Wood borers and bark beetles are among the most serious forest pests worldwide. Many such species have become successful invaders, often causing substantial, costly damages to forests. Here we design and evaluate the cost-efficiency of a trap-based surveillance program for early detection of...

This paper assesses the tradeoff between non-farm income and on-farm soil and water conservation investment by smallholder farmers in the semi-arid tropics of India using a dynamic bioeconomic model. This modeling approach allows understanding the complex interaction and feedback between...

Biological control of pests is an important ecosystem service in agricultural landscapes as it protects crops and reduces the need for insecticide use. Establishing a sustainable bioenergy industry requires considering the role of biological control in farm decision making. An important question...

The New Zealand Ministry of Fisheries constrains the incidental capture of Hooker’s sea lions in trawl nets of the southern squid fishery by closing the season once an upper limit on sea lion deaths is reached. The regulatory measure is in fact a limit on effort because the number of sea lion...

Implications of increasing labour cost and development of herbicide resistance for profitable weed management in Philippine rice farming systems are investigated. The study employs RIMPhil (Resistance and Integrated Management in the Philippines), a bioeconomic simulation model developed to...

Virgin nature, as well as historical and cultural monuments located in National Parks, all form part of our national heritage. Tourism and recre- ation allow visitors to National Parks to enjoy nature, to reinstate, recover and broaden their personal outlook, to experience local history,...

This paper develops a bioeconomic model that captures the underlying incentives driving the serial depletion of pristine seamounts. The determinants under New Zealand's Quota Management System relate to unit cost savings from bottom trawling for orange roughy on seamounts, where catch rates are...
