Download or read book Just Enough Nitrogen written by Mark A. Sutton and published by Springer Nature. This book was released on 2020-11-09 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a unique collection of contributions addressing both the ‘too much’ and ‘too little’ sides of the nitrogen story. Building on analyses started at the 6th International Nitrogen Conference, Kampala, the book explores the idea of ‘just enough nitrogen’: sufficient for sustainable food production, but not so much as to lead to unsustainable pollution and climate problems. The range of nitrogen threats examined, solutions evaluated and science-policy analyses presented here has provided the foundation to agree the ‘Kampala Statement-for-Action on Nitrogen in Africa and Globally,’ as reported in this volume. Humanity today faces unprecedented challenges: How to feed a growing population? How to reduce air pollution, water pollution and climate change? How to handle regional differences in an era of increasing globalization? These questions are at the heart of this edited volume which examines the multi-dimensional nature of the global nitrogen challenge. While humans have massively altered the nitrogen cycle, the consequences have become polarized. Some regions have too much nitrogen, associated with pollution and wasteful use of a valuable resource, while other regions have too little nitrogen, leading to constraints on food production and depletion of soil nutrient stocks. The volume provides a unique collection of contributions addressing both the ‘too much’ and ‘too little’ sides of the nitrogen story. Building on analyses started at the 6th International Nitrogen Conference, Kampala, the book explores the idea of ‘just enough nitrogen’: sufficient for sustainable food production, but not so much as to lead to unsustainable pollution and climate problems. The range of nitrogen threats examined, solutions evaluated and science-policy analyses presented here has provided the foundation to agree the ‘Kampala Statement-for-Action on Nitrogen in Africa and Globally,’ as reported in this volume. Together, the contributions in this book are now informing actions by the International Nitrogen Initiative (INI) in working with the United Nations Environment Programme and others to establish the International Nitrogen Management System (INMS). A key outcome has been to catalyse development of the first Resolution on Sustainable Nitrogen Management, as adopted by the fourth UN Environment Assembly (UNEA/EA.4/Res.14). The work is written for researchers and policy makers and all those interested in seeing how sustainable nitrogen management can contribute to meeting many of the UN Sustainable Development Goals.

Book Food Security  Gender and Resilience

Download or read book Food Security Gender and Resilience written by Leigh Brownhill and published by Routledge. This book was released on 2016-01-22 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through the integration of gender analysis into resilience thinking, this book shares field-based research insights from a collaborative, integrated project aimed at improving food security in subsistence and smallholder agricultural systems. The scope of the book is both local and multi-scalar. The gendered resilience framework, illustrated here with detailed case studies from semi-arid Kenya, is shown to be suitable for use in analysis in other geographic regions and across disciplines. The book examines the importance of gender equity to the strengthening of socio-ecological resilience. Case studies reflect multidisciplinary perspectives and focus on a range of issues, from microfinance to informal seed systems. The book’s gender perspective also incorporates consideration of age or generational relations and cultural dimensions in order to embrace the complexity of existing socio-economic realities in rural farming communities. The issue of succession of farmland has become a general concern, both to farmers and to researchers focused on building resilient farming systems. Building resilience here is shown to involve strengthening households’ and communities’ overall livelihood capabilities in the face of ongoing climate change, global market volatility and political instability.

Book Sustainable Intensification to Advance Food Security and Enhance Climate Resilience in Africa

Download or read book Sustainable Intensification to Advance Food Security and Enhance Climate Resilience in Africa written by Rattan Lal and published by Springer. This book was released on 2014-10-10 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 32-chapter volume represents the core of several oral and poster presentations made at the conference. In addition to Introduction and Conclusion sections, the book is thematically divided into 7 sections, namely, 1) Land Use and Farming Systems, 2) Effects of Climate Change on Crop Yield, 3) Soil Nutrient and Water Management for Carbon Sequestration, 4) Rehabilitation of Degraded Lands through Forestry and Agroforestry, 5) Management of Animal Production for Greenhouse Gas Emissions, 6) Smallholder Adaptation to Climate Change, and 7) Economic, Social and Policy Issues. It addresses these themes in the context of sustainable intensification (SI). It implies increasing agronomic production from the existing land while improving/restoring its quality and decreasing the C or environmental footprint. Simply put, SI means producing more from less.

Book Trading the Fruits of the Land

Download or read book Trading the Fruits of the Land written by Tjalling Dijkstra and published by Routledge. This book was released on 2018-12-20 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1997, this volume contributes to the knowledge for the trade of vegetables, fruits and tubers (so-called horticultural commodities). As African policy makers try to keep pace with new developments in private food trade, they require knowledge of the structures of private trade systems and the factors that govern their long-term development. The study analyses the structure and development of horticultural marketing channels in Kenya. It is based primarily on surveys of some 500 farmers in four districts and 750 horticultural traders in 18 market places. Commercial horticultural farmers, domestic traders, export traders, agents, facilitators, marketing cooperatives and processors are all reviewed. The study devotes special attention to the efficiency of collecting wholesalers, and to the development of rural assembly markets. It develops a model which can elucidate vertical differentiation processes in the Kenyan horticultural channels. The analyses show that marketing channel theory can be of great relevance to the developing world. The proposed vertical differentiation model can aid in predicting future changes in horticultural marketing systems, in Kenya as well as in other African countries.

Book Challenges and Opportunities for Agricultural Intensification of the Humid Highland Systems of Sub Saharan Africa

Download or read book Challenges and Opportunities for Agricultural Intensification of the Humid Highland Systems of Sub Saharan Africa written by Bernard Vanlauwe and published by Springer. This book was released on 2014-10-07 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The humid highlands in sub-Saharan Africa (SSA) are characterized by high population densities and require intensification. The Consortium for Improving Agriculture-based Livelihoods in Central Africa (CIALCA) has set up a research for development platform in various mandate areas in DR Congo, Burundi, and Rwanda, aiming to identify improved production, market, and nutrition options and facilitating the access for development partners to these options. This platform is supported by capacity building, multi-stakeholder dialogue, and monitoring and evaluation efforts. The conference, facilitated by CIALCA, aimed to (i) take stock of the state-of the art in agricultural intensification in the highlands of SSA and (ii) chart the way forward for agricultural research for development in the humid highlands of SSA, and more specifically in the recently launched Humidtropics Consortium Research Programme, through keynote, oral and poster presentations, and strategic panel discussions.

Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation has serious global impacts on agronomic, economic, and sociopolitical conditions, however, statistics regarding the degree of these impacts has been largely unreliable. This book aims to standardize the methodology for obtaining reliable and objective data on soil degradation. It will also identify and develop criteria for assessing the severity of soil degradation, providing a realistic scenario of the problem.

Book Farm Management In Peasant Agriculture

Download or read book Farm Management In Peasant Agriculture written by Michael Collinson and published by CRC Press. This book was released on 2019-03-04 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1972, Farm Management in Peasant Agriculture remains the only detailed discussion of on-site research techniques for economists working on the development of small-holder agriculture in Africa. Part 1 describes the conditions of the agricultural sector within which the African peasant farmer must operate, and then outlines an approach to farm management tailored to those conditions. Part 2 sets out the research planning and investigation tasks implied by the approach. Survey techniques, as well as the value of a pre-survey for understanding general attributes of a farm system, are reviewed, and alternative data-collection methods are elaborated. Part 3 shows how research data can be used in planning content for extension programs. Dr. Collinson concludes with the details of a planning method that interpolates changes in farm practice into a model of the existing farm system and that projects a sequence of changes, representing a sequence of extension content, on the basis of farmer acceptability.

Book Systems approaches for agricultural development

Download or read book Systems approaches for agricultural development written by Frits Penning de Vries and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The symposium In the next decades, agriculture will have to cope with an ever-increasing demand for food and raw basic materials on the one hand, and with the necessity to use resources without further degrading or exhausting the environment on the other hand, and all this within a dynamic framework of social and economic conditions. Intensification, sustainability, optimizing scarce resources, and climate change are among the key issues. Organized thinking about future farming requires forecasting of consequences of alternative ways to farm and to develop agriculture. The complexity of the problems calls for a systematic approach in which many disciplines are integrated. Systems thinking and systems simulation are therefore indispensable tools for such endeavours. About 150 scientists and senior research leaders participated in the symposium 'Systems Approaches for Agricultural Development' (SAAD) at the Asian Institute of Technology (AIT), Bangkok, Thailand, in December 1991. The symposium had the following objectives: - to review the status of systems research and modeling in agriculture, with special reference to evaluating their efficacy and efficiency in achieving research goals, and to their application in developing countries; - to promote international cooperation in modeling, and increase awareness of systems research and simulation. The symposium consisted of plenary sessions with reviews of major areas in systems approaches in agriculture, plus presentations in two concurrent sessions on technical topics of systems research. Subjects of studies were from tropical and temperate countries.

Book Innovations as Key to the Green Revolution in Africa

Download or read book Innovations as Key to the Green Revolution in Africa written by Andre Bationo and published by Springer Science & Business Media. 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.
