Food demand, Productivity Growth and the Spatial Distribution of Land and Water use: A Global Modelling Approach

Nowadays, human society appropriates about one quarter of total net primary production of the terrestrial biosphere. Production of food, energy and materials, and the related use of land and water account for crucial components and interactions in the Earth System. However, rising food, energy and material demand, climate change and ambitious mitigation policies will enhance the competition for land and water. While the combined impacts of these drivers are still highly uncertain, global land-use patterns will change in the future, reacting to these pressures. Projecting their future development is important to study both, their impacts on the Earth System as ...

Climate, Geography and Macroeconomics: Revised Data, Refined Analysis and New Findings

Assessments of social and economic impacts of climate change are primarily based on the results of biophysical climate impact models, which are aggregated, extrapolated and/or valued in monetary terms. Another potential source of information on climate impacts are spatial and/or temporal analogues, such as Ricardian analysis of climate impacts on agriculture. Another recent effort to this end involves the development of the G-Econ database (Nordhaus, 2006), which describes the relationship between climatic and geographic factors on the one hand and regional economic productivity on the other. A multivariate regression derived from this database has been used to estimate global economic ...

The Effect of Thermal Pollution on Benthic Foraminiferal Assemblages, in the Mediterranean Shore Face Adjacent to Hadera Power Plant (Israël)

Over the past several decades public and scientific awareness to global warming has increased significantly. As a result, many studies have examined the affects of global warming. However, the consequences of global warming on marine living organisms at the Levantine basin of the East Mediterranean has not yet been explored. In this study, we have used the thermal pollution of a power plant at the Mediterranean coast of Israel as an analog for the expected future trend of sea surface temperature (SST) rise. We have performed a sequence of 11 sampling campaigns at 5 stations located along a temperature gradient ...

Climatic Hazard Mitigation Through Risk and Resilience Committees in Nepal

Nepal lies in an ecologically fragile and seismic region with a history of devastating Glacier Lake Outburst Flood (GLOF), landslides and earthquakes. Increases in temperature could increase the frequency and magnitude of climatic disaster occurrences. Winter snow in Kathmandu in 2007 after nearly 65 years absence, frequent flood events since 2000, and an increased number of glacier lakes in the upper Himalayas indicates that climate change may already be having a significant impact. Disaster events in Nepal are known to impact disproportionately on poor and marginalised people who live in more exposed environments during risky times and without adequate forms ...
