Research for Mitigating Syndromes of Global Change: Research for Mitigating Syndromes of Global Change. A Transdisciplinary Appraisal of Selected Regions of the World to Prepare Development-Oriented Research Partnerships

The present publication is the final outcome of the "Syndrome Pre-SynthesisProject" (SPSP), a preparatory project initiated in 2001 to pave the way for the NCCR North-South. The SPSP applied a transdisciplinary approach to identify research partnerships for development in 8 regions of the world. The primary aim of the present publication is to present an initial synthesis of core problems in each region, of the status and focus of related research, and of corresponding new research needs. Based on the results of this participatory process, the NCCR North-South programme has followed up on the outcomes of the regional syntheses by identifying future research aims along the general lines determined in the workshops.

The ecoclimatology of Danum, Sabah, in the context of the world's rainforest regions, with particular reference to dry periods and their impact

Climatic records for Danum for 1985 to 1998, elsewhere in Sabah since 1879, and long monthly rainfall series from other rainforest locations are used to place the climate, and particularly the dry period climatology, of Danum into a world rainforest context. The magnitude frequency and seasonality of dry periods are shown to vary greatly within the world's rainforest zone. The climate of Danum, which is aseasonal but subject, as in 1997 to 1998, to occasional drought, is intermediate between less drought–prone north–western Borneo and the more drought–prone east coast. Changes through time in drought magnitude frequency in Sabah and rainforest locations elsewhere in South–East Asia and in the Neotropics are compared. The 1997 to 1998 ENSO–related drought event in Sabah is placed into a historical context. The effects of drought on tree growth and mortality in the tropics are assessed and a model relating intensity and frequency of drought disturbance to forest structure and composition is discussed.
