Why Danish pig farms have far more land and pigs than Dutch farms? Implications for feed supply, manure recycling and production costs

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…

Negative global phosphorus budgets challenge sustainable intensification of grasslands

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…

Joint Actions for Air Quality and Climate Mitigation in Europe

Combined action for air and climate can be undertaken by (i) targeting atmospheric compounds that happen to have detrimental impacts on health, ecosystem and climate at the same time (short lived…

Exploring resource efficiency for energy, land and phosphorus use: Implications for resource scarcity and the global environment

In this paper, we present four model-based scenarios exploring the potential for resource efficiency for energy, land and phosphorus use, and implications for resource depletion, climate change and…

Impacts of European livestock production: nitrogen, sulphur, phosphorus and greenhouse gas emissions, land-use, water eutrophication and biodiversity

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…

Global and regional climate impacts of future aerosol mitigation in an RCP6.0-like scenario in EC-Earth

Future changes in aerosol concentrations will influence the climate system over the coming decades. In this study we evaluate the equilibrium climate response to aerosol reductions in different parts…

Exploring, exploiting and evolving diversity of aquatic ecosystem models: a community perspective

Here, we present a community perspective on how to explore, exploit and evolve the diversity in aquatic ecosystem models. These models play an important role in understanding the functioning of…

How well do integrated assessment models represent non-CO2 radiative forcing?

This study aims to create insight in how Integrated Assessment Models (IAMs) perform in describing the climate forcing by non-CO 2 gases and aerosols. The simple climate models (SCMs) included in IAMs…

Phosphorus budget in the water-agro-food system at nested scales in two contrasted regions of the world (ASEAN-8 and EU-27)

In this paper the P cycle in anthropic systems is analyzed with an original multiscale approach (world region, country, and large basin scales) in two contrasting world regions representative of…

Nutrient load estimates for Manila Bay, Philippines using population data

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…
