This document discusses nutrient pollution and the Global Partnership on Nutrient Management. It notes that oceans provide key services for the planet but are suffering from pollution, including nutrient pollution. Nutrient overloading is a major concern as it leads to eutrophication, hypoxia, and harmful algal blooms. The Global Partnership on Nutrient Management was established under the Global Programme of Action to address this issue through knowledge sharing, best practices, and engaging partners to promote sustainable nutrient management.

Since July 2006, UNDP/GEF-SGP has supported 75 projects in Ethiopia, out of which, 13 of them were being implemented in Dire Dawa Administration. Taking the already phased out four community projects as a reference, this study examines the socioeconomic impacts of the program in the Administration. A cross sectional survey of 160 households (80 from the project beneficiaries and 80 from non-beneficiaries) was undertaken to examine and evaluate the impacts of the program on households’ livelihood. Descriptive statistics coupled with an econometric model was used to analyze the data collected from different sources. The descriptive analysis of this study indicates that the societies are becoming better off in their livelihood due to the existence of the project despite the fact that it is associated with many challenges. Applying a propensity score matching technique, the study has figured out that the level of monthly income, asset and monthly consumption expenditure of the program beneficiaries are higher than that of non-beneficiaries. Generally, the major findings of the study showed the average effect of the program to be positive and statistically significant; suggesting that the program has achieved its stated objectives of improving the socio economic conditions of the local community and the environment. It is also suggested that the project would have the capacity to improve the livelihood of the beneficiaries further if corrective measures are taken to tackle the challenges faced by the project.

How to prevent Ocean pollution?
The oceans cover over 70% of the globe. Its health, wellbeing of humanity and the living environment that sustains us all are inextricably linked. Yet neglect of ocean acidification, climate change, polluting activities and over-exploitation of marine resources have made oceans, one of the earth’s most threatened ecosystems.
Marine pollution, also known as ocean pollution, is the spreading of harmful substances such as oil, plastic, industrial and agricultural waste and chemical particles into the ocean.
Environmental Pollution, Global Climate Change and Biodiversity Management approaches
current status of pollution levels (air, soil and water), strategies implied to curb the problem (particularly in India) and recent research carried in different parts of the world. Mitigation and adaption approach to climate change.

2. The global concern of oceans pollution
• Oceans and Coasts – the very basis of much of the world’s
economy.
• 350 million jobs globally linked to the oceans.
• Marine environment supplies planet with key services
• climate regulation, storm protection, food security, nutrients cycling etc..
• All these services underpin lives and livelihoods in different sectors from
tourism to fisheries.
• Oceans are suffering from advanced degradation mainly as a result
of human activities.
• Over the past decades marine pollution has become an increasingly
significant problem.
• particles, industrial, agricultural and residential waste, noise, plastic debris or
the spread invasive organisms. Nutrient pollution is a major concern
• Population pressure set to reach nine billion by 2050
• Pollution impacts likely to be severe unless global action is taken to
sustainably manage and protect oceans and coastal ecosystems

11. Air quality & Greenhouse balance
• Climate drivers also important in
land-atmosphere interactions with
respect to pollution through
emissions of greenhouse gas nitrous
oxide (N2O) and ammonia (NH3) to
the atmosphere
• N2O contributes to stratospheric
ozone depletion, increasing the risk
of skin cancer from UV-B radiation
12. Soil quality and land degradation
• Nutrient deficits in parts of the
globe – African continent of note
• Extraction of nutrients without
replenishment, physical erosion
• Land degradation and declining yields
• Climate change will exacerbate
conditions
• Deeping land degradation with
changes in temperature and
moisture/water regimes
13. Towards global action…
• Established by the Washington Declaration
• Over 108 governments declared commitment
to protect and preserve the marine
environment from impacts of land-based
activities
• GPA adopted in 1995
• Only global intergovernmental mechanism
explicitly addressing the linkages between
freshwater, coastal and marine
environments.
• Voluntary, action-oriented,
intergovernmental programme led by
UNEP
• GPA designed to address accelerating
degradation of the world’s oceans and coastal
areas
14. Global Partnership on Nutrient Management (GPNM)
• Multi-sectoral international partnership
• Established under the GPA in 2009
• Key roles:
• Catalyze strategic advocacy and co-operation at the global and regional
levels
• As a knowledge platform to support science policy interaction and
translating science for policy makers
• To provide information and enhance capacities to address the growing
problem of nutrient over-enrichment and eutrophication
• To position nutrient issues as part of the international sustainable
development agenda
• advance Sustainable Development Goals, in particular under Goal
14 on conservation of the oceans and Goal 2 on sustainable
agriculture
15. Partnership strengthening
Enhancing advocacy and knowledge exchange

Editor's Notes
A safe operating space for humanity: Johan Rockström et al., Nature 461, 472-475 (24 September 2009)
The inner green shading represents the proposed safe operating space for nine planetary systems. The red wedges represent an estimate of the current position for each variable. The boundaries in three systems (rate of biodiversity loss, climate change and human interference with the nitrogen cycle), have already been exceeded.
N cycle (part of a boundary with the P cycle):
Parameter: Amt of N2 removed from the atmosphere for human use – mill/tonnes/yr
Proposed boundary: 35 mill/tonnes/yr
Current status: 121 mill/tonnes/yr
P cycle (part of a boundary with the N cycle):
Parameter: Amt of P flowing into the oceans – mill/tonnes/yr
Proposed boundary: 11 mill/tonnes/yr
Current status: 8.5 - 9.5 mill/tonnes/yr
Major inequalities exist between those parts of the world using excess nutrients and those that do not have enough. The key regions where too much nutrients are typically used include North America, Europe, and parts of South and South East Asia and Latin America. By contrast, many parts of Africa and Latin America have insufficient access to nutrients, leading to soil nutrient mining and limiting productivity.
In agricultural soils N and P applied as fertilisers can be washed off and reach surface waters by runoff or can move into the aquifer through leaching, eventually arriving at surface waters. In developed countries and intensive agricultural regions this diffuse source of nutrients represents
a major cause of water pollution. Regions using excessive nutrient input have higher diffuse water pollution (Billen et al., 2011, Grizzetti et al., 2011). The map shows the estimated net anthropogenic nitrogen input according to the world’s main river catchments (Billen et al., 2013).
Values are based on the dataset of the UNESCO-IOC project Global-Nutrient Export from WaterSheds “Global-NEWS” (http://marine.rutgers.edu/globalnews/index.htm)
The scale of the differences is illustrated for major river catchments, with these being exacerbated by differences in nutrient use efficiency across the full chain.
Map shows calculated spatially explicit P balances for cropland soils at 0.5° resolution based on the principal agronomic P inputs and outputs associated with production of 123 crops globally for the year 2000. Although agronomic inputs of P fertilizer and manure collectively exceeded P removal by harvested crops at the global scale, P deficits covered almost 30% of the global cropland area. There was massive variation in the magnitudes of these P imbalances across most regions, particularly Europe and South America. High P fertilizer application relative to crop P use resulted in a greater proportion of the intense P surpluses globally than manure P application. High P fertilizer application was also typically associated with areas of relatively low P-use efficiency. Although manure was an important driver of P surpluses in some locations with high livestock densities, P deficits were common in areas producing forage crops used as livestock feed. Resolving agronomic P imbalances may be possible with more efficient use of P fertilizers and more effective recycling of manure P. Such reforms are needed to increase global agricultural productivity while maintaining or improving freshwater quality.

When N and P enter the sea they do the exact same thing they did on land, they fertilize the sea, and promote the production of algae and phytoplankton, which is extra organic matter to the ecosystem. The decomposition of this excess organic can drastically alter the way marine ecosystems function and often lead to hypoxia – a shortage of oxygen in the water – suffocating marine life. In addition, this extra N and P changes the natural balance between these nutrients, allowing harmful algal blooms to develop, threatening fisheries and human health.
Sedimentation and decomposition of biomass from phytoplankton blooms can also deplete oxygen in bottom waters and surface sediments, especially in ecosystems with low rates of water turnover (e.g. Rabalais, 2002). This further shifts the benthic community toward a smaller
number of tolerant species. Changes in the benthic community alter nutrient cycling in the sediments and overlying water, feeding back to alter the rest of the aquatic ecosystem (Grizzetti et al., 2011).
The relative importance of N and P varies according to the issue being considered. In groundwater, the key problem is accumulation of nitrate. In freshwater systems, there is often a relative surplus of N compared with P, so the water body is said to be ‘phosphorus-limited’. This means that further P input becomes the most usual driver of algal blooms. By contrast, coastal marine ecosystems are more often considered to be ‘nitrogen-limited’ so that additional Nr is more often the source of problems with algal blooms in these situations.
NOTE: the background map on which the hypoxic systems are superimposed (as red dots) is from ERIC W. SANDERSON et al., 2002. The Human Footprint and the Last of the Wild http://bioscience.oxfordjournals.org/content/52/10/891.full.pdf+html. The ‘human footprint’ legend is a quantitative evaluation of human influence on the land surface, based on a number of geographic data parameters, normalized to a 0 to 100 scale.
Environmental impacts, from air quality to soil quality – coined as ‘WAGES”. The next sides illustrate the impacts in each of these areas
There may be increasing adverse impacts related to nutrient loading as the oceans warm – more harmful algal blooms with fish kills, more eutropication
