Ride-sharing Mobile Apps Services: A revolution in Public Transportation


E-hailing service has been very popular globally for over seven years. In Bangladesh Ride-sharing services becomes popular on last two years. This services have gained popularity among the urban commuters mainly in Dhaka and Chittagong City area. The services are car rides, motorcycle rides and some offering both. The service operates on a simple principal. When in need of a ride, a person can send a pick-up request through the ride sharing smartphone app, and then meet with the rider at a designated point. The rider then drops the passenger to his or her destination. The fare is fixed, and is calculated by the app based on the starting point and the destination.



In 2016, ride-hailing tech companies stormed the Bangladeshi market and starts services in only Dhaka. In November 2016, Uber, the San Francisco-based ride-sharing tech giant has launch the dysfunctional public transportation system and taxi service in Dhaka. In a matter of just a year, the company has not only gained immense popularity but has also paved the way for several local tech initiatives to arrive in the market. But now there are more than ten companies are now providing this ridesharing services in Dhaka as Uber, Pathao, Chalo, Muv, Dhaka Moto, Bahon, Amar Bike, Amar Ride, Taxiwala, Dako, Ezzyr, Goti and Hellow Ride, all of whom have created a booming e-hailing market. In considering the women passengers some services is launch only for women as Obon, Lily, Pink SAM etc.

Typically one car is used by one family now that same car can be shared by others, meaning lesser cars on roads. This will definitely help improve traffic conditions. These ride-hailing services make our cities more accessible and pollution free. Ride sharing services mainly the motorbikes can offer fast movement through the city area, which is not possible for CNG-run auto rickshaws and cars. But there are some scope on increasing the services of e-hailing services as improve the quality of cars/bikes; monitor the quality of car/bikes in periodically; give the leadership training to vehicle drivers; promote to abide traffic laws; follow the Ride-sharing Service Guidelines, 2017; have to wifi facility in cars; have to drinkable water facility, available vehicle for women and kids passenger; have to special privileges for person with disabilities PWDs; online payment system as billing system; the apps should have Bangla version; have option on use the app in offline mood; have to increase the services area as out of city and entire Bangladesh, increasing the number of vehicles, reduces the fare cost and take minimal charges of ride-sharing agency from drivers.

Finally, this services brings comfort to commuter and escaped from the monopoly of Auto-rickshaws, public transport (bus) and brings a revolution in Public Transport. This service is also supplement the government vision Digital Bangladesh.

Vertical Gardening in City Sculpture/Infrastructure Increases the Aesthetic beauty of City and Help in Tackle Climate Change

A vertical garden is a garden that grows upward (vertically) using a trellis or other support system, rather than on the ground (horizontally). Vertical Gardening in City Sculpture/Infrastructure might increases the aesthetic beauty of city as well as tackle the climate change. Due to rapid urbanization the city are severely losses it land as well agricultural lands are reform into housing or industry. For that reason the space for gardening is shrinking. In many cases for more traffic accessibility the road and footpath are bound to extend. So it is hard to plantation or gardening besides the roads.  In that context, if we can promote the vertical gardening in city areas then the beauty of city will increases and tackle the air and sound pollution in city area. My proposal is if we can start vertical gardening in the pillar of flyover which increases the aesthetic beauty of city as well as support in tackle the city’s air and noise pollution. This process also creates entrepreneurship at community.





Process:

Growing trees/plants/ Creepers and shrubs in plastic sacks, giant containers made of plastic sheets, bottles and bamboo, as well as other receptacles and using trellis or other support for tie in sculpture or infrastructure. 

Rationale:
  • This approaches is environment friendly and sustainable. We can uses our wastage materials as used plastic bottle, pipes, container in regards of tree growing.
  • By this approaches an entrepreneurship has developed in regards of developing, maintaining nursery and selling creepers and shrubs.
  • By this approaches a collective action has developed at city areas. Community people will take the rearing and fostering of this vertical garden.


Finally, the intensity of noise and air pollution of a city should be reduced and ultimately tackle the climate change.

Alcohol Consumption in Bangladesh is on the RISE


Alcohol consumption poses serious threat to human health and is responsible for causing more than 200 diseases. Alcohol consumption results in 3.3 million deaths per year worldwide. Of all deaths worldwide, 5.9% are due to alcohol use, a figure higher than deaths from human immunodeficiency virus infection (2.8%) and tuberculosis (1.7%). According to World Health Organization (WHO), it is among main four modifiable risk factors for no communicable diseases. In Bangladesh, the consumption of alcohol is strictly prohibited both as a social function and as a religious rite by most of the religions. Yet, the problem of alcoholism is becoming a threat to the nation’s welfare. Information obtained from law enforcement authorities, treatment providers and other sources indicate that problems of alcohol abuse have become quite common in Bangladesh.



Social Background:
Cultural and religious determinants have great impact on alcohol consumption among different classes of Bangladeshis. Considerable proportion of indigenous population of Bangladesh consume alcohol for social recreation, ritual and religious purposes. Alcohol consumption in some working classes like workers in morgue, boot makers and tea factory laborers is reported to be higher. Nonetheless, it has been reported that among people with higher income, alcoholic drinking is also popular and is considered as a sign of “modernity” or “westernized life style”.

Alcohol and government policies in Bangladesh:
According to the “Intoxicant Control Act” of Bangladesh (1990), alcohol means spirit or liquor of whatever kind (wine, beer), or any liquid containing more than 0.5% alcohol. Specific license is required for establishing a distillery or brewery, possession, storage and consumption of alcohol. Consumption of alcohol is illegal unless for: a) Muslim citizens who receive a permission for alcohol use on a health ground from either a civil surgeon or an associate professor of medicine, b) sewage cleaners, morgue workers, coolie (day laborer) in a tea estate, boot makers and indigenous people residing in Chittagong Hill Tracts or CHT c) international tourists and businessmen who consume alcohol in a licensed bar, and d) non-Muslim citizens (with permit). This act has some loopholes as; the act does not specify the health conditions for which a Muslim may be allowed to use alcohol and the decision rests on the authorized physician. Furthermore, because of multiethnic background of Bangladesh and to avoid interfering with old traditions and local culture, use of alcoholic beverages was announced as permissible for indigenous people after an amendment to this act in 2001. Therefore, there is partial ban on alcohol use. It is interesting that only the Muslim citizens are punishable under this act and others are not. There is no minimum age limit for drinking alcohol.

Types of liquor available:
Different types of beverages with varying alcohol content, available in different parts of Bangladesh. It can segmented in two ways as industrially produced name as ; Country liquor, Foreign liquor, Toddy, Beer and Spirit. All brands of Carew and company contain 42.8% ethanol. Homemade brews or Local alcoholic beverages called cholai, tari,Pochani, Ekchuani, Dochuani and Bangla Mad consumed by the lower socioeconomic classes.

Prevalence of alcohol use in Bangladesh:
WHO and Food and Agricultural Organization reports in 2004, 2011 and 2014 have shown an increasing trend in alcohol per capita consumption (APC) in Bangladesh. Binge drinking or heavy episodic drinking has been reported in 20.2% of Bangladeshi drinkers and the majority of them were found to be within 25-44 age group. According to 2014 WHO report; alcohol dependence in Bangladesh was estimated to be 0.7% in general population. However, in certain professions or population are prevalence’s such as vehicle drivers, sex workers, substance abusers with, street (homeless) children (11-18 years old) and university students. There are roughly 4.6 million drug abusers in Bangladesh. Therefore, about 510,600 alcohol abusers likely exist among drug addicts. But alcohol use prevalence in Bangladesh is approximately 24 times higher than estimated legal consumers. Alcohol consumer is generally higher male than female.  Regarding the age of alcohol consumers in Bangladesh the majority are within 25 to 44 years of age.

Toxic alcohol ingestion:
According to epidemiologic studies on poisonings in Bangladesh, total of 635 deaths due to alcohol overdose and toxic alcohol ingestion have been reported since 1990s. Illegal homemade beverages came to attention after mass poisoning outbreaks of methanol happened in different parts of the country. Nineteen incidents of methanol mass poisoning were reported during 1998 to 2014 in Bangladesh. During the same period 273 deaths were reported from methanol toxicity. The other highly toxic alcohol, diethylene glycol, was responsible for 363 deaths during the period of 1990 to 1995 and the year 2009.

Alcohol-related morbidities:
Critical organ damages due to chronic toxicity of alcohol drinking such as chronic liver disease (CLD) and hepatocellular carcinoma have been observed in different extents in Bangladesh. Long-term effects on liver was studied among indigenous people of CHT with history of consumption of more than 60 g alcohol in each sitting over 10 years. Alcohol abuse is also instigate physical injuries from accident or violence.

Discussion:
Estimated prevalence of alcohol consumers in general population of Bangladesh is low (1.9%). The results were also consistent with low prevalence of alcohol use in countries with Muslim majority. However, we found that the alcohol consumption in Bangladesh is on the rise. Increase in domestic production, increased number of permits issued for drinking and massive amount of seizures of illegal liquor suggest that actual amount of alcohol use may be much higher than the official reports. This is probably due to the fact that many consumers purchase alcoholic drinks from illegal vendors and are still unaccounted for.  Higher prevalence of alcohol use among the university students, truck drivers, sex workers, substance abusers, homeless children, indigenous people, and in families with positive history for alcohol drinking, implies the need to formulate cost effective prevention programs for specific society groups and clusters. Targeted intervention among high-risk population to encourage them to consume alcohol within a safe limit or to quit drinking will be an effective measure.
