Future threats and measures
Climate change refers to any significant change in the measures of climate lasting for an extended period of time. In other words, climate change includes major changes in:
among other effects, that occur over several decades or longer
It is based on data that spans thousands of years, collected and analyzed using various scientific methods.
Climate Change and the Greenhouse Effect
The major cause of climate change is global warming caused by the Greenhouse Effect, which is caused by gases known as the greenhouse gases.
How the Greenhouse Effect causes Climate Change:
Bangladesh: An overview.
Bangladesh is trapped between the Himalayas in the north and the encroaching Bay of Bengal to the south.
Bangladesh is most vulnerable to natural disasters due to the frequency of extreme climate events and its high population density.
According to National Geographic, Bangladesh ranks first as the nation most vulnerable to the impacts of climate change in the coming decades.

Humans release more and more greenhouse gases into the atmosphere, and this leads to global warming.
Global warming then causes climate change.

Climate change is expected to trigger a migration like no other.
Experts expect about 250 million people worldwide to move by 2050. Of those, 20 million to 30 million climate change refugees are expected to be in Bangladesh, likely the largest number from one place.

Immediate Impacts on Bangladesh:
The Bay of Bengal is located at the tip of the north Indian Ocean, where severe Cyclonic storms as well as long Tidal waves are frequently generated
Almost one forth of the total population of the country live in the coastal areas of Bangladesh
With the rise of Sea-level up to one meter only, Bangladesh could lose up to 15% of its land area and around 30 million people living in the coastal areas of Bangladesh could become Refugees because of Climate Change impacts.

The poor and vulnerable in Bangladesh are constantly adjusting to climate change by raising their houses above the flood level or changing crop types.
The Government of Bangladesh has invested more than $10 billion during the past 35 years to make Bangladesh less vulnerable to natural disasters.
Despite these efforts, the direct annual cost of natural disasters over the last 10 years is estimated to be between 0.5% and 1% of Bangladesh's GDP (UNDP).
The economic impacts of future climate change are expected to be larger and could even reverse the recent gains in the areas of economic growth and population control.

Agriculture and Fisheries:
The impacts of Climate Change such as - Extreme Temperature, Drought, and Salinity Intrusion etc. are also responsible for the declining crop yields in Bangladesh.
Temperature and Rainfall changes have already affected crop production in many parts of the country and the area of arable land has decreased to a great extent.
The Salinity intrusion in the coastal area is creating a serious implications for the coastal land that were traditionally used for rice production
The fisheries sector has also experienced an adverse affect because of the impacts of Climate Change. The fisheries sector contributes about 3.5% of the GDP in Bangladesh and people depend on fish products in order to meet up majority of their daily protein requirements.
There are around 260 species of fish in the country and almost all the varieties are sensitive to specific salt and freshwater conditions
Water Resources and Hydrology
In a high density country like Bangladesh, the effects of Climate Change on the Surface and Ground water resources will be very severe and alarming. Riverbank erosion is a constant presence.
Changes to water resources and hydrology will have a significant impact on the country’s economy, where people mostly depend on the Surface water for Irrigation, Fishery, Industrial production, Navigation and similar other activities.
Cities and Towns situated along the Coastal belt in Bangladesh are at the Front line of Climate Change related Disaster impacts and could experience severe damage directly because of the Sea level Rise and Storm Surges at any time.
As a consequence, it hampers usual productivity during and after major floods and hence increases the vulnerability of the urban poor by many folds.
It should be mentioned here that, around 40 per cent of the urban population in Bangladesh lives in the Slum and Squatter settlements of the major cities, which are highly vulnerable in times of flooding, raising the risk of disaster even higher.
In Bangladesh, women are especially vulnerable because of the gender inequalities in the Socio-economic and Political institutions.
During the 1991 cyclone and storm surge in Bangladesh, the death rate in case of women was almost five times higher than the men, because men were able to communicate with each other in the public spaces, but the information did not reach most of the women timely.

The International Organization for Migration says about 70 per cent of the slum dwellers have come to Dhaka because of climate-change adversity
Nearly 60% of the slums in the city have poor or no drainage and are prone to frequent flooding
Famous for wetland area, but due to climate change those wetland is facing untimely flood, heavy flood and drought also.
Syhlet is bordered by the Meghalaya, Assam and Tripura states of India to the north, east and south, so it is on threat of flash flood frequently. Especially in monsoon the possibility of flash flood increases drastically. Heavy rainfall on upper basin induces the flash flood in Syhlet. In other hand hill degradation, unplanned cultivation, deforestation increases the damage caused by flash flood in this region.
Land slide and Cyclones
Land-slide in 2007 recognized as climate induce disaster but flash flood and land slide mostly related to human made soil erosion and deforestation.
Unplanned cultivation, hill degradation and deforestation are increasing the possibility of climate induce hazard.
Incidence of diarrhoea was found to have positive correlation with total annual rainfall in Rajshahi (drought prone) and Patuakhali (saline prone)
Skin diseases and malnutrition are also found to be positively correlated with temperature differentials in both Rajshahi and Patuakhali,
DISTRICT-WISE IMPACTS OF CLIMATE CHANGE
Rangpur region is close to the Himalayan mountain range, a moderate cold spell is sweeping over the region from midnight to morning.
Prof Dr Masum A Patwari, chief of the Geography and Environment Science at Begum Rokeya University in Rangpur, said: “The northern region of the country is experiencing the impact of global climate change.”
Barisal basically depends on agriculture. For that reason, climate change effects on crop yields will affect food production capability severely.
Without new coping strategies farmers will earn less from HYV rice production in many areas, including losses of 10.5 percent Barisal and 7.5 in Chittagong. Many upazilas have already suffered large yield losses and substantial price reductions from rising salinity, and this will continue as long as the sea-levels rise and salinity increases.

Bangladesh is the country most at risk from the impacts of climate change, according to the 2013 Climate Change Vulnerability Index (CCVI) prepared by international consultancy firm Maplecroft.
Maplecroft has also calculated climate risks that will be faced by 50 cities around the world over the next 30 years. The study found five cities at “extreme risk”, of which three are in South Asia – Dhaka (in Bangladesh), Mumbai and Kolkata (both in India).

ADAPTATION IN BANGLADESH
Climate change is perhaps the biggest problem facing the world in the 21st century.
It is a global issue, and can not be prevented from happening.
And, through scientific analysis and in-depth research, it has been found that:
HUMANS ARE MOSTLY RESPONSIBLE.
The effects of climate change cannot be stopped.
Therefore, to survive, we must adapt to the changes.
Let's take a look at how Bangladesh is adapting to climate change.
WHAT BANGLADESH HAS TO ADAPT TO:

Agriculture is perhaps the sector most threatened by climate change, as Bangladesh is still very much dependent on its agriculture to maintain its economy.
Recognizing that, significant research has been carried out to produce special kinds of crops that are resilient to high salinity, require less water in times of drought, and provide more yield faster:
Cultivation of suitable crops, fruits and different technology in drought prone areas:
Drought tolerant rice variety
: BRRI dhan 56, BRRI dhan 57
Short duration rice:
BRRI dhan 33, BRRI dhan 39, BINA dhan 7
Early rice variety:
BRRI dhan 42 and BRRI dhan 43
Drought tolerant fruits :
Jujube, pineapple and other fruits, maize, country bean etc

Since the 1970s, the Government of Bangladesh, with the support of development partners, has invested in:
flood management schemes to raise agricultural productivity of low-lying rural areas and to protect them from extremely damaging severe floods;
flood protection and drainage schemes to protect urban areas from rainwater and river flooding ;
coastal embankment projects designed to raise agricultural productivity in coastal areas by preventing tidal flooding and incursion of saline water;
over 2,000 cyclone shelters to provide refuges for communities from storm surges and 200 shelters from river floods;
comprehensive disaster management projects, involving community-based programmes and early warning systems for floods and cyclones;
irrigation schemes to enable farmers to grow a dry season rice crop in areas subject to heavy monsoon flooding and in other parts of the country, including drought-prone areas;

Local Level Adaptation
The most common forms of private adaptation activities are:
temporary migration of adult men for day labor
construction of platforms to protect livestock
storage of food and drinking water prior to extreme events.
The preferred public adaptation activities from a local perspective include:
(a) environmental management (mangrove preservation, afforestation, coastal greenbelts);
(b) water resource management (drainage, rainwater harvesting, drinking water provision, and flood control);
(c) Infrastructure (roads, cyclone shelters);
(d) livelihood diversification and social protection for fishers during the cyclone season;
(f) agriculture, including development of salt-tolerant and high-yield varieties and crop insurance;

Whole Government Approach (WGA)
The Bangladesh Climate Change Resilience Fund
Bangladesh Climate Change Resilience Fund (BCCRF) is a coordinated financing mechanism by the Government of Bangladesh, development partners and the World Bank to address the impacts of climate change.
established in May 2010
with financial support from Denmark, European Union, Sweden and United Kingdom. Switzerland, Australia and United States subsequently joined the fund.
This mechanism is enabling the Government to channel in over US$188million grant funds to millions of Bangladeshis to build their resilience to the effects of climate change.
The Bangladesh Government leads on the management and implementation of BCCRF.

Now let's take a look at the Government's approach.
Future threats and measures:
The future is unpredictable, yet one thing is certain:
climate change is an inevitable threat, and Bangladesh is doing all it can to adjust and adapt to the hardships that it faces.
Recognizing the increased future vulnerability of its development objectives to climate change, the Government of Bangladesh prepared the National Adaptation Program of Action (NAPA) in 2005.
Bangladesh Climate Change Strategy and Action Plan first prepared in 2008, modified and approved by the
Government in 2009 with wide consultation with
Government and non government sector, community based organization, development partners, experts, academia etc.
BCCSAP – 2009 is a one of the first landmark documents among the developing countries.

agricultural research programmes to develop saline, drought and flood-adapted high yielding varieties of rice and other crops, based on the traditional varieties evolved over centuries by Bangladeshi farmers;
coastal 'greenbelt' projects, involving mangrove planting along nearly 9,000 km of the shoreline.
(g) fisheries, including storm-resistant boats and conflict resolution between shrimp and rice farmers;
Indigenous knowledge and methods are also used in local-level adaptation.
In the end...
It is ultimately up to us, as individuals, to do our own parts to save the world.
While public and private methods may help the masses, we can all do our own bit to slow down climate change.
Don't waste water or electricity.
Walk, or use a bicycle as often as possible.
Eat less meat.
Support renewable energy sources.
THINK GLOBAL, ACT LOCAL.
As a small, developing nation, Bangladesh will always face challenges.
But unity and adaptability will build resilience for us in the long run.
Let's save our home!
