Learn more about the Nutrient Challenge
This is a collection of project initiatives the GPNM, its partners and the wider global community has been engaged with and/or under active implementation. This is not intended to be an exhaustive showcase of projects from across the globe but rather an attempt to highlight those initiatives of significant scale of influence and impact in addressing the nutrient challenge. More detailed information will be provided on GPNM projects on this site; readers may however referred to project website for external projects.
As the world continues to grapple with the issue of nutrient pollution, it becomes increasingly important that we work together towards a pollution-free planet. To this end, we welcome you to join us in our efforts to achieve sustainable nutrient management by becoming a member of the Global Partnership on Nutrient Management (GPNM). The GPNM is a multi-stakeholder partnership, therefore membership is open to governments, non-government organizations, intergovernmental organizations, the private sector, academia, civil society organizations and international conventions.

Coastal areas are areas of high productivity where inputs from land, sea, air and people converge. With over 40 per cent of the human population residing in coastal areas, ecosystem degradation in these areas can have disproportionate effects on society (IGOS, 2006). One of the largest pressures on coastal environments is eutrophication, resulting primarily from land-based nutrient input from agricultural runoff and domestic wastewater discharge. Coastal eutrophication can lead to serious damage to marine ecosystems, vital sea habitats, and can cause the spread of harmful algal blooms.
