Savanna ecosystems comprise 22% of the global terrestrial surface and 25% of Australia (almost 1.9 million km2) and provide significant ecosystem services through carbon and water cycles and the maintenance of biodiversity. The current structure, composition and distribution of Australian savannas have coevolved with fire, yet remain driven by the dynamic(More)
Effective monitoring is necessary to conserve mangroves from further loss in Malaysia. In this context, remote sensing is capable of providing information on mangrove status and changes over a large spatial extent and in a continuous manner. In this study we used Landsat satellite images to analyze the changes over a period of 25 years of mangrove areas in(More)
Research on atmospheric aerosols has become an important component in atmospheric studies due to its tremendous implications to radiation budget, climate change, hydrological and carbon cycles. Several recent studies have analysed the spatio-temporal patterns of aerosols and their relationship with meteorological conditions which is essential to quantify(More)
The current approach that has been adopted in remote sensing education at the Universiti Teknologi Malaysia (UTM) is presented in this paper. A systematic formulation of syllabus that addresses cognitive learning issues, the integration of remote sensing with other related technologies, opportunities to conduct research, undergoing training and promoting(More)
Gross primary productivity (GPP) is a critical flux determining the quantity of carbon entering an ecosystem. Thus, studying GPP at larger spatial and longer time scales is necessary to identifying locations of potential sinks or sources of carbon. This study employs remote sensing techniques to estimate savanna GPP in the Northern Territory (NT), Australia(More)
