climate change and its possible impacts on the environment and socio-economic systems now constitute the most important environmental problem facing mankind in the 21st century. climate change will increase poverty and hardship, endanger food security, destabilize economies, decrease food and water and create social insecurity in many countries and undermine our goals for achieving sustainable ...
This chapter explores the relationship between an equitable sharing of emission abatement targets between developed and developing countries and their incentives to participate in an international agreement to control climate change. Although developing countries face a drastic increase in their emissions, environmental efforts are not ranked among their priorities. The obvious explanation is t...
Understanding the resilience of vulnerable sectors of social-ecological systems is critical in an era of escalating global change. The coral reef tourism sector is highly vulnerable not only to ecological effects of climate change and other anthropogenic disturbances on reefs, but also to shocks such as economic recession and energy price escalation. Commercial tourism enterprises are key playe...
Given the large uncertainties regarding potential damages from climate change and the significant but also uncertain costs of reducing greenhouse emissions, the debate over a policy response is often framed as a choice of either acting now or waiting until the uncertainty is reduced. Implicit behind the “wait to learn” argument is the notion that the ability to learn in the future necessarily i...
the present study aims to simulate the spatial pattern of land use change in lisar protected area,iran. land cover maps for 1989, 2000, and 2007 were depicted using tm, etm+, and irs liss-iii images ofthe area at stake. images were classified using a merge of unsupervised and supervised classification. camarkov model was used to predict land cover maps as a top-down approach in investigating la...
In this paper we develop an economic growth model that includes anthropogenic climate change. We include a publicly funded research sector that creates new technologies and simultaneously expands the productivities of existing technologies. The environment is affected by R&D activities both negatively, through the increase of output from productivity growth, as well as positively as new technol...
This paper uses annual variation in climate to examine the impact of temperature and precipitation on national economies. We find three primary results. First, higher temperatures substantially reduce economic growth in poor countries. Second, higher temperatures appear to reduce growth rates, not just the level of output. Third, higher temperatures have wide-ranging effects, reducing agricultu...
The Institute of Hydrophysics of GKSS Research Center is developing the tools and expertise required for both past reconstructions and future predictions of substance fluxes on a regional scale and over a period of several decades, and to evaluate their impacts to society. The goal is to build our capacity to compare between scenarios, be it scenarios of substance-emission regulations, economic...
