A multi-source water balance modelling approach driven by satellite data was used to operationally monitor daily water level fluctuations across the pastoral regions of northern Kenya and southern Ethiopia. Advanced Spaceborne Thermal Emission and Reflection Radiometer data were used for mapping and estimating the surface area of the waterholes. Satellite-based rainfall, modelled run-off and evapotranspiration data were used to model daily water level fluctuations.

Africa's renewable energy power potential is substantially larger than the current and projected power consumption of the continent. Local geothermal, solar thermal and bioenergy resources have an important role to play in covering future heat demand. Domestic biofuels and renewable energy-based electrification of urban public transport can contribute significantly to transport needs.

GIZ (former GTZ) Proklima has compiled this publication to provide information on natural foam blowing agents as ozone- and climate-friendly alternatives to HCFCs. The first section of the book covers policy-related aspects of technology transition towards natural foam blowing agents and examines the impact legislative changes have on development and adoption of alternative technologies. The second part deals with the use of natural blowing agents in rigid and XPS foam, the conditions for conversion and special technologies. Part 3 comprises case studies from developing countries.
