Catchment processes in Southeast Asia: Atmospheric, hydrologic, erosion, nutrient cycling, and management effects

Recognizing the importance of catchment processes related to the long-term sustainability of rapidly developing forested and formerly forested landscapes in tropical Asia, two scientific meetings were recently hosted to highlight current research advances in this region. Here we have compiled 18 papers that address various catchment processes in tropical Asia, including atmospheric fluxes, hydrologic and geomorphic processes, and carbon and nutrient cycling, as well as related land management effects. Sustainable management options related to catchment processes in Southeast Asia are discussed herein, along with research and technology transfer needs. A conceptual model is presented for assessing the interactions of anthropogenic factors on catchment processes across various temporal and spatial scales.
