THUWAL, Saudi Arabia, Oct. 07, 2021 (GLOBE NEWSWIRE) — Seaweed, as its unfortunate name suggests, can be a nuisance. It makes a mess of beautiful beaches. It bobs up and down in the waves in an unsightly blob. And it sticks to unsuspecting swimmers as they try to enjoy a dip. But despite its reputation with some ocean goers, seaweed just might be one of the most powerful tools we have to save the planet from manmade climate change while providing a path to realizing many of the UN Sustainable Development Goals.

Researchers from KAUST and Aarhus University believe seaweed is a model solution to climate change, biodiversity loss, joblessness, hunger and environmental damage. In a paper published in Nature Sustainability the co-authors outline how the cultivation and use of seaweed as a carbon capture technology, a job and tax revenue generator, and a food source, can help protect and restore our planet.

“Our research consolidates seaweed farming as an underpinning of a sustainable future,” Professor Carlos Duarte, study lead author said. “It is scalable, with a 2,000-fold increase potential, it generates valuable products while also contributing to carbon sequestration below the farm, it produces sustainable fuels, and it displaces carbon-intensive products, thereby providing a range of contributions to climate action. While growing at sea, seaweed forms an ecosystem that delivers multiple benefits to the marine environment.”

The cultivation and use of seaweed, the authors believe, will directly support six of the UN Sustainable Development Goals (SDGs), and indirectly support several others. Achieving zero hunger, supporting good health, making clean energy affordable, as well as supporting industrial innovation, climate action, and ocean conservation, are all outcomes of cultivating seaweed. Not only is the plant climate positive, profitable, and edible, but it promises to feed and employ millions while preserving the planet and fostering poverty reduction and gender equality.

“Seaweed provides wonderful materials for a range of applications, grounded in their amazing diversity, as seaweed are as far apart from a genomic perspective as mushrooms and elephants. This genomic diversity provides a phenomenal source of new materials across a range of industries, from food, to fuels and plastics,” Duarte said.

The pitch, as much as there is one, is that seaweed cultivation must be ramped up significantly. This, of course, might encounter roadblocks in legislatures around the world as western regulations, where seaweed farming is just starting, are quite unwelcoming to seaweed aquaculture. The paper outlines in broad terms the objections that could be raised and addresses them in turn.

“Because seaweed farming is a new industry in western nations, existing regulatory frameworks do not facilitate its development. In some nations it is easier to get a concession for marine oil and gas extraction than for a seaweed farm. Creating a friendlier regulatory environment that encourages, rather than deter, seaweed farming will be critical to delivering on its potential.”

“Currently, seaweed farming occupies about 2,000 Km2 of land, compared to about 60 million Km2 land food producing systems occupy. We consider that about 4 million Km2 of ocean can support seaweed aquaculture while delivering positive impacts on the marine environment. In the rump-up to COP26, we consider that scaling seaweed farming can be a wedge of a regenerative approach to our oceans, delivering climate action while alleviating hunger and poverty,” Duarte said.

Professor Dorte Krause-Jensen from Aarhus University adds that sustainability standards and consideration of the carrying capacity for seaweed farming need be in place to avoid potential unattended negative consequences the farming.

“The utilisation of seaweed in a cascading biorefinery extracting biomolecules sequentially, offers a path to maximise the value of the biomass and render seaweed farming profitable, even in Western countries where costs are higher” said senior researcher Annette Bruhn of Aarhus University. “Promoting sustainable seaweed cultivation as an emission capture and utilisation technology supporting the circular bioeconomy, calls for a cross-sectorial approach to solving societal challenges. We need a disruption of the traditional way of thinking climate, environment and resource provision in each their sector and we need partnerships between science, industry and authorities”.

Pakistan Expects 9.374 Million Cotton Bales in Crop Season 2021-22

The Cotton Crop Assessment Committee (CCAC) has assessed that the country is expected to have a production of 9.374 million bales in the crop season 2021-22, of which Punjab is likely to have an output of 5.44 with Sindh standing at 3.50, Balochistan 0.43 and Khyber Pakhtunkhwa 0.004 million bales. The assessment is based on the weight of one cotton bale at 170 kilograms.

The CCAC held its second meeting with Secretary Ministry of National Food Security & Research Mr. Tahir Khurshid in the chair to assess the volume of the current cotton crop in the country on Thursday.

Representatives of the provincial governments, Plant Protection Department (PPD), Trading Cooperation of Pakistan (TCP), Federal Seed Certification & Registration Department (FSC&RD), Pakistan Central Cotton Committee (PCCC), and All Pakistan Textile Mills Association (APTMA) attended the meeting.

Mr. Tahir Khurshid welcomed the participants and appreciated the stakeholders’ interest in the process of cotton crop assessment.

On the occasion, Cotton Commissioner Dr. Khalid Abdullah presented an overview of the cotton production scenario in the country. He stated that the weather and prices were favorable for cotton production, adding that the government’s announcement of intervention price enhanced the confidence of growers in crop management which resulted in high arrivals of cotton in ginneries.

The committee chair adjourned the meeting with a vote of thanks

Dealerships Make a Huge Increase in Own Money Amid Global Crisis

Delayed deliveries are becoming an increasingly bothersome mainstay of the Pakistani car market in more ways than one. On the one hand, the standard procedure entails car buyers having to wait for a long time (sometimes as long as a year) for their cars to be delivered. Those who want their cars to be delivered early have to resort to paying illegal premiums called ‘own money’ to dealerships.

Despite the government’s efforts, the own money culture is exacerbating. A media outlet recently reported that car dealerships have increased the amount of own money on the purchase of new locally assembled vehicles to Rs. 400,000.

The President of the Car Dealers Federation, Shehzada Saleem, told the media outlet that the own money on vehicles with engine capacities between 650cc and 1000cc has been increased from Rs. 100,000 to Rs. 250,000.

Additionally, the own money on the Suzuki Cultus has gone up from Rs. 75,000 to Rs. 250,000. Saleem added that the Honda Civic is currently warranting own money of up to Rs. 300,000, while that on the Corolla Altis Grande has been increased to Rs. 400,000.

A few weeks ago, a car dealer told the media that the own money on crossover SUVs like the Kia Sportage, the Hyundai Tucson, the DFSK Glory 580, and the MG HS ranges up to Rs. 700,000.

Based on latest reports, the following are the amounts of premium being charged against some popular vehicles in the market:

The root of this in the local car industry is believed to be the lack of transparency and active law enforcement by the concerned authorities.

The government had stated on several occasions that it is working on eradicating the own money culture from the market but there seems to be a lack of substantial follow-up on its claims so far.

Work on Dasu Hydropower Project to Resume Soon

The Ministry of Water Resources has held out assurance to the National Assembly Standing Committee on Water Resources that the talks, underway with the Chinese authorities on the safety and security of Chinese workers engaged in Dasu Hydropower Projet, will yield results and the work halted in July 2021 in the wake of a terrorist attack will resume soon.

The National Assembly panel meeting, chaired by Nawab Yousuf Talpur on Thursday, also discussed the issue of low water supply to Punjab.

It is to note that the work on Dasu Hydropower Project could not be resumed despite the government of Pakistan’s assurances to Chinese authorities regarding the security of Chinese workers. However, the Ministry of Water Resources officials were confident that the work would soon be resumed as talks were underway with the Chinese authorities.

“The main civil work has been closed since the attack on Chinese engineers in July,” said the officials.

Regarding a low release of water to Punjab, Chairman Indus River System Authority (IRSA), Saif Anjum, briefed the committee on water shortage. He said that the water supply in the Chashma Right Bank Canal was 34% down.

Chairman WAPDA, Lt. Gen. Muzammil Hussain, said the release of water was the job of IRSA, as it controlled it. “We release as much water as we are told to release,” said Chairman WAPDA.

Member Khyber Pakhtunkhwa IRSA said there were reasons for water scarcity. “The main canal needs cleaning and water is stolen. After 80 miles the Punjab border starts, so there are losses, which cannot be controlled,” he said.

Joint Secretary Water Resources informed the committee that Punjab wanted to take its share of the Chashma Right Bank Canal immediately and the agreement regarding this was almost complete. The committee directed implementing the CCI decision on control of the Chashma Right Bank Canal.

The Chairman IRSA presented the statistics of water supply in Kharif season to the provinces. He said IRSA distributed water to all provinces according to the constitutional water share as per the 1991 water accord.

Raising an objection to the statistics shared by Chairman IRSA, Sindh Irrigation member said Sindh was facing 4% more shortage than Punjab. He said that IRSA was not distributing water as per the IRSA Act. In Kharif, Guddu Barrage faced a 35% shortfall and Kotri faced a 60% shortfall. He urged IRSA to distribute water as per the formula determined by the 1991 accord.

Wasim Akram Reveals Why He Doesn’t Want to Coach Pakistan Team

Legend Pakistani pacer, Wasim Akram, has revealed that he has no intention of taking up any coaching role with the national team anytime in the near future.

During a recent interview with Cricket Pakistan, the former captain said that one of the biggest reasons for not taking up any role with the national team is that he can’t tolerate the abuse coaches get online.

Akram went on to say that although the passion of Pakistani cricket fans is understandable and their anger is justifiable, the foul language which they use when the team doesn’t perform well is unfathomable.

He added that the Pakistani fans must understand that although a coach can devise any plan before the match, it is up to the players to implement that plan on the pitch.

Wasim Akram represented Pakistan in 104 Tests and 356 ODIs, claiming 414 and 502 wickets respectively. After retiring from the national side, he moved behind the mic and became a commentator.

Although he has mentored Kolkata Knight Riders (KKR) as a bowling coach in the IPL and worked with Islamabad United, Multan Sultan, and Karachi Kings in the PSL, the former left-arm pacer has never accepted any coaching role with the national cricket team.
