This paper investigates the management strategies and responses used by New Zealand sheep and beef farmers to ensure resilience during periods of hardship. Using two, farm level surveys conducted in 1986 and 2010, some aspects of resilient farming systems were identified. Despite apparent...

This paper discusses the economic implications of the preferential trade agreements that New Zealand is currently negotiating, using a computable general equilibrium modelling framework. The New Zealand dairy industry is a particular focus in the results, which come from the GTAP model produced...

Forest carbon is potentially an important income stream for small land owners in Guatemala that would help to cease deforestation and forest degradation pressures. However, the temporary nature of sequestered forest carbon, the risk of environmental disturbances releasing forest sequestered...
