The river basins were all affected to varying degrees by subsistence farming which is the dominant land use in Malawi. Sediment and nutrient (C, N, P, Si) concentrations, loads, and yields were sensitive to the degree of agricultural land use in the basins. Lowest sediment concentrations, ...
The study examines the combination of factors (social, economic, political and environmental) that either stimulate or discourage on-farm tree planting on smallholdings in Malawi, highlighting how woodland resource use changes over a gradient of land use intensity. This study gives a detailed insight...
摘要: The literature on deforestation in Malawi points to a number of causes, including high population in relation to available land, poverty, market and policy failures, drought, and the severity of structural adjustment policies.关键词:

This paper reviews the research on land use change and its corresponding ecological responses. Patterns of land use changes in spatio-temporal level are pr
suitability of specific malaria transmitting mosquitoes and subsequent malaria transmission15. Frontier malaria may also occur, where a change in spatial or temporal malaria risk of previously undeveloped areas occurs as a result of large-scale land-use transformations due to agriculture15,16,17,18,19...

Farmers' socioeconomic characteristics such as such as experience in agriculture, participation in off-farm activity, availability of farmland, organization membership, access to credit, contact with extension and household size have significant but differential effects on the choices of land use ...
Remote sensing techniques are evaluated for their use in land cover and land use mapping. Catchment monitoring and management requires detailed and up to date information about the surface runoff, cover and use. Remote sensing as a data gathering technique can rapidly deliver very detailed studies ...
The Nasia catchment is the reservoir with significant surface water resources in Northern Ghana and home to numerous subsistence farmers engaged in rainfed and dry season irrigation farming. Yet, there is little understanding of the hydro-climatic and land use/cover conditions of this basin. This st...
