This document constitutes the GlobalHAB Science and Implementation Plan, which represents an addendum to the GEOHAB Science Plan. It will be used as the basis for carrying out the proposed science over the next decade in coordination with other local, national, and international efforts focused on food and water security, human and ecosystem health, ocean observing systems, and climate change.

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.

 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.

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.
