This paper describes a complex, dynamic simulation model that has been developed for the analysis of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli) in rice farming systems in the Philippines. Users of the model may simulate any feasible...

The development of a market in groundwater usage rights can be inhibited by constraints arising from the institutional context. Such impediments may reduce the potential gains from trade and may generate high transaction costs for prospective traders. We analyse the regulations and policies...

In many environmental and conservation policy contexts, gaps are observed between policy objectives and implementation outcomes. Carbon farming policies are designed to mitigate greenhouse gas emissions, but policy success depends on the participation of land managers and their adoption of...

The success of any groundwater management plan depends on user compliance. There is an intimate relationship between regulatory regimes and pumper perceptions. As well as its enforcement powers, an agency's behavior sends information to users. While enforcement power need not always be used to...

Previously titled: The scope for institutional autonomy in a large groundwater basin: the potential for collective action in Western Australia

Groundwater extraction can have varied and diffuse effects. Negative external effects may include costs imposed on other groundwater users and on surrounding ecosystems. Environmental damages are commonly not reflected in market transactions. Groundwater transfers have the potential to cause...

Perth, Western Australia (pop. 1.6m) derives 60% of its public water supply from the Gnangara groundwater system (GGS). Horticulture, domestic self-supply, and municipal parks are other major consumers of GGS groundwater. The system supports important wetlands and groundwater-dependent...

As the largest developing economy, China plays a key role in global climate change. Environmentally extended input-output analysis (EE-IOA) is an important and insightful tool seeing widespread use in studying large-scale environmental impacts in China: calculating and analyzing greenhouse gas...

Several airlines in Australia have initiated voluntary carbon offset (VCO) programs, called 'Fly Carbon Neutral', to encourage their customers to offset the carbon emissions of their flight. A VCO scheme aims to 'neutralise' emissions from a particular activity, by compensating with carbon...
