Description : Read Now Conservation Agriculture For Africa by Amir H Kassam and you can download with pub, pdf, txt, doc, and more file format with free account. tillage agriculture has led to widespread soil and ecosystem degradation globally. this is especially so in africa where traditional and modern tillage-based agricultural practices have become unsustainable due to severe disturbance and exploitation of natural resources, with negative impacts on the environment and rural livelihoods. in addition, agriculture in africa today faces major challenges including increased costs of production and energy, the effects of climate change, and the lack of an effective paradigm for sustainable intensification, especially for small- and medium-size holdings. africa is facing a serious challenge to food security and as a continent has not advanced towards eradicating hunger. in addition, the population is still growing much faster than on most other continents. this pressure has led to the emergence of no-till conservation agriculture as a serious alternative sustainable agriculture paradigm. in africa, in recent years, conservation agriculture techniques and methods have spread to many countries, as greater development, education and research effort are directed towards its extension and uptake. this book is aimed at agricultural researchers and scientists, educationalists, and agricultural service providers, institutional leaders and policy makers working in the fields of sustainable agriculture and international development, and also at agroecologists, conservation scientists, and those working on ecosystem services.

Description : Read Now Building A Resilient And Sustainable Agriculture In Sub Saharan Africa by Abebe Shimeles and you can download with pub, pdf, txt, doc, and more file format with free account. what are the challenges and action points for agricultural sustainability in sub-saharan africa? this open access collection of papers offers technical analyses, policy recommendations and an overview of success stories to date. each carefully selected paper provides valuable insights for improved policy making and defines relevant strategic priorities on africa’s sustainable transformation process, which is in line with the international development agenda. although agriculture remains the main source of income for africa’s population, the sector is rain-fed subjecting it to the vagaries of weather and climate change. this volume demonstrates the rationale of developing a competitive, inclusive and sustainable agribusiness sector for africa’s food security and structural transformation. from the impact of bioenergy crop adoption and drought index insurance to agro-industrialization, this volume is important reading for individual researchers, academic associations and professional bodies interested in african agricultural development.

Description : Read Now Biological Nitrogen Fixation Towards Poverty Alleviation Through Sustainable Agriculture by Felix D. Dakora and you can download with pub, pdf, txt, doc, and more file format with free account. poverty is a severe problem in africa, asia, south america and even in pockets of the developed world. addressing poverty alleviation via the expanded use of biological nitrogen fixation in agriculture was the theme of the 15th international congress on nitrogen fixation. because nitrogen-fixation research is multidisciplinary, exploiting its benefits for agriculture and environmental protection has continued to attract research by diverse groups of scientists, including chemists, biochemists, plant physiologists, evolutionary biologists, ecologists, agricultural scientists, extension agents, and inoculant producers. the 15th international congress on nitrogen fixation was held jointly with the 12th international conference of the african association for biological nitrogen fixation. this joint congress was hosted in south africa at the cape town international conv- tion centre, 21–26 january 2007, and was attended by about 200 registered participants from 41 countries world-wide. during the congress, some 100 oral and approximately 80 poster papers were presented. the wide range of topics covered and the theme of the congress justifies this book’s title, nitrogen fixation: applications to poverty alleviation.

Description : Read Now Land And Water Management In Southern Africa by Calvin Nhira and you can download with pub, pdf, txt, doc, and more file format with free account. the southern african development community (sadc) and its member states are making renewed efforts to revive agriculture in the region. given that much of it is water-stressed, appropriate and sustainable land and water management practices are vital to achieving this objective. recognising this, sadc's land and water management applied research and training programme has convened two scientific symposiums. held in lilongwe, malawi, in february 2006, the inaugural symposium brought together r&d practitioners from 10 participating sadc countries to deliberate on land and water management for sustainable agriculture, and discuss how the most recent research and development advances in land and water management might be made more relevant to policy-makers as well as the region's small-scale farmers. the edited contributions to the first symposium appear in this volume. the second symposium was held in gaborone, botswana, in february 2007, and brought together regional experts to discuss opportunities for improving water use and water use efficiency in agriculture in semi-arid and arid areas. the edited contributions to the second symposium appear in a companion volume entitled land and water management in southern africa: towards better water use in agriculture in semi-arid and arid areas (aisa 2008). it is hoped that these two volumes will help to disseminate regional expertise on land and water management to a wider audience, thus helping policy-makers and others to strengthen the agricultural sector in the region, and, in so doing, improve its food security and the wellbeing of its people.

Description : Read Now Sustainable Intensification To Advance Food Security And Enhance Climate Resilience In Africa by Rattan Lal and you can download with pub, pdf, txt, doc, and more file format with free account. 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.
