Consequences of Deforestation for Women’s Time Allocation, Agricultural Production, and Nutrition in Hill Areas of Nepal AgEcon
Kumar, Shubh K.; Hotchkiss, David.
In the face of growing concerns about the environment, policy makers in developing countries find themselves increasingly pressured to choose between environmental deterioration in the long run and the growing demands of poor populations in the short run. Some environmentalists point to new technology –irrigation, fertilizer, and pesticides- as the basis of ecological decay in rural areas. A number of studies have shown, instead, that expanding farm yields in less fragile area through modern technology offers a viable alternative to stripping the land to expand crop area in marginal soils. In the hill areas of Nepal, as many developing countries, women’s work is the key not only to the functioning of the household but also a necessary supply of field...

The Food Stamp Scheme in Sri Lanka: Costs, Benefits, and Options for Modification AgEcon
Edirisinghe, Neville.
Many developing countries attempt to assist low-income households to improve their nutritional intake by providing direct or indirect income transfers. The latter are more common and usually take the form of price subsidies on a range of staple foods. Direct transfers, such as issues of food coupons, are not as widely used as price subsidies. In this regard, the case of Sir Lanka is somewhat unusual, for over four decades it followed a policy of subsidizing food prices, and during the late 1970s, this policy was replaced by a direct transfer scheme in the form of food stamp program. An analysis of the former food subsidy scheme of Sri Lanka was the subject matter of IFPRI Research Report 13, The Impact of Public Foodgrain Distribution on food Consumption...

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...

Government expenditures on agriculture in Latin America AgEcon
Elias, Victor Jorge.
Government expenditure is primarily determinant of the pace and pattern of agricultural growth. The size of government allocations to agriculture is an important indicator of government commitment to agricultural growth. How the resource are allocated is an important determinant of the efficiency of agriculture growth. Despite the central role of government expenditure little comparative analysis has been made of its size, its allocation, and its effect on agricultural production. As a result, there has been little pressure to develop an adequate data base for such requisite data discourages initiation of such analysis. In the research reported her Victor Elias concentrates on developing an adequate data base for analyzing government expenditures on...

The role of agriculture in development implications for Sub-Saharan Africa AgEcon
Diao, Xinshen; Hazell, Peter B.R.; Resnick, Danielle; Thurlow, James.
This paper provides a nuanced perspective on debates about the potential for Africa’s smallholder agriculture to stimulate growth and alleviate poverty in an increasingly integrated world. In particular, the paper synthesizes both the traditional theoretical literature on agriculture’s role in the development process and discusses more recent literature that remains skeptical about agriculture’s development potential for Africa. In order to examine in greater detail the relevance for Africa of both the “old” and “new” literatures on agriculture, the paper provides a typology of African countries based on their stage of development, agricultural conditions, natural resources, and geographic location… More broadly, the paper demonstrates that conventional...

A comparative analysis of the technical efficiency of rain-fed and smallholder irrigation in Ethiopia AgEcon
Makambe, 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...

Impacts of considering climate variability on investment decisions in Ethiopia AgEcon
Block, Paul J.; Strzepek, Kenneth M.; Rosegrant, Mark W.; Diao, Xinshen.
Extreme interannual variability of precipitation within Ethiopia is not uncommon, inducing droughts or floods and often creating serious repercussions on agricultural and non-agricultural commodities. An agro-economic model, including mean climate variables, was developed to assess irrigation and road construction investment strategies in comparison to a baseline scenario over a 12-year time horizon. The motivation for this work is to evaluate whether the inclusion of climate variability in the model has a significant effect on prospective investment strategies and the resulting country-wide economy. The mean climate model is transformed into a variable climate model by dynamically adding yearly climate-yield factors, which influence agricultural...

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...

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...
