| Dryland salinity emergence is an important land degradation problem in Australia. Large areas of agricultural land where conventional crops and pastures are produced are at risk. The salinisation problem can be controlled by planting trees in conjunction with crops, but a disadvantage of growing trees as a farm enterprise is the long lag between planting and harvest. When farm forestry enterprises are evaluated with conventional discounting techniques they do not generally rank as an attractive alternative to annual crops on productive land. In this paper, a dynamic model that explicitly accounts for decline or improvement in land quality over a period of 40 years is presented. The model is solved for a hypothetical farm on the Liverpool Plains of NSW. The... |

| 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 opportunity to diversify farmer incomes, increase agricultural productivity and provide environmental solutions. It is therefore proposed that the potential role of farm forestry in the wheat-sheep zone is to provide an environmentally and economically sustainable future for farming systems, through tree planting for multiple benefits. A general model is developed for the purpose of economic analysis of agroforestry systems in the wheat-sheep zone using a bioeconomic... |
