The impact of including water constraints on food production within a CGE framework
… pasture land, managed forest land, natural grass land and natural forest land-and conversion among these land types. I further develop this framework by describing crop production as the aggregate production of crops grown on irrigated and non-irrigated cropland. Water resources, …

Anthropogenic impacts on recharge processes and water quality in basin aquifers of the desert Southwest : a coupled field observation and modeling study
The development of natural grass/scrubland for agricultural use within the Trans-Pecos basins has altered recharge mechanisms and raised questions about groundwater sustainability. Past efforts focused on recharge in arid basin systems used three main assumptions: there is minimal modern recharge, …

The influence of an umbelliferous understory on the parasites of organic apple orchards in Canterbury
… different orchards were sampled, one with a natural grass understorey, and two with a managed wild parsnip understorey. Adult parasites were trapped using yellow pitfall traps, elevated water traps and aspiration from parsnip inflorescences. 'Delta' pheromone traps were used to trap male …
