Project Management Unit of Green Growth Strategy Facility (GGSF) has supported Ha Tinh province with a Project "Analysis, assessment and recommendation of solutions to minimize environmental pollution Nghen river water towards Green growth". In this moment, this project is absolutely necessary. The results of these scientific researches, if done well, will be important and input information for directing the sustainable development strategy of the province.

 In recent years, although the achieved economic growth is quite high, Ha Tinh has been facing a lot of serious challenges. First of all, they are the impact of climate change, risk of depletion of natural resources, increase in environmental pollution, lower  development level, production efficiency, consumption, unsatisfactory to requirements for environmental friendliness. Besides, the province has not had enough fund to carry out detailed and reliable surveys or scientific calculations on level of greenhouse gas emissions, environmental pollution. Therefore, the assessment, screening, verification of the information on climate change, greenhouse gas emissions, environmental pollution levels to integrate into the process of the provincial socio-economic development - is considered to be compulsory requirement. With great achievements in economics as indicated above, on the down side of it, pollution is a challenge to the socio-economic development and pollution in Nghen river is one of them. Therefore, Project Management Unit of Green Growth Strategy Facility (GGSF) has supported Ha Tinh province with a Project "Analysis, assessment and recommendation of solutions to minimize environmental pollution Nghen river water towards Green growth". In this moment, this project is absolutely necessary. The results of these scientific researches, if done well, will be important and input information for directing the sustainable development strategy of the province.

 The river water is contaminated by many sources, including the following subjective reasons, such as, untreated wastewater from industrial activities, sand/mineral mining, traditional production villages, agriculture, health, animal husbandry, dosmetic waste water, ...directly discharged into the river; estimatedly, thousands of cubic meters of dosmetic waste water/day-night by about 400 thousand households discharged to the river, containing high organic content, and microorganisms, including pathogenic microorganism which is one of the main sources of pollution to water environment. Coastal and river aquaculture: River caged fish farming in Nghen helped to stablize many family lives, contributing to increase fish production. However, due to river pollution, many households in Nghen have become impecunious and stopped their farming. Caged fish farming itself is one of the main pollution sources too because it causes ecological imbalance, impacting the natural flows of the river and wastes from farming such as chemicals, medicines, fish food in to the river. In addition, there are also other unknown reasons which should be identified through surveys, reviews of scientists.

Therefore, identifying pollution sources, level of water pollution and recommendation of mitigation measures, research and pilots for implementation of green infrastructure, ensuring the water treated by "green"-designed treatment discharged into rivers qualified, thereby improving the quality of Nghen river water. Basing on the reliable data given by surveys, analysis and evaluation of the scientists, to identify the opportunities and challenges. Identification of assessment, analysis will create prerequisites to propose orientations and solutions for sustainable development objectives towards green growth.
