Assessment // Responding to Global Challenges in Food, Energy, Environment and Water: Risks and Options Assessment for Decision-Making
R. Quinton Grafton et al. In this article, the authors address what they believe to be the critical obstacle to accomplishing the sustainable development goals that will frame the global agenda in the coming decades: ensuring that global food security is equitably achieved for a much larger projected population, without causing a cascade of negative impacts on the water, energy, climate, land and environmental systems needed to support food production.
The authors analyse the threats of global environmental change, as they relate to food security.
First, three discourses are reviewed:
- (i) "sustainable intensification", or the increase of food supplies without compromising food producing inputs, such as soils and water;
- (ii) the "nexus" that seeks to understand links across food, energy, environment and water systems; and
- (iii) "resilience thinking" that focuses on how to ensure the critical capacities of food, energy and water systems are maintained in the presence of uncertainties and threats.
