Community forestry has several impacts on the environment, both physical and social economics. This study aims to determine the environmental impacts of private forest activities in Central Lombok, especially on runoff and soil erosion. The hydrological modelling approach operating Soil and Water Analysis Tools (SWAT) was used to describe the hydrological response such as runoff and soil erosion that occurs as the impacts of private forests. The results revealed that runoff and soil erosion observed in 2008-2014 had the same trend, with a polynomial pattern that increases at the beginning of the measurement and drops at the end. It means that the longer the age of the private forest, the higher runoff and soil erosion will be reduced and the better the quality of the environment. Thus, intensive private forests need to be development to improve environmental quality.

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.

The Dodokan watershed is one of the priority watersheds on Lombok Island, which is a mainstay for providing water for the community but has a high vulnerability to drought. This condition causes disruption to the fulfillment of water needs, so it needs to be anticipated early with mitigation actions. Understanding the trend of drought is needed as a basis for developing mitigation measures, especially related to land use in the watershed. This study aims to analyze the hydro-meteorological drought trend that occurred from 2009 to 2020 and to find out the role of land use improvement in mitigating drought, which is predicted in the next 10 years. The Thornthwaite–Mather method was used for drought analysis, and its predictions for the next 10 years were determined by using trend analysis. Land use simulation using a spatial analysis was carried out as an effort to prepare for drought mitigation actions. The results show that the drought in the Dodokan Watershed has increased in the period between 2009–2020 and is predicted to continue to increase. Land use improvement by restoring the forest is a more appropriate mitigation method to overcome the drought than rearranging the agricultural land on slopes above 25%. The simulation results have succeeded in increasing the water surplus and reducing the water deficit in 2030 so that it can be used for drought mitigation in the Dodokan watershed.

Lombok Tengah Regency has community forest areas that have the potential to be developed. Current conditions show that many community forests in Lombok Tengah have been developed on marginal land and generally have not implemented intensive land management practices. Thus, land productivity has not been achieved optimally. Improving the quality of marginal land requires intensive land management practices to achieve a balance of ecological, social, and economic functions. The agroforestry pattern is an effort that can be implemented to increase the land productivity of community forests in Lombok Tengah. Agroforestry is a land management system that has great potential to be developed in community forests because it can improve ecological, social, and economic functions. However, not all farmers know the appropriate pattern to increase the productivity of their land. The study aims to determine appropriate land management patterns to be developed in community forests in Lombok Tengah. The method is a focus group discussion (FGD) with 40 farmers in Emboan, Mangkung Village, Lombok Tengah Regency. The study results showed that 78% of farmers in Emboan choose an agroforestry pattern with medicinal plants, especially rhizome types. In comparison, 22% of farmers choose to plant multi-purpose tree species (MPTS) and food crops. Ginger/ jahe ( Zingiber officinale ), galangal/ lengkuas ( Alpinia galanga ), and lemongrass/ serai ( Cymbopogon citratus ) are the most suitable medicinal plants based on biophysical and socio-economic conditions to be developed on community forest in Emboan, Mangkung Village, Lombok Tengah Regency.

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.

Indonesian watershed management continues to struggle with various problems caused by natural disasters, particularly hydrometeorological disasters, which are worsened by the effects of climate change. Coordinating and synchronizing the interest of many parties in watershed management with various scenarios of natural conditions is a big challenge in the creation of a healthy and productive watershed. Multiple initiatives have been undertaken, from establishing rules and policies to implementing them and assessing the effects, leading to various lessons being learned for better management. This article presents a study on watershed management in Indonesia and recommends alternative improvements toward healthy and productive watershed management. A combination of a descriptive qualitative analysis of the authors’ experience in various research activities and a critical analysis is used to examine existing conditions and to formulate recommendations for better sustainable management toward a healthy and productive watershed. Most Indonesian watersheds are susceptible to degradation due to numerous threats. The challenges in Indonesian watershed management, including land degradation and climate-induced disasters, lack of synchronization and coordination, limited resources, and anthropogenic factors, have led to decreased watershed health and productivity and hindered effective management. Integrated management, especially at the micro-watershed level, addresses these challenges. Successful integrated watershed management requires community involvement, appropriate management action for specific locations, technological support, regulatory alignment, and stakeholder collaboration to ensure a healthy, productive, and sustainable watershed for present and future generations.

Under the more current paradigm of protected area management, which takes a more integrated approach to conservation and development opportunities, residents are now seen as co-managers of protected areas. Through the Social Representation Theory, Rational Choice Theory, and Social Identity Theory, this study aims to identify the economic, socio-cultural, and environmental impacts of ecotourism perceived by the residents and their priorities/preferences in Mount Rinjani National Park (MNRP). This study employed the qualitative method (phase 1) and the quantitative method (phase 2). Phase 1 collected primary data through focus group discussion (FGD). The FGD was conducted with 7 participants who were chosen using judgment sampling. Data in the FGD were transcribed and analyzed with content analysis. Results of the analysis in phase 1 were utilized as the basis for analysis in phase 2. Phase 2 collected the data from a survey. Due to the homogeneity of the population, 30 respondents were chosen as the sample using purposive sampling. Data of the survey were analyzed with simple additive weighting. The results showed that the highest preference of the residents was economic impacts, followed by the social-cultural and environmental impacts. From the perspective of Social Representation Theory, it can explain how different people understand and respond to social issues in a community. From the perspective of Rational Choice Theory and Social Identity Theory, although economic impacts rank first, social interest comes first instead of individual interest. Finally, the results of this study can be used as a guide for both the national government (MNRP) and local government (the Culture and Tourism Board) regard to how residents behave towards ecotourism development.
