Paperback. Condizione: New. This specially curated collection features four reviews of current and key research on supporting cereal production in sub-Saharan Africa.The first chapter reviews how research and development can support smallholder wheat farmers through improving access to resources and services. The chapter considers current obstacles faced by smallholder farmers, including biophysical limitations such as climatic issues, as well as socio-economic limitations such as land availability.The second chapter assesses the importance of increasing the adoption rate of improved maize technologies within smallholder farming households across Africa. The chapter discusses the economic and institutional barriers inhibiting adoption, as well as farmer attitudes to innovation.The third chapter describes the effect of poor soil fertility, drought and weeds on maize yields in West Africa. The chapter considers strategies for mitigating these constraints, including nutrient management using fertilizers, weed management and resistant varieties of maize.The final chapter discusses phosphorus scarcity in areas of West Africa and details the need to improve sorghum breeding to enhance the crop's tolerance to low-phosphorus soil conditions.…

Octavo, paperback,450 pp.,black and white illustrations. Marine mammals command a high level of public attention, reflected in specific legislation for their protection and management in many countries. They also present particular challenges to ecologists and conservation biologists. They are mostly difficult to observe, they occupy an environment that is vast in its three dimensional extent, there are often perceived conflicts between marine mammals and people, and furthermore several species are now close to extinction. Marine mammals have some intriguing features in their biology - the ability to dive to crushing depths, to perform breath-hold dives that defy our current understanding of mammalian physiology, and many have an ability to hunt down prey using sophisticated sonar that we are only just beginning to understand. Many species also have complex social structures. We still have much to learn about these extraordinary animals so a comprehensive and authoritative overview of current methodology is now timely. The intention of this book is both to summarize the state-of-the-art and to encourage innovation and further progress in this research field.…
