Agricultural land use and economic growth: environmental implications of the Kuznets curve
The expansion of agricultural land use has been associated with the loss of environmental amenities, such as biological diversity, ecosystem services, and aesthetic values. Here, the determinants of agricultural land use are examined, drawing on panel data from 121 countries over the period 1965–1987. The analysis finds that an inverted U curve (or "environmental Kuznets curve") describes the ...

Evaluating cumulative effects of anthropogenic inputs in Prince Edward Island estuaries using the mummichog (Fundulus heteroclitus)
Estuarine eutrophication as a result of agricultural land use including the use of chemical fertilizers is increasing worldwide. Prince Edward Island, Canada has very high agricultural intensity by international standards with approximately 44% of the land area under production, and some watersheds in excess of 75% agricultural land‐use. The type of agriculture is also intensive with primarily ...

Estimating Phosphorus loss in runoff from manure and fertilizer for a Phosphorus loss quantification tool
Nonpoint-source pollution of fresh waters by P is a concern because it contributes to accelerated eutrophication. Given the state of the science concerning agricultural P transport, a simple tool to quantify annual, field-scale P loss is a realistic goal. We developed new methods to predict annual dissolved P loss in runoff from surface-applied manures and fertilizers and validated the methods ...

The European Grassland Butterfly Indicator: 1990–2011
This report presents the European Grassland Butterfly Indicator, based on national Butterfly Monitoring Schemes (BMS) in 19 countries across Europe, most of them in the European Union. The indicator shows that since 1990 till 2011 butterfly populations have declined by almost 50 %, indicating a dramatic loss of grassland biodiversity. This also means the situation has not improved since the ...

Shedding Light on Land Tenure in Africa
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 ...

Soy Cultivation in South America
The expansion of soy bean Soy cultivation has shown an increasing expansion throughout Argentina, Brazil, Bolivia and Paraguay, in the last decade. This remarkable increase is explained by its economical importance in the region, and as a consequence, it is difficult to regulate its progress and attenuate its potential socio-environmental impacts. In 2012, in these 4 countries the area ...

Using land-time-budgets to analyse farming systems and poverty alleviation policies in the Lao PDR
This paper applies the method of 'Land-time-budget analysis' to a rural subsistence community and to the national economy of the Lao PDR. The analysis is conducted to meet two ends: to identify the community's/the nation's resource use profile in terms of land and time use - the analysis identifies biophysical constraints of socio-economic development and trade-offs in resource use patterns; to ...

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 ...
