Critical issues suggested by trends in food,population, and the environment to the year 2020

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.     

The significance of different realms of value for agricultural land in Sweden

The demand for additional agricultural land is expected to rise by approximately 50 per cent by 2050 on a global level, and agricultural land of high quality needs to be preserved to ensure future food security. However, agricultural land per capita is decreasing. One of the main reasons for this in the EU and globally is the building of houses or infrastructure on agricultural land. There is a possibility that the Swedish agricultural sector will grow in the future and supply more regions than its own territory with food due to, e.g., climate change. Although appropriate regulations exist to support local decision makers in protecting agricultural land in Sweden, the potential to provide such protection is not fully utilised. This paper aims to contribute to explaining why Swedish municipalities build on agricultural land through an analysis of the values behind the arguments for preserving and exploiting agricultural land at the municipal level and the implications of these values for the preservation of agricultural land in Sweden. Assuming value pluralism, we analyse 30 municipal comprehensive plans through a framework of nine realms of value. We find that municipalities deploy at least eight of the nine realms of value to motivate the preservation of agricultural land, but the economic realm is more dominant among arguments to exploit agricultural land. Most plans do not consider food security. Municipalities could become better prepared to handle unexpected events if they worked with longer-term future scenarios. Further research is needed regarding how different values are weighed against each other in actual exploitation issues.     

The research cost of adapting agriculture to climate change: A global analysis to 2050

Investments in agricultural research and development (R&D) made over the next few decades will likely prove critical in offsetting adverse climate change impacts on the global food system. In this study, we offer cost estimates of public R&D-led adaptation to climate change grounded in an explicit framework relating the flow of annual R&D expenditures to building knowledge capital and thereby raising productivity in agriculture. Our research uses a comprehensive collection of historical public agricultural R&D expenditure and a literature review of elasticity estimates linking knowledge stocks to agricultural productivity growth for key world regions. Given climate-driven crop yield projections generated from extreme combinations of crop and global circulation models, we find that offsetting crop yield losses projected by climate and crop models over 2006–2050 would require increased R&D adaptation investments of between $187 billion and $1,384 billion (in 2005 $PPP) if we invest between 2020 and 2040. This is 16–118% higher than global R&D investment if present spending trends continue. Although these costs are significant, worldwide R&D-led climate adaptation could offer favorable economic returns. Moreover, R&D-led adaptation could deliver gains in food security and environmental sustainability by mitigating food price increases and slowing cropland expansion.     

Causal chains,policy trade offs and sustainability: Analysing land (mis)use in seven countries in the South

The need to enhance sustainable development of land use is more urgent than ever; specifically in developing countries where poverty and land degradation are often interlinked. To promote a common understanding of land use problems by experts, stakeholders and decision makers, it is essential to understand the system characteristics, including the complex feedbacks between drivers and impacts. To enhance sustainable development, appropriate policies need to be identified. In this paper, we analysed and compared seven case studies in Kenya, Mali, Tunisia, China, India, Indonesia and Brazil, representing different biophysical and socio-economic conditions and challenges. We analysed Driver Pressure State Impact Response (DPSIR) story lines of the land use problems, policy priorities and value trade-offs as identified by stakeholders and experts in National Policy Forums. Important drivers of land use change impacting main land use problems among the case studies were economic growth, technological development, immigration and agricultural intensification, in addition to existing policies. Of the latter the most important were related to domestic support through various forms of subsidies or access to credit, land tenure polices and liberalization policies. In the policy prioritization, the value trade-offs made by the National Policy Forums emphasize the environment rather than increased economic production. It is recognized that the environment needs to be improved to maintain and improve economic production in the long term, both in agriculture and in other sectors.     

The Impact of Seed Policy Reforms and Intellectual Property Rights on Crop Productivity in India

The growth of private investment in developing‐country agriculture, new advances in the biological sciences, and rapid integration of developing countries into the global trading system has heightened interest in the topic of seed market and intellectual property rights’ (IPRs) policies among public policy‐makers, corporate decision‐makers and other actors in the agricultural sector. But there are still unanswered questions about whether emerging and evolving seed policy reforms and IPR regimes in developing countries will contribute to increasing crop productivity and improving food security. This paper attempts to answer some of these questions by focusing specifically on the case of India, the regional leader in implementing seed policy reforms and IPRs in agriculture. Findings indicate that maize and pearl millet yields grew significantly during the last two decades due partly to the combination of (1) public policies that encouraged private investment in India’s seed industry during the 1980s, and (2) biological IPRs conferred by hybridisation that conveniently married the private sector’s need for appropriability with the nation’s need for productivity growth. Although past lessons are not an indication of future success, this convergence of policy solutions and technology opportunities can be replicated for other crops that are vital to India’s food security.

Agriculture and development: revisiting the policy narratives

This essay questions the way the findings from research on agriculture in poor countries tend to be summarized in policy narratives, and more specifically the role agricultural economics tends to play in this process. I conclude that there is a tendency to overstate the role agriculture plays in development and, as a result, some of the wrong battles are being fought in the policy advocacy arena, and inappropriate advice is being offered to policy makers. A more open and self‐critical approach to the place of agriculture in development would be more helpful for policy design.     

新冠肺炎疫情冲击粮食安全:趋势、影响与应对

新冠肺炎疫情在全球加速扩散蔓延,引发全球粮食市场异常波动以及对中国粮食安全的担忧。疫情对后期全球粮食生产与贸易的影响将进一步加大,全球粮食市场波动有可能进一步升级。随着全球金融市场充分释放流动性,国际投机资本若炒作农产品市场,爆发类似2008年粮食危机的风险将越来越高。分析表明,中国粮食安全保障体系总体上可从容应对全球粮食市场波动升级的挑战,但大豆等农产品进口需防控国际市场波动风险。本文认为,要高度重视全球粮食市场波动的可能风险和挑战,必须加强监测、及早谋划,系统应对、综合施策。包括:有效管控输入性不稳定预期对国内粮食市场的干扰和冲击;进一步强化粮食生产能力建设;构建国家粮食安全保障风险治理体系;完善重要农产品储备体系;强化农产品全球供应链管理;加强国际粮食安全、贸易和投资政策协调。     

ESTIMATION OF SOCIAL WELFARE WEIGHTS IN AGRICULTURAL POLICY: THE CASE OF GREEK COTTON

This paper provides a welfare analysis of the Greek cotton market and obtains an estimate of the distributional weights implicit in the postulated welfare function of agricultural policy makers. The estimate of that weight depends, as might be expected, on the elasticity of supply and the difference between the support price and the market price. For the period covered, the welfare of Greek cotton producers was weighted about ten per cent more than that of taxpayers.     

Challenges and policy options in the global bio‐economy: introduction and overview

Agricultural economics is at the nexus of the major policy options surrounding the global bio‐economy. The outputs from agriculture have expanded beyond the traditional food, feed, and fiber to include fuel and other nonfood applications as well as environmental goods due to recent technological developments and changing consumer demands. Numerous policy questions have arisen within the bio‐economy. This article introduces and summarizes several invited panel sessions on issues of special importance in the global bio‐economy: new institutions of dealing with uncertainty and increased volatility related to climate change; structural transformations in agricultural production and food consumption and their effect on development; biofuel policies and development; and determinants of changes in consumer attitudes to new products and technologies.     

Public agricultural R&D over the past half century: an emerging new world order

Recent trends in farm productivity and food prices raise concerns about whether the era of global agricultural abundance is over. Agricultural R&D is a crucial determinant of agricultural productivity and production, and therefore food prices and poverty. In this article, we present entirely new evidence on investments in public agricultural R&D worldwide as an indicator of the prospects for agricultural productivity growth over the coming decades. The agricultural R&D world is changing, and in ways that will definitely affect future global patterns of poverty, hunger, and other outcomes. The overall picture is one in which the middle‐income countries are growing in relative importance as producers of agricultural innovations through investments in R&D, and have consequently better prospects as producers of agricultural products.     

Human behavior and the use of experiments to understand the agricultural,resource, and environmental challenges of the XXI century

The use of laboratory¹ experiments in economics, and their later deployment in the field as a tool for exploring how actual decision‐makers respond to information, incentives or institutions has brought a revolution to how we model economic systems, and design policies for them. This new century will bring challenges for the study of agriculture, natural resources and the environment, where it will be necessary to have a better understanding of human behavior, in a world where climate on the one hand, and land, labor and food markets are ever more unstable. This article reviews the intellectual history of a rich dialogue between theory and experiments with a particular focus on its relevance for agricultural, resource and environmental issues. Special attention will be given to the case of common‐pool resources where this dialogue between models, field work and laboratory experiments continues to provide a rich cross‐fertilization for the advance in the understanding of the economic systems that governs these resources. I will close by arguing that agricultural, environmental and resource economists will have to take part of this behavioral revolution by embracing experiments in their teaching, their research and their policy design.     

Global food demand,productivity growth,and the scarcity of land and water resources: a spatially explicit mathematical programming approach

In the coming decades, an increasing competition for global land and water resources can be expected, due to rising demand for food and bio‐energy production, biodiversity conservation, and changing production conditions due to climate change. The potential of technological change in agriculture to adapt to these trends is subject to considerable uncertainty. In order to simulate these combined effects in a spatially explicit way, we present a model of agricultural production and its impact on the environment (MAgPIE). MAgPIE is a mathematical programming model covering the most important agricultural crop and livestock production types in 10 economic regions worldwide at a spatial resolution of three by three degrees, i.e., approximately 300 by 300 km at the equator. It takes regional economic conditions as well as spatially explicit data on potential crop yields and land and water constraints into account and derives specific land‐use patterns for each grid cell. Shadow prices for binding constraints can be used to valuate resources for which in many places no markets exist, especially irrigation water. In this article, we describe the model structure and validation. We apply the model to possible future scenarios up to 2055 and derive required rates of technological change (i.e., yield increase) in agricultural production in order to meet future food demand.     

Going green in Thailand: Upgrading in global organic value chains

Under what conditions are some small-scale agricultural producers able to overcome challenges associated with shifting to organic production, whereas most are not? The answers are vital for the global effort to encourage more sustainable, pro-poor forms of agriculture—more organic farming, more sustainable production; more smallholders engaged in green production, more income and better livelihoods. Yet, answering this question is challenging in part because previous analyses of global production networks, such as those associated with organic agriculture, focus more on broad governance patterns than the specific factors and actors that help smallholders shift to organic production and link to far-flung markets. To fill in these gaps, we conducted fieldwork in Isan, Thailand, a major rice-producing area in which many groups of smallholders have attempted to shift into organic production. Doing so allows us to identify the critical challenges associated with upgrading into organic production and analyse how specific actors enabled some groups to overcome these challenges. Our findings provide a generalizable theoretical approach to understanding how to link small-scale farmers to global value chains in ways that can potentially enhance smallholders' livelihoods, spark rural development and encourage more sustainable practices in agriculture.     

Governing by models: Exploring the technopolitics of the (in)visilibities of land

Achieving food security at a global scale while protecting the environment, as envisioned in the Sustainable Development Goals, will require a complex process of collaboration and the integration of analyses at multiple scales. Agricultural and land use models are increasingly being used to bridge the global/local divide, particularly as a means to envision future land access, use and management in different agricultural production systems. This special issue contributes to our understanding of global modeling, governance and land use change. Specifically, it provides insights into the question of: how do the ways of knowing and governing affect the politics of environmental protection and agriculture? The papers in this special issue bring reflexive questions of knowledge production, public policy and civic engagement into the epistemic spaces of scientific and technological development, both as a means to improve the way we model and to understand the implications of governing by models.     

Development of agriculture in Ethiopia since the 1975 land reform

A stated objective of the Ethiopian Government since it came to power in 1975 has been to increase the production of crops for both domestic consumption and export. Consequently, a number of plans and programs have been proposed and implemented to bring about such development in Ethiopian agriculture. This paper mainly focuses 011 a macro review of the general course of Ethiopian agricultural development since the land reform of 1975. The food production in Ethiopia has lagged behind the population growth as evidenced by the gap between the growth rates of population (3%) and food production (1.8%) over the period from 1970 to 1983. Recently, this situation has, perhaps, further deteriorated. Seventy-one percent of the total land mass is estimated to be suitable for agriculture, but only about 19% is cultivated. This suggests an underutilisation of land. Moreover, Ethiopia has a persistent subsistence production problem in agriculture. Agricultural research and education which are essential to development have not been given due attention by the policy makers. As a result, the agricultural technologies used by farmers have changed little in this century. Moreover, small-scale farmers, although still the most potent economic force in the country, have not been given the incentives necessary to expand production, and currently receive less than adequate support from the central government. Some 85%, 50%, and 79% of total agricultural credit, fertiliser and improved seeds respectively go directly to socialist enterprises (state farms and producers' cooperatives) which, up to 1985, have jointly accounted for only 5% of the total cultivated land and 4% of the national crop production. The favouring of large-scale and capital-intensive state-owned farming enterprises with credit, subsidies, and fiscal incentives, while neglecting smallholders, has contributed to the stagnation of agricultural production in Ethiopia. Overall, the analysis indicates that there has been no significant development of agriculture in Ethiopia following the 1975 land reform.     

Market intermediaries,storage and policy reforms

Intermediaries play a crucial role in the functioning of agricultural and food markets in developing countries through linking production, imports and storage with consumption. We analyse how competition in the intermediary sector and alternative forms of intermediaries determine the incentives for storage and market outcomes more generally. We apply this framework to the Egyptian wheat sector as an illustrative case study, a country where food security is a priority, where both forms of intermediaries co-exist and undertake storage but where issues of reforms to the role of intermediaries have been raised. Through stochastic simulation, we analyse two changes in government policy: first, the effects of changing the policy instruments with both types of intermediaries undertaking storage; second, relating to market reforms where the private sector replaces the storage function of the parastatal. These issues have wider significance for addressing the interaction between food security and a wide range of policy reforms including de-regulation of parastatals in developing countries.     

日本与欧美农业环境支持政策对中国的启示

农业政策中与环境相关的支付政策越来越多。发达国家将WTO绿箱政策、农业直接支付政策与农业环境支持政策结合起来,这样既可以从根本上解决农业生产所带来的安全问题,也可以加深消费者对相关政策的理解与支持,同时从产业链的上游解决食品安全及农业的可持续发展问题。欧盟的Greening政策和日本实施的农业直接支付政策均以农户遵守农药化肥及农业废弃物处理的相关规范为前提,通过合理使用肥料及各种防治措施从不同程度上达到农业可持续发展、农业的多功能性及降低温室气体排放的目的,并由此获取政府的支持。文章通过对发达国家,特别是与中国农业形态类似的日本农业环境政策取向的分析及与欧美相关政策比较分析,认为中国首先应该完善循环农业的相关法律法规和标准,加强对农民的培训以及明确其应遵守的基本义务,对采取环境友好型农业生产方式的农民给予支持。     

An analysis of industrial–agricultural interactions: a case study in Pakistan

This paper empirically analyzes the relationship between Pakistan's industrial and agricultural sectors. Pakistan was chosen because of its status of a semi‐industrialized country with heavy dependence on the agricultural sector. The relationship between cotton production and industrial growth is also evaluated due to the prominence of this crop in Pakistani agriculture. The results indicate that these sectors are complementary, yet industry tends to benefit more from agricultural growth than vice versa. The timing of this information is critical, as Pakistan's policy makers now face major agricultural policy reforms in their quest for continued industrial development.
