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 Article published by John Cannon Four conservationists arrested for suspected espionage in Iran in January face charges of “sowing corruption on Earth.”The charges stem from the team’s use of camera traps to track the Asiatic cheetah, but Iran’s Revolutionary Guard contends that the accused were collecting information on the country’s missile program.If convicted, the conservationists could be sentenced to death. Up to five conservation researchers accused of spying by the Iranian government could face the death penalty if convicted, according to multiple media reports.Conservationists Niloufar Bayani, Taher Ghadirian, Houman Jowkar, Sepideh Kashani and Morad Tahbaz work with the Persian Wildlife Heritage Foundation on the conservation of different wildlife species in Iran, which includes monitoring animals such as Asiatic cheetahs (Acinonyx jubatus venaticus) with camera traps. The country’s Islamic Revolutionary Guard Corps, which reports to the country’s supreme leader, alleges that the team used camera traps to collect information on Iran’s missile program, Science magazine reported Oct. 30.The eight environmentalists from the Persian Wildlife Heritage Foundation currently being held in Iran on charges related to espionage. Image © #anyhopefornature.The five are among a group of eight — which also includes Amir Hossein Khaleghi, Abdolreza Kouhpayeh and Sam Rajabi from the same organization — being held in custody, according to The Guardian newspaper and other media reports. A sociologist and manager of the Persian Wildlife Heritage Foundation, Kavous Seyed Emami, who was arrested in early 2018, died under suspicious circumstances in February while in custody, observers said according to a report in The New York Times.“This is a very bizarre charge to bring against environmental activists,” Tara Sepehri Far, a researcher with Human Rights Watch (HRW), told Science.After months of confinement, five of the eight conservationists were charged with the crime of “sowing corruption on Earth” in early October, The Guardian wrote. (Science reported that only four of them — Bayani, Ghadirian, Jowkar and Tahbaz — were charged with the capital offense.)“Nine months of pre-trial detention with no clear charges and no access to a lawyer is an unusually long time even by Iran’s dismal due process standards. It’s hard not to conclude that the authorities are struggling to gather enough evidence to charge them with any recognizable crime,” Sepehri Far wrote in a post for the Atlantic Council, a think tank, before the revelation of the charges.The Asiatic cheetah, likely numbering fewer than 50 individuals, is found only in Iran. Image by Tasnim News Agency via Wikimedia Commons (CC 4.0).She said an investigation at the behest of Iranian President Hassan Rouhani did not find that the accused environmentalists were spies, which put them at the center of a “domestic power struggle” with hard-liners in the judiciary and the Revolutionary Guard.If convicted, the environmentalists could face sentences ranging from six months up to the death penalty.“It is hard to fathom how working to preserve the Iranian flora and fauna can possibly be linked to conducting espionage against Iranian interests,” a group of experts calling on the Iranian government to have the charges dropped said in a statement from the United Nations Office of the High Commissioner for Human Rights.Jon Paul Rodríguez, a biologist at the Venezuelan Institute for Scientific Research and chair of IUCN Species Survival Commission, highlighted the value of the work that the researchers had been doing.“As far as I am aware, practically the only information we have on the Asiatic cheetah comes from camera traps,” he said.Asiatic cheetahs likely number fewer than 50 individuals, based on a 2017 study co-authored by Jowkar, one of the people charged in this case, and the IUCN has considered the subspecies critically endangered since 1996.Because cheetahs live at low densities, the traps represent a much more efficient and economical tool to get an accurate picture of their population. In Botswana in southern Africa, scientists have used camera traps to demonstrate to ranchers that a cheetah on their property isn’t as dangerous to their livestock as they might think.An Asiatic cheetah in Miandasht Wildlife Refuge in Iran.

Engelberg (Switzerland): Indian badminton star Sai Praneeth, who enjoyed his best career ranking (15th) in 2017, has praised the Badminton Association of India (BAI) for supporting players and doing a lot of positive things to promote the game at the grassroots level. “Indian badminton association is on the right path, it is doing good things to promote the game at the grassroots and is continuously supporting the players and taking care of all their needs. “As a badminton loving nation, we are heading towards becoming a real powerhouse and the efforts should be continued because there are a lot of young players coming forth with immense talent and they should be rightly protected. The day is not far when we would win Gold in World championships,” the 2010 BWF World Junior Championships bronze medallist said. Praneeth believes that nowadays youngsters are posing a real challenge to the senior players and due to their strong presence it’s really difficult for the seniors to win even the nationals. Praneeth and Parupalli Kashyap, along with several other Indian players, are here to participate in the Swiss open 2019. They also visited Mount Titlis to promote the upcoming BWF World Championships to be held in Switzerland in June for the second time after a gap of 20 years. They played an exhibition match at 10,000 feet. The match was organised by the Swiss badminton association and the Mount Titlis Cable Car Company based in Engelberg. After the match, they took part in the press briefing of the Swiss badminton association to talk about the preparations for the World Championships. Praneeth said nowadays young Indian players are posing challenges to the seniors and it’s really difficult to beat them because they are well prepared and focused and their fitness level is at par with some of the international players. “I think the national championships are really difficult to win these days because there are so many players including some juniors who are really doing well. Overall badminton in India has grown up and it’s good that the youngsters are coming and posing challenges to the seniors. It’s a good thing for Indian badminton,” the Andhra Pradesh player said. Asked about the match at Mount Titlis, Praneeth remarked: “It’s entirely an amazing experience. I never thought of playing a match at such a height. And Mount Titlis is amazing, completely out of world thing for me. I really enjoyed being here and I really want to thank the Swiss badminton association for bringing us at such a wonderful place. “I really wish the upcoming World Championship a grand success and wish to win a medal there in Basel.” Talking about his personal game Praneeth said that he is working hard to overcome his shortcomings and increase his fitness level. “This season has just begun and I played in All England Open. I lost there and I am not happy with my performance over there. I am working on my shortcomings which reflected during the tournament. “I am especially taking care of my fitness because last year, I really struggled with my body. This year is very important for us and that’s why I have certain plans to improve my game and I am working hard towards them,” he said.

House No. 140, Motijheel police station building at Motijheel commercial area.A plot drawn up by vested quarters to occupy four state-owned houses in the capital, has been foiled.A Pakistani citizen was brought to Bangladesh so he could take over as the owner of these houses. He was speedily issued a birth certificate and passport to facilitate his taking possession of the property.Vice chairman of Beximco Group Salman F Rahman aided and abetted the Pakistani citizen Waqar Ahmed in this dubious plan.One of the houses is Sada Bahar, House No. 104, Road No. 3, Dhanmondi. The house is being now used as the training office of the National Security Intelligence (NSI). Another is house No. 140, the Motijheel police station building.Two others are houses are No. 10, Motijheel and No. 64, Dilkusha. These two houses are leased out to five persons including the owner of Bangladesh Typewriter Mahbubur Rahman and late state minister Ziaul Haque Zia. There are commercial establishments in these two buildings. The buildings are owned by the housing and public works ministry.A bench of justice Mohammed Nuruzzaman and justice SH Mohammed Nurul Huda Jaigirdar passed an order in this regard on 13 April.Speaking to Prothom Alo, assistant attorney general Sukumar Biswas said the papers, which were submitted claiming the ownership of these four houses, were forged. Through the verdict it has been established that no one can claim these houses. These are now abandoned property. These houses were under the control of the government and the government is still the owner of these four houses.In a written statement to Prothom Alo, Beximco Group vice chairman Salman F Rahman denied that fake documents were used to take over the houses illegally.The power of attorney was legally taken. The claimant of these houses Waqar Ahmeds son Gulzar Ahmed was a classmate of Salman F Rahman at Notre Dame College. Gulzar met Salman F Rahman in London recently and asked for his assistance. Salman F Rahman took up legal procedures to help with Gulzar Ahmed.Before independence, when GM Madani was the chairman of DIT (currently Rajuk), he allotted lands to Pakistani citizens in Dhaka city at the market price. Madani allotted the land of these four houses to somebody named Waqar Ahmed in 1960-63. After the independence of Bangladesh, the family of Waqar started to live permanently in Pakistan. These houses were included as abandoned properties as none was claimant of these houses in 1972. In this regard, a gazette was published on 23 September 1986.After the publication of the gazette, a certain Waziuddin was given power of attorney by a forged signature of the previous owner Waqar Ahmed. Through that power of attorney, he filed a case with a civil court in Dhaka on 13 August 1986 challenging the government gazette. He concealed information and filed four cases at the settlement court, claiming that these houses were included among the abandoned properties. He also forged the signature of Waqar in the document.The settlement court in its verdict on 14 October 1992 said these houses were not abandoned properties. Waziuddin, however, could take not over the houses.Earlier, identifying himself as son of Waqar, a certain Firoz Ahmed claimed to be owner of property in Boro Katra of Dhaka (holdings 11 and 13), filed a case and lost the case. He filed a review petition. In the petition, Firoz Ahmed claimed to be only son of Waqar Ahmed and claimed his father has gone to Europe for treatment. But the actual Firoz Ahmed and his father Waqar Ahmed were still in Pakistan. Waziuddin made these forged records.Dhanmondi police arrested Waziuddin as the leader of a land forgery gang on 12 July 2007. He confessed to police that he occupied land through fake documents. After remaining in jail for a couple of days, he died in 2010. Waziuddins family now lives in a house on Road No 7 in Dhanmondi. His son Ekabbor Hossain is an Awami League member of parliament from Tangail-7. He said he knows nothing about the land and has no interest in it.A new chapterAlthough these houses were under the occupation of the government, the verdict of the settlement court was in favour of Waziuddin. As a result, the houses were dropped from the abandoned property list. Then certain influential quarters grabbed this opportunity. They brought Waqar Ahmed to Bangladesh from Pakistan.According to the verdict, Beximco Group vice chairman Salman F Rahman used the letterhead of the group to write to the home ministry on 8 March 2015, asking them to issue a visa to Waqar Ahmed. The home ministry accordingly sent a recommendation to Bangladesh High Commission in Karachi to issue a visa to Waqar. Waqar came to Bangladesh on flight PK-266 on a five-day visit on 13 April. On that very day, he received a birth certificate as a citizen of Bangladesh from Zone 1 of Dhaka South City Corporation. But he submitted the photocopy of his national identity card as a permanent resident of Pakistan when taking the visa for Bangladesh.The verdict also said Waqar applied for a machine readable passport (MRP) passport on 15 April within two days after arriving in Bangladesh. He himself, however, did not go to the passport office. Citing illness, he applied and his fingerprint was taken from a residence. The passport was issued in his favour on that very day.Director general of the immigration and passport directorate Major General Masud Rezwan said a written passport was issued in favour of Waqar Ahmed in 2007. The MRP was issued based on that passport.Asked how Waqar was given a Bangladeshi passport being a citizen of Pakistan, the DG said an investigation is underway in this regard. Waqar Ahmed did not come to Bangladesh after independence. The directorate of immigration and passport could not explain how the passport was issued in favour of Waqar Ahmed in 2007. The directorate is also investigating this.The permanent address Waqar Ahmed mentioned in his passport belongs to Rabeya Khatun, wife Abu Yunus. A security guard of the residence in the capitals Azimpur said no one named Waqar lived in the house.The phone number Waqar used in filing his passport papers is now used by Beximco Group senior manager Tasnin Hossain.When Tasnin was contacted over phone, he said, Waqar is the friend of my boss. I cant tell you more than that.The emergency address Waqar stated in his passport is a flat in a multi-storey building in Eskaton. The residents of the building said on Tuesday that the flat belongs to Beximco Group. But, papers say the flats owner is Jupiter Business Limited. The owner of the Jupiter is Mushfiqur Rahman. The flat, however, has been kept locked for one and a half years.The verdict of the court says Waqar Ahmed applied for the power of attorney with the sub-registrar office, immediately after receiving the passport. He also met the secretary of the housing and public works.The sub-registrar sent the power of attorney appeal to the inspector general of registration, saying such appeals are not issued as per rules. Waqar went back to Karachi on 17 April.Waqar, according to the verdict, appointed Ivy Real Estate Limited managing director Mushfiqur Rahman. From court documents, the address of the Ivy Real Estate is in Road 1, Dhanmondi. This is the address of Bell Tower, an office of Beximco.An investigation officer of the case said Mushfiqur was an employee of Beximco Group but he left his job two years ago.The government filed a writ petition on 4 May 2015 after Waqars power of attorney appeal.According to the writ petition, the verdict the settlement court passed was based on fake documents. Because, Waqar Ahmed submitted his passport to the housing and public works ministry on 18 June 2015 but he was invited to Bangladesh on 8 March.He came to Bangladesh using a Pakistani passport. While taking a Bangladeshi visa, he gave information that he has been living in Pakistan since 1952.The verdict also says the settlement court passed the verdict going beyond its jurisdiction. And so, the buildings will be considered as abandoned.Asked whether there would be any criminal case for occupying the governments property, attorney generalMahbubey Alam told Prothom Alo, This isnt my work. But this is true that those who claimed the property have lost (the case).In a written statement, Salman F Rahman told Prothom Alo, Nowhere in the High Court verdict was it mentioned that Waqar Ahmeds documents were fake. The attorney general tried to prove Waqar a Pakistani citizen. But even the AG nowhere in his statement said those documents fake.Salman F Rahman, ruling Awami League president Sheikh Hasinas adviser, did not comment on Waqars activities like quick issuance of Bangladeshi passport, managing Bangladeshi birth certificate and using of Beximcos address.The four building are still in the possession of the government. According to the court verdict, the houses have been abandoned property since independence of Bangladesh.Executive director of the Transparency International Bangladesh (TIB) Iftekharuzzaman told Prothom Alo that many influential people try to become owners of property using fraudulent ways.Sometimes they are successful in their attempts. However, these four houses will remain an example that if concerned persons are conscious, they can protect government property, he added.*This report, originally published in Prothom Alo print edition, has been rewritten in English by Rabiul Islam and Imam Hossain
Share Andrew SchneiderMidtown Houston, Sunday morning, August 27, 2017Could tunnels under Houston help reduce the risk of flooding during major rain storms? That’s the question Harris County hopes to answer. The county commissioners approved a study to determine whether building such large storm water tunnels is feasible.The tunnels would range from 30 to 40 feet in diameter. Construction would have to dig 100 to 200 feet down, cutting through everything from clay to sand.Why so deep? “Unfortunately, our land is very flat here,” says Russ Poppe, executive director of the Harris County Flood Control District, “and one of my requirements for making sure this is going to work is these tunnels have to work without the need for pumps during a rain event. They have to work by gravity.”The study aims to determine whether such a project is doable with today’s technology and, if so, how much it would cost. Poppe says building such tunnels in other parts of the country has cost up to $100 million per mile.
Explore further Credit: CC0 Public Domain Scientists conducting experiments with gene-splicing tools such as Cas12a want to know if such tools could one day be used to edit the human genome to improve health and well-being—removing genes that cause heredity diseases, for example. While such research holds great promise, existing gene-splicing tools are currently considered too unreliable for use in humans. They sometimes cut the wrong segment, for example, or have problems correctly inserting the right segments. There is also concern about damage to the parts of a DNA strand adjacent to the target of cutting—the PAM. In this new effort, the researchers have engineered variants of the Cas12a nucleases that they claim offer an expanded targeting range that includes some previously inaccessible PAMs.The team reports that one variant in particular, enAsCas12a, did not require an extended transfusion-transmissible (TTTV) virus PAM—which is, of course, needed for AsCas12a. It also had on average two-fold higher genome editing activity with canonical TTTV PAMs as compared to AsCas12a wild types. And the expanded targeting range was increased seven-fold. They report further that they successfully grafted a part of a mutated segment from enAsCas12a onto AsCas12a to improve its activities. The researchers claim that the development of enAsCas12a allows for more efficient multiplex gene editing and offers endogenous gene activation and C-to-T base editing. They also engineered another variant called enAsCas12a-HF1 with the goal of reducing higher than normal off-target effects seen with enAsCas12a.The group concludes their report by claiming that the AsCas12a variants they engineered offer other researchers greatly improved targeting ranges, on-target activities and a higher degree of exactness in gene splicing using Cas12a nucleases.
