Biodiversity - Global Environment Outlook (GEO-6): Healthy Planet, Healthy People Chapter 6
United Nations Environment Programme

Biodiversity is in crisis. There is well-established evidence indicating an irrevocable and continuing decline of genetic and species diversity, and degradation of ecosystems at local and global scales. Scientists are increasingly concerned that, if anthropogenic pressures on Biodiversity continue unabated, we risk precipitating a sixth mass extinction event in Earth history, with profound impacts on human health and equity.

Cross-cutting Issues - Global Environment Outlook (GEO-6): Healthy Planet, Healthy People Chapter 4
United Nations Environment Programme

As understanding of the interdependence between a healthy planet and healthy people becomes more developed, complex issues that thread through systems and societies gain new importance. Beyond the traditional Global Environment Outlook (GEO) themes addressing air, biodiversity, oceans, land and fresh water, this GEO-6 assessment addresses cross-cutting issues worthy of further examination. Using
a systems approach, these cross-cutting issues offerentry points allowing another dimension for analysing GEO-6 themes as well as understanding the network of interconnections throughout earth and human systems.

Measuring Progress: Towards Achieving the Environmental Dimension of the SDGs
United Nations Environment Programme

Did you know that only 23% of the environment-related SDG indicators are on track to meet the target if current trends continue? For 68%, there is not enough data to assess progress and for 9% there is not progress toward achieving the target. Specifically, progress has been made on all 11 environment-related SDGs indicators related to policy, financial and institutional processes with available data; there has been mixed progress in improving access to environmental resources and reducing the impacts of environmental degradation on human health and food security; and there is either no data or no progress towards all 12 of the SDGs targets related to the state of the environment. In order to achieve the environmental dimension of sustainable development, there is a need to scale up environmental action and also to improve environmental monitoring and analysis.

Invest in a Healthy Planet - Invest in UN Environment
United Nations Environment Programme

Since 1972, the UN Environment Programme has served as a powerful advocate for the environment. This publication further illustrates who we are and what we do. It also makes the case for the importance of flexible core financial resources; how they are the bedrock of our work and enable us to invest in essential capacity and expertise to deliver the work that our 193 Member States mandate us to do.

Global Linkages: A Graphic Look at the Changing Arctic
United Nations Environment Programme

The new report “Global Linkages – A graphic look at the changing Arctic”, produced by UN Environment and its collaborating center GRID-Arendal, is a set of maps and graphics, accompanied by short narratives to synthesize and illustrate the most critical, connected environmental challenges with Arctic and global relevance and focusing on issues which call for common solutions. The graphics builds on Arctic and global environmental assessments and reflect the dynamic connection between the Arctic and the rest of the planet. It presents both trends and outlooks and provides actionable recommendations focused on policy development and options for solutions. The issues covered by this product reflect the themes of the current Finnish Chairmanship of the Arctic Council – climate change, biodiversity conservation and pollution prevention.

Maladaptation to Climate Change: Avoiding Pitfalls on the Evolvability Pathway - Frontiers 2018/19: Emerging Issues of Environmental Concern Chapter 5
United Nations Environment Programme

As climate change negotiations progressed, researchers examined how and why some adaptation actions go awry, particularly those actions that waste substantial amounts of human, natural, or financial resources. Maladaptation thinking continues to advance, and one influential study considered the problem according to the outcomes, identifying five categories of maladaptation when compared to
alternative choices. According to this analysis, maladaptations are actions that increase greenhouse gas emissions, burden the most vulnerable disproportionately, incur high opportunity costs, reduce incentives to adapt, or set paths that limit the choices available to future generations.

The Nitrogen Fix: From Nitrogen Cycle Pollution to Nitrogen Circular Economy - Frontiers 2018/19: Emerging Issues of Environmental Concern Chapter 4
United Nations Environment Programme

Nitrogen is an extremely abundant element in the Earth’s atmosphere. In the form of the N2 molecule, nitrogen is harmless, making up 78 per cent of every breath we take. The two nitrogen atoms are held together by a strong triple bond (N N), making it extremely stable and chemically unreactive. The planet benefits because N2 allows a safe atmosphere in which life can flourish, while avoiding the flammable consequences of too much oxygen. The environmental interest in nitrogen focuses on the conversion of N2 into other
chemically reactive forms. For simplicity, scientists refer to all other nitrogen forms as “fixed” or “reactive nitrogen” (Nr).

Permafrost Peatlands: Losing Ground in a Warming World - Frontiers 2018/19: Emerging Issues of Environmental Concern Chapter 3
United Nations Environment Programme

Permafrost thaw is seen as one of the most important “tipping elements” that could precipitate a runaway greenhouse effect, or an uncontrollable “Hothouse Earth”. To avoid such a destructive scenario, it is critical that the world’s permafrost and its peatlands stay frozen and retain their carbon deposits.
