Though the basic purpose of MPAs is marine ecosystem conservation, the question of their influence on the local economy is often critical since it governs their social acceptability. This paper addresses the
problem of measuring the local economic impact of MPAs, on the basis of a comparative analysis of socio-economic...
Though the basic purpose of MPAs is marine ecosystem conservation, the
question of their influence on the local economy is often critical since it
governs their social acceptability. This paper addresses the problem of
measuring the consequences of creating a marine protected area (MPA) on
recreational extractive and non-extractive uses...
Since the early 1980s, satellite imagery has been commonly used to detect change
in wetlands. The overall objective of this study is to utilize remote sensing and
Geographic Information Systems (GIS) technology to determine the extent of change of
the wetland area and of other land use and land cover...
Antarctic Ice Sheet mass balance and, hence, sea level change is affected by the floating extensions of outlet glaciers and ice streams that take up about 44% of the coastline (Drewry et al., 1982) and are referred to as "ice shelves". Ice sheet mass loss accelerates when these ice shelves...
The mangrove ecosystem has served as a life-support system to large populations of coastal dwellers in Ecuador for many generations. Diverse communities comprised of multi-racial and multi-ethnic groups have formed along the edge of the mangrove forests throughout the Ecuadorian coast. These groups self-identify as being part of an “ancestral”...
Small-scale land acquisitions are transforming long-standing human-land relations in West Africa. In particular, high rates of urban population growth lead to the transfer of land from non-market customary tenure systems to market-based, formal land tenure regimes on the edges of cities. The literature suggests that the conversion process from inalienable...

This paper discusses a new approach to the design of operating systems. We view the jobs or tasks in this system as a number of small independent steps or functions which are sequenced together to produce a desired result. The concepts upon which this operating system is based are drawn...
