Remote Sensing

This paper relates to remote sensing of water use and water stress in the African savanna ecosystem at a local scale, as well as the development and validation of a monitoring tool.
Deforestation worldwide could have important consequences for diet quality and human nutrition given the numerous ecosystem services that are provided by forests and biodiverse landscapes. Yet, empirical research assessing the links between deforestation and diets is lacking. In this study, we examined the association between deforestation and diet diversity among children using geolocated Demographic and Health Survey data for 33,777 children across 15 countries of sub-Saharan Africa coupled with remotely-sensed data on forest cover loss.
To establish an estimation procedure for reliable catch amount of illegal, unreported and unregulated (IUU) fishing, light-gathering fishing operations in the northwestern Pacific were analyzed based on the Visible Infrared Imaging Radiometer Suite (VIIRS) day/night band (DNB) data provided by the Suomi National Polar Partnership (SNPP) satellite. The estimated fishing activities were compared with the navigation tracks of vessels obtained from the automatic identification system (AIS).
Using newly-released and globally available high-resolution remote sensing data on forest loss, we update the assessment of the cross-country determinants of deforestation in developing countries. We validate most of the major determinants found in the previous literature, generally based on earlier time-periods, except for the role of institutional quality. Agricultural trade, hitherto relatively neglected, is found to be one of the main factors causing deforestation.
One mechanism by which land use change influences biodiversity and ecological processes is through changes in the local climate. Here, the relationships between leaf area index and five climate variables - air temperature, relative humidity, vapour pressure deficit, specific humidity and soil temperature - are investigated across a range of land use types in Borneo, including primary tropical forest, logged forest and oil palm plantation.
