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 […]
A grazing system based on one species (Brachiaria brizantha, representing 90% of sown grass in Amazoni) with Nelore zebu cattle, is adapted to marginal regions with little need for inputs, but income per hectare remains low. Integrated Crop and Livestock Systems in Amazonia can generate higher income per ha and stop deforestation. The system, which involves […]
In Vanuatu, farmers prefer to work numerous small fields in different locations and as a mechanism to cope with hurricane and pest damage. Shifting cultivation, a widespread cultivation system in the tropics, is also practiced and helps to maintain a high diversity of primary and subsidiary crops. 297 fields in 6 villages were measured and […]
In the communities around Lake Victoria, Kenya, diversified farms oscillate between activities in fishing, farming and livestock herding. These activities have become inextricably linked over many generations, with positive impacts upon household nutritional security.
In Northeastern Spain, artisanal Galician fisheries utilize a number of strategies in their fishing activities and livelihoods. These include: drawing upon a diversity of species fishing in a diversity of locations utilizing a diversity of fishing gear The seasonal income that fishing provides supplements the incomes of a range of people in other professions ranging […]
Family fishery operations are able to maintain flexibility through employing a number of different strategies. These include diversification of target species, gear types and fishing areas, buffering income uncertainties with supplier credits, diversifying into other types of employment or wage labor, and drawing upon community networks for cheap and unpaid assistance during times of need.
Following three years of insufficient rainfall in southern Ethiopia, the large scale die off of many livestock exacerbated local famine. Action for Development purchased 120 camels for hauling water, who liberated women from energy consuming water transport, and assist in ploughing the land when there is sufficient rainfall for planting. Camels can bring enough water […]
In Western Kenya, about 4000 farmers are enriching their farms with biomass from Tithonia, a wild sunflower that grows abundantly in hedgerows and along roadsides. Tithonia biomass contains high concentrations of Nitrogen, Phosphorus and Potassium, and decomposes rapidly. This has led to tremendous impacts on yields of maize and other high value crops such as […]
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 […]
