UN-REDD National Programme Document: Papua New Guinea
Papua New Guinea, Department of Environment and Conservation

Papua New Guinea has taken a global lead in seeking to combat climate change, particularly by proposing measures to realise the carbon abatement opportunity offered by preserving and sustainably managing tropical forests, i.e. by introducing the concept of REDD+ into international negotiations. Domestically, PNG is also committed to mitigating greenhouse gas emissions. The country‘s Vision 2050 envisages low-carbon economic development, aiming to increase per capita GDP by a factor of three by 2030, while maintaining an aspirational goal of net carbon neutrality by 2050.

Global Mangrove Extent Much Smaller than Previously Estimated - UNEP Global Environmental Alert Services (GEAS) - October 2010
United Nations Environment Programme

As confirmed by the impacts of the December 2004 Asian tsunami and Hurricane Katrina in 2005 intact mangroves help stabilize shorelines and thus protect lives and property from such natural disasters. They also provide other ecosystem services such as breeding and nursing grounds for marine species and sources of food medicine fuel and building materials for local communities. In addition living mangroves store carbon keeping it out of the atmosphere. It is possible that mangroves and the soils they grow in could sequester about 22.8 million metric tonnes of carbon each year. Mangrove forests occur between the sea and land and are thought to cover about a quarter of the world's tropical and subtropical intertidal zones mostly between 5° N and 5° S latitude. Research reveals that the forests have been declining at an alarming rate however' perhaps even faster than inland tropical forests' and much of what is left is degraded.

Building the Foundations for Sustainable Nutrient Management. A publication of the Global Partnership on Nutrient Management
United Nations Environment Programme

This booklet focuses on the use, effects and management of two key nutrients - nitrogen and phosphorous. Together they play an important role in the global and local sustainable development agendas. On the one hand, their production and use means higher levels of crop production and food security. On the other hand, their excess use and production, the result of a range of important human activities, leads to severe pollution of air, water, land and sea around the world. The present result is an apparent divide between societal needs for food and energy and a complex web of adverse environmental impacts, which undermine ecosystems and the services, and livelihoods they provide. This conundrum is set to intensify, to the cost of countries as demand for food and energy increase and the levels of demand for nitrogen and phosphorous grow.
