This research aims to monitor the hydrological drought trends within geographical confines of Ethiopia, Sudan, and Egypt in Blue Nile River Basin. Historical circumstances basin were analyzed through utilization stream flow index (SDI). The long-term historical trend was investigated via application Mann – Kendall Sen (MK) test. Streamflow data collected at border (GERD) (Ethiopia) Khartoum Dongola (Sudan) spanning period from 1900 2001. Four distinct temporal scales examined, including monthly (SDI1), seasonal (SDI3), bi-annual (SDI6), annual (SDI12) frequency. Notably, SDI1, SDI3, SDI6 exhibited a higher frequency occurrences, whereas SDI12 demonstrated lower frequencies, accompanied by longest duration all gauged stations. For preceding 102-year period, two extreme events identified across stations: 1912/1913 1913/1914 Border stations, 1986/1987 station. Moreover, results revealed that severe manifested three, six, four times, Border, Khartoum, respectively. Furthermore, an investigation patterns led conclusion does not pose imminent threat downstream nations, Sudan. However, analysis increasing observed Autumn season while positive characteristic wet condition remaining seasons. Annual did show any statistically significant findings. Nevertheless, study highlighted imperative role soil water conservation measures upstream countries, such as Ethiopian highlands, mitigating prolonged effects meteorological which gradually propagates into drought. Consequently, nations must engage cooperative efforts with countries address this issue collectively, rather than bestowing sole responsibility on latter.

Water availability is an important aspect of life. With the increasing number humans with same water cycle, it possible that scarcity will occur, including in Bandung City, especially Jatisari Village, Buahbatu District. Public awareness and regulation use are required. This study aims to analyze influence environmental communication on community behavior intervening variable cognitive dissonance household Village; explore carried out what obstacles are; also scope policies City. uses a mixed method analysis using SPSS 25 ATLAS.ti 23.1. The results Sobel test showed mediation coefficient 0.0288 was significant, which means has significant mediating relationship between perceptions for behavioral change. Meanwhile, City Government non-Bandung maintain sustainability shown collaboration involving various stakeholders. Although there much progress, still need be overcome, coordination actors public awareness. Also, six were found but no policy specifically regulates conservation, distribution, limits support availability. likely due absence parameters can convince government make example, through Scarcity Assessment Index.

The Tumen River Basin (TRB), a critical China border region, has experienced complex evolution of runoff due to climate change and human activities. This study aims quantify the main drivers variations in TRB based on Budyko framework assess relative contributions activities fluctuations. Results indicate pronounced warming increased precipitation TRB, while exhibits declining trend with temporal variability. Runoff decreased during 1956–1980 but post 1980. Overall, is dominant factor driving fluctuations TRB. A comparison across different sub-basins shows that contribution higher middle upper reaches River, reaching up 93.8%. In lower basin, contribute significantly variations. Higher forest cover reservoir construction help maintain long-term stability watershed runoff. provides scientific basis data support for water resources development ecological protection basin.
