Above all, there is need for astrong focus on resilience, equity and sustainability. This brief sets out broad guidelines to help policy anddecision makers work towards adopting a more coordinated and integrated approach to food security issues.Rio+20 Policy BriefsOne of nine policy briefs produced by the scientific community to inform the United Nations Conference on SustainableDevelopment (Rio+20). These briefs were commissioned by the international conference Planet Under Pressure: NewKnowledge Towards Solutions (www.planetunderpressure2012.net).

However, Those whose livelihoods are bound around one billion people meeting demand (as expressed by closely with food production and do not have enough to eat, markets) will not address the food who have low coping capacity areand a further billion lack adequate needs of the poor; the food-insecure most vulnerable to the effects of GEC,nutrition.

The sustainable and integrated approach needed to address food security andcomplex interactions within and to promoting improvements in support sustainable and resilientbetween the food system, natural productivity. This implies adopting livelihoods for future generations. Changing patterns of supply and demand In addition to continuing population growth, coupled with increasing consumption by a wealthier population in general, three issues are of particular importance in the food security debate: Urbanization and increasing wealth Over half of the world’s population now lives in an urban environment. Where this is associated with increased affluence, it increases consumption expectations, thereby raising food demand per capita and local prices. However, the urban poor spend a large proportion of their income on food and are acutely sensitive to food price fluctuations. Urban development is also eating into prime agricultural land and, in many cities, nutrients are accumulating in waste instead of being returned to agricultural areas. Globalization Growing interconnectedness between food, energy and financial markets can lead to greater volatility in global food prices, sparked by both rising demand and competition for resources. Geographic interconnectedness of food markets per se has however increased food availability internationally and is likely to reduce global food price volatility. But its impact in any given country varies, depending on such market conditions and policy measures as import duties, export taxes and subsidies. In cases where such measures hinder the competitiveness of domestic producers, better market access and information systems are needed to help poor producers take advantage of new and emerging opportunities. Changing consumption patterns As people in the rapidly developing nations (e.g., China) Photo: istockphoto/FOTOVOYAGER become wealthier, they increase demand for processed food, meat, fish and dairy products. Such food often has a larger environmental ‘footprint’ than less processed food, and the larger volumes demanded by more affluent people cause even greater environmental impacts. The changing nature of demand offers both opportunities and threats to farmers, with those having better access to information, resources and markets set to benefit most. Multinational food retailers are becoming more powerful in negotiating prices with farmers and other suppliers. For the rural poor, the key challenge is to match supply and demand across the seasons, which calls for improvements in post-harvest handling, storage and distribution as well as better access to insurance and credit.

This gives rise to substantial institutional complexity, with multiple actors operating within different institutional frameworks. The food systems of the future will therefore need to be based on innovative interdisciplinary research, Photo: istockphoto/SIMON GURNEY enhanced science–policy dialogue, and greater institutional and societal flexibility. Private sector research now dominates technological developments for several key food and feed crops so private and non- governmental organizations must be included in future decision making.
  • 6. 6 What is a food systems approach? Food systems involve: zz a set of activities related to producing, processing, distributing, marketing, preparing and consuming food; and zz the outcomes of these activities contributing to food security (food availability, food access and food utilization, all stable over time) and to other socioeconomic (e.g., wealth) and environmental (e.g., greenhouse gas emissions) issues. A food systems approach systematically connects the activities of food producers, processors, distributors, retailers and consumers involved in food systems with food security and other outcomes. This helps in a number of ways: 1. Providing a checklist to help ensure the necessary issues are included in dialogues aimed at enhancing food security (especially in the context of other goals) and identifying the range of actors and other interested parties who should be involved. 2. Assessing the impacts of GEC on food systems by focusing on multiple vulnerabilities in the context of socioeconomic stresses. 3. Determining the main limiting factors that lead to food insecurity, thereby identifying intervention points for enhancing food security. By systematically connecting the food system activities with the food security and other outcomes, the approach helps unravel the complexity inherent in food systems: it frames the interactions as dynamic and interdependent processes that are embedded in social, political, economic, historical and environmental contexts. Adopting a food systems approach improves understanding of the interactions between food security and environmental or other stresses, thereby clarifying decision making regarding appropriate policy options.
