It is the most important economic zone in this part of the country, with a strong timber industry, agriculture and hydroelectricity. The catchment also boasts the country’s third-largest river port, located in the town of Ouesso. Unfortunately, increasingly frequent low-water levels in recent years have led to a decline in river navigation and economic activities. So, the aim of this study is to show the effects of climate change over the last six decades in the Sangha watershed at Ouesso hydrological station, located in the north of the Republic of the Congo-Brazzaville, and elucidate its impact on water resources. To achieve this, several statistical and hydrological methods were used. The application of change-point or shift detection tests to flow series from 1961 to 2020 revealed variability in the hydrological cycle, characterized by two major phases of homogeneous flows: a wet surplus phase and a dry deficit phase. The results show one shift in flood flows in 1971 (Buishand test), one shift in yearly average flows or modules in 1971 (Pettitt test and Buishand test), and one shift in low-water flows in 1976, with all two tests. These disruptions were accompanied by a drop in flow of around 15.63%, 21.70% and 35.67%, on average, for floods, modules, and low-water, respectively, a drop in rainfall of around 9.6% and a rise in temperature of around 0.76?C. These flows show an overall downward trend. The calculated recession coefficients show that, over the entire study period, a recession occurred in March 1985.展开更多

A.D. could serve as an example of the unique history of interaction between Buddhism and Japanese autochthonous religion Shinto. The first Buddhist Sangha in Japan, at the same time was also a female Buddhist community of nuns in this country. It could be assumed that the choice of the women, designed to embody the Dharma in Japan, was not accidental and was driven by the perception of the Buddha image at the time of its introduction in Japan in VI century, especially to compare with the hagiographies of Tibetan yoginis （Machig LabdrSn, Yeshe Tsogyal） and Chinese nuns （＂Bikuni Zhuan＂） of V-VII cc. With a number of similarities （persecutions of the anti-Buddhists, desire to receive a full knowledge of Dharma）, the information of the first Japanese nuns still differ considerably from the hagiographies of yoginis and Chinese Buddhist nuns. The activity of first Japanese nuns, consisted in the worship of the statue of the Buddha, rather remind the shamanistic responsibilities of the Shinto priestesses, who were the intermediates between people and gods. This is reflected in the early Japanese description of Buddhist monks and nuns in Nihon ShOki, Gangoji Garan Engi and Nihon ryOiM as the Shamanistic priests and guardians of the Buddha-imase with a special magical status, rather than the preachers of Dharma, in comparison with the Tibetan and Chinese sources.展开更多
