1. Leaf- to field-level compound effects of warm and dry conditions on crops and potential mitigating strategies
Abstract : Ongoing climate change has been threatening global food security. Under climate change, increasing risk of hot and dry conditions (termed compound events) is projected in many agricultural regions. Compound events cause detrimental effects on crops, yet their effects have rarely been quantified based on modeling approach. READ MORE

2. Conceptualizing catchment processes affecting stream chemistry : from basic understanding to practical applications
Abstract : Maintaining good surface water quality is recognized as one of the greatest challenges for future generations. In northern-latitudes, it is predicted that aquatic ecosystems may experience a large climatic change. READ MORE

3. Forest-savanna transitions: Understanding adaptation and resilience of the tropical forest ecosystems using remote sensing
Abstract : Climate and deforestation-induced changes in precipitation drive tropical forest-savanna transitions. However, precipitation alone provides a superficial understanding of the underlying mechanism behind these transitions. This is because our knowledge of how vegetation responds to changes in hydroclimate is fragmented. READ MORE

4. Floodplain remediation in agricultural streams : improved process understanding for reduced eutrophication
Abstract : Anthropogenically modified headwater streams are key pathways for high nutrient and sediment loads from agriculture, sustaining eutrophication and poor water quality in downstream aquatic ecosystems. To address this challenge, stream mitigation strategies are required that complement in-field measures, to intercept internal pollutant loading in streams. READ MORE

5. The influence of multiscale hyporheic flow on solute transport : Implications for stream restoration enhancing nitrogen removal
Abstract : Stream water that flows into and out of streambeds is called hyporheic exchange flow (HEF).It continuously interacts with groundwater and thereby affect the water quality of local streamreaches as well as downstream recipients by providing an environment where solutes andenergy can be retained and degraded.
