ANGROVE management group The colour of remotely sensed and GIS data in the sustainable management of tropical coastal biocomplexity Farid Dahdouh-Guebas & Nico Koedam Laboratory of General Botany and Nature Management, Laboratory of General Botany and Nature Management, Mangrove Management Group, Vrije Universiteit Brussel, Pleinlaan 2, B-1050 Brussels, Belgium
ANGROVE management group Identification of species/genera (LK) Verheyden, A., F. Dahdouh-Guebas, K. Thomaes, W. De Genst, S. Hettiarachchi & N. Koedam, 2002. High resolution vegetation data for mangrove research as obtained from aerial photography. tonality texture structure shape shade size position
ANGROVE management group Vegetation structure dynamics (LK) Dahdouh-Guebas, F., A. Verheyden, W. De Genst, S. Hettiarachchi & N. Koedam, 2000. Four decade vegetation dynamics in Sri Lankan mangroves as detected from sequential aerial photography : a case-study in Galle. Bulletin of Marine Science 67(2): 741-759. 195619741994
ANGROVE management group Identification of species (LK-KE) IKONOS satellite imageryaerial photography pansharpened BGNIR false colour composite panchromatic new space technology (Ikonos, Quickbird) automated identification extra temporal window 2002
ANGROVE management group Calzadilla Pérez, A., M.C.J. Damen, D. Geneletti & T. Hobma, 2002. Monitoring a recent delta formation in a tropical coastal wetland using remote sensing and GIS. Case study : Guapo River Delta, Laguna de Tacarigua, Venezuela. Monitoring coastal changes (VE)
ANGROVE management group Typification of assemblages/ land cover (KE) Kairo, J.G., B. Kivyatu & N. Koedam, 2002. Application of remote sensing and GIS in the management of mangrove forests within and adjacent to Kiunga Marine Protected Area, Lamu, Kenya.
ANGROVE management group Typification of land cover / assemblages (LK) Jayatissa, L.P., M.-C. Guéro, S. Hettiarachchi & N. Koedam, 2002. Changes in vegetation cover and socio-economic transitions in a coastal Lagoon (Kalametiya, Sri Lanka), as observed by teledetection and ground-truthing, can be attributed to an upstream irrigation scheme. socio-economic survey : use of lagoon water fishermen demography (shell)fish catch
ANGROVE management group De La Ville, N., A.C. Diaz & D. Ramirez, 2002. Remote sensing and GIS technologies as tools to support sustainable management of areas devastated by landslides. Disaster management (VE)
ANGROVE management group Long-term monitoring / integration / forecasting Dahdouh-Guebas, F., J.G.Kairo, L.P. Jayatissa, S. Cannicci & N. Koedam, 2002. An ordination study to view vegetation structure dynamics in disturbed and undisturbed mangrove forests in Kenya and Sri Lanka. Plant Ecology 161(1): 123-135.
ANGROVE management group Research challenges remote sensing and GIS innovation; automated integration of image attributes (texture + structure detection) : have the computer done what until now only the human eye is capable of; long-term monitoring (way beyond the scale of projects with a short duration of 4-5 yrs); parallel complementary research from many disciplines; integration of inter-disciplinary data.
