Adopting a food systems approach
Meeting the challenge

While elements of GEC are allied closely to food production practices, food insecurity is not simply a problem of supply. The world currently produces sufficient food for all, but it is distributed unequally according to resources and wealth as well as changing patterns of supply and demand (see box). However, meeting demand (as expressed by markets) will not address the food needs of the poor; the food-insecure remain so largely because their incomes are too low or prices are too high. The likelihood of increasing food price volatility will continue to affect the poorest more than most. Furthermore, many vulnerable parts of the world remain in the grip of poor governance and conflict, which undermine physical, social and economic access to food.
GEC further compromises food security for those already prone to hunger because it affects all aspects of food security, i.e., the stability of food availability, access and use. Those whose livelihoods are bound closely with food production and who have low coping capacity are most vulnerable to the effects of GEC, which may include crop failure, attack from pests and diseases, and water shortage. In the short term, climate change will affect food security through more frequent and intense episodes of extreme weather, while longer-term effects include changing patterns of rainfall and temperature as well as soil degradation and biodiversity loss. At the same time, people across the globe may face rising food prices in the absence of a production response to increased demand, disease outbreaks and crises of water management, together with broader impacts on local and national economies.
While there is scope to increase global food production, future approaches and technologies must be based on sustainable approaches to intensification, with the public goods provided by natural ecosystems (e.g., water and carbon storage) taken into account wherever possible. The complex interactions within and between the food system, natural resources and socioeconomic factors mean that close coordination among multiple sectors is vital. Stronger links must be forged between sectors relating to agriculture, fisheries, environment, trade, energy, transportation, marketing, health and consumer goods. In taking forward action agreed internationally, including through the G20 Action Plan, countries should adopt a sustainable and integrated approach to promoting improvements in productivity. This implies adopting a particular research focus on key crops, including those most relevant for vulnerable countries and populations.
A more joined-up approach should involve integrated analyses of food, climate, environment, population and socio-economic systems. The results will guide cross-sectoral decision making and the integrated responses needed to address food security and support sustainable and resilient livelihoods for future generations.


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) 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.

A resilient food system:
An equitable food system:
Food systems are becoming increasingly complex, with multiple interactions at several levels on a range of spatial, temporal and other scales. They are dependent on and influence biogeochemical and socioeconomic processes. Their high dependence on energy and water requires ever-closer coordination between practice and policy for these sectors, as well as with sectors responsible for the environment, trade and transportation, marketing and consumption. 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, 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 nongovernmental organizations must be included in future decision making.

Food systems involve:
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.

Producing food: natural resources, inputs, markets . . .
Processing and packaging food: raw materials, standards, storage requirements . . .
Distributing and retailing food: transport, marketing, advertising . . .
Consuming food: acquisition, preparation, customs . . .



The route to more sustainable food systems and economies takes many different paths and includes more sustainable use of energy and patterns of consumption, as well as sustainable intensification of food production. Agroecological approaches based on a range of technologies and levels of production, improved food systems understanding and enhanced management will play important roles. Poverty reduction and greening of the economy must be regarded as complementary not competing goals, since sustainable food systems protect the assets on which the livelihoods of the poor depend. Enabling policies and institutions are therefore needed to support the creation of real opportunities for economic development among poor communities.
The challenges of food security, natural resource use and GEC call for countries to renew their efforts to work together in the management of global public goods. This includes greater cross-system coherence and integrated planning across institutional frameworks. New institutional arrangements are needed to promote cooperation between public and private investors in food systems and to recognize the rapidly expanding role of nonstate actors. Finally, institutions must adopt a more flexible approach to encourage more equitable and sustainable consumer choice. This will require enhanced food system governance, since poor governance and conflict are among the key drivers of food insecurity.
