ABSTRACT1. This paper provides an introduction to Synthetic Aperture Radar (SAR) remote sensing and, in particular, the significance of long-wavelength (L-band) SAR for wetland applications relevant to the Ramsar Wetlands Convention.2. The Convention has long been a supporter of effective wetland inventory being used to support management initiatives and the wise use of all wetlands.3. Three major application areas have been identified where SAR data may constitute an important additional information source for wetland inventory and management. These comprise mapping of below-canopy inundation, monitoring of environmental disturbances and wetland inventories based on SAR mosaics. These areas have all previously been supported in general terms by formal resolutions on wetland inventory and assessment through the Convention with recognition that further technique development was required.4. The potential to make further use of remote sensing is increased through wider use of the special features of SAR in situations where other data are less suitable.5. The Japanese Advanced Land Observing Satellite (ALOS) provides an opportunity to support the Convention and its goal of wise use of all wetlands.

Although public, governmental, international and stakeholder pressure have led to corporations conforming to better sustainability performance, there has been an insignificant reduction in environmental degradation levels, and progress in sustainable development is limited. This study examines which factors influencing environmental management and reporting in South Africa could potentially contribute to this limited progress. The study was based on a series of interviews with sustainability managers of JSE‐listed firms. Results suggest that stock exchange listing requirements, internal processes and structures, experienced staff and the sustainability committee positively influence environmental and overall corporate sustainability, yet that resource and time constraints, as well as reporting fatigue, potentially limit the advancement of sustainable development. This restricts the further reduction of environmental degradation, which is urgently necessary in light of the harmful impacts that for example climate change has on the environment, societies and economies.
