Agricultural research and development (R&D) has being conducted in the upland districts of Cambodia to develop new farming systems and crop management technologies. Levels of farm income in these areas are relatively low due to small farm sizes and low crop productivity. Work is also planned to...

The Commonwealth of Australia Water Act 2007 changed the priority for water use in the Murray-Darling Basin (MDB) to first ensure environmentally sustainable levels of extraction and then to maximise net economic returns to the community from water use. The Murray- Darling Basin Authority (MDBA)...

In this study, the possible impacts of different prices of carbon on farm profitability in two dairy farm businesses with different feeding systems operated over five years were analysed. The feeding systems were a ryegrass pasture-based system (RM) and a complementary forage-based system (CF)....

The Liverpool Plains catchment faces a number of natural resource issues including dryland salinity, which has been attributed to removal of native vegetation, an increase in rainfall and the use of long fallow cropping systems. Opportunity cropping, where a crop is sown once the soil profile...

Natural resource management decision making by Catchment Management Authorities in NSW is being aided by a project involving bio-physical modelling and the development of an alternative decision-making framework. The objective of the bio-physical modelling process is to generate predictions of...

Meshed with the bio-physical and economic dimensions of rural land-use is a social dimension. Understanding the social and economic dimension of rural communities is critical if agencies are to develop effective policies and programs to improve natural resource outcomes. In this paper, we draw...

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...

Management of deciduous perennial fruit crops requires a good understanding of the many physiological and horticultural factors that influence tree growth and fruit production. Crucial decisions that must be made include the choice of tree density, tree variety, pruning and training techniques....

Agroforestry can help in the battle to control global warming by sequestering atmospheric CO2. Most attention so far has been on the carbon sequestered in trees, but soils can also contain considerable amounts of carbon, some of which is released upon harvest. There has been little...

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...
