Viewpoint on the role for scientists in tackling food insecurity and climate change

To adapt to climate change and ensure food security, major interventions are required to transform current patterns and practices of food production, distribution and consumption. The scientific community has an essential role to play in informing concurrent, strategic investments to establish climate-resilient agricultural production systems, minimize greenhouse gas emissions, make efficient use of resources, develop low-waste supply chains, ensure adequate nutrition, encourage healthy eating choices and develop a global knowledge system for sustainability. This paper outlines scientific contributions that will be essential to the seven policy recommendations for achieving food security in the context of climate change put forward by the Commission on Sustainable Agriculture and Climate Change. These include improved understanding of agriculture's vulnerability to climate change, food price dynamics, food waste and consumption patterns and monitoring technologies as well as multidisciplinary investigation of regionally appropriate responses to climate change and food security challenges.

The world faces multiple challenges to food security including under nutrition and overconsumption, rising food prices, population growth, rapid diet transitions, threats to agricultural production, inefficient production practices and supply chains, and declining investment in food system research. In addition to causing widespread human suffering, food insecurity contributes to degradation and depletion of natural resources, migration to urban areas and across borders, and political and economic instability.

The food system faces additional pressure as the global population grows to around 9 billion by 2050. This dramatic increase in global population will be accompanied by major shifts in the regional distribution of our planet's inhabitants. From 2010 to 2050, the population in Asia is estimated to grow from 4.2 billion to 5.1 billion and Africa's population to grow from 1 billion to 2.2 billion. From 1950 to 2050, the population ratio for developing countries to developed countries is projected to shift from 2:1 to 6:1.
