About Aljosja Hooijer

Dr. Hooijer has worked in more than 25 countries since 1990, both in Europe and in the tropics. Most of his projects have been multidisciplinary efforts to find solutions for sustainable management of land and water systems, in which he is active as adviser, researcher and often project leader. Core areas of expertise are water resources management and wetland/peatland management. Activities include development of field monitoring systems, data analysis, environmental impact assessments and training.


In recent years, a key activity has been the development of science based management support projects for lowland peatlands in SE Asia, which make up 10% of the region’s land area, for Governments, NGOs and private business. These activities have evolved from process studies (of the hydrological and carbon cycles, in relation to management and ecology) to impact assessments (determining how peatlands are affected by drainage and fires) to practical management and rehabilitation (aiming to reduce these impacts).
