Forest restoration is defined as "actions to re-instate ecological processes, which accelerate recovery of forest structure, ecological functioning and biodiversity levels towards those typical of climax forest ", i.e. the end-stage of natural forest succession . Climax forests are relatively stable ecosystems that have developed the maximum biomass, structural complexity and species diversity that are possible within the limits imposed by climate and soil and without continued disturbance from humans (more explanation here) . Climax forest is therefore the target ecosystem, which defines the ultimate aim of forest restoration. Since climate is a major factor that determines climax forest composition, global climate change may result in changing restoration aims. Additionally, the potential impacts of climate change on restoration goals must be taken into account, as changes in temperature and precipitation patterns may alter the composition and distribution of climax forests.

134-496: Gnetum africanum ( eru or African jointfir ) is a species of vine native to tropical Africa . Though bearing leaves, the genus Gnetum are gymnosperms , related to pine and other conifers . Gnetum africanum has numerous common names and is grown in various countries across Africa, including: Cameroon ( Eru , okok , m’fumbua , or fumbua ), Angola ( KoKo ), Nigeria ( ukazi , "okazi", or afang ), Gabon (Nkumu), Central African Republic ( KoKo ), Congo ( KoKo ), and

268-770: A confederation of seafaring peoples contributed to the New Kingdom 's collapse in 1069   BC, commencing the Third Intermediate Period . Egypt's collapse liberated the more Egyptianised Kingdom of Kush in Nubia, who manoeuvred into power in Upper Egypt and conquered Lower Egypt in 754   BC to form the Kushite Empire . The Kushites ruled for a century and oversaw a revival in pyramid building , until they were driven out of Egypt by

402-557: A principality into a major power on the trade route between Rome and India through conquering its unfortunately unknown neighbours, gaining a monopoly on Indian Ocean trade in the region. Aksum's rise had them rule over much of the regions from Lake Tana to the valley of the Nile , and they further conquered parts of the ailing Kingdom of Kush , led campaigns against the Noba and Beja peoples, and expanded into South Arabia . This led

536-616: A Berber tribe originally from Yafran (also known as Ifrane ) in northwestern Libya , as well as the city of Ifrane in Morocco . Under Roman rule, Carthage became the capital of the province then named Africa Proconsularis , following its defeat of the Carthaginians in the Third Punic War in 146 BC, which also included the coastal part of modern Libya . The Latin suffix -ica can sometimes be used to denote

670-439: A combination of the following, depending on local needs and aspirations: FLR combines several existing principles and techniques of development, conservation and natural resource management, such as landscape character assessment, participatory rural appraisal , adaptive management etc. within a clear and consistent evaluation and learning framework. An FLR program may comprise various forestry practices on different sites within

804-528: A complementary crop on tree farms. Specifically, it has been suggested that the vine could be used as a complementary crop for rubber and oil trees. However, the necessity for shaded, but not excessively moist, conditions may make it difficult for poor farmers to grow Gnetum africanum if they lack access to suitable lands. However, since Gnetum africanum grows via rhizomes it is not labour-intensive, therefore allowing farmers to focus physical capital elsewhere. Sustainable cultivation practices, such as harvesting

938-418: A fire-adapted forest. In 1998, Costa Rican initiatives were set to regenerate deforested areas, formerly used as cattle pasture. This land was compacted and the soil was depleted, making natural regeneration more difficult. As a partnership with agricultural waste disposals, approximately 12 000 Mg of orange peels and pulp were applied to a 3 hectare segment of the former pastures. This addition of biomass to

1072-710: A former Italian colony, gained independence. In 1956, Tunisia and Morocco won their independence from France. Ghana followed suit the next year (March 1957), becoming the first of the sub-Saharan colonies to be granted independence. Over the next decade, waves of decolonization took place across the continent, culminating in the 1960 Year of Africa and the establishment of the Organisation of African Unity in 1963. Portugal's overseas presence in sub-Saharan Africa (most notably in Angola , Cape Verde, Mozambique , Guinea-Bissau , and São Tomé and Príncipe) lasted from

1206-450: A handful of African countries succeeded in obtaining rapid economic growth prior to 1990. Exceptions include Libya and Equatorial Guinea, both of which possess large oil reserves. Forest restoration Forest restoration is a specialized form of reforestation , but it differs from conventional tree plantations in that its primary goals are biodiversity recovery and environmental protection . Forest and landscape restoration (FLR)

1340-534: A lack of large-scale funding available on behalf of governments to the limited resources and technical capacity of smallholders. Economic indices of success include the value of forest products and ecological services generated (e.g. watershed protection, carbon storage etc.), which ultimately contribute towards poverty reduction. Payments for such ecological services (PES) and forest products can provide strong incentives for local people to implement restoration projects. Active restoration has been shown to accelerate

1474-564: A land (e.g., in Celtica from Celtae , as used by Julius Caesar ). The later Muslim region of Ifriqiya , following its conquest of the Byzantine (Eastern Roman) Empire's Exarchatus Africae , also preserved a form of the name. According to the Romans, Africa lies to the west of Egypt, while "Asia" was used to refer to Anatolia and lands to the east. A definite line was drawn between

1608-483: A larger role in future forest restoration. Forest landscape restoration (FLR) is defined as "a planned process to regain ecological integrity and enhance human well-being in deforested or degraded landscapes". It comprises tools and procedures to integrate site-level forest restoration actions with desirable landscape-level objectives, which are decided upon via various participatory mechanisms among stakeholders. The concept has grown out of collaboration among some of

1742-546: A means to maintain a supplemental income as it is available throughout the year, and may be used as a form of supplementary income for rural farmers in Cameroon. Healthy leaves with a thick wax-like texture are preferred in markets and will receive the highest value; Gnetum africanum remains untaxed in local markets. Since the leaves may be consumed as a vegetable and the root tuber as a famine food, it may also increase overall food security of rural households. Gnetum africanum

1876-698: A millennium. Towards the end of the ancient period, northern Ethiopia and Eritrea bore the Kingdom of D'mt beginning in 980   BC. In modern-day Somalia and Djibouti there was the Macrobian Kingdom , with archaeological discoveries indicating the possibility of other unknown sophisticated civilisations at this time. After D'mt's fall in the 5th century BC the Ethiopian Plateau came to be ruled by numerous smaller unknown kingdoms who experienced strong south Arabian influence , until

2010-625: A monopoly on gold heading north and salt heading south, despite not controlling the gold fields themselves, located in the forest regions . It is probable that Wagadu's dominance on trade allowed for the gradual consolidation of many polities into a confederated state , whose composites stood in varying relations to the core, from fully administered to nominal tribute-paying parity. Based on large tumuli scattered across West Africa dating to this period, it has been stipulated that relative to Wagadu, there were further simultaneous and preceding kingdoms that have unfortunately been lost to time. At

2144-586: A native Libyan tribe, an ancestor of modern Berbers ; see Terence for discussion. The name had usually been connected with the Phoenician word ʿafar meaning "dust", but a 1981 hypothesis has asserted that it stems from the Berber word ifri (plural ifran ) meaning "cave", in reference to cave dwellers. The same word may be found in the name of the Banu Ifran from Algeria and Tripolitania ,

2278-426: A root tuber that may be used as a source of famine food , and is similar to that of a yam. Finally, the seeds of the vine may also be eaten cooked. Gnetum africanum is a good source of protein and is strong in essential and non-essential amino acids. It is high in glutamic acid , leucine , and aspartic acid , with low levels of histidine , and cysteine , while there appears to be trace amounts of tryptophan in

2412-608: A seed source within the landscape. Even in protected areas, there are often large deforested sites: logged over areas or sites formerly cleared for agriculture. If protected areas are to act as Earth's last wildlife refuges, restoration of such areas will be needed. Many restoration projects are now being implemented under the umbrella of " forest landscape restoration " (FLR), defined as a "planned process to regain ecological integrity and enhance human well-being in deforested or degraded landscapes". FLR recognizes that forest restoration has social and economic functions. It aims to achieve

2546-421: A stake in what is growing, if restoration is to sustain." A recent FAO publication reports that Indigenous Peoples are among those facing the greatest risk to their well-being and livelihoods from the effects of climate change, and therefore must be centred in forest restoration and conservation. The Ashland Forest Resiliency Stewardship Project (AFR) is a decade long, science-based project launched in 2010 with

2680-468: A transition from " informal imperialism " – military influence and economic dominance – to direct rule. Imperial rule by Europeans continued until after the conclusion of World War II , when almost all remaining colonial territories gradually obtained formal independence. Independence movements in Africa gained momentum following World War II, which left the major European powers weakened. In 1951, Libya,

2814-455: A vegetable for soups and stews, commonly called eru soup, okazi soup or afang soup . The leaves of the vine are sold in markets throughout the year and may be used in soups and stews or eaten raw. The leaves may further be used as a remedy for nausea , sore throats, or as a dressing for warts. The stem of the plant may also be eaten for medicinal purposes, including the reduction of pain during childbirth. Furthermore, Gnetum africanum produces

2948-484: A wide range of stakeholders including local communities, government officials, non-government organizations, scientists and funding agencies. Its ecological success is measured in terms of increased biological diversity, biomass, primary productivity , soil organic matter and water-holding capacity, as well as the return of rare and keystone species , characteristic of the target ecosystem. However, according to FAO, restoration activities face economic barriers ranging from

3082-399: Is appropriate wherever biodiversity recovery is one of the main goals of reforestation, such as for wildlife conservation, environmental protection, eco-tourism or to supply a wide variety of forest products to local communities. Forests can be restored in a wide range of circumstances, but degraded sites within protected areas are a high priority, especially where some climax forest remains as

3216-541: Is defined as a process that aims to regain ecological functionality and enhance human well-being in deforested or degraded landscapes . FLR has been developed as a response to the growing degradation and loss of forest and land, which resulted in declined biodiversity and ecosystem services . Effective FLR will support the achievement of the Sustainable Development Goals . The United Nations Decade on Ecosystem Restoration (2021–2030) provides

3350-661: Is most significantly cultivated by rural women farmers, constituting approximately 80% of the overall trade of this crop. While Gnetum africanum is still largely considered a wild vegetable, if cultivated as a domesticated crop it may save time for women who previously would search for it in the forests. Africa Africa is the world's second-largest and second-most populous continent after Asia . At about 30.3 million km (11.7 million square miles) including adjacent islands, it covers 20% of Earth 's land area and 6% of its total surface area. With nearly 1.4 billion people as of 2021, it accounts for about 18% of

3484-631: Is not always essential to restore forest ecosystems. A lot can be achieved by studying how forests regenerate naturally, identifying the factors that limit regeneration and devising methods to overcome them. These can include weeding and adding fertilizer around natural tree seedlings, preventing fire, removing cattle and so on. This is "accelerated" or "assisted" natural regeneration . It is simple and cost-effective, but it can only operate on trees that are already present, mostly light-loving pioneer species . Such tree species are not usually those that comprise climax forests, but they can foster recolonization of

3618-791: Is not always to be taken literally. Africa is considered by most paleoanthropologists to be the oldest inhabited territory on Earth, with the Human species originating from the continent. During the mid-20th century, anthropologists discovered many fossils and evidence of human occupation perhaps as early as seven million years ago ( Before present , BP). Fossil remains of several species of early apelike humans thought to have evolved into modern humans, such as Australopithecus afarensis radiometrically dated to approximately 3.9–3.0 million years BP, Paranthropus boisei (c. 2.3–1.4 million years BP) and Homo ergaster (c. 1.9 million–600,000 years BP) have been discovered. After

3752-562: Is referred to as the wildland–urban interface (WUI). Historically, the forests of this region experienced a relatively frequent fire return interval, which prevented buildup of heavy fuel loads. A century of fire exclusion and suppression on federal lands in the Pacific Northwest has led to increased forest density and fuel loads, and thus a more persistent threat of devastating wildfire. The AFR project has implemented restoration techniques and prescriptions that aim to replicate

3886-567: Is slow. Forest restoration, when implemented appropriately, helps restore habitats and ecosystems, create jobs and income and is an effective nature-based solution to climate change. Moreover, according to FAO, forest and landscape restoration yields many benefits for the climate, including greenhouse gas emissions sequestration and reduction. The United Nations Decade on Ecosystem Restoration 2021–2030, announced in March 2019, aims to accelerate ecosystem restoration action worldwide. Forest restoration

9782-659: The Great in 332   BC marked the beginning of Hellenistic rule and the installation of the Macedonian Ptolemaic dynasty in Egypt. The Ptolemaics lost their holdings outside of Africa to the Seleucids in the Syrian Wars , expanded into Cyrenaica and subjugated Kush in the 3rd century BC. In the 1st century BC, Ptolemaic Egypt became entangled in a Roman civil war , leading to its conquest by

9916-581: The Iberian peninsula during the eleventh century. The Banu Hilal and Banu Ma'qil were a collection of Arab Bedouin tribes from the Arabian Peninsula who migrated westwards via Egypt between the eleventh and thirteenth centuries. Their migration resulted in the fusion of the Arabs and Berbers, where the locals were Arabized , and Arab culture absorbed elements of the local culture, under

10050-544: The Ibibio, Efik and Annang people of Nigeria. However, it has been noted that the vine grows best in well-shaded areas similar to that of a forest, as too much sunlight can burn the vine and produce substandard leaves for selling purposes. It has also been noted that the vine does not grow particularly well in very moist conditions such as marshes and swamps. Gnetum africanum has been found to be negatively impacted if grown on or next to termite infected wood or trees. However,

10184-563: The Persian prophet Mani to consider Aksum as one of the four great powers of the 3rd century AD alongside Persia , Rome , and China . In the 4th century AD Aksum's king converted to Christianity and Aksum's population, who had followed syncretic mixes of local beliefs , slowly followed. The end of the 5th century saw Aksum allied with the Byzantine Empire , who viewed themselves as defenders of Christendom , balanced against

10318-575: The Romans in the Second Punic War, Mauretania , a Mauri tribal kingdom and home of the legendary King Atlas , and various tribes such as Garamantes , Musulamii , and Bavares . The Third Punic War would result in Carthage's total defeat in 146 BC and the Romans established the province of Africa , with Numidia assuming control of many of Carthage's African ports. Towards the end of

10452-833: The Sahara region was becoming increasingly dry and hostile. Around 3500   BC, due to a tilt in the Earth's orbit , the Sahara experienced a period of rapid desertification. The population trekked out of the Sahara region towards the Nile Valley below the Second Cataract where they made permanent or semi-permanent settlements. A major climatic recession occurred, lessening the heavy and persistent rains in Central and Eastern Africa . Since this time, dry conditions have prevailed in Eastern Africa and, increasingly during

10586-522: The Saharan climate started to become drier at an exceedingly fast pace. This climate change caused lakes and rivers to shrink significantly and caused increasing desertification . This, in turn, decreased the amount of land conducive to settlements and encouraged migrations of farming communities to the more tropical climate of West Africa. During the first millennium BC, a reduction in wild grain populations related to changing climate conditions facilitated

10720-493: The best possible compromise between meeting both conservation goals and the needs of rural communities. As human pressure on landscapes increases, forest restoration will most commonly be practiced within a mosaic of other forms of forest management, to meet the economic needs of local people. A recent focal area for forest restoration efforts is within the urban context, where both people and biodiversity will benefit, however this context presents unique challenges. Tree planting

10854-549: The carbon recovery of human-modified tropical forests by as much as 50%. According to FAO 's The State of the World’s Forests 2020 , large-scale forest restoration is needed to meet the Sustainable Development Goals and to prevent, halt and reverse the loss of biodiversity . While 61 countries have, together, pledged to restore 170 million hectares of degraded forest lands under the Bonn Challenge, progress to date

10988-550: The continent and its countries are in the Northern Hemisphere , with a substantial portion and a number of countries in the Southern Hemisphere . Most of the continent lies in the tropics, except for a large part of Western Sahara , Algeria , Libya and Egypt , the northern tip of Mauritania , and the entire territories of Morocco , Ceuta , Melilla , and Tunisia , which in turn are located above

11122-463: The continent as a whole has trended towards more democratic governance. Upon independence an overwhelming majority of Africans lived in extreme poverty . The continent suffered from the lack of infrastructural or industrial development under colonial rule, along with political instability. With limited financial resources or access to global markets, relatively stable countries such as Kenya still experienced only very slow economic development. Only

11256-424: The continent most vulnerable to climate change . The history of Africa is long, complex, and varied, and has often been under-appreciated by the global historical community . In African societies the oral word is revered, and they have generally recorded their history via oral tradition , which has led anthropologists to term them oral civilisations, contrasted with literate civilisations which pride

11390-461: The continent's south. The Bantu expansion constituted a major series of migrations of Bantu peoples from central Africa to eastern and southern Africa and was substantial in the settling of the continent. Commencing in the 2nd millennium BC, the Bantu began to migrate from Cameroon to central, eastern, and southern Africa, laying the foundations for future states such as the Kingdom of Kongo in

11524-478: The continent. Africa, particularly Eastern Africa , is widely accepted to be the place of origin of humans and the Hominidae clade , also known as the great apes . The earliest hominids and their ancestors have been dated to around 7 million years ago, and Homo sapiens (modern human) are believed to have originated in Africa 350,000 to 260,000 years ago. Africa is also considered by anthropologists to be

11658-428: The earliest instances of agriculture in human history. Its cultivation would gradually spread across Africa, before spreading to India around 2000   BC. People around modern-day Mauritania started making pottery and built stone settlements (e.g., Tichitt , Oualata ). Fishing, using bone-tipped harpoons , became a major activity in the numerous streams and lakes formed from the increased rains. In West Africa,

11792-543: The end of the Ice ages , estimated to have been around 10,500   BC, the Sahara had again become a green fertile valley, and its African populations returned from the interior and coastal highlands in sub-Saharan Africa , with rock art paintings depicting a fertile Sahara and large populations discovered in Tassili n'Ajjer dating back perhaps 10 millennia. However, the warming and drying climate meant that by 5,000   BC,

11926-588: The evolution of Homo sapiens approximately 350,000 to 260,000 years BP in Africa, the continent was mainly populated by groups of hunter-gatherers . These first modern humans left Africa and populated the rest of the globe during the Out of Africa II migration dated to approximately 50,000 years BP, exiting the continent either across Bab-el-Mandeb over the Red Sea , the Strait of Gibraltar in Morocco, or

12060-660: The expansion of farming communities and the rapid adoption of rice cultivation around the Niger River. By the first millennium BC, ironworking had been introduced in Northern Africa. Around that time it also became established in parts of sub-Saharan Africa, either through independent invention there or diffusion from the north and vanished under unknown circumstances around 500   AD, having lasted approximately 2,000 years, and by 500   BC, metalworking began to become commonplace in West Africa. Ironworking

12194-506: The growth and expansion of Aksum in the 1st century BC. Along the Horn's coast there were many ancient Somali city-states that thrived off of the wider Red Sea trade and transported their cargo via beden , exporting myrrh , frankincense , spices , gum , incense , and ivory , with freedom from Roman interference causing Indians to give the cities a lucrative monopoly on cinnamon from ancient India . The Kingdom of Aksum grew from

12328-443: The historical process is largely a communal one, with eyewitness accounts, hearsay , reminiscences, and occasionally visions , dreams, and hallucinations, crafted into oral traditions . Time is sometimes mythical and social, and truth generally viewed as relativist . Oral tradition can be exoteric or esoteric . It speaks to people according to their understanding, unveiling itself in accordance with their aptitudes, and

12462-519: The intent of reducing severe wildfire risk, but also protecting water quality, old-growth forest, wildlife, people, property, and the overall quality of life within the Ashland watershed. The primary stakeholders in this cooperative restoration effort are the U.S. Forest Service, the City of Ashland, Lomakatsi Restoration Project, and The Nature Conservancy. The project was launched with initial funding from

12596-572: The kingdoms of Lower Egypt and Upper Egypt in northeast Africa . Around 3100   BC Upper Egypt conquered Lower Egypt to unify Egypt under the 1st dynasty , with the process of consolidation and assimilation completed by the time of the 3rd dynasty who formed the Old Kingdom of Egypt in 2686   BC. The Kingdom of Kerma emerged around this time to become the dominant force in Nubia , controlling territory as large as Egypt between

12730-464: The landscape level. It includes actions to strengthen the resilience and ecological integrity of landscapes and thereby keep future management options open. The participation of local communities is central to the concept, because they play a critical role in shaping the landscape and gain significant benefits from restored forest resources. Therefore, FLR activities are inclusive and participatory. The desirable outcomes of an FLR program usually comprise

12864-466: The landscape, depending on local environmental and socioeconomic factors. These may include protection and management of secondary and degraded primary forests, standard forest restoration techniques such as "assisted" or "accelerated" natural regeneration (ANR) and the planting of framework tree species to restore degraded areas, as well as conventional tree plantations and agroforestry systems to meet more immediate monetary needs. The IUCN hosts

12998-513: The largest number of megafauna species, as it was least affected by the extinction of the Pleistocene megafauna . However, Africa also is heavily affected by a wide range of environmental issues , including desertification, deforestation, water scarcity , and pollution . These entrenched environmental concerns are expected to worsen as climate change impacts Africa . The UN Intergovernmental Panel on Climate Change has identified Africa as

13132-616: The last 200 years, in Ethiopia . The domestication of cattle in Africa preceded agriculture and seems to have existed alongside hunter-gatherer cultures. It is speculated that by 6,000   BC, cattle were domesticated in North Africa. In the Sahara-Nile complex, people domesticated many animals, including the donkey and a small screw-horned goat that was common from Algeria to Nubia . Between 10,000 and 9,000   BC, pottery

13266-475: The leaves regularly rather than uprooting the whole vine, allows for a more viable supplementary income throughout the year. The FAO has found that the vine is easier to reproduce by cuttings than by growing from seeds. The Centre for International Forestry Research (CIFOR) has been working with women to create sustainable cultivation practices of Gnetum africanum , as well as forest restoration techniques. Specifically, near Lekie, Cameroon, CIFOR has been helping

13400-660: The most genetically diverse continent as a result of being the longest inhabited. In the 4th and 3rd millennia BC Ancient Egypt , Kerma , Punt , and the Tichitt Tradition emerged in North , East and West Africa , while from 4000 BC until 1000 AD the Bantu expansion was substantial in laying the foundations for societies and states in Central , East , and Southern Africa . Some African empires include Wagadu , Mali , Songhai , Sokoto , Ife , Benin , Asante ,

13534-399: The most lucrative trading locations in the Gulf of Tunis . Phoenician settlements subsequently grew into Ancient Carthage after gaining independence from Phoenicia in the 6th century BC, and they would build an extensive empire and a strict mercantile network, all secured by one of the largest and most powerful navies in the ancient Mediterranean . Carthage would meet its demise in

13668-439: The official religion, built mosques, and brought to Gao Muslim scholars, including al-Maghili (d.1504), the founder of an important tradition of Sudanic African Muslim scholarship. By the eleventh century, some Hausa states – such as Kano , Jigawa , Katsina , and Gobir – had developed into walled towns engaging in trade, servicing caravans , and the manufacture of goods. Until the fifteenth century, these small states were on

13802-465: The opportunities afforded by north–south diversity in ecosystems. Various civilisations prospered in this period. From 4000   BC, the Tichitt culture in modern-day Mauritania and Mali was the oldest known complexly organised society in West Africa, with a four tiered hierarchical social structure. Other civilisations include the Kintampo culture from 2500   BC in modern-day Ghana ,

13936-588: The opportunity to restore hundreds of millions of hectares of degraded forests and other ecosystems. Successful ecosystem restoration requires a fundamental understanding of the ecological characteristics of the component species, together with knowledge of how they assemble, interact and function as communities Forest restoration may include simply protecting remnant vegetation (fire prevention, cattle exclusion etc.) or more active interventions to accelerate natural regeneration, as well as tree planting and/or sowing seeds ( direct seeding ) of species characteristic of

14070-534: The periphery of the major Sudanic empires of the era, paying tribute to Songhai to the west and Kanem-Borno to the east. Slavery had long been practiced in Africa. Between the 15th and the 19th centuries, the Atlantic slave trade took an estimated 7–12 million slaves to the New World. In addition, more than 1 million Europeans were captured by Barbary pirates and sold as slaves in North Africa between

14204-568: The plant. The content of amino acids found in Gnetum africanum is similar to recommended levels by the FAO. It has also been found that the levels of iodine are also high in the vine. Fibre levels average approximately 33.4 g/100 g of dried Gnetum africanum leaves, while recommended daily intake of fibre is 30 g. Gnetum africanum has been noted as an anti-inflammatory, anticarcinogenic and antioxidant. Economically, Gnetum africanum can be used as

14338-599: The predecessor to the African Union. The nascent countries decided to keep their colonial borders, with traditional power structures used in governance to varying degrees. Afri was a Latin name used to refer to the inhabitants of what was then known as northern Africa , located west of the Nile river, and in its widest sense referring to all lands south of the Mediterranean , also known as Ancient Libya . This name seems to have originally referred to

14472-469: The process of ecological succession in dry, mixed-conifer forests of the Pacific Northwest. The approach involves a combination of fuels reduction, thinning small-diameter trees, and carrying out prescribed burns. Priority is given to maintaining ecological function and complexity by retaining the largest and oldest trees, preserving wildlife habitat and riparian areas, and protecting erodible soils and maintaining slope stability. Since its inception in 2010,

14606-527: The productivity of the vine appears to be resistant to a significant proportion of diseases. The vine is largely understudied, and more research is needed to verify plant susceptibility and resilience to viruses, diseases, and fungi. Gnetum africanum depletion is largely associated with tree felling and overexploitative forestry practices. Overexploitation is partly caused by unsustainable forest clearing practices throughout regions in Africa. Since Gnetum africanum grows best in shaded areas it could be used as

14740-489: The public sector. According to FAO, bridging the gap between smallholders and investors, coordinating investment, promoting local ownership of FLR financing strategies, and the development of bankable projects and blended financial mechanisms generate positive outcomes for FLR impact at scale.

In the 5th century AD the Vandals conquered north Africa precipitating the fall of Rome . Swathes of indigenous peoples would regain self-governance in

15008-447: The scaling-up of enterprises for sustainable restoration. Several options are available to finance restoration. To meet the unique demands of individual FLR projects, it is critical to identify the best landscape financing strategy. Financial options that generate diverse incentives for local actors may either be for-profit mechanisms, such as debt or loans, or not-for-profit mechanisms which include grants, fiscal policies, or expenses by

15142-431: The site by shade-tolerant climax forest tree species, via natural seed dispersal from remnant forest. Because this is a slow process, biodiversity recovery can usually be accelerated by planting some climax forest tree species, especially large-seeded, poorly dispersed species. It is not feasible to plant all the tree species that may have formerly grown in the original primary forest and it is usually unnecessary to do so, if

15276-478: The soil allowed for a 176% increase in woody plant growth, increased species richness, tripled tree evenness (measured through the Shannon Index), and significantly elevated soil nutrient levels, measured at 2 and 16 years following the application (Truer et al . 2018). A significant increase in canopy closure was also observed using hemispheric topography, further suggesting that agricultural waste may play

15410-552: The soil conditions through erosion and desertification . This indeed has dire consequences on both the quality of the habitats and their related fauna. Nevertheless, in some specific cases, wild fires do actually allow to increase the bio diversity index of the burnt area, in which case the Forest Restoration Strategies tend to look for a different land-use. A study finds that almost 300 million people live on tropical forest restoration opportunity land in

15544-876: The species have been planted in Cameroon’s Limbe Botanic Garden to begin a gene bank. Gnetum africanum is found mainly in the humid tropical forest regions of Central African Republic , Cameroon , Gabon , Republic of the Congo , Democratic Republic of the Congo and Angola . It has been found in primary and secondary semi-deciduous humid forests, both in dense and sunny transitional savannah locations, ranging from sea-level to 1200 meter altitude. The shade tolerant vine does not grow well in direct sunlight and can be found climbing on middle and under-story trees. This vine will grow in all seasons and typically spreads along forest floors. The vine grows in two ways: through rhizomes, or through new shoots that grow where

15678-403: The stem has been cut. As Gnetum africanum is a wild forest vine, it tends to grow best in shaded areas. Input requirements for Gnetum africanum have not yet been established, and nutrient requirements are currently unknown as well. This is likely due to the fact that the vine is traditionally a wild vegetable. The plant has now been domesticated and grown for subsistence and commercial use among

15812-442: The target ecosystem. Tree species planted (or encouraged to establish) are those that are typical of, or provide a critical ecological function in, the target ecosystem. However, wherever people live in or near restoration sites, restoration projects often include economic species amongst the planted trees, to yield subsistence or cash-generating products. Forest restoration is an inclusive process, which depends on collaboration among

15946-488: The two continents by the geographer Ptolemy (85–165 CE), indicating Alexandria along the Prime Meridian and making the isthmus of Suez and the Red Sea the boundary between Asia and Africa. As Europeans came to understand the real extent of the continent, the idea of "Africa" expanded with their knowledge. Other etymological hypotheses have been postulated for the ancient name "Africa": In African societies,

16080-512: The understory of forests, they can easily over-graze a freshly replanted swath of forest, where young samplings are easily accessible. Over-grazing is particularly problematic in this case as the samplings and other young plants may be damaged beyond the point of recovery, resulting in a decrease in biodiversity. Care must be taken to use "deer fencing" to protect the regeneration area, or where not financially possible, to plant trees which prioritize structural growth and recovery. In large parts of

16214-496: The unifying framework of Islam. Following the breakup of Mali, a local leader named Sonni Ali (1464–1492) founded the Songhai Empire in the region of middle Niger and the western Sudan and took control of the trans-Saharan trade. Sonni Ali seized Timbuktu in 1468 and Jenne in 1473, building his regime on trade revenues and the cooperation of Muslim merchants. His successor Askia Mohammad I (1493–1528) made Islam

16348-478: The vine will produce small cone-like reproductive structures. The seeds of the vine resemble a fleshy fruit, sized 10–15 mm × 4–8 mm, and are red-orange in colour when fully ripe. Gnetum africanum may also be known as G. buchholzianum , and is one of the two vine species from the Gnetum genus that grown in Africa. There are currently no gene banks for Gnetum africanum , but approximately 19 varieties of

16482-454: The way forward provides an overview of funding sources and financial instruments available for FLR activities. To finance the planning and implementation of forest and landscape restoration (FLR) activities, the Food and Agriculture Organization of the United Nations (FAO) has identified diverse financial mechanisms that tailor to different stages of the FLR process and cover the transaction and

16616-516: The wet phase ushered in an expanding rainforest and wooded savanna from Senegal to Cameroon . Between 9,000 and 5,000   BC, Niger–Congo speakers domesticated the oil palm and raffia palm . Black-eyed peas and voandzeia (African groundnuts), were domesticated, followed by okra and kola nuts . Since most of the plants grew in the forest, the Niger–Congo speakers invented polished stone axes for clearing forest. Around 4,000   BC,

16750-516: The women remove an invasive plant species (kodengui), and replacing it with Gnetum africanum , in order to discourage regrowth of the invasive species and utilize the area for a more sustainable resource. Subsistence agriculturalists in Cameroon may be able to improve their nutritional, environmental, social, and economic situations by growing this vine. Nutrition can be improved by using the plant for medicinal purposes as well as through edible consumption. Primarily, Gnetum africanum leaves are used as

16884-497: The world's human population . Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will reach 3.8 billion people by 2099. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania . Scholars have attributed this to different factors including geography , climate , corruption , colonialism ,

17018-737: The world's major international conservation organizations including the International Union for Conservation of Nature (IUCN), the World Wide Fund for Nature (WWF), the World Resources Institute and the International Tropical Timber Organization (ITTO). The concept of FLR was conceived to bring about compromises between meeting the needs of both humans and wildlife, by restoring a range of forest functions at

17152-435: The world, forest fires cover a heavy toll on forests. That can be because of provoked deforestation in order to substitute forests by crop areas, or in dry areas, because of wild fires occurring naturally or intentionally. A whole section of forest landscape restoration in linked to this particular problem, as in many cases, the net loss of ecosystem value is very high and can open the drop to an accelerated further degradation of

17286-418: Was rapidly conquered and colonised by European nations , save for Ethiopia and Liberia . European rule had significant impacts on Africa's societies , and colonies were maintained for the purpose of economic exploitation and extraction of natural resources. Most present states emerged from a process of decolonisation following World War II , and established the Organisation of African Unity in 1963,

17420-503: Was established around the ninth century, making it one of the oldest kingdoms in present-day Nigeri. The Nri kingdom is famous for its elaborate bronzes , found at the town of Igbo-Ukwu . The Kingdom of Ife , historically the first of these Yoruba city-states or kingdoms, established government under a priestly oba ('king' or 'ruler' in the Yoruba language ), called the Ooni of Ife . Ife

17554-450: Was fully established by roughly 500   BC in many areas of East and West Africa, although other regions did not begin ironworking until the early centuries AD. Copper objects from Egypt , North Africa, Nubia, and Ethiopia dating from around 500   BC have been excavated in West Africa, suggesting that Trans-Saharan trade networks had been established by this date. From 3500   BC, nomes (ruled by nomarchs ) coalesced to form

17688-609: Was independently invented in the region of Mali in the savannah of West Africa. In the steppes and savannahs of the Sahara and Sahel in Northern West Africa, people possibly ancestral to modern Nilo-Saharan and Mandé cultures started to collect wild millet , around 8,000 to 6,000   BC. Later, gourds , watermelons , castor beans , and cotton were also collected. Sorghum was first domesticated in Eastern Sudan around 4,000   BC, in one of

17822-558: Was noted as a major religious and cultural centre in West Africa and for its unique naturalistic tradition of bronze sculpture. The Ife model of government was adapted by the Oyo Empire , whose obas, called the Alaafins of Oyo , controlled many other Yoruba and non-Yoruba city-states and kingdoms including the Fon Kingdom of Dahomey . The Almoravids were a Berber dynasty from the Sahara that spread over northwestern Africa and

17956-514: Was one of the first African countries to gain independence, the state remained under the control of the country's white minority, initially through qualified voting rights and from 1956 by a system of racial segregation known as apartheid , until 1994. Today, Africa contains 54 sovereign countries. Since independence, African states have frequently been hampered by instability, corruption, violence, and authoritarianism. The vast majority of African states are republics that operate under some form of
