Biofortified staple foods are currently being developed to reduce problems of micronutrient malnutrition among the poor. This partly involves use of genetic modification. Yet, relatively little is known about consumer acceptance of such second‐generation genetically modified (GM) foods in developing countries. Here, we analyse consumer attitudes towards provitamin A GM cassava in the north‐east of Brazil. Based on stated preference data, mean willingness to pay is estimated at 60–70% above market prices for traditional cassava. This is higher than the results from similar studies in developed countries, which is plausible given that micronutrient malnutrition is more severe in developing countries. GM foods with enhanced nutritive attributes seem to be well received by poor consumers. However, the results also suggest that acceptance would be still higher if provitamin A were introduced to cassava through conventional breeding. Some policy implications are discussed.  相似文献

The dramatic rise and fall of world food prices in 2007–8 was largely a result of speculative activity in global commodity markets, enabled by financial deregulation measures in the United States and elsewhere. Despite the recent fall in agricultural prices in world trade, the food crisis has been exacerbated in many developing countries where food prices remain high and even continue to increase. The financial crisis also directly operates to increase food insecurity by imposing constraints on fiscal policies and food imports in balance‐of‐payments constrained developing countries, causing exchange rate devaluation through capital flight and adversely affecting employment, thereby reducing the ability of vulnerable groups to purchase food.  相似文献

This study surveys the experience of agricultural taxation in developing countries in the context of the ongoing policy debate about the tax structure and administration affecting agricultural producers. Using the examples of a number of countries, it analyzes the conceptual and practical problems associated with different tax regimes. Governments in most countries have reduced indirect (export) taxes on agricultural producers. However, the revenue from direct taxes on farmers has not increased. A major problem in most countries has been the measurement of (actual) agricultural income. Different measures for presumed income have been used with varying success. They seem to have the most potential for increased revenue in many countries, but their effective implementation is constrained by the political and administrative considerations.  相似文献

In this article, we discuss some key aspects of biofuel production in developing countries, and where constraints and tradeoffs are likely to occur. We use the example of two countries, Senegal and India, to highlight some of the issues of cost competitiveness, problems with ensuring stable supply of feedstock as well as critical missing links in the biofuels value chain that pose problems to scaling up national programs in these countries. We discuss the particularly problematic nature of jatropha, as a biodiesel feedstock, and underline some helpful guiding principles that can help country‐level policy. We point to an underlying “duality” between a well‐functioning food system and favorable conditions for agribusiness enterprises, such as biofuels, and the relevance it has to achieving food security goals.  相似文献

We analyze the long‐term impacts of large‐scale expansion of biofuels on land‐use change, food supply and prices, and the overall economy in various countries or regions using a multi‐country, multi‐sector global computable general equilibrium model augmented with an explicit land‐use module and detailed biofuel sectors. We find that an expansion of biofuel production to meet the existing or even higher targets in various countries would slightly reduce GDP at the global level but with mixed effects across countries or regions. Significant land re‐allocation would take place with notable decreases in forest and pasture lands in a few countries. The expansion of biofuels would cause a moderate decrease in world food supply and more significant decreases in developing countries like India and Sub‐Saharan Africa. Feedstock commodities (sugar, corn and oil seeds) would experience significant increases in their prices in 2020, but other price changes are small.  相似文献

Deforestation and land use change: sparse data environments   总被引:4,自引:0,他引:4  
Understanding determinants of land use in developing countries has become a priority for researchers and policy makers with a wide range of interests. For the vast majority of these land use issues, the location of change is as important as its magnitude. This overview paper highlights new economic approaches to modeling land use determinants that combine non‐traditional data sources with novel economic models and econometric techniques. A key feature is that location is central to the analysis. All data elements include an explicit location attribute, estimation techniques include the potential for complications from spatial effects, and results are location‐specific. The paper reviews the theory underlying these models. Since this paper is intended to provide the potential new researcher with an introduction to the challenges of this analysis, we present an overview of how remotely‐sensed data are collected and processed, describe key GIS concepts and identify sources of data for this type of econometric analysis. Finally, selected papers using these techniques are reviewed.  相似文献

The European Union’s (EU) import sources for rice include developing countries and least developed countries (LDCs). The EU has made a commitment to allow duty‐free and quota‐free access to rice imports originating in the LDCs from September 2009 onward. The purpose of this article is to answer two questions: (1) does the inclusion of import tariffs lead to different estimated Armington elasticities? (2) when a discriminating tariff is introduced, what happens to the market share of large rice exporters to the EU, especially of poor countries? We present the Armington model, derived from a constant elasticity of substitution (CES) utility function, and a non‐homothetic CES utility functional form, which is more flexible. We then estimate the Armington model, with and without the inclusion of a tariff, and we compare the elasticities. Lastly, we model five scenarios with different discriminated import tariff rates to calculate the changes in the market access of large rice exporters to the EU. Our empirical results show the importance of non‐homothetic preferences and import tariffs. Ignoring import tariffs and the non‐homothetic parameter may produce results which are biased and of uncertain validity. Furthermore, the simulation findings demonstrate that, in spite of a large difference between import tariff rate of Suriname and other countries (scenario V), its market access would not change greatly. This may be caused by supply side problems like poor infrastructures, weak technology and small capacity production in LDCs.  相似文献

In light of continued debate regarding the capacity of small‐scale agricultural producers to compete amidst globalization and/or liberalization, we examine recent trends in the distribution and use of agricultural landholdings in developing nations via refined exploration of the Nicaraguan case. With nationally‐representative, Living Standards Measurement Survey‐type data for the years 1998, 2001, and 2005, we employ Markov chain methods within an information‐theoretic framework in an attempt to advance the analysis of structural transformation in developing countries beyond the examination of trends in mean farm sizes or Gini coefficients, approaches ill‐suited to the detection of the apparent complexities of structural change. Further, while Markov chain analysis has witnessed relatively widespread application in the investigation of structural transformation in developed nations, we offer a novel methodological extension by allowing for the simultaneous exploration of structural transformation across multiple dimensions–namely, structural change in both the distribution and use of agricultural landholdings—as well as the incorporation of microlevel determinants of farm size and land use change. The results of the inquiry, above all, suggest that Nicaragua's agricultural and livestock sector is characterized by a definitive persistence of smallholders. While a moderate tendency toward bifurcation in the distribution of landholdings would appear to obscure any immediate relationship between operational landholdings and land productivity, we contend that such trends are, in fact, consistent with the often observed inverse farm size‐productivity relationship.  相似文献

The paper provides a selective survey of the most significant literature on the rise of contract farming in developing countries, with a focus on sub‐Saharan Africa. The review of the literature illustrates ideological debates around the meaning and significance of contract farming and whether it is good or bad for small‐scale farmers. The paper then divides the review of the literature into three key themes. First, it addresses the quantitative significance of contract farming in Africa, which may not be as important as it is often portrayed. Second, the paper highlights the substantial diversity of contract farming in Africa and problems with excessive generalizations. Third, it discusses the various drivers fuelling the spread of contract farming, which reflect new production conditions and existing constraints, tendencies and counter‐tendencies, and both economic and political responses to changes in production and market conditions in the era of liberalization and globalization. The variety of drivers is substantial and defies generalizations about the emergence of contract farming. Finally, it briefly suggests research questions that tend to be absent in most of the literature on contract farming, and which are important in order to understand the current dynamics of agrarian change and transitions to capitalism in African countries.  相似文献

Index insurance has been heralded as a potential solution to risk management problems faced by smallholder farmers in developing countries. Despite its potential, demand for standalone index insurance contracts has remained low in early field trials. We investigate the willingness to pay for drought index insurance‐backed loans in northern Ghana using contingent valuation. We find that index insurance lowers overall demand for agricultural loans. We also compare micro‐level index insurance, provided directly to farmers, with meso‐level insurance, provided to the credit agency and find that farmers appear to prefer micro‐level insurance. Finally, farmers are willing to pay to avoid basis risk.  相似文献

Unanticipated events can cause considerable economic hardship for poor rural households. Some types of negative shocks, for example weather‐related agricultural losses and vector‐borne diseases, are expected to occur more frequently as a result of climate change. In this paper we measure the role of household‐ and location‐specific characteristics in conditioning behavioural responses to a wide range of idiosyncratic and covariate shocks. We use data from 8,000 rural households in 25 developing countries, compiled in the global database of the Poverty Environment Network. We employ a hierarchical multinomial logit model to identify the importance of characteristics observed at different levels of aggregation on a set of strategies aimed at coping with economic shocks. Results indicate that in response to idiosyncratic shocks, households tend to deplete financial and durable assets, whereas covariate and thus often climate‐related shocks predominantly result in reduced consumption. Households in sites characterised by high asset wealth tend to cope with shocks in a more proactive way than those in sites with average or below average asset wealth, but the role of asset types in conditioning shock responses varies across regions. Our findings have implications for rural development and climate change adaptation strategies.  相似文献

Low agricultural productivity remains the primary source of poverty in the developing regions and yet little is known about the influence on agricultural productivity of domestic and international accumulated R&D knowledge and the channels through which this knowledge is transmitted internationally. Following a large scientific literature, this article argues that R&D and R&D knowledge spillover are ecozone‐specific and, therefore, are transmitted internationally through ecozones, where ecozones are the broadest biogeographic division of the earth's land surface. Using data for a panel of 88 countries, it is shown that international knowledge spillovers are ecozone‐specific and have been an important contributing factor behind the marked widening of the income gap between developed and developing countries since 1983.  相似文献

Rapid structural change is now a major feature of several Southeast Asian economies. It generally involves greatly expanded exports of certain commodities and manufactures accompanied by a large growth in services, and poses serious difficulties for traditional labour-intensive sectors. One important sector affected in this way is that producing natural rubber in Malaysia, Indonesia and Thailand. The difficulties mentioned occur through both “resource pull” effects - which are especially important in raising real wages, and “spending” effects - which tend to lead to an appreciation of the real exchange rate. These effects, and the problems arising from them, are examined and compared for each of the rubber sectors above. While changes of this nature call for diminution in the size of traditional sectors, there is also a need to improve economic efficiency, notably by adopting new technology more appropriate to the emerging resource price configuration, and by moving to an agriculture where off-farm employment and other linkages are increasingly significant. Such adjustment may be both helped and constrained by institutional factors and official policies, which accordingly require careful review. These crucial policy issues, and the degree to which necessary adjustments have been made, are investigated for the rather different contexts in each of the three natural rubber-producing countries. The analysis is thought to have wider relevance for other developing countries with traditional agricultural sectors.  相似文献

The Uruguay Round Agreement on agriculture attempted to lower distortions in global agricultural markets. However, the significant fall in commodity prices in the late 1990s may have reduced the incentives for both developed and developing countries to better integrate into world markets. This study analyzes price linkages and adjustment between developed and developing countries during the post–Uruguay Round period. Prices of two key commodities, long‐grain rice and medium‐hard wheat, are assembled for major exporters and producers. Results of multivariate cointegration analysis suggest partial market integration between developed and developing countries in the post–Uruguay Round period. Developed countries are found to be price leaders in these two markets, and in most cases, changes in their prices have relatively large impacts on those of the developing countries. Developing countries (e.g., Vietnam and Argentina) have faced considerable price adjustment due to changes in the developed countries' prices.  相似文献

This article reviews the emerging trends in global food supply and demand up to 2020, and discusses policy challenges and obstacles to meeting this demand. Data were obtained from the International Food Policy Research Institute's International Model for Policy Analysis of Commodities and Trade (Rosegrant et al.). The country-specific data pertains to 37 countries and regions and 17 food commodities and prices in the world market. Cereal prices are expected to decline by about 11% by 2020; meat prices may decline by 6%. After 2010, cereal prices are expected to dramatically decline. Cereal demand will change with changes in income and urbanization. Maize and coarse grains will be replaced by wheat and rice. Life style changes may lead to a switch from rice to wheat. Growth in food consumption in developed countries will slow. A projected 82% of growth in global cereal consumption and almost 90% of increased global meat demand will occur in developing countries during 1993-2020. Asia alone will account for 48% of increased cereal consumption and 61% of increased meat consumption. 88% of food production growth will occur in developing countries through increased yields and 94% in developed countries. World trade in cereals will increase from an estimated 185 million metric tons annually to 328 million during 1993-2020. Food security for the poor and child malnutrition will remain unimproved. Yield growth is affected by agricultural research, fertilizer and energy use, land degradation, water scarcity, and bad policy. Water scarcity is the most limiting on yield growth. Malnutrition problems present multiple challenges.  相似文献

The financial crisis arose in the industrial countries, but has affected developing countries through higher interest rates, sharp changes in commodity prices, and reductions in investment, trade, migration, and remittances. For most low‐income countries, shocks that affect food prices or wage rates for unskilled workers seem likely to have the biggest impact on poverty, with the declines in key food prices associated with the crisis helping to reduce poverty. Policies to address the crisis must include measures to deal with: financial sector problems; the resulting reductions in aggregate demand; and the particular vulnerabilities of poor people.  相似文献

Multifactor agricultural productivity for seventy countries is calculated using a programming method. Productivity measures are divided into indices that measure technical efficiency and technical change. Agriculture in many developing countries is technically inefficient but technical change has had a greater impact on agricultural productivity. Multifactor productivity is declining in many developing countries where both agricultural output and the use of some agricultural inputs has rapidly grown. The level of education in a country and research services are factors which can explain differences in agricultural productivity growth between countries.  相似文献

This paper quantifies the contribution of agricultural exports to economic growth in developing countries. We estimate the relationship between GDP and agricultural and non‐agricultural exports for 42 countries using panel cointegration methods. Results show that a long‐run relationship exists, the agricultural export elasticity of GDP is 0.07 whereas that of non‐agricultural exports is 0.13, and total exports Granger‐cause GDP, which supports the export‐led growth hypothesis. Structural differences exist in the relationship by broad income group. Balanced export‐promotion polices are implied for the poorest countries, but, for those with higher incomes, higher economic growth is achieved from non‐agricultural exports.  相似文献

High transaction costs and an absence of institutional infrastructure in developing countries prevent comprehensive enforcement of intellectual property rights and generate obstacles to the adoption of genetically modified (GM) crop technology. Governments of developing countries that are members of the World Trade Organization are faced with two options when licensing GM crop technology: (1) attempt to regulate GM crops to the standards of the Agreement on Trade‐Related Aspects of Intellectual Property (TRIPS) or (2) allow a black market in GM seeds and risk trade retaliation from the GM innovator's host country through a TRIPS trade complaint. This paper develops a conceptual model that frames the adopting country's range of licensing options, including a new levy system, and derives welfare measures for each option. The model illustrates how a levy on GM technology can be a welfare‐increasing policy for developing countries, and the operation of a levy is discussed. The conceptual model is applied to Brazil's soybean market and quantitative economic surplus measures are estimated within a calibrated welfare model for a range of licensing scenarios. The model's results suggest that a levy may interfere with the long‐term prospects for innovators to collect monopoly rents in adopting countries.  相似文献
