|Abstract||The topic of biodiversity loss has been the subject of a vast and growing scientific and economic literature. Species are estimated to be going extinct at rates 100 to 1000 times faster than in geological times. Globally, terrestrial biodiversity is projected to decrease by a further 10% by 2050. As with biodiversity, the planet has also experienced major losses in the services derived from ecosystems. During the last century, for example, the planet has lost 50% of its wetlands, 40% of its forests and 35% of its mangroves. Around 60% of global ecosystem services have been degraded in just 50 years. While there is a large and growing literature on the values associated with the services that ecosystems provide, much less has been done in analysing the causality in the other direction – i.e. in assessing the linkages from changes in ecosystem services to the functioning of the economy. This report contributes to an effort to identify environmental pressures under different structural and environmental policy assumptions and the associated damages that will result under different economic scenarios to 2050. Based on these it aims, inter alia, to examine how the environmental pressures may affect economic growth paths. This report contributes to that goal by looking at the consequences of the loss of biodiversity and ecosystem services. It does so by reviewing the main findings in the literature and key issues involved in the valuation of biodiversity and ecosystems services, as well as key issues involved in linking loss of biodiversity and ecosystems services to economic activity. The report finishes by identifying the main opportunities and obstacles in including biodiversity and eco-system services into a dynamic general equilibrium framework.|
|Learning Resource Type||Article|
National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
