Taking the spatio-temporal effects of climate change into account for Life Cycle Assessment of prospective scenarios to secure water supplies in agricultural areas.

To cope with climate change, agricultural territories are forced to implement adaptation strategies, including the implementation of irrigation infrastructures. These strategies are deployed over a long term, and their environmental performance may vary in time and space due to climate change. Environmental assessment methods that include spatio-temporal dynamics must be developed to identify long term "no-regret" scenarios.

Prospective Water Supply Mix for Life Cycle Assessment and Resource Policy Support-Assessment of Forecasting Scenarios Accounting for Future Changes in Water Demand and Availability.

Freshwater comes from different sources unevenly distributed over time and space around the world and plays a key role in the planning of all social and economic sectors on a regional scale. In this context, a consistent framework for modeling regional water supply mix (WSmix) at a worldwide scale has already been developed for use in life cycle assessment (LCA). However, changes in water sources, driven by climate and socio-economic changes, will occur, affecting WSmix.

Diffuse and point sources of silica in the Seine River watershed.

Dissolved silica (DSi) is believed to enter aquatic ecosystems primarily through diffuse sources by weathering. Point sources have generally been considered negligible, although recent reports of DSi inputs from domestic and industrial sources suggest otherwise. In addition, particulate amorphous silica (ASi) inputs from terrestrial ecosystems during soil erosion and in vegetation can dissolve and also be a significant source of DSi.
