Book Synopsis Conservation Agriculture by : L. García-Torres
Download or read book Conservation Agriculture written by L. García-Torres and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

Book Synopsis Genetic Enhancement of Sorghum and Millet Residues Fed to Ruminants by : Patricia Kristjanson
Download or read book Genetic Enhancement of Sorghum and Millet Residues Fed to Ruminants written by Patricia Kristjanson and published by ILRI (aka ILCA and ILRAD). This book was released on 1999-01-01 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The estimated present value (US$42 million) of the proposed ILRI/ICRISAT/NARS collaborative research project on genetic improvement of millet and sorghum crop residues indicates fairly attractive returns, even with the cautious assumption made about likely adoption rates and the scope of the benefits (i.e. only meat and milk production in cattle in India). The estimated IRR to this research investment (28%) can be compared to market rates on alternative investments. Most longer-run, low-risk, private-sector investments yield rates of return three times as high as alternative investments. However, this raises the question of what is an appropriate rate of return to expect from 'public'good' type of investment such as the investment in international development oriented research. The same methodological approach was recently used (Kristjanson et al 1999) to estimate potential returns to a similary challenging crop-livestock research area, a vaccine against potential returns to a similarly challenging crop-livestock research area, a vaccine against trypanosomosis (a serious livestock disease that poses the greatest development constraint to mixed livestock-crop systems across Africa). Potential returns to this research were estimated at US$ 118 million, with an IRR of 25%, and a benefit:cost ratio of 15:1. In a comparison of predicted rates of return across 5 crop-livestock related research areas at ILRI, potential research benefits were estimated to outweigh the costs of the research by between 9 and 37 times. Returns of similar magnitudes have also been estimated for other crop improvement research. In an economic analysis of returns to 15 research themes at the Centro International de la Papa (CIP) the NPVs ranged from US$ 1 million to US$ 195 million (average US$ 67 million), with IRRs ranging from 13% to 51% (Walker and Collion 1997). ICRISAT ranked returns to 110 different research areas as part of their research priority-setting process several years ago. The average NPV, net benefit:cost ratio and IRR for the top 20 of those were US$ 61 million (with a range from US$ 8 million to US$ 265 million), 52:1 and 39%, respectively (Kelley et al 1995). Thus it appears that the magnitude of returns predicted in this study are very much in line with returns to similar research investments.
Book Synopsis Research with Farmers by : Steven Charles Franzel
Download or read book Research with Farmers written by Steven Charles Franzel and published by Oxford University Press, USA. This book was released on 1992 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this volume is to show the impact of farming systems research (FSR) activities in Ethiopia on agricultural research and on the development of technologies and policies for small-scale farmers. The work reported is based on research conducted by scientists at the Institute of Agricultural Research, in collaboration with staff from the International Maize and Wheat Improvement Center (CIMMYT), the International Center for tropical Agriculture (CIAT) and the International Livestock Center for Africa (ILCA). Ethiopia is one of the few developing countries where FSR activities have been institutionalized and have had and important influence on the development of new technologies for farmers. Consequently, the research results, as well as the policy analysis, methodology and the institutionalization process, will be relevant to all researchers and change agents concerned with the developing world, whether they be economists, policy makers or administrators.
Book Synopsis Prospects for Saline Agriculture by : R. Ahmad
Download or read book Prospects for Saline Agriculture written by R. Ahmad and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Saline land is a resource capable of significant production. Recent advances in research in breeding for salt tolerance in wheat, biotechnology in rice, and selection and rehabilitation of salt-tolerant plants are of economic importance in arid/saline conditions. This book gives some practical approaches for saline agriculture and afforestation, and describes examples of cultivating salt-tolerant/halophytic plants for commercial interest on salt-affected land or with highly salinized water in Australia, China, Central Asia, Egypt, Pakistan, and Russia. It also explores the possibilities of arid/saline agriculture and afforestation in UAE.
