first_imgLong-term declines in rainfall on the Big Island of Hawaii have added up over time to make forests shorter and less green.Data from satellites and airplane surveys showed that forest canopy greenness decreased twice as much in areas where annual rainfall had steadily declined since 1920.Long-term drying trends in other parts of the world may have far-reaching impacts on forests. A plant without water will wither and, eventually, die. This is easy to observe in the browned leaves of a neglected houseplant, but what happens when an entire forest gets less and less rain over the course of nearly 100 years?To address this question, researchers used satellites and a high-tech airplane to spy on the native forests of Hawaii’s Big Island. The effects of drought do not end when rains return, the study showed. Rather, these impacts add up over time to make forests shorter, less dense, and less green.Unprecedented droughts and large-scale decreases in average rainfall are affecting many locations around the world, climate data has shown. Scientists have long wanted to know how these changes will affect tropical forests. But such projects require high-quality weather data that spans decades, and it is difficult to make precise observations for vast swaths of forest.The Carnegie Airborne Observatory used a laser tool called LiDAR to detect the three-dimensional structure of the forests and terrain below the canopy. Photo courtesy of Gregory Asner/Carnegie Institution for ScienceEcologists Jomar Barbosa and Gregory Asner from the Carnegie Institution for Science at Stanford University met these challenges by using recent advances in remote-sensing technology. They also used a unique, long-term weather dataset on Hawaii’s Big Island, where rainfall has declined on one side of the island for the last century—affecting the native forests that grow on the volcanic slopes.For their study, the researchers used data from the Carnegie Airborne Observatory (CAO)—an airplane designed by Asner to study ecosystems at this scale. The plane carries nearly a metric ton of computing and remote-sensing technology.“Work on the ground is very hard to translate into the big picture,” said Asner in an interview. “The airborne observatory was conceived to try to draw out the major findings derived from all these different landscapes.”Changes in forest photosynthesis on Hawaii’s Big Island from 2002 to 2016. Red: decrease in photosynthesis. Green: increase in photosynthesis. White: other land-cover classes such as bare soil, invasive species, or human settlements. Graphic from Barbosa and Asner, Environmental Research Letters (2017).The study also used data from NASA’s Terra satellite, which tracked the greenness of forest canopies on the Big Island between 2002 and 2016. Greenness reflects how much photosynthesis is taking place. Less photosynthesis reflects a decline in plant growth—which means the forest can’t support as much life.The CAO flew over two patches of the Hawaiian forest in 2007 and 2016. One patch was on the island’s wetter side, and the second was on the island’s drier side. A laser instrument fired 400,000 pulses per second to measure the canopy’s height in detail. Taller trees typically contain more biomass, pointing to more sustained growth over time.Waipio Valley on the Big Island of Hawaii. Photo by Eric Tessmer/Creative CommonsTo connect the changes seen in canopy height and greenness to rainfall, the team used data developed by researchers at the University of Hawaii to trace the island’s rainfall by year and by location from 1920 to 2012. This allowed Barbosa and Asner to pinpoint the driest spots on the island at various time scales.They found that forests which had seen less and less rain since 1920 were shorter and two times less green than they would have expected from the effects of short-term droughts alone. Browned leaves and dying vegetation are common during extended droughts. But these results show for the first time that when rainfall declines over much longer time scales, the damages to forests pile up.“They were able to distinguish the loss of greenness from short-term versus long-term drying trends,” said Christian Giardina, a Hawaii-based ecologist with the U.S. Forest Service who was not involved in the study. “This kind of analysis highlights the importance of long-term climate data and paves the way for future studies that seek to integrate short-term and long-term datasets where they are available,” Giardina told Mongabay.Applying this work to managing important forests may be easier said than done, Asner said. “It’s time for land managers and policymakers to consider alleviating some of the other stresses on forests, like fire or invasive species,” he said. “Then you’re giving the forest a better chance of surviving this long-term decrease in precipitation. When I say this in meetings people know it’s the answer, but it’s hard to get it done.”The I’iwi or scarlet honeycreeper, a native Hawaiian forest bird.

Agriculture, forestry, and other land uses are responsible for nearly a quarter of all man-made greenhouse gas emissions. But forests are also one of our planet’s biggest carbon sinks and can contribute to carbon removal, thus constituting a key piece of the land and climate puzzle.The report provides a comprehensive look at the forest-related solutions we have, among other land-based responses, that could help us mitigate and adapt to climate change and the possible synergies and trade-offs with other critical land-related issues, including land degradation and desertification and food security.We now need the political will and action from governments, the private sector, and consumers to change the way society values forests, to stimulate forest protection, and to embrace sustainable forest management and forest restoration while reversing the pressure on forests. And we need to do so without displacing that pressure to other ecosystems.This post is a commentary. The views expressed are those of the author, not necessarily Mongabay. The vital contribution of forests in protecting biodiversity, regulating the climate, and enhancing human well-being is being recognized as never before.Forest-related responses to tackling the climate crisis are increasingly being seen as a cost-effective option among nature-based solutions. By protecting existing forests and halting deforestation, we can maintain some of our most important carbon sinks, and by restoring forests we can remove significant quantities of carbon dioxide from the atmosphere.There is, however, a vast gap between these solutions and reality. Climate change is placing additional stress on forests, and climate change impacts, compounded by trends such as consumption growth, infrastructure expansion, and increased food production, will put additional pressures on land. We are seeing this unfold at this moment in Russia, where record levels of forest fires have sparked fears about an ecological disaster. Or in Guatemala, where rapid deforestation has led to floods and water shortages.On August 8, scientists contributing to the Intergovernmental Panel on Climate Change (IPCC) published a new report examining the interactions between climate change and land use. Agriculture, forestry, and other land uses are responsible for nearly a quarter of all man-made greenhouse gas emissions. But forests are also one of our planet’s biggest carbon sinks and can contribute to carbon removal, thus constituting a key piece of the land and climate puzzle.Cane fires burning, Mount Inkerman, Queensland, Australia.

The report provides a comprehensive look at the forest-related solutions we have, among other land-based responses, that could help us mitigate and adapt to climate change and the possible synergies and trade-offs with other critical land-related issues, including land degradation and desertification and food security.We now need the political will and action from governments, the private sector, and consumers to change the way society values forests, to stimulate forest protection, and to embrace sustainable forest management and forest restoration while reversing the pressure on forests. And we need to do so without displacing that pressure to other ecosystems.Our call to action is challenging, but not impossible. Forest-related solutions are cost effective precisely because we can harness the power of nature to address climate change. But it also requires a fundamental shift in behaviors — in the way we use land for agriculture and in the way people consume and eat.The Special Report arrives shortly before the UN General Assembly and the Climate Summit in September, and the UN climate talks in December. It is a critical moment to reflect on responses related to forests and assess how they can be incorporated into national agendas and climate action plans of both developing and industrialized countries.Tractors for conversion of grasslands into crops, north of Pierre, South Dakota. Photo Credit: © Day’s Edge / WWF-US.Focus on forestsMost of the pressures on forests come from outside forests and the forestry sector — whether that’s demand for land to grow food, or because of policies and financial systems that don’t take account of the full value of forests. Effective forest protection, then, needs to originate outside forests, too — through improving land management, transforming food systems, and advancing more responsible finance and investment. And it needs to adapt to specific contexts to ensure the most cost-effective options for mitigation and adaptation to climate change, while ensuring synergies with land restoration and food security.Forests play a key role in the integrated response options that contribute to pathways limiting global warming to 1.5o degrees Celsius. Some of the forest-related solutions have clear win-wins, in the context of a broad range of land-based options. These include forest conservation, sustainable forest management, reducing deforestation and forest degradation, and agroforestry, given their co-benefits for mitigation, adaptation, reversing land degradation and food security.Expanding tree cover through reforestation and afforestation is expected to have positive benefits for mitigation and adaption and reversing land degradation, but there needs to be a concerted to avoid negative impacts on food security when deployed at a large-scale, as well as social and environmental impacts. Small-scale deployment with the use of best practices in managed landscapes under strong governance could bring some greater co-benefits. And these risks and benefits will require careful assessment depending on the context.Amoron’i Onilahy is a Protected Area managed by local communities who work to protect their natural wealth through ecotourism and the promotion of biodiversity.

Photo Credit: © Martina Lippuner / WWF-Africa.In addition, the potential of forest and ecosystems restoration, while not fully analyzed in the report, has taken center stage recently. For example, a recent study, based on different type of assumptions, has shown the technical potential for tree restoration to be as high as 900 million hectares (about 2.2 billion acres), though it is important to note that there is a large gap between the technical potential and the actual feasibility, and several barriers will have to be overcome. Another recent study found that the world’s largest carbon sinks are located in young forests regrown on former agricultural or deforested areas.The IPCC Special Report synthesizes our scientific knowledge about the potential of different forest-related responses in the context of integrated response options. But as critical as it is to take stock of our current knowledge, it is just as important to translate this knowledge into action, and actions to protect and restore forests will depend on collaboration between many actors — governments, donors, local communities, farmers, and the private sector.These actions have the potential to deliver significant benefits under approaches to manage whole landscapes or jurisdictions in a sustainable way. And these approaches require meaningful partnerships between governments, investors, and private companies with the close involvement of local farmers and communities.It is now time to scale this up and put science into action.Deforestation for future agriculture plantation in Tahuamanu Province, heading to Centro Poblado de Alerta, Madre de Dios Region, Peru.

first_img28 May 2012South African and international police are working together to curb a suspected international drug smuggling unit following the seizure of 1.1 tons of narcotics with a street value of R36-million in Tulisa Park outside Johannesburg on Saturday.The seizure was made during a joint operation between elite police unit the Hawks, the South African Police Service (SAPS) Crime Intelligence, and customs officials from the South African Revenue Service.The narcotics were packaged in fraudulently labelled packs, including pet food cans, tobacco and coffee packages, said national police spokesperson Captain Dennis Adriao.It is believed that the consignment of drugs was destined for international markets.Initial tests conducted at the scene indicated that the drugs were hashish.“The success of this seizure was attributed to information received from a member of the public and weeks of investigations, which identified the storage facility where the narcotics were being stored,” Adriao said.“The storage facility … was part of a freight service that stores consignments and then also dispatches the freight to various parts of the country and overseas.”Police also found a large tortoise, which was identified by the NSPCA Wildlife Unit as a leopard tortoise – an approximately 50-year-old female.“The tortoise didn’t have any food or water and was being kept together with the narcotics consignment. We believe that the tortoise could have been destined for the international markets as well, especially the Asian countries.”No arrests have been made as yet, but the Hawks were still following up on information, Adriao said.Source: BuaNewslast_img read more

first_imgIf you look at the new maps today, the most obvious changes are better data for park boundaries and the trails and paths that now appear prominently on the maps. In addition, if you see a mistake on a map (a bike trail that is marked as a road, for example), you can simply right-click on the road and the drop-down menu will now include the option to report a problem (there is also a link at the bottom of the map). Sadly, this feature doesn’t allow users to redraw maps themselves. Instead, you can only leave a short text comment. Other mapping projects like OpenStreetMap allow users to quickly redraw the lines themselves, though at the cost of increased complexity and a high learning curve. For now, Google promises to resolve each edit within a month.All of this additional data also adds a new layer of clutter to the maps, though. For now, it is not possible to turn the information about trails and paths on or off, for example. If you are planning a route to drive with your car, you probably won’t care much about the bike trails. At the same time, if you are planning a bike trip, it would be nice if you could just highlight all the biking trails in a given area.Focus on Better Maps Instead of More Satellite ImagesThe competition between online map providers has mostly been around adding new and higher-resolution satellite images lately. The Bing Maps July update, for example, came in at over 41TB of new satellite imagery and aerial photography. Now, it looks like Google is going back to pushing the envelope by focusing back on the straightforward mapping features that make up the core of every good mapping service. Top Reasons to Go With Managed WordPress Hosting Google just announced a major update to Google Maps in the United States. The new version not only includes better maps based on data from government organizations like the Forest Service and the US Geological Survey, but it also allows users to easily report problems with a map. In addition, Google Maps now features better maps for parks and water bodies, as well as college campuses. Trails and paths now also appear on the maps and thanks to this, Google plans to add biking directions to its routing feature in the near future. 8 Best WordPress Hosting Solutions on the Market Related Posts Tags:#news#web frederic lardinois Why Tech Companies Need Simpler Terms of Servic… A Web Developer’s New Best Friend is the AI Wai…last_img read more

first_imgThis week, an IBM supercomputer dubbed Watson took on Jeopardy champions Ken Jennings and Brad Rutter in a competition, pitting natural language processing and machine learning versus two Jeopardy champions. The three-day tournament ended on Wednesday with Watson soundly whooping its competitors. Now that it’s over you might wonder how it was done. What problems did the team behind Watson run into along the way? What’s next?If you head on over to social bookmarking site Reddit, you can ask them yourself. The site has gotten the IBM research team behind Watson to agree to hold a Q&A with Redditors and is fielding questions for the next several days.The Q&A is being held in the IAmA subreddit, where users of the site often offer themselves up to the community to field questions about whatever they feel others might be interested in. (A “subreddit”, by the way, is a user-created subsection of Reddit that caters to a particular topic.) “IAmA” is a shortened way of saying “I am a…” and can also be interchanged with “AMA,” which stands for “ask me anything.” The IAmA subreddit is full of user-created interviews other Redditors, celebrities, academics, scientists and more.Currently, users can submit questions to the topic. Over the next several days, users will be able to vote on these questions and the IBM Research Team will answer them on Tuesday, Feburary 22 at noon EST.Reddit co-founder Alexis Ohanian wrote today about what he thinks makes Reddit as successful as it is (it recently broke 1 billion monthly pageviews), pointing to the IAmA subreddit. IAmA “is an endless treasure trove of fabulous content being created within reddit,” wrote Ohanian. To take part in the Q&A, simply head on over, sign up for a free account if you don’t have one, and fire away.  Oh, and currently, the number one question? “Can we have Watson itself/himself do an AMA?” The answer? “We’re working on it ;)” Tags:#news#web Top Reasons to Go With Managed WordPress Hosting Related Posts mike melansoncenter_img Why Tech Companies Need Simpler Terms of Servic… A Web Developer’s New Best Friend is the AI Wai… 8 Best WordPress Hosting Solutions on the Marketlast_img read more

first_imgA very active passive house in the exhibit hallConferences are sometimes maddeningly similar: a big exhibit hall with too many booths and endless one-hour overview seminars.I didn’t see too many new things in the exhibit hall. (See Alex Wilson’s post to learn about new and exciting products.) One corner of the hall was populated by a row of Passivhaus product suppliers — interesting, since the movement is still quite small. RELATED ARTICLES It was nice to see super-high performance ERVs and flashing systems becoming more available here, although I rarely see any opportunities to incorporate these in my work as a consultant. As I pointed out in my last post, I struggle to make my client’s build buildings only slightly less crappy than they would otherwise. Being involved with true high-performance buildings is still a dream for me. After missing GreenBuild 2011 in Toronto, I was excited to be back this year in San Francisco, a city I visit so frequently that I consider it my second home. GreenBuild is a big conference, with attendence in the range of 30,000, down slightly from a few years ago, but still very impressive. It was held in the Moscone Center, well located in downtown San Francisco.Even though the Moscone Center has three separate buildings, the amount of walking is comparable to the monster halls in Las Vegas, Orlando, and Chicago, and when the weather is nice, it provides an opportunity to get outside. Networking is where it’s atAlthough I was disappointed with the education and the exhibit hall, as always, GreenBuild does offer excellent networking opportunities. I reconnected with old friends and associates, met new people, and made some good connections for future opportunities.As always, some people will love it and be inspired, especially those who have not been before. Some people will be lucky and pick sessions that are interesting and engaging.A few (or many) like me will be disappointed with most of what they see and long for more depth.center_img A Few Product Highlights from GreenBuild 2012 GreenBuild 2011 Opens in TorontoGreenbuild 2010 RecapGreenbuild 2009 Wrap-Up Education still lackingAs is often the case, the educational component was a mixed bag. I made the mistake of going to several sessions with interesting content, but, unfortunately, most of the speakers were not very engaging.Where the speakers were good, they lacked enough time for any depth of content. In my opinion, 15 to 20 minutes per person barely leaves time to introduce a subject. GreenBuild education tends to be a combination of motivational talks, high-level introductions, and a few self-serving sales pitches. I believe the conference would be better served by adding one- to two-hour in-depth sessions with single, excellent, speakers providing advanced instruction. I know that there were some excellent sessions, but apparently I missed most of them this year.While the facilities were nice, they conference room ceilings were frighteningly tall, creating a cavernous feeling. Some rooms were set up with a central elevated runway, video monitors, and high-end lighting. This setup was a nice change from the typical dais-at-the-end-of-the-room arrangement, but it seemed a little forced, and I couldn’t help thinking about how much all the equipment cost.last_img read more

first_imgGurugram: Having already achieved the dubious tag of being one of the most unsafe spots in the city, Kherki Dhaula toll plaza witnessed another showdown on Thursday morning.The woman toll collector rejected a driver’s identification card when he was trying to pass through the toll without paying any tax. She insisted that he pay the requisite amount of Rs 65 which is a one-time payment fee. The driver, named Rahul Yadav (26), travelling in a Maruti Alto with his friend, then slapped the woman collector before fleeing the spot, only to be arrested later. The incident occurred at around 11:50 am when the accused, a resident of Shikohpur, was stopped by the woman operator for the payment.

Before the matter escalated, the driver fled the spot. He was arrested two hours later and was charged under Sections 323 (punishment for causing voluntary hurt), 294 (obscenity) and 506 (punishment for criminal intimidation) of the IPC. “It is unfortunate that this incident occurred. However, we acted quickly and arrested the accused. He does not have a criminal record,” said a senior police official from Gurugram police.

A year-and-a-half after the idea to rope in women collectors was implemented; it seems to be falling apart now as unruly drivers do not even blink twice before being violent with those women. Toll attendants highlight that often the customers who are not willing to pay the amount argue with the toll booth attendants in order to intimidate them. Further, the ire of the local commuters who accuse the toll booth attendants of harassing them is another concern. “A major problem is being faced in dealing with the locals. As per rules, we are not allowed to charge them. However, they have to show a proper identity. As most of the people do not carry proper identity cards, the fact that we ask them to pay makes them angry and they start abusing us or in some cases, even physically assault us,” said a toll booth attendant on condition of anonymity.last_img read more
