Agriculture Feasibility Section 5. Conservative estimate. Article 6 bilateral deals and high-integrity markets price tropical agroforestry at $30-50/tCO2e as of 2025.
500 ha pilot carbon revenue: ~$48,750/year
ESTIMATED$48,750/yr
Derived: 500 ha × 6.5 tCO2e/ha/yr (mid IPCC range) × $15/tCO2e (upper conservative market rate).
Mathematical derivation from IPCC AR6 range (3.5-9.8 tCO2e) mid-point (6.5) and World Bank price upper conservative ($15/t). Actual credits require Verra VCS verification.
Carbon revenue is additive to agriculture produce revenue. Cannot be double-counted with Verra REDD+ if overlapping land parcels. Verified by third-party auditor before credit issuance.
65,000 ha full programme carbon revenue: ~$6.3M/year
ESTIMATED$6.3M/yr
Derived: 65,000 ha × 6.5 tCO2e/ha/yr × $15/tCO2e.
Mathematical extrapolation of pilot calculation to full programme scale. Assumes consistent agroforestry management and successful VCS certification of all parcels.
Full programme carbon revenue represents a material non-correlated income stream for the CaribVista Jamaica Land Trust.
Agroforestry premium revenue Year 5 (500 ha): $490K
ESTIMATED$490K (Yr 5, 500 ha)
Derived from: shade-grown premium ($443-1,485/ha) × 500 ha at mid maturity. Conservative end of CARDI range ($980/ha) × 500 ha = $490K.
CARDI range represents 3-8 year mature system. Year 5 projection uses conservative lower-to-mid range ($980/ha). Does not include carbon credit value (counted separately).
Agriculture Feasibility revenue timeline Year 5 agroforestry column. Premium represents: (a) shade-grown quality uplift, (b) bird pest control savings, (c) organic certification premium.
Organic certification adds 30-60% to final sale price
PUBLISHED30-60% premium
Rodale Institute: Organic Certification Price Premium Analysis (2023). USDA Organic Market Summary 2023.
https://rodaleinstitute.org/blog/organic-certification-costs-a-small-investme...USDA data shows organic produce commands 30-60% premium at wholesale. Caribbean agroforestry typically eligible for organic certification by Year 3 (transition period). Applies to coffee, cocoa, pepper, ginger.
Organic certification requires 3-year transition period with no prohibited substances. CARDI provides certification support for Caribbean smallholders.
FINANCIAL MODEL INTEGRITY NOTE
The base financial model (10-year IRR 20.1%, pilot breakeven mid-Year 3) was calculated using agricultural produce revenue only. Carbon credits and agroforestry premiums are presented as additive upside scenarios, not base case assumptions. This conservative approach ensures the project is viable purely on food production economics. Carbon and agroforestry premium revenues improve the IRR to approximately 23-26% depending on carbon price realisation.
PART H
NCD Health Crisis: Agriculture as Public Health Intervention
Source verification for all NCD health data linked to Jamaica's food import dependency. This section establishes the evidence base for CaribVista's SDG 2 (Zero Hunger) and SDG 3 (Good Health) claims.
The thesis: Jamaica's NCD crisis is structurally linked to 80% food import dependency. When 80% of food is imported, a country cannot control population diet quality. Ultra-processed food imports dominate the affordable food supply. Every hectare of idle grassland activated reduces import dependency and increases availability of fresh, nutritious local food. This is not a soft co-benefit — it is a quantifiable public health and GDP intervention.
80% of Jamaica's deaths are from NCDs

Obesity is a primary driver of diabetes, cardiovascular disease, and cancer risk. 61.1% of adults overweight means most of the adult population is at elevated NCD risk.

Fresh local food displaces ultra-processed imports (causal mechanism)
PUBLISHEDDisplacement mechanism
PAHO Ultra-Processed Food Sales in Latin America and the Caribbean (2021). Global Food Policy Report (IFPRI) 2023 — Caribbean Chapter.
https://www.paho.org/en/documents/ultra-processed-food-and-drink-product-sale...PAHO research establishes dose-response relationship between ultra-processed food consumption and NCD incidence. Caribbean studies show ultra-processed food sales predict obesity and diabetes rates with r=0.87 correlation.
Causal mechanism: idle land → 80% food import → ultra-processed food dominance → NCD incidence. Activation of idle land breaks this chain by increasing affordable fresh food availability.
