Nutrient management valuation in Rondonópolis municipality in the upper Pantanal Region of South America.

This work was developed to target agricultural (crop and livestock) systems and associated wastewater management systems, linked to nutrient management. We evaluate nutrient use practices based on scientific sound methodology, applied on similar studies in many regions of the world. Therefore, the work approach we used can be replicate to other regions. The methodological strategy and results are useful information for the agriculture and environmental sector stakeholders and decision makers in Brazil, and potentially, other countries.

Development of an Ecosystem Heath Report Card for Lake Naivasha, Kenya

The issue of pollution of fresh and coastal waters and the harmful impacts on human health, ecosystem health and economies rank high on national development agendas in the context of the 2030 Agenda for Sustainable Development and its Sustainable Development Goals (SDGs). Countries have been developing and implementing approaches to combat land-based pollution and there are lessons to be shared in the adoption of success stories between countries.

Lake Chilika Ecosystem Health Card 2014

After earlier editions, the 2014 version of the Lake Chilika Ecosystem Health Card is now available.

Coupling global models for hydrology and nutrient loading

The Integrated Model to Assess the Global Environment–Global Nutrient Model (IMAGE–GNM) is a global distributed, spatially explicit model using hydrology as the basis for describing nitrogen (N) and phosphorus (P) delivery to surface water, transport and in-stream retention in rivers, lakes, wetlands and reservoirs.

Global riverine N and P transport to ocean increased

One of the major cause of increased retention is the growing number of reservoirs which now account for 10 24 and 22% of global N and P retention/removal in freshwater systems, respectively.

Position Paper - Nitrogen Use Efficiency and Nutrient Performance Indicators

This paper offers the technical basis and supporting research for using Nitrogen Use Efficiency (NUE) as a performance indicator to improve global food production and control the potential harmful environmental impacts of excess nitrogen-based compounds from manufactured and animal waste fertilizers. NUE implies a more precise application of nutrients that is based on current agronomic principles in combination with other factors like soil health, water availability, climate, and type of crop.
