Combines Food Security, Cash Crop, Environment and Carbon Drawdown

at unmatched Price and Effectivity

Abstract

The 7BIO Breadfruit GeoEngineering concept proposes a globally scalable, cost-efficient carbon removal solution rooted in regenerative agroforestry. By planting 7 billion micropropagated breadfruit trees across pre-existing farmland, the project aims to sequester between 4.7 and 9.4 Gt of CO₂ over a 10-year span—purely through aboveground wood biomass, without land conversion, invasive species, or fossil fuel dependency. Including broader ecological effects and longer timeframes, true costs may drop below $1/t CO₂.

In contrast to high-tech carbon capture solutions, 7BIO is low-input, grassroots-compatible, and supports food security, soil restoration, and rural resilience. The system builds on traditional ecological knowledge, accelerated by modern propagation methods and decentralized micro-infrastructure.

As both a climate and socio-economic solution, 7BIO prioritizes natural system alignment over industrial abstraction, representing one of the most viable and just options currently available for atmospheric carbon drawdown.

▸ Concept:





After 10 years, 7 billion micropropagated breadfruit trees privately planted on pre-existing agricultural land—in an interspersed, eco-friendly agroforestry system—will reliably remove >9.45 Gt of CO₂ (minimalistic scenario a¹) or at the very least 4.73 Gt (catastrophic scenario b²) at a cost ranging from approx. $14.81/t CO₂ (a) to $29.62/t CO₂ (b)
(i.e., $54.35/t C (a) to $108.71/t C (b))—solely in their aboveground wood biomass in the form of non-volatile carbon. This does not yet include additive factors such as roots, abundant low-decomposition litter, soil carbon increases, lower fertilizer demands (e.g., less Haber-Bosch impact), lower pesticide use, reduced fuel consumption, and many other positive synergisms.

Including some of these synergistic factors extended over a 50-year period, 7BIO agroforestry reaches effectiveness as low as ~$0.67–1.11/t CO₂.

▸ Info: Cost Efficiency

Scenario	Cost	CO₂ Captured	Cost per t CO₂
a) Minimal	$70B	4.73 Gt	$14.81
b) Worst Case	$70B	2.36 Gt	$29.62

Over 50 years, effective cost may drop to ~$3.34/t CO₂ or less through tree propagation, low maintenance, and economic feedback loops.

(Impressive, as a mere side-product of global food security and sustainable development.)

▸ Financing

Cost efficiency of the 7BIO breadfruit system over 100 years (~2 cycles):

Years after planting	$/t C	$/t CO₂
10 years	$4.04	$14.82
50 years	$0.90	$3.34
100 years	$0.56	$1.66

The projected cost of planting and sustaining 7 billion breadfruit trees totals $70 billion. This does not need to be paid upfront or by a single entity—it will be financed and reimbursed step-by-step over several years, largely through self-sustaining economic momentum.

By comparison: that’s roughly the market value of companies like Activision Blizzard—or equivalent to about 70 solar plants at 1000 MW capacity (of which 18,000 would be required to meet global energy demand). Those 70 solar plants would offset ~0.07 Gt CO₂ annually, i.e., ~0.7 Gt in 10 years, compared to 7BIO’s 4.73–9.45 Gt CO₂.

7BIO shares the key advantage of being a profit-oriented system, where carbon sequestration is a side-effect.

The initial phase requires upfront investment—via public grants, donations, private sector contributions, or hybrids thereof—for micropropagation labs, distribution systems, breadfruit product development, and demonstration infrastructure (e.g., solar drying, milling). Once running, the system becomes self-financing via low-cost ($5–10) seedling sales and market incentives.

▸ Creating Demand & Publicity




The greatest barrier is breadfruit’s global obscurity. Farmers need reliable sales to justify tree maintenance.

To build market demand, large-scale awareness campaigns are needed, emphasizing:
• Nutritional and culinary value
• High yields and resilience
• Suitability for health-conscious markets
• Processing versatility (e.g., flour, snacks, bakery ingredients, pasta)

▸ Product & Nutrition Highlights
Breadfruit flour, crisps, puffs, biscuits, bakery fillers, thickeners, cereal blends, pasta, soup bases.

▸ Nutritional benefits: Rich in fiber, low glycemic index, gluten-free, satiating and suitable for health/weight-conscious diets, high quality protein.

A “Breadfruit Tastes & Types Assessment” event could be hosted at the National Tropical Botanical Garden (NTBG), which holds over 120 cultivars and extensive propagation experience. Varietal selection for taste, carbon yield, and robustness could be advanced there.

▸ Proof of Concept






7 Billion Breadfruit Trees in a 50:50 Agroforestry System (BF/Intercrops)

For preliminary estimates, we assume:

• 50 trees per hectare (very low-density)

• Target: 7,000,000,000 trees

• Required area: 140 million hectares (1.4 million km²)

• At 100 trees/ha: 70 million hectares (0.7 million km²)

• ▸ In comparison: Barley covers ~0.5 million km² globally, and there are about 37 billion fruit trees in over two million orchards worldwide.

Breadfruit thrives in ~14.8 million km² of optimal habitat (and potentially more), much of it already used as farmland.

▸ Info: Breadfruit Tree Features
• Artocarpus altilis
• Begin fruiting in year 2–3 (micropropagated)
• High production >50 years
• Lifespan: 80–100+ years
• Height: 18–30 meters
• Diameter: >1.2 to 1.8 m
• Fast growers: >20 m in <20 years
• Mostly seedless or nearly seedless
• Can be propagated traditionally after first cycle

▸ Carbon Removal Estimate


We base our calculation conservatively on aboveground wood biomass:

▸ Carbon Removal Parameters

Parameters	Values
MAI (timber volume)	9 m³/ha/year
Duration	10 years
Tree density	100 trees/ha
Area	70M ha
Conversion factor (Breadfruit vs Teak)	0.75
Breadfruit wood density	575 kg/m³
Carbon content	47.4% of dry mass

▸ Result:
→ 2.72 billion t dry matter
→ 1.29 GtC
→ 4.73 Gt CO₂

Catastrophic scenario (50% tree mortality):
→ 2.36 Gt CO₂

Note: These are very conservative estimates, excluding soil, root, intercrop and necromass effects.

▸ Risk Assessment:

7BIO Breadfruit Agroforestry does not fall into the usual controversial categories:

• Not reforestation sensu strictu — it targets existing private farmland, not forested areas.

• Instead of causing land use conflicts, it adds perennial tree components to farmland, increasing biodiversity and resilience.

• No incentive for forest clearing: Breadfruit yields are high, allowing localized systems to satisfy demand.

• Non-invasive yet highly competitive due to its agronomic, culinary, and ecological advantages.

• Land degradation countered: Breadfruit improves soil quality and water retention.

• Minimal maintenance costs and high resilience to neglect, especially when planted with the start of the rainy season.

• Propagation after first cycle can be farmer-controlled, reducing dependency on centralized seedling production.

▸ About 7BIOASIS


The 7BIOASIS Breadfruit Agroforestry System is:


• Grassroots-based
• Profitable
• Carbon-negative
• Biodiversity-supportive
• Suitable for smallholders, gardens, and even urban edges

Breadfruit trees can be planted at low density (e.g. 50 trees/ha) while maintaining full agricultural use of the land in between.

NGOs and government agencies can support the establishment of regional micropropagation labs, solar drying infrastructure, and logistics chains, all of which are self-refinancing once breadfruit-based products gain market recognition.

Over time, a self-sustaining loop emerges:

1. Infrastructure investment → 2. Increased supply → 3. Product development → 4. Consumer familiarity → 5. Market demand → 6. Tree adoption by farmers → back to 2...

▸ Breadfruit Advantages (Summary)


• Highly nutritious: low glycemic index, gluten-free, rich in fiber and high protein quality
• Early yield (year 2–3 for micropropagated trees)
• High yield over decades (50–80+ years)
• Fast-growing and robust
• Technologically feasible to dry, mill, and store (e.g. solar-dried flour)
• Strong carbon sink potential
• Intercrops well with other tropical food crops
• Non-invasive, non-GMO, culturally neutral
• micropropagated variants preferred for uniformity and vigour

Breadfruit has been overlooked primarily due to limited propagation, transport,processing and storage capacity, as well as lack of exportation opportunities—now solvable by modern methods.
