Outcomes
, ,

Over 5 years of participatory on-farm research, market access, profitability, farming systems productivity and economic sustainability were compared on 100 small-scale farms in Central Cameroon. Integration technology based on the use of agricultural by-products as fishpond inputs was the driver for intensification. Over all farms, fishpond productivity increased from 498 kg to 1609 kg fish/ha […]

In the 1990’s, the Rice-Wheat Consortium was launched to address a plateau in crop productivity, loss of soil organic matter and receding groundwater tables. Rice-wheat farming systems were developed, planting wheat after rice using a tractor-drawn seed drill to seed directly into unploughed fields with a single pass. Zero tillage wheat permits earlier planting, helps […]

  Aquaculture is the fastest growing food producing sub-sector in the world, particularly in developing countries, with total aquaculture production nearly tripling between 1987 and 1999. In Asia, widespread adoption of aquaculture on traditional farms have demonstrated improved productivity, and additional sources of income and nutrition for the household. Aquaculture contributes to food and nutritional […]

Agroforestry can provide alternatives to slash and burn agriculture at tropical forest margins in subhumid tropical Africa.  The trade-offs between carbon sequestration and farmer profitability may provide additional options to policy makers. Agroforestry practices can sequester 57Mg C per ha, three times that of croplands or grasslands are able to do. Soil nutrient capital is being […]

Legumes Improve Maize Yields and Income in Semi-Arid Kenya

Outcomes
,

A study was conducted by ICRAF to evaluate the effect of annual and perennial legumes on soil fertility, cereal yields and economic returns. The study evaluated six cropping systems: (1) continuous sole maize, (2) maize rotated with short-duration legume, cowpea (Vigna unguiculata L. Walp.), (3) maize rotated with long-duration legume, pigeonpea (Cajanus cajan L. Millsp.), (4) […]

In rain-limited regions of Burkina Faso, improved water harvesting and soil erosion control using contour stone bunding is shown to increase grain yields by 41% in low rainfall regions of Burkina Faso. Yield increases in food crops help foodbuying farm households import substitute in food consumption, reduce livestock production, and increase seasonal migration which is […]

An indigenous Incan system of raised fields evolved in the high plains of the Peruvian Andes about 3000 years ago,. The platforms of soil were surrounded by ditches filled with water, which were able to produce bumper crops even despite the exposure to floods, droughts and frosts at high alititudes.  Terraces minimize risk to drought […]
