    Zambia

    The Government of Zambia is embarking on an ambitious program of legal and administrative reforms in land policy. Although the need to liberalize the land market is universally shared, the ideas on how to accomplish this transformation are not. Two decades of underinvestment in field research have resulted in the present situation of micro-level data on land tenure and farm-level production, consumption, and resource management inadequate to guide policy decisions.

    The cultivation of calopo, Calopogonium mucunoides, as a promising forage legume for the lowland tropics, was hindered by its susceptibility to a severe yellow mosaic disease observed in the Eastern Plains of Colombia. An isometric virus ca. 28 nm in diameter was observed by electron microscopy in leaf extracts and purified preparations, and in phloem cells of systemically infected calopo plants. The virus was transmitted by mechanical means and by the chrysomelid beetle Diabrotica balteata. The host range of the virus was restricted to the legumes Phaseolus vulgaris, Vigna unguiculala, V.

    This project was set up to investigate the level of accuracy which can be expected for slope and altitude values derived from low-cost Digital Elevation Models (DEMs). Eight gridded DEMs were generated from digitized contour maps at a range of scales:1:10,000 1:25,000 1:100,000 1:200,000 - and using a range of contour intervals 25m, 50m and 100m. A Control DEM was then produced using large scale aerial photographs (1:28,000) which were registered for auto-extraction of z-values using Helava software and accuracy tested using 91 differentially measured GPS ground control points.
