A comparative analysis of the technical efficiency of rain-fed and smallholder irrigation in Ethiopia AgEcon
Makombe, Godswill; Namara, Regassa E.; Hagos, Fitsum; Awulachew, Seleshi Bekele; Ayana, Mekonnen; Bossio, Deborah A..
Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains...

A hedonic approach to estimating the supply of variety attributes of a subsistence crop AgEcon
Edmeades, Svetlana.
The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of...

A standard computable general equilibrium (CGE) model in GAMS AgEcon
Lofgren, Hans; Harris, Rebecca Lee; Robinson, Sherman.
Over the past decade, the increasing power and reliability of microcomputers and the development of sophisticated software designed specifically for use with them has led to significant changes in the way quantitative food policy analysis is conducted. These changes cover most aspects of the analysis, ranging from the collections and analysis of socioeconomic data to the conduct of model-based policy simulations. The venue of the computations has shifted from off-site mainframes dependent on highly trained operators and significant capital investment in supporting equipment, to desktop and laptop computers dependent only on the occasional availability of electricity. This means that it is now feasible to quickly transfer new techniques between IFPRI and...

Adoption of Hybrid maize in Zambia: effects on gender roles, food consumption, and nutrition AgEcon
Kumar, Shubh K..
Enhanced agriculture productivity in sub-Saharan Africa is critical to promote economic growth and poverty alleviation and to avoid increasing food scarcities in the region. The impact of commercialization and intensification of agriculture on the well- being of the rural poor depends on how they are carried out. Past research by IFPRI and collaborating institutions on commercialization of small- scale farming in about a dozen countries provided new knowledge about the relationships between commercialization and rural well- being as measured by incomes, consumption, and nutrition. These links were shown to depend greatly on household behavior, which in turn is influenced by intrahousehold processes. A better understanding of these processes is likely to...

Agricultural Growth and Industrial Performance in India AgEcon
Rangarajan, C..
In “The Role of Agriculture in Economic Development,” written nearly a quarter of a century ago, Bruce Johnston and I discussed the principal means by which agriculture could assist in transforming a traditional low-income economy in a modern high-income one. In the intervening years the literature and much of the practice of development has been dominated by either emphasis on industrialization, independent of agricultural development, or on agriculture as a provider of basic human needs, independent of commercialization and industrialization. Perhaps the time is ripe to pick up the old threads of a dynamic interaction between agriculture and industry. Those threads lead to a very specific strategy for development of agriculture itself in which...

Agricultural Growth and Structural Changes in the Punjab Economy: An Input-output Analysis AgEcon
Bhalla, G.S.; Chadha, G.K.; Kashyap, S.P.; Sharma, R.K..
This research report is part of IFPRI's continuous efforts to understand the relationship between technological change in agriculture and overall economic growth that expands employment and income opportunities for the poor in developing countries. The research is a collaborative effort with the Centre for the Study of Regional Development at Jawaharlal Nehru University in New Delhi. The study documents and analyzes the structural changes that have occurred in the Punjab economy since the green revolution of the mid-1960s. With two input-output tables—one for 1969/70 and the other for 1979/80—the authors have traced the sources of structural changes and examined the changes in the intersectoral linkages and the quantum of indirect and induced income and...

Agricultural Growth Linkages in Sub-Saharan Africa AgEcon
Delgado, Christopher L.; Hopkins, Jane; Kelly, Valerie A.; Hazell, Peter B.R.; McKenna, Anna A.; Gruhn, Peter; Hojjati, Behjat; Sil, Jayashree; Courbois, Claude B..
The wide spread increase in rural purchasing power under the Green Revolution in Asia during the 1970s was key to increased rural employment and industrialization. Studies suggested that an extra dollar of agricultural income was typically associated with an additional $0.80 of nonagricultural income from local enterprises stimulated by the spending of farm house holds. Studies in Africa, where the Green Revolution was harder to discern, tended to be much more pessimistic. This report revisits these issues using especially detailed panel data sets on rural consumption and incomes, collected by IFPRI and collaborating national institutions for a variety of purposes during the mid to late 1980s in Burkina Faso, Niger, Senegal, Zambia, and Zimbabwe. Results...

An economic assessment of banana genetic improvement and innovation in the Lake Victoria Region of Uganda and Tanzania AgEcon
Tushemereirwe, Wilberforce K..
This research report highlights the findings from a set of studies undertaken by the International Food Policy Research Institute, along with several national and international research institutions, to assess the economic impact of improved cultivars and management practices on smallholder farmers in the Lake Victoria Region of Uganda and Tanzania— an area where the cooking banana is both economically and culturally important. Genetic transformation is a promising alternative for improving the resistance of banana plants to the pests and diseases that cause serious economic losses, because bananas, unlike rice, wheat, and maize, are difficult to improve through conventional breeding techniques. The team of researchers posed three broad questions: What is...

An exploration of the potential benefits of integrated pest management systems and the use of insect resistant potatoes to control the Guatemalan Tuber Moth (Tecia solanivora Povolny) in Ventaquemada, Colombia AgEcon
Falck-Zepeda, Jose Benjamin; Barreto-Triana, Nancy; Baquero-Haeberlin, Irma; Espitia-Malagon, Eduardo; Fierro-Guzman, Humberto; Lopez, Nancy.
CORPOICA and IFPRI implemented a research project in Ventaquemada, Colombia. The project’s goal was to asses the benefits of Integrated Pest Management (IPM) practices and the potential of Genetically Modified insect resistant (Bt) potatoes to manage damage caused by the Guatemalan Tuber Moth (Tecia solanivora Povolny). The Guatemalan Tuber Moth is particularly destructive because field spraying on the adult stage is ineffective and there exists damage specificity to the tubers. Excessive pesticide sprays have resulted in resistance to several insecticides. Insect resistant (Bt) potatoes has been shown an effective means to control other members of the Tuber Moth complex. Thus a Bt potato may play a role in managing Tecia in Colombia. This is an ex ante...

An Open-Access Fishery with Rational Expectations AgEcon
Berck, Peter; Perloff, Jeffrey M..
How potential entrants to an open-access fishery form their expectations determines the fishery’s adjustment path to a steady state but not the steady state values themselves. It is well known that, in the standard model with myopic expectations (those based on current values), boats enter the fishery only when the fish stock is greater than its steady state stock. We show that, with rational expectations (perfect foresight), however, boats may enter when the fish stock is much lower than its steady state value if the boat fleet is sufficiently small. This paper contrasts myopic and rational expectations within a general dynamic model of an open-access fishery.
