What If We Restored One Billion Hectares? Costs, Labor, and Yield
Restoring one billion hectares of degraded land isn’t just an ambitious environmental goal—it’s a monumental undertaking that could reshape ecosystems, economies, and even the climate. But what exactly would it take to pull off something on this scale? What kinds of costs, labor, and yields are we talking about? Pull up a chair and let’s unpack this sprawling question piece by piece, because thinking about this at a human scale helps illuminate the real challenge—and opportunity—behind so-called “land restoration.”
Why Restore a Billion Hectares?
It’s hard to grasp a billion hectares. To put it in perspective, that’s roughly the size of the United States. Worldwide, degraded lands—places where soil quality has plummeted, vegetation is sparse, and biodiversity is suffering—are estimated to cover about 2 billion hectares. Restoring half of that could be a game-changer in tackling climate change, boosting food security, and saving countless species.
Nature-based solutions make sense, don’t they? Trees absorb carbon dioxide. Healthy soils and forests regulate water cycles. Restored lands can boost livelihoods for rural communities. But this isn’t gardening in your backyard. It’s a global-scale restoration requiring serious resources.
What Would Restoration Look Like on This Scale?
Restoration isn’t a single fix. It varies from reforesting degraded woodlands, regenerating grasslands, rehabilitating wetlands, to implementing sustainable agriculture. Each type of restoration has its own time frame, cost structure, and labor demands.
Imagine a patchwork quilt across continents. In some places, natural regrowth might work, where you protect land and let nature do its thing—minimal labor, but maybe slower results. In others, especially heavily degraded or desertified areas, active intervention is needed: planting seedlings, building soil, controlling invasive species. That’s labor-intensive, with upfront costs but potentially faster, more reliable recovery.
Costs: What’s the Price Tag?
Financial studies estimate restoration costs can range wildly—from as low as $100 per hectare in areas with natural recovery potential, to upwards of $3,000 per hectare for laborious reforestation in drylands or tropical areas needing intensive care.
So, restoring a billion hectares might cost anywhere from $100 billion on the low end to over $3 trillion at the high end. That’s a staggering range. On average, many experts peg the number near $500 to $1,000 per hectare, putting the global price tag in the ballpark of $500 billion to $1 trillion.
Where would this money even come from? Governments, international organizations, private investments, and, increasingly, innovative financing like green bonds and carbon markets. Projects need upfront money but generate benefits over decades—cleaner water, carbon sequestration, biodiversity, and jobs.
Labor Demand: Who’s Going to Do This Work?
One thing often overlooked is labor. Restoration can be a huge job creator. Planting trees, seeding grasses, controlling erosion, and monitoring sites demand people on the ground.
Let’s say, on average, active restoration requires 1 to 5 full-time person-months per hectare over the initial stages—planting and early maintenance. That’s roughly 83 million to 416 million person-years of work just for those first steps.
Is there a workforce to match this? In many rural areas, there are millions of people underemployed with agricultural backgrounds who could be mobilized. Restoration programs could offer meaningful employment, especially in developing countries where job opportunities are often scarce.
Training, fair wages, and community engagement become vital ingredients. Simply throwing money at the problem won’t cut it; these projects must empower local populations, respecting their knowledge while introducing scientific methods.
Expected Yields: The Benefits Beyond Trees
Yield doesn’t just mean timber or crops. Restored land yields ecosystem services: carbon capture, improved soil health, water filtration, and biodiversity—each harder to put a dollar figure on, yet vital.
Some estimates suggest that restored lands could sequester up to 205 gigatons of carbon over coming decades. To give you a sense, that’s equivalent to roughly 20 years of global fossil fuel emissions at current rates. The climate mitigations alone could justify large restoration investments.
Agricultural yields might increase too. Land restoration improves soil fertility and moisture retention, making farming less vulnerable to droughts. This benefits food security for millions, especially in regions prone to desertification.
Challenges and Pitfalls to Watch Out For
Restoration on this scale won’t be smooth. Economic and political instability, land tenure conflicts, and ecological uncertainties can undermine projects. Past efforts sometimes failed when local communities were excluded or when monoculture plantations replaced diverse ecosystems.
It’s crucial to avoid “greenwashing” with superficial tree planting. Dark side practices include planting non-native species that consume scarce water resources or displacing indigenous people. Restoration must be about resilience, not just quick carbon accounting.
Restoration and Climate Change: A Two-Way Street
Climate change complicates restoration. Altered rainfall patterns, higher temperatures, and increased extreme weather events make rehabilitating land trickier—and more urgent.
But restored land itself can be a powerful climate ally. Not only does it soak up carbon, it buffers ecosystems and communities from climate shocks.
That’s why international frameworks like the UN Decade on Ecosystem Restoration (2021-2030) emphasize restoration’s role in climate adaptation and mitigation.
Economic Multipliers: More Than Just Environmental Returns
When considering costs, remember the ripple effects. Restoration stimulates rural economies through job creation, boosts agricultural productivity, and reduces disaster risk, lowering expensive relief and repairs in the future.
A World Resources Institute report showed that $1 invested in restoration can yield up to $7 in economic benefits over time. So while the upfront costs are massive, the returns spread wide across society.
Getting Involved: What Can Individuals or Organizations Do?
Big picture restoration efforts hinge on national and international action, but individuals can contribute too. Supporting sustainable products, donating to credible reforestation NGOs, or even engaging in local restoration projects helps build momentum.
Educating ourselves and others about the importance of healthy ecosystems also creates a culture willing to fund and prioritize restoration.

Final Thoughts: What’s the Verdict on Restoring a Billion Hectares?
It’s a gargantuan task fronted with equally huge opportunities. The costs in dollars and labor are jaw-dropping, but so are the potential benefits—climate stability, food security, economic uplift, and planetary health.
This isn’t just about planting trees or letting barren land sit. It demands smart investments, community engagement, science-based methods, and a long-term mindset. The scale of ambition matches the scale of the crisis we face with climate change and biodiversity loss.
Whether we step up to restore a billion hectares might well define the environmental legacy of this generation.
