The world agreed to achieve 17 Sustainable Development Goals by 2030. Nine planetary boundaries set an upper limit to Earth system impacts of human activity in the long run. Conventional efforts to achieve the 14 socio-economic goals will raise pressure on planetary boundaries, moving the world away... from the three environmental SDGs. We have created a simple model, Earth3, to measure how much environmental damage follows from achievement of the 14 socio-economic goals, and we propose an index to track effects on people’s wellbeing. Extraordinary efforts will be needed to achieve all SDGs within planetary boundaries.

An IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems
As more frequent droughts and floods threaten the global food supply, humans are increasing their demands on water and land,... The New York Times reports.
Data from the Intergovernmental Panel on Climate Change report:
• 500 million people are living in areas that are becoming desert.
• Soil is depleted at 10X-100X the rate it’s being formed.
• More than 10% of the global population is undernourished.
Major threats include the risk of “multi-breadbasket failure”—simultaneous food crises on several continents—and migration triggered by food shortages.
Good News/Bad News: Catastrophe can be avoided, but it would require massive changes to agriculture, food systems and behavior.
A Key Action: Eat less meat. Cattle production is driving deforestation, consuming huge amounts of water, generating methane and causing other impacts, notes Nature.

Water is the lifeblood of planetary health and human civilisation. As a critical source of fresh water, rivers underpin civilisations, past and present. However, rivers constantly change in response to environmental and human pressures. Protecting global river systems from climate change and other a...nthropogenic activities (e.g., mining, pollution, dam construction), and understanding the interactions with human health (e.g., through the spread of water-borne and infectious diseases) has become a critical concern.

The biosphere underlies the whole sustainable development concept, as the layer on
which society and the economy rely. Nature and biodiversity fuel the natural cycles
and life-support systems of the planet, on which humanity ultimately depends.
Climate change presents significant challenges to human health and biodiversity. Increased numbers of extreme climate events, such as heat waves, droughts or flooding, threaten human health and well-being, both directly and indirectly, through impaired ecosystem functioning and reduced ecosystem ser...vices. In addition, the prevalence of non-communicable diseases is rising, causing ill health and accelerating costs to the health sector. Nature-based solutions, such as the provision and management of biodiversity, can facilitate human health and well-being, and mitigate the negative effects of climate change.

This chapter addresses the biogeochemical cycles of carbon dioxide. (CO2), methane (CH4) and nitrous oxide (N2O)
The Scientific Conceptual Framework for Land Degradation Neutrality (LDN) provides a scientific foundation for understanding, implementing and monitoring LDN. It has been designed to create a bridge between the vision and the practical implementation of LDN, by defining LDN in operational terms. The... conceptual framework is a product of the UNCCD Science-Policy Interface.

Healthy communities rely on well-functioning ecosystems. They provide clean air, fresh water, medicines and food security. They also limit disease and stabilize the climate. But biodiversity loss is happening at unprecedented rates, impacting human health worldwide, according to a new state of knowl...edge review of the Convention on Biological Diversity (CBD) and WHO.
The report synthesizes the available information on the most important inter-linkages between biodiversity, ecosystem stability, and epidemic infectious diseases such as the Ebola virus; and the connection between biodiversity, nutritional diversity and health. It also covers the potential benefits of closer partnerships between conservation and health, from improved surveillance of infectious diseases in wildlife and human populations, to promoting access to green spaces to promote physical activity and mental health. It also highlights the many areas in which further research is needed.
The Joint report hopes to provide a useful reference for the Sustainable Development Goals and post-2015 development agenda, which represents an unique opportunity to promote integrated approaches to biodiversity and health by highlighting that biodiversity contributes to human well-being, and highlighting that biodiversity needs protection for development to be sustainable.

011 - Biogeochemical Cycles
In this video Paul Andersen explains how biogeochemical cycles move required nutrients through the abiotic and biotic spheres on our planet. Matter on the Earth is conserved so producers must receive required nutrients through the water cycle, carbon cycle, nitrogen c...ycle, phosphorus cycle, and sulfur cycle.
