🔹 3. Intervention / Innovation (Strategy – Method – Tools used)
Innovation or working methods | Development and transfer of "green technology" (12 technologies)
|
Traceability and establishing criteria | |
Ecosystem Building | |
Strengths | Proactive management:Not just "avoiding" but using technologies to "fix" (e.g. reduce residue) and "prevent" (e.g. protect against external chemicals) Turn waste into resources:Convert longan branches (waste) into biochar (soil improver/chemical reduction material) Build a defense system:Prevent cross-contamination from surrounding areas (through soil, water and air) Build credibility:Use technology (Test kit, drone, LCMSMS) to monitor and create product selection criteria. Reduce costs:Develop criteria for using (low-cost) test kits to create PGS standards that farmers can access. End-to-End:Connecting "academics" (technology developers), "farmers" (users), and "businesses" (buyers/supporters). |
Draw a miniature model (Impact Model Diagram) : OPTIONAL** Problem → Intervention → Change → Value
Problem (agriculture relies on chemicals/poor health/high costs) → Intervention (green technology + test kit + network) → Change (reduce chemical costs/reduce residues in soil and water/better health) → Value (SROI 1.39 / sustainable agriculture / stable purchasing market)
💡 Key points of emphasis:It shows that this project “changes the way of thinking or doing”, causing changes from the original.
🔹 4. Impact Pathway / Theory of Change (Path of Change)
Use a linkage modelInput → Activity → Output → Outcome → Impact

Output | The resulting product |
|
Outcome | Qualitative change | Economic:Farmers reduce the cost of using chemicals, reduce the cost of removing longan branches and reduce the cost of chemical inspections. Social aspect:Create a network of farmers and better relationships in the community. In terms of quality of life:Farmers have better health and less illness. |
Impact | Systemic/Sustainable Change | Environmental aspectsReduce the use of chemicals in agricultural areas (reduce soil and water contamination) In terms of innovationNew green technologies and verification criteria are being implemented. System sideA collaborative "ecosystem" (farmers-academics-private sector) has emerged for the transition to chemical-free agriculture. |
🌱 Key points of emphasis:Helps to see the actual “Impact Pathway” that the project is creating.
🔹 5. Evidence & Indicators (Evidence and outcome indicators)
Specify quantitative and qualitative results, such as:
Quantitative | Total result value (Y0+Y1): 23,676,925.51 baht economy:15,035,029.83 baht (63.50%) such as reducing chemical costs by 7.59 million baht, reducing longan branch removal costs by 2.65 million baht, reducing inspection costs for Thai Thonburi Co., Ltd. by 2.04 million baht. environment:5,989,483.52 baht (25.30%) such as the value of reducing chemicals in soil 4.53 million baht, reducing chemicals in water 1.35 million baht. innovation:1,600,634.91 baht (6.76%) such as Protocol, course society:757,499.53 baht (3.20%) such as networking Quality of life:294,277.72 baht (1.24%) such as reducing medical expenses |
Qualitative |

SROI / Economic Valuation | SROI Ratio: 1.39 (Investment of 1 baht creates social, economic and environmental results of 1.39 baht) Sensitivity Analysis:If organic longan yields are low (in 2027) and farmers stop using the technology, SROI will decrease to1.28 |
📊 Key points of emphasis:To show that results are “tangible” and reflect value, not just output.
🔹 6. SV Key Lessons Learned (Key Lessons / Success Factors)
Factors contributing to project success | 1. Partnership (Comprehensive Cooperation):The collaboration of academics (technology development), the private sector (funding/Test kit/purchasing) and farmers (implementation) has led to systemic change. 2. Technology (Appropriate technology):Having 12 clear green technologies gives farmers the tools to “prevent” and “solve” chemical problems. 3. Traceability (Auditability):The use of test kits and lab testing helps raise awareness among farmers and build standards/confidence among buyers. |
Obstacles and lessons learned from operations | 1. The risk that farmers may decide to discontinue using green technologies 2. Process limitations:The amount of biochar produced may not be sufficient for use in the field. 3. Economic constraints:The returns/productivity are still slow during the adjustment period and the price is still fluctuating according to the market mechanism. 4. Cost constraints:The cost of monitoring and evaluating chemical residues remains high. |
role | Researchers (Change Leaders):It is the core of technology development, knowledge transfer and network coordination. Model farmers (network leaders):Acting as a group leader, transferring technology to the expansion plots Private Sector (Strategic Supporters):Living Choice Co., Ltd. jointly developed the inspection protocol, and Thai Thanaburi Co., Ltd. created a guarantee for purchasing the produce (Demand). |
🔹 7. Impact Scalability
In summary, how can this process be “extended/expanded” to other areas?
This project has created a "knowledge base" (12 technologies), training curriculum, and testing criteria (Protocol Test kit) that have been tested and proven. This knowledge base is therefore highly replicable and can be transferred and expanded to other farmer groups or other crops that wish to transition to chemical-free agriculture.
Project wants to expand cooperation. What to develop? Invite Impact Partnership.
Market side:We need partners who can guarantee prices (price guarantee) or create a purchasing market (have a purchasing market) for long-term chemical-free produce for farmers.
Policy/Certification:Cooperation is needed to promote standards and product certification (set and create standards and product certification) that arise from this process to build market confidence.
🧩 Key points of emphasis:Let's see the "opportunity to further apply this model" and join hands.— Help the association select cases with high potential for public dissemination.
🔹 8. SV Inspiration (Reflection of social values)
“What value did this project create for people and society?”
Reflected from the perspective of beneficiaries (stakeholder voice)
The most important value this project creates is that it unlocks farmers from their reliance on chemicals, not by forcing them to stop, but by providing them with the tools (green technology) and ensuring they do so (monitoring). This project proves that the shift to chemical-free farming doesn't just benefit the environment (cleaner soil and water) or consumers, but also directly impacts farmers themselves.
Quality of life value:Farmers have significantly improved health, with fewer illnesses and hospitalizations (valued at 294,277.72 baht).
Community economic value:Turning "waste" (longan branches) into "resources" (biochar) can truly help reduce disposal costs and reduce the cost of using chemicals.
Relationship Value:Strengthened collaboration and networks between farmers, researchers, and local scholars
