Griskevicius, V., Tybur, J. M., & Van den Bergh, B. (in press). "Going green to be seen: Status, reputation, and conspicuous conservation." Journal of Personality and Social Psychology.

The OECD has published a new report called Sustainable Management of Water Resources in Agriculture. Agriculture is the major user of water in most countries. It also faces the enormous challenge of producing almost 50% more food by 2030 and doubling production by 2050. This will likely need to be achieved with less water, mainly because of growing pressures from urbanisation, industrialisation and climate change.
