The main objective of this study was to setup model and evaluate the model performance for streamflow simulation in Burundi using Soil and Water Assessment Tool (SWAT) model. The total area of Burundi is 27,834 ㎢. The elevation of Burundi ranges from 780 m to 2,700m. The West and East are low lands, while the Central part is high land. The topographic data (30 meters Digital Elevation Model) and land use and land cover data of Burundi were obtained respectively from Shuttle Radar Topography Mission (SRTM) and the Regional Centre for Mapping of Resources for Development (RCMRD). The soil data used was obtained from Food and Agriculture Organization (FAO). The local weather data and discharge data were provided by Burundi Hydro meteorological Service (IGEBU). Mean Areal Precipitation (MAP) and Mean Areal Temperature (MAT) were estimated. The streamflow simulation was done for the period 1980-2017. The calibration and validation of river discharge was performed at a daily time step from 2005 through 2011 as the calibration period and 2012 up to 2017 as the validation period. The findings show that streamflow decreases during Jun to September and increases during March to May and October to December.

Access to clean and affordable water is one of the fundamental human rights because water is essential to life and a foundation for socioeconomic development of any country in the world. Despite the efforts to secure water supply in Burundi, the amount of water supplied by public utilities does not meet the demand of the population because population keeps increasing with fluctuation of weather conditions. This study selected north Bujumbura that is a sprawling new residential area in the western part of Burundi as a case to investigate the potential of rainwater harvesting in meeting water demand of the country. Based on a long-term average monthly precipitation in the region, the rainwater harvesting potential was assessed as a function of roof sizes, number of households, and runoff coefficients of roof materials. For the entire region of north Bujumbura, the current water supply capacity of the local water company combined with the rainwater harvesting potential resulted in the water surplus of $468,604.1m^3/yr$. Although three communes among them still showed water deficit in dry season, they still got help from rainwater to relieve their water shortage. This suggests that at the regional scale, proper storages and water quality control for harvestable rainwater could contribute to relieving the regional water shortage and allow the population growth.

Since improper management practices of solid medical waste (SMW) could potentially result in serious health risks and environmental problems, it is very important to properly treat and dispose of the medical wastes. In this study, current practices of SMW management from storage to final disposal stage in 12 health care facilities (HCFs) of Burundi were investigated using the official government reports. The results showed that 75% and 92% of HCFs used uncovered wheelbarrows and trucks for on-site or off-site SMW transportation, respectively, indicating that most transportation equipment and waste workers are not safely protected. The results also showed that 92.8% of SMW (15,736.4 ton) from all 12 HCFs were inappropriately disposed of through uncontrolled land disposal and incineration. If pharmaceutical wastes and discarded medical plastics (29.5% of SMW) can be separated and treated properly, the treatment costs can be reduced and resource savings can be achieved. Raising awareness of healthcare workers and general public about potential health effects arising from improper SMW management, sufficient financial and human resources for the treatment facilities (especially incinerators), and effective regulations and guidelines for transportation and treatment of SWM are some of the major tasks for safe and sustainable medical waste management in Burundi.

물은 지구상의 생물들이 살아가는데 매우 중요한 역할을 담당한다. 심각한 물 부족 현상이 가난한 지역에 사는 사람들 특히 전세계에서 가장 가난한 아프리카의 시골지역에서 사는 사람들에게 더 큰 문제라는 것을 주목할 필요가 있다. 브룬디는 바로 그런 위험 군에 속하는 나라이다. 본 연구는 아프리카 브룬디의 Kibira 국립공원 인근 7개 지역의 현재와 미래의 물 수요를 예측하였다. 잠재적인 물 수요 군을 일반가정, 가축, 농업부문 및 산업부문으로 나누어 물 수요를 예측하였는데, 이들 지역의 물 수요는 지속적으로 증가할 것으로 예측되었다. 농업생산에 필요한 물의 양은 2020년에는 연간 $288,779,060m^3$, 2050년에는 연간 $306,018,348m^3$로 증가하면서, Kibira 국립공원 인근 지역의 경우 농업부분에서 물 수요가 가장 큰 비중을 차지할 것으로 보인다. 하지만 차 재배가 주 산업인 Muruta와 Bukeye의 경우 2050년 차 산업과 관련된 물 수요가 가장 많은 것으로 나타났다. 따라서 이용 가능한 수자원의 양이 Kibira국립공원 주변 지역의 발전에 가장 큰 영향을 미치는 변수가 될 것으로 보인다. 현재의 수자원 규모는 이들 7개 지역의 미래 물 수요를 충족할 수 없는 것으로 판단되며, 수자원 확보를 위한 필요한 대책을 강구하여야 한다.
