Land Degradation and Desertification
This book is organized into two sections. The first section covers three major aspects, viz., an understanding of patterns of land degradation and desertification for developing mitigation strategies, land-atmosphere interaction from response of land cover to climate change effects of Karst rocky desertification. The last section dwells on the relationship between soil degradation and crop production and an examination on how land degradation impacts the quality of soil in communal rangelands.

In the first section of this book on soil erosion, an introduction to the soil erosion problem is presented. In the first part of the second section, rainfall erosivity is estimated on the basis of pluviograph records and cumulative rainfall depths by means of empirical equations and machine learning methods. In the second part of the second section, a physically-based, hydrodynamic, finite element model is described for the computation of surface runoff and channel flows.

Soil Fertility book presents nine chapters written by renowned soil fertility experts from Africa, Asia and South America. The book is divided into two sections. Section 1, Biological Processes and Integration of Inorganic and Organic Fertilizers for Soil Fertility Improvement, examines biological processes that can enhance the soil fertility. The second section, Improving Fertilizer Recommendation and Efficiency, looks at the state-of-the-art in leaf sampling and analysis.
