Download or read book Food Crop Production by Smallholder Farmers in Southern Africa written by Ambayeba Muimba-Kankolongo and published by Academic Press. This book was released on 2018-02-07 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food Crop Production by Smallholder Farmers in Southern Africa: Challenges and Opportunities for Improvement evaluates traditional cultivation practices used by smallholder farmers, providing a synthesis of the latest information on increasing crop yield through adoption of research innovations. The book catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector including: management practices that reduce net carbon emissions; technologies that improve soil structures and conserve the natural resources base; means of empowering female resources along value chains; and government commitment to adopt policies that enhance agriculture productivity by encouraging farmers to use environmentally sound cultivation technologies. Traditional farming techniques often produce negative impacts on the environment and ecosystem resulting in outbreaks of diseases and pests. In addition to the region's recurrent droughts, these outbreaks of numerous diseases and pests, weeds and other invasive plants put thousands at risk of poverty and hunger, as well as malnutrition. This book presents enhanced agricultural production technologies for ensuring adequate food production, safety and nutritional quality for the population of Southern Africa and forms the basis for an increased SADC regional effort in food production through which financial and trade institutions can improve stakeholder capacities, encourage micro-enterprise development and enhance employment and regional trade. - Provides a critical synthesis of data and information for increasing crop yield through adoption of research innovations - Evaluates traditional and scientific interventions that address food security issues of the poor farmers in the region - Presents agro-ecologies of countries in the region and how they relate to various cultivation practices - Catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector
Download or read book Sustainable Agriculture and the Environment in the Humid Tropics written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Amazonian Dark Earths Wim Sombroek s Vision written by William I. Woods and published by Springer Science & Business Media. This book was released on 2008-11-16 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amazonian soils are almost universally thought of as extremely forbidding. However, it is now clear that complex societies with large, sedentary populations were present for over a millennium before European contact. Associated with these are tracts of anomalously fertile, dark soils termed ‘terra preta’ or dark earths. These soils are presently an important agricultural resource within Amazonia and provide a model for developing long-term future sustainability of food production in tropical environments. The late Dutch soil scientist Wim Sombroek (1934-2003) was instrumental in bringing the significance of these soils to the attention of the world over four decades ago. Wim saw not only the possibilities of improving the lives of small holders throughout the world with simple carbon based soil technologies, but was an early proponent of the positive synergies also achieved in regards to carbon sequestration and global climatic change abatement. Wim’s vision was to form a multidisciplinary group whose members maintained the ideal of open collaboration toward the attainment of shared goals. Always encouraged and often shaped by Wim, this free association of international scholars termed the “Terra Preta Nova” Group came together in 2001 and has flourished. This effort has been defined by enormous productivity. Wim who is never far from any of our minds and hearts, would have loved to share the great experience of seeing the fruits of his vision as demonstrated in this volume.

Download or read book Agriculture Environment and Sustainable Development written by Rukhsana and published by Springer Nature. This book was released on 2022-09-30 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is intended to provide a comprehensive understanding of recent innovations related to the study of agricultural and environmental management for sustainable development. The book clearly identifies why the fight to achieve sustainable development in agricultural production must be fought along a broad multidisciplinary front to overcome issues such as soil erosion, poor water quality, pesticide contamination, and food insecurity. Readers are given a broad exposition of the trends and current practices of basic principles on sustainable agriculture, along with a detailed understanding of the use of sustainable agriculture to develop environmentally sustainable food production systems. The chapters describe the ecological sustainability of agricultural systems, current innovations to improve efficiency in the use of resources for sustainable agriculture, and the proposal for technological options and new areas of research in this very significant field of agriculture. The authors aim to provide readers with a good subject understanding which will assist in the identification of agricultural development, environmental risk, sustainable resource management and design of appropriate responses. This book will be very helpful for students, researchers and practitioners interested in the fields of agriculture, environment and sustainable development.

Download or read book Managing Organic Matter in Tropical Soils Scope and Limitations written by Christopher Martius and published by Springer Science & Business Media. This book was released on 2002-01-31 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that soil organic matter declines when land is taken into cultivation, and that the productivity of new agricultural land is governed by fertility contributions from decomposing natural organic matter. The expansion of agriculture to ever new and more fragile lands, particularly in tropical and developing regions, causes environmental degradation with local effects on soil quality, regional effects on landscape integrity and water quality, and global effects on carbon cycles and the atmosphere. This book summarizes current knowledge of the properties and dynamics of soil organic matter in the tropics, its role in determining soil quality, its stability and turnover, and the options for management in the context of tropical landuse systems, for a readership of resource scientists, economists and advanced students. Maintenance of organic matter is critical for preventing land degradation. Case studies and practical applications are therefore an important part of the book, as are the exploration of future directions in research and management.
