1Climate is changing and evidence suggests that the impact of climate change would influence our everyday lives, including agriculture, built environment, energy management, food security and water resources. Brunei Darussalam located within the heart of Borneo will be affected both in terms of precipitation and temperature. Therefore, it is crucial to comprehend and assess how important climate indicators like temperature and precipitation are expected to vary in the future in order to minimise its impact. This study assesses the application of a statistical downscaling model (SDSM) for downscaling General Circulation Model (GCM) results for maximum and minimum temperatures along with precipitation in Brunei Darussalam. It investigates future climate changes based on numerous scenarios using Hadley Centre Coupled Model, version 3 (HadCM3), Canadian Earth System Model (CanESM2) and third-generation Coupled Global Climate Model (CGCM3) outputs. The SDSM outputs were improved with the implementation of bias correction and also using a monthly sub-model instead of an annual sub-model. The outcomes of this assessment show that monthly sub-model performed better than the annual sub-model. This study indicates a satisfactory applicability for generation of maximum temperatures, minimum temperatures and precipitation for future periods of 2017–2046 and 2047–2076. All considered models and the scenarios were consistent in predicting increasing trend of maximum temperature, increasing trend of minimum temperature and decreasing trend of precipitations. Maximum overall trend of Tmax was also observed for CanESM2 with Representative Concentration Pathways (RCP) 8.5 scenario. The increasing trend is 0.014 °C per year. Accordingly, by 2076, the highest prediction of average maximum temperatures is that it will increase by 1.4 °C. The same model predicts an increasing trend of Tmin of 0.004 °C per year, while the highest trend is seen under CGCM3-A2 scenario which is 0.009 °C per year. The highest change predicted for the Tmin is therefore 0.9 °C by 2076. The precipitation showed a maximum trend of decrease of 12.7 mm year. It is also seen in the output using CanESM2 data that precipitation will be more chaotic with some reaching 4800 mm per year and also producing low rainfall about 1800 mm per year. All GCMs considered are consistent in predicting it is very likely that Brunei is expected to experience more warming as well as less frequent precipitation events but with a possibility of intensified and drastically high rainfalls in the future.

cover-led-stlighting-practicesProviding street and public lighting is one of the most expensive responsibilities of a municipality. This report presents lessons from a pilot LED project in Indonesia.

Providing street and public lighting can account for up to 38% of energy consumption and greenhouse gas emissions in some cities. New energy-efficient technologies and design can cut street lighting costs dramatically (up to 60%) and reduce greenhouse gas emissions by the same amount. These savings can reduce the need for new generating plants and redeploy scarce capital to delivering energy access to populations in remote areas. The savings also allow municipalities to expand street lighting coverage to additional areas that include low-income and other underserved areas.

Recognizing the opportunity to provide more efficient street lighting in Indonesia, the Pilot LED Project successfully demonstrated significant savings and developed new specifications for LED luminaires that focused on luminaire performance, quality of delivered illumination, and vendor qualifications. The new specifications were localized from international best practices and then used for the procurement and retrofit of 1,439 LEDs in two municipalities in Central Java as well as several power generating and substation facilities in West Java.

With a view toward scaling up the efforts of the Pilot LED Project and supporting larger energy efficiency projects in municipalities throughout Indonesia, this report aims to describe lessons learned during the implementation of the Pilot LED Project, identify possible financing options for future municipal street lighting projects, and offer technical and policy recommendations.

cover-pages-wateruse-remote-sensingThis brief discusses remote sensing technology as a powerful tool in understanding basin water resources.

In a pioneering collaborative study, a research team from IHE Delft Institute for Water Education is working closely with ADB operations departments using remote sensing to understand how water resources are used in project sites in six countries: Cambodia, India, Indonesia, Pakistan, Sri Lanka, and Viet Nam. 

Using remote sensing technology, for the first time water productivity can be measured right down to the farm level. For years, the limitation has always been the lack of data. With remote sensing technology, this will no longer be an issue.

The new window of understanding derived from this technology will be fundamental to sound planning of future water projects.
