Abstract

Mangroves are invaluable resources in the ASEAN region, providing coastal
protection, wood, and fishery resources. While the region supports the world’s
highest diversity of mangroves, many countries have lost 50% of mangroves
in the last 20 years, to conversion and degradation. Mangrove ecosystems
are also sensitive to climate change impacts, particularly sea-level rise. Sea
level rise of 1.5-9.7 mm a-1 is projected by 2099, and mangrove accretion
rates are usually less than this, resulting in dieback at the seaward edge, and
inland recruitment. Rise in temperature and the effects of increased CO2
levels should increase mangrove productivity, and continue expansion of
mangrove species ranges into higher latitudes. UNEP/ GEF/ WWF has
recently developed protocols for mangrove vulnerability assessments,
combining mapping and micro-elevation determination, long term relative sea level
trends, monitoring of mangrove structure, productivity, condition and
human interaction. Climate change adaptation strategies developed include
reduction of stressors, strategic protected areas designation, rehabilitation of
degraded areas, as well as collaboration with local communities to improve
resource use efficiency.
