A methodology to estimate the future extent of dryland salinity in the southwest of western Australia
Received for publication January 27, 2009. In the southwestern agricultural region of Western Australia, the clearing of the original perennial vegetation for annual vegetation-based dryland agriculture has lead to rising saline groundwater levels. This has had effects such as reduced productivity of agricultural land, death of native vegetation, reduced stream water quality and infrastructure ...

Is organic farming climate friendly?
Think organic farming is climate friendly? You might want to think again. A study published recently in the journal Agriculture and Human Values suggests that as organic agriculture emulates conventional industrial agriculture, the environmental benefits may not be the slam-dunk that Earth-loving proponents might like them to be. It’s well known that organic practices offer climate ...

Assessing agroforestry`s advantages
Agroforestry, the deliberate placement of trees into crop and livestock operations, can help capture substantial amounts of carbon on agricultural lands while providing production and conservation benefits. However, we currently lack tools for accurately estimating current and projected carbon values in these systems. In North America, windbreaks are an effective carbon-capturing option. Only ...

Accounting for the market and non-market values of multifunctional outputs in evaluating water transfers to non-agricultural uses: empirical evidence from Taiwanese rice production
Increased demand for water for municipal and industrial uses throughout Taiwan has intensified the pressure to re-allocate water from agricultural to non-agricultural uses. The full policy implications of such water transfers must not only account for the value of lost agricultural production and income, but also any loss in the social value of multifunctional benefits from agricultural ...

Export and import of virtual water from different states of India through food grain trade
The geographical area of India is 3.29 × 106 km2 and the annual average precipitation is about 4000 km3 (about 1215 mm depth over the country). Large variations in agricultural practices, climate and land productivity result in large variations in agricultural productivity between states. Virtual water refers to the water required in the production of goods or services; exchange of water through ...

Land and natural resources lie at the heart of social, political, and economic life in much of rural Africa. They represent fundamental assets—primary sources of livelihood, nutrition, income, wealth, and employment for African communities—and are a basis for security, status, social identity, and political relations. For many rural people, land and resources such as water, trees, and ...

To feed the world in 2050 we have to change course
In order to feed a growing population we need to focus on reducing biofuel production and food waste and spoilage, while supporting small-scale farmers. The 2008 global food price spikes were a wake-up call to global policy-makers, shaking them from the lethargic slumber of the overfed. The rhetorical responses were swift, but policies and practices have changed little. That is in part because ...
