This study investigates soil productivity in the indigenous system (afub owondo) in Southern Cameroon in order to identify areas for improving soil and crop productivity, and food production. A challenge in most of Africa, is the continuous use of indigenous systems with slash-and-burn clearing like the afub owondo to meet food demand for the increasing population.

This publication reviews issues related to land degradation, with focus on problems of soil fertility management in sub-Saharan Africa. It highlights some successful experiences in the region, constraints and possible solutions specific to the major agro-ecological zones and the importance of the holistic and participatory approaches for soil productivity improvement. The need for action and collaborative efforts of all stakeholders, within the framework of ongoing initiatives, are emphasized. It is hoped that this document will contribute to increase awareness of senior specialists and policy-makers about the problems and alternative solutions towards enhanced and sustained soil productivity.

Scientific Essay from the year 2018 in the subject Agrarian Studies, grade: 5.25, University of Yaoundé I, language: English, abstract: Investigations were conducted to assess farmers’ perceptions of the effects of associated tree species on soil fertility status under cocoa-based systems in the Evodoula district one of the oldest cocoa producing basin of southern Cameroon characterized by a high population density and land use intensity. Farmers were asked to rank, based on their knowledge of the fertilizing patterns of associated species, ten trees species with the most positive effects on soil fertility. The ranking was tested with respect to the amount of litter fall and the quantity of minerals released (N, P, K, Ca and Mg) as factors affecting the nutrient recycling process. In decreasing order of importance, the top ten species identified were Milicia excelsa, Alstonia boonei, Terminalia superba, Irvingia gabonensis, Ceiba pentandra, Ficus mucoso, Musanga cecropoides, Coula edulis, Eribroma oblungum and Zanthoxylum heitzi. The mean litter fall ranged from 19.03 to 0.52 kg/ha and N was the main nutrient in the leaf litter of the different tree species with its concentration varying from 29.81 to 53.56 g/kg and a mean of 42.31 g/kg. P was present in very low concentrations (from 0.4 to 1.96 g/kg) while K varied widely from 0.76 to 6.82 g/kg. Mg was quantitatively the second element in the leaf litter, with values ranging from 8.84 to 37.29 g/kg. A strong correlation (P

Indigenous soil and water conservation practices are rarely acknowledged in the design of conventional development projects. Instead, the history of soil and water conservation in Africa has been one of imposing external solutions without regard for local practice. There is a remarkably diverse range of locally developed and adapted technologies for the conservation of water and soil, well suited to their particular site and socio-economic conditions. But such measures have been ignored, and sometimes even overturned, by external solutions. Sustaining the Soil documents farmers' practices, exploring the origins and adaptations carried out by farmers over generations, in response to changing circumstances. Through a comparative analysis of conservation measures - from the humid zones of West Africa to the arid lands of the Sudan, from rock terraces in Morocco to the grass strips of Swaziland - the book explores the various factors that influence adoption and adaptation; farmers' perceptions of conservation needs; and the institutional and policy settings most favorable to more effective land husbandry. For the first time on an Africa-wide scale, this book shows that indigenous techniques work, and are being used successfully to conserve and harvest soil and water. These insights combine to suggest new ways forward for governments and agencies attempting to support sustainable land management in Africa, involving a fusion of traditional and modern approaches, which makes the most of both the new and the old.
