“…With this involvement, it is expected that the status of Lake Limboto will be sustainable. The community participation in the maintenance of the lake is a key to ensure that benefits provided by the lake can be enjoyed sustainably by current and future generations (Zhong et al, 2022). Thus, active community participation in sustainable lake management is a determining factor for the preservation of the lake and ensuring that the lake resources will continue to provide sustainable benefits for the entire community (Melo and Samatowa, 2023).…”

Lake Limboto, situated in Gorontalo, Indonesia, confronts severe threats jeopardizing its sustainability. Widespread deforestation in the watershed area has led to excessive sedimentation within the lake, consequently diminishing its water storage capacity and compromising its flood control function. This degradation has manifested itself in downstream droughts during the dry season and flooding during the rainy season. Historical data reveals a stark reduction in Lake Limboto’s size, plummeting from approximately 3,644.5 ha in 1991 to around 2,693.9 ha in 2017. This study aims to provide comprehensive examination of the interplay between the socioeconomic status of the local community and their understanding of the lake ecosystem. Furthermore, it delves into how these factors produce synergies that shape and impact community involvement in sustainable lake management initiatives. Hypothesis testing yielded significant results, affirming the existence of a positive correlation between socioeconomic status, knowledge of the lake ecosystem, and active community participation in sustainable lake management efforts. The findings underscore the critical importance of socioeconomic factors that need to be considered when designing strategies for the preservation and sustainable management of Lake Limboto. Integrating the community into conservation initiatives is necessary, given their intrinsic relationship with the lake. By acknowledging and leveraging the nexus between socioeconomic status, ecological knowledge, and active participation, stakeholders can formulate more effective and inclusive strategies for safeguarding Lake Limboto’s ecological integrity. This study contributes valuable insights for policymakers, environmentalists, and local communities alike, emphasizing the necessity of collaborative efforts to ensure the long-term resilience and vitality of Lake Limboto.

“…Studies show that around 30% of the total nitrogen (TN) entering the ELB is fertilizer-derived, with fertilizer diffusion being the primary contributor to mineral-N in the basin 12 . Tobacco farming, a key economic activity in the ELB, has seen over 3,500 ha under cultivation since 2021, signi cantly boosting the local economy and aiding farmer income 13 . Therefore, striking a balance between reducing nutrient loss from tobacco elds, ensuring high-quality tobacco production, and supporting farmer income is critical for environmental conservation and the sustainable development of agriculture in the ELB.…”

Efficient nutrient management is imperative to control nutrient losses from farmland in the Erhai Lake Basin (ELB). To address this, a two-year field experiment (2021–2022) was conducted in the northern part of the ELB. The study aimed to quantify the impact of various fertilization treatments on nitrogen (N) and phosphorus (P) losses. The four fertilizer treatments included: no fertilizer (CK), farmer’s fertilizer-purely organic fertilization (FP), chemical fertilizer (CF), and a combination of organic and inorganic fertilizers (OIC). The OIC treatment significantly decreased N losses throughout the entire flue-cured tobacco season compared to the FP treatment, reducing TN runoff losses by 2.68 kg ha− 1 and TP runoff losses by 0.10 kg ha− 1. For leaching losses, the OIC treatment demonstrated a reduction of 21.3% in total N (TN) losses and 17.3% in total P (TP) losses compared to the purely organic fertilization treatments. Regarding yield and economic, the two-year average yield of the OIC treatment was 2573.93 kg ha− 1, a 3.8% increase compared to the FP treatment, accompanied by a significant rise in economic value. Correlation analysis revealed that soil available N and soil water content were key factors significantly influencing TN and TP runoff losses. These findings offer a theoretical foundation for the control of nutrient losses in farmland in the ELB.
