During the 14th meeting of the Conference of the Parties to the Convention on Biological Diversity (CBD) in Sharm El-Sheikh, Egypt, November 2018, Prof. N. Raghuram, Chair of the International Nitrogen Initiative and member of the GPNM Steering Committee, participated in a side event 'Soil in the nexus - Soil and Biodiversity: role and importance in the nexus'. He highlighted the fact that while nutrient pollution is at the heart of the three Rio conventions, very little attention is placed on the issue in the context of meeting obligations under the Convention. He framed the priority of addressing nutrient pollution in the context of findings and recommendations of the European Nitrogen Assessment and the recently published Indian Nitrogen Assessment.

The Toward an International Nitrogen Management System (INMS) funded by the Global Environment Facility will contribute to strengthening the basis for action through both global-level and regional-level assessments, driven by future scenario analyses. He noted that consideration needs to be given to a global policy arena for nitrogen management, interlinked with the multiple intergovernmental processes that currently exist, including the CBD. The discussion considered the unbalanced and geographically uneven access to and use of fertilizers (e.g. in the Africa region), and the need for fine-tuning best practices in nutrient use efficiency in accordance with the agro-ecological conditions. There is recognized need for better synergies between agriculture and environment ministries in designing mutually benefiting policies to effect for better results on the ground from both the perspective of food production and maintenance of ecosystem services.

Transferring Best Practices in Water Pollution Assessments from Laguna Lake, Philippines and Chilika Lake, India, to Lake Naivasha, Kenya

Workshop participants at Lake Naivasha, Kenya

Over the 24 to 28 September, the Secretariat of the Global Partnership on Nutriment Management, in association with the Global Programme of Action (GPA), in co-operation with the Freshwater Ecosystems Unit of UN Environment, organized a technical exchange between experts from Laguna Lake Development Authority (LLDA) of the Philippines, Chilika Lake Development Authority (CDA) of India and national stakeholders concerned with preserving the environmental and water quality of Lake Naivasha in Kenya. This exchange was to facilitate the development of an Ecosystem Health Report Card (EHRC) in a replication effort for Lake Naivasha, based on work undertaken in India and the Philippines as part of the GEF-Global Nutrient Cycle Project, that is executed by the Global Programme of Action with oversight by the Steering Committee of the GPNM. On Monday 24 September, the experts and participants convened at UN Environment for a Symposium that marked the commencement of the activity, where they had a chance to meet various stakeholders, including UN Environment technical personnel, and representatives from Permanent Missions to UN Environment in Nairobi. This was followed by a three-day workshop with local stakeholders at Naivasha in which participants discussed the water pollution challenges and key considerations related to the development of an Ecosystem Health Report Card for Lake Naivasha. Nutrient pollution loading was identified among the critical issues that are plaguing the lake ecosystem. The workshop concluded with the development of roadmap for replication of the ecosystem health scorecard for Lake Naivasha in coming months.

Core funding for the technical exchange was from the UN Environment project ‘Addressing the Nutrient Challenge through an Effective Global Partnership on Nutrient Management (GPNM), the ‘GEF Global Nutrient Cycle Project’; and ‘Strengthening the normative basis for planning, monitoring and managing water quality for aquatic ecosystems’, a project supported under UN Environment's Freshwater Ecosystems Unit. Further assistance was provided under GEF-International Waters Learning Exchange and Resources Network (IW LEARN) in the participation of two participants associated with related GEF and World Bank projects in the Caribbean and Romania.

Key collaborators included the Laguna Lake Development Authority, National Centre for Sustainable Coastal Management, India, Imarisha Naivasha, Lake Naivasha Riparian Association, World Wildlife Fund for Nature, Ministry of Water of Kenya, Water Resources Authority of Kenya and the National Environment Management Authority of Kenya.

The 6th Sustainable Phosphorus Summit, Brasilia

Participants at the SPS2018

Phosphorus is an essential element for both plant and animal growth and is not replaceable by other elements. In the last 50 years phosphate fertilizers have enhanced crop yields, providing food for billions of people and livestock. World food security is dependent on sufficient access to phosphorus fertilizers for farmers. Phosphorus security is critical for realizing many goals of global society. These include food security and provision of clean water, integrity of ecosystems and fertile soils, maintaining livelihoods, human health and geopolitical security. However, there is little global joined-up thinking about how we can deliver a secure phosphorus future.

At the 6th Sustainable Phosphorus Summit (SPS2018) held in Brasilia, Brazil over the 20 to 22 August 2018, diverse science, policy and industry stakeholders gathered together from different parts of the food production and consumption chain, to advance knowledge and identify actions regarding the role of phosphorus availability and accessibility in food security and agriculture, protecting the environment, and supporting rural and urban livelihoods. The summit was organized by Brazilian Agricultural Research Corporation (EMPRAPA).

Participants agreed that there is emerging consensus on a global declaration from the scientific community on more sustainable phosphorus management. This message was carried from the third European Sustainable Phosphorus Conference held in Helsinki, Finland in June 2018 where scientists considered a "Helsinki Declaration", a global call to policy makers worldwide to support progression towards more sustainable phosphorus management. The Global Partnership on Nutrient Management (GPNM) Secretariat contributed to a session on ‘Phosphorus and global environmental governance’ that sought to gain consensus and recommendations on a global policy strategic approach that may be facilitated by UN Environment and feed into implementation of the Third session of the United Nations Environment Assembly (UNEA-3) resolutions on pollution, with specific reference to the resolution on water pollution.

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

The Pantanal ©Mato Grosso

The Global Partnership on Nutrient Management (GPNM) case study on Nutrient Management Valuation in Rondonópolis municipality in the upper Pantanal Region of South America has concluded. The study was led by Felipe Pacheco of the Brazil National Institute for Space Research in association with the Federal University of Mato Grosso.

The study resulted in a valuation methodology to assess nitrogen and phosphorus inputs from fertilizer application and other pathways; the outflows from the system, and estimated costs and benefits in terms of agricultural production, human health, ecosystem and climate impacts. The Vermelho River watershed, a 23,265 km2 basin was used to develop the methodology.

The study concluded that the total costs tend to exceed the benefit of nitrogen fertilization by US$2.3 million dollars per year. This value is relatively low compared to the total of the benefits estimated at US$37 million and costs estimated at US$39 million, where the benefits of nitrogen use is offset by the impact of nitrogen emissions. The obvious options for better practice are reducing emissions NH3 and N2O, as these reactive nitrogen emissions generate most social and environmental costs. The common use of urea as fertilizer in the region may represent the main source of ammonium volatilization. Changes in the type of fertilizer use (e.g, ammonium sulphate) may be an option to reduce reactive nitrogen emissions.

Estimated nitrogen and phosphorus budgets in crop systems in the Vermelho River Basin

The methodology and approach applied can be used as a tool for local and regional agricultural production planning in Brazil and applied potentially to other countries through the Global Partnership on Nutrient Management (GPNM). This work, is the first of its kind in a developing country; and there are possibilities will be scaled-up under the GEF-Toward and Integrated Nitrogen Management System (INMS) Project being implemented by the UN Environment.

Where Animal Poop Is Turning into Deadly Ammonia Pollution

Source: Brandon Specktor, Live Science, December 5, 2018

Researchers at Université Libre de Bruxelles (ULB) in Belgium have used nine years of satellite data between 2007 and 2016, gathered by the MetOp satellite mission, to create the most comprehensive map of global atmospheric ammonia ever made. The data comes from a series of three meteorological satellites launched by the European Space Agency to catalog the various components of our planet's atmosphere, including ammonia. The study revealed 242 ammonia "hotspots" (emission zones with a diameter of less than 31 miles, or 50 kilometers), as well as 178 wider emission zones, confirming that 241 of them were clearly linked to human activities. Of those, 83 were linked to intensive livestock farming and 158 were linked to other industries, mainly plants producing ammonia-based fertilizer.

Atmospheric ammonia fluxes based on 9 years of satellite data shows 242 ammonia hot spots (surrounded by black circles) and 178 wider emission zones (framed by white rectangles). According to a new study, about two thirds of these hot spots were previously unknown. Credit: Martin Van Damme and Lieven Clarisse/ULB

Emissions of forms of reactive nitrogen such as ammonia are intense from large industrial farms where large volumes of animal manure decomposes - the released ammonia can combine with other compounds to pollute the air, water and soil. Exposure to these polluted resources can lead to lung disease and death in humans as well as crop failure and mass animal death. The findings suggest that we have been vastly underestimating the amount of ammonia our industries are releasing into the atmosphere. According to the researchers, two-thirds of the hotspots they found have not been previously reported in prior environmental surveys, while emissions from other hotspots have been significantly under-reported.

The Ocean is losing its breath: declining oxygen in the world's ocean and coastal waters

Pasig River where it meets Manila Bay, the Philippines

Since the 1960s, the area of low oxygen water in the open ocean has increased by 4.5 million km2 and over 500 low oxygen sites have been identified in estuaries and other coastal water bodies. Human activities are a major cause of oxygen decline in both the open ocean and coastal waters; this is from burning of fossil fuels which result in climate change, coupled with discharges from agriculture and human waste, notably in the form of nitrogen and phosphorus inputs. Intensive aquaculture operations can contribute to deoxygenation by due to oxygen demand for respiration by both the farmed animals and by microbes that decompose their excess food and faeces.

The process of warming of oceans driven by climate change reduces the supply of oxygen to the open ocean and coastal waters by increasing stratification and decreasing the solubility of oxygen in water. Deoxygenation may also contribute to climate change through its effects on the nitrogen cycle. When oxygen is insufficient for aerobic respiration, microbes conduct denitrification to obtain energy. This produces N2O – a powerful greenhouse gas – as well as N2, which is inert and makes up most of the earth’s atmosphere.

Impacts of excess nutrients (eutrophication) on ocean oxygen. (Figure modified from https://upload.wikimedia.org/ wikipedia/commons/d/dd/Scheme_eutrophication-en.svg)

The impacts on marine biodiversity and productive fisheries is far-reaching as insufficient oxygen reduces growth, increases disease, alters behaviour and increases mortality of marine animals, including finfish and shellfish. Finfish and crustacean aquaculture can be particularly susceptible to deoxygenation because animals are constrained in nets or other structures and cannot escape to highly-oxygenated water masses.

The problem of deoxygenation is predicted to worsen in the coming years. Global warming is expected to worsen deoxygenation during the twenty-first century due to continued greenhouse gas emissions. The global discharge of nitrogen and phosphorus to coastal waters may increase in many regions of the world as human populations and economies grow. It is expected that many areas will experience more severe and prolonged hypoxia than at present under the same nutrient loads. Urgent steps required to limit this global trend; addressing land-based pollution through improved fertilizer use efficiency, better management of manures from livestock production and improved sewage treatment are among the frontline measures.

The Nitrogen Problem: Why Global Warming Is Making It Worse

Increases in rainfall and extreme weather triggered by climate change influences will increase the amount of nitrogen runoff from cultivated watershed areas that will pollute rivers and other waterways. Warming water-body and ocean temperatures in response to changing climate will exacerbate the situation. Lakes and other freshwater bodies now routinely face toxic blue-green algae blooms that are fueled by nitrogen pollution that has been presenting serious public health challenges particularly with respect to contamination of drinking water by nitrates; notable cases have occurred in Toledo, Ohio in the United States (2014), Lake Taihu in China (2007), among other occurrences in Brazil and the Philippines. Persistent eutrophication in the Gulf of Mexico, and recent harmful algal blooms along the Florida and Washington State Pacific coasts have had significant economic impacts to fisheries.

The urgency of reforming agriculture to dramatically reduce pollution is gaining more attention. Among the suite of control measures that call for improved fertilizer use efficiency and good agronomic practice, solutions being proposed include cultivation of varieties of genetically-modified cereals that efficiently fix nitrogen from the atmosphere and investment in lab-cultured meat to assist in easing the contributions of the livestock sector to nitrogen emissions.
