About This Article
This is Article 3 in the series The Sahelian Bocage – A Field-Tested Method for Landscape Regeneration. The first two looked at what the method is and where it fits geographically. This one turns to cost: how the bocage should be financed, and, more importantly, how its value should be judged.
The argument is simple. A restoration method should be measured by the landscape it keeps working over decades, not by what it costs to install in a single season. Read that way, the higher upfront cost that makes the bocage look expensive turns out to be the very thing that makes it worth financing, and the real economics only appear once you count in decades rather than seasons.
The Wrong Yardstick
Because the Sahelian bocage addresses the underlying causes of degradation rather than merely its visible symptoms, it inevitably costs more per hectare to establish than most restoration approaches.
The usual way to compare methods is cost per hectare treated. On that measure, a cheaper intervention that produces quick green cover, or other instantly quantifiable metrics, looks like the better deal. But the comparison relies on an assumption that rarely holds in dryland restoration scenarios: that every restored hectare is worth the same as every other.
That assumption is false. The problem is that the measures put into place – meant to keep the intervention alive – are often discontinued when funding cycles end or leadership changes. Additionally, sometimes the costs of upkeep are not factored in at all, and the same drivers that caused the degradation in the first place continue to wear the landscape down.
The Visible Figure: the Cost of Short-Term Success
The majority of dryland restoration initiatives are based on short-term success metrics that are clearly visible and measurable. What stays hidden is that continuity is not part of the equation.
Consequently, quite often, the same patch of degraded land is restored more than once – by different projects funded by different sponsors, years or decades apart, each booking it as a fresh success. Because no single budget carries the whole sequence, the real cost of restoring that land – the sum of all attempts – is never registered.
The Relevant Figure: the Cost of Continuity
A dryland restoration project does not end. The land that is recovered must be maintained indefinitely. Over time, this effort shifts from methodical restoration to methodical cultivation. What remains is the method. That is why it does not make sense to judge dryland restoration cost per hectare by the results produced in a few seasons. Instead, the cost must be distributed across a working life of several decades. That makes the upfront cost look very different.
Example: the perimeter, the most expensive single element of the Sahelian bocage method, costs about €1,200 per hectare. Spread over 50 years, two generations, it comes to €24 per hectare per year. Seen through this lens, the Sahelian bocage becomes, by far, more cost-efficient and effective than cheaper methods. And the honest figure is no longer the one-time cost to treat a hectare but the annual cost of keeping a hectare functional.
The higher upfront cost of the bocage buys the things that decide whether restoration lasts: the perimeter, the organization of the land, water management, the integration of production and the supervision of the farm over decades. These are not extras. They are what allows the landscape to keep functioning without being redone.
Result: the annual cost is low, and most of it is ordinary work: keeping the perimeter sound, pruning, clearing the water channels, tending what grows inside. It is done by the people who farm the land, as part of farming it, rather than by a project that has to be mobilized and paid to return. A landscape maintained this way does not depend on repeated funding cycles to survive.
Two generations is also about how long the method needs to take root. A perimeter built by one generation is farmed by the next as normal practice, and by the third it is simply how the land has always been worked, taught by parents and grandparents alike. By then it is no longer a method that has been introduced; it is simply how these communities farm.
Local Income During Construction
Part of the economic value of the bocage appears during construction, before the land produces anything. Building it is deliberately labour-intensive: the perimeter and earthworks are constructed by hand, using locally recruited crews rather than heavy machinery. This is the HIMO approach (haute intensité de main-d’œuvre – high labour intensity). Approximately 38% of the establishment cost is paid directly as wages to local workers.
That income also arrives when it is most valuable. Construction takes place during the dry season, when farming provides little work or income, and the wages are distributed across hundreds of locally recruited workers, each employed for only a few weeks. This spreads income widely throughout the community without disrupting agricultural production, while temporarily stimulating the local economy as those wages are spent on local goods and services.
Conventional accounting misses this entirely. The wages are recorded simply as project cost and counted against the method, rather than also being recognised as an immediate economic benefit to the surrounding community. As a result, the same €1,200 per hectare that makes the bocage appear expensive also contains a direct investment in local livelihoods long before the restored land begins producing environmental or agricultural value.
What a Functional Hectare Returns
Cost is only one side of the ledger. A working bocage hectare produces: crops and fodder year after year, better soil, water held in the ground rather than lost to runoff, and a buffer against drought that keeps output steady when it would otherwise collapse.
Those returns don’t stop at the field edge. Steady production supports local markets, keeps rural livelihoods viable, and holds communities in place on land that can still feed them. A full account of the method has to weigh this stream of value against the cost of producing it – not treat the cost in isolation.
There is also a return that appears only at scale. As restored hectares multiply and connect, they begin to function as a single larger unit, with hydrological, ecological, and productive effects that reach across a whole territory rather than a single field. The next article, Landscape Transformation, takes up that shift from hectare to territory
Restoration as Infrastructure – and Why Finance Misprices It
The clearest way to think about the bocage method is as infrastructure. We don’t judge a road by its construction cost alone, or a water system by the price of installation. We judge them by the service they provide over their lifetime. The bocage perimeter is the same kind of asset: it creates the physical and ecological conditions a landscape needs to stay productive, and its cost is justified by how long it goes on doing so.
This is where restoration finance struggles. Funding runs in short cycles – typically less than 5 years – while the landscapes it pays for are meant to work for decades. That mismatch systematically undervalues any method built to last, because the value shows up long after the funding cycle has closed.
Conclusion
For the Sahelian bocage, the economic question is not what it costs to restore a hectare of degraded land. It is what it is worth to build a landscape that keeps functioning – ecologically, productively, and for the people who depend on it – across generations.
This is Article 3 in the series The Sahelian Bocage – A Field-Tested Method for Landscape Regeneration. The next article, Landscape Transformation, examines how a network of bocage units creates new hydrological, ecological, and productive dynamics at territorial scale.
