Dryland Area

 

In the dryland component of the study six different policy options were constructed to represent a broad range of possible approaches to achieving regional targets. The policy options tested ranged from approaches where actions aimed to restore and maintain the condition of natural resources could be implemented anywhere in the landscape without restriction (ie random), to highly strategic approaches which aimed to optimise multiple NRM benefit from actions while minimising costs.

Landscape futures were also analysed under five different scenarios for climate change (temperature and rainfall) and commodity prices for carbon credits (credits may be acquired through carbon sequestration under ecological restoration), biomass, and biofuels. These scenarios have a nominal time horizon of 2070 and included a baseline scenario based on current climate and commodity prices.

Policy Options

Short Description

Go Anywhere

Achieve regional targets by a non-strategic, non-targeted approach of locating NRM actions at random in the landscape

Cheapest

Minimise economic cost of achieving targets

Best for Biodiversity

Achieve biodiversity targets whilst maximising biodiversity benefits, achieve other targets using the Go Anywhere approach

Best for NRM

Achieve regional targets whilst maximising benefits for the multiple environmental objectives of biodiversity, deep drainage, wind erosion, and climate change

Most Cost Effective

Achieve regional targets whilst minimising economic cost relative to benefits for the multiple environmental objectives of biodiversity, deep drainage, wind erosion, and climate change

Sustainability Ideal

Achieve a new set of regional targets aimed at achieving sustainability whilst minimising economic cost relative to benefits for the multiple environmental objectives of biodiversity, deep drainage, wind erosion, and climate change
