Book Description
Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Book Description
Rainforests are rapidly being cleared in the humid tropics to keep pace with food demands, economic needs, and population growth. Without proper management, these forests and other natural resources will be seriously depleted within the next 50 years. Sustainable Agriculture and the Environment in the Humid Tropics provides critically needed direction for developing strategies that both mitigate land degradation, deforestation, and biological resource losses and help the economic status of tropical countries through promotion of sustainable agricultural practices. The book includes: A practical discussion of 12 major land use options for boosting food production and enhancing local economies while protecting the natural resource base. Recommendations for developing technologies needed for sustainable agriculture. A strategy for changing policies that discourage conserving and managing natural resources and biodiversity. Detailed reports on agriculture and deforestation in seven tropical countries.

Book Description
Human ecology is ultimately part of a general theory of society. This is the argument developed here by Roy Ellen, whose exploration of the interplay between social organization and ecology in small-scale subsistence systems has direct bearings both on the investigation of human environmental relations in general and on contemporary social theory. He argues that while ecological study of non-industrial societies cannot be elevated to the status of theory, domain or discipline, it can be represented as a single 'problematic' that historically has acquired some degree of autonomy and which continues to make a significant contribution to a wider anthropology. Dr Ellen introduces his subject matter through an extended and systematic discussion of some major frameworks developed within the last hundred years to examine and explain facets of the relationship between culture, social organization and the environment: determinism, possibilism, cultural ecology, systems theory and ideas derived from modern biology. He follows this with a detailed review and appraisal of important recent research involving the use of ecological models, methods and data. This original and innovative study of the pre-eminently social character of human ecological relations will be of considerable interest to all students and researchers concerned with understanding the nature of the relationship between human beings and their environments.

Book Description
Pastoralism has shaped livelihoods and landscapes on the African continent for millennia. Mobile livestock husbandry has generally been portrayed as an economic strategy that successfully met the challenges of low biomass productivity and environmental variability in arid and semi-arid environments. This volume focuses on the emergence, diversity, and inherent dynamics of pastoralism in Africa based on research during a twelve-year period on the southwest and northeast regions. Unraveling the complex prehistory, history, and contemporary political ecology of African pastoralism, results in insight into the ingenuity and flexibility of historical and contemporary herders.

Book Description
This book is based on the findings of a long-term (2000-2014) interdisciplinary research project of the University of Hohenheim in collaboration with several universities in Thailand and Vietnam. Titled Sustainable Land Use and Rural Development in Mountainous Areas in Southeast Asia, or the Uplands Program, the project aims to contribute through agricultural research to the conservation of natural resources and the improvement of living conditions of the rural population in the mountainous regions of Southeast Asia. Having three objectives the book first aims to give an interdisciplinary account of the drivers, consequences and challenges of ongoing changes in mountainous areas of Southeast Asia. Second, the book describes how innovation processes can contribute to addressing these challenges and third, how knowledge creation to support change in policies and institutions can assist in sustainably develop mountain areas and people’s livelihoods.
