We know that Bill Gates made a lot of money from Microsoft and since he left the company, he's been very busy spending it.
One of the latest projects he's funding is the Omniprocessor, which turns human waste into renewable energy and drinkable water. How drinkable? Gates demonstrated by drinking a glassful himself.
"I watched the piles of feces go up the conveyer belt and drop into a large bin," said Gates. "They made their way through the machine, getting boiled and treated. A few minutes later I took a long taste of the end result: a glass of delicious drinking water. The occasion was a tour of a facility that burns human waste and produces water and electricity (plus a little ash). I have visited lots of similar sites, like power plants and paper mills, so when I heard about this one—it’s part of the Gates Foundation’s effort to improve sanitation in poor countries—I was eager to check it out. The water tasted as good as any I’ve had out of a bottle. And having studied the engineering behind it, I would happily drink it every day. It’s that safe."
The Omniprocessor was created to simultaneously address the issue of poor sanitation in developing countries and their frequent lack of adequate drinking water and electrical power. Waste piles up in latrines or in open fields, or it's trucked away and dumped somewhere, maybe in a nearby body of water, causing the spread of disease. But western-style toilets require sewage lines and treatment plants that aren't feasible in many places. The Omniprocessor, designed by Seattle-area engineering firm Janicki Bioenergy, reinvents the sewage treatment plant.
In the Omniprocessor, sewer sludge is fed into tubes and boiled, producing water vapor which is purified for drinking. The dry solids are then fed into a fire, which creates steam to fuel a steam engine that drives an electricity-producing generator. That energy in turn fuels the machine, with excess available for other needs. The water burns the waste at temperatures of 1000 degrees Celsius, so high that there's no smell. The next generation of the machine could process waste from 100,000 people and produce about 22,700 gallons of drinkable water and 250 kilowatts of energy a day.
"If we get it right, it will be a good example of how philanthropy can provide seed money that draws bright people to work on big problems, eventually creating a self-supporting industry," said Gates. "Our foundation is funding Janicki to do the development. It’s really amazing to see how they’ve embraced the work; founder Peter Janicki and his family have traveled to Africa and India multiple times so they can see the scope of the problem. Our goal is to make the processors cheap enough that entrepreneurs in low- and middle-income countries will want to invest in them and then start profitable waste-treatment businesses."

Those entrepreneurs would make money from the sludge they remove from the environment, and the water and electricity they create.
Later this year, Janicki will set up the first Omniprocessor in the field in Dakar, Senegal.
"They’ll study everything from how you connect with the local community to how you pick the most convenient location," said Gates. "They will also test one of the coolest things I saw on my tour: a system of sensors and webcams that will let Janicki’s engineers control the processor remotely and communicate with the team in Dakar so they can diagnose any problems that come up. If things go well in Senegal, we’ll start looking for partners in the developing world."
"The history of philanthropy is littered with well-intentioned inventions that never deliver on their promise," he said. "Hopefully, these early steps will help us make sure the Omniprocessor doesn’t join the list."

Kaavan in Islamabad, Pakistan on Sept. 4, 2020. Arne Immanuel Bänsch / picture alliance via Getty Images
With help from music icon Cher, the "world's loneliest elephant" has found a new home and, hopefully, a new family.
<p>The elephant, a 36-year-old male named Kaavan, has lived alone in a controversial zoo in Islamabad, Pakistan since his partner Saheli died in 2012, according to <a href="https://www.ecowatch.com/tag/animal-welfare" target="_self">animal welfare</a> group <a href="https://www.four-paws.org/our-stories/press-releases/from-the-loneliest-to-the-luckiest-elephant-kaavan-takes-off-for-cambodia" rel="noopener noreferrer" target="_blank">Four Paws International</a>. But now, thanks to the efforts of Four Paws, Cher and her NGO <a href="https://www.freethewild.org/" rel="noopener noreferrer" target="_blank">Free the Wild</a>, the Pakistani government and American businessman Eric S. Margolis, Kaavan has landed in Cambodia after a 10-hour flight, where he will enjoy a new life in a <a href="https://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a> sanctuary.</p><p>"Kaavan was eating, was not stressed and he even slept a little bit whilst leaning on the wall of the crate!" Four Paws <a href="https://twitter.com/fourpawsint/status/1333328774507728896" target="_blank">tweeted Monday</a> of the successful flight. "He behaves like a 'Frequent Flyer.'"</p>
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vbWVkaWEucmJsLm1zL2ltYWdlP3U9JTJGbWVkaWElMkZFb0R2QmtYVzRBQThsbHouanBnJTNBbWVkaXVtJmhvPWh0dHBzJTNBJTJGJTJGcGJzLnR3aW1nLmNvbSZzPTE2MyZoPTE1NzMzNWNiNmNlMTdjZDJjODAxYTJlMWVlMzFlMWI3YTQ4MWQ3YWFlOTA1YzE0NWQwZWVlOTgxNDRjOWUyNzcmc2l6ZT05ODB4JmM9MTM5MjE2MDk0MSIsImV4cGlyZXNfYXQiOjE2MTUyNzQ3MzF9.w7gpcbinIUQ1CD4qc6dxKjSVdVMRRSuM3Ewtpn_OtvU/img.jpg" id="da326" class="rm-shortcode" data-rm-shortcode-id="8f24f0149444c92249de4a8988f61309" />Twitter
<p>But Kaavan's journey to Cambodia was much longer than the 10 hour flight. Kaavan, an Asian elephant, was first gifted to Pakistan from Sri Lanka in 1985 and found his first home at the Marghazar Zoo, according to Four Paws. From 1990 until 2012, he shared his enclosure with Saheli. But then she died after an infection turned gangrenous, <a href="https://apnews.com/article/pakistan-animals-elephants-islamabad-animal-welfare-4c002d8b04544388b065f0500ac9e306" target="_blank">The Associated Press reported</a>. Her body was left in the enclosure for several days after she passed away, Four Paws veterinarian Dr. Amir Khalil said Kaavan was heartbroken by the experience.</p><p>Even before Saheli's death, the Marghazar Zoo was not a pleasant place to live. Kaavan spent most of his 35 years there in chains. But his condition deteriorated after his partner passed away, and wildlife advocates dubbed him the "world's loneliest elephant."</p>
<p>Cher learned about his case on Twitter and decided to get involved, according to <a href="https://edition.cnn.com/travel/article/cher-pakistan-elephant-kaavan-intl-hnk-scli/index.html" target="_blank">CNN</a>.</p><p>"I thought, 'how can I fix this? How can I save an elephant who's been shackled to a shed for 17 years and who is a thousand miles away?'" Cher told CNN.</p><p>Kaavan's relocation to Cambodia marks the first big rescue for Free the Wild, which Cher co-founded. It is also the first time Four Paws has moved an elephant by plane, the organization said.</p><p>Khalil spent three months preparing Kaavan for the journey, The Associated Press reported. At the start of the process, Kaavan was both malnourished and overweight, and suffered from behavioral problems because of his time spent alone. He started shaking his head for hours, and his nails are cracked and overgrown because the flooring in his enclosure harmed his feet.</p>
<p>Khalil put Kaavan on a diet of fruit and vegetables and helped him to lose a ton before the flight. He also helped him to get more relaxed before the journey, which Kaavan undertook with only mild sedation, according to <a href="https://www.instagram.com/p/CIMBkLoAbjX/" rel="noopener noreferrer" target="_blank">Free the Wild</a>.</p><p>"Kaavan quickly gained confidence in us and made great progress in a short time. In his case it not only took a village but a whole country to transfer Kaavan to Cambodia," Khalil told Four Paws.</p><p>Cher was both in Pakistan to see Kaavan off and in Cambodia to greet him on his arrival. She sang "A Dream Is a Wish Your Heart Makes," to him before he left, according to CNN. In Pakistan, she also met with Pakistani Prime Minister Imran Khan on Friday, according to The Associated Press.</p><p>"Just Came From Meeting To Thank Prime Minister Imran Kahn For Making It Possible For Me To Take Kaavan To Cambodia," she <a href="https://twitter.com/cher/status/1332296298989580288" rel="noopener noreferrer" target="_blank">tweeted Friday</a>.</p><p>She also said that Kaavan's story would be told in a Smithsonian documentary.</p>
<div id="66bbe" class="rm-shortcode" data-rm-shortcode-id="b2be63265ec60d2bb78c8e758bee8144"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1332440451517845504" data-partner="rebelmouse"><div style="margin:1em 0">🐘Kaavan's journey to freedom from captivity in Islamabad to Cambodia will be a 2021 @SmithsonianChan documentary ❤️… https://t.co/zgESUUzD9x</div> — Cher (@Cher)<a href="https://twitter.com/cher/statuses/1332440451517845504">1606513533.0</a></blockquote></div>
<p>In Cambodia, Kaavan will live in the <a href="https://www.cambodiawildlifesanctuary.com/#:~:text=The%20Cambodia%20Wildlife%20Sanctuary%20was,and%20remarkable%20habitat%20of%20Cambodia.&text=The%20sanctuary%20is%20located%20in,covers%20approximately%20One%20million%20acres." target="_blank">Cambodia Wildlife Sanctuary</a>, where there are three other female elephants to keep him company, Four Paws spokesperson Martin Bauer told <a href="https://www.npr.org/2020/11/27/939509981/worlds-loneliest-elephant-moving-to-sanctuary-with-help-from-cher" target="_blank">NPR</a>.</p><p>"The goal is to socialize him," Bauer said. "It will take a while because he has lived on his own for such a long time. But yes, ultimately the goal is to bring him together with other animals because that's what elephants want. They're herd animals, they always form families, and that's also what we plan for him."</p>Kaavan is not the only animal who suffered at the Marghazar Zoo. The Islamabad High Court ordered its closure in May because of cruel conditions. Four Paws is also helping to relocate other zoo animals. It has found new homes for three wolves, some monkeys and all of the zoo's rabbits, the organization said. It will rehome two Himalayan brown bears in December. Margolis, the U.S. businessman, is helping to fund the rescue of the animals, including the bears, and paid for half of Kaavan's flight.

Climate change is causing leaves to change color and fall earlier in the year. Pxfuel
By Philip James
As the days shorten and temperatures drop in the northern hemisphere, leaves begin to turn. We can enjoy glorious autumnal colors while the leaves are still on the trees and, later, kicking through a red, brown and gold carpet when out walking.
<p>When temperatures rise again in spring, the growing season for trees resumes. Throughout the warmer months, trees take carbon dioxide from the atmosphere and store it in complex molecules, releasing oxygen as a byproduct. This, in a nutshell, is the process of photosynthesis. The more photosynthesis, the more carbon is locked away.</p><p>We know that carbon dioxide is a major driver of climate change, so the more that can be taken out of the atmosphere by plants, the better. With the warmer climate leading to a longer growing season, some researchers have <a href="https://www.fs.fed.us/nrs/pubs/jrnl/2014/nrs_2014_keenan_001.pdf" target="_blank">suggested</a> that more carbon dioxide would be absorbed by trees and other plants than in previous times. But <a href="https://science.sciencemag.org/cgi/doi/10.1126/science.abd8911" target="_blank" rel="noopener noreferrer">a new study</a> has turned this theory on its head and could have profound effects on how we adapt to climate change.</p>
Reaching the Limit
<p>The researchers, led by Deborah Zani at the Swiss Federal Institute of Technology, studied the degree to which the timing of color changes in autumn tree leaves was determined by the growth of the plant in the preceding spring and summer.</p><p>Temperature and day length were traditionally accepted as the main determinants of when leaves changed color and fell, leading <a href="http://max2.ese.u-psud.fr/publications/Delpierre_2009_AFM.pdf" target="_blank" rel="noopener noreferrer">some scientists</a> to assume that warming temperatures would delay this process until later in the season. Studying deciduous European tree species, including horse chestnut, silver birch and English oak, the authors of the new study recorded how much carbon each tree absorbed per season and how that ultimately affected when the leaves fell.</p><p>Using data from the <a href="https://www.researchgate.net/profile/Barbara_Templ/publication/323254030_Pan_European_Phenological_database_PEP725_a_single_point_of_access_for_European_data/links/5a8bf0dba6fdcc6b1a442ef2/Pan-European-Phenological-database-PEP725-a-single-point-of-access-for-European-data.pdf" target="_blank" rel="noopener noreferrer">Pan European Phenology Project</a>, which has tracked some trees for as long as 65 years, the researchers found in their long-term observational study that as the rate of photosynthesis increased, leaves changed color and fell earlier in the year. For every 10% increase in photosynthetic activity over the spring and summer growing season, trees shed their leaves, on average, eight days earlier.</p><p>Climate-controlled experiments on five-year-old European beech and Japanese meadowsweet trees suggest what could be behind this unexpected result. In these trials, the trees were exposed to full sun, half shade or full shade. The results show that there is a limit to the amount of photosynthesis that a tree can carry out over a growing season. Think of it like filling a bucket with water. It can be done slowly or quickly, but once the bucket is full, there is nowhere for any more water to go.</p><p>This research shows that deciduous trees can only absorb a set amount of carbon each year and once that limit is reached, no more can be absorbed. At that point, leaves begin to change color. This limit is set by the availability of nutrients, particularly nitrogen, and the physical structure of the plant itself, particularly the inner vessels which move water and dissolved nutrients around. Nitrogen is a key nutrient which plants need in order to grow, and it's often the amount of available nitrogen that limits total growth. This is why farmers and gardeners use nitrogen fertilizers, to overcome this limitation.</p><p>Together, these constraints mean that carbon uptake during the growing season is a self-regulating mechanism in <a href="https://www.pnas.org/content/111/20/7355" target="_blank">trees</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/31158300/" target="_blank" rel="noopener noreferrer">herbaceous plants</a>. Only so much carbon can be taken up.</p>
Earlier Autumn Colors
<p>In a world with increasing levels of <a href="https://public.wmo.int/en/media/press-release/carbon-dioxide-levels-continue-record-levels-despite-covid-19-lockdown#:%7E:text=The%20annual%20globally%20averaged%20level,per%20million%20benchmark%20in%202015." target="_blank" rel="noopener noreferrer">carbon in the atmosphere</a>, these new findings imply that warmer weather and longer growing seasons will not allow temperate deciduous trees to take up more carbon dioxide. The study's predictive model suggests that by 2100, when tree growing seasons are expected to be between 22 and 34 days longer, leaves will fall from trees between three and six days earlier than they do now.</p><p>This has significant implications for climate change modeling. If we accept that the amount of carbon taken up by deciduous trees in temperature countries like the UK will remain the same each year regardless of the growing season, carbon dioxide levels will rise more quickly than was previously expected. The only way to change this will be to increase the capacity of trees to absorb carbon.</p><p>Plants that aren't limited by the amount of nitrogen available may be able to grow for longer in the warming climate. These are the trees which can take nitrogen from the air, such as <a href="https://www.woodlandtrust.org.uk/trees-woods-and-wildlife/british-trees/a-z-of-british-trees/alder/" target="_blank">alder</a>. But these species will still lose their leaves at roughly the same time as always, thanks to less daylight and colder temperatures.</p><p>But on the upside, with the prospect of some trees losing their leaves earlier and others losing them at the time they do now, there might be the prospect of prolonged autumnal colors – and more time for us to kick through the leaves.</p>From Your Site Articles

Modoc County lies in the far northeast corner of California, and most of its 10,000 residents rely on cattle herding, logging, or government jobs for employment. Rodeos and 4-H programs fill most families' calendars; massive belt buckles, blue jeans, and cowboy hats are common attire. Modoc's niche brand of American individualism stems from a free-spirited cowboy culture that imbues the local ranching conflict with wild horses.
<p>To many, wild horses are icons of freedom and independence. While prevailing science says they are an invasive species that arrived with the Spanish conquistadors nearly a half-millennium ago, <a href="https://www.yesmagazine.org/environment/2020/04/27/native-horses-indigenous-history/" target="_blank">some say they are Indigenous to this continent</a>. Regardless of their origins, more than 95,000 wild horses are roaming across public lands in the West. The <a href="http://www.blm.gov/sites/blm.gov/files/WHB-Report-2020-NewCover-051920-508.pdf" rel="noopener noreferrer" target="_blank">population goal</a>, based on available forage and water, is closer to 27,000. With no effective natural predators, unmanaged populations can double in four to five years (and triple in six to eight years).</p>
<p>These growing numbers have instigated and intensified <a href="http://digitalcommons.usu.edu/cgi/viewcontent.cgi?article=1455&context=hwi" target="_blank">ecological and social challenges</a> in rural Western communities: Wild horses destroy fences, compete with cattle for grazing, alter native plant communities, affect wildlife behavior, and challenge watershed function.</p><p>They also cost the U.S. a lot of money. To manage wild horses, the Forest Service and the Bureau of Land Management have to cover both on-range populations and off-range holding costs. The estimated lifetime cost of keeping a wild horse in off-range pastures or holding facilities is $50,000 per animal. In 2019 alone, the bureau spent nearly $50 million caring for wild horses.</p>
<p>National wild horse advocates often love their equines from a distance; many are convinced that any sort of wild horse management is inhumane. But locals, including Native American populations, will tell you that they have struggled to coexist with the proliferation of horses for generations and that management is necessary. Ranchers insist that unchecked propagation of wild horses overruns the sagebrush landscape that their cattle graze on and share with various native and migratory animals and birds. At the same time, wild horse supporters push back against cattle ranchers' powerful economic interests.</p><p>Tensions over the management and allocation of resources in these regions run high. But solutions for assuaging these conflicts are already in play, including fertility control, roundups to adopt wild horses, and land acquisition. Long-term resolution will likely depend on a strategic combination of all three, along with a shared understanding among community members, public servants, and advocacy groups about what a healthy ecological balance looks like across the sagebrush landscape of the West.</p>
The History of Horse Management
<p>Before the 1950s, feral horses were largely unregulated in the U.S. They were released, grazed, captured, killed, sold, and otherwise <a href="http://www.blm.gov/sites/blm.gov/files/WHB-Report-2020-NewCover-051920-508.pdf" target="_blank" rel="noopener noreferrer">managed by local inhabitants</a> as they saw fit. Around that time, Velma Bronn Johnston, aka "Wild Horse Annie," started raising public awareness of the "perceived inhumane capture and treatment of free-ranging herds."</p><p>Thanks in part to Johnston's efforts, the Wild Free-Roaming Horses and Burros Act was signed into law by President Nixon in 1971. It declared that the animals "shall be protected from capture, branding, harassment, or death; and to accomplish this, they are to be considered in the area where presently found, as an integral part of the natural system of the public lands."</p><p><a href="http://science.sciencemag.org/content/341/6148/847.full" target="_blank" rel="noopener noreferrer">This act</a> has been amended four times since its conception to accommodate the fluctuating opinions and conditions around maintaining a "thriving natural ecological balance on the public lands"—an admirable although highly subjective goal. Achieving it involves juggling competing interests: those of local residents, permanent grazers, hunters and fishers, advocacy groups, conservationists, and Indigenous tribes.</p><p>The Bureau of Land Management must manage these many conflicting interests. Modoc County's <a href="https://www.fs.fed.us/wild-horse-burro/territories/DevilsGardenPlateau.shtml" target="_blank">Devil's Garden Plateau Wild Horse Territory</a> epitomizes the challenges of this task. Officially deemed wild horse territory, the garden consists of 258,000 acres and is wholly within permitted livestock allotments. It is also home to wildlife such as cougar, antelope, migratory birds, and aquatic species dependent on delicate high-desert riparian areas.</p><p>The presence of wild horses has been shown to <a href="https://www.sciencedirect.com/science/article/pii/S014019631530094X" target="_blank">decrease native wildlife species diversity</a> for both birds and mammals. Pronghorn antelope are an icon in Western grasslands, known for their annual 350-mile migration along historic routes estimated to be 5,800 years old. This awe-inspiring trek is one of the longest large-mammal migration corridors remaining in North America, but 75% of <a href="http://conbio.onlinelibrary.wiley.com/doi/abs/10.1111/j.1523-1739.2004.00548.x" target="_blank" rel="noopener noreferrer">pronghorn migration routes</a> have already been lost because of disturbances from the accelerated leasing of public lands and energy development. Horses also affect the pronghorn's yearly migrations by <a href="http://www.sciencedirect.com/science/article/pii/S014019631630218X" target="_blank" rel="noopener noreferrer">monopolizing watering holes</a>, thus preventing native species from drinking.</p>Indigenous Support for Ecological Balance
<p>Ken Sandusky, a public information officer who has worked for the Forest Service in Modoc County for 13 years, lives by his station's mission statement: "Caring for the Land and Serving People." In his work, Sandusky aims to include the broad range of stakeholders and often acts as a tribal liaison. Sandusky himself is a member of the Choctaw tribe of Oklahoma, but as a Modoc native, is more culturally in touch with the local Klamath tribe.</p><p>When it comes to rangeland health, he says, there's a tangible split in what that actually means. "It depends on what you are measuring the outcome against," Sandusky explains. Range managers may perceive progress from a year-to-year basis, but to many Indigenous tribes, the baseline for "progress" goes back generations, to pre-contact times. "They have long memories," he says. "Tribes see damage that is a hundred-plus years in the making."</p><p>While individual perspectives on wild horses may vary among cattle ranchers, as a whole, herders are in favor of stricter wild-horse management to lessen grazing competition for their livestock. Indigenous tribes in Modoc, too, are largely supportive of wild horse management. But they also challenge the sustainability of current cattle grazing management. Local tribes collect wild onions, wild roses, grasses for basketry, and wood for bows and arrows—materials that are incontrovertibly affected by unmanaged grazing, regardless of the species.</p><p>Still, Sandusky, along with other public servants at the Forest Service and the Bureau of Land Management, express concern about the dogma of wild horse advocates. "They tend to forget or intentionally ignore how they don't hold a monopoly over public opinion," he said. "Stakeholders can get myopic and good at keyhole storytelling."</p>
A Willingness to Try New Things
<p>"Americans don't know what's happening on these lands," says Suzanne Roy, the executive director of the American Wild Horse Campaign, an advocacy organization. The Bureau of Land Management, she says, "is run by and for the livestock industry. They come from a ranching background. The term 'rangeland' management itself illustrates how livestock management is the dominant perspective."</p><p>Roy is particularly concerned about how resources are being allocated: "Policies of land management agencies don't reflect the desires and interests of the public." To illustrate, most Americans associate public lands with national parks and environmental conservation; only 29% of respondents to a recent poll considered livestock grazing an acceptable use of those lands.</p><p>Grazing on public lands certainly aligns with the financial interests of cattle ranchers and helps explain why they insist on increased wild horse management. Cattle can <a href="http://fas.org/sgp/crs/misc/RS21232.pdf" target="_blank">graze on public lands</a> for $1.35 per animal per month, while grazing on comparable private land costs ranchers $23 per animal per month (American taxpayer dollars make up the difference). To be fair, though, small-scale ranching would not be viable without public lands.</p><p>The campaign hopes to work toward more equitable resource allocation and improvements to overall habitats for horses and wildlife generally. "There are workable solutions to this issue," Roy says. "Common pushback from rangers is that new conservation strategies will 'destroy our way of life,' but change doesn't have to be bad."</p><p>The <a href="https://www.sciencedirect.com/science/article/abs/pii/0362331994900264" target="_blank">social conservatism</a> intrinsic to human cultures makes change seem daunting and people reluctant to try new tactics even in the face of suboptimal systems. Roy uses a case in adjacent Marin County to illustrate: Until 2001, the county ran a USDA program focused on killing apex predators (e.g. coyotes, mountain lions, and cougars) in defense of livestock. Unfortunately, this strategy fails to take into account the science of predators. Killing one mountain lion, for example, creates a vacuum and will eventually lead to increased competition for this newly available territory. In 2001, Marin introduced a country-run program that promoted nonlethal methods such as fox lights, guard dogs, and fladry to deal with predator incidents while compensating ranchers for sheep and lambs lost to predation.</p><p>Ranchers were initially livid, concerned that bans on shooting and trapping hindered their rights, making them defenseless against livestock predation. But 15 years later, a majority agreed that this form of humane <a href="http://www.projectcoyote.org/wp-content/uploads/2016/10/Camilla-Fox-Thesis-FINAL-January-2008.pdf" target="_blank" rel="noopener noreferrer">adaptive management </a>has successfully reduced both livestock losses and the total number of predators. Ensuring its continued success, the program requires active participation on behalf of all stakeholders and long-term commitment from the local government for support.</p><p>As one fifth-generation sheepherder, Gowan Batiste, explained in an interview to the <a href="https://www.msn.com/en-us/news/us/mendocino-county-rancher-and-others-calling-for-non-lethal-wildlife-management/ar-BB16CJ8g" target="_blank" rel="noopener noreferrer">Ukiah Daily Journal,</a> "Livestock is a food of desperation for predators; the more you harass them and make life difficult for them, the more likely they are going to come into conflict with humans."</p>Keeping Wild Horses in Check
<p>When it comes to wild horses, many solutions are already in the works. Through annual autumn wild horse roundups, known as gathers, the Double Devil Wild Horse Corrals has become one of the U.S.'s most successful adoption sites. The California Cattlemen's Association, a nonprofit trade association and organization popular among ranchers in Modoc, urges its members to support the wild horse gathers in Devils Garden, saying they are humane, good for the horses themselves (since competition for scarce water and forage resources may instigate aggression and <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/j.1439-0310.1981.tb01930.x" target="_blank" rel="noopener noreferrer">herd violence</a>), and necessary to support local ranchers and Modoc's agriculture-reliant economy.</p><p>Another popular solution for controlling wild horse populations is a fertility-control vaccine called PZP, given to female horses on the range <a href="https://www.youtube.com/watch?v=Ur7w3UPTCsk" target="_blank" rel="noopener noreferrer">using dart guns</a>. Mares are tracked on foot or with game cameras while drones are used to locate more elusive herds. The PZP vaccine has been endorsed by the American Wild Horse Campaign as the "<a href="https://americanwildhorsecampaign.org/fertility-control" target="_blank" rel="noopener noreferrer">most promising strategy</a>" for managing wild horses in their habitats and is also recommended by the National Academy of Sciences. Importantly, a dose of the vaccine only costs $30.</p><p>Lastly, land acquisition and <a href="https://americanwildhorsecampaign.org/equitable-share-resources" target="_blank">grazing lease buyouts</a> can promote equitable sharing of public lands and available forage. Acquiring key pieces of land adjacent to or within federally designated wild horse habitat areas can reduce conflicts over resource allocation.</p>A Global Search for Solutions
<p>Pastoralists all over the world face similar land-use conflicts, despite huge variations in climate and culture. The ongoing situation across rural California resonates with that of Fulani cattle herders in Niger and Sami reindeer herders in the Arctic.</p><p>Herders everywhere are accused of having too many animals or are perceived as selfish and irresponsible by their own communities. Overgrazing is certainly an issue, but it's not simply the number of animals that matters: The <a href="https://savory.global/holistic-management/" target="_blank">amount of time</a> animals spend in a certain area is critical to rangeland health. And in the context of such allegations, the ecological value of grazing is frequently omitted. Grazers, both wild and domestic, <a href="https://www.yesmagazine.org/issue/food-everyone/2019/02/04/restoring-the-range-can-beef-be-earth-friendly/" target="_blank" rel="noopener noreferrer">are key to regulating soil health and allowing for species diversity and coverage, </a>as well as efficient carbon sequestration.</p><p>Part of the problem in these heated grazing debates is that moderate viewpoints are drowned out by extremist agendas—those who prioritize wild horse populations at all costs and those who want all of the horses gone, period. "The majority of people don't really have strong views about the horses," Sandusky says. "But the ones who do can get really into it." These unwavering views make it difficult to find compromises that account for all stakeholders.</p><p>"There is no biological problem, merely a social one," says professor Nicholas Tyler, a pastoralism expert at the University of Tromsø in northern Norway. Tyler maintains that in the case of horses and cattle in the West, as with so many others, the so-called equilibria argument is specious and quasi-biological. "Certainly a lot of horses will influence the species composition," he says. "Remove the horses, things change. Add horses, things change again. There is nothing magical about that."</p><p>But Tyler takes it one step further: "There never was, is, or will be a balance. There are shifting equilibria, which is something quite different," he says. "It is up to the community to decide which state of that equilibrium it prefers."</p><p>Regardless of one's views on what the ideal or preferred proportion of horses, cattle, and wildlife should be, holistic strategies could lead to increased cooperation and knowledge exchange as part of mitigating the current tension. One study examining the mutual dependence of extensive land-use and conservation management in Eastern Europe makes the case for a new profession: the "<a href="http://esajournals.onlinelibrary.wiley.com/doi/pdf/10.1002/ehs2.1215" target="_blank">conservation herder</a>."</p><p>This idea combines age-old <a href="https://www.youtube.com/watch?v=2Dq_U-yCBfI" target="_blank">traditional herding knowledge</a> with a newfound awareness of herders' role in providing ecosystem services. Conservation herding could support pastoralists through the continued sale of their meat and milk production as well as government subsidies for biodiversity management.</p><p>Refreshing pasture management techniques and adapting traditional herding strategies to current rangeland vegetation conditions will provide the necessary backdrop for such solutions to take. Perhaps most importantly, reconciliation of a livelihood that has been traditionally judged as anterior to conservation causes may be exactly what a place such as Modoc needs to move forward. As a society, we tend to not address issues if there are no easy answers or if they cannot be solved by the next news or election cycle. Sandusky says: "Some of us don't have that choice."</p><p><em>Kang-Chun Cheng is a freelance environmental photojournalist based in Nairobi, Kenya. Her background in ecology, with a focus on community-based natural resource management and traditional knowledge, informs and enhances her perspectives as a photojournalist. She is fascinated by the shifting dynamics and values between society, culture, and nature, and use photography as a tool for storytelling. She has been documenting the impact of technology and climate change on traditional reindeer herding culture in Norway and Finland since 2017. She loves rock-climbing, cooking, and knitting. Her work has previously been published in Earth Island Journal, the Valley News, Northern Woodlands, China Africa Project, and others.</em></p><p><em>Reposted with permission from <a href="https://www.yesmagazine.org/environment/2020/11/27/wild-horses-west-land-management/" target="_blank">YES!
