Assessing the Impact of Cowpea and Sorghum Research and Extension in Northern Cameroon

Throughout Africa, per capita food production has been declining since the early 1960s. Cameroon has sought to counter this trend by increasing agricultural productivity through research and extension. In order to establish future investment priorities, policy makers need to know if past agricultural research investments have earned sufficient returns to justify continued funding. Further, national experiences need to be compared to see if returns varied across programs, and in cases where they did, explanations need to be sought to discover why these variations exist. To address these issues, data were collected in Cameroon and analyzed in order to estimate the benefits and costs of investments in sorghum and cowpea research and extension in northern Cameroon. Specific data that were needed to construct benefit and cost streams included the following: yields of traditional and introduced technologies, area harvested, adoption rates of technological innovations, prices of both inputs and outputs, climatic factors influencing both the research agenda and the returns to this research, and the costs of research and extension efforts. Focusing on the period 1979-87, the analysis addressed three questions: What were the returns to past investments? What factors explained the estimated returns and any variability in returns between the sorghum and cowpea programs? And how did institutions influence these returns and the distribution of their benefits?food security, food policy, cowpea, sorghum, Crop Production/Industries, Research and Development/Tech Change/Emerging Technologies, Downloads July 2008 - June 2009: 17, Q16,

Impacts of U.S. Graduate Degree Training on Capacity Building in Developing Countries: A Case Study of the Pulse CRSP

The Dry Grain Pulses Collaborative Research Support Program (Pulse CRSP) had allocated a major part of its resources to providing graduate degree training (GDT) of scientists/researchers in order to strengthen agricultural research capacity in Africa, Latin America, and the U.S. However, no systematic attempt had been made to assess the impact of this investment. The study adopted the Kirkpatrick framework as a guide for evaluating the impacts of GDT by the Pulse CRSP. The results were drawn from a survey of former trainees and researchers, supplemented by interviews with scientists and program administrators and an institutional case study. An important finding was that over 86% of host country trainees returned to their home country. In their enhanced capacity, trainees made contributions to the advancement of bean/cowpea research that can be attributed to their graduate degree training. Trainees reported that their GDT was necessary for their professional development and was highly relevant to their current job responsibility.Impact assessment, Pulse CRSP, USAID, Training, Graduate degree, Beans, Cowpeas, International Development, Teaching/Communication/Extension/Profession, Q16-R&D-Agricultural technology-Biofuels-Agricultural Extension Services,

Growers' Perspective on Attracting Migrant Labor and Migrants' Workplace Choice in Michigan

This study was conducted to analyze Michigan's migrant farm labor situation. Data were collected from growers and migrants. Growers reported wages, housing, and perquisites as tools they use to attract migrants. Migrants reported housing, wages, grower honesty, and respectful treatment of workers to be key factors in choosing a workplace.Labor and Human Capital,

CAN AGRICULTURAL PRODUCTION IN THE MARGINAL LANDS CONTRIBUTE TO IMPROVING FOOD SECURITY IN THE SAHELIAN AFRICAN COUNTRIES: AN EVIDENCE FROM THE BAS-FOND RICE PRODUCTION IN MALI

To improve national food security, successive Mali governments have always focused on expanding and intensifying production in the government-managed irrigation schemes (Office du Niger), which account for about 50% of domestic rice production. Because the cost of expanding and rehabilitating those schemes is high, the government is looking for complementary cost-effective ways to achieve this goal. The government could increase domestic rice supply by investing in improving the farmer-managed inland valley swamps. Although the government has paid little attention to those marginal lands, farmers have been growing rice in these areas using traditional technologies. This paper used data from a survey of 334 bas-fond farmers and secondary data to examine the potential contribution that these undeveloped bas-fonds could make to improve food security and rice exports in Mali. The study found that, if fully developed, the bas-fonds and flooded plains could produce more rice than is currently being supplied by the Office du Niger, or imported through commercial imports or food aid. As expected, rice yields in the bas-fonds are lower than in the Office du Niger. However, bas-fonds rice production is both financially profitable and provides a higher return per day of family labor than the competing upland crops (maize, sorghum/millet and cotton). In addition, the estimated domestic resources cost ratios show that, compared to the Office d u Niger, bas-fond rice production represents a better use of domestic resources, both for producing rice for home consumption and for the market.Crop Production/Industries, Food Security and Poverty, Land Economics/Use,

FINANCIAL PROFITABILITY OF MALI-SUD BAS-FOND RICE PRODUCTION SYSTEMS

The high costs of rehabilitating and/or expanding government-managed irrigated schemes in Mali (Office du Niger) has prompted policy-makers and researchers to explore the potential for the underdeveloped farmer-managed bas-fond to contribute to ensure an adequate rice supply and increase rural households' incomes. Because little is known about nas-fond rice production in Mali, this paper analyzes its financial profitability based on data collected from a random sample of 221 farmers. Data analysis revealed that there are numerous rice production systems in the bas-fond. Budget analysis showed that the four most common bas-fond production systems yield higher returns than the opportunity cost of labor and they are more profitable than the main upland crops competing with rice for farmers labor (cotton, sorghum/millet, and maize). Within a given bas-fond system, however, profitability varies considerably across farms.Agricultural Finance, Crop Production/Industries,

ON THE USE OF PRODUCTIVITY-INCREASING TECHNOLOGIES IN SUB-SAHARAN AFRICA: THE CASE OF INLAND VALLEY SWAMP RICE FARMING IN SOUTHERN MALI

There is no improved seed-fertilizer technology available that can generate the needed growth in agricultural production in Sub-Saharan Africa to meet food demand by the rapidly increasing population. This paper identifies factors associated with inland valley swamp rice farmers' decisions to adopt "improved" varieties and/or fertilizer. To achieve this objective, input-specific logistic models were estimated using survey-generated data collected from a random sample of 221 rice plots (one per farmer) selected from a purposive sample of 12 Mali-Sud bas-fond villages during the 1995-96 cropping season. The model estimation results show that the farther the village is from the closest market, the lower the probability to adopt the "improved" variety, increasing the size of the rice plot will decrease this probability, and men are more likely to adopt "improved" varieties than women because men have access to credit through CMDT, and more alternative sources of income to finance input purchases than women. For fertilizer, the use of "improved" varieties, the presence of water control infrastructure, and the village experience in cotton production increase the likelihood that a farmer will apply this input. The significance of the village experience in cotton production and women limited access to credit suggests that one of the constrains to a wider use of modern inputs is the absence of a reliable source of these inputs and/or seasonal credits. The significance of village distance to the closest market and the presence of water control the likelihood of using these inputs suggests that there exits some technological payoff associated with well-functioning markets and road improvements because such investments reduce the effective distance between the farm and the market.Crop Production/Industries, Research and Development/Tech Change/Emerging Technologies,

THE IMPACT OF BEAN RESEARCH IN HONDURAS

Since the mid-1980s, bean research in Honduras has focused on the development of improved varieties resistant to key diseases, principally Bean Golden Yellow Mosaic Virus (BGYMV), one of the main constraints to bean production in the country. This paper presents evidence of recent adoption rates of improved bean varieties, the farm-level economic impact of adoption, and the ex post rate of return to bean research in Honduras from 1982-2010. Results from a 2001 farm-level survey in the two principal bean-producing regions in Honduras show that 46 to 51% of bean farmers (depending upon the season) have adopted an improved variety, and that adoption is scale-neutral with respect to farm-size and market orientation. Due to the potential problem of sample selection bias in the adoption of disease-resistant varieties, the farm-level impact of the new varieties was estimated using experimental data to approximate the yield differential between resistant and non-resistant varieties under disease pressure, and survey data was used to approximate the frequency of disease incidence in farmers' fields. An expected utility framework assuming risk neutrality demonstrates that adopters gain an average of 20% in bean income from increased yield stability under disease pressure, although these gains are reduced by 7 to 16% due to market price discounts for the resistant varieties. Under base-level assumptions, the economic rate of return bean research in Honduras during the period 1982-2010 is 40 %.Crop Production/Industries, Research and Development/Tech Change/Emerging Technologies,

Through a Glass, Darkly:The CIA and Oral History

This article broaches the thorny issue of how we may study the history of the CIA by utilizing oral history interviews. This article argues that while oral history interviews impose particular demands upon the researcher, they are particularly pronounced in relation to studying the history of intelligence services. This article, nevertheless, also argues that while intelligence history and oral history each harbour their own epistemological perils and biases, pitfalls which may in fact be pronounced when they are conjoined, the relationship between them may nevertheless be a productive one. Indeed, each field may enrich the other provided we have thought carefully about the linkages between them: this article's point of departure. The first part of this article outlines some of the problems encountered in studying the CIA by relating them to the author's own work. This involved researching the CIA's role in US foreign policy towards Afghanistan since a landmark year in the history of the late Cold War, 1979 (i.e. the year the Soviet Union invaded that country). The second part of this article then considers some of the issues historians must confront when applying oral history to the study of the CIA. To bring this within the sphere of cognition of the reader the author recounts some of his own experiences interviewing CIA officers in and around Washington DC. The third part then looks at some of the contributions oral history in particular can make towards a better understanding of the history of intelligence services and the CIA
