Ecosystem Service Reason to Save Wetlands: A Case of Geray Wetland, North Western Ethiopia
Abstract
Efforts to conserve wetland ecosystems depend on the recognition of ecosystem services they provide. Hence, the study was conducted to analyze the ecosystem services of the Geray wetland and the driving force of its degradation. Structured questionnaires, personal interviews, focused group discussions, and field observations were used in data collection. Questionnaires were administered to 114 respondents obtained through random sampling of households. Data were analyzed using descriptive statistics and regression. Descriptive statistics like mean, percentage and frequency distribution were used to analyze quantitative data. The binary logistic regression model was applied to evaluate the impact of household-related independent variables on the dependent variable. Results showed that Geray wetland provides provisioning services (fish, fresh water, fodder and grazing services, firewood, crop, and fruit), regulating services (temperature regulation, water purification, sediment retention and erosion control), cultural services (recreation, tourism, and aesthetic) and supporting services (nursery, habitat, and accumulation of organic matter). Farm expansion, sedimentation, overgrazing, uncontrolled irrigation practices and deforestation of wetland vegetation, which are rooted in rapid population growth, open access to wetland resources, lack of awareness, lack of clear boundaries and weak institutional framework, were the main causes of the wetland degradation. Predictor variables like household size have a negative, and landholding size and age have positive significant impacts on the Geray wetland ecosystem. A high number of respondents were also aware of the measures (planting trees, trace building as a controlling method of erosion and conservation education to the community) to be taken to overcome the problems that face the Geray wetland. Thus, participatory sustainable wetland management is recommended to obtain more benefits from the wetland and minimize its destruction
