Community participation is essential for the management of a watershed, not only in infrastructure, but through the efficient use of water around the watershed both for irrigation and domestic, manufacture wells infiltration in every housing / estates, creating containers rainfall, prevention of erosion on agricultural land by building terraces and planting trees with economic value which will benefit the Watershed as well as for the user community.
In this case the river basin management interpreted as an attempt to control the interrelationships between humans and all its activities with the natural resources of land, water and vegetation in the basin, in order to obtain optimum benefit, sustained in ekossitem matching, in order to obtain optimum benefits then saah the principles of watershed management is togetherness is togetherness of all of its components (stakeholders) of the watershed is concerned, togetherness form of responsibility in keeping the natural resources of land, water and vegetation in the watershed provide optimal and sustainable benefits.
The main problems in watershed management and soil conservation practices related to institutional issues such as:
1) The difference in the value system (value) community with regard to scarcity of resources, so that the handling problems in Java is different from the outside Java.
2) a strong economic orientation is not balanced commitment to environmental protection function which implies the emergence of problems in the implementation of spatial planning.
3) The problem of latent related to agrarian issues and d. Emptiness institutions / agencies controlling the implementation of the program.
According Asdak C. (2007), the biophysical linkages upstream-downstream region of a watershed, things mentioned below should be a concern:
1) Effective Institutional linkages should be able to reflect the biophysical and socio-economic environment in which it operates. If the management activities upstream. DAS will pose a real impact on the biophysical or socio-economic environment in the lower reaches of the watershed the same, hence the need for decentralized watershed management involving upstream and downstream as a single planning and management.
2) Externalities, is the impact (positive / negative) an activity / program or policy that experienced / felt outside the region where the program / policy implemented. The impact is often not internalized in planning activities. It can be argued that the negative externalities may interfere with the achievement of sustainable watershed management for: (1) the public outside the area of activity (spatial externalities), (2) the people living in a certain time period after the intervention ended (temporal externalities), and (3) the interests of the various economic sectors that are off site activities (sectoral externalities).
The strategic role of watershed as the unit of planning and resource management more evident in a watershed moment can not function optimally as a media regulator and guarantor water water quality that is reflected by flooding, drought and high sedimentation rate. In the process, the incident-kejaian is a phenomenon that arises as a result of disruption of the watershed function as an integrated system involving hydrological complexity of the process that applies to watershed. One indicator that the dominant cause disruption of the hydrological function is the formation of critical lands.
