Soil Fertility Decline in the Tropics available in PDF, EPUB and Kindle. * Wide coverage of soils and perennial cropping systems in the tropics * Synthesis of decades of research * Challenges assumptions on the benefits of plantations for soil fertility It is generally assumed that soil fertility decline is widespread in the tropics and that this is largely associated with annual cropping and subsistence farming. In contrast, perennial plant cover (as in plantation agriculture) provides better protection for the soil. This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics. These include perennial crops, annual crops and forest plantations. Two case studies, on sisal plantations in Tanzania and sugar cane in Papua New Guinea, are presented for detailed analysis. The author demonstrates that soil fertility decline is also a problem on plantations.

Economics and Ecology of Diversification available in PDF, EPUB and Kindle. The monoculture systems that have been encouraged by governments since the 1960s have led to major socio-economic and environmental crises. Now the diversification of tree crop systems is advancing throughout the tropics. Why and when does diversification take place? What categories of farmers diversify? What obstacles do they have to overcome, and how do public and private policies interfere in this process? How do land use systems and landscapes evolve as a result of this diversification? According to the authors of this volume, diversification is certainly a response to market risks, but also to the depletion of environmental resources. Ecological changes such as declining soil fertility and increasing pressure from pests, diseases and weeds intensify at the end of monoculture cycles, driving crop change and diversification of farming systems. Through 15 case studies from Africa, Latin America, Asia and the Pacific, the authors provide us with in-depth insights into the economy and ecology of family agriculture and its recent developments.
