Sustainability Assessment of the Upstream Bengawan Solo Watershed in Wonogiri Regency, Central Java Province, Indonesia

Abstract

The sustainability of watershed management is a key issue that must be considered to ensure the continuation of watershed services such as agriculture, food, and energy. This concern has also been raised in Presidential Regulation No. 2/2015 and No. 18/2020 regarding the National Medium-Term Development plans for the periods of 2015–2019 and 2020–2024, which mandate the restoration of priority watersheds, one of which is the Upstream Bengawan Solo Watershed. The purpose of this study is to fill this knowledge gap by measuring the sustainability of this watershed from a time dynamics perspective. However, several factors can influence the achievement of sustainable development. This paper assesses the sustainability of the watershed over several periods using MDS (Multidimensional Scaling) analysis with the assistance of modified Rapfish (Rapid Appraisal for Fisheries) software (2013 version). The information used in this case study was collected from 20 districts in relation to social, economic, and environmental dimensions. Our result shows that the average index of the social dimension increases from 2007 to 2019 and 2021, while the economic dimension tends to fluctuate. A decrease occurs from 2007 to 2019, and then increases from 2019 to 2021. This differs significantly from the environmental dimension, which decreases from 2007 to 2019 to 2021. The sustainability scores were then compared across regions. The lessons learned in this study can be incorporated into regional policies and actions to overcome challenges in the implementation phase.
