In Afghanistan, where 80% of the population is rural, irrigated agriculture using surface water is an extremely important economic activity. With the advent of the New Water Law, highly localized and centuries-old agricultural water management traditions are giving way to more modern centralized...

We review the disease ecology and bioeconomic literature on managing wildlife disease problems, and we also describe how wildlife disease problems relate to other health and resource problems. The disease ecology literature advocates managing populations relative to fixed ecological thresholds...

Bioeconomic analyses of predator–prey systems examine how to adjust species management in response to predation spillovers to avoid inefficiencies. Predation spillovers refer to the net economic value of predation, taking into account the impacts on prey. Inefficiencies arise when the species...

Pathogens are a significant driver of biodiversity loss. We examine two wildlife disease management strategies that have seen growing use, sometimes in combination: (i) trapping-and-culling infectious animals (disease control), and (ii) trapping-and-translocating healthy animals to a reserve,...
