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".
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.
Agriculture in Mongolia constitutes over 10% of Mongolia's annual gross domestic product and employs one-third of the labor force. However, the high altitude, extreme fluctuation in temperature, long winters, and low precipitation provides limited potential for agricultural development. The growing season is only 95 – 110 days. Because of Mongolia's harsh climate, it is unsuited to most cultivation.
Farmer-managed natural regeneration (FMNR) is a low-cost, sustainable land restoration technique used to combat poverty and hunger amongst poor subsistence farmers in developing countries by increasing food and timber production, and resilience to climate extremes. It involves the systematic regeneration and management of trees and shrubs from tree stumps, roots and seeds. FMNR was developed by the Australian agricultural economist Tony Rinaudo in the 1980s in West Africa. The background and development are described in Rinaudo's book The Forest Underground.
Forest farming is the cultivation of high-value specialty crops under a forest canopy that is intentionally modified or maintained to provide shade levels and habitat that favor growth and enhance production levels. Forest farming encompasses a range of cultivated systems from introducing plants into the understory of a timber stand to modifying forest stands to enhance the marketability and sustainable production of existing plants.
Mixed farming is a type of farming which involves both the growing of crops and the raising of livestock. Such agriculture occurs across Asia and in countries such as India, Malaysia, Indonesia, Afghanistan, South Africa, China, Central Europe, Canada, and Russia. Though at first it mainly served domestic consumption, countries such as the United States and Japan now use it for commercial purposes.
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.
In 2020, approximately 80% of Chad's labor force was employed in the agricultural sector. This sector of the economy accounts for 52.3% of the GDP, as of 2017. With the exception of cotton production, some small-scale sugar cane production, and a portion of the peanut crop, Chad's agriculture consists of subsistence food production.
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.
The southeast Asian country of Laos, with a landmass of 23.68 million hectares, has at least 5 million hectares of land suitable for cultivation. Seventeen percent of this land area is actually cultivated, less than 4 percent of the total area.
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 is the primary economic activity of a majority of Niger's 17 million citizens.
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.
Agriculture in Mexico has been an important sector of the country’s economy historically and politically even though it now accounts for a very small percentage of Mexico’s GDP. Mexico is one of the cradles of agriculture with the Mesoamericans developing domesticated plants such as maize, beans, tomatoes, squash, cotton, vanilla, avocados, cacao, various kinds of spices, and more. Domestic turkeys and Muscovy ducks were the only domesticated fowl in the pre-Hispanic period and small dogs were raised for food. There were no large domesticated animals.
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 biome 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. Bush encroachment is often considered an ecological regime shift and can be a symptom of land degradation. The phenomenon is observed across different ecosystems and with different characteristics and intensities globally.
