“…Wood et al (2004) found that agricultural extensification in Velingara, a tropical dry woodland area in south-central Senegal, poses a significant threat to both upland woodlands and riparian forests. Furthermore, lack of clarity about the land tenure and land allocation powers of administrative units led to increased clearing of forests and other unsuitable land management techniques (Wood, 2002).…”

This study compares the results of two nationwide land degradation assessments for Senegal. The first approach is based on expert judgments, the second on trend analyses of Rainfall Use Efficiency (RUE). The comparison yields some interpretable results for extreme negative RUE slope values with maximum degrees of land degradation as indicated by experts, yet, overall, the correlation between both approaches proves to be low and without clear sign. As RUE trend analysis suffers from several inherent methodological problems and expert judgments are found to be consistent we consider expert opinions as the preferable option for a nation-wide land degradation assessment in Senegal. Yet, we argue that methodological improvements would increase the explanatory power of the expert approach and consolidate its position in a policy making framework.

“…Land-use/cover change and population dynamics are central in understanding soil fertility dynamics in the sub-Saharan Africa [1,2]. Although parent material, climate, geological, and management history are viewed as the drivers of soil properties at regional and continental scales [3,4], landscape position and land-use/cover are key factors influencing soil properties under a hillslope and microcatchment scale [5,6].…”

This study determined the change and distribution of land-uses/covers along the landscape, and evaluated the nutrient status of the top soil layer in the Lake Kivu Pilot Learning Site (LKPLS) benchmarked micro-catchments. Soil physical and chemical properties were quantified using triplicate soil samples collected from each land-use/cover at two depths (0-15 and 15-30 cm) in three LK PLS Learning Innovation Platform (IP) sites (Bufundi in Uganda, Mupfuni-Shanga in D.R. Congo, Gataraga in Rwanda). Small scale agriculture has increased in all the benchmarked micro-catchments at the expense of other land-uses/covers. In the settlement areas land-use/cover distribution along the landscape varied across sites and countries; the major one being eucalyptus woodlots, wetland, and perennials and annuals crops in Bufundi; annuals and perennials crops in Mupfuni-Shanga; and annuals crops in Gataraga. Perennial crops tended to occur at the footslope and valley bottoms, while the annuals occurred at the upper backslopes and summits. Available P and K were relatively higher and C/N ratio (7.28) was the lowest in Mupfuni Shanga. Annual crops had the lowest available P and N across site ( < 0.05). The key nutrients N, P and K were below the critical values for plant growth for Bufundi.

“…Population growth and pressure in the study area is as a result of increased migration of farmers and fisher folks from adjoining districts in the Volta region and other parts of the country. These movements are attributable to the declining soil fertility, decreased precipitation and poverty in the source districts and the perceived potential for agriculture in the destination (Wood et al, 2004).…”

“…This level of change is commensurate with the level of change in the Agriculture class from the landcover maps for the period. Population size and density, therefore, have a very strong correlation of 0.97 with agriculture, and this explains the fact that increases in the level of agriculture is attributable to rapid population growth (Wood et al, 2004;Codjoe, 2005b). …”
