This paper explores the economics of land degradation in the rice-shrimp system inthe Mekong Delta of Vietnam. A bioeconomic NPV model was developed toevaluate and compare the long-term benefits of alternative production choices andfarm technologies.
Benefits ascribed to the revegetation of farming landscapes include enhancement ofbiodiversity, reduction in the advance of dryland salinity, sequestration of greenhousegases, control of soil erosion, greater protection of agricultural activities from adverseweather conditions and an improved aes
In this paper we present results of a statistical analysis of 380 landholders in the North Central and North East regions in Victoria that were interviewed after the first bidding round of the BushTender scheme.
Growing trees with crops has environmental and economic implications. Trees can help prevent landdegradation and increase biodiversity while at the same time allow for the continued use of the land toproduce agricultural crops.
Over the last decade the Vietnamese government has instigated land reforms thatrecognise the household as the basic unit of production and allocate land use rights tohouseholds. Under the 1993 Land Law these rights can be transferred, exchanged,leased, inherited, and mortgaged.
A farming systems and rotations trial was conducted at Minnipa on the Eyre Peninsulaof South Australia between 1995 and 2001.
An appropriate economic framework for valuing the benefits of weed management technologies is to treatweeds as a renewable resource stock problem. Consequently, the weed seed bank is defined as a renewableresource that changes through time due to management and seasonal conditions.
Several approaches have been proposed for accounting for temporary carbonsequestration in land-use change and forestry projects that are implemented to offsetpermanent emissions of carbon dioxide from the energy sector.
Dryland salinity, as an externality, has an impact on various public assets, including roads,biodiversity and public water supplies. This has been seen as an important justification forgovernment to take action and internalise the pollution.
