Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: A historian in Ecuador rediscovered and rebuilt a 1,000-year-old water management system from the pre-Incan Paltas civilization, bringing reliable water to drought-prone communities across the region.
📈 One key stat: The project has increased Catacocha’s water availability from one hour to 10 hours daily, enhancing food security and resulting in the creation of 250 lagoons and tajamares.
💬 One key quote: “Water is a constitutional right for all. Yet, how do you provide it to a rural community that may be in debt and lack the cashflow to carry out projects?” asks Vilma Collaguazo.
1️⃣ The big picture: Galo Ramón, a historian from Catacocha in southern Ecuador, discovered an ancient water management system while studying a map from 1792. The system was created by the pre-Incan Paltas civilization over 1,000 years ago to collect and manage water in a semi-arid region with unpredictable rainfall. After decoding historical documents and local myths, Ramón and his foundation rebuilt the lagoon system starting in 2005. The restored system now helps communities overcome severe water shortages through a network of artificial wetlands, small dams, and strategic planting that allows water to infiltrate slowly into the ground, recharging aquifers and providing year-round water access.
2️⃣ Why is this good news: The revived water system brings reliable water to communities that previously had access for only half an hour daily. Local residents now enjoy water for up to 10 hours per day, supporting gardens and livestock in an area prone to severe droughts. The project demonstrates how ancient knowledge can address contemporary challenges without massive infrastructure investments. The ecological benefits extend beyond water access, as the system has led to reforestation with native plants that conserve moisture and protect slopes. This success story provides a model for other regions in Ecuador and around the world struggling with water scarcity and limited resources.
3️⃣ What’s next: Local advocates hope to convince Ecuador’s government to invest in rebuilding similar systems throughout the country as a practical solution to water scarcity. The Catacocha model shows potential for addressing both drought and flood management across Ecuador. Researchers continue documenting how recovering ancestral knowledge can provide sustainable water solutions that don’t require enormous financial resources.
