This article reviews the potential impacts of climate change on food security. 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. To this end, published results indicate that the impacts of climate change are significant, however, with a wide projected range (between 5 million and 170 million additional people at risk of hunger by 2080) strongly depending on assumed…

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 crop

Climate Change and Food Security in Kenya

The paper investigates the effects of climate change on food security in Kenya. Fixed and random effects regressions for food crop security are estimated. The study further simulates the expected

This chapter will aim to explicate the challenges posed by global warming or the climate change conditions on food security especially from the point of view of India. The negative impact of global

Potential Impact of Climate Change on Food Security

In view of the fact that climate-related disasters are already taking a heavy toll, causing massive damage to crops and infrastructure and forcing some people to flee their homes, however, the

Climate Change and Food Security: Threats and Adaptation

Abstract Food security is at risk from climate change. In fact, climate change and its drivers already affect food production through increased temperatures, changed precipitation patterns, extreme

A multi-model assessment of food security implications of climate change mitigation

Holding the global increase in temperature caused by climate change well below 2 °C above pre-industrial levels, the goal affirmed by the Paris Agreement, is a major societal challenge. Meanwhile,

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 Africa


Climate change is posing a threat on present and future food security in low income countries. But, the actual effect of the climate change on food security is not known. Using secondary data

The impact of climate change on food security in South Africa: Current realities and challenges ahead

It is found that climate change, particularly global warming, affects food security through food availability, accessibility, utilisation and affordability, and there is a need for an integrated policy approach to protect the arable land against global warming.

Does climate change only affect food availability? What else matters?

Abstract This paper reviews the studies from various disciplines and countries on the impacts of climate change on food security and its four dimensions, namely food availability, accessibility, food



Climate change, global food supply and risk of hunger

The main conclusions are: the region of greatest risk is Africa; the impact of climate change on risk of hunger is influenced greatly by pathways of development; and a SRES B2 development pathway is characterized by much lower levels of risk than A2; and this is largely explained by differing levels of income and technology.

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 global

The Consequences of CO2 Stabilisation for the Impacts of Climate Change

This paper reports the main results of an assessment of the global-scale implications of the stabilisation of atmospheric CO2 concentrations at 750 ppm (by 2250) and 550 ppm (by 2150), in relationto

Crop and pasture response to climate change

The links between fundamental knowledge at the plant and plot level and the additional socio-economic variables that determine actual production and trade of food at regional to global scales are critically analyzed.

World Agriculture and Climate Change: Economic Adaptations

Recent studies suggest that possible global increases in temperature and changes in precipitation patterns during the next century will affect world agriculture. Because of the ability of farmers to

Effects of Greenhouse Gas Emissions on World Agriculture, Food Consumption, and Economic Welfare

Because of many uncertainties, quantitative estimates of agriculturally related economic impacts of greenhouse gas emissions are often given low confidence. A major source of uncertainty is our

World agriculture and climate change: Economic adaptations. Agriculture economic report

Recent studies suggest that global increases in temperature and changes in precipitation patterns during the next century will affect world agriculture. Because farmer adaptations, however, these

It is considered unlikely that climate change will lead to an increase in disease linked to mains drinking water, although private supplies would be at risk from increased heavy rainfall events, and increased temperature could lead to climatic conditions favourable to increases in certain vector-borne diseases.
