The arrival of rain as a blessing is among the oldest human stories there is.

In Botswana, water and wealth are two names for the same blessing. Pula is the name of Botswana’s national currency, indicating the drought stricken land’s emotional relationship to water.

We see the emotional representation of rain in African American blues traditions, rainmaking rituals in West Africa, monsoon folk songs across South Asia, and Indigenous rain-dance ceremonies. Across cultures for millennia, rain has equaled relief.

But today, human-driven land degradation is rewriting that story.

What if instead of waiting for landscapes to collapse to pay the costs, we invested in the resilience of those very landscapes?

In many of the world's most arid and semi-arid regions, rain is no longer arriving as a blessing but as disaster.

To understand why, we need to look at the ground rather than the sky.

When the Sponge Hardens

If we look at the Earth's surface now, versus 100 years ago, we'll see that most of the land has been transformed from natural ecosystems to concrete, agricultural, and productive land. This is the process of desertification.

You may think of desertification through familiar cultural images such as advancing sand dunes swallowing settlements, cracked earth stretching to the horizon, and vegetation fading into absence. But the defining characteristic of desertification is not simply a lack of water. It is the loss of a landscape's ability to hold water.

Healthy soil functions like a sponge. Built from organic matter, fungal networks, plant roots, insects, and billions of microorganisms, it can absorb and store enormous quantities of water. When rain falls, much of it infiltrates the ground, replenishing soil moisture and underground aquifers. The water moves slowly through the landscape and across layers of soil, sustaining rivers and vegetation long after the storm has passed.

However, degraded soil behaves differently.

Decades of intensive cultivation, overgrazing, vegetation loss, repeated tillage, and use of synthetic inputs reduce soil organic matter and weaken the soil food web. As soil structure deteriorates, the ground becomes compacted and hardens. Pores that once allowed water to penetrate collapse. Rain can no longer soak in. So, when a heavy rainfall arrives, the water cannot penetrate the ground and flushes all that lays on the surface.

Instead of absorbing the water, the soil lets it run downhill. Small rivulets become torrents. Topsoil is stripped away. Gullies form. Streams rise rapidly, and rivers burst their banks. The same rainfall that would once have been absorbed by the landscape becomes a destructive flood.

Farmers and Communities on the Frontlines

At Commonland, we work with communities to restore landscapes that have been identified as degraded—places where decades of ecological decline have reduced the land's ability to support communities, livelihoods, and biodiversity. We aim to provide those communities and local organizations with the means to reverse the cycle of degradation and contribute to regenerating the landscapes they live in and depend on. However, reversing the effects of decades of landscape degradation is not an easy ride.

Over the past 18 months, two of those landscapes, on opposite sides of the world in Spain and South Africa, have delivered the same warning: Without healthy ecosystems, our social, economic, and financial systems collapse.

In the Spanish town of Grazalema, where around 1,500 people are nestled in the mountains of Cádiz, the 2026 January rains shattered records. The landscape, as a result of decades of intensive land use, had lost much of its ability to absorb and regulate water. Aquifers filled rapidly. Water began emerging through the ground itself, threatening the ancient karstic system on which the village sits. Gullies opened across farmland, roads disappeared, and the entire town was evacuated for 10 days.

We have funded the degradation of the systems that protect us, while calling it productivity. The rains are now sending the invoice.

For local farmers, the damage was not only immediate but cumulative. Fields were washed out or left waterlogged, making planting impossible. Topsoil was stripped away, taking with it both fertility and future yield potential. Livestock grazing areas were damaged or cut off, feed stores were lost or became inaccessible, and seasonal cycles were disrupted beyond repair for the year.

“The economic damages for all our activities have been very high,” says Carmen Bueno, owner of the regenerative farm Tambor del Llano. Bueno is also a member of Asociación Serranías Vivas, a local association that brings together farmers, land managers, and rural stakeholders working to restore and protect the Sierra de Cádiz landscape through more sustainable land use and coordinated landscape restoration efforts.

More than 8,000 kilometers away, another landscape faced a sadly similar story.

In May 2026, catastrophic flooding tore through the Langkloof and Baviaanskloof valleys on South Africa’s Eastern Cape. After months of droughts drying up the land, the floods washed everything away: from fields, to tarmac roads, as well as wetlands. For many households, this meant more than infrastructure loss—it meant isolation. Local communities could not move out of their house, let alone the valleys; food and water supplies could not be accessed; farm produce could not........
