ASSESSING THE IMPACT OF HIGH-YIELDING VARIETIES OF MAIZE IN RESETTLEMENT AREAS OF ZIMBABWE AgEcon
Bourdillon, Michael; Hebinck, Paul; Hoddinott, John; Kinsey, Bill; Marondo, John; Mudege, Netsayi; Owens, Trudy.
This study is part of a larger effort to explore the impact of agricultural research on poverty reduction. It examines the diffusion and impact of hybrid maize in selected resettlement areas of rural Zimbabwe, paying particular attention to varieties made widely available from the mid-1990s onwards. While “Zimbabwe’s Green Revolution” of the early 1980s was characterized by the widespread adoption of hybrid maize varieties and significant increases in yields, the subsequent diffusion of newer varieties occurred more slowly and had a more modest impact. Several factors account for this. Government now plays a much-reduced role and one that increasingly focuses on “better farmers.” Private-sector institutions that have entered the maize sector operate mainly...

Development in the Midst of Drought: Evaluating an Agricultural Extension and Credit Program in Nicaragua. AgEcon
Mullally, Conner.
This paper measures the impact of year one of the Millennium Challenge Corporation’s Rural Business Development program for small rice farming households on the Pacific Coast of Nicaragua. The program was rolled out in the 2009-2010 agricultural year, which was the driest year on record in the region, likely due to an El Niño event. Estimated impacts show that the program at best had no effect, and at worst led to a 10 percent reduction in yields. These impacts are estimated using an econometric model which uses selection on observables as its identifying assumption, and robustness checks suggest that this is a reasonable approach in this case. Inference accounts for spatial correlation across households of the unobserved determinants of agricultural...

Empirical validity of the evaluation of public policies: models of evaluation and quality of evidence AgEcon
Berriet-Solliec, Marielle; Labarthe, Pierre; Laurent, Catherine E.; Baudry, Jacques.
There is a wide range of evaluation methods. On the basis of which criteria should one method be chosen? On what scientific foundations are the results of numerous evaluations based? How can reliability and empirical validity be tested? The relevance of such questions is heightened in new fields of action such as agri-environmental policy. This paper aims to demonstrate that theoretical advances on level and types of evidence (existence, causality, effectiveness) can help resolve these issues. The main evaluation methods are classified into three main categories, according to their main goal (to learn, measure, understand) and linked to the debate on types of evidence. The analysis is illustrated by comparing evaluation methods in the field of...

Assessing the Impact of the National Agricultural Advisory Services (NAADS) in the Uganda Rural Livelihoods AgEcon
Benin, Samuel; Nkonya, Ephraim M.; Okecho, Geresom; Pender, John L.; Nahdy, Silim; Mugarura, Samuel; Kato, Edward; Kayobyo, Godfrey.
The National Agricultural Advisory Services (NAADS) program of Uganda is an innovative public-private extension service delivery approach, with the goal of increasing market oriented agricultural production by empowering farmers to demand and control agricultural advisory services. Although initial evaluations of NAADS have been quite favourable, these evaluations have been primary qualitative in nature. This study quantifies the initial impacts of NAADS in the districts and sub-counties where the program was operating by 2005. It is based on descriptive analyses of results of a survey of 116 farmer groups and 894 farmers in sixteen districts where the program was operating at the time and four districts where NAADS had not yet begun operating to control...

Analysis of Factors Affecting on Risk Management of Wheat Production Among Wheat Farmers (Razavieh Region, Khorasan-E-Razavi Province, Iran) AgEcon
Sookhtanlo, Mojtaba; Sarani, Valiollah.
The main purpose of this study was to analyze the Factors Affecting on risk management in wheat production among farmers of Razavieh region (Khorasan-E-Razavi province, Iran). Statistical population of the study was 1520 farmers that they had water cultivation. By using of stratified proportional random sampling 156 respondents were selected from 8 villages. For the calculation of the risk-aversion coefficient degree among farmers, the Safety First Rule model was used. The findings revealed that the dominant respondents (65%) were risk-averse. The results of exploratory factorial analysis showed that five factors determined about 74.267 % from total variance for wheat farmers' risk management that consist of: economy & marketing management factor,...

THE IMPACT OF IMPROVED MAIZE GERMPLASM ON POVERTY ALLEVIATION: THE CASE OF TUXPENO-DERIVED MATERIAL IN MEXICO AgEcon
Bellon, Mauricio R.; Adato, Michelle; Becerril, Javier; Mindek, Dubravka.
This study documents how poor small-scale farmers in lowland tropical Mexico use improved maize germplasm and how this contributes to their well-being. It does this by assessing both the direct adoption of improved varieties and examining the process of their “creolization.” By exposing improved varieties for replanting, and in some cases promoting their hybridization with landraces, either by design or by accident, farmers produce what they recognize as “creolized” varieties. Our key hypothesis is that poor farmers benefit from improved germplasm through creolization. Creolization provides farmers with new options, as they deliberately modify an improved technology generated by the formal research system to suit their own circumstances and needs....

CAPACITAÇÃO GERENCIAL DE AGRICULTORES FAMILIARES: UMA PROPOSTA METODOLÓGICA DE EXTENSÃO RURAL AgEcon
Lourenzani, Wagner Luiz.
Family-based agriculture plays an important socio-economical role in Brazilian agribusiness. Its development is considered a precondition for an economically efficient and fair society. There are numerous variables influencing the performance of rural business. Several variables can not be controlled by the farmers, but, there are some variables which can be controlled, as farm management. Problems related to farm business sustainability revel inefficiencies in farm management in general, and more specifically in family based agriculture. Therefore the proposal of a rural extension course in management, acts over this deficiency, providing tools for family-based agriculture. This paper presents a methodological framework of a managerial capacitation...

Policies to Promote Cereal Intensification in Ethiopia: A Review of Evidence and Experience AgEcon
Byerlee, Derek R.; Spielman, David J.; Alemu, Dawit; Gautam, Madhur.
Despite more than a decade of policies placing high priority on cereal intensification, backed by one of the highest rates of public expenditures on agricultural in Africa, Ethiopia has yet to see payoffs in terms of higher and more stable cereal yields, reduced dependency on food aid, improved food security, and lower consumer prices for staples. There is understandable concern about the performance, efficiency and sustainability of the agricultural sector, specifically in terms of the current systems for providing extension services, improved seed, fertilizer, and credit. This paper aims to illuminate possible solutions available to improving the prospects for cereal intensification in Ethiopia. The paper traces the largely state-led policies that have...

Communication Processes in Agro-environmental Policy Development and Decision-Making: Case Study Sachsen-Anhalt AgEcon
Prager, Katrin; Nagel, Uwe Jens.
The development of a decision support approach with regard to agro-environmental programmes is part of a larger research project on agricultural transformation and structural change processes. Research objective are improved communication processes and an enhanced quality of political decision-making. The investigation is based on the assumption that the success of agro-environmental programmes depends largely on their acceptance by all major stakeholders. This implies an early integration of varying interests in the decision-making process. Introducing participatory approaches into a bureaucratic setting poses particular problems. In order to achieve greater efficiency and effectiveness, the introduction of interactive modelling approaches has to be...

Participatory Agricultural Extension from the Prospective of Audience-centered Communication Theory AgEcon
Zhao, Di; Wang, De-hai.
Transformation process to Audience-centered Communication Theory is introduced, as well as the basic idea of the theory in China. It is believed that using Audience-centered Communication theory can help to consolidate the theoretical basis of participatory agricultural extension. The communication essence of agricultural extension activity is studied, which is spreaders send information to farmers; then, farmers filter and process the information, transform it into their own experiences and feed back on time. Internet logical relationship between audience-centered communication and participatory agricultural extension is studied. Effects of Audience-centered Communication Theory on participatory agricultural extension are analyzed. One is that the...

THE IMPACT OF AGROFORESTRY-BASED SOIL FERTILITY REPLENISHMENT PRACTICES ON THE POOR IN WESTERN KENYA AgEcon
Place, Frank; Adato, Michelle; Hebinck, Paul; Omosa, Mary.
This case study explores the relationships between agroforestry-based soil fertility replenishment (SFR) systems (improved fallows and biomass transfer) and poverty reduction in rural western Kenya. It further examines the role that different dissemination approaches play in conditioning which segments of society gain access to information to the technologies and then uses them. The study made use of many different qualitative and quantitative data collection methods and samples from both pilot areas where researchers maintained a significant presence and nonpilot areas where farmers learned of the technologies through other channels. Adoption processes were analyzed quantitatively using almost 2,000 households. Qualitative methods included case studies...

Agricultural Knowledge and Information Systems: A Network Analysis AgEcon
Kaine, Geoff; Doyle, Brendan; Reeve, Ian; Lees, Jim.
Röling and others argue that research and extension should not be seen as separate processes involving distinct institutions which must somehow be linked. Rather, scientists, specialists, extension workers, consultants and producers should be seen as participants in a single agricultural knowledge and information system (AKIS). This perspective on research, extension and adoption as activities that occur within a network offers new insights into the way in which technology transfer occurs, and new ideas as to how to increase the rate of adoption of new ideas and techniques in farming. In this study, we use network management theory and applied network analysis to operationalise the concept of an AKIS and to test the relationships between system...

IMPACTS OF AGRICULTURAL RESEARCH ON POVERTY: FINDINGS OF AN INTEGRATED ECONOMIC AND SOCIAL ANALYSIS AgEcon
Meinzen-Dick, Ruth Suseela; Adato, Michelle; Haddad, Lawrence James; Hazell, Peter B.R..
The extent to which agricultural research has reduced poverty has become an increasing concern of policymakers, donors, and researchers. Until recently, poverty reduction was a secondary goal of agricultural research. The primary focus was on increasing food supplies and reducing food prices, a strategy that was successful in increasing the yields of important food staples. When increased productivity is combined with increased agricultural employment, lower food prices, and increased off-farm employment, agricultural research can be credited with significant reductions in rural poverty. However, these benefits do not necessarily materialize, and thus it is essential to understand how agricultural technologies influence and are influenced by the diverse...
