Abstract River basins sustain ecosystems, which are the main source of water for living and socio-economic development. On the other hand, integrated management refers to various essential management aspects to achieve a sustainable development of river basins. It includes the management of water demand and supply, upstream-downstream linkages, water and land resources development, as well as preserving and restoring the freshwater ecosystem. In this context the Integrated River Basin Management (IRBM), as an alternative and more effective approach to the common fragmented practices, is a concept that is receiving increasing attention. Managing changes from fragmented practices to an integrated approach is a paramount undertaking that a country should anticipated in managing its river basins. These changes in management concept required a capacity development at national level, down to the river basin level. Indonesia, like many other countries, has been gradually implementing capacity...

According to UN estimates that release in March 11th, 2009 the worlds population was projected to exceed nine billion in 2050, up from 6.8 this year and seven billion early in 2012. The additional 2.3 billion are mostly in the developing world, which was estimated to increase from 5.6 billion this year to 7.9 billion in 2050. During the same period population in the developed nations was estimated to rise from 1.23 billion to 1.28 billion. This estimate figure included the projected net immigration that are coming from developing countries at a rate of 2.4 million persons annually from 2009 to 2050. Within the developing countries population for 49 least developed countries is going to be doubled from 0.84 billion to 1.7 billion, while for the rest of third would its population is increasing from 4.8 billion to 6.2 billion during the same period. It should be noted tht the most probable scenario of future direction of fertility rates are its declines from 2.56 children per women in 20...

Flood is a social problem and should be solved as an integrated flood management. Technical or engineering approached, through the construction of civil engineering (physical) infrastructures,  only give a partial solurion.  Mathematical modeling couple with geographic information and communication technology is a tool for integrated flood management, including flood fighting (real time), planning, and development.

A memorandum of understanding (MoU) was signed in December 1st, 2008, between Sarawak River Board (SRB) and Usains Holding Sdn Bhd for Study on Inventory and Monitoring Programme. The study is a year long that focus on Sarawak River, amongst others to enhance the telemetry system, and it will cost Rm 300,000. According to Dr. Stephen Rundi Utom, the Chairman of SRB, budget for study is a federal finance from the Ministry of Natural Resources and Environment. It is expected that more finance will be available for other big rivers in Sarawak. Detailed information on the project components were elaborated by Dr. Lai Sai Hin from the River Engineering and Urban Drainage Research ( REDAC, one of research center from University Sains Malaysia) as follows: To monitor and give warning on river polluting activities, such as illegal dumping To create a river profile for navigational and sediment control, and connect it with a digital network at the SRB headquarters. To develop a network for a...
