Global foundations for reducing nutrient enrichment and oxygen depletion from land based pollution, in support of Global Nutrient Cycle

Anjan Datta


Recovering Systems oxygen depletion from land based pollution, in support of Global Nutrient Cycle





From: Dumont, et al. 2005 GBC

Increased N inputs are projected in response to increased global population

Grand Challenge of the 21st century:

How to feed 9 billion without N pollution?

UNEP. 2009

UNEP, 2009

The five key threats of excess nutrients global population

The WAGES of

too much or too little of nutrients

Water quality

Air quality

Greenhouse balance


Soil quality

Modified from the European Nitrogen Assessment (2011)

The Project is designed to global population

Address the key Nutrient Challenges

  • Food security

  • Environmental sustainability

Project Objective global population

To provide the foundations (including partnerships, information, tools and policy mechanisms) for governments and other stakeholders to initiate comprehensive, effective and sustained programs addressing nutrient over-enrichment and oxygen depletion from land based pollution of coastal waters

  • Project Outcomes and Outputs global population

  • Development and application of quantitative modeling approaches to estimate and map sources and contributions of different nutrient sources to coastal nutrient loading and their effects; to indicate when nutrient over-enrichment problem areas are likely to occur; and to estimate the magnitude of expected effects of further nutrient loading on coastal systems under a range of scenarios.

  • Development of a “Policy Toolbox”, through which the decision-makers will have informed and interactive access, to cost effective, replicable tools and approaches to develop and implement nutrient reduction strategies

c. global populationExecution of pilot projects in the Manila Bay watershed, Philippines and the Chilka Lake in India for the development and implementation of stakeholders owned, cost-effective and policy relevant nutrient reduction strategies, which can be subsequently mainstreamed into broader planning

d. A strong and vibrant global partnership on nutrient management to provide a necessary stimulus and framework for the effective development, replication, up-scaling and sharing of these key outcomes.

PSC - Rep from governments, industry, science community and UN agencies

PCU – with the all component leaders

MEU - UNEP and GEF rules and procedures

Project Duration: April 2012 – March 2016 (4 Years)

  • GPNM: a multi stakeholders global partnership global population

    • Governments

    • Industry

    • Science community

    • NGOs

    • International organisations

    • Regional Projects

  • GPNM - an One UN initiative

  • Guided by a Steering Committee

  • UNEP is the Secretariat

Role of GPNM global population

Strategic advocacy and co-operation at the global and regional levels to build consensus in promoting NUE

Enhancing the capacities of various stakeholders to design and implement effective management policies

Work with stakeholders to develop guidance, strategies or policies on sustainable use of nutrients

A knowledge platform to support science policy interaction and translating science for policy making

Positioning of nutrient issues as part of international sustainable development agenda

Innovation and knowledge generation to reduce nutrient losses and improve overall NUE

GPNM Activities - to date and translating science for policy making

GPNM and CSD process

Participation in various global, regional and national meetings to raise awareness and mobilize actions

Facilitation of GPNM regional platforms

Knowledge generation e.g., Foundation document, Our Nutrient World, Fact sheet

On the ground intervention – GEF supported GNC project

Outreach, advocacy, consensus building and agenda setting

Task Group: Policy development, policy advocacy and support policy reform/ development (Task Group Leader Prof. Mark Sutton)

  • Nutrient management SDG

  • Defining leverage points and entry strategy

  • Identification of barriers to change

    Development of toolbox to support policy choices and investment decisions (Task Group Leader Prof. Tom Sims)

  • Development of policy toolbox and extension methodology including application of mobile tools

    Defining nutrient performance indicator and nutrient use efficiency (Task Group Leader Dr. Amit Roy)

  • Defining base line of nutrient use efficiency at global as well as regional level as appropriate

  • Defining nutrient performance indicators

  • Establish NUE target for major crops

    Strengthening of partnership (Task Group Leader Dr. Greg Crosby)

  • Secure engagement of: Business councils; Consumer groups; Retail marketing chains; International meat and poultry producers; NGOs and CSOs e.g., WWF, TNC, Oxfam etc. and Professional bodies working in the field of Food Security, Biodiversity and Climate Change

Global “Tool Box” Deliverables policy reform/ development (Task Group Leader Prof. Mark Sutton)

  • A BMP inventory

  • A synthesis of report of policies & practices

  • Toolkits designed for key audiences

  • Five in depth case studies

  • A strategy document/template for replication and up-scaling

  • An operational policy toolbox – integrated w/Component B

  • Training of at least 30 regional and national scientists and policy experts

Outputs policy reform/ development (Task Group Leader Prof. Mark Sutton)

  • 334 best practices have been logged to date from 60 countries

  • Nineteen case studies, additional learning modules developed

  • Initial training module developed

  • Initial synthesis

  • Engage & grow collaborations

  • ASA article published

  • Co-finance secured

Best Practices by Category policy reform/ development (Task Group Leader Prof. Mark Sutton)

Best Practices Tools policy reform/ development (Task Group Leader Prof. Mark Sutton)

Scalability Survey

  • Scalability and Transferability Rating Model

    • Two simple surveys created to give best practices a score ranging from 0 to 10 representing the practice’s ability to be scaled up or replicated in another context.

  • Comparative Efficiency Analysis

    • Based on work in efficiencies modeling by UMD and EPA.

    • Next steps identified in the process of modeling the comparative efficiencies of nutrient management best practices.

Transferability Survey

Key next steps
Key Next Steps policy reform/ development (Task Group Leader Prof. Mark Sutton)

  • Finalizing synthesis

  • Evaluating BMP efficiencies

  • Continue to engage countries to collect policies

  • Developing additional cases

  • Designing integration approach and interface

  • Develop toolkits for use of the inventory

  • Hold training in the field

Indicators used in the report card
Indicators policy reform/ development (Task Group Leader Prof. Mark Sutton)used in the Report Card

  • Chilika Lake Ecosystem Health will be defined as the progress of three water quality indicators (chlorophyll a, dissolved oxygen, and water clarity) and

  • three biotic indicators (aquatic grasses, phytoplankton community, and benthic community) toward scientifically derived ecological thresholds or goals.

  • The six indicators are combined into one overarching Bay Health Index, which is presented as the report card overall score.

Indicators and Indices

Purpose of ecocheck
Purpose of policy reform/ development (Task Group Leader Prof. Mark Sutton)EcoCheck

  • The areas that EcoCheck focuses on are:

    • Increased understanding of how climatology affects fish recruitment

    • Incorporation of spatially explicit data into current management tools.

    • Effective use of ecosystem health indicators.

    • Prediction of fisheries variability with forecast models.

Data requirement for the planned outputs
Data Requirement for the Planned Outputs policy reform/ development (Task Group Leader Prof. Mark Sutton)

  • Water Quality Index:

    • Secchi Disc data (not available until now)

    • Dissolved Oxygen (available – must be made available continuously)

    • Chlorophyll a (data available but usually less frequently analyzed)

  • Biotic Index:

    • a) Phytoplankton (species level data)

    • b) Zooplankton (numbers were given as averages but numbers per m3 or some relevant unit is requested)

    • c) Benthic data to include meiobenthos and macrobenthos

Through this partnership project we would like to ensure policy reform/ development (Task Group Leader Prof. Mark Sutton)
