5. Introduction
Climatic variability is one of the major factors influencing bio-physical system and
eventually the rural livelihoods in the drought-prone areas of Bangladesh. It
directly affects the agriculture. Recent trends of temperature and rainfall show that
temperature has been increased and rainfall pattern has been changed in the Barind
region of Bangladesh. In Bangladesh, drought is a recurrent phenomenon. During
the last 50 years, Bangladesh suffered from more than 20 drought conditions, and
severe droughts took places in 1973,1978,1979,1981,1982,1989,1992,1994 and
1995. Major drought can cause greater damage to crops and properly than a flood
or cyclone and also can affect more people over a wide area. The north-western
part specially the upper Barind tract of Bangladesh is considered to be the most
drought-prone. This region is relatively drier and receives much lower rainfall in
compare with rest of the country.
7. METHODOLOGY
The primary data for the present study are collected though
structure questionnaire survey, interview with key
informants and field observations, and secondary data are
collected from Bangladesh Meteorological Department,
census report, official documents, previous survey records
etc.
8. MAJOR FINDINGS
Variability in temperature
Variability in rainfall
Farmers current adaptation practices:
i. Changes in cropping pattern
ii. Adaptation of drought tolerant rice varieties
iii. Rainwater harvesting
iv. Weed control and reducing water loss
v. Changes in irrigation system
9. Variability in Temperature
Bangladesh Meteorological Department (BMD) has been analysis during the
period of 1979-2009 present study area which are identified to :
Average maximum temperature of Rajshahi is 42.73 degree celcius.
Rajshahi is the warmest place among any other area of Barind region.
Higher temperature increases evapotranspiration, lowers ground water
aquifer, dries the agriculture land creates drought situation.
April to middle of June ,create drought situation.
11. Variability in Rainfall
The average annual rainfall of the north-western part of Bangladesh
varies from 1400 mm to 1600 mm.
80 % of rainfall occurs during the monsoon period.
Being change climate, present average rainfall in rajshahi 1410 mm.
Low rainfall is associated with long dry spells throughout the season.
Moreover ,climate variability may further aggravate drought situation in
the Barind region.
13. Annual Average Rainfall Variability in the Barind Region
Weather Stations C.V.(%) Rainfall Conditions
Bogra 22.42 Moderate Rainfall
Dinajpur 22.42 Moderate Rainfall
Rangpur 26.44 Heavy Rainfall
Rajshahi 21.21 Relatively Low Rainfall
14. Changes in Cropping Pattern
Barind Multipurpose Development Authority (BMDA), Barind
Environment Management Action Plan (BEMAP), Bangladesh
Agriculture Research Council (BARC) ,assist farmers to practice a new
types of cropping in the study villages to combat drought situation:
1. Robi (November to February) : Potato , Mustard , Onion, Pulses.
2. Khalif-1( also called T-Aush , March to May): Boro rice .
3. Khalif-2( May to October): Swarna,Bina-7,BRRI 28, BRRI 39.
15. Adaptation of Drought Tolerant Rice
Varieties
The present study finds that Bangladesh Rice Research
Institute (BRRI) has invented drought tolerant rice varieties
for the drought prone Barind Tract :
1. BRRI 32 7.IR71604-4-14-7
2. BRRI 39
3. BRRI 28
4. Parjia
5. IR 50
6. Bina-7
16. Rainwater Harvesting
An important adaptive measure to combat water scarcity during
drought period.
Water control structures for irrigation during dry season.
They preserve rainwater in ponds , mini canals, etc.
Government has construed a number of water control structures
which are well-planned and effective to reserve water during dry
season.
About 64.07% preserve rainfall water.
17. Weed Control and Reducing Water Loss
In study Area ,farmers usually use hand hoe named Ronester :
It helps to minimize soil moisture loss.
Also helps consuming loss water to reduce the drought impacts after
extended dry spells.
It is found that 81.82% and 97.94% of farmers try to control weed for
reducing water loss as an adaptation measure in two major villages.
18. Changes in Irrigation System
Choice of crops according to the availability of irrigation
facilities.
They use Polyvinyl Chloride (PVC) pipe to supply water to
their lands and it helps them to reduce water loss during
drought .
19. Conclusion:
In the study area, droughts have become more frequent
phenomena in Barind region.
For this causes , Rajshahi is a crucial factor for availability ,
irrigation , cropping pattern, fish cultivation , and livestock
rearing.
To reduce the problem, various adaptation such as drought
tolarent rice varieties, kitchen gardening , jujube intercropping
etc.
20. Recommendation
To combat future climatic variability improvement in
irrigation facilities can help farmers to increase agricultural
production.
Government and NGO should take some necessary steps to
drought prone area people.
