Surface N balances and reactive N loss to the environment from global intensive agricultural production systems for the periode 1970-2030
The results indicate that the overall system N recovery and fertilizer use efficiency slowly increased in the industrialized countries between 1970 and 1995, the values for developing countries have…
The Netherlands is “well known” for its nitrogen problems; it has one of the highest reactive nitrogen (Nr) emission densities in the world. It is a small country at the delta of several large…
In the past 30 years world production of ruminant meat and milk has increased by about 40%, while the global area of grassland has increased by only 4%. This is because most of the increase in…
Exploring changes in world ruminant production systems
In the past 30 years world production of ruminant meat and milk has increased by about 40%, while the global area of grassland has increased by only 4%. This is because most of the increase in…
Quality and the future. Sustainability outlook. Summary
The quest for sustainability is about the quality of life and the possibilities for maintaining this quality in the future. The extent to which this quest is fulfilled will depend both on the public…
A landmark study released today reveals that approximately 60 percent of the ecosystem services that support life on Earth – such as fresh water, capture fisheries, air and water regulation, and the…
Exploring past and future changes in the ecological footprint for world regions. The Ecological Footprint (EF) has received considerable attention as a useful indicator in the context of sustainable…
Outstanding Environmental Issues for Human Development
In this report it is shown that under business-as-usual scenarios, key issues for development such access to clean drinking water, food and modern energy will not be solved in time to realize the MDGs…
The significance of climate change in the Netherlands. An analysis of historical and future trends (1901-2020) in weather conditions, weather extremes and temperature-related impacts
A rigorous statistical analysis reveals changes in Dutch climate that are statistically significant over the last century. Annually averaged temperatures have increased by 1.5 about 0.5 degrees…
Global and regional surface nitrogen balances in intensive agricultural production systems for the periode of 1970-2030
The major conclusion of the paper is that despite the expected improvement of the efficiency in many countries, it is clear that the fast increase of production and intensification between now and…
