The accuracy of digital elevation models (DEMs) in urban areas is influenced by numerous factors including land cover and terrain
irregularities. Moreover, building artefacts in global DEMs cause artificial blocking of ...
To evaluate conservation interventions, it is necessary to obtain reliable population trends
for short (<10 years) time scales. Telemetry can be used to estimate short-term survival
rates and is a common tool for assessing ...

The negative health and socio-economic impacts of emissions associated with domestic fuel burning are widely recognized. Although
there has been much progress in the provision of electricity to households in South Africa, ...
Ridging South Atlantic high pressure systems (ridging highs) are often accompanied by cut-off low (COL) pressure systems
aloft, but may also occur without them, in which case a linear baroclinic wave would be observed ...
Climate change is acknowledged as one of the greatest environmental and development challenges
society faces. Many organisations are now encouraged to conduct assessments of the
climate risks they will be exposed to over ...
