Mechanisms of global governance, developed in response to initiatives adopted by the FAO to combat hunger and confront food crises, are the result of wide ranging historical debates using three basic criteria for justification: the scientific, the political‐ideological, and the ethical. On the basis of these criteria, certain forms of understanding and acting on agriculture, health and nutrition at global level have come to be accepted as valid. Currently the debate and the resulting proposals are based on the recognition of food as a universal human right. 相似文献

In mid 2011, the Food and Agriculture Organization (FAO) and World Food Programme (WFP) formally launched the global Food Security Cluster (FSC) as the UN’s global mechanism for coordinating food security responses in emergencies worldwide. The need for greater coordination of food security response in emergencies is enormous: Not only is the number of actors growing ever larger, the operating environment is more complex, and the range of responses requires substantially greater levels of skill than ever in analysis, planning, implementation, and monitoring and evaluation. Will this new mechanism provide the leadership needed for complex, multi-dimensional responses needed to protect food security and livelihoods in disasters? What are the special challenges the cluster faces? This paper analyzes a series of country level case studies and key informant interviews with stakeholders in a range of roles to address these questions. 相似文献

An imaginative American legislation, the Morrill Act of 1862, established the U. S. Land Grant University Model, where such universities would adopt a uniform, tri-partite function of education, research, and extension. It legislated that these universities would provide segments of society with practical and timely education that would be useful to their daily lives. A profound concept based on a system that focused on educating the next generation of agricultural scientists, providing support to the generation of new knowledge and technology, and communicating the results of the new discoveries to key stakeholders was born. Sustained support of this 19th century legislation and the commitment and drive of generations of agricultural scientists and farmers brought about remarkable advances, making 20th century American agriculture most productive and the envy of the world. These successes were replicated in North America, Europe, and in much of the developed world, and served as the impetus for the emergence of the Asian Green Revolution. Farming became a profitable business and consumers were accustomed to safe and relatively inexpensive supply of food, unfortunately leading to 21st century complacency. The recent food price crises seem to have reawakened world leaders and donor agencies to the necessity of assuring the food security of nations and to revitalizing and reinvesting in the agricultural sciences. 相似文献

Since the 2007/08 food price crisis there has been a proliferation of multi-stakeholder processes (MSPs) devoted to bringing diverse perspectives together to inform and improve food security policy. While much of the literature highlights the positive contributions to be gained from an opening-up of traditionally state-led processes, there is a strong critique emerging to show that, in many instances, MSPs have de-politicizing effects. In this paper, we scrutinize MSPs in relation to de-politicization. We argue that re-building sustainable and just food systems requires alternative visions that can best be made visible through politicized policy processes. Focusing on three key conditions of politicization, we examine the UN Committee on World Food Security as a MSP where we see a process of politicization playing out through the endorsement of the ‘most-affected’ principle, which is in turn being actively contested by traditionally powerful actors. We conclude that there is a need to implement and reinforce mechanisms that deliberately politicize participation in MSPs, notably by clearly distinguishing between states and other stakeholders, as well as between categories of non-state actors. 相似文献

Population growth increases the demand for food and thus leads to expansion of cultivated land and intensification of agricultural production. There is a definite limit to both of these options for food security and their multiple negative effects on the environment undermine the aim for sustainability. Presently the impact of the Green Revolution on crop production is levelling off at high yields attained and even the potential of large scale irrigation programmes and transgenic crops seem to be limited in view of the expected increase in demand for food. Moreover, climate change threatens to affect agricultural production across the globe. Skyfarming represents a promising approach for food production that is largely environment independent and therefore immune to climate change. Optimal growing conditions, shielded from weather extremes and pests are aimed at raising plant production towards the physiological potential. Selecting rice as a pioneer crop for Skyfarming will not only provide a staple for a large part of the global population, but also significantly reduce the greenhouse gas emission caused by paddy cultivation. Multiplication of the benefits could be achieved by stacking production floors vertically. In Skyfarming the crop, with its requirements for optimal growth, development and production, determines the system’s design. Accordingly, the initial development must focus on the growing environment, lighting, temperature, humidity regulation and plant protection strategies as well as on the overall energy supply. For each of these areas potentially suitable technologies are presented and discussed. 相似文献

The literature on the importance of plant pathogens sometimes emphasizes their possible role in historical food shortages and even in famines. Aside from such major crises, plant pathogens should also be seen as important reducers of crop performances, with impacts on system sustainability, from the ecological, agronomical, social, and economic standpoints – all contributing ultimately to affecting food security. These views need reconciliation in order to produce a clearer picture of the multidimensional effects of plant disease epidemics. Such a picture is needed for disease management today, but would also be useful for future policies. This article attempts to develop a framework that would enable assessment of the impacts of plant diseases, referred collectively to as crop health, on food security via its components. We have combined three different existing definitions of food security in order to develop a framework consisting of the following six components: (1) Availability. Primary production; (2) Availability. Import - Stockpiles; (3) Access. Physical and supply chain; (4) Access. Economic; (5) Stability of food availability; (6) Utility-Safety-Quality-Nutritive value. In this framework, components of food security are combined with three attributes of production situations: the nature of the considered crop (i.e. food- or non-food), the structure of farms (i.e. subsistence or commercial), and the structure of markets (i.e. weakly organized and local, to strongly organized and globalized). The resulting matrix: [Food security components] × [Attributes of production situations] provides a framework where the impacts of chronic, acute, and emerging plant disease epidemics on food security can be examined. We propose that, given the number of components and interactions at play, a systems modelling approach is required to address the functioning of food systems exposed to plant disease risks. This approach would have application in both the management of the current attrition of crop performances by plant diseases, and also of possible disease-induced shocks. Such an approach would also enable quantifying shifts in disease vulnerability of production situations, and therefore, of food systems, as a result of climate change, globalization, and evolving crop health. 相似文献

During the period 2006–2008, general inflation around the world was pressed upwards by food inflation. An important reason
for concern about the impact of high food prices arises from the fact that the poorest people spend approximately three quarters
of their income on staple foods. In Mexico, meals are based on maize, with tortillas providing much of the caloric intake
in rural areas. Prices of maize along with nearly every agricultural commodity sharply increased creating a global food price
bubble. Using the Household Income and Expenditure National Survey (Encuesta Nacional de Ingresos y Gastos de los Hogares
ENIGH) conducted in 2006 and 2008, it was found that higher prices for maize affected Mexican household living standards and
food security both in urban and rural areas. There is an evident decay in household living standards from year 2006 to year
2008. In regional terms, urban areas are better off than rural areas. The poorest rural and urban households—net buyers of
maize—were the most affected as their budget share on maize increased significantly. However, higher prices provided direct
benefits to maize producers in rural areas at all levels of living. Another effect of higher maize prices was to redistribute
income towards maize producer households in the middle and bottom of the rural income distribution. 相似文献

Recurring food crises endanger the livelihoods of millions of households in developing countries around the globe. Owing to the importance of this issue, we explored recent changes in food security between the years 2004 and 2010 in a rural district in Northeastern South Africa. Our study window spans the time of the 2008 global food crisis and allows the investigation of its impacts on rural South African populations. Grounded in the sustainable livelihood framework, we examined differences in food security trajectories among vulnerable sub populations. A unique panel data set of 8,147 households, provided by the Agincourt Health and Demographic Surveillance System (Agincourt HDSS), allowed us to employ a longitudinal multilevel modeling approach to estimate adjusted growth curves for the differential changes in food security across time. We observed an overall improvement in food security that leveled off after 2008, most likely resulting from the global food crisis. In addition, we discovered significant differences in food security trajectories for various sub populations. For example, female-headed households and those living in areas with better access to natural resources differentially improved their food security situation, compared to male-headed households and those households with lower levels of natural resource access. However, former Mozambican refugees witnessed a decline in food security. Therefore, poverty alleviation programs for the Agincourt region should work to improve the food security of vulnerable households, such as former Mozambican refugees. 相似文献

There is growing concern that satisfying societal demand for food over coming decades will be increasingly challenging. Much
of the debate centres on increasing food production which has always been–and remains–an important strategy to alleviate food
insecurity. However, despite the fact that more than enough food is currently produced per capita to adequately feed the global population, about 925 million people remained food insecure in 2010. Meeting future demand
will be further complicated by deleterious changes in climate and other environmental factors (collectively termed ‘global
environmental change’, GEC). This paper lays out a case for a food systems approach to research the complex food security/GEC
arena and provides a number of examples of how this can help. These include (i) providing a framework for structuring dialogues
aimed at enhancing food security and identifying the range of actors and other interested parties who should be involved;
(ii) integrating analyses of the full set of food system activities (i.e. producing, storing, processing, packaging, trading
and consuming food) with those of the food security outcomes i.e. stability of food access, utilisation and availability,
and all their nine elements (rather than only food production); (iii) helping to both assess the impacts of GEC on food systems
and identify feedbacks to the earth system from food system activities; (iv) helping to identify intervention points for enhancing
food security and analysing synergies and trade-offs between food security, ecosystem services and social welfare outcomes
of different adaptation pathways; and (v) highlighting where new research is needed. 相似文献

Declining global per capita agricultural production and warming oceans threaten food security 总被引:1,自引:0,他引:1
Despite accelerating globalization, most people still eat food that is grown locally. Developing countries with weak purchasing
power tend to import as little food as possible from global markets, suffering consumption deficits during times of high prices
or production declines. Local agricultural production, therefore, is critical to both food security and economic development
among the rural poor. The level of local agricultural production, in turn, will be determined by the amount and quality of
arable land, the amount and quality of agricultural inputs (fertilizer, seeds, pesticides, etc.), as well as farm-related
technology, practices and policies. This paper discusses several emerging threats to global and regional food security, including
declining yield gains that are failing to keep up with population increases, and warming in the tropical Indian Ocean and
its impact on rainfall. If yields continue to grow more slowly than per capita harvested area, parts of Africa, Asia and Central
and Southern America will experience substantial declines in per capita cereal production. Global per capita cereal production
will potentially decline by 14% between 2008 and 2030. Climate change is likely to further affect food production, particularly
in regions that have very low yields due to lack of technology. Drought, caused by anthropogenic warming in the Indian and
Pacific Oceans, may also reduce 21st century food availability in some countries by disrupting moisture transports and bringing
down dry air over crop growing areas. The impacts of these circulation changes over Asia remain uncertain. For Africa, however,
Indian Ocean warming appears to have already reduced rainfall during the main growing season along the eastern edge of tropical
Africa, from southern Somalia to northern parts of the Republic of South Africa. Through a combination of quantitative modeling
of food balances and an examination of climate change, this study presents an analysis of emerging threats to global food
security. 相似文献

The food system faces increasing pressure from dynamic and interactive, environmental, political and socio-economic stressors.
Tackling the complexity that arises from such interactions requires a new form of 'adaptive governance'. This paper provides
a review of various conceptions of governance from a monocentric or politicotechnical understanding of governance through
to adaptive governance that is based in complex adaptive systems theory. The review is grounded by a critique of the existing
institutional structures responsible for food security in South Africa. The current Integrated Food Security Strategy and
tasked governmental departments are not sufficiently flexible or coordinated to deal with an issue as multi-scalar and multidisciplinary
as food security. However, actions taken in the non-governmental sector signal the emergence of a new type of governance.
Apart from an increasing recognition of food security as an issue of concern in the country, there is also evidence of a changing
governance structure including collaboration between diverse stakeholders. We review these governance trends with an understanding
of the food system as a complex adaptive socio-ecological system where actors in the food system self-organize into more flexible
networks that can better adapt to uncertain pressures. 相似文献

Policy conflicts in global food assistance strategies: balancing local procurement and harmonization
Lisa F. Clark 《Food Security》2018,10(1):211-222
Coordinated efforts through multilevel governance are important to addressing global food insecurity by mitigating policy conflicts and working towards meeting collective objectives as effectively and efficiently as possible. While multi-stakeholder efforts to provide nutrition-sensitive food assistance have been met with some degree of success, this paper demonstrates that policy change in one area of food security governance has the potential to have unintended consequences on other components within the governance framework. This paper examines the interactive dynamic of three core components of multilevel governance frameworks for international food assistance, specifically Ready-To-Use Foods (RUF) to treat malnutrition, local-regional procurement (LRP) strategies of raw materials for RUFs and international standards for food safety and quality applicable to finished RUFs. It shows how proposed changes in international standards for RUF food safety and quality may have the potential to complicate existing and future efforts to incorporate locally sourced raw materials like pulses into RUF formulations and may also have unanticipated impacts on long-term food security goals pursued at other levels of decision-making. 相似文献

The integration of smallholders into agricultural value chains is considered an important pathway for raising the welfare of farmers, including their food security. Distinct from literature that has mainly dwelt on smallholder integration in high-value and export-orientated agricultural value chains (AVCs), we focus on domestic, traditional AVCs, which are relevant to the majority of smallholders. Using primary household data from Kilosa and Chamwino districts in rural Tanzania, we examined the nature and extent of smallholder participation in traditional AVC activities and their associated welfare effects, focusing primarily on household food security. Cluster analysis was used to explore different smallholder livelihood activities and the extent of participation in traditional AVCs while propensity score matching and inverse probability weighted regression adjustment approaches were employed to analyze food security effects of various AVC activities. Results revealed that smallholders participate at varying levels in different AVC activities and their integration in traditional AVCs plays an important role in improving food security. Whereas other studies analyze only the impacts of participation in single AVC activities, we show the relevance of assessing the effects of multiple AVC activities on food security. Findings highlight the importance of promoting policies that enable effective vertical and horizontal integration of smallholder farmers into traditional AVC activities for enhanced food security and improved livelihoods. 相似文献

Wild meat or ‘bushmeat’ has long served as a principal source of protein and a key contributor to the food security of millions of people across the developing world, most notably in Africa, Latin America and Asia. More recently, however, growing human populations, technological elaborations and the emergence of a booming commercial bushmeat trade have culminated in unprecedented harvest rates and the consequent decline of numerous wildlife populations. Most research efforts aimed at tackling this problem to date have been rooted in the biological disciplines, focused on quantifying the trade and measuring its level of destruction on wildlife and ecosystems. Comparatively little effort, on the other hand, has been expended on illuminating the role of bushmeat in human livelihoods and in providing alternative sources of food and income, as well as the infrastructure to make these feasible. This paper aims to shift the focus to the human dimension, emphasising the true contributions of bushmeat to food security, nutrition and well-being, while balancing this perspective by considering the far-reaching impacts of overexploitation. What emerges from this synthesis is that bushmeat management will ultimately depend on understanding and working with people, with any approaches focused too narrowly on biodiversity preservation running the risk of failure in the long term. If wildlife is to survive and be utilised in the future, there is undoubtedly a need to relax adherence to unswerving biocentric or anthropocentric convictions, to appreciate the necessity for certain trade-offs and to develop integrated and flexible approaches that reconcile the requirements of both the animals and the people. 相似文献

以化肥、农药、机械、单一种植-“四大支柱”为格局的现代农业造成的食物单一化,膳食中营养物质的不平衡,食品中营养元素的贫瘠化,对人类健康造成了严重的影响,这引起了世界各国的普遍重视。现在,发达国家已充分认识到耗能型化学农业的危害,正向传统的东方“生态”型农业转变。即利用自然条件,使用有机肥料,不施任何化肥、农药和人工合成激素,并使用生物农药和害虫的“天敌”杀虫,从而生产出接近天然植物的无污染、无公害的“绿色食品”。增强食物的营养保健 性和提高食物的安全性是21世纪食品工业发展的两个重要趋势。然而在我国从食品生产、加工、销售等一系列环节都存在食品安全隐患,必须引起高度重视。 相似文献
