Agricultural technologies for climate change in developing countries: Policy options for innovation and technology diffusion

Climate has obvious direct effects on agricultural production. The reverse is more apparent than ever as greenhouse gas emissions from agriculture are tallied. The development and effective diffusion of new agricultural practices and technologies will largely shape how and how well farmers mitigate and adapt to climate change. This adaptation and mitigation potential is nowhere more pronounced than in developing countries where agricultural productivity remains low; poverty, vulnerability and food insecurity remain high; and the direct effects of climate change are expected to be especially harsh. Creating the necessary agricultural technologies and harnessing them to enable developing countries to adapt their agricultural systems to changing climate will require innovations in policy and institutions as well. Potential constraints to innovation involve both the private and public sectors in both developing and developed countries. The process of transferring agricultural innovations across agroecological and climatic zones is often subject to agronomic constraints. Often, the most binding constraints occur at the adoption stage, with several factors that potentially impede poor farmers’ access to and use of new technologies. Based on discussions of these constraints, we derive six policy principles and use these principles to suggest several specific investments and policy priorities.     

Research for agriculture in developing countries: The US role

The author argues that the USA can make a great contribution to research on food and agriculture in developing countries. He outlines the organizational and attitudinal constraints to this contribution, reviews previous studies that have recommended a redistribution of research resources, and analyses the reasons why resources should be redirected to increase the US contribution to the solution of world hunger problems.     

Subsistence agriculture and technological options

This is a modified version of a paper presented to the ‘Seminario Internacional sobre Tecnología para el Pequeño Agricultor’, held under the auspices of the IICA-lnstituto Interamericano de Ciências Agrícolas da OEA, Asuncion, Paraguay, 2–6 May 1977. The author wishes to thank Denisard C.O. Alves and Fernando B. Homem de Mello for their constructive comments.     

Urban agriculture,poverty, and food security: Empirical evidence from a sample of developing countries

Urban agriculture may have a role to play in addressing urban food insecurity problems, which are bound to become increasingly important with the secular trend towards the urbanization of poverty and of population in developing regions. Our understanding of the importance, nature and food security implications of urban agriculture is however plagued by a lack of good quality, reliable data. While studies based on survey data do exist for several major cities, much of the evidence is still qualitative if not anecdotal. Using a recently created dataset bringing together comparable, nationally representative household survey data for 15 developing or transition countries, this paper analyzes in a comparative international perspective the importance of urban agriculture for the urban poor and food insecure. Some clear hints do come from our analysis. On the one hand, the potential for urban agriculture to play a substantial role in urban poverty and food insecurity reduction should not be overemphasised, as its share in income and overall agricultural production is often quite limited. On the other hand, though, its role should also not be too easily dismissed, particularly in much of Africa and in all those countries in which agriculture provides a substantial share of income for the urban poor, and for those groups of households to which it constitutes an important source of livelihoods. We also find fairly consistent evidence of a positive statistical association between engagement in urban agriculture and dietary adequacy indicators.     

Telecommunications in developing countries

The conditions in which telecommunication services are established and expanded in the developing countries are very different from those experienced in the industrial nations. The author provides insight into the peculiarities of the telecommunication sector in developing countries, discussing characteristics related to the structure of the sector, system size and quality, telecommunications as a business, limitations to faster growth, and some particular problem areas, including the impact on economic development, especially in rural areas, training and education directed towards high technical and managerial positions, and the manufacture of equipment.     

Food insecurity in developing countries

Despite improvements in the world food predicament, the underlying causes of food crises have not disappeared. The aim of this article is to improve understanding of food security problems in Asia, Africa and Latin America, and to assess the relative merits of alternative national and international intervention schemes. The article includes discussion of the concept of ‘food security’, policies that can be undertaken at the national level, a quantitative assessment of national food insecurity for a sample of LDCs, and an examination of the proposed international policies to enhance food security in food-deficit countries.     

Interconnection regulation in India: Lessons for developing countries

Interconnection is not only a major competition issue per se, it is also a critical element of the basic telecommunications agreement of the WTO. An important issue in interconnection regulation is interconnection charging especially in the context of a dominant incumbent. Most regulators in developing countries face challenges in setting interconnection prices in the absence of market information on the incumbent's or entrant's costs, competition or demand and models suited for developing countries that also adhere to the WTO guidelines. There are few papers that illustrate the challenges faced by regulators in such a context. This paper attempts to bridge the gap by highlighting the nature of interaction between the regulator, incumbent, judiciary and the political environment, the role of formal models in setting interconnection charges and the implications of rapid technological changes in a developing country context through a case study of India.The case study highlights the point that besides independence, it is important to vest enforcement powers in the regulatory agency for it to be credible. Incorporating the WTO interconnection guidelines within a developing country context has implications for network growth and poses challenges to the regulatory processes.Although Telecommunications Regulatory Authority of India (TRAI) started with a distortionary, inefficiently priced network providing low coverage and quality, it has meandered its way to a more reasonable network access pricing regime. The decreasing cost of technology and increasing incomes in India and political interventions in regulation have put pressure on TRAI to provide lower interconnection charges and faster telecom growth. Thus, it is pragmatic for regulators to start with a “quick and dirty” estimate, provided that they can signal the downward trend in interconnection pricing, rather than wait for the “correct” estimates.Adoption of future looking strategies (interconnection exchanges), use of a variety of formal models, and strengthening of regulatory capacity are all necessary steps in fostering a competitive environment. Interconnection regimes set up early in the reform process require a review. For successful competition, effective dispute resolution mechanisms and institutions are also important.     

Food imports of developing countries

The trend of food imports of developing countries and its interpretation are discussed. The author presents an analysis across countries of changes in the food supply balances and cereal imports from the early 1960s to the late 1970s. Changes in food energy supplies have not corresponded closely with changes in domestic food production per head, and the increase in imports tends to be greater in middle income than in low income countries. The balance of payments implications are examined, and the article concludes with a consideration of the reliability of international market supplies.     

Value conflicts in computing developments: Developed and developing countries

The author examines the value conflicts engendered by computing developments in two different institutional settings: electronic funds transfer systems and instructional computing in primary and secondary schools. While specific values depend upon culture and upon the character of the particular institutional setting studied, these two cases can serve as instructive points of departure for examining the value conflicts which generally accompany different modes of computerization in other developed and developing countries. In particular, computing developments in Brazil illustrate some of the parallels and contrasts between developed and developing countries.     

The state of food and agriculture in Islamic countries

This review of the state of food and agriculture in Islamic countries underlines the need for much greater public commitment to agricultural development. Within the Organization of the Islamic Conference (OIC), 44 member nations, exibiting immense geographic and economic diversity, have come together recently to begin to cooperate on increasing food production. It is difficult to generalize about food production conditions in Islamic nations, but basically, within the OIC, total arable land increased from 159 to 167 ha in the 1970s, a small amount unevenly distributed over the group. Dry-land farming has not received enough public attention, and the dependence on cereals grown under rainfed conditions leaves the population vulnerable to fluctuation. Many of the poorer nations have not given the priority to land improvement that has been successful in Egypt, Pakistan, and some other countries. The economic burden of food imports has become lighter in some countries, although in all it continues to be serious. Net cereal imports to Islamic countries rose from 21 to 39 million tons from 1975-83. An overall increase in the per capita dietary energy supplies masks broad differences between the wealthier and poorer nations of the OIC, and between more and less priviledged populations within the societies. A small proportion of financial commitments to agriculture (15%) come from Islamic community donors; this is not a leading program priority. Often spending has been for large capital-intensive projects depending on imported skills and inputs. As a group, the OIC must plan to take advantage of their technical and environmental diversity, and work together to avoid inefficient dispersal of personnel and other resources. Tabular data show selected indicators of agricultural development (e.g. % of food imported, food production growth), average annual rate of food production change related to population growth, per capita dietary energy supplies, and external assistance commitments.     

The food situation in developing countries : Two decades in review

This article presents an overview of the general changes in the food situation in developing countries over the past two decades, and especially since the 1974 World Food Conference. Following an examination of trends in production, consumption and trade in basic food staples of Third World countries, the article looks at possible strategies for improving their food situation.     

Demand for telecommunication services in developing countries

Living standards and economic growth in developing countries are invariably linked to the availability and use of telecom services. Effective policy decisions require the best estimates of the drivers of these services. In this paper, telecommunications demand is estimated in models for residential mainline and mobile telephone service for developing countries for the period 1996–2003. The paper tests for cross-price effects between mainline and mobile service and its findings have important policy implications. It finds residential monthly price elasticity to be insignificant for developing countries, but the connection elasticity is larger than generally found in the literature. Mobile monthly price elasticities are very large. A new and important empirical finding is that although wireline phones are substitutes in the mobile market, the contrary is not true—mobile phones are not substitutes in the wireline market, and in fact may be considered complements. This lack of symmetry has important implications for properly defining telecom markets. Universal service subsidies and competitive market initiatives should be reevaluated in light of the paper's elasticity estimates. Increased competition, income growth and enhanced education may be the ultimate universal service promoters.     

Cereal imports by developing countries: Trends and determinants

After reviewing recent trends of cereal imports of developing countries by region, by income group, and by commodity, the determinants of these imports are analysed by investigating both structural, long-term factors as well as temporary, short-term factors. Level of economic development and population density on arable land are found to be statistically the most significant long-run factors explaining cereal imports by developing countries, while food aid is statistically the most significant short-run factor.     

Wheat in the world food economy: Increasing role in developing countries

Wheat is the oldest and most important of the cereal grains in world food supply. In the last two decades the role of wheat in the world food economy has increased substantially, especially in the developing world. This article describes and analyses the role of wheat and highlights and interprets changes that have occurred in the last two decades of rapid change. The authors analyse, in turn, trends in production, consumption, trade and prices with special emphasis on the developing countries.¹ Finally, the authors speculate on how these trends are likely to be effected by future events.     

Privatizing Highways in the United States

We review the experience of both private toll-roads built in the United States during the 1990s, and argue that the problems they encountered could have been avoided if the length of the franchise contract would adapt to demand realizations. We also argue in favor of adjudicating private toll-roads via BOT-type contracts in competitive (Demsetz) auctions. The lessons of this paper are relevant since growing congestion and troubled government finances have made private toll-roads increasingly attractive in the United States.     

Implications of nanotechnology growth in food and agriculture in OECD countries

This article provides an analysis of the implications of the growth of nanotechnology in the agriculture and food sector in OECD countries. Three main policy challenges are identified related to funding and investment, risk governance, and public acceptance. Each of these interconnected challenges underlines a number of ethical questions that need to be addressed. Several recommendations are laid out to move forward and adapt to these emerging policy issues.     

Concentration in ownership of plant variety rights: some implications for developing countries

This paper explores concentration levels in the ownership of intellectual property rights over plant varieties worldwide. An analysis of data for 30 UPOV member-countries shows a high degree of concentration in the ownership of plant variety rights for six major crops at the national level in the developed world. Much of this concentration has arisen owing to the rapid consolidation of the seed industry through mergers and acquisitions, especially in the 1990s. A high degree of concentration in the ownership of plant variety rights, in combination with recent efforts to strengthen plant variety protection regimes, is likely to have significant effects on the prospects for future innovation in plant breeding and the distribution of market power between companies. For developing countries, concentration in intellectual property right ownership may have important implications for the structure of domestic seed industries and access to protected varieties and associated plant breeding technologies. These implications for developing countries are likely to become apparent in the context of the rapid spread of plant variety protection and access legislation, emerging changes in the international exchange regime for plant material and liberalised investment policies permitting foreign investment in the seeds sector.     

Common Agricultural Policy effects on dynamic labour use in agriculture

The aim of this study is to investigate the effects of direct payments and rural development measures of the EU’s Common Agricultural Policy (CAP) on employment in agriculture. We work with a dynamic labour demand equation augmented by the full set of policy instruments of the CAP, which is estimated on a panel dataset of 69 East German regions. We present results for four estimators which differ in how they eliminate the fixed effects and how they address the endogeneity of the lagged dependent variable. The results suggest that there were few desirable effects on job maintenance in agriculture. While there is some indication that investment subsidies have halted labour shedding on farms, a rise in the general wage level reduced labour use in agriculture. Changes in direct payments had no employment effects. Generally, labour adjustment exhibits a strong path dependency.     

Impact of technology transfer on process engineering in developing countries

Imperfect o r total lack of any effective technology transfer was a major reason for the very limited usefulness of many post-war aid programmes. The paper describes the more sensitive regions of oil refining, petrochemicals and industrial chemicals process design, plant installation and operation which bear on the success or failure of the transfer. The first requirement is a satisfactory availability of technical manpower. In sectors where there is a large investment per unit of production a good deal can 'be left' t o external engineering organizations but where, as in plastic fabrication, the investment of capital is low the demand on indigenous engineering and science skills will be higher. Some technologies, such as refrigeration or desalination are key ones for seeding the local development of engineering skills. Moreover, with manpower development in mind, the investment programme should be staggered to ensure integration with related sectors. Mechanical engineering is a key skill and plans to develop this in the educational system and investment programme of the receiving country should be part of the strategy. Two very important common failings are inattention to critical detail during the initial stages of a project and the fallacy that the process must be designed to minimize capital investment. Plant reliability in a hostile climate and with poor maintenance is a more important consideration than costs. The paper concludes with lists of critical off-site and on-site features and decisions needing attention in the design stage and gives useful guidelines for the selection of plant managers and staff.     

Traditional food traders in developing countries and competition from supermarkets: Evidence from Indonesia

Indonesia’s urban centers recently underwent an explosion of supermarkets. With cheaper, higher quality commodities and better services, supermarkets have the potential to drive traders in traditional markets out of business. In this paper, we evaluate whether this is indeed the case. We find that traditional traders experienced declines in their business. However, both qualitative and quantitative findings indicate that the main cause of decline is not supermarkets. Instead, traditional markets are plagued with internal problems and face increasingly bitter competition from street vendors. Therefore, the policy recommendations include strengthening traditional traders and seriously tackling the problem of street vendors.
