Identification of the Environmental Impacts and Management Strategies of Embung Bandungrejo

Abstract

Water reservoirs in the form of artificial lake or embung are needed for water resources conservation and fulfilment of other functions. The development of Embung Bandungrejo is planned not only for conservation but also for irrigation and tourism potential. The construction of environmental conservation facilities has created new problems for the environment otherwise. This study aimed to identify the types and sources of environmental impacts and to analyze the environmental management efforts in Embung Bandungrejo. The method to collect data was carried out through a combination of primary and secondary data gathering. The results of data processing were then analyzed descriptively based on professional judgment. The environmental impacts are estimated to occur during the pre-construction, construction, and operation stages. The pre-construction stage consists of two activities that potentially have environmental impacts, namely planning, survey, and measurement as well as dissemination. The predicted impact of such activities is public perception and attitude. The construction stage consists of five activities with potential environmental impacts. The impacts of worker recruitment include the creation of employment and business opportunities and the emergence of social envy. The basecamp operation affects public perception and attitude as well as degraded environmental sanitation. The impacts of equipment and material mobility are increased dust deposits and vehicle exhaust gases, damaged roads, and public concern. The earthwork leads to land-use change and threatened wildlife habitat. The impact of construction activities is potential occupational diseases and accidents. The operation stage consists of two activities with the potential to cause environmental impacts. The embung utilization decreases environmental sanitation, increases the population of aquatic biota and flora, improves the standard of living for farmers and the community, as well as causes conflicts of irrigation water use and tourism management. The impact of embung maintenance is the good condition and well-maintained complementary facilities the environmental management strategies can be carried out on each type of projected impacts based on the form, location, and period of the management efforts.
