1. Objectives
By the end of this module, participants will be able to:
- Understand the economic feasibility of agarwood plantations.
- Identify and quantify capital and operational costs.
- Estimate revenues from resin, timber, and intercropping crops.
- Calculate key financial metrics: ROI, NPV, and payback period.

2. Key Concepts in Cost-Benefit Analysis
- Capital Costs (Initial Investment)
- Land acquisition or lease
- Nursery setup (seed trays, pots, shading, irrigation)
- Seed/seedling purchase
- Planting and soil preparation
- Irrigation and fencing
- Tools and equipment
- Operational Costs (Recurring)
- Labor: planting, maintenance, pruning, inoculation
- Fertilizers and soil amendments
- Pest and disease management
- Irrigation and water management
- Monitoring, recordkeeping, and ESG compliance
- Revenue Streams
- Resin/oil production (primary product)
- Intercropping crops (vegetables, fruit trees, legumes)
- Timber (long-term revenue)
- Carbon credits or ecosystem service payments (optional)
- Time Horizon
- Typical resin induction period: 5–8 years
- Timber revenue: 15–25 years
- Intercropping: annual or seasonal
3. Sample Cost-Benefit Structure
| Category | Cost/Revenue | Notes |
|---|---|---|
| Land preparation | PHP 50,000/ha | Clearing, plowing, soil amendment |
| Seedlings | PHP 500,000/ha | 1,000–1,100 seedlings at PHP 450–500 each |
| Planting labor | PHP 20,000/ha | Initial planting |
| Fertilizer & soil amendment | PHP 30,000/yr | Organic compost, NPK, biochar |
| Pest & disease management | PHP 15,000/yr | Biocontrol, organic sprays |
| Irrigation & water | PHP 10,000/yr | Drip or manual irrigation |
| Pruning & maintenance | PHP 15,000/yr | 2–3 events per year |
| Resin induction inoculants | PHP 50,000–75,000/ha | Dual-action microbial or chemical blends |
| Harvesting | PHP 20,000/ha | Collection & processing |
| Revenue from resin | PHP 500,000–2,000,000/ha | Depending on quality and yield |
| Revenue from intercropping | PHP 50,000–150,000/yr | Vegetables, fruit, legumes |
| Timber revenue (future) | PHP 300,000–500,000/ha | After 15–20 years |
| Carbon credits | PHP 0–100,000/ha | Optional, based on certification |
Note: Figures are illustrative; actual costs depend on location, labor rates, tree density, and inoculation techniques.
4. Financial Metrics
- Net Present Value (NPV)
[
NPV = \sum \frac{R_t – C_t}{(1+i)^t}
]- (R_t): revenue at year t
- (C_t): cost at year t
- (i): discount rate
- Internal Rate of Return (IRR)
- The discount rate where NPV = 0.
- Return on Investment (ROI)
[
ROI (%) = \frac{\text{Total Net Profit}}{\text{Total Investment}} \times 100
] - Payback Period
- Time needed for cumulative net profit to equal initial investment.
5. Factors Affecting Cost-Benefit Outcomes
| Factor | Impact on CBA |
|---|---|
| Tree survival & growth | Higher survival = better ROI |
| Resin yield & quality | Premium-quality resin dramatically increases revenue |
| Labor costs | Local wage rates and efficiency influence operational cost |
| Inoculation method | Biotechnological methods may increase initial costs but shorten resin induction time |
| Intercropping & agroforestry | Generates early cash flow to offset operational costs |
| Market price fluctuations | Global demand for agarwood oil and chips affects revenue |
| ESG & sustainability certification | May provide premium market access or carbon credits |
6. Sample ROI Timeline
| Year | Costs (PHP/ha) | Revenue (PHP/ha) | Cumulative Profit |
|---|---|---|---|
| 0 | 200,000 | 0 | -200,000 |
| 1 | 50,000 | 50,000 (intercrop) | -200,000 + 0 = -150,000 |
| 2 | 50,000 | 50,000 | -150,000 + 0 = -100,000 |
| 3 | 50,000 | 100,000 | 0 |
| 4 | 50,000 | 100,000 | +50,000 |
| 5 | 50,000 | 500,000 (resin) | +500,000 |
| 6–8 | 50,000/yr | 500,000–700,000 | Increasing net profit |
Observation: Early intercropping reduces financial risk while waiting for main resin revenue.
7. Risk Considerations
- Pest & disease outbreaks reduce yield.
- Climatic extremes (drought, storms) affect survival.
- Market volatility for agarwood chips and oil.
- Policy and regulatory compliance costs (CITES, DENR-BMB).
Mitigation: Integrated pest management, climate-smart farming, insurance, and community engagement.
8. Decision-Making Using CBA
- Compare alternative plantation designs:
- Monoculture vs. intercropped systems
- Different inoculation or resin induction methods
- Assess feasibility of ESG certification or carbon credit participation.
- Determine optimal planting density and tree spacing for maximum financial and ecological return.
- Identify break-even point for investors and smallholder farmers.
9. Summary Best Practices
- Combine resin, timber, and intercrop revenue streams for balanced cash flow.
- Use biotechnological inoculation to reduce resin induction period and increase high-quality yield.
- Monitor tree growth, health, and environmental conditions to maximize ROI.
- Include climate-smart and biodiversity-friendly practices to attract ESG-conscious investors.
- Keep detailed cost and revenue records for future planning and scalability.
