Food systems contribute 19%–29% of global anthropogenic greenhouse gas (GHG) emissions, releasing 9,800–16,900 megatonnes of carbon dioxide equivalent (MtCO2e) in 2008. Agricultural production, including indirect emissions associated with land-cover change, contributes 80%–86% of total food system emissions, with significant regional variation. The impacts of global climate change on food systems are expected to be widespread, complex, geographically and temporally variable, and profoundly…

Food availability is when all people have sufficient quantities of food available on a consistent basis. Food availability is determined by food production and food trade. Climate change is a

Critical Research Needs for Successful Food Systems Adaptation to Climate Change

There is a growing sense of the fragility of agricultural production in the Global North and South and of increasing risks to food security, as scientific observations confirm significant changes in

Food systems are responsible for a third of global anthropogenic GHG emissions

We have developed a new global food emissions database (EDGAR-FOOD) estimating greenhouse gas (GHG; CO2, CH4, N2O, fluorinated gases) emissions for the years 1990–2015, building on the Emissions

Mapping and linking supply- and demand-side measures in climate-smart agriculture. A review

Climate change and food security are two of humanity’s greatest challenges and are highly interlinked. On the one hand, climate change puts pressure on food security. On the other hand, farming


Climate change is emerging as a major threat on agriculture, food security and livelihood of millions of people in many places of the world Climate-smart agriculture (CSA) is an integrative approach

Options for keeping the food system within environmental limits

A global model finds that the environmental impacts of the food system could increase by 60–90% by 2050, and that dietary changes, improvements in technologies and management, and reductions in food loss and waste will all be needed to mitigate these impacts.

Greenhouse Gas Mitigation under Agriculture and Livestock Landuse

Ensuring food security for the growing global population and changing climate are the principal challenges of the modern agriculture. The global population is projected to reach 9.7 billion by 2050.



Climate Change: Impact on Agriculture and Costs of Adaptation

"The Challenge The unimpeded growth of greenhouse gas emissions is raising the earth’s temperature. The consequences include melting glaciers, more precipitation, more and more extreme weather

The Climate Change and Economic Impacts of Food Waste in the United States

This study analyzes the climate change and economic impacts of food waste in the United States. Using loss-adjusted national food availability data for 134 food commodities, it calculates the

Climate change , plant diseases and food security : an overview

Global food production must increase by 50% to meet the projected demand of the world’s population by 2050. Meeting this difficult challenge will be made even harder if climate change melts portions

Assessment of Energy Use and Greenhouse Gas Emissions in the Food System : A Literature Review

Amid growing concerns about climate change and long-term petroleum reserves, the food system looms large as a major user of fossil fuels and, as a result, producer of greenhouse gases (GHG). Indeed,

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 climate

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.
