Traffic-Jams-in-Sri-Lanka

BY T.V. PERERA

At the turn of the century, chaos and anarchy ruled the streets of Colombo, and that was not because city traffic was a mess then as it is now. Everyone will agree that traffic in Colombo has worsened in recent times; slow moving on all main trunk roads into the city not only during rush hours but also at normal times, and getting worse in the heart of Colombo. If Colombo is to accommodate the growing number of vehicles on its roads, the road network would have to be increased by three-fold in the not too distant future.

Colloquially known as traffic jams or traffic snarlups, traffic congestion is a transport condition characterized by slow speeds, longer trip times and increased vehicular queueing. When traffic is great, interaction between vehicles slows the speed of the traffic stream which results in congestion. Likewise, as demand approaches the capacity of a
road or its intersections, extreme congestion sets in. Traffic congestion also occurs when a column of traffic generates demand for space greater than that available, when vehicles are fully stopped for periods of time and also due to incidents such as a crash or roadworks which may reduce road capacity below normal levels.
According to the Time magazine, Sao Paulo in Brazil has the world’s worst daily traffic jam with over 300 kms of cummulative queues around the city during the evening rush hours. Last year, Mumbai was the worst city for traffic chaos where drivers can expect to spend an average 65% extra time stuck in a gridlock.

Individual incidents such as accidents or even a single car braking heavily could cause congestion, yet traffic research still cannot fully predict under which conditions a traffic jam as opposed to heavy but smoothly flowing traffic may suddenly occur. Of the over 4.4 million vehicles registered, around 2.7 million are on the roads causing the Colombo roads to be full with traffic congestion as an average 250,000 vehicles made up of 15,000 buses, 10,000 trucks and 225,000 private vehicles enter the city daily.

A man-made menace, traffic congestion has a number of negative effects such as being detrimental to the development of a country, killing productivity, and is a national waste. Not only does productivity and the sense of well-being go astray, it also leaves people angry, exhausted and depressed. To get stuck in a traffic jam of stress is really frustrating. Vehicle numbers increasing without any plan to expand road conditions and manage road discipline, is plainly visible.

The increasing vehicles contribute to long lines on the road yet no one seems to be interested in taking any positive and effective action other than the police which is responsible for controlling this mess. Successive governments have indicated intentions of taking corrective measures but nothing has been done to control road traffic which besides being annoying, is costing us billions of rupees and a massive financial and manhour loss as a result of no vehicular control in the Greater Colombo areas. Statistics reveal that there are 130 vehicles per 1000 people out of which 66% are motor cycles while three-wheelers and cars make up 45 vehicles per 1000 people. Very soon the number of vehicles on the road could grow to 5 million and there will be 250 vehicles per every 1000 persons which may concentrate around the city. This is contrary to the country’s needs of fewer vehicles carrying more people.

Nanotechnology in Agriculture System 0 468

By: Chantal D.

Sources:  Agronomy

Agriculture is the backbone of most of the developing countries in which a major part of their income comes from agriculture sector and more than half of their population depends on it for their livelihood.  The current global population is nearly 7.7 billion with 50% living in Asia. A large proportion of those livings in developing countries face daily food shortages as a result of environmental impacts or political instability, while in the developed world there is a food surplus. For developing countries, the drive is to develop drought and pest-resistant crops which also maximize yield. In developed countries, the food industry is driven by consumer demand which is currently for the fresher and healthier food products.

Specifically in agriculture, technical innovation is of importance with regard to addressing global challenges such s population growth, climate change and the limited availability of important plant nutrients such as phosphorus and potassium.

Nanotechnology has gained intense attention in the recent years due to its wide applications in several areas like medicine, medical drugs, catalysis, energy and materials. Those nanoparticles with small size to the large surface area (1-100nm) have several potential functions. These days, sustainable agriculture is needed. The development of nonchemical has appeared as promising agents for the plant growth, fertilizers and pesticides. In recent years, the use of Nano materials’ has been considered as the alternative solution to control pant pests including insects, fungi and weeds.

Despite these potential advantages, the agricultural sector is still comparably marginal and has not yet made it to the market to any larger extent in comparison with other sectors of nanotechnology application.

Nanotechnology helps agricultural sciences and reduce environmental pollution of pesticides and chemical fertilizers by using the nano particles and nano capsules with the ability control or delayed delivery, absorption and more effective and environmentally friendly and production of nano -crystals  to increase the efficiency of pesticides for application of pesticides with lower dose.

In the agricultural sector, nanotech research and development is likely to facilitate and frame the next stage of development of genetically modified crops, animal products inputs, chemical pesticides and precision farming techniques. The use of nanotechnology in agriculture has been mostly theoretical but it has begun and will continue to have a significant effect in the main areas of the food industry development of new functional materials, product development and design of methods and instrumentation for food safety and bio-security.

‘’Work harder than you think you did yesterday’’ 0 677

Athula Seneviarathne
Athula Senevirathne Chairman, SDK United Agri Ventures (Pvt) Ltd.

By T.V.Perera

Appalled by the rise of undernourishment during the past one and a half decades reaching an alarming estimated 821 million people by mid last year, the World Congress on Food and Nutrition met in December in Dubai, and focused on ‘Discovering new advances on food and nutrition for global citizens’. Meanwhile in Sri Lanka, SDK United Agri Ventures (Pvt) Ltd with its registered office at Pagoda in Nugegoda and plantations in Anuradhapura and Monaragala, has introduced high nutritional value food in Soya, and a vegetable oil under the name ‘Omega’ to the consumer market at a very affordable price, fulfilling the nourishment needs of Sri Lankans. BiZnomics recently spent time with the Chairman of United Agri Ventures (Pvt) Ltd Athula Senevirathne, listening to his success story. Commencing by revealing that on completing his academic career, his aim was to be a KDU military officer but that circumstances led him in 1986 to join Unilevers where he quickly rose in position as overall in-charge of the company’s 200 acre prawn farm in Chilaw.

SDK United AgriDuring tha period Senavirathne started his own gherkin cultivation employing 28 and subsequently, procured the prawn farm when Unilevers closed it down which became a turning point in his life.
He ran the prawn farm quite successfully catering to many a tourist hotel and customers such as
Japanese Airlines until he reached the top with exports to Australia. Explaining how he ventured into agriculture,

he states: ‘’During one of my trips to Anuradhapura to buy fish feed, a leading politician apprised me of maize and soya bean cultivated, and told me that cultivators were hard hit for lack of buyers for their produce. I then thought that I could do something for them’’. With banks assuring him financial assistance, Senevirathne moved forward, having in mind government decision to halt maize imports.
