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...

Giant clams offer small holders throughout the Indo-Pacific with good prospects for commercial culture to satisfy their increasing dependence on the cash economy. Two species appear promising for an emerging village-based export industry in Solomon Islands. These species are Tridacna crocea, the...

Spiny lobster puerulus settlements have recently been found in bays in Lombok, Indonesia, leading to the development of lobster grow-out culture in adjacent areas. This research suggests that lobster farming in Indonesia is a viable alternative livelihood for Indonesian fishers. Currently,...

Forest management aims at building ecological networks that minimize the impacts on timber production. We formalize the construction of ecological networks in forest environments as the optimal control dynamic graph-theoretic problem. The ecological network is based on a set of bioreserves and...

The performance of over 500 North Dakota farms, 2002-2011, is summarized using 16 financial measures. Farms are categorized by geographic region, farm type, farm size, gross cash sales, farm tenure, net farm income, debt-to-asset, and age of farmer to analyze relationships between financial...

A generally accepted theory of firm behavior is incorporated into an abstract computerized simulation model capable of handling many different environments and organizations. This model provides a means of studying management problems using the simulation approach by providing, in most...

Historically research about diffusion has largely been focused on rates of adoption and explanations for them. This is a matter of secondary importance, arguably, to the question of the likely total level of adoption. In the case of agricultural innovations total adoption can be expected to be...

In 2001 a survey of five organic cereal-livestock farms was undertaken to assess the economics of organic broadacre farming in recent times. In the mid-1980s a similar study carried out in Eastern Australia found that organic farmers were doing as well as their conventionally farming...
