In this study, we investigated the impact of climate change on streamflow and water quality (TSS, T-N, and T-P loads) in the upper Dong Nai River Basin using the Soil and Water Assessment Tool (SWAT) hydrological model. The calibration and validation results indicated that the SWAT model is a reasonable tool for simulating streamflow and water quality for this basin. Based on the well-calibrated SWAT model, the responses of streamflow, sediment load, and nutrient load to climate change were simulated. Climate change scenarios (RCP 4.5 and RCP 8.5) were developed from five GCM simulations (CanESM2, CNRM-CM5, HadGEM2-AO, IPSL-CM5A-LR, and MPI-ESM-MR) using the delta change method. The results indicated that climate in the study area would become warmer and wetter in the future. Climate change leads to increases in streamflow, sediment load, T-N load, and T-P load. Besides that, the impacts of climate change would exacerbate serious problems related to water shortage in the dry season and soil erosion and degradation in the wet season. In addition, it is indicated that changes in sediment yield and nutrient load due to climate change are larger than the corresponding changes in streamflow.

This study sought to investigate the impact of climate change on livestock production at the Mpolonjeni Area Development Programme in Swaziland. Primary data were collected using an interview schedule from 323 sampled households. Climate data were collected from the Swaziland Meteorology Department and Livestock data were collected from the Ministry of Agriculture. Perceptions of households and climate data were used to establish climate patterns in Mpolonjeni Area Development Programme. The Recardian regression model and descriptive statistics were used to establish the impact of climate change on livestock production. A total of 99.4% of the respondents suggested that temperatures were increasing whilst 98% felt that rainfall patterns were erratic. About 95% of the respondents have experienced drought at some point in time. Results of the Ricardian model showed that goats net revenue was sensitive to winter temperature, winter temperature squared, winter rainfall and winter rainfall squared. The study concludes that climate change impacts negatively on livestock production and thus livestock owners need touseclimate change adaptation strategies, adapt especially when it comes to drinking water sources for the animals. In case of poor rainfall, farmers need to provide their animals with drinking water. Government should assist livestock farmers with reliable water sources such as canals and dams.
