This dataset depicts relative erosion rate derived for all land draining above the Mesoamerican reef. It is a function of slope, land cover type, precipitation and soil type. The indicators developed by the Reefs at Risk in the Caribbean project enable detailed comparative analyses of threats on many scales. The Reefs at Risk indicators are a simplification of human activities and complex natural processes. This data set was derived at the World Resources Institute for input to the sedimentation and pollution from watershed based sources threat analysis. Agriculture, though important to economic development and food security, is a source of increased sediment, nutrient, and pesticide runoff. Threats from sedimentation...
Using basins derived from a hydrologically-corrected 30m resolution DEM as a unit for summary statistics, we provide a series of indicators focused on land-based sources of threat within the US Virgin Islands and Puerto Rico. This includes indicators of a) the relative vulnerability of the land to erosion (based on slope, precipitation and soil erodibility); b) the relative erosion potential (REP) of the land, based on the relative vulnerability of the land, coupled with the current land cover type; c) the sediment delivery rate for each basin (percentage of eroded which reaches the river mouth); d) estimated sediment delivery for the basin, given current land use;
This data set was developed for use within the Mining and Critical Ecosystems project by the World Resources Institute. This dataset depicts the social vulnerability of an area based on a function of adult literacy, functional literacy, and income.
To capture cumulative threat in a given location, the four threats in the Reefs at Risk Caribbean analysis - coastal development, marine-based, sedimentation and overfishing - were integrated into a single index - the Reefs at Risk Threat Index.
Grid reflects the estimated frequency of severe thermal stress (NOAA Bleaching Alert Level 2) for decade 2030. Values are a percent (as integer) of the decade in which the grid cell would experience severe thermal stress under an IPCC "business-as-usual" emissions scenario. The specific indicator used in the model was the frequency (number of years in the decade) that the bleaching threshold is reached at least once. Frequencies were adjusted to account for historical sea surface temperature variability. Values range from 0 to 100. See the Reefs at Risk Revisited report and technical notes for more information.
Cruise ship ports in the Caribbean and intensity of visitation. This dataset was created on 24th April 2003 and represents all cruise ports in the Wider Caribbean and the number of calls by cruise ships that are scheduled between 1st May 2003 and 1st may 2004. Cruise ships alter their ports of call from year to year and there are other destinations that have not been included in this dataset, as no ships are scheduled.
This dataset depicts forest fragmentation in central Africa by roads. This dataset includes roads. This study, or Pilot Analysis of Global Ecosystems (PAGE), examines forest ecosystems of the world using a large collection of spatial and temporal data. This study analyzes datasets at the global, national, and subnational levels, and draws on published and unpublished scientific studies. It develops selected indicators that describe the condition of the world's forests, where condition is defined as the current and future capacity of forests to provide the full range of goods and services that humans need and consume.

Agriculture, though important to economic development and food security, is a source of increased sediment, nutrient, and pesticide runoff. Threats from sedimentation and pollution from inland sources were modeled for over 3,000 watersheds discharging into the Caribbean.
This shapefile provides the boundaries and degree of threat of frontier forests across the world, as published in "The Last Frontier Forests: Ecosystems and Economies on the Edge." Frontier forests are defined as being primarily forested; of sufficient size to support viable populations of the full range of indigenous species associated with that particular forest ecosystem given periodic natural disturbance episodes; and exhibiting a structure and composition shaped largely by natural events, as well as by limited human disturbance from traditional activities. Frontier forests are relatively unmanaged, are home to most if not all of the species associated with that ecosystem type, are dominated by indigenous tree...
Reef polygons have been classified by integrated local threats, plus thermal stress and acidification projected to 2050. Values of 0 indicate low threat, 100 indicate medium threat, 1000 indicate high threat, 1500 indicate very high threat, and 2000 indicate critical threat.
This dataset represents polygon coverage of sites included in the inventory of Marine Protected Areas in the Wider Caribbean developed under the Reefs at Risk Caribbean project. The availability of polygon is limited. The full inventory of MPAs for the Wider Caribbean can be found in the accompanying point dataset developed under the project. Points with no polygon coverage are not included in this dataset. This dataset does not represent the full inventory.

Agriculture, though important to economic development and food security, is a source of increased sediment, nutrient, and pesticide runoff. Threats from sedimentation and pollution from inland sources were modeled for about 150 watersheds discharging along the Mesoamerican reef, and associated sediment plumes estimated.
Reef polygons have been classified by all local threats integrated (coastal development, marine-based pollution and damage, watershed-based pollution, and overfishing/destructive fishing. Values of 0 indicate low threat, 100 indicate medium threat, 1000 indicate high threat, and 1500 indicate very high threat.
Used in the national level analysis of the Mining and Critical Ecosystems project for the country of Papua New Guinea.
This dataset shows summary statistics for relative erosion rate (REP), river flow, and sediment delivery estimated for each of over 150 watersheds draining along the Mesoamerican Reef.
Cruise ship ports in the Caribbean and intensity of visitation. This dataset was created on 24th April 2003 and represents all cruise ports in the Wider Caribbean and the number of calls by cruise ships that are scheduled between 1st May 2003 and 1st may 2004. Cruise ships alter their ports of call from year to year and there are other destinations that have not been included in this dataset, as no ships are scheduled.
Reef polygons have been classified by estimated threat from overfishing and destructive fishing. Threats to coral reefs from overfishing were evaluated based on coastal population density and extent of fishing areas (reef and shallow shelf areas), with adjustments to account for the increased demand due to proximity to large populations and market centers. Areas where destructive fishing occurs (with explosives or poisons) were also included, based on observations from monitoring and mapping provided by experts. Values of 0 indicate low threat, 100 indicate medium threat, 1000 indicate high threat.
