Research Interests

Human-Environment Systems Analysis: modelling and evaluation of society-environment interactions; application of operations research (OR), multicriterion decision making, soft systems methodologies, conflict analysis, and (neuro)fuzzy modelling to planning and resource management; pluralistic modelling and community OR (modelling across the "knowledge and values divide").

Integrated Land-Water Management: setting instream-flow standards; land-use planning and water (re)allocation under drought and climate change; modelling and management of land-to-water material fluxes; integrating traditional/local and scientific knowledge and values forenvironmental management; development and application of collective decision-making procedures for resource allocation and burden sharing in common-pool resources.

Marine and Coastal Zone Management: coral-reef management; spatial design of marine-management areas.

CURRENT PROJECTS RELATED TO CONSERVATION BIOLOGY :

  • Participatory multiobjective coral-reef management for Cagayancillo, Palawan, The Philippines [in collaboration with World Wildlife FundÑPhilippines (KKP)].
  • Collaborating on the development of scenarios for North Sea management for year 2050; being prepared for the NetherlandsÕNorth Sea Directorate,Rijkswaterstaat.
  • Policy analysis and conservation strategies for Helen Reef, Hatohobei State, Republic of Palau [in conjunction with Community Conservation Network and Palauan partners].
