Abstract The main purpose of this study was to estimate possible climate change effects on the annual streamflow of Filyos River (Turkey). Data for annual streamflow and climatic parameters were obtained from streamflow gauging stations on the river and Bartın, Karabük, Zonguldak meteorological observation stations. Time series analysis was performed on 46 years of annual streamflow data and 57 years of annual mean climatic data from three monitoring stations to understand the trends. Pettitt change-point analysis was applied to determine the change time and trend analysis was performed to forecast trends. To reveal the relationship between climatic parameters and streamflow, correlation tests, namely, Spearman's rho and Kendall's tau were applied. The results of Pettitt change-point analysis pointed to 2000 as the change year for streamflow. Change years for temperature and precipitation were detected as 1997 and 2000, respectively. Trend analysis results indicated decreasing trends in the streamflow and precipitation, and increasing trend in temperature. These changes were found statistically significant for streamflow (p < 0.05) and temperature (p < 0.01). Also, a statistically significant (p < 0.05) correlation was found between streamflow and precipitation. In conclusion, decreasing precipitation and increasing temperature as a result of climate change initiated a decrease in the river streamflow.

The current study was conducted in Bara Locality- North Kordofan - Sudan to assess climate change adaptation and mitigation strategies among agrarian communities. Qualitative and quantitative data were collected by randomly interviewing 150 respondents from ten villages, using questionnaire. Descriptive statistics in SPSS software package and Microsoft Excel were used for data analysis. Results of study showed that agrarian communities, and due to climate change, have enforced to develop ten adaptation strategies suitable for agriculture in dryland conditions. The most adaptation strategies being used by the agrarian communities, are cultivation in different directions locally Sheraik (77%), sowing before rain locally Ramail (77%) and reducing cultivated area as mentioned by 67% of interviewed respondents. In forests sector, around 65 % of the interviewed respondents have been practiced agro-forestry as an adaptation strategy. The interviewees were also able to figure out 6 possible mitigation strategies to stave off climate change effects. These strategies are for example building capacity of agrarian communities (73%) and provision of early mature, high yielding and drought tolerant crops (63%). The study come out with some suggestions in order to pave the way for policymakers to tailor suitable future interventions to mitigate the impact of climate change among agrarian communities.
