Climate Change

Restoring forest cover is a prominent option for climate mitigation. Effective deployment requires knowing where opportunities are and how they vary in carbon capture, costs, co-benefits, and feasibility. Here, we combined spatial, economic, and feasibility analyses to examine 10 different opportunity classes for restoration of forest cover across the contiguous United States. These include non-stocked forests, shrublands, protected areas, post-burn landscapes, pasture lands, croplands with challenging soils, urban areas, floodplains, streamsides, and biodiversity corridors.
The demand-supply balance of electricity systems is fundamentally linked to climate conditions.
Background: Various retrospective studies have reported on the increase of mortality risk due to higher diurnal temperature range (DTR). This study projects the effect of DTR on future mortality across 445 communities in 20 countries and regions. Methods: DTR-related mortality risk was estimated on the basis of the historical daily time-series of mortality and weather factors from Jan 1, 1985, to Dec 31, 2015, with data for 445 communities across 20 countries and regions, from the Multi-Country Multi-City Collaborative Research Network.
With ongoing global climate change and human activities, increasing desertification plays a predominant role in increasing soil nutrient losses. Soil nitrogen (N) is the essential limiting nutrient supporting plant growth and evaluating soil nutrient content, especially in desert ecosystems. N microbial processes will ultimately restore and maintain the balance in the soil N cycle, but the damage caused by desertification to soil N functional microorganisms associated with N supply, transformation, and loss is poorly understood.
Deterioration of water quality due to economic development, climate change and other factors has become a challenge to human beings and the ecosystem. Most countries have recognized this problem and have resorted to actions for improving water quality. However, the effect on water quality improvements due to these actions is uncertain due to the plausibility of multiple scenarios like climate change scenarios and socio- economic scenarios.
Cities are wrestling with the practical challenges of transitioning urban water services to become water sensitive; capable of enhancing liveability, sustainability, resilience and productivity in the face of climate change, rapid urbanisation, degraded ecosystems and ageing infrastructure. Indicators can be valuable for guiding actions for improvement, but there is not yet an established index that measures the full suite of attributes that constitute water sensitive performance.
Meat consumption has been increasing since the 1960s, but especially from the 1980s decade to today. Although meat means an important source of nutrients, it is also evident that a great consumption of this source of proteins has also a negative environmental impact. Livestock production does not only have a negative influence on GHG emissions, but also on the water footprint, water pollution, and water scarcity.
Climate change is reshaping the comparative advantage of regions and hence driving migration flows, principally toward urban areas. Migration has multiple benefits and costs in both origin and destination regions. Coordinated policies that recognize how and why people move can reduce future costs and facilitate adaptation to climate change both within borders and internationally.
