Subsistence Farming
Subsistence agriculture occurs when farmers grow crops on smallholdings to meet the needs of themselves and their families. Subsistence agriculturalists target farm output for survival and for mostly local requirements. Planting decisions occur principally with an eye toward what the family will need during the coming year, and only secondarily toward market prices. Tony Waters, a professor of sociology, defines "subsistence peasants" as "people who grow what they eat, build their own houses, and live without regularly making purchases in the marketplace". Despite the self-sufficiency in subsistence farming, most subsistence farmers also participate in trade to some degree. Although their amount of trade as measured in cash is less than that of consumers in countries with modern complex markets, they use these markets mainly to obtain goods, not to generate income for food; these goods are typically not necessary for survival and may include sugar, iron roofing-sheets, bicyc ...

Bakweri Cocoyam Farmer From Cameroon
The Bakweri (or Kwe) are a Bantu peoples, Bantu ethnic group of the Republic of Cameroon. They are closely related to Cameroon's coastal peoples (the The Sawa peoples of Cameroon, Sawa), particularly the Duala people, Duala and Isubu. Early survey discussion of these topics may be found in Ardener 1956 and Dugast 1949 History Early population movements The Bakweri likely migrated to their present home east of the mountain in the mid-18th century. From the foothills, they gradually spread to the coast, and up the Mungo River, Cameroon, Mungo River and the various creeks that empty into it. In the process, they founded numerous villages, usually when individual families groups split off.Fanso 50. A rival Bakweri tradition says they descend from Mokuri a Mbedi, Mokuri or Mokule, a brother of the Duala's forebear Ewale a Mbedi, Ewale, who migrated to the Mount Cameroon area for hunting. In addition, a few isolated villages, such as Maumu and Bojongo, claim some alternate descent and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharecropping
Sharecropping is a legal arrangement in which a landowner allows a tenant (sharecropper) to use the land in return for a share of the crops produced on that land. Sharecropping is not to be conflated with tenant farming, providing the tenant a higher economic and social status. Sharecropping has a long history and there are a wide range of different situations and types of agreements that have used a form of the system. Some are governed by tradition, and others by law. The France, French ''métayage'', the Catalonia, Catalan ''masoveria'', the Castile (historical region), Castilian ''mediero'', the Slavs, Slavic ''połownictwo'' and ''izdolshchina, the Italy, Italian mezzadria'', and the Islamic economics, Islamic system of ''muzara‘a'' (المزارعة), are examples of legal systems that have supported sharecropping. Overview Under a sharecropping system, landowners provided a share of land to be worked by the sharecropper, and usually provided other necessities such as h ...

Soil Erosion
Soil erosion is the denudation or wearing away of the Topsoil, upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, Atmosphere of Earth, air (wind), plants, and animals (including humans). In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, Aeolian erosion, wind (aeolian) erosion, Zoogenic erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from Agricultural land, farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. Soil erosion could also cause sinkholes. Human activities have increased by 10–50 times the rate at which erosion is occurring world-wide. Exc ...

Deforestation
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage. The direct cause of most deforestation is agriculture by far. More than ...

Biomass
Biomass is a term used in several contexts: in the context of ecology it means living organisms, and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants, from plants and algae, from plants and animals. The vast majority of biomass used for bioenergy does come from plants and fecal matter. Bioenergy is a type of renewable energy that the bioenergy industry claims has the potential to assist with climate change mitigation. Uses in different contexts Ecology * Biomass (ecology), the mass of living biological organisms in a given area or ecosystem at a given time. This can be the biomass of particular species or the biomass of a particular community or habitat. Energy * Biomass (energy), biomass used for energy production or in other words: biological mass used as a renewable energy source (usually produced through agriculture, forestry or ...

Soil Fertility
Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.Bodenfruchtbarkeit Retrieved on 2015-11-09. It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time. A fertile soil has the following properties: * The ability to supply essential plant nutrients and water in adequate amounts and proportions for plant growth and reproduction; and * The absence of toxic substances which may inhibit plant growth e. ...

Heat Tolerance
Plant breeding is process of development of new cultivars. Plant breeding involves development of varieties for different environmental conditions – some of them are not favorable. Among them, heat stress is one of such factor that reduces the production and quality significantly. So breeding against heat is a very important criterion for breeding for current as well as future environments produced by global climate change (e.g. global warming). Breeding for heat stress tolerance in plants Heat stress due to increased temperature is a very important problem globally. Occasional or prolonged high temperatures cause different morpho-anatomical, physiological and biochemical changes in plants. The ultimate effect is on plant growth as well as development and reduced yield and quality. Breeding for heat stress tolerance can be mitigated by breeding plant varieties that have improved levels of thermo-tolerance using different conventional or advanced genetic tools. Marker assist ...

Climate Change
Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is Scientific consensus on climate change, driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, Deforestation and climate change, deforestation, and some Greenhouse gas emissions from agriculture, agricultural and Environmental impact of concrete, industrial practices release greenhouse gases. These gases greenhouse effect, absorb some of the heat that the Earth Thermal radiation, radiates after it warms from sunlight, warming the lower atmosphere.

Tropical Climate
Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A. Tropical climates are defined by a monthly average temperature of or higher in the coolest month, featuring hot temperatures and high humidity all year-round. Annual precipitation is often abundant in tropical climates, and shows a seasonal rhythm but may have seasonal dryness to varying degrees. There are normally only two seasons in tropical climates, a wet (rainy/monsoon) season and a dry season. The annual temperature range in tropical climates is normally very small. Sunlight is intense in these climates. There are three basic types of tropical climates within the tropical climate group: tropical rainforest climate (Af), tropical monsoon climate (Am) and Tropical savanna climate, tropical savanna or tropical wet and dry climate (Aw for dry winters, and As for dry summers), which are classified and distinguished by the precipitation levels of the ...

Developing Countries
A developing country is a sovereign state with a less-developed Secondary sector of the economy, industrial base and a lower Human Development Index (HDI) relative to developed countries. However, this definition is not universally agreed upon. There is also no clear agreement on which countries fit this category. The terms low-and middle-income country (LMIC) and newly emerging economy (NEE) are often used interchangeably but they refer only to the economy of the countries. The World Bank classifies the world's economies into four groups, based on gross national income per capita: high-, upper-middle-, lower-middle-, and low-income countries. Least developed countries, landlocked developing countries, and Small Island Developing States, small island developing states are all sub-groupings of developing countries. Countries on the other end of the spectrum are usually referred to as World Bank high-income economy, high-income countries or Developed country, developed countries. ...

Farmers' Suicides In India
Farmers' suicides in India refers to the event of farmers dying by suicide in India since the 1970s, due to their inability to repay loans mostly taken from private landlords and banks. India being an agrarian country with around 70% of its rural population depending directly or indirectly upon agriculture, the sector had a 15% share in the economy of India in 2023, and according to National Sample Survey Office (India), NSSO, around 45.5% of country's labor force was associated with agriculture in 2022. Activists and scholars have offered several conflicting reasons for farmer suicides, such as anti-farmer laws, high debt burdens, poor government policies, corruption in subsidies, crop failure, mental health, personal issues and family problems. The National Crime Records Bureau data shows that while 296,438 farmers had died by suicide between 1995 and 2014, in the nine years between 2014 and 2022, the number stood at 100,474. In 2022, a total of 11,290 persons involved in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
