Highlights by GreenFacts of the report “Our Nutrient World” prepared by the Global Partnership on Nutrient Management in collaboration with the International Nitrogen Initiative
THE REPORT IN A GLANCE followed by its Highlights in 8 Questions and answers
1. The aim of this report This report highlights how nitrogen and phosphorus fertilizers are estimated to feed half the human population alive today, and how they will remain critical in the future, especially given increasing population and potential bioenergy needs. The report shows how these problems cross all global change challenges, threatening water, air and soil quality, climate balance, stratospheric ozone and biodiversity. The report also highlights that there is still no intergovernmental framework to address the multiple challenges for nitrogen, phosphorus and other nutrients.
2. The specific threats related to nutrients Without swift and collective action, the next generation will inherit a world where many millions may suffer from food insecurity caused by too few nutrients, where the nutrient pollution threats from too much will become more extreme, and where unsustainable use of nutrients will contribute even more to biodiversity loss and accelerating climate change.
3. Why are nutrients so important The world needs nutrients, especially nitrogen (N) and phosphorus (P), which are essential to raise crops and animals have more than doubled and their natural cycles are now out of balance, causing major environmental, health and economic problems that have received far too little attention.
4. The most critical environmental risks regarding nutrients The five key environmental threats of too much or too little nutrients are Water quality , air quality , greenhouse gas balance, ecosystems & biodiversity and soil quality.
5.The risks of nutrient shortage On average over 80% of Nitrogen and 25-75% of Phosphorus consumed (where not temporarily stored in agricultural soils) end up lost to the environment, wasting the energy used to prepare them, and causing air and water pollution. In particular finite phosphorus reserves in particular represent a potential risk for future global food security given that there is no alternative to P as an essential plant nutrient.
6. How to adress these nutrient challenges Reduce nutrient losses and improve nutrient use efficiency across all sectors simultaneously would provide the foundation for a Greener Economy to produce more food and energy while reducing environmental pollution. This effort must cross the boundaries between economic sectors and environmental media, be underpinned by scientific and other evidence from a robust global assessment process, share best practices, and address the substantial cultural and economic barriers that currently limit adoption.
7. The actions and outcomes that need to be decided Ten main domains were identified in the report on which action should be concentrated in the area of agriculture, transport and Industry, waste and recycling, societal consumption patterns and spatial and temporal optimization of nutrient flows. One option is to strengthen the mandate of the ‘Global Programme of Action for the Protection of the Marine Environment from Land-based Activities’ (GPA). Continue reading
