Chapter
Wetlands are among the most vulnerable, threatened, valuable, diverse, and heterogeneous ecosystems existing on our planet. While they provide invaluable ecosystem services to our society, they have been declining globally for many centuries. Monitoring of these changes is necessary for implementing efficient conservation policies and sustainable m...
Article
Full-text available
Climate change, increasing population and changes in land use are all rapidly driving the need to be able to better understand surface water dynamics. The targets set by the United Nations under Sustainable Development Goal 6 in relation to freshwater ecosystems also make accurate surface water monitoring increasingly vital. However, the last decad...

Achieving the objectives of the Ramsar Convention requires access to global, up-to-date, and reliable information to complete national wetland inventories and to undertake adequate assessment and monitoring, and establish appropriate management and restoration plans. The use of satellite Earth Observations (EO) with innovative geo-spatial analyses...
Article
Remote sensing studies of vegetation phenology increasingly benefit from freely available satellite imagery acquired with high temporal frequency at fine spatial resolution. Particularly for heterogeneous landscapes this is good news, given the drawback of medium-resolution sensors commonly used for phenology retrieval (e.g., MODIS) to properly rep...

Heat waves are projected to become more frequent, longer-lasting, and intense. At the same time, urban areas are confronted with the urban heat island (UHI) phenomenon, which adds to the thermal stress experienced during hot spells. Focusing on the Paris area during the hot summer of 2003, we investigated the influence of heat waves on UHI intensit...

The Urban Heat Island (UHI) effect is a typical phenomenon of urban climate, where the temperature of central urban locations is several degrees higher than that of surrounding rural areas of similar elevation; the temperature difference is especially pronounced during night-time. Although the UHI effect has long been studied through ground-based o...
Conference Paper
Urban Heat Island (UHI) is an urban climate phenomenon, which is described by the occurrence of temperatures that are higher over urban surfaces than over surrounding rural areas of similar elevation. The phenomenon is particularly pronounced during night-time. UHI is primarily driven by the shortwave incoming radiation energy reaching the urban su...
