In this paper, a bioeconomic model is used to investigate possible externalities imposed by forestry on giant-clam farming in Solomon Islands. This is of economic interest due to the rapid expansion of forestry in that country and the potential for mariculture to become an important source of...

The focus of this paper is the role of farm forestry in farming systems in the NSW wheatsheep zone. The wheat-sheep zone suffers from significant land degradation problems, and the environmental and economical sustainability of many farming systems is in question. Farm forestry provides the...

In many areas of developing countries, economic and institutional factors often combine to give farmers incentives to clear forests and repeatedly plant food crops without sufficiently replenishing the soils. These activities lead to large-scale land degradation and contribute to global warming...

The emission of greenhouse gases, particularly carbon dioxide, and the consequent potential for climate change are the focus of increasing international concern. Temporary land-use change and forestry projects (LUCF) can be implemented to offset permanent emissions of carbon dioxide from the...

The issue of deriving benefits from the fishery resource on a sustainable basis exists in most developing countries. This tends to create a major problem confronting both biologists and economists in managing the fishery. In respose to this issue, this paper explains one possible method to...

Scotch Broom is a serious environmental weed in Barrington Tops National Park and the surrounding areas. It poses a significant threat of reducing the diversity of flora in invaded ecosystems and generating a false understorey. It also harbours feral pigs, which perpetuate the cycle of...

This study presents an optimal control model of the Banana Northern Prawn Fishery, one of the most important fisheries in Australia. The life cycle of this species involves migration between the sea, where the catch takes place, and the estuary, where post-larvae and juveniles develop. The model...

With the impending introduction of an Australian Carbon Pollution Reduction Scheme, farmers and landholders in rural Australia have increased opportunities to participate in the market. This includes the adoption of land-use change to sequester additional carbon in exchange for carbon credits...

The goal of sustainability in the management of natural resources and agricultural systems has received increasing attention during the 1990's. The many dimensions of the problem have been extensively discussed in the literature and a recognition of the interaction between economic, biological...

Weeds have many adverse impacts on agriculture and the environment and therefore are often targets of eradication attempts. Eradication attempts involve large commitments of labour and financial resources over significant periods of time. Using data from 12 Australian weed eradication attempts...
