| Summary: | In general, degradation on peatlands is mainly caused by excessive conversion and selection of commodities that cannot grow in wet condition. Conversion of peatlands and extreme canalization have become major threats to peatlands which leads to peat fire, subsidence, flooding, green house emission, as well as economic and social problems.
This study was obtained from literature study on current problems and solutions of degraded peatlands through peatland hydrology restoration by rewetting method (canal blocking) and cultivation of species that do not require drainage.
There are four types of dams that are often used to control water flows, plank dam, composite dam, plastic dam, and sluice. The selection of dam is highly dependent on bio-physical condition, dimensions of canals, peat-topography, availability and accessibility of transportation to the dam site. This research shows that there is strong correlation between canal blocking and the increasing of ground water level, where canal blocking is useful for raising the water table and moisturizing the soil.
In the implementation of paludiculture, the certain species / commodities can survive to wet condition, and also have economic value such as: Metroxylon spp, Nypa fruticans Wurmb, Alseodaphne spp. dan Nothaphoebe spp), dan Shorea spp. In order to survive the type of plants has to be selected and adjusted to the condition of peatlands water level. |
