Antonio Nobre – If nature were a bank it would have been saved already

A conversation with Antonio Nobre, Brazilian agronomist by training and world’s leading Earth scientist, serving as the scientific director of the Biotic Pump Greening Group. He has dedicated his career to studying the Amazon’s ecological dynamics and its crucial role in climate regulation and is an expert on water cycles, native Indigenous knowledge, and much more.

We talk about how Antonio found his way to the Amazon after being born and raised in São Paulo, how he rebelled against the Green Revolution during his time at agricultural university, and how he discovered the incredible workings of forests—especially rainforests.
We also explore the overview effect—the transformative experience of seeing Earth from space—and how it often turns astronauts into environmental activists.

Ali Bin Shahid, one of the few who can model and calculate water cycle restoration

A conversation with Ali Bin Shahid, an engineer with a deep background in permaculture (and a military one too), a passion for modelling and one of the very few people using data and engineering approaches to tackle critical questions about regeneration. We explore how to put numbers to abstract ideas like slowing water down, spreading it, and soaking it. What does “slow” actually mean? How do we measure it—by kilometres per hour, or some other metric? How much regeneration is required to restore rivers or trigger rains in a given landscape? And, for example, where globally do we have the biggest potential? Where is the biggest gap between the forest and water potential and the current situation on the ground?

It’s definitely possible to manage a few acres or a few hectares through observation, if you’re there for many decades or even through different generations. But as soon as we start talking about regeneration at the landscape level, we need numbers. We need numbers and models. Surprisingly, a lot is already possible: we can calculate to a relatively detailed degree, what certain flows of air, water, and moisture will look like in a landscape. This means you can start to calculate and imagine, almost at a parcel level, where we need to regenerate in order to restore, for instance, summer rains and year-round rivers.

The surprising part is how few people are doing this work. Ali is trying to quantify these ideas: how much water to slow, where the global potential lies, and the vast gaps between current conditions and what’s achievable.

Jesús Areso Salinas – Building towers to trigger rain, to help nature sweat and cool

A conversation with Jesús Areso Salinas, retired from work as patent examiner at the European Patent Office and now active with his project to fight climate change combining water, katabatic tower and moisture. Another record-breaking summer in the global north, where temperature records were shattered repeatedly, prompts us to ask: is there a sustainable future for places like the Mediterranean? Jesús wondered how does nature cool? and, crucially, could we help nature kickstart the cooling of ambient air?”

Imagine cooling our surroundings during a heatwave—cooling town squares, vegetable gardens, or farms on a small scale. What if, over time, this approach spreads, with more people cooling their surroundings, allowing plants and trees to continue growing through the summer and helping to cool the air? Could this restoration of local cooling contribute to rebalancing water cycles, bringing back summer rains, and even creating a lasting cooling effect? These are big, almost magical questions, and they are exactly why we tackle them here with Jesús, an engineer turned permaculture expert, who is now building towers to help nature “sweat” and cool.

Sure, we could retreat to air-conditioned spaces, but air conditioners only worsen the problem by using energy to move heat from inside to outside without solving anything at its core. And what about plants, trees, and animals? They need a humid, comfortable environment to thrive, yet during hot, dry summers, they’re focused on survival rather than growth—or the cooling process essential to their function. Mediterranean farmers, in particular, take note: during the peak of summer, your plants and trees often stop growing because it’s too hot and dry.

So, how does nature cool itself? Through transpiration, plants and trees release moisture, which cools the surrounding air. However, as heatwaves become stronger, it’s often too hot for them to function, meaning they can neither grow nor cool the air. This lack of cooling is a problem farmers and investors need to understand—especially those in warmer climates, where plants and trees may be unable to photosynthesize or grow for weeks. Cooling ambient air is essential, and air conditioning isn’t the answer.

Our Vital Role as Keystone Species in restoring Water Cycles

The disparity in attention between water vapour, constituting 60–70% of the greenhouse effect, and CO2 at 25%, prompts a crucial question: why is water vapour seldom discussed in climate discourse? Perhaps because addressing its role requires extensive global reforestation and regeneration efforts across the planet.

Do we even have the imagination needed to restore marshes, mangroves, and perennial pastures with trees, and strategically reforest and revitalise ecosystems?

This approach- the intentional large-scale intervention in the Earth’s climate system to counter climate change, called climate engineering- highlights humanity’s urgent role in environmental conservation and restoration. The call to action is clear.

Rodger Savory – Restore the water cycles and reverse desertification in California, regenerating 150.000 acres with 600.000 cows

A conversation with Rodger Savory, ecologist, land manager, and ranch owner, about scale and cows, how to kickstart regeneration in desert situations, changing local weather patterns, abundance, soil bacteria, conventional agriculture, WW2 and much more.

Ichsani Wheeler and Lenka Danilovic – How to make water our friend again thanks to hippies with satellites and indigenous water management

A conversation with Ichsani Wheeler and Lenka Danilovic. Ichsani is a scientist, co-founder of OpenGeoHub and EnvirometriX, while Lenka is an hydrologist and intern at OpenGeoHub. In this conversation, we talk about the world of remote sensing, and we unpack what the eyes in the sky can help us learn about indigenous land and water management.

Tim Coates – Sell flood mitigation to institutional players to finance water cycle restoration

A conversation with Tim Coates, co-founder of Oxbury Bank, the UK’s only specialist agricultural bank, about flood risk mitigation, water quality, water cycle restoration, selling flood mitigation to institutional investors and much more.

Anastassia Makarieva – Healthy forests invest their capital to create their own rain

A conversation with Anastassia Makarieva, researcher at the Petersburg Nuclear Physics Institute and with a fellowship at the University of Munich, about how healthy ecosystems, and specifically healthy forests, regulate moisture and thus rain. We discuss tipping points and where to look for wet spots even in very dry landscapes.
