“…RUSLE is developed to predict soil loss from agricultural areas. Likewise, the LS factor derived from the digital elevation model (DEM) may not be accurate due to inaccuracies in DEM [69]. In addition, the studied area is located in a tropical climate zone with extreme rainfall and heavy rainstorms which has more potential to erode surface soil [67].…”

This paper evaluates the possible impacts of climate change and land use change and its combined effects on soil loss and net soil loss (erosion and deposition) in the Mae Nam Nan sub-catchment, Thailand. Future climate from two general circulation models (GCMs) and a regional circulation model (RCM) consisting of HadCM3, NCAR CSSM3 and PRECIS RCM ware downscaled using a delta change approach. Cellular Automata/Markov (CA_Markov) model was used to characterize future land use. Soil loss modeling using Revised Universal Soil Loss Equation (RUSLE) and sedimentation modeling in Idrisi software were employed to estimate soil loss and net soil loss under direct impact (climate change), indirect impact (land use change) and full range of impact (climate and land use change) to generate results at a 10 year interval between 2020 and 2040. Results indicate that soil erosion and deposition increase or decrease, depending on which climate and land use scenarios are considered. The potential for climate change to increase soil loss rate, soil erosion and deposition in future periods was established, whereas considerable decreases in erosion are projected when land use is increased from baseline periods. The combined climate and land use change analysis revealed that land use OPEN ACCESSSustainability 2013, 5 3245 planning could be adopted to mitigate soil erosion and deposition in the future, in conjunction with the projected direct impact of climate change.

“…SWAT simulates erosion based on the MUSLE, which is originally developed to estimate annual soil loss from agricultural fields. Also, the topographic factor (LS) derived from DEM may not be accurate due to inaccuracies in DEM (Babel et al, 2011). Jackson et al (1986) and Johnson et al (1986) reported that the MUSLE tends to overpredict sediment yields for small events and underpredict the same for large events.…”

Abstract. This paper evaluates the impact of climate change on sediment yield in the Nam Ou basin located in northern Laos. Future climate (temperature and precipitation) from four general circulation models (GCMs) that are found to perform well in the Mekong region and a regional circulation model (PRECIS) are downscaled using a delta change approach. The Soil and Water Assessment Tool (SWAT) is used to assess future changes in sediment flux attributable to climate change. Results indicate up to 3.0 • C shift in seasonal temperature and 27 % (decrease) to 41 % (increase) in seasonal precipitation. The largest increase in temperature is observed in the dry season while the largest change in precipitation is observed in the wet season. In general, temperature shows increasing trends but changes in precipitation are not unidirectional and vary depending on the greenhouse gas emission scenarios (GHGES), climate models, prediction period and season. The simulation results show that the changes in annual stream discharges are likely to range from a 17 % decrease to 66 % increase in the future, which will lead to predicted changes in annual sediment yield ranging from a 27 % decrease to about 160 % increase. Changes in intra-annual (monthly) discharge as well as sediment yield are even greater (−62 to 105 % in discharge and −88 to 243 % in sediment yield). A higher discharge and sediment flux are expected during the wet seasons, although the highest relative changes are observed during the dry months. The results indicate high uncertainties in the direction and magnitude of changes of discharge as well as sediment yields due to climate change. As the projected climate change impact on sediment varies remarkably between the different climate models, the uncertainty should be taken into account in both sediment management and climate change adaptation.

“…Water footprint concept Water Footprint Evaluation of Oil Palm Fresh Fruit Bunches in Pathumthani and Chonburi (Thailand) J. Mungkalasiri, R. Wisansuwannakorn, and W. Paengjuntuek was first introduced by Hoekstra (2002). It calculates the total fresh water use throughout the life cycle or scope in both direct and indirect use [3]- [8]. It can be expressed in various units such as mass (per ton or kg), time (per hour or year), energy (joule) and even crop (per piece of crop).…”

Abstract-Due to an encouragement of renewable energy, an implantation of oil palm in Thailand is increased. It affects the amount of water consumption in each area. From this point, the aim of this work is to evaluated water footprint (WF) of oil palm fresh fruit bunches using CROPWAT program. The water footprint assessment of fresh fruit bunches in Pathumthani and Chonburi provinces are comparatively studied finding the suitable plantation area in term of water availability. In addition, the appropriate blue water footprint calculation methods and weather data sources are evaluated. The results revealed that Chonburi is more suitable plantation area than Pathumthani. In addition, the results from this study can be used as a water management approach for sustainable agriculture.Index Terms-Oil palm fresh fruit bunches, water footprint, water management.
