Types of ecosystems:
Irrigated - Area with irrigation facilities supplying water through artificial means like gravity, force/power, pump, etc. Irrigated area become rainfed only, when the irrigation system is no longer operational for the past two (2) years and beyond repair and there is no plan of irrigating the farm.
Rainfed - The area holds standing water but solely dependent on rainfall for its water supply. It may have dikes that retain rainwater.
Upland - Farm land which has no amenities to hold for standing water. It is usually located along elevated lands, along rivers, between hills, hillsides, etc. Though crops planted in this type of ecosystem are drought-resistant and do not require standing water for their normal growth, irrigation by flushing is sometimes practiced to improve the crops' performance especially during the long dry spell.
