Book Synopsis Soil Management of Smallholder Agriculture by : Rattan Lal
Download or read book Soil Management of Smallholder Agriculture written by Rattan Lal and published by CRC Press. This book was released on 2014-11-24 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly two billion people depend on hundreds of millions of smallholder farmers for food security. Yet, these farmers’ lives also hang in the balance due to their extreme vulnerability to the risks of soil degradation and depletion, soil exhaustion, climate change, and numerous biotic and abiotic stresses. Soil Management of Smallholder Agriculture explores the potential smallholder agriculture hold for advancing global food security and outlines the challenges to achieving this goal. The book addresses the challenges and opportunities that resource-poor and small landholders face and provides recommended management practices to alleviate soil-related constraints, and increase and sustain crop yield and production. It discusses the cultural, economic, social, and technological aspects of sustainable soil management for smallholder farmers. It then examines soil-related and institutional constraints, principles of sustainable agriculture, soil quality improvement, nutrient and soil fertility management, soil carbon sequestration, soil security, efficient use of resources, and agronomic production. Edited by experts, the book makes the case for the adoption of proven technologies of sustainable intensification, producing more from less, both for advancing agronomic production and adapting to changing climate. It outlines a strategy that will usher in a soil-based Green Revolution by increasing the use efficiency of energy-based inputs such as fertilizers, pesticides, and irrigation to restore soil quality, and sequestering carbon in the terrestrial ecosystems. This strategy helps small farms narrow the gap between the actual and attainable crop yield.

Book Synopsis Sustainable Poverty Reduction in Less-favoured Areas by : Ruerd Ruben
Download or read book Sustainable Poverty Reduction in Less-favoured Areas written by Ruerd Ruben and published by CABI. This book was released on 2007-01-01 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Less-favored areas with limited agricultural potential or difficult access conditions, support 40 percent of the world's rural population suffering from chronic poverty. While agricultural innovations and rural development programs have begun to be implemented within developing countries, they do not address the specific obstacles faced by this large population. Instead, a targeted approach is needed to identify different resource management strategies for particular types of households and communities as well as creating balanced investments aimed at sustainable intensification of rural livelihoods. Such efforts have been the focus of the research program on Regional Food Security Policies for Natural Resource Management and Sustainable Economies (RESPONSE). Through the study of less-favored areas in Africa, Latin America, and South and East Asia, development pathways allowing for the careful adjustment of resource use strategies at the field, farm-household and village level are explored.
Book Synopsis Fishponds in farming systems by : A.J. Zijpp
Download or read book Fishponds in farming systems written by A.J. Zijpp and published by BRILL. This book was released on 2023-08-28 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Throughout the last century, specialisation and intensification were buzz words for farmers in the Western world. However, this approach has not resulted in sustainable development as evidenced by the fact that scientists now need to create technologies to reduce negative impacts. In this book we demonstrate that an alternative exists. Case studies from Bangladesh, Thailand, and Vietnam show that integration and diversification increase both farm productivity and farmers’ incomes. By adopting a participatory approach, farmers and scientists identified a range of technologies that strengthen the positive impacts of integrated aquaculture-agriculture systems for the environment. This book is a collection of refereed papers on a controversial subject in agricultural development. Arguing that sustainability of fish culture in ponds needs a new paradigm - feed the pond to grow fish - two chapters focus on nutrient cycling in such systems. Another chapter makes the case for breeding Nile tilapia for resource poor farmers and presents practical options to avoid the pitfalls that arise from natural tilapia mating in low-input ponds. The book contains chapters on livelihood and development aspects and ends with a general discussion completing the picture of the integrated aquaculture-agriculture systems. Overall it composes a review which addresses one of the key issues of the new century: how to sustainably produce food without compromising environmental integrity."
Book Synopsis A Systems Approach to Agroecology by : Pablo Tittonell
Download or read book A Systems Approach to Agroecology written by Pablo Tittonell and published by Springer Nature. This book was released on 2023-10-14 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: As agroecology gains momentum in the international research-for-development arena, there is an urgent need for methods and tools to support the codesign and evaluation of agroecological systems and their transitions. The social and ecological complexity of agroecosystems, their dynamics, uncertainties and sustainability, calls for a holistic, systemic approach to agroecology. As such, several questions arise for example: how do we deal with heterogeneity, landscapes, biodiversity or learning processes in agroecosystems analysis? How do we categorise diversity or analyse trade-offs in social-ecological interactions? How do we conceptualise, codesign and monitor agroecological transitions? This book sets out to answer these questions by building on the valuable ‘classics’ in agroecology. The book presents a systems perspective that underpins a combination of methodologies, ranging from participatory tools and field observations to mathematical simulation modelling. Researchers, advanced students and transdisciplinary practitioners will find in this book insights and methods to design research and (co-) innovation processes to foster agroecological transitions.

Book Synopsis Agro-Ecological Intensification of Agricultural Systems in the African Highlands by : Bernard Vanlauwe
Download or read book Agro-Ecological Intensification of Agricultural Systems in the African Highlands written by Bernard Vanlauwe and published by Routledge. This book was released on 2013-12-17 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an urgent need to increase agricultural productivity in sub-Saharan Africa in a sustainable and economically-viable manner. Transforming risk-averse smallholders into business-oriented producers that invest in producing surplus food for sale provides a formidable challenge, both from a technological and socio-political perspective. This book addresses the issue of agricultural intensification in the humid highland areas of Africa – regions with relatively good agricultural potential, but where the scarce land resources are increasingly under pressure from the growing population and from climate change. In addition to introductory and synthesis chapters, the book focuses on four themes: system components required for agricultural intensification; the integration of components at the system level; drivers for adoption of technologies towards intensification; and the dissemination of complex knowledge. It provides case studies of improved crop and soil management for staple crops such as cassava and bananas, as well as examples of how the livelihoods of rural people can be improved. The book provides a valuable resource for researchers, development actors, students and policy makers in agricultural systems and economics and in international development. It highlights and addresses key challenges and opportunities that exist for sustainable agricultural intensification in the humid highlands of sub-Saharan Africa.
Book Synopsis Adoption of agricultural innovations by smallholder farmers in the context of HIV/AIDS by : Faith N. Nguthi
Download or read book Adoption of agricultural innovations by smallholder farmers in the context of HIV/AIDS written by Faith N. Nguthi and published by BRILL. This book was released on 2023-08-28 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using tissue-cultured technology is a potentially important way for smallholder banana farmers to improve their yields and income. In the situation of the impoverishing effects of high HIV/AIDS-prevalence in a rural banana-farming community, this applies even more. The research documented in this book examines the balance between required inputs and potential benefits of applying the tissue-cultured technology among HIV/AIDS-affected and non-affected households in Maragua district, Central Kenya, using a livelihood approach. The results show that adoption of the technology and its continued use differs according to the resources endowment of the farming households. Lack of financial and physical capital, notably a water tank, inhibits adoption, irrespective of HIV/AIDS-status. However, households headed by elderly females dominate among the poor households and the HIV/AIDS-affected households. This illustrates how HIV/AIDS interfaces with poverty and, thereby, indirectly with the feasibility of sustainable technology adoption. The research also shows that livelihood decisions and strategies of farming households are influenced by land tenure status (having title deeds or not) and labour constraints at the household level. The latter arise as a consequence of HIV/AIDS-related morbidity and mortality.

Book Synopsis Sustainable Intensification in Smallholder Agriculture by : Ingrid Oborn
Download or read book Sustainable Intensification in Smallholder Agriculture written by Ingrid Oborn and published by Routledge. This book was released on 2017-02-17 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems and institutional innovation. Much of the work represents outputs of the three CGIAR Research Programs on Integrated Systems for the Humid Tropics, Aquatic Agricultural Systems and Dryland Systems. The chapters are based around four themes: the conceptual underpinnings of systems research; sustainable intensification in practice; integrating nutrition, gender and equity in research for improved livelihoods; and systems and institutional innovation. While most of the case studies are from countries and agro-ecological zones in Africa, there are also some from Latin America, Southeast Asia and the Pacific.

This book was released on 2011-08-30 with total page 1339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa can achieve self sufficiency in food production through adoption of innovations in the agriculture sector. Numerous soil fertility and crop production technologies have been generated through research, however, wide adoption has been low. African farmers need better technologies, more sustainable practices, and fertilizers to improve and sustain their crop productivity and to prevent further degradation of agricultural lands. The agricultural sector also needs to be supported by functional institutions and policies that will be able to respond to emerging challenges of globalization and climate change.
Book Synopsis Improved Crop Productivity for Africa’s Drylands by : Tom Walker
Download or read book Improved Crop Productivity for Africa’s Drylands written by Tom Walker and published by World Bank Publications. This book was released on 2016-08-17 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 200 million people living in dryland regions of Sub-Saharan Africa make their living from agriculture. Most are exposed to weather shocks, especially drought, that can decimate their incomes, destroy their assets, and plunge them into a poverty trap from which it is diffi cult to emerge. Their lack of resilience in the face of these shocks can be attributed in large part to the poor performance of agriculture on which their livelihood depends. Opportunities exist to improve the fortunes of farming households in the drylands. Improved farming technologies that can increase and stabilize the production of millet, sorghum, maize, and other leading staples are available. Irrigation is technically and economically feasible in some areas and offers additional opportunities to increase and stabilize crop production, especially small-scale irrigation, which tends to be more affordable and easier to manage. Yet many of these opportunities have not been exploited on a large scale, for reasons that include lack of farmer knowledge, nonavailability of inputs, unfavorable price incentives, high levels of production risk, and high cost. Future production growth in drylands agriculture is expected to come mainly from raising yields and increasing the number of crop rotations on land that is already being cultivated (intensifi cation), rather than from bringing new land into cultivation (extensifi cation). Controlling for rainfall, average yields in rainfed cropping systems in Sub-Saharan Africa are still much lower than yields in rainfed cropping systems in other regions, suggesting that there is considerable scope to intensify production in these systems. Furthermore, unlike in other regions, production of low-value cereals under irrigation is generally not economic in Sub-Saharan Africa unless the cereals can be grown in rotation with one or more high-value cash crops. The long-run strategy for drylands agriculture, therefore, must be to promote production of staples in rainfed systems and production of high-value cereals (for example, rice), horticultural cops, and industrial crops in irrigated systems. Based on a detailed review of currently available technologies, Improved Crop Productivity for Africa’s Drylands argues that improving the productivity and stability of agriculture in the drylands has the potential to make a signifi cant contribution to reducing vulnerability and increasing resilience. At the same time, it is important to keep in mind that in an environment characterized by limited agro-climatic potential and subject to repeated shocks, farming on small land holdings may not generate suffi cient income to bring people out of poverty.
