Abstract
The swamplands is one of the prospective suboptimal land for agriculture. The land consists of tidal swamplands and freshwater land which are widely available in Indonesia. The hydrotopography of tidal swampland is strongly influenced by tide and neap of water, while in freshwater land it is largely determined by rainfall. Drought, flooding or deep inundation, and shifts in rainfall patterns as a result of extreme climate change have an impact on agriculture in decreasing food crop production, particularly for rice in swamplands. One strategy in anticipating the impact of climate change in agriculture, especially food crops (rice) is to use submergence and drought tolerant varieties as well as early maturing rice varieties. Rice varieties tolerant of submergence in swamplands such as Inpara 3, Inpara 4, Inpara 5, Inpari 29, and Inpari 30 Ciherang sub1. While drought tolerant varieties such as Inpari 18, Inpari 19, Inpari 20, Inpago 4, Inpago 5, Inpago 6, Inpago-8, and Inpago Lipigo-4. In addition to avoiding drought, early-maturing aged rice varieties such as Hipa 6 Jete, Inpari Si Denuk can be used, Inpari-34 Salin Agritan, Cakra Buana Agritan, Inpari 12 and Inpari 13. The purpose of this paper is to describe how to reduce the impact of climate change on swampland agriculture by planting submergence and drought tolerant rice varieties. By using submergence and drought tolerant varieties and early maturing varieties, it is expected to reduce and anticipate the impact of climate change, particularly for agriculture on swamplands.
