Globally aquaculture has been increasing rapidly and already accounts for nearly half of all food fish consumed. For developing countries, which produce 90% of the world’s output, aquaculture is a source of protein, employment, income and of foreign exchange. Southeast Asia is an area which has experienced this “blue revolution”. Total aquaculture output in the region increased from less than two million tonnes in 1990 to more than eight million tonnes in 2006. Moreover, the region’s pace of expansion has accelerated. Annual average growth rates in output from 2000 to 2006 were more than double those from 1990 to 2000. Already more than a quarter of food fish in Southeast Asia comes from aquaculture. 相似文献

Demands for sixteen food products are investigated, using data from the Turkish Household Expenditure Survey. The linear approximate almost ideal demand system (LAIDS) is estimated with Shonkwiler and Yen’s two-step procedure. All own-price elasticities are negative and expenditure elasticities positive. Bread, other cereals, bovine, mutton, giblets, and cheese have high expenditure elasticities. Mutton, bovine, and several other protein-rich products are price elastic. Results suggest a mix of gross substitutes and complements, while net substitution is the dominant pattern. Demographic characteristics also play important roles in shaping food demand. The elasticity estimates can inform policy deliberations. 相似文献

West African consumption of wheat and rice is growing rapidly despite technological barriers to production of these cereals in the region. Soaring imports are of particular concern in view of likely consumption trends. Maize imports are also growing rapidly, as is production in the more humid countries, to the detriment of sorghum. The latter is performing relatively better in the drier countries. Possible factors underlying consumption shifts are discussed, including price policies at variance with stated objectives. Possible policies to slow down these shifts are discussed, along with research requirements for effective diagnosis and implementation. 相似文献

This article examines the aims, context and experience of food aid projects in Ethiopia. The major focus is a case study of an Ethiopian food-for-work project — the largest in sub-Saharan Africa — and favourable conclusions are drawn. Factors are identified which have made for this apparent success. Since one factor is local food shortage, consideration is also given to the proposition that the concept of ‘relief aid’ needs a wider definition than heretofore. 相似文献

Despite progress in poverty reduction achieved over the last two decades, Tajikistan’s food security situation remains challenging. Recent studies and analyses have highlighted progress as well as areas that require increased attention from the Government of the Republic of Tajikistan and international development partners. The paper argues that a systems approach that takes into consideration policy interventions by different sectors is required to more effectively improve access and affordability of healthy diets, contributing to a better food security and nutrition situation of the population. 相似文献

The meaning of universal service in telecommunications has changed considerably in the last decade. Technological advances have created the necessity to redefine the legal framework. While the demand for old universal services falls, new and wider services are to be included in the scope of legal obligations such as broadband. In this transformation of public policy toward universal services, political preferences take precedence over economic considerations. Turkey provides a good case in point. In this paper, the authors assess the legal framework of universal services and its institutional structure in Turkey. The tension between enlarging the scope of universal service and pressures on using revenues efficiently is emphasized. 相似文献

Micronutrients are defined as substances in foods that are essential for human health and are required in small amounts. They include all of the known vitamins and essential trace minerals. Micronutrient malnutrition affects ⅓–½ of the global population. It causes untold human suffering and levies huge costs on society in terms of unrealized human potential and lost economic productivity. The goal of this paper is to identify deficiencies in the food system that lead to micronutrient malnutrition and explore and evaluate strategies for its prevention. We examine the impact of agricultural practices on micronutrients in the food supply, including cropping systems, soil fertility and animal agriculture. We then discuss the potential of biofortification – i.e. increasing the concentration of micronutrients in staple food crops through conventional plant breeding or genetic engineering– as a means to reduce micronutrient deficiency. In addition, we discuss the impact of food losses and food waste on micronutrients in the food supply, and we explore successful strategies to preserve micronutrients from farm to plate, including food fortification. Our review of the literature sheds light on the advantages and limitations of alternative interventions to reduce micronutrient deficiencies along the supply chain. We end with recommendations for actions that will reduce the prevalence of micronutrient malnutrition. 相似文献

This paper aims to provide policy makers in low income and middle income countries with a pragmatic review of the critical issues in formulating effective strategies and planning to embrace the next generation of mobile cellular technology. In a context of industry lobbying of governments to promote 5G, the paper attempts to bring clarity to just what are the critical issues, specifically for an industrial policy to deal with this novel but complex technology. Planning for 5G is a series of complicated choices as there are issues at the levels of creating ecosystems to support it, unproven business models, with claims for applications which may not be financially viable, yet, plus confusion over choices of radio spectrum, and selection of equipment suppliers, even potential issues over public health, as well as the real level of industrial and consumer demand beyond the hype. The emphasis here is on the importance of making balanced strategic choices, by identifying the basic issues, in a ‘realpolitik’ fashion - including why embrace 5G at all. The paper develops its insights from lessons learnt in the introduction of the previous mobile generation, LTE, also from policy studies on small cells and on designing auctions for 5G networks, as well as various 5G-focused publications from governments, regulatory authorities, mobile industry associations and global suppliers over the past six years (2015–2020). It examines whether to regulate 5G deployment with a heavy or light-touch regime, also whether to focus on more than the traditional indicators, such as penetration and coverage, or on “transformational outcomes” (as the promotional literature terms them) for the private and public sectors. 相似文献

This article examines the multifaceted notions of food security and food aid through a case-study of a rather exceptional country in political terms - Egypt. Egypt has achieved a high degree of food security with lessened reliance on domestic production and has become one of the largest recipients of cereal food aid. The analysis considers significant questions about the interdependence of food security and food aid, the maintainability of an externally dependent food system, its implicit resource costs and its internal distribution and equity impact. 相似文献

Given the present conditions of demographic growth and the complicated transition toward market economies in Central Asia, the problems of food security and designing policies to achieve it without compromising economic growth are at the forefront of policy agendas in these countries. This paper reviews food policy reforms in Uzbekistan, the Kyrgyz Republic, and Tajikistan in the context of sustainable agricultural development. Analyzing the trends in the agricultural sector during the transition period, it identifies the major impacts of policy reforms on food security and enumerates future challenges for improving food security in these countries. It finds that despite the progress made in reforming their economies toward market-oriented ones, the three countries continue to face food insecurity to varying degrees. It concludes that there is an urgent need to further expand and deepen the reform process by enabling functioning land, labor, and financial markets. 相似文献

This introductory paper presents the results of an international multi-disciplinary research project on the measurement of food consumption in national household surveys. Food consumption data from household surveys are possibly the single most important source of information on poverty, food security, and nutrition outcomes at national, sub-national and household level, and contribute building blocks to global efforts to monitor progress towards the major international development goals.The paper synthesizes case studies from a diverse set of developing and OECD countries, looking at some of the main outstanding research issues as identified by a recent international assessment of 100 existing national household surveys (Smith et al., 2014). The project mobilized expertise from different disciplines (statistics, economics, food security, nutrition) to work towards enhancing our understanding of how to improve the quality and availability of food consumption and expenditure data, while making them more valuable for a diverse set of users. The individual studies summarized in this paper analyze, both theoretically and empirically, how different surveys design options affect the quality of the data being collected and, in turn, the implications for statistical inference and policy analysis.The conclusions and recommendations derived from this collection of studies will be instrumental in advancing the methodological agenda for the collection of household level food data, and will provide national statistical offices and survey practitioners worldwide with practical insights for survey design, while providing poverty, food and nutrition policymakers with greater understanding of these issues, as well as improved tools for and better guidance in policy formulation. 相似文献

National nutrition planning has failed to fulfill its initial promise because of inadequate consideration of political and administrative obstacles to applying the methodology. The political and operational contexts within which multisectoral nutrition planning has occurred are reviewed in order to draw insights and lessons from the experience of the last 10 years. Considered are the political process, macro and micro planning, the multisectoral approach, integration with agricultural and health planning, nutrition interventions, community participation, cost benefit analyses, and information systems evaluation, management and organization. Emphasis on the multisectoral causation of malnutrition has contributed substantially to nutrition programming and remains indispensable for improving nutrition, but requires more thoughtful response to practical implementation problems. Integrating nutrition concerns more effectively into health and agriculture systems offers a more promising approach than efforts to attack malnutrition by encouraging multisectoral nutrition coordinating agencies and national plans. 相似文献

This paper reviews the use, regulation and testing of food additives in the UK. Comparisons are drawn with other industrialized countries. In particular, the reasons (both explicit and implicit) for the use of additives are examined and the institutional mechanisms for their control are described. Since regulatory policy is dependent on toxological expertise, the contribution and adequacy of toxological science is considered. Present regulations are viewed to have been too heavily influenced by the food industry at the expense of the protection of the consumer, and several possible avenues for reform of both toxological science and regulatory policy are explored. 相似文献

The research, development practitioner, and donor community has begun to focus on food loss and waste – often referred to as post-harvest losses (PHL) – in Sub-Saharan Africa. This article reviews the current state of the literature on PHL mitigation. First, we identify explicitly the varied objectives underlying efforts to reduce PHL levels. Second, we summarize the estimated magnitudes of losses, evaluate the methodologies used to generate those estimates, and explore the dearth of thoughtful assessment around “optimal” PHL levels. Third, we synthesize and critique the impact evaluation literature around on-farm and off-farm interventions expected to deliver PHL reduction. Fourth, we suggest a suite of other approaches to advancing these same objectives, some of which may prove more cost-effective. Finally, we conclude with a summary of main points. 相似文献

Managing food price risks and instability is a major challenge in the midst of ongoing food market reforms. Key findings from the papers in this special volume revolve around five broad areas: (i) the sources and magnitudes of food price instability in different country contexts; (ii) the economic and social costs stemming from price instability; (iii) the lessons from food market reforms to date; (iv) the design of policy reforms in ways that promote efficient and stable market development and protect the interests of the poor; and (v) potential policy responses to food price instability in a liberalizing market environment. 相似文献

As efforts to improve diets in high income countries intensify, attention has turned to how policies may influence diet composition. The case studies in this special issue contribute to our understanding of how two main types of policies have influenced food product composition and dietary outcomes: (1) policies affecting food manufacturers’ input costs and (2) information policy affecting competition. Research on the first type of policy is relatively new, but suggests that US commodity policies would not be good policy instruments to influence diets, except through the long run impacts of agricultural research. Research on the impacts of information policy continues to demonstrate that it can spur food industry competition to introduce healthier products, but may not result in healthier diets. International comparisons show where the US experience may have relevance for other high income countries. 相似文献

Modern telecommunications technology is now widely seen as a critical driver in economic development. However, the issues involved in the rapid deployment of this technology are complex and frequently highly controversial. While some issues are technical, the most difficult ones involve changing an institutional framework originally designed for different times and different technologies. The process of changing this framework necessarily involves disruptive change for existing infrastructure and service providers as well as substantial benefits for the economy at large. This paper, based on an extensive series of interviews in Turkey in 2005 as well as published sources, seeks to discuss these issues in light of Turkey's progress to date in taking advantage of advanced available telecommunications technology and the myriad productivity-enhancing services that are associated with it.An important element in developing a more competitive and dynamic sector has been Turkey's long-standing desire to become a member of the European Union (EU). This has encouraged changes in the telecommunications regulatory regime following the guidelines set out in Chapter 19 of the EU “acquis” for candidate members. Nonetheless, substantial further efforts are needed to complete and implement the desired regulatory framework, particularly as it affects the former government monopoly carrier, Turk Telekom and the cable companies. A further limiting factor in recent years has been an overall investment climate characterized by a high level of uncertainty for most investors, regardless of size or nationality.Policy recommendations to help accelerate the deployment of telecommunications technology include a clear reaffirmation of the government's priorities for the sector, a reduction in the level of regulatory uncertainty, strengthening the Board and Staff of the Telecommunications Authority, and reviewing policies to broaden the scope and decrease the cost of telecommunication licenses. 相似文献

Food self-sufficiency gained increased attention in a number of countries in the wake of the 2007–08 international food crisis, as countries sought to buffer themselves from volatility on world food markets. Food self-sufficiency is often presented in policy circles as the direct opposite of international trade in food, and is widely critiqued by economists as a misguided approach to food security that places political priorities ahead of economic efficiency. This paper takes a closer look at the concept of food self-sufficiency and makes the case that policy choice on this issue is far from a straightforward binary choice between the extremes of relying solely on homegrown food and a fully open trade policy for foodstuffs. It shows that in practice, food self-sufficiency is defined and measured in a number of different ways, and argues that a broader understanding of the concept opens up space for considering food self-sufficiency policy in relative terms, rather than as an either/or policy choice. Conceptualizing food self-sufficiency along a continuum may help to move the debate in a more productive direction, allowing for greater consideration of instances when the pursuit of policies to increase domestic food production may make sense both politically and economically. 相似文献
