The potential impacts of climate change on maize production in Africa and Latin America in 2055
TLDR

The impacts of climate change on agriculture may add significantly to the development challenges of ensuring food security and reducing poverty. We show the possible impacts on maize production in Africa and Latin America to 2055, using high-resolution methods to generate characteristic daily weather data for driving a detailed simulation model of the maize crop. Although the results indicate an overall reduction of only 10% in maize production to 2055, equivalent to losses of $2 billion per year, the aggregate results hide enormous variability: areas can be identified where maize yields may change substantially. Climate change urgently needs to be assessed at the level of the household, so that poor and vulnerable people dependent on agriculture can be appropriately targetedin research andd evelopment activities whose object is poverty alleviation. r 2003 Elsevier Science Ltd.

TL;DR: Uncertainties related to the representation of carbon dioxide, nitrogen, and high temperature effects demonstrated here show that further research is urgently needed to better understand effects of climate change on agricultural production and to devise targeted adaptation strategies.

TL;DR: In this paper, the authors examine the evidence on the economic impacts of climate change itself, and explore the economics of stabilizing greenhouse gases in the atmosphere, concluding that the benefits of strong, early action on climate change considerably outweigh the costs.

Robust negative impacts of climate change on African agriculture
TL;DR: In this article, the authors show that by combining historical crop production and weather data into a panel analysis, a robust model of yield response to climate change emerges for several key African crops, including maize, sorghum, millet, groundnut, and cassava.
Journal ArticleDOI
The impact of climate change on smallholder and subsistence agriculture.
TL;DR: Some recent work relevant to these farming systems is reviewed, a conceptual framework for understanding the diverse forms of impacts in an integrated manner is proposed, and future research needs are identified.

Potential impact of climate change on world food supply
TL;DR: 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 crop production.
