Land degradation due to intensive agricultural practices is a serious issue threatening food security and ecosystem balance. Monoculture farming systems often lead to soil fertility decline, increased erosion, and reduced soil biodiversity. As an alternative, agroforestry has been developed to enhance agricultural productivity without compromising soil health. Agroforestry integrates agricultural crops with trees or other woody plants in a mutually beneficial system. Several studies have shown that agroforestry improves soil organic matter content, retains soil moisture, and reduces erosion and nutrient loss. This study employs a literature review method to analyze the effectiveness of agroforestry in improving soil health and agricultural productivity. Agroforestry has been found to enhance agricultural productivity through crop diversification, efficient land use, and climate change mitigation. Diversification not only strengthens food security but also increases farmers’ income by minimizing crop failure risks and enhancing nutritional value. Additionally, agroforestry optimizes land use by improving yield per unit area and reducing environmental degradation through natural resource conservation. Agroforestry also plays a crucial role in mitigating climate change by increasing ecosystem resilience, sequestering carbon, and reducing extreme weather impacts. However, the adoption of agroforestry faces challenges, including a lack of farmers’ knowledge, limited policy support, and varying environmental conditions. Addressing these barriers through improved education, supportive policies, and sustainable resource management can accelerate agroforestry adoption. With broader implementation and strong policy support, agroforestry can drive agricultural sustainability and enhance community well-being.

The Perintis Lake area in Bone Bolango Regency, Gorontalo Province, faces a growing conflict between tourism investment and environmental conservation. This study aims to analyze the impact of tourism infrastructure development on the lake’s ecosystem, highlight the importance of conservation, and provide strategic recommendations for sustainable tourism development. Using a qualitative-descriptive approach, the research is based on field observations, literature review, and regional policy analysis. Findings show that unregulated investment activities, particularly constructions along the lake's buffer zone, have led to environmental degradation, such as water pollution, habitat loss, and ecological imbalance. Conservation efforts remain fragmented and lack integration into broader development planning. The study recommends the implementation of sustainable spatial planning policies, stricter environmental regulations, and active community involvement. Collaborative governance between local authorities, private investors, and environmental stakeholders is essential to ensure that economic development aligns with ecological preservation. Striking a balance between investment and conservation is key to maintaining Perintis Lake as a resilient ecotourism destination for future generations.

This study aims to analyze the level of attack by Macaca hecki on cultivated plants in Makarti Jaya Village, Pohuwato, Gorontalo. Agriculture is the main source of income for the local community, but the presence of Macaca hecki can threaten agricultural yields. The method used in this research is descriptive qualitative, with data collected through direct observation and interviews with farmers experiencing the attacks. The results indicate that corn (Zea mays) is the most consumed plant by Macaca hecki, followed by cocoa (Theobroma cacao) and several other types of fruit such as bananas and papayas. The high consumption rates of these cultivated plants negatively impact agricultural results, causing significant economic losses for farmers. Therefore, it is important to understand the attack patterns and the factors influencing the behavior of Macaca hecki. This research recommends the need for more effective protection strategies, such as the placement of physical barriers and diversification of plant types. Thus, it is hoped that this study can contribute to the management of conflicts between wildlife and agriculture, as well as enhance the economic sustainability of farming communities.

This study aims to determine the composition and structure of vegetation and estimate the potential for carbon dioxide absorption in the Tangale Nature Reserve Area, Gorontalo Regency. The method used in this study is the determination of sampling locations carried out by purposive sampling, making multilevel plots, analyzing vegetation structure, and estimating tree biomass is done non-destructively based on measuring the height and diameter of trees at breast height (DBH), while for lower plants it is done destructively and litter is taken all in the plot area to be weighed wet and dry weight and then estimating biomass, C reserves, and CO2 uptake. The results showed that the vegetation composition consisted of 18 species dominated by the Magnoliopsida class. The highest Important Value Index is found at each observation station. Calculation of biomass value, C reserves, and CO2 uptake at each observation station showed varying results because they were influenced by vegetation type, vegetation density, vegetation composition and structure, and environmental factors. The total value of CO2 uptake by vegetation in the Tangale Nature Reserve Area is 5,304.393 tons of CO2/ha. This research provides a better understanding of carbon sequestration potential in conservation areas to support environmental conservation and climate change mitigation efforts.
