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.

The 2012 NDRMP lays out the Disaster Risk Management (DRM) architecture of the country and provides guidance for DRM intervention at all levels. However, implementation has been slow and resource challenges exist throughout the government.
The PNG government’s policy and institutional framework... for DRM still faces numerous obstacles. The main challenges in moving towards a more proactive and systematic approach to manage risks and build resilience include 1.) the limited coordination between DRM and Climate Change Adaptation agencies; 2.) the slow migration from emphasis on response to risk reduction and management; 3.) the limited institutional capacity for planning and design of risk informed investments; and 4.) the lack of available historic natural hazard data, which hinders the assessment of risks.

Much remains unknown about displaced communities in out-of-camp areas as identification constraints hinder knowledge on the overall situation and preeminent needs of an area. When compared to regularly monitored in-camp populations, less is known about the health, sanitation, livelihoods, food secur...ity, nutritional status, protection situation, and school attainment of out-of-camp populations.

Plastic pollution is ubiquitous throughout the marine environment, yet estimates of the global abundance and weight of floating plastics have lacked data, particularly from the Southern Hemisphere and remote regions. Here we re...port an estimate of the total number of plastic particles and their weight floating in the world's oceans from 24 expeditions (2007–2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N = 680) and visual survey transects of large plastic debris (N = 891). Using an oceanographic model of floating debris dispersal calibrated by our data, and correcting for wind-driven vertical mixing, we estimate a minimum of 5.25 trillion particles weighing 268,940 tons. When comparing between four size classes, two microplastic <4.75 mm and meso- and macroplastic >4.75 mm, a tremendous loss of microplastics is observed from the sea surface compared to expected rates of fragmentation, suggesting there are mechanisms at play that remove <4.75 mm plastic particles from the ocean surface.
