Biodiversity in agriculture Biodiversity in agriculture is the measure of biodiversity found on agricultural land. Biodiversity is the total diversity of species present in an area at all levels of biological organization . It

148-413: A genetic bottleneck The decreased gene pool threatens species through factors such as inbreeding depression , where the less advantageous populations lowers the species survival rates. Monoculture is the practice of producing a single crop on a given piece of land, including crop rotation . While monoculture produces optimum yields, it has implications for the biodiversity of farms. Heterogeneity ,

185-571: A biotic and abiotic diversity. Since 1966, the Green Revolution enhanced agricultural productivity through technological, economical, and political advancements in an effort to increase food security globally. This includes the introduction of genetically modified crops , which allows for increased yield, pest resistance, and improved crop varieties. These advancements also led to increased global geographical spread of 52 agricultural crops with cereals such as wheat, rice, and maize showing

222-609: A faculty at the Federal University of Paraná , in Curitiba. Today, forestry education typically includes training in general biology , ecology , botany , genetics , soil science , climatology , hydrology , economics and forest management . Education in the basics of sociology and political science is often considered an advantage. Professional skills in conflict resolution and communication are also important in training programs. In India, forestry education

259-455: A mixture of the two. Techniques include timber extraction, planting and replanting of different species , building and maintenance of roads and pathways through forests, and preventing fire . The first dedicated forestry school was established by Georg Ludwig Hartig at Hungen in the Wetterau , Hesse , in 1787, though forestry had been taught earlier in central Europe, including at

296-455: A region. A related discipline is the study of sylvics, which focuses on the autecology of genera and species. The provenance of forest reproductive material used to plant forests has a great influence on how the trees develop, hence why it is important to use forest reproductive material of good quality and of high genetic diversity . More generally, all forest management practices, including in natural regeneration systems , may impact

333-643: Is a transformative process to any habitat, with a main focus on cultivating crops for human consumption. Views on ecosystem services can be presented through viewpoints that benefit humans environmentally, economically, and culturally to motivate the practices that support ecosystem services in the agricultural industry. For example, low crop diversity can increase pests and their resistance to pesticides, resulting in large ecological disturbances and economical losses. This can be mitigated with increased crop rotation, which contributes to more diverse soil microbiota and insects that provide ecosystem services. Another example

370-929: Is an important economic segment in various industrial countries, as forests provide more than 86 million green jobs and support the livelihoods of many more people. For example, in Germany, forests cover nearly a third of the land area, wood is the most important renewable resource , and forestry supports more than a million jobs and about €181 billion of value to the German economy each year. Worldwide, an estimated 880 million people spend part of their time collecting fuelwood or producing charcoal, many of them women.  Human populations tend to be low in areas of low-income countries with high forest cover and high forest biodiversity, but poverty rates in these areas tend to be high. Some 252 million people living in forests and savannahs have incomes of less than US$ 1.25 per day. Over

407-453: Is characterized by heterogeneous habitats that support the diverse ecological structure. In agricultural areas, biodiversity decreases as varying landscapes are lost and native plants are replaced with cultivated crops . Increasing biodiversity in agriculture can increase the sustainability of farms through the restoration of ecosystem services that aid in regulating agricultural lands. Biodiversity in agriculture can be increased through

444-462: Is essential in providing ecosystem services, which conserves biodiversity while providing agricultural services. Agriculture creates a conflict over the use of land between wildlife and humans. Land use for agriculture has been a driving force in creating biodiversity loss An increase in the amount of pasture and crop land over the last few hundred years has led to the rapid loss of natural habitats . The Food and Agriculture Organization of

481-644: Is imparted in the agricultural universities and in Forest Research Institutes (deemed universities). Four year degree programmes are conducted in these universities at the undergraduate level. Masters and Doctorate degrees are also available in these universities. In the United States, postsecondary forestry education leading to a Bachelor's degree or Master's degree is accredited by the Society of American Foresters . In Canada

518-501: Is just as important on farms and in fields as it is in deep river valleys or mountain cloud forests". In recent years, the world has acknowledged the value of biodiversity through treaties formed, such as in the 1992 Convention on Biological Diversity . The loss of habitat connectivity caused by fragmentation in agricultural areas threatens biodiversity, as it decreases population sizes and restricts its access to external resources. Species facing habitat fragmentation can also create

555-484: Is land size, where a study proved a relationship between smaller agricultural fields and increased species richness. The area of an agricultural field is associated with organisms accessibility to the edges of the field, which usually allow access for fields with different biophysical and geophysical features. Increased accessibility to a diverse ecological features increases heterogeneity and reduces edge effects on populations inhabiting agricultural fields. Agriculture

592-624: Is mainly suitable to regions with small-scale multi-functional forest management systems Forestry literature is the books, journals and other publications about forestry. The first major works about forestry in the English language included Roger Taverner 's Booke of Survey (1565), John Manwood 's A Brefe Collection of the Lawes of the Forrest (1592) and John Evelyn 's Sylva (1662).

629-520: Is no sharp boundary between plant taxonomy and dendrology; woody plants not only belong to many different plant families , but these families may be made up of both woody and non-woody members. Some families include only a few woody species . Dendrology, as a discipline of industrial forestry, tends to focus on identification of economically useful woody plants and their taxonomic interrelationships. As an academic course of study, dendrology will include all woody plants, native and non-native, that occur in

666-436: Is the biological science of studying forests and woodlands , incorporating the understanding of natural forest ecosystems , and the effects and development of silvicultural practices. The term complements silviculture , which deals with the art and practice of forest management. Silvology is seen as a single science for forestry and was first used by Professor Roelof A.A. Oldeman at Wageningen University . It integrates

703-482: Is the extraction of forest products, are planned and managed to utilize a mix of ecological and agroecological principles. In many regions of the world there is considerable conflict between forest practices and other societal priorities such as water quality, watershed preservation, sustainable fishing, conservation, and species preservation. Silvology ( Latin : silva or sylva , "forests and woods"; Ancient Greek : -λογία , -logia , "science of" or "study of")

740-431: Is the foundation of biological diversity at species and ecosystem levels. Forest genetic resources are therefore important to consider in forest management. Genetic diversity in forests is threatened by forest fires , pests and diseases, habitat fragmentation , poor silvicultural practices and inappropriate use of forest reproductive material. About 98 million hectares of forest were affected by fire in 2015; this

777-412: Is the science and craft of creating, managing, planting, using, conserving and repairing forests and woodlands for associated resources for human and environmental benefits. Forestry is practiced in plantations and natural stands . The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences. Forest management plays an essential role in

814-776: The University of Giessen , in Hesse-Darmstadt . In Spain, the first forestry school was the Forest Engineering School of Madrid ( Escuela Técnica Superior de Ingenieros de Montes ), founded in 1844. The first in North America, the Biltmore Forest School was established near Asheville , North Carolina, by Carl A. Schenck on September 1, 1898, on the grounds of George W. Vanderbilt's Biltmore Estate . Another early school

851-744: The effects of climate change . Most countries in Europe have recommendations or guidelines for selecting species and provenances that can be used in a given site or zone. Forest management is a branch of forestry concerned with overall administrative, legal, economic, and social aspects, as well as scientific and technical aspects, such as silviculture , forest protection , and forest regulation . This includes management for timber, aesthetics , recreation , urban values, water , wildlife , inland and nearshore fisheries, wood products , plant genetic resources , and other forest resource values . Management objectives can be for conservation, utilisation, or

888-589: The 1920s and 1930 she and her family, along with other families of their social circle in London, used to have vacations in Varengeville: "At the small village of Varengeville, on top of the cliffs a few miles west of Dieppe , the families with children lived in fairly basic chalets which were fine for us. We ate at the hotel and went down a steep path to the sand and rather chilly swimming, and tremendously enjoyed each other's company". Forestry Forestry

925-1211: The Canadian Institute of Forestry awards silver rings to graduates from accredited university BSc programs, as well as college and technical programs. In many European countries, training in forestry is made in accordance with requirements of the Bologna Process and the European Higher Education Area . The International Union of Forest Research Organizations is the only international organization that coordinates forest science efforts worldwide. In order to keep up with changing demands and environmental factors, forestry education does not stop at graduation. Increasingly, forestry professionals engage in regular training to maintain and improve on their management practices. An increasingly popular tool are marteloscopes ; one hectare large, rectangular forest sites where all trees are numbered, mapped and recorded. These sites can be used to do virtual thinnings and test one's wood quality and volume estimations as well as tree microhabitats . This system

962-519: The United Nations estimates that more than 40% of Earth's land surface is currently used for agriculture. Because so much land has been converted to agriculture, habitat loss is recognized as the driving force in biodiversity loss. A decline in farmland biodiversity can be traced to changes in farming practices and increased agricultural intensity. Nonetheless, according to the FAO, "biodiversity

999-589: The creation and modification of habitats and affects ecosystem services provisioning. Modern forestry generally embraces a broad range of concerns, in what is known as multiple-use management, including: the provision of timber , fuel wood, wildlife habitat , natural water quality management , recreation , landscape and community protection, employment, aesthetically appealing landscapes , biodiversity management, watershed management , erosion control , and preserving forests as " sinks " for atmospheric carbon dioxide . Forest ecosystems have come to be seen as

1036-564: The diversity of the landscape, has been shown to be associated with species diversity. For example, butterfly abundance has been found to increase with heterogeneity. Land that is not cropped, such as fallow land, grass margins in the spaces between different fields, and strips of scrub along field boundaries increase heterogeneity and thus the biodiversity of a farm. Plants attract insects, which will attract certain species of birds, and those birds will attract their natural predators. The cover provided by non-cropped land allows species to move across

1073-650: The genetic diversity of trees. The term genetic diversity describes the differences in DNA sequence between individuals as distinct from variation caused by environmental influences. The unique genetic composition of an individual (its genotype ) will determine its performance (its phenotype ) at a particular site. Genetic diversity is needed to maintain the vitality of forests and to provide resilience to pests and diseases . Genetic diversity also ensures that forest trees can survive, adapt and evolve under changing environmental conditions. Furthermore, genetic diversity

1110-401: The greatest increase in the past 50 years. The loss of agricultural heterogeneity decreases local food security due to a loss in crop diversity, despite its accommodation of global food demands. Heterogeneity is essential in increasing species heterogeneity, which maintain stable ecological structures essential to providing ecosystem services. Of the features associated with species diversity

1147-402: The landscape. In Asian rice, one study showed crop diversification by growing flowering crops in strips beside rice fields could reduce pests so that insecticide spraying was reduced by 70%, yields increase by 5%, together resulting in an economic advantage of 7.5%. One of the issues facing biodiversity in areas of industrial agriculture is the loss of heterogeneity , described by the loss of

1184-442: The most important component of the biosphere , and forestry has emerged as a vital applied science , craft , and technology . A practitioner of forestry is known as a forester . Another common term is silviculturist. Silviculture is narrower than forestry, being concerned only with forest plants, but is often used synonymously with forestry. All people depend upon forests and their biodiversity, some more than others. Forestry

1221-440: The past centuries, forestry was regarded as a separate science. With the rise of ecology and environmental science , there has been a reordering in the applied sciences. In line with this view, forestry is a primary land-use science comparable with agriculture . Under these headings, the fundamentals behind the management of natural forests comes by way of natural ecology. Forests or tree plantations, those whose primary purpose

1258-457: The process of agro ecological restoration , as farm biodiversity is an aspect of agroecology . Biodiversity is the measure of biotic and abiotic diversity in an ecosystem, described by heterogeneity. The loss of biodiversity in agriculture has been an increasing issue since the global increase of food demands and success of popular crops. This loss of heterogeneity declines species biodiversity on agricultural lands. Biodiversity in agriculture

More than two-thirds of the total forest area affected was in Africa and South America. Insects, diseases and severe weather events damaged about 40 million hectares of forests in 2015, mainly in the temperate and boreal domains. Furthermore, the marginal populations of many tree species are facing new threats due to

1369-648: Was the New York State College of Forestry , established at Cornell University just a few weeks later, in September 1898. Early 19th century North American foresters went to Germany to study forestry. Some early German foresters also emigrated to North America. In South America the first forestry school was established in Brazil, in Viçosa , Minas Gerais , in 1962, and moved the next year to become
