    Although advances in remote sensing have enhanced mapping and monitoring of irrigated areas, producing accurate cropping information through satellite image classification remains elusive due to the complexity of landscapes, changes in reflectance of different land-covers, the remote sensing data selected, and image processing methods used, among others. This study extracted agricultural fields in the former homelands of Venda and Gazankulu in Limpopo Province, South Africa.

    The research on inventory of some gully erosion sites in central Cross River State, Southeastern Nigeria was carried out in 2002. The objectives of the research were to identify spectacular gullies in the area (Yakkur, Obubra and Ikom Local Government Areas); determine the dimensions, causes and the land use affected.Gullies identified in Yakurr were located at Njelekoko, Ugbekuma, Ajere and Lekpankom. In Obubra area they were at Ofukpa and Etapeh, while in Ikom they were located at Water Board road, Cameroon street and Abakpa.

    Resource-poor farmers in developing nations cultivate marginal lands, thereby exacerbating the problem of soil degradation through poor plant growth and ground coverage. An assessment of ground cover under such a practice will provide a guideline for soil conservation. Ground cover by leguminous cover crops (e.g., Mucuna pruriens, Pueraria phaseoloides and Vigna unguiculata), associated with yam, maize and rice was measured in three different experiments in southwestern Nigeria using beaded-string method while leaf area was measured using a flat-bed scanner.

    Rwanda

    Rwanda is currently in transition from a period of emergency to one of development following the 1994 war and genocide. Before the tragic events of 1994, the Agricultural Statistics Division (DSA) of the Ministry of Agriculture, Animal Resources and Forestry (MINAGRI) maintained a comprehensive database of agricultural statistics. The DSA was responsible for providing information on agricultural policy based on annual surveys of rural households. These surveys, which were interrupted in 1994 were resumed in 1999 by the Food Security Research Project (FSRP) and the DSA of MINAGRI.

    It is well known that land-use changes influence the hydrological cycle and that those changes in the hydrological cycle influence land use. The sophisticated spatial dynamic planning tools that have been developed in the last decades to support policy makers in the decision making process do not take into account the mutual feedbacks between land use and hydrology.
