It is increasingly recognized that land can be managed most sustainably through involving local communities. This book highlights the potential of a new methodology of uncovering and stimulating community initiatives in sustainable land management in Africa. Analyses of four contrasting African countries (Ghana, Morocco, South Africa and Uganda) show that as communities directly face the challenges of land degradation, they are likely to develop initiatives themselves in terms of sustainable land management. These initiatives (or ‘innovations’) may be more appropriate and sustainable than those emanating from research stations located far from the communities. The book describes the rationale of the approach used, the set of steps followed, how the project managed to engage the communities to understand the importance of the activities they were undertaking, and how they were stimulated to improve and extend their initiatives and innovativeness. Examples covered include soil fertility, community forestry, afforestation, water, invasive species and grazing land management. Central to the book is the way communities, and scientists, interacted between the four countries and learnt from each other. The book also shows how the initiatives were outscaled locally.

Agriculture in Sub-Saharan Africa is constrained by highly variable rainfall, frequent drought and low water productivity. There is an urgent need, heightened by climate change, for appropriate technologies to address this problem through managing and increasing the quantity of water on farmers’ fields – water harvesting. This book defines water harvesting as a set of approaches which occupy an intermediate position along the water-management spectrum extending from in situ moisture conservation to irrigated agriculture. They generally comprise small-scale systems that induce, collect, store and make use of local surface runoff for agriculture. The authors review development experience and set out the state of the art of water harvesting for crop production and other benefits in Sub-Saharan Africa. This includes an assessment of water harvesting schemes that were initiated two or three decades ago when interest was stimulated by the droughts of the 1970s and 1980s. These provide lessons to promote sustainable development of dryland agriculture in the face of changing environmental conditions. Case studies from eight countries across Sub-Saharan Africa provide the evidence base. Each follows a similar format and is based on assessments conducted in collaboration with in-country partners, with a focus on attempts to promote adoption of water harvesting, both horizontally (spread) and vertically (institutionalization). Introductory cross-cutting chapters as well as an analytical conclusion are also included.
