Climate change and sustainable food production

CLIMATE CHANGE AND FOOD PRODUCTION by Tim Curtin (Australia) CLIMATE CHANGE AND FOOD PRODUCTION

The availability of atmospheric carbon dioxide is the sine qua non for all plant growth and thence for all marine and terrestrial life forms. The purpose of this paper is to show that proposed reductions in anthropogenic emissions of carbon dioxide (CO2) to below the level of observed annual incremental biospheric absorption of those emissions would reduce the growth of the basic feedstock of a...

Effects of climate change on sustainable food and nutrition security

Sustainable Development and Climate Change

Sustainability is defined in terms of four overlapping positions, ranging from very weak to very strong sustainability. The core idea is of a non-declining capital stock (including natural capital) over generational time. Weak sustainability positions emphasise capital substitution possibilities and the power of technical process to mitigate resource depletion and pollution problems. Climate ch...

Climate Change, Food Security, and Agrobiodiversity: Toward a Just, Resilient, and Sustainable Food System

Food, livestock production, energy, climate change, and health.

Food provides energy and nutrients, but its acquisition requires energy expenditure. In post-hunter-gatherer societies, extra-somatic energy has greatly expanded and intensified the catching, gathering, and production of food. Modern relations between energy, food, and health are very complex, raising serious, high-level policy challenges. Together with persistent widespread under-nutrition, ov...
