Abstract

Development problems of agriculture on border area require handling which more comprehensive and sustainable. Up to now, research results indicate that efforts has been done in handling various problems in agricultural sector, but still partial and is not be able to overcome complex problems. Therefore to overcome various development problems of agriculture on the border area need to be done in holisticaly, covers all aspect i.e. social, economics, ecology, and institution. Sebatik Island is one of state border area between Indonesia and Malaysia, located in Nunukan District, East Kalimantan Province. Up to now, cocoa is still the priority commodity, but its productivity is relatively low. Based on potency and constraint of land resources in Sebatik Island, sustainable recommendations to increase land productivity of cocoa i.e. (1) land and water conservation management, (2) using organic matter, (3) proportional fertilization, (4) using mulch, (5) integrated crop management, (6) integrated crop-livestock system, and (7) improvement of capacity of farmers institution

Abstract

Conversion Conversion and drainage of peat land stimulate soil organic matter (SOM) mineralization, which substantially increase carbon loss from soils. Carbon losses from peat lands are probably a major component in global greenhouse gas emissions. The objectives of this study are to evaluate carbon loss from several land use of peat drained, and to evaluate factors affected carbon loss from several land use on peat drained. The study was conducted in Nanggroe Aceh Darussalam Province from May 2008 until October 2009. Carbon losses were calculated by interpretation data of bulk density (BD), ash content and carbon content from 0-50 cm top soil of peat lands. Peat lands characteristics i.e. physical, chemical and biological properties were investigated by field observation and analysis of peat soil samples on the laboratorium. The results showed that: 1) ash content and bulk density of the peat are related, indicating the partial lost of soil C during decomposition and compaction, 2) an ?internal tracer? estimate of peat C loss yields estimates of CO2 flux up to 56 t CO2-eq ha-1 year-1 for young oil palm, highly correlated with the measured rates of subsidence of the surface, 3) landscape level variation in maximum water table, salinity and Fe of peat are correlated with measured peat carbon loss.
