This study analyses the financial risk faced by representative mixed-enterprise farmbusinesses in four regions of south-eastern Australia. It uses discrete stochastic programmingto optimise the ten-year cash flow margins produced by these farms operating three differentfarming systems. Monte...

New tree plantations in upland watersheds may directly displace other land uses such as perennial or annual pastures or cropping on arable land, affecting both water yields (W) and river salt loads (S). Our “factorial vector analysis” describes the envelope of possible changes in long run...

This study examines the use of water by existing downstream entitlement holders and their possible market interactions with upstream interests in new forestry plantations in the case of the Macquarie River Catchment, NSW. Demand for offset water to allow upstream plantation establishment is...

It has been widely suggested that changing land use from annual to perennial crops reduces land and stream degradation due to salinization. However, annual crops are financially attractive and increases in perennials can reduce stream flows with adverse effects on stream values. As such,...

This study analyses the financial risk faced by representative mixed-enterprise farm businesses in four regions of south-eastern Australia. It uses discrete stochastic programming to optimise the ten-year cash flow margins produced by these farms, operating three alternative farming systems....

This analysis is based on an experiment aimed at comparing a dryland medic – wheat system with traditional two-year crop rotations with wheat: fallow, watermelon, lentil and vetch. Pasture is marketed through the farmer’s sheep; likewise crop residues (straws and stubbles), but these have...

Farmers commonly apply fixed ‘blind' quantities of nitrogen fertilizer during the fallow or at seeding in rain fed winter wheat-fallow systems in Northcentral Oregon, an area characterized by high year-to-year variation in growing conditions. Knowing crop response to available N depends on...

This document describes a whole-farm model based on data from farm scale crop, sheep and native pasture experiments managed by scientists. The data are integrated using linear programming (LP), and tests of the economic viability of intensified production systems are presented. A six year...

The West Asia/North Africa (WANA) region contains large areas with rainy winters and hot, dry summers. The social-ecology of the region must be respected as well as the physical ecology. Dryland farming, irrigated farming and rangelands in WANA are often linked through the diets of grazing...
