Socio-Eco-efficiency Indictors Effect on Water Consumption and Recycling Efficiency in Kombolecha, Ethiopia

Abstract

Ethiopia is amongst agrarian economy but drought affected and rainfall dependent country in eastern Africa. Water consumption growth and green environmental problems were increasing parallel to factories production growth and population density rise in Kombolecha city. Consumers were used water resources for different purposes to attain their optimal social, economic and environmental aspects. However, consumer’s economic, social, and environmental indicators were disintegrated in the course of water consumption and recycling process. This study intended to determine the effect of socio-coefficient indicators on water consumption and recycling efficiency in Kombolecha. In doing so, this study employed instrumental variable model and two stages least square estimation that could be integrated the consumer’s social, economic and environmental indicators and built a socio-eco efficiency framework, which maintain water consumption and recycling efficiency in drought affected cities. In addition to this, propensity score matching estimation was used to evaluate the impacts of consumer’s poverty and consumption behaviours effect on water consumption and recycling efficiency. Accordingly, this study investigated that consumer’s water consumption behaviours were found different and varied across their production and consumption purposes in Kombolecha. For instance, factories were used different quantities of water along with their type of production. It was also computed that consumer’s social, economic and environmental aspects were associated with their water consumption and recycling processes. However, household’s consumption behavior and poverty level was negatively associated and affected the water consumption and recycling efficiency at the 5 percent significance level. In this study, nonetheless, rather than each separate indicator, the socio- eco efficiency framework, which consisted the three key indicators, were positively and statistically significant and influenced consumer’s water consumption and recycling efficiency in meeting green environment resilience. This study, thus, recommends that environment protection offices should be tactically integrated consumer’s social, economic and environmental indicators to build socio- eco efficiency that recover the green environment Kombolecha and at large in Ethiopia.
