The development of food estates, including peatland ecosystems, is expected to support food security in all regions equally. Technically, the widespread clearing of peatlands for cultivating a specific food crop has multiple environmental effects. The need for more attention to non-technical aspects related to the socioeconomic life of the surrounding community is also an obstacle to the sustainability of the food estate program. In support of food security and sovereignty, this study aimed to develop an implementation framework for sustainably utilizing peat ecosystems as arable land-producing food commodities. A systematic literature review in accordance with the PRISMA guidelines and field observations were used to develop ecosystem concepts by focusing on maintaining an ecosystem’s social, economic, and ecological aspects. This paper describes the history of peat ecosystem utilization, evaluates previous errors in peatland clearing for food, and analyzes the data using the perspective of peat hydrological unit to better understand the livelihood preferences of existing communities. The previous literature’s key findings served as the guidelines for constructing the implementation framework. First, this method identifies people’s natural resource-based livelihoods and describes peatland ecosystems. Second, it evaluates the long-term viability of livelihoods and identifies improvement levers. Finally, it facilitates increasing the scale of food commodities produced from sustainable livelihoods to meet market demand while maintaining ecosystem resilience.

The river water is one of the water resources that important in managing environmental sustainability, increasing economic growth, and realizing the social welfare of communities. This study aims to assess and analyze water quality of the Cimanuk river. The analyze of water quality in the Cimanuk river based on the Regulation of Governor of West Java (GWJ) Class 1, United Kingdom Technical Advisory Group (UKTAG), United States Environmental Protection Agency (USEPA), Ministry of Environmental Government Japan (MOEG), and Departement of Environmental Malaysia (DOE). Nemerow's pollution index (NPI) method used to assess the water in the Cimanuk river from the years 2013 to 2018. River water sampling stations of the Cimanuk river are Boyongbong, Sukaregang, Tomo, and Jatibarang. Base on seven physicochemical parameters, this research found that the Cimanuk river is not meet the water quality standards with the value of TSS (81.57132.69 mg/L), BOD (8.416.53 mg/L), COD (33.9226.51 mg/L), DO (5.541.67 mg/L), and Ammonia (0.210.31 mg/L). The degradation of river water quality in the Cimanuk river indicated by increasing NPI value. NPI value of the Cimanuk river ranging from 1.04 to 7.51. The water quality status of the Cimanuk river has been changing from slightly to moderately polluted. Nowadays, water from the Cimanuk river not suitable to be used as a drinking water source. However, it is still feasible to irrigate agricultural land and plantations.
