Management areas Bonaire

Map of management areas for Bonaire. The management areas are projected on top of the Bonaire landscape map (see details here) to emphasize the diversity within a management zone. To maintain the diversity present, it is important to recognize these differences when developing and implementing management strategies.

Remote Sensing Tools to support NEXUS challenges

Smalls islands are especially vulnerable to climate change and land  use changes due to the competing needs for limited resources. To support the NEXUS approach we need evidence based monitoring tools that can provide policy makers, conservation managers, entrepeneurs, scientists and the general public with information on the state, pressures and associated changes in the environment. Satellite imagery can provide synoptic information at appropriate
spatial and temporal resolutions that can support evidence based monitoring. Only at very detailed levels information might be added by using airplanes or drones. Remotely sensed information can help to provide information on e.g. land cover and associated dynamics such as urban sprawl, mapping habitats such as mangroves and coral reefs, surveying terrain conditions such as soil moisture conditions and erosion hazards associated within catchments, sea level rise and changing coastlines, and on many aspects of the vegetation (natural and agriculture), such as plant traits, phenology and plant growth. Remotely sensed information can in general make field surveys and monitoring more effective, and can thoroughly support decision making.

3D reef model of Curacao

In 2014 a part of the Curacao reef was captured by underwater photography. From this photo collection a 3D model and an ortho-photo of that part of the reef was constructed. The ortho-photo shows a unique view on the reef that cannot be captured in a single underwater photograph.

Please contact the DCBD administratorfor more information.

Production of Digital Terrain Models for the Dutch Caribbean

Bonaire, St Eustatius and Saba, islands in the Caribbean, became Dutch municipalities in October 2010. These islands are considered hotspots of biodiversity. This brings along specific responsibilities, including a thorough conservation plan. Each plan and monitoring of it demands good basic knowledge and data. It is of great importance for many studies to have proper altitude maps, in addition to good topographical maps. Detailed elevation maps (Digital Terrain Models) are important not only for preprocessing of high resolution satellite imagery , but also for e.g. geomorphological studies, soil surveys, hydrological modelling, species niche modelling, that all need altitude as an important input data layer. At present there are no detailed digital terrain models for these islands, while these are especially important for Saba and St Eustatius that have a very varied and complex topography.
