While agriculture accounts for an estimated 10 to 14 percent of total greenhouse gas emissions, its role as a mitigating force is receiving increasing attention.

Early studies on the potential impacts of climate change indicated that agriculture was not likely to be severely affected, as carbon fertilization and trade flows were thought to be able to compensate for any productivity declines related to climate change. Recent work, however, has raised doubts about whether carbon fertilization laboratory test results can be replicated in the field.

This paper analyzes the vulnerability of South African farmers to climate change and variability by developing a vulnerability index and comparing vulnerability indicators across the nine provinces of the country. Nineteen environmental and socio-economic indicators are identified to reflect the three

This study investigates the impact of different soil and water conservation technologies on the variance of crop production in Ethiopia to determine the risk implications of the different technologies in different regions and rainfall zones.

Over the coming decades, global change will have an impact
on food and water security in significant and highly uncertain
ways, and there are strong indications that developing countries
