Résumé
The ongoing climate change will have significant effects all over the world.Because of these changes some areas will be losing the benefits which they are enjoying today and some will gain their economies.Maritime industry being global in nature will share the profits and the losses a region will be facing in future.The international community is endeavoring to delay these changes but we have to be realistic.Climate change is already underway and cannot be stopped.To secure our future, we must prepare ourselves and do our best to adapt to these changing conditions.Many studies have already been conducted to analyze the effects of these changes on different walks of life, but very little is studied to evaluate the effects of these variation on ports of the world.This dissertation examines the opportunities and impacts on ports studying the Arctic Region as that area will have maximum effects due to the global warming.In order to achieve the goal, firstly the economic imbalances due to the climatic affects in different regions are studied as they are the major sources for increase in global trade.History shows that whenever the trade patterns changes, the ports rises or falls with the changes.Today is a new turning point in shipping.With the melting of the Arctic ice cover new shipping routes are being opened.These will substantially shorten the shipping route for Europe and North-America to important trade destinations in the Pacific.This could mean in some instances a shortening of the shipping distance of up to 40 per cent.The study assesses the viability of Transarctic shipping in terms of distance, time and economics since the viability of Transarctic shipping is primarily an economic question as the power of free markets with increased demand for global transport and v logistics corporations are the decision makers when it comes to identifying new routing opportunities.The second attraction to maritime trade in the region is the opening of a new market of oil, gas and other minerals.Scientists have discovered world largest oil and gas reserves under the white ice of the Arctic Region.With the melting of ice, the access to these resources is also getting easier.This will increase the demand for ship transport for the oil and gas operations To assess the benefits of distance in adopting the Transarctic route, an empirical study using the Center of Gravity modeling is used by the author where the Canadian market is modeled for the containerized traffic.The study reveals that according to the data taken by the different sources in 2006, the Canadian ports in north or north east are in better position to be a hub port for the container market in Canada.But at present due to non availability of shorter route between North East Asia and northern Canada, shippers are calling port of Vancouver at the west coast of Canada due availability of a shorter route across the Pacific ocean.The study concludes that with the changes in climatic conditions where many ports will be losing business, Arctic ports will have the opportunities to gain economies.But this all is not possible without improving the infrastructure availability which can minimize the total cost in the whole logistics and supply chain.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
