Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsored 123456789101112131415161718192021222324252627282930313233343536

In March 2016, Camilo Mora and colleagues published a report on military base building across the Spratlys. In the same month, I was working on the northern tip of Borneo, east of the Spratlys, and I decided to expand our mapping efforts into the archipelago. I wanted to better understand what is being lost with each military base conversion of a Spratly atoll. By May 2016, I got a chance to visit one of the atolls in the southeast corner of the archipelago.Known as Swallow Reef, or Pulau Layang Layang by the Malaysian government that administers it, the atoll is an amoeba-shaped ring of reef that drops off more than 3000 meters into deep ocean (Fig 2). In one corner of the atoll lies a small Royal Malaysian navy outpost, manned with a few patrol vessels. Alongside the outpost is a place where diehard divers can spend time exploring some of the most unique and endangered coral reef ecosystems on Earth. Moving down in the water column at Swallow Reef is like slicing through a psychedelic layer cake that would impress Willy Wonka lovers. The outer reef is replete with millions and millions of colorful specks of life, hard and soft corals, schools of jacks, batfish, barracuda, and more, each contributing to an ecosystem patrolled by giant mantas and sharks. Picture what you think a perfect coral reef ecosystem might look like, well before the global degradation of reefs that started with the industrial revolution, and that will put you at Swallow Reef.Figure 2: Swallow Reef atoll is administered by the Malaysian government, and houses a small navy base and diving facility.

A view of the atoll from the runway on Swallow Reef, as a tropical storm approaches in 2016 (bottom image)My initial visit to Swallow Reef yielded thousands of photographs and video. It also sparked the idea to combine rapid underwater surveys with a new class of satellite imaging that might give us a fast-track way to assess coral reefs on more atolls than we could possibly visit in the water. To do this, I turned to my colleagues at Planet.com, formerly known as Planet Labs. They operate the world’s largest constellation of small orbiting satellites that can image Earth on a daily basis at about 3 to 5 meter spatial resolution. As one of Planet’s science Ambassadors, I collaborate with the company to apply their satellite data to new environmental challenges, so the Spratlys were a perfect fit.Planet’s constellation of ‘Dove’ satellites can give us a daily viewing of the South China Sea, which is critical since the region is naturally very cloudy. By selecting cloud-free images that were available shortly before and after my initial visit to Swallow Reef, my collaborators Robin Martin from Carnegie, Joe Mascaro from Planet, and I were able to align the satellite images with our near-realtime understanding of reef composition and condition. Martin and I returned to Swallow Reef in July to complete an intensive series of additional underwater surveys, which when combined with the Planet Dove data in the field, helped us to determine that we can easily map the extent of coral reef. We were also able to map some of the deeper reefs. Our overall mapping accuracy ultimately exceeded 90 percent.From the Swallow Reef pilot study, we extended the mapping approach to all of the atolls currently occupied by China, Malaysia, Philippines, and Vietnam – the four countries most present throughout the region. We compared the proportion of coral reef on occupied atolls to unoccupied ones, and found up to 70 percent reduction in coral reef cover on those with military bases (Asner et al. 2017). In other words, military base and outpost building has destroyed huge expanses of coral reef, which means that millions of its colorful lifeforms have been wiped off the planet.Figure 3. Proportion of shallow coral reef cover on unoccupied versus occupied atolls in the Spratly Islands, South China Sea, organized by current occupying nation.Shockingly, the vast majority of this loss has taken place in just the past three years. Yet promising is the fact that there are still a hundred or so reefs with relatively little human impact, so conservation and management ought to have a chance to make a difference before it is too late. Also promising is the fact that recent coral bleaching events do not seem to have had as large an impact in the South China Sea as we have seen on the Great Barrier Reef. I experienced very little bleaching during our survey dives at Swallow Reef. As Professor John McManus, University of Miami, has long emphasized based on his work in the region, a promising pathway forward to protecting the remaining coral reefs of the South China Sea rests in the development of an international peace park agreement between nations. Based on our recent experience with Planet Dove satellites and diving, time is of the essence to get a park-style accord accomplished.School of barracuda on a Spratly Island atoll.

Seeing a submarine at sea with a scuba tank on your back is like pricking yourself on a needle lost in a very big haystack. But the South China Sea is not your average haystack, and nothing seems to be lost out in its vast expanse.The South China Sea stretches from the coast of mainland China to the shores of Borneo, Vietnam, and Philippines. The southern part is a huge blue water world dotted with remote atolls and islands known as the Spratly Islands, named after whaler Richard Spratly who ‘discovered’ them in 1843. The Spratlys have many other names in the languages of nations that encircle the South China Sea, an expression of the long-standing strain between multiple claimants of the region. Brunei, Malaysia, Philippines, and Vietnam each claim a portion of the Spratly archipelago, and China claims all of it.Figure 1: The Spratly Islands are located in the southern portion of the South China Sea.The region has also become a hotbed for modern naval activity, owing to critical commercial shipping through its waters, and the oil that underlies its seabed. The U.S. routinely navigates the South China Sea as a demonstration of its naval power, said to ensure right-of-passage, and which China openly views as a threat. And as a result, military base and outpost building continues at a feverish and ecologically destructive pace. Whole coral reef atolls have been dredged to form hard land for military complexes and aircraft runways.As a global ecologist and conservation scientist, I have long been interested in the Spratlys as a biodiversity hotspot. With its purported 600 coral and 6000 fish species, I had wondered what this ecoregion looks like underwater, and more recently, what the frenzied building of military bases might mean for its sea life. I wondered too if coral reefs of the Spratlys had been impacted by recent hot water events that cause coral bleaching, like that which has devastated the Great Barrier Reef.There isn’t nearly enough scientific literature on the ecology of the Spratlys, but it has been shown that the atolls are important sources of coral larvae for that part of the South China Sea. Each atoll is a habitat for connected layers of lifeforms ranging from corals and invertebrates to huge schools of hammerhead sharks and bottlenose dolphins. Each layer relies on the presence and health of the next layer, and the coral reefs form a critical core for the regional ecosystem as a wholelast_img
