensitivity or susceptibility to harm and lack of capacity to cope and adapt. Sensitivity to climate change could be reduced by for example increasing the storage capacity of a reservoir, or planting crops that are more resistant to climate variability. It is also possible to reduce vulnerability in towns and cities with green garden spaces. These can reduce heat stress and food insecurity for low-income neighbourhoods. Ecosystem-based adaptation

6254-497: The UN is running a partnership titled "Climate Risk and Early Warning Systems" to aid high risk countries with neglected warning systems in developing them. Climate Information Services (CIS) (or climate services) entail the dissemination of climate data in a way that aids people and organizations in making decisions. CIS helps its users foresee and control the hazards associated with a changing and unpredictable climate. It encompasses

6360-578: The ability to design and implement effective adaptation strategies, or to react to evolving hazards and stresses. Societies that can respond to change quickly and successfully have a high adaptive capacity. Conversely, high adaptive capacity does not necessarily lead to successful adaptation action. It does not necessarily succeed in goals of equity and enhancing well-being. In general, adaptation capacity differs between high and low-income countries. By some indices such as ND-GAIN , high-income countries tend to have higher adaptive capacity. However, there

6572-436: The animals and plants reliant on that habitat suffer. Many countries have enacted legislation to protect their wildlife. This may take the form of the setting up of national parks, forest reserves and wildlife reserves, or it may restrict the activities of humans with the objective of benefiting wildlife. The laws may be designed to protect a particular species or group of species, or the legislation may prohibit such activities as

6678-642: The area of Mount Tamalpais State Park . Another joint activity is the Coho salmon restoration project, which requires habitat inventorying and mapping of several critical watersheds . Within the last decade, collaborative projects within the 1,492 acres of the Presidio site involved the removal of six landfills. Those locations were subsequently restored with native habitats including one creek, three dune systems, one riparian system, two serpentine sites, and one Colma site, leading to increased habitats and populations of

6784-400: The atmosphere, is also known as climate change mitigation . There are some synergies or co-benefits between adaptation and mitigation. Synergies include the benefits of public transport for both mitigation and adaptation. Public transport has lower greenhouse gas emissions per kilometer travelled than cars. A good public transport network also increases resilience in case of disasters. This

6890-646: The biosphere include the following conservation units: Terrestrial protected areas include the following conservation units: In addition to these protected areas, the Golden Gate Biosphere region includes buffer zones and transition areas. Buffer zones, also known as managed use areas, are clearly identified and surrounding or contiguous to the core area or areas, where only activities compatible with conservation objectives and sound ecological practices can take place. These areas help reinforce scientific research, monitoring, training, and education. Transition areas, or areas of partnership and cooperation, are outer areas where

6996-416: The changes in habitat types brought on by alterations in farming practices, tourism, pollution, fragmentation and climate change. Loss of habitat is the single greatest threat to any species. If an island on which an endemic organism lives becomes uninhabitable for some reason, the species will become extinct . Any type of habitat surrounded by a different habitat is in a similar situation to an island. If

7102-500: The climate changes or is expected to change, which is different from place to place. Adaptation is particularly important in developing countries because they are most vulnerable to climate change. Adaptation needs are high for food, water and other sectors important for economic output, jobs and incomes. One of the challenges is to prioritize the needs of communities, including the poorest, to help ensure they are not disproportionately affected by climate change. Adaptation planning

7208-455: The collecting of bird eggs, the hunting of animals or the removal of plants. A general law on the protection of habitat types may be more difficult to implement than a site specific requirement. A concept introduced in the United States in 1973 involves protecting the critical habitat of endangered species , and a similar concept has been incorporated into some Australian legislation. International treaties may be necessary for such objectives as

7314-433: The context of climate change covers human, natural, or managed systems. It looks at how they respond to both climate variability and extremes. It covers the ability of a system to adjust to climate change to moderate potential damages, to take advantage of opportunities, or to cope with consequences. Adaptive capacity is the ability to reduce the likelihood of negative impacts of climate-related hazards. It does this through

7420-420: The edge of each forest fragment, increased light encourages secondary growth of fast-growing species and old growth trees are more vulnerable to logging as access is improved. The birds that nest in their crevices, the epiphytes that hang from their branches and the invertebrates in the leaf litter are all adversely affected and biodiversity is reduced. Habitat fragmentation can be ameliorated to some extent by

7526-602: The endangered species San Francisco Lessingia and Franciscan Clarkia . The Network also cooperates with the Iroise Biosphere Reserve of France in a comparison of coastal ecosystem recovery after human use changes. Research covers topics such as: the management of commercially important resources such as fisheries; threats to ecosystems such as oil spills , pollutants, and invasive species ; and episodic events such as wildfires and climate extremes.

For example, index-based insurance is a new product which triggers payment when weather indices such as precipitation or temperature cross a threshold. It aims to help customers such as farmers deal with production risks. Access to reinsurance may make cities more resilient. Where there are failures in

7738-624: The food supply chain. Thus it can be a risk to food security and nutrition. Adaptation measures can review the production, processing and other handling practices of suppliers. Examples include further sorting to separate damaged products, drying the product for better storage or improved packaging. Other behaviour change options for retailers and consumers include accepting fruit and vegetables that appear less than perfect, redistributing food surpluses, and lowering prices on nearly expired food. Dietary change options in regions with excess consumption of calories include replacing meat and dairy foods with

7844-506: The frequency and severity of extreme weather events and disasters. So adaptation may include measures to increase preparedness and relevant disaster response capacities. For humans, adaptation aims to moderate or avoid harm, and to exploit opportunities. For natural systems, humans may intervene to help adjustment. The Paris Agreement of 2015 requires countries to keep global temperature rise this century to less than 2 °C above pre-industrial levels, and to pursue efforts to limit

7950-745: The gaps created. Similarly, coastal habitat types can become dominated by kelp until the seabed is disturbed by a storm and the algae swept away, or shifting sediment exposes new areas for colonisation. Another cause of disturbance is when an area may be overwhelmed by an invasive introduced species which is not kept under control by natural enemies in its new habitat. Terrestrial habitat types include forests, grasslands, wetlands and deserts. Within these broad biomes are more specific habitat types with varying climate types, temperature regimes, soils, altitudes and vegetation. Many of these habitat types grade into each other and each one has its own typical communities of plants and animals. A habitat-type may suit

8056-508: The global south. Behavioural adaptation is a change in the strategies, practices and actions that help to reduce risk. These can include protecting homes from flooding, protecting crops from drought, and adopting different income-earning activities. Behavioural change is the most common form of adaptation. Food waste spoilage increases with exposure to higher temperatures and humidity. It also increases with extreme events such as flooding and contamination. This can happen at different points in

8162-402: The greatest activity is allowed. Sustainable resource management practices are promoted and developed in these areas in an effort to foster sociologically, culturally and ecologically sustainable economic and human development. The biosphere is considered a biodiversity hotspot , as human habitation threatens its high biodiversity. With over 3000 terrestrial and marine plant and animal species,

8268-499: The inhabitants of the San Francisco Bay metropolitan area . The Biosphere region provides important economic opportunities to the San Francisco Bay Area and annually receives 26.5 million visitors. Many recreational activities such as sport fishing, hiking, bicycling, whale watching, sightseeing, backpacking, picnicking, kayaking, surfing, boating, swimming, scuba-diving, snorkeling, cultural activities, museums, dining, and overnight lodging are available. Agricultural activities within

8374-720: The lichens growing in the grooves and on the raised surfaces are different from those growing on the veins of quartz. Lurking among these miniature "forests" are the microfauna , species of invertebrate , each with its own specific habitat requirements. There are numerous different microhabitat types in a wood; coniferous forest, broad-leafed forest, open woodland, scattered trees, woodland verges, clearings, and glades; tree trunk, branch, twig, bud, leaf, flower, and fruit; rough bark, smooth bark, damaged bark, rotten wood, hollow, groove, and hole; canopy, shrub layer, plant layer, leaf litter , and soil; buttress root, stump, fallen log, stem base, grass tussock, fungus, fern, and moss. The greater

8480-531: The majority have more specific requirements. The water velocity, its temperature and oxygen saturation are important factors, but in river systems, there are fast and slow sections, pools, bayous and backwaters which provide a range of habitat types. Similarly, aquatic plants can be floating, semi-submerged, submerged or grow in permanently or temporarily saturated soils besides bodies of water. Marginal plants provide important habitat for both invertebrates and vertebrates, and submerged plants provide oxygenation of

8586-805: The national level, adaptation strategies appear in National Adaptation Plans (NAPS) and National Adaptation Programmes of Action ( NAPA ). They also occur in national climate change policies and strategies. These are at different levels of development in different countries and in cities. This is discussed further in the section below on "implementation". Cities, states, and provinces often have considerable responsibility in land use planning, public health, and disaster management. Institutional adaptation actions occur more frequently in cities than in other sectors. Some have begun to adapt to threats intensified by climate change, such as flooding, bushfires, heatwaves, and rising sea levels. Managing

8692-521: The needs of the local residents for food, fuel and other resources. Faced with hunger and destitution, a farmer is likely to plough up a level patch of ground despite it being the last suitable habitat for an endangered species such as the San Quintin kangaroo rat , and even kill the animal as a pest. In the interests of ecotourism it is desirable that local communities are educated on the uniqueness of their flora and fauna. A monotypic habitat type

8798-412: The physical manifestation of its ecological niche . Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil , moisture , range of temperature , and light intensity . Biotic factors include the availability of food and

8904-414: The presence or absence of predators . Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior of a stem, a rotten log, a rock or a clump of moss ;

9010-419: The presence or absence of all the requirements that the organism needs to sustain it. Generally speaking, animal communities are reliant on specific types of plant communities. Some plants and animals have habitat requirements which are met in a wide range of locations. The small white butterfly Pieris rapae for example is found on all the continents of the world apart from Antarctica . Its larvae feed on

9116-648: The private insurance market, the public sector can subsidize premiums. One study identified key equity issues for policy considerations: Government-subsidized insurance, such as the U.S. National Flood Insurance Program, comes under criticism for providing a perverse incentive to develop properties in hazardous areas. This increases overall risk. Insurance can also undermine other efforts such as property level protection and resilience to increase adaptation. Appropriate land-use policies can counter this behavioural effect. These policies limit new construction where there are current or future climate risks. They also encourage

9222-545: The proteins the flexibility they need. There are also unsaturated fats in their membranes which prevent them from solidifying at low temperatures. Hydrothermal vents were first discovered in the ocean depths in 1977. They result from seawater becoming heated after seeping through cracks to places where hot magma is close to the seabed. The under-water hot springs may gush forth at temperatures of over 340 °C (640 °F) and support unique communities of organisms in their immediate vicinity. The basis for this teeming life

9328-428: The provision of wildlife corridors connecting the fragments. These can be a river, ditch, strip of trees, hedgerow or even an underpass to a highway. Without the corridors, seeds cannot disperse and animals, especially small ones, cannot travel through the hostile territory, putting populations at greater risk of local extinction . Habitat disturbance can have long-lasting effects on the environment. Bromus tectorum

9434-490: The region. A diverse range of marine, coastal, and upland habitats of the California chaparral and woodlands and Northern California coastal forests ecoregions may be found, including mixed evergreen forests , Coast Redwood forests, Douglas-fir forests, Bishop pine forests, oak forests, woodlands and savannas, northern coastal scrub , chaparral , coastal dune , coastal strand , tidepools , kelp forests , coastal grasslands , and marshes. The associated fauna

9540-430: The regional scale. Biosphere regions serve three functions: to foster relationships between humans and nature that allow for sustainable development , to contribute to the conservation of landscapes, ecosystems, and species of flora and fauna, and to provide support for research, monitoring, and education within the region. The Golden Gate Biosphere region consists of 27,976 square miles (7,246,000 ha) of which 94%

9646-573: The rocky seabed have found microbial communities apparently based on the products of reactions between water and the constituents of rocks. These communities have not been studied much, but may be an important part of the global carbon cycle . Rock in mines two miles deep also harbour microbes; these live on minute traces of hydrogen produced in slow oxidizing reactions inside the rock. These metabolic reactions allow life to exist in places with no oxygen or light, an environment that had previously been thought to be devoid of life. The intertidal zone and

9752-441: The same area. For example, terrestrial habitat types include forest , steppe , grassland , semi-arid or desert . Fresh-water habitat types include marshes , streams , rivers , lakes , and ponds ; marine habitat types include salt marshes, the coast, the intertidal zone , estuaries , reefs , bays, the open sea, the sea bed, deep water and submarine vents . Habitat types may change over time. Causes of change may include

9858-565: The seabed. Their growth rates and metabolisms tend to be slow, their eyes may be very large to detect what little illumination there is, or they may be blind and rely on other sensory inputs. A number of deep sea creatures are bioluminescent ; this serves a variety of functions including predation, protection and social recognition. In general, the bodies of animals living at great depths are adapted to high pressure environments by having pressure-resistant biomolecules and small organic molecules present in their cells known as piezolytes , which give

9964-455: The section below "by type of climate change impact". Because of changes in extreme weather and sea level rise , due to climate change, the UN has recommended early warning systems as key elements of climate change adaptation and climate risk management . Flooding, cyclones and other rapidly changing weather events can make communities in coastal areas, along floodzones and reliant on agriculture very vulnerable to extreme events. To this end

10070-400: The seeds of which survive the drought, but also some uniquely adapted perennials. Animals adapted to these extreme habitat types also exist; fairy shrimps can lay "winter eggs" which are resistant to desiccation , sometimes being blown about with the dust, ending up in new depressions in the ground. These can survive in a dormant state for as long as fifteen years. Some killifish behave in

10176-531: The setting up of marine reserves. Another international agreement, the Convention on the Conservation of Migratory Species of Wild Animals , protects animals that migrate across the globe and need protection in more than one country. Even where legislation protects the environment, a lack of enforcement often prevents effective protection. However, the protection of habitat types needs to take into account

10282-535: The southeastern United States. Its first intermediate host is a snail and the second, a glass shrimp . The final host is the waterfowl or mammal that consumes the shrimp. Although the vast majority of life on Earth lives in mesophyllic (moderate) environments, a few organisms, most of them microbes , have managed to colonise extreme environments that are unsuitable for more complex life forms. There are bacteria , for example, living in Lake Whillans , half

10388-726: The stewardship of natural resources. As of 2021, the Network is made up of 20 partners representing multiple jurisdictions and sectors of the region. These include: As recognized by the UNESCO Man and the Biosphere Programme , there are currently 738 biosphere regions in 134 countries around the world. Regions are recognized for containing a large variety of ecological systems representative of major biogeographic regions, significant biodiversity, and their ability to explore and demonstrate approaches to sustainable development at

10494-559: The structural diversity in the wood, the greater the number of microhabitat types that will be present. A range of tree species with individual specimens of varying sizes and ages, and a range of features such as streams, level areas, slopes, tracks, clearings, and felled areas will provide suitable conditions for an enormous number of biodiverse plants and animals. For example, in Britain it has been estimated that various types of rotting wood are home to over 1700 species of invertebrate. For

10600-402: The temperature increase to 1.5 °C. Even if greenhouse gas emissions are stopped relatively soon, global warming and its effects will last many years. This is due to the inertia of the climate system . So both carbon neutrality ("net zero") and adaptation are necessary. The Global Goal on Adaptation was also established under the Paris Agreement. The specific targets and indicators for

10706-455: The town's features to make their homes. Rats and mice have followed man around the globe, pigeons , peregrines , sparrows , swallows and house martins use the buildings for nesting, bats use roof space for roosting, foxes visit the garbage bins and squirrels , coyotes , raccoons and skunks roam the streets. About 2,000 coyotes are thought to live in and around Chicago . A survey of dwelling houses in northern European cities in

10812-418: The twentieth century found about 175 species of invertebrate inside them, including 53 species of beetle, 21 flies, 13 butterflies and moths, 13 mites, 9 lice, 7 bees, 5 wasps, 5 cockroaches, 5 spiders, 4 ants and a number of other groups. In warmer climates, termites are serious pests in the urban habitat; 183 species are known to affect buildings and 83 species cause serious structural damage. A microhabitat

10918-460: The water, absorb nutrients and play a part in the reduction of pollution. Rivers Ponds Lakes Marine habitats include brackish water, estuaries, bays, the open sea, the intertidal zone, the sea bed, reefs and deep / shallow water zones. Further variations include rock pools , sand banks , mudflats , brackish lagoons, sandy and pebbly beaches, and seagrass beds, all supporting their own flora and fauna. The benthic zone or seabed provides

11024-562: The way conditions vary rather than changes in average conditions. For example, the average sea level in a port might not be as important as the height of water during a storm surge. That is because a storm surge can cause flooding. The average rainfall in an area might not be as important as how frequent and severe droughts and extreme precipitation events become. Climate change contributes to disaster risk. So experts sometimes see climate change adaptation as one of many processes within disaster risk reduction . In turn, disaster risk reduction

11130-454: The work. In the food production sector, adaptation projects financed through the UNFCCC often include coordination between national governments and administrations at the state, provincial or city level. There are fewer examples of coordination between community-level and national government. Individuals and households play a central role in adaptation. There are many examples particularly in

11236-498: Was recognized by UNESCO in 1988 for ecological and cultural diversity. In 2017, a periodic review brought renewed interest to the Golden Gate Biosphere Network and also expanded the boundaries of the GGB region by more than 26,000 square miles. Since 2017, the Network has focused on expanding its collaborative partnerships to improve connections among regional agencies, organizations, and nonprofits, enhancing
