Abstract

Today, about half of the world population lives in urban areas and in the coming 20 years, urbanization is expected to increase steadily, especially in the Developing World. Based on UN data and projections, about 4 out of the 5 billion world urban population will live in developing countries by 2030. Large cities in the Developing World face the problem of unplanned growth, coupled with the financial and operational inability to offer the public services needed to sustain a decent life in urban environments. Water is one of those essential commodities which is often short in supply and/or of low quality. Additionally, flood poses a threat to urban dwellers during rainy season. The water management challenges in tropical urban areas today and in the decades to come can be characterized by (1) fighting physical shortcomings in water resources, (2) coping with contamination of groundwater, rivers, lakes, and reservoirs by domestic, agricultural or industrial waste and waste water, (3) mitigating environmental impacts of water extraction (such as loss of wetlands, subsidence and seawater intrusion) , (4) preventing / mastering flood situations and (5) overcoming administrative and financial strains and operational incapacities. Solutions to the problems of urban water in 20 years time are to be found in supply side and demand side measures. The first group includes (1) optimal use of surface water and groundwater resources, (2) pollution protection, (3) watershed management and (4) more water storage. The second group includes (1) educational training, (2) technological innovation, (3) water conservation and (4) water pricing.

Abstract

Through rapid deforestation, forest fires, degrading peatlands, and diminishing carbon ‘sinks’ Indonesia is one of the main contributors to the phenomenon of Global Climate Change. On the other hand, Indonesia will also be a major victim of Climate Change. The combination of high population density on some islands and high levels of biodiversity, together with 80,000 kilometres of coastline and 17,500 islands, makes Indonesia one of the most vulnerable countries to the impacts of Climate Change. Experts expect a warming from 0.2 to 0.3°C per decade in Indonesia during this century, together with an increase in annual precipitation across the majority of the Indonesian islands. Additionally there will be a change in the seasonality of precipitation; Borneo may become 10 to 30% wetter by the 2080’s during December-February. As rainfall decreases during critical times of the year this translates into higher drought risk, consequently a decrease in crop yields, economic instability and drastically more undernourished people. On the other hand, increased rainfall during already wet times of the year will lead to high flood risk. Rising sea levels and many more extreme weather events will contribute to the many problems caused by Global Climate Change. Indonesia, and Kalimantan in the first instance, has to take up the challenge of climate change in taking actions at all levels to reduce greenhouse gas emissions, including promoting sustainable use of land and water resources, and putting adaptation into the development agenda.
