Agrarian development in Africa http://trophort.com/research/000/015/... The problems of 'development' techniques in agricultural production are apparent in many agriecological regions of Africa. Some approaches tend to develop small-scale, subsistence farming systems whereas others promote large-scale mechanized farms, group farms and other mechanized schemes. The latter have a high cost value out of proportion to their benefits for a developing economy in the short run, however, for combating the projected 'hunger crisis' worldwide, they may prove to be the better alternative in the long run.
Adequate least-cost diets for third-world country populations http://trophort.com/research/000/014/... The diet of large sectors of the population of third-world countries is insufficient. This is particularly true for pregnant and lactating women and for people conducting hard manual labor. Such diets are frequently deficient in high-quality protein, vitamins A and B2. For meeting nutritional requirements, rice and bread may be replaced by pasta or other processed cereals or flours depending on availability. Some meat should be included in all diets although amounts will remain small due to high cost.
Causes of world shortages of key commodities http://olericulture.org/research/000/015/... In the past, most economic indicators changed slowly and continuously and economists could therefore explain and predict them. This is in the process of dramatic change. The recent price explosions in rice were not only triggered by doubling of costs for major inputs including fertilizers and pesticides but also by general shortages on the world market caused by substantial decreases in exports. The latter shortages are results of a widening gap between domestic demand and supply in many countries ncluding India and China. Developing countries such as Haiti with no substantial domestic production but ever increasing population simply can no longer afford to finance purchases on this scale and the developed countries cannot give that amount away as aid.
Adaptation of cattle to tropical environments http://trophort.com/research/000/013/... Indigenous tropical cattle is usually better adapted to heat. In contrast, imported breeds require more shade, thus jeopardizing grazing time. Their food intake is reduced in the heat and they carry this too far. Indigenous cattle can reduce their metabolic rate and their water requirement to half that of imported breeds and selective grazing as well as stopping feeding and metabolising fat enables them to survive in the dry season.
Sustainable and productive forest management in Trinidad http://pomology.org/research/000/006/... Trinidad sustainable yet productive natural management of forest reserves is internationally reputed. This is due to the co-existance of science and management in forest administration, practices and ecology. While the scheme is based upon statistical probability, management practices are adapted to variations in ecological, socio-economic and political factors.
Biomass production of forests in tropical Africa http://trophort.com/research/000/012/... Litter fall is greatest during the end of the dry season with a smaller peak between the first and second rainfall of the rainy season. Annual litterfall is about 10 t dry matter/ha/year and total biomass production 20-25 t dry matter/ha/yr.
Global warming: CO2 and temperature accelerates plant growth http://olericulture.org/research/000/014/... The greenhouse effect, ie, raised temperature plus elevated carbon dioxide (CO2), accelerates plant growth by 30-40%. This extra biomass potential requires extra water and particularly nitrogen which is supplied by the forecasted increases in precipitation and nitrogen deposition.
Strategies for sucessful rural development http://trophort.com/research/000/011/... A combination of technically advanced yet labour-intensive agriculture, based upon organized farmers-groups composed of individual small-scale farms offers the best prospect for developing a self-supporting agriculture which is the backbone for self-sustaining rural development.
Pink Lady http://pomology.org/research/000/005/... "Pink Lady" is an apple cultivar originating from a cross between "Lady Williams" and "Golden Delicious". Pink Lady fruits are ca. 75 cm in diameter with 40-70% of the surface pink in color.
Impact of the Green Revolution on the development of agriculture in India http://trophort.com/research/000/010/... The farmers in a majority of districts in India benefited from the technologies introduced by the Green Revolution whereas those in other districts did not benefit. Such imbalances in regional development of the agricultural economy must be prevented in future.
Biofuel: castor bean oil http://olericulture.org/research/000/013/... Castor oil is traditionally known for the medicinal use of its main component, Ricinoleic acid, which excerts anti-flammatory effects. It, however, has numerous other applications in transportation, cosmetics and manufacturing industries. Leading producers of castor oil are India, China and Brazil who account for 90% of the area and production of castor oil, which is now increasingly traded in commodity exchanges.
Forecasting regional development of agricultural structure http://trophort.com/research/000/009/... Possible development of farm structure in particular regions depends on many factors including agricultural policy, changes in production conditions, structure of the agricultural enterprises and the interdependences between farms.
