Climate Change Impacts on Global Food Security

  title={Climate Change Impacts on Global Food Security},
  author={T. R. Wheeler and Joachim von Braun},
  pages={508 - 513}
Climate change could potentially interrupt progress toward a world without hunger. A robust and coherent global pattern is discernible of the impacts of climate change on crop productivity that could have consequences for food availability. The stability of whole food systems may be at risk under climate change because of short-term variability in supply. However, the potential impact is less clear at regional scales, but it is likely that climate variability and change will exacerbate food… Expand
Food Security and Climate Change
Climate change may potentially disrupt progress toward a world without hunger. Today, a clear and consistent global pattern is perceptible of the different impacts of climate change on cropExpand

The stability of global, national, and local food systems is at risk under climate change. Climate change affects food production, availability of and access to food, food quality, food safety, dietExpand
Climate change and food security: a Sri Lankan perspective
There is growing concern in Sri Lanka over the impact of climate change, variability and extreme weather events on food production, food security and livelihoods. The link between climate change andExpand
Food security outcomes under a changing climate: impacts of mitigation and adaptation on vulnerability to food insecurity
Climate change is a potential threat to achieving food security, particularly in the most food insecure regions. However, interpreting climate change projections to better understand the potentialExpand
Chinese Food Security and Climate Change: Agriculture Futures
Abstract Climate change is now affecting agriculture and food production in every country of the world. Here the authors present the IMPACT model results on yield, production, and net trade of majorExpand
The impact of population growth and climate change on food security in Africa: looking ahead to 2050
ABSTRACT Providing nutritious and environmentally sustainable food to all people at all times is one of the greatest challenges currently facing society. This problem is particularly acute in AfricaExpand
Food security and climate change from a systems perspective: community case studies from Honduras
Food security is described as a condition in which all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferencesExpand
Climate change, food, water and population health in China
How climate change will affect food, human health and water in China is explored and projections indicate that the overall effects of climate change, land conversion and reduced water availability could reduce Chinese food production substantially. Expand

This is an attempt to provide a review on the relationship between climate change impacts and crop production and emphasizes the role of crop simulation models in achieving food security. Expand
Changing Food Systems: Implications for DFID Priorities
How food systems change over the coming decades will have profound implications for development goals and priorities. Changes in what we eat, population growth, and urbanisation – along with theExpand


Adapting to climate change to sustain food security
Climate change poses considerable challenges to food security. Adapting food systems both to enhance food security for the poor and vulnerable and to prevent future negative impacts from climateExpand
Global food security under climate change
It is found that of the four main elements of food security, i.e., availability, stability, utilization, and access, only the first is routinely addressed in simulation studies, indicating the potential for further negative impacts beyond those currently assessed with models. Expand
Effects of climate change on global food production under SRES emissions and socio-economic scenarios
Abstract This paper analyses the global consequences to crop yields, production, and risk of hunger of linked socio-economic and climate scenarios. Potential impacts of climate change are estimatedExpand
Food Security: The Challenge of Feeding 9 Billion People
A multifaceted and linked global strategy is needed to ensure sustainable and equitable food security, different components of which are explored here. Expand
The poverty implications of climate-induced crop yield changes by 2030
Accumulating evidence suggests that agricultural production could be greatly affected by climate change, but there remains little quantitative understanding of how these agricultural impacts wouldExpand
Potential impact of climate change on world food supply
A global assessment of the potential impact of climate change on world food supply suggests that doubling of the atmospheric carbon dioxide concentration will lead to only a small decrease in globalExpand
Sustainable Intensification in Agriculture: Premises and Policies
Clearer understanding is needed of the premises underlying SI and how it relates to food-system priorities and climate change poses challenges to agriculture. Expand
Predicting the risks from climate change to forage and crop production for animal feed
Climate change is expected to bring warmer temperatures, changes to rainfall patterns, and increased frequency of extreme weather. Projections of climate impacts on feed crops show that there willExpand
Climate change impacts on crop productivity in Africa and South Asia
Climate change is a serious threat to crop productivity in regions that are already food insecure. We assessed the projected impacts of climate change on the yield of eight major crops in Africa andExpand
How will climate change affect mycotoxins in food
The impact of climate change on mycotoxins in food is assessed: only one paper and an abstract referred directly from a substantial literature search and then only in relation to Europe. Expand
