INPROSULA

This is a reforestation project in Wonoharjo Village, Central Java, situated within a roughly 400-hectare community forest landscape. The project's ambition is substantial: transform a total of 100 hectares of degraded land into a productive, climate-resilient agroforestry ecosystem.

The initiative is driven by a partnership between the legally mandated local farmer group, Tree Planting Partner INPROSULA, and TREEO, which leads carbon project development and digital MRV. Together, the three combine ecological restoration, livelihood development, and rigorous digital monitoring into a single, measurable model for community impact.

The farmer group holds a Social Forestry Forest Utilization Permit valid for 35 years, from 2017 to 2052, giving the project the long-term legal and tenure foundation needed for a multi-decade agroforestry commitment.

Field surveys and ground-truthing confirmed that the selected land is severely degraded. After previous harvesting, the state company responsible for the land never replanted it, leaving it largely bare before it was gradually converted to short-term corn cropping, a land use pattern that offered farmers income, but little long-term ecological or economic security.

This history is exactly what gives the restoration effort its clear additionality: by transforming bare, unmanaged ground into a structured, productive ecosystem, the project generates climate and livelihood outcomes that would not have emerged under a business-as-usual scenario.

The initial project was designed to include the planting and maintenance of 85,781 seedlings comprising the following seven different tree species and their respective shares:

• Paraserianthes falcataria (Sengon): 50%
• Anthocephalus cadamba (Jabon): 30%
• Tectona grandis (Teak): 10%
• Persea americana (Avocado): 10%
• Parkia speciosa (Stinky bean)
• Mangifera indica (Mango)
• Manilkara zapota (Sapota): <1% combined

The selected species are a mix of fast-growing wood and fruit trees, supporting long-term ecological restoration, carbon accumulation, and potential community livelihood benefits.

These species were chosen through an intense socialization process based on farmer preferences, carbon performance, and biodiversity. This selection creates direct synergies with local livelihoods, particularly by supporting farmers in transitioning from short-term cropping patterns toward long-term agroforestry management. Additionally it provides opportunities to utilize organic waste for biochar production.

Through single-tree monitoring app solutions, smallholder farmers across Indonesia are empowered to digitize their forests. Utilizing smartphone cameras, our dMRV (digital Measurement, Reporting, and Verification) system analyzes tree trunk diameter, canopy coverage, and species growth over time. Each tree receives a unique digital identity, linking precise carbon sequestration calculations with trusted global buyers.

Deploying digital monitoring tools on the ground required specific adaptations to assist users in the field. To reduce inaccurate GPS measurements, a 10 m GPS accuracy threshold was implemented. Additionally, visualizing plot polygons on the app and adding offline map features were necessary steps to help users easily locate their monitored plots in the field.

Successfully completed the initial planting phase with approximately 88,015 seedlings deployed. The project secured an estimated Long Term Average (LTA) of carbon sequestration reaching 16,414 tCO2 over a 30-year duration, under the validation of Carbon Standards International (CSI) and digital monitoring tracking.

Wonoharjo is a project about transition, not just of degraded land into forest, but of farming culture itself, from short-term extraction toward long-term stewardship. By designing species selection, income models, and even monitoring technology around how the community actually works, the project offers a grounded example of what it takes to make social forestry genuinely sustainable, both ecologically and socially.
