This paper provides an overview of the implementation and obstacles of watershed management, and the alternative solutions based on a synoptic review of related studies and experiences across Indonesia. The review found that problems in the institutional aspect were hierarchical confusion, discrepancy, and asynchrony among regulations, and weak (participation, synchronization, and coordination) among watershed management stakeholders. The weaknesses in the planning stage are integration among sectors, a lack of community participation, and limited readiness to integrate watershed planning into regional planning. Stakeholders’ involvement is also a critical factor in successful implementation of degraded watershed rehabilitation, including in peatland and mangrove areas. Failure should be minimized by providing adequate information on degraded watershed characteristics, appropriate species choices, and effective mechanical construction for soil and water conservation. Community participation as the main factor in driving watershed management should be achieved by strengthening public awareness of the importance of a sustainable watershed and providing access for the community to be involved in each stage of watershed management. Another problem is data gaps which are essential to address from the planning to evaluation stages. The gaps can be bridged by using remotely sensed data and by applying hydrological-based simulation models. Simplified criteria for watershed assessment may also be required, depending on site-specific issues and the watershed scale.
Dominated by mountainous topography, high rainfall, and erosion-sensitive soil types, and with the majority of its population living in rural areas as farmers, most of Indonesia’s watersheds are highly vulnerable to erosion. In 1984, the Government of Indonesia established 22 priority watersheds to be handled, which marked the start of formal soil and water conservation activities. Although it has not fully succeeded in improving watershed conditions from all aspects, something which is indicated by fluctuations in the area of degraded land, over the past 40 years the Indonesian government has systematically implemented various soil and water conservation techniques in various areas with the support of policies, laws and regulations, and research and development. These systematic efforts have shown positive results, with a 40% reduction in the area of degraded land over the last 15 years from 2004–2018. This paper reviews policy, implementation, and research and development of soil and water conservation activities in Indonesia over the last 40 years from the 1980s to 2020 and explores the dynamics of the activities.
One causes of the clean water scarcity problem in Indonesia is the poor quality of the available water. Many of the stream flows have been appallingly polluted and could not be consumed properly. Some of the stream flows from forest areas also show indication that they have been contaminated by pollutant substances. River water quality is closely related to the types of land uses. Research conducted in pine forest area in Gombong was aimed at determining the effects of land uses on river water quality. Thirteen stations along the Kemit river were selected as observation points of water samples. Based on the observation, the results indicated that in general, river water quality within pine forest area in Gombong had good quality and can be used for washing and bathing, whereas, lower stream had poor quality. The quality of river water decreased along with the increasing numbers and types of land uses within catchment area. The poor quality of the water mainly was affected by land uses, such as settlement, rice field, and agricultural land. Deposition of those pollutants from human activities, such as pesticides and domestic wastes within the river may have negative impacts to the environment. Therefore, to sustain and maintain the water quality of the river, comprehensive efforts on reducing pollutants from the catchment area are urgently required. The efforts include reforestation around the settlements, improvement of recharge area of agricultural wastes and control of the domestic waste.
Indonesia is an archipelago with significant variations in natural resources, infrastructure, socioeconomic, culture, human resource capacity, accessibility, and access to financial and technical assistance. In this situation, integrated and unique efforts are needed to manage natural resources and build synergy between their protection and utilization to achieve water, energy, and food (WEF) security in accordance with the SDG targets. This paper analyzes the implementations of the WEF nexus in rural Indonesia by examining existing legal frameworks and other related policies, journals, textbooks, and publications. We explore factors influencing the success and failure of the implementation of the WEF nexus approaches from technical, socioeconomic, cultural, political, and institutional perspectives of the rural development framework.
Climate change is a major challenge for Indonesia due to its impact on food, water, energy sustainability, and environmental health. Almost all Indonesian regions are exposed to floods, landslides, soil erosion, drought, and heavy rains. In response to these challenges, the Government of Indonesia has determined integrated watershed management (IWM) to be one of the key programs to reduce greenhouse gas (GHG) emissions, as stated in the updated Indonesian nationally determined contribution (NDC). This paper intends to review Indonesia′s efforts in mitigating and adapting to climate change through an IWM approach, and its attempts to realize a decent life and environment for all communities. Improvement of the IWM can be conducted by strengthening the synergy between the responsible institutions for watershed management and the responsible institutions for handling mitigation and adaptation of climate change impacts. In addition, it is important to prioritize coordination, participation, and collaboration not only at the national government level but also at the international level, since numerous problems may exist in the transboundary between countries, and finding solutions should involve planning, implementation, monitoring, and evaluation. Implementing the micro watershed model (MWM), supported by culture, local wisdom, and traditional knowledge in communities, can be used to improve the current IWM.
