Download or read book Using the Economic Surplus Model to Measure Potential Returns to International Livestock Research written by Patricia Kristjanson and published by ILRI (aka ILCA and ILRAD). This book was released on 1999-01-01 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study has developed a methodology that builds on the approach to measuring agricultural research returns suggested by Alston et al (1995). We have integrated a herd model to measure the potential size of impact of a new technology, GIS, to predict where this impacts is likely to be felt, and the economic surplus model to estimate some of the costs of trypanosomosis, the potential benefits of controlling it, and potential returns to vaccine research. The advantage of this approach is that it uses field data and GIS analysis to determine where and how much impact research will have on livestock productivity, rather than 'guesstimates' by researchers, as has often been done in previous studies of returns to agricultural research. It is an approach, however, that requires much data and the type of information that is still scarce in many developing countries. This includes evidence of the productivity impacts of a given livestock technology at the herd, rather than individual animal level, and access to GIS data at the lowest adminstrative level possible (e.g. district). Ideally, household level survey data are used to complement the GIS data and verify the recommendation domain. Thus this approach will be enhanced in future analyses by the availability of a wider range of data collected at the household level from different livestock production systems to examine more closely the question 'Impact on whom?'

Available in PDF, EPUB and Kindle. Book excerpt: It is necessary to integrate field data relevant to policy with a global overview with up-to-date information for synthesis into scenarios and a vision of how future research and development in agriculture can best help those who are most needy and have little access to productive resources. The overall task is a huge challenge for policy-makers and the agricultural research establishment. It is also of concern in teaching agricultural students to be able to respond to future challenges. This publication is an attempt to stimulate discussion on future options of research policy, suggesting changes of agricultural R&D for societal development in accordance with the Millennium Development Goals.

This book was released on 1999-01-01 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the factors influencing adoption of three related dairy technologies in coastal Kenya, and assessed the impacts of dairy adoption on household income, employment generation and nutrition status of pre-school children. The technologies studied were adoption of grade and crossbred dairy animals, planting of the fodder Napier grass and use of the infection and treatment method of immunisation against East Coast fever. A series of household surveys was conducted from mid-1997 to mid-1998. The descriptive results from surveys of 202 households in Coast Province indicate that adoption of a grade or crossbred dairy animal may result in substantial increases in household income, can generate paid (secondary) employment, and may improve the nutritional status of pre-school-age children in the Household. Econometric analyses, which controlled for numerous confounding factos, provided less consistent support for the impact of adoption on household income and paid employment. It appears that neither the adoption nor productivity of dairying are constrained by poor availability of technology options. For dairy development activities on the coast, two areas merit atention: mechanisms for easing access to grade and crossbred dairy cattle, either through credit schemes or through self-help smallholder co-operatives, and reducing the disease risks associated with grade and corssbred dairy animals.

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.
