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...

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...
