Phosphorus (P) plays a vital role in global crop production and food security. In this study, we investigate the changes in soil P pool inventories calibrated from historical countrywide crop P uptake, using a 0.5-by-0.5 degree spatially explicit model for the period 1900–2010.
The BioScore 2.0 model analyses impacts of human-induced pressures on European terrestrial biodiversity. The model can be used for scenario analysis and the assessment of policy options. This report provides a detailed description of the methodology and examples of the...
An average Danish pig farm has 3500 pigs, 170 ha of agricultural land, whereas a typical Dutch pig farm has 2500 pigs with only 10 ha. The main factors for the contrasting development are a stronger competition for land, resulting in higher land prices, and stimulation of...
Except for grassland soils in some northwestern European countries, grassland soils in most of the world have been exhausted over recent decades, particularly by exporting more phosphorus that is returned by inputs manure and fertilizer.
Livestock production systems currently occupy around 28% of the land surface of the European Union (equivalent to 65% of the agricultural land). In conjunction with other human activities, livestock production systems affect water, air and soil quality, global climate and...
A major source of nutrient load to periodically hypoxic Manila Bay is the urban nutrient waste water flow from humans and industries to surface water. In Manila alone, the population density is as high as 19,137 people/km2.
Exposure to surface ozone has detrimental impacts on vegetation and crop yields. In this study, we estimate ozone impacts on crop production and subsequent impacts on land use in the 2005–2050 period using results of the TM5 atmospheric chemistry and IMAGE integrated...
Historical trends and levels of nitrogen (N) budgets and emissions to air and water in the European Union and the United States are markedly different. Agro-environmental policy approaches also differ, with emphasis on voluntary or incentive-based schemes in the United States...
Growing global demand for food leads to increased pressure on phosphorus (P), a finite and dwindling resource. China is the largest producer and consumer of P fertilizer in the world. A mass balance analysis of historical P use on China's arable land shows that P input...
Global food production strongly depends on availability of nutrients. Assessment of future global phosphorus (P) fertilizer demand in interaction with nitrogen (N) and potassium (K) fertilizers under different levels of food demand requires a model-based approach. In this...
