利用科技开启“蓝色经济”

Today, scientists at the Natural Capital Project share new science and open source software that can calculate risk to coastal¹ and marine² ecosystems³. These novel tools, described in the journal Environmental Research Letters, were used to design the first integrated coastal zone management plan for the Caribbean country of Belize. Conducted with the Coastal Zone Management Authority and Institute in Belize and the World Wildlife Fund, the study offers a comprehensive explanation of the process used to calculate risk of habitat degradation⁴ in marine spatial⁵ planning.

 

With historic expansion of coastal and ocean development, ecosystems like coral reefs and mangrove⁶ forests are put at unprecedented⁷ risk. Yet, planners often lack good information about how human activities will impact shoreline and ocean habitats now and in the future. This study developed the information the Belizean government sought to make informed management decisions. The resulting science and software, which are free and accessible to anyone with a connection to the Internet, are useful to coastal planners anywhere.

 

The integrated ocean management plan paves the way for coastal communities and ocean resources to become the centerpiece of a "blue economy" an economy based on prosperous and sustainable development of coastal societies and natural habitats. The plan would reduce the area of marine habitat at high risk from damaging activities by 20%, while tripling the area available for coastal development, doubling space for marine aquaculture, and reducing controversial oil exploration and dredging.

 

"Healthy marine ecosystems provide necessary habitat for many important marine species and also deliver important services to people, such as tourism, recreation, coastal protection, and food production," says Katie Arkema, lead author of the study and a Stanford University scientist working with the Natural Capital Project. "In Belize, we were able to harmonize development and conservation goals by strategically locating human activities to reduce the area of coral, mangrove and seagrass habitat at high risk while allowing for the expansion of several ocean sectors⁸ of cultural and economic importance. This produced a win-win outcome for the people and environment of Belize."
