Can outsider beavers save this dried up river?

It's not easy being a river in the desert under the best of circumstances. The ecosystem exists in a very delicate balance, allowing water sources to thrive in the harsh conditions. These water sources in otherwise extremely dry areas are vital to the survival of unique wildlife, agriculture, and even tourism as they provide fresh drinking water for the people who live nearby.

But man-made problems like climate change, over-farming, and pollution have made a tough job even tougher in some areas. Rivers in Utah and Colorado that are part of the Colorado River Basin have been barely surviving the extremely harsh drought season. When the riverbeds get too dry, fish and other aquatic creatures die off and the wildfire risk increases dramatically.

About six years ago, one team of researchers had a fascinating idea to restore the health of some of Utah's most vulnerable rivers: Bring in the beavers.

In 2019, master's student Emma Doden and a team of researchers from Utah State University began a "translocation" project to bring displaced beavers to areas like Utah's Price River, in the hopes of bringing it back to life.

Why beavers? It just makes dam sense! (Sorry.)

Beaver dams restrict the flow of water in some areas of a river, creating ponds and wetlands. In drought-stricken areas, fish and other wildlife can take refuge in the ponds while the rest of the river runs dry, thus riding out the danger until it rains again.

When beavers are present in a watershed, the benefits are unbelievable: Better water quality, healthier fish populations, better nutrient availability, and fewer or less severe wildfires.

It's why beavers have earned the title of "keystone species," or any animal that has a disproportionate impact on the ecosystem around them.

Doden and her team took beavers who were captured or removed from their original homes due to being a "nuisance," interfering with infrastructure, or being in danger, and—after a short period of quarantine—were brought to the Price River.

Despite the research team's best efforts, not all the translocated beavers have survived or stayed put over the years. Some have trouble adapting to their new home and die off or are killed by predators, while others leave of their own accord.

But enough have stayed and built dams since 2019 that the team is starting to see the results of the effort. In fact, beaver projects just like this one have been going on all over the state in recent years.

The water levels in the river are now the healthiest they've been in years. The fish are thriving. Residents of Utah are overjoyed at the results of the experiment.

A column in The Salt Lake Tribune from 2025 (six years after the beaver translocation began) writes that the revitalization of the Price River "helped save our Utah town."

"A tributary of the Colorado River, the Price River runs through downtown Helper. On a warm day, you’re likely to find the river filled with tourists and locals kayaking, tubing and fishing along its shore. A decade ago, it was hard to imagine this scene—and the thriving recreation economy that comes with it—was possible."

Of course, it wasn't JUST the beavers. Other federal water cleanup investments helped remove debris, break down old and malfunctioning dams, and place tighter regulations on agriculture grazing in the area that depleted vital plant life.

But the experts know that the beavers, and their incredible engineering work, are the real MVPs.

In other drying, struggling rivers in the area, researchers are bringing in beavers and even creating manmade beaver dams. They're hoping that the critters will take over the job as the rivers get healthier.

Utah's San Rafael river, which is in bleak condition, is a prime candidate. In on area of the river, a natural flood inspired a host of beavers to return to the area and "riparian habitat along that stretch had increased by 230%, and it had the most diverse flow patterns of anywhere on the river," according to KUER.

It's hard to believe that beavers nearly went extinct during the heyday of the fur trapping industry, and continued to struggle as they were considered nuisances and pests. Now, they're getting the respect they deserve as engineer marvels, and their populations have rebounded due to better PR and conservation programs.

To that I say...it's about dam time!

Ancient Hawaiian land system could transform sustainability's future—and it’s going viral

Welcome to the world of Ahupua’a.

Ancient Hawaiians were agricultural masters.

Switch to electric, use less water, recycle everything: in a time when fighting climate change seems insurmountable, an incredible solution is re-emerging from the ancient past—and it’s making major waves on TikTok. The ahupuaʻa system, Hawai’i’s approach to land management before the once-sovereign nation was colonized, is shocking the world as people discover its incredible potential to revolutionize sustainability—and potentially solve our modern climate crisis.


@ben_jamin_witu You cannot convince me we are more technologically advanced when ancient societies used nature as their technology and balanced themselves for thousands of years. VC: Hyperspective on IG. #landback #foodsoverignty #indigenous #wisdom #tiktok #fyp ♬ Lights Are On - Instrumental - Edith Whiskers

Meet Benjamin Kaimipono (@ben_jamin_witu), a Native Hawaiian (Kanaka ‘Ōiwi) TikTok creator whose videos—some original, some reposts—about Native Hawaiian life, practices, and history are creating a vitally important tapestry of a culture erased. One of the videos, a repost from @hyperspective on Instagram, (a boutique creative agency in Honolulu) depicts a simulated version of the Hawaiian ahupua’a system with the caption: “You cannot convince me we are more technologically advanced when ancient societies used nature as their technology and balanced themselves for thousands of years.”

The responses are filled with pride, respect, and wonder. One commenter wrote, “This is why land back is crucial today with global warming at an all-time high! Indigenous peoples are in tune with the land and know better than anyone else how to take care of it ✊🏽.” Others appreciated Kaimipono's sharing of Native Hawaiian knowledge, with one person writing: “This... is the proper use of the 'āina. live and learn and always Aloha 'Āina. Proud to be Hawaiian. Ha'aheo au. 😎🤙🏾” (According to Lāna'i Culture & Heritage Center, “'āina” is generally translated as “land” but directly means “that which feeds”; “Ha'aheo au” means “I am proud.”)

Another wrote:

“Hawaiians understood what it meant to live righteously off the land, and we're centuries ahead of their time with resource management. There's connection to the land is a key value. That's why native cultures always knew how to be sustainable with the resources they had, and didn't overuse or destroy it.”

Why this ancient system works

The ahupua’a system, which thrived in Hawai’i for nearly a millennium between 1000 CE to 1848, wasn’t just smart—it was mathematic, geologic, and climatic genius. Picture this: 725 perfectly organized sections across eight islands. Each land parcel averages 5,678 and works in perfect harmony with nature. It was symbiosis at its finest: each ahupua’a operated like a self-contained utopia, combining forests, crops, and fishing zones, demonstrating a master class in resource management. This way, Hawaiians were able harness the power of the ecosystems around them while both supporting the 800,000 people living on the islands (and growing) and maintaining the land’s integrity.

In their seminal paper, “The Ahupua’a as a Traditional Hawaiian Resource Management Model for a Sustainable Coastal Environment,” researchers David W. Blane and Christopher Chung describe the ahupua’a as “a practical and rational approach to resources management that conforms with the existing geography and its resources rather than altering them for human convenience,” adding:

“…as you may already have surmised, the ahupua‘a means much more. The ahupua‘a embodies a unique relationship between the Hawaiian people and the land as well as the practical and rational approaches applied to insure the sustainability of the natural environment from overexploitation, pollution, and extinction.”

Land management magic

This could get very scientific very fast, but here’s the simple version: ahupua’a were wedge-shaped land units that spanned from the mountains (mauka) down through the cultivated lowlands (mala) to the sea (makai). This way, each unit, each slice, had everything they needed to survive: forests to harvest wood from and collect bird feathers; irrigated agricultural terraces (lo’i) where they mostly grew taro, and dryland farms used to cultivate sweet potato (’uala), coconuts (niu), breadfruit (’ulu), and bananas (mai’a), just to name a few. Each ahupua’a also contained a coastal and marine area, where Hawaiians could fish and produce salt.

The leadership structure was also pure brilliance: each ahupua’a had its own chief (ali’i), overseer (konohiki), and priests (kahuna) who worked together, overseeing the administration of their land and ensuring that resources were used efficiently and sustainably. But perfection on this scale takes more than just good delegation; the ahupua’a leadership also incorporated important Native Hawaiian values like respect (aloha), cooperation (laulima), and stewardship (mālama) to ensure that everything remained balanced (pono). According to the North Shore Sustainable Communities Plan, here’s what made it all work:

  • When resources ran low, they immediately stopped harvesting to preserve resources.
  • They closed certain fishing areas seasonally so fish populations could bounce back.
  • Inter-ahupua’a trade was commonplace, so residents felt connected, and the system kept strong.

"The Hawaiians believed that the land, the sea, the clouds and all of nature had a certain interconnectedness, which is why they used all of the resources around them to reach the desired balance in life." - Nation of Hawaii

As we watch our food systems fall apart, coastlines disappear, and farmlands struggle, remember: it doesn’t have to be this way. Modern urban planners could take a page out of the ancient Native Hawaiian’s book, as they construct our future cities, structures, and systems. No one is asking for a 180 total rehaul or a return to 1848. But there are small things we can do. In Hawai’i, they’ve already brought a few of these principles back to life. They’re restoring traditional fishponds, reconnecting forests with their corresponding coastal areas, and empowering local communities to steward their own resources. This is a real, sustainable way forward. Or, as the BBC said: “The ahupuaʻa system of land development, in practice for more than 1,000 years, has the potential to show the world a new path to sustainability." Are you ready to be a part of that change?

Walking Alongside Martu: A journey with one of the world’s oldest living cultures

Pura’s inaugural impact collection honors both sacred traditions and sustainable futures.

James Roh
True

In a world driven by speed, efficiency, and immediate results, it’s easy to forget that lasting change is built on trust. Real impact doesn’t come from rushing toward an end goal or measuring success through lofty metrics. It comes from falling in love with the problem, building a community around it, and sharing a vision for lasting transformation.

Pura, the smart home fragrance company that marries premium fragrance with innovative technology, recently launched its inaugural impact collection with K Farmer Dutjahn Foundation (KFDF) and Dutjahn Sandalwood Oils (DSO). The Pura x Dutjahn partnership began with a clear purpose: to source a sacred ingredient directly from its origin while honoring the land and the people who’ve cared for it. Our goal wasn’t simply to find sandalwood — it was to find a community and an ingredient that embody exceptional land stewardship, ethical harvesting, and transformative, community-led impact. After careful research and over three years of development, we saw an opportunity to secure a premium, luxurious ingredient while supporting a regenerative supply chain that invests in Indigenous-led education, economic opportunity, and land stewardship.

Over the past several years, we’ve walked alongside Martu, an Indigenous tribe from the vast Western Australian desert. Martu are one of the oldest living cultures in the world, with a history spanning 60,000 years. As nomadic hunter-gatherers, they have unparalleled ecological knowledge, passed down through generations, making them the traditional custodians of the land. Their approach to sandalwood harvesting isn’t driven by market demand but by a deep respect for seasonal rhythms, land health, and cultural law. Their work adapts to the environment—whether it’s “sorry time,” when mourning pauses activities, or the harsh desert conditions that make travel and communication difficult. Martu operate on Martu time, a deliberate rhythm shaped by millennia of experience, far removed from the rapid-swipe, hyper-productive pace of Western systems.

Martu’s ecological knowledge isn’t documented in baseline reports. It’s lived, carried in stories, and practiced with rigor and respect for the changing needs of the ecosystems. True partnership means unlearning the typical approach. It means standing beside—not in front—and recognizing that the wisdom and leadership we need already exist within these communities. Our role isn’t to define the work, but to support it, protect it, and learn from it.

James Roh

Tonight, as I spoke with Chairman Clinton Farmer and the KFDF team about our focus for this piece, I learned that Clinton’s truck had broken down (again), leaving him to “limp” back to town from the desert at low speeds for hours and hours. He had been awake since 3:00 a.m. This is a common and costly setback, one that disrupts the harvest, demands days of driving, and brings real financial and emotional strain. These barriers are relentless and persistent, part of the harsh reality Clinton and his community face daily. It's easy for outsiders, detached from the reality on the ground, to impose rules, regulations, and demands from afar. Rather than continuing to impose, we need to truly partner with communities — equipping them with the resources to operate sustainably, avoid burnout, and protect the very land they love and care for. All while they endeavor to share these incredible, sacred ingredients with the world and build an economic engine for their people.

There is much to learn, but we are here to listen, adapt, and stay the course. The future we need will not be built in quarterly cycles. It will be built in trust, over time, together.

How Kamikatsu became the first zero-waste town in Japan, and what we can learn from them

Meet the tiny town that's radicalizing the ways we recycle.

Anyone can transform their relationship with waste.

In Japan, one of the first things you notice is how intense they are about recycling. Bins are guarded by two to three uniformed protectors who are quick to tell you if you’re doing things wrong. For a novice—especially one from America—that seems to be almost everything. The plastic plate wasn’t washed clean enough, you’re headed to the wrong bin (there are many, all with varying purposes), etc.. It can feel quite exhausting until you realize that Japan is a global leader in plastic bottle and e-waste recycling, with an impressive 86% and 70%, respectively. Compare that to the global recycling numbers: according to the Ellen MacArthur Foundation, about 30% of plastic water bottles (PET) are recycled globally and only 22% of all e-waste is formally recycled globally.

However, nestled in the lush mountains of Shikoku Island—the smallest of Japan’s four islands—is a tiny town that’s revolutionizing the trash and recycling industry. Welcome to Kamikatsu. All 1,400 residents here are so committed to zero-waste, they sort their garbage into 45 different categories and don’t even use garbage trucks. And their efforts have paid off: Kamikatsu received a remarkable 81% recycling rate—the highest in the world, thus far.

Recyling, reusing, environment, Japan, environmentKamikatusu's recycling techniques are well worth the effort. Kamikatsu Zero Waste Center

For perspective, Japan’s national average (for overall solid waste recycling) is only 20%. Germany is considered as the global leader in recycling household and municipal waste, with a recycling rate of 67%. Following Germany are Austria (58%), South Korea (59%) Slovenia (58%), and Belgium (54%). The United States rests at 32%, although it aims for 50% by 2030. In short, Kamikatsu isn’t just lapping the world’s global leaders: it’s redefining what’s possible.

Which wasn’t always the case. In the 1970s, there was nothing exceptional about Kamikatsu, in terms of recycling. According to ReasonsToBeCheerful: “The roots of Kamikatsu’s reuse revolution go back decades. During Japan’s postwar economic boom, the expansion of mass industry created huge amounts of waste, which increased from 6.2 million tons in 1955 to 43.9 million tons in 1980. In response, municipalities across Japan, including Kamikatsu, began to build incinerators to dispose of it all. But over time, concern grew about the pollution being created.”

The town’s transformation took years, beginning in 1991, when officials first tackled food waste by providing composters to every household. By 1997, they’d created nine categories for recycling:

  1. Newspapers
  2. Magazines and flyers
  3. Cardboard
  4. Milk cartons
  5. Other paper
  6. Aluminum cans
  7. Steel cans
  8. Glass bottles
  9. PET bottles

This was the moment that changed everything for Kamikatsu, a significant cultural and logistical shift that laid the foundation for years to come. "It was tough because it changed their day-to-day duties," admits Akira Sakano, founder and director of Zero Waste Japan, "but people got used to it."

Today, Kamikatsu continues its goal to become fully zero-waste. The town closed down their incinerators, removed all garbage trucks, and now boasts a radical 45 categories for recycling.

But do you really need a 45-category system to cut back on waste? Of course not. Here are five practices anyone can adopt at home:

  1. Compost your food waste. According to Kamikatsu’s garbage guide (which was helpfully translated by Core77), “Compost food scraps [is] the only resource you can recycle yourself.” By using compost bins, electric composters, and bamboo composters, residents are able to transform food scraps into valuable fertilizer.
  2. Embrace second-hand. The town has a “Kuru-kuru” shop, which translates to “come and go,” and offers free second-hand items to anyone who wants them. Each product is weighed and tracked, to account for exactly how much waste is avoided. To do this locally, try joining your neighborhood’s Buy Nothing group, or donate to a Tiny Free Library.
  3. Get creative with upcycling. Local artisans in Kamikatsu transform old clothes, like kimonos, and koinobori (fish-shaped streamers) into bags, jackets, and toys. So, ask yourself: Do I really need to throw away that jar, or could it become a treasured container? Old t-shirts could become lovely, braided rugs. Egg cartons make wonderful painted art projects or storage bins.
  4. Reuse your own containers. Places like The Refill Shoppe, Common Good, and Clean Cult offer green alternatives to single-use cleaning solutions and soaps. Their wide variety of refillable products also use less packaging and contain non-toxic ingredients.
  5. Question consumption. The Kamikatsu Zero Waste Center is shaped in a giant question mark, urging people to ask why they must spend money on something. Their website reads: “Why do you buy it? Why do you throw it away?” It’s a reset, an invitation to rethink your relationship with constant consumption.

As we face mounting environmental challenges, Kamikatsu offers a powerful reminder: with community commitment and creative thinking, we can transform our relationship with waste. Are you ready to try?
