The economy of Namibia has a modern market sector, which produces most of the country's wealth, and a traditional subsistence sector. Although the majority of the population engages in subsistence agriculture and herding, Namibia has more than 200,000 skilled workers and a considerable number of well-trained professionals and managerials.
Subsistence agriculture occurs when farmers grow crops to meet the needs of themselves and their families on smallholdings. 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".
A cash crop, also called profit crop, is an agricultural crop which is grown to sell for profit. It is typically purchased by parties separate from a farm. The term is used to differentiate marketed crops from staple crop in subsistence agriculture, which are those fed to the producer's own livestock or grown as food for the producer's family.
Fodder, also called provender, is any agricultural foodstuff used specifically to feed domesticated livestock, such as cattle, rabbits, sheep, horses, chickens and pigs. "Fodder" refers particularly to food given to the animals, rather than that which they forage for themselves. Fodder includes hay, straw, silage, compressed and pelleted feeds, oils and mixed rations, and sprouted grains and legumes. Most animal feed is from plants, but some manufacturers add ingredients to processed feeds that are of animal origin.
There are different systems of feeding cattle in animal husbandry. For pastured animals, grass is usually the forage that composes the majority of their diet. In turn, this grass-fed approach is known for producing meat with distinct flavor profiles. Cattle reared in feedlots are fed hay supplemented with grain, soy and other ingredients to increase the energy density of the feed. The debate is whether cattle should be raised on fodder primarily composed of grass or a concentrate. The issue is complicated by the political interests and confusion between labels such as "free range", "organic", or "natural". Cattle raised on a primarily foraged diet are termed grass-fed or pasture-raised; for example meat or milk may be called grass-fed beef or pasture-raised dairy. The term "pasture-raised" can lead to confusion with the term "free range", which does not describe exactly what the animals eat.
Agroforestry is a land use management system that integrates trees with crops or pasture. It combines agricultural and forestry technologies. As a polyculture system, an agroforestry system can produce timber and wood products, fruits, nuts, other edible plant products, edible mushrooms, medicinal plants, ornamental plants, animals and animal products, and other products from both domesticated and wild species.
Agriculture's share of GDP has declined in recent years, falling from 42% in 1989, to 26% in 1999. In 2023, agriculture and forestry accounted for about 12% of Vietnam's gross domestic product (GDP). However, agricultural employment was much higher than agriculture's share of GDP; in 2005, approximately 60 percent of the employed labor force was engaged in agriculture, forestry, and fishing. Agricultural products accounted for 30 percent of exports in 2005. The relaxation of the state monopoly on rice exports transformed the country into the world's second or third largest rice exporter. Other cash crops are coffee, cotton, peanuts, rubber, sugarcane, and tea.
Animal feed is food given to domestic animals, especially livestock, in the course of animal husbandry. There are two basic types: fodder and forage. Used alone, the word feed more often refers to fodder. Animal feed is an important input to animal agriculture, and is frequently the main cost of the raising or keeping of animals. Farms typically try to reduce cost for this food, by growing their own, grazing animals, or supplementing expensive feeds with substitutes, such as food waste like spent grain from beer brewing.
Agriculture in Ghana consists of a variety of agricultural products and is an established economic sector, providing employment on a formal and informal basis. It is represented by the Ministry of Food and Agriculture. Ghana produces a variety of crops in various climatic zones which range from dry savanna to wet forest which run in east–west bands across Ghana. Agricultural crops, including yams, grains, cocoa, oil palms, kola nuts, and timber, form the base of agriculture in Ghana's economy. In 2013 agriculture employed 53.6% of the total labor force in Ghana.
Agriculture in Ethiopia is the foundation of the country's economy, accounting for half of gross domestic product (GDP), 83.9% of exports, and 80% of total employment.
Agriculture employs the majority of Madagascar's population. Mainly involving smallholders, agriculture has seen different levels of state organisation, shifting from state control to a liberalized sector.
Located in the Sahelian and Saharan zones, Mauritania has one of the poorest agricultural bases in West Africa. Most important to the rural economy has been the livestock subsector. Between 1975 and 1980, herding engaged up to 70 percent of the population, and sedentary farmers constituted about 20 percent of the population. The vast majority of the population lived in the southern one-third of the country, where rainfall levels were high enough to sustain cattle herding. Farming was restricted to the narrow band along the Senegal River where rainfall of up to 600 millimeters per year and annual river flooding sustained crop production as well as large cattle herds. In the dry northern two-thirds of the country, herding was limited to widely scattered pastoral groups that raised camels, sheep, and goats, and farming was restricted to date palms and minuscule plots around oases.
Agriculture in Sudan plays an important role in that country's economy. Agriculture and livestock raising are the main sources of livelihood for most of the Sudanese population. It was estimated that, as of 2011, 80 percent of the labor force were employed in that sector, including 84 percent of the women and 64 percent of the men.
The role of agriculture in the Bolivian economy in the late 1980s expanded as the collapse of the tin industry forced the country to diversify its productive and export base. Agricultural production as a share of GDP was approximately 23 percent in 1987, compared with 30 percent in 1960 and a low of just under 17 percent in 1979. The recession of the 1980s, along with unfavorable weather conditions, particularly droughts and floods, hampered output. Agriculture employed about 46 percent of the country's labor force in 1987. Most production, with the exception of coca, focused on the domestic market and self-sufficiency in food. Agricultural exports accounted for only about 15 percent of total exports in the late 1980s, depending on weather conditions and commodity prices for agricultural goods, hydrocarbons, and minerals.
Agriculture in South Africa contributes around 5% of formal employment, relatively low compared to other parts of Africa and the number is still decreasing, as well as providing work for casual laborers and contributing around 2.6 percent of GDP for the nation. Due to the aridity of the land, only 13.5 percent can be used for crop production, and only 3 percent is considered high potential land.
Agriculture in Sweden differs by region. This is due to different soils and different climate zones, with many parts of the country being more suitable to forestry. It makes more economic sense to dedicate land to forestry than agriculture in the northern and mountainous parts of the country.
Agriculture in the Republic of the Congo is mostly at the subsistence level. Self-sufficiency in food production is yet to be achieved. Cassava (manioc) is the basic food crop everywhere in the country except in the southern region, where bananas and plantains are prevalent. Among the cash crops, the most important are sugarcane and tobacco, though palm kernels, cacao, and coffee are also cultivated to some extent. The main consumption crops are bananas, manioc, peanuts, plantains, sugarcane, and yams. Subsistence agriculture is the country's most significant employer, and it is one of the three most important economic sectors. With the government's efforts since 1987, agricultural production has increased due to "abolishing state marketing boards, freeing prices, launching new agricultural credit institutions and closing down most state farms". The Niari Valley in the south is a notable agricultural area.
Woody plant encroachment is a natural phenomenon characterised by the increase in density of woody plants, bushes and shrubs, at the expense of the herbaceous layer, grasses and forbs. It predominantly occurs in grasslands, savannas and woodlands and can cause regime shifts from open grasslands and savannas to closed woodlands. The term bush encroachment refers to the expansion of native plants and not the spread of alien invasive species. It is thus defined by plant density, not species. Woody encroachment is often considered interpreted as a symptom of land degradation. The phenomenon is observed across different ecosystems and with different characteristics and intensities globally.
Forestry in Sudan includes both traditional gatherers of firewood and producers of charcoal—the main sources of fuel for homes and some industries—and a modern timber and sawmilling industry, the latter government-owned. Forestry activities started with Condominium rule in 1899, when the government commissioned an Indian forester to produce a comprehensive report on the state of forests in the country. As a result, the Woods and Forests Ordinance was published in 1901, and the Department of Woodlands and Forests established. The First Forest Act replaced the ordinance in 1908, and legislation continued to evolve over the next century.
