As part of its efforts to improve fertilizer use and efficiency in West Africa, and following the recent adoption of the West African fertilizer recommendation action plan (RAP) by ECOWAS, this volume focuses on IFDC's technical lead with key partner institutions and experts to build on previous and current fertilizer recommendations for various crops and countries in West Africa for wider uptake by public policy makers and fertilizer industry actors.

While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management.

This book summarizes studies on climate and ecosystem change adaptation and resilience in Africa (CECAR-Africa), a collaboration with the goal of creating an integrated resilience enhancement strategy as a potential model for semi-arid regions across Sub-Saharan Africa by combining climate change and ecosystem change research. The case studies were conducted at multiple scales – local, national, and regional – and incorporate the natural sciences, social sciences and engineering in a transdisciplinary manner while also integrating the needs of local communities. The book chiefly addresses three thematic areas, namely: Forecast and assessment of climate change impacts on agro-ecosystems; Risk assessment of extreme weather hazards and development of adaptive resource management methods; and Implementing capacity development programs for local leaders and practitioners. The collaborative nature of the project and the use of various quantitative and qualitative research technique s and methods – such as field surveys, questionnaires, focus group discussions, land use and cover change analysis, and climate downscaled modeling – make the book truly unique. Especially at a time when both long-term climate change and short-term extreme weather events such as droughts and floods are worsening, this book offers potential approaches to developing an integrated framework for assessing the local ability to cope with floods and droughts, and for enhancing the resilience of farming communities in developing countries, which are the most vulnerable to these changes and extreme weather events. As such, it will be of interest to a wider audience, including academics, professionals, and government officials alike.

Soil fauna accounted for 50 % of crop production.
