Definition
Technically watered rice field is a rice field that is watered by technical irrigation, i.e. an irrigation system where the incoming water canal is separated from the outgoing canal so that the supply and distribution of water can be easily controlled. Usually this kind of irrigation method consists of a main, secondary and a tertiary canal, with the main and secondary canals and buildings are built and maintained by the water services/government.
Semi-technical irrigation rice field is a rice field that obtains irrigation from a semi-technical irrigation similar to the technical irrigation system. The water services/government are responsible for the buildings at source in order to organize and measures the water input, but subsequent distribution channels are not organized nor controlled by water services/government.
Public Works simple irrigation rice field is one that obtains water from an irrigation system whose water distribution is not yet constant, but the government (Public Works) has participate in building part of the irrigation channel (e.g. the cost of building the irrigation canal).
Non-Public Works simple irrigation rice field is a rice field that obtains water from an irrigation system that is self-organized by the community or the village irrigation without the interference of Public Works. A temporary rice field that is not used for farming includes rice fields that has not been cultivated for more than a year and less than 2 years.
