  Abstract As the water issue relates the carbon issue in peatland, carbon and water interrelation has been studying for long term (more than 10 years) in peatland of Central Kalimantan, Indonesia. The Soil Moisture Content (SMC) and Ground Water Table (GWT) in long term have been monitoring by auto-monitoring system called SESAME, developed by our team, and Net Ecosystem Exchange (NEE) has been measured by Eddy Covariance on the tower. By these long-term monitoring, it is found that a) positive correlation with SMC and GWT, b) negative correlation with NEE and GWT. On the other hand, as global soil moisture data has been provided daily from European Center for Medium-Range Weather Forecasts (ECMWF), we developed mapping model on GWT and NEE, applying correlation coefficient of SMC-GWT and NEE-GWT. The NEE mapping in peatland corresponds with Tier 2 and 3 level of Intergovernmental Panel on Climate Change (IPCC) guideline.    Read More about this Ar...

  Abstract Land is the essential component which provides us food, shelter, and fiber. It is non-renewable resource which is degraded day by day. Some major factors like climatic, natural and anthropogenic deteriorate quality of land and degraded it for agriculture use. Agriculture sector is directly linked with land while most of the agriculture land is degraded by some factors. Due to rapid changes in climatic conditions, deforestation, desertification, erosion, salinization, waterlogging, and organic matter depletion lead to land degradation. For restoration of land, it is important to minimize these activities and properly managed all factors. We can manage our land by ground covers, alternate fuels, timber replantation, dams and by making the policies. Furthermore, organic agriculture may be an alternative to save our land from degradation. The present review focuses on effect of land degradation on agriculture and environment; and how we can manage our lands f...
