Climate change refers to any significant change in the measures of

climate lasting for an extended period of time→ temperature,

precipitation & wind patterns

Impacts of Climate change will not be uniform across the globe due to

differences in bio-physical & socio-economic conditions

(IPCC, 2007)

Magnitude of impacts of climate change depends on vulnerability of

individual nations & adaptive capacity to face consequences.

vulnerability →degree to which a system is susceptible & unable to

cope with the adverse effects of climate change , including climate

variability & extremes.

Developing countries → more vulnerable → structural weaknesses & low

levels of resilience & adaptive capacity → South Asia → most vulnerable

region of the world.

Adaptive capacity → potential or capability of a system to adjust

to climate change , including climate variability and extremes to cope

with consequences

(Vincent, 2004 and IPCC, 2001)

India → severely impacted countries by climate change as the Indian

economy is well tied to natural resources & climate-sensitive sectors →

Agri, Fisheries & Forestry (Chung et al, 2006 )

India → 2nd largest producer of fish → 5.43% to global fish

production (FAO 2015)

Rural fishing population → largely depends on reservoir fisheries

→ livelihood (Bene 2003)

Karnataka → 3rd highest area of total inland water bodies → production

potential of 264000 MT/year → 9th position in inland fish production

(DAHD, 2013)

Bhadra reservoir is the 3nd largest reservoir in Karnataka

Karnataka is likely to be more vulnerable to climate change than other

states

In terms of areas prone to drought, Karnataka is next only to

Rajasthan; 54% of Karnataka's geographical area is drought prone,

with drought affecting state's 176 taluks and 18 of its 30 districts.

Most parts of Karnataka could experience 1.5–2 °C warming →by as

early as 2030s under the likely high-emissions scenario(industrial

emission)

(Indian Institute of Science, 2014)

Climate change with reference to gender

Climate change is not gender neutral

Gender matters when it comes to vulnerability to climate change

Women and men play different roles in household livelihoods & therefore they experience the impacts of climate change differently

Household livelihood comprises of capabilities, assets & activities of individual

(CARE, PECCN, 2011)

Material and Methods used to study

objective 1

To assess the vulnerability of fisheries

dependent livelihoods on climate change

with reference to gender

Material and Methods used for assessing vulnerability of fisheries dependent livelihoods on climate change

• Composite livelihood vulnerability index approach→computes vulnerability indices by aggregating data for set of indicators

• Indicators used → exposure, sensitivity & adaptive capacity

• Under each indicator set of questions were asked to fishers (separately for fisher men and fisher women)

Exposure=10

Sensitivity =10

Adaptive capacity=10 (Rahman,2014)

• Respondents were asked to rank each question on a scale

ranging from 0-4

• Quantitative assessment of indicators was done to compute vulnerability

scores using formula V=E*S*(1-AC)

Where,V= Vulnerability E= ExposureS= Sensitivity AC =Adaptive capacity

0 1 2 3 4

no climate change effect

less climate change effect

moderate climate change effect

high climate change effect

extremely high climate

change effect

Primary data →indicator → normalized (rescaled

from 0-1) by using equation

Where,

IndexSi = normalized value of an indicator

Si=actual value of the same indicator

Smin & Smax = minimum & maximum values of same

indicator respectively

After normalization sub indices were used to compute

vulnerability scores.

• To test is there any significant difference between

perception of men and women about vulnerability due to

Climate change → Mann-Whitney U test

Hypothesis:

Ho: There is no significant difference between perception

of men and women about vulnerability due to Climate

change

H1: There is a significant difference between perception of

men and women about vulnerability due to Climate change

• To test any significant difference between perceptions

about Climate change between the villages →Friedman

test

Hypothesis:

• Ho: There is no significant difference between

perceptions about Climate change between the villages.

• H1: There is a significant difference between

perceptions about Climate change between the villages.

Livelihood →adequate stock & flow of food and cash to meet basic needs.(conway 2002)

• Human capital: Labour capacity; education; skills.

• Natural capital: Land; Access to common property

resources.

• Financial capital: wages; access to credit.

• Physical capital: water supply; housing; Fishing crafts &

gears.

• Social capital: social status; discrimination against women;

strong links with family & friends; traditions of reciprocal

exchange.

Respondents were asked to score these questions on a scale ranging from 0-4

Where,0 −no effect

1−less effect

2−moderate effect

3−high effect

4−extremly high effect

In each capital different number of questions were asked to both

fishermen & women i.e.., questions were taken from livelihood framework

by CARE Human capital -8

Natural capital -9

Financial capital -6

Physical capital -10

Social capital -5

Scores obtained from respondents were average to study the potential effects of climate change on livelihood of fishers

Scores of fisher men & fisher women were averaged separately to study who is more effected due to climate change

Total of both the scores were taken to measure the overall climate change effects on livelihood of fishers dependent on Bhadra reservoir

• To test is there any significant difference between perception

of men and women about effects of climate change on livelihood

capitals → Mann-Whitney U test

Hypothesis

Ho: There is no significant difference between perception of men

and women about potential effects of climate change on livelihood

capitals

• H1: There is significant difference between perception of men

and women about potential effects of climate change on

livelihood capitals

Over the years, reduction in size of Indian Major Carps is noticed by

fishers in Bhadra reservoir Eg: average size of Catla reduced from 8-9 kgs to 3-5 kgs

Reduced fish sizes due to increase in temperature →predicted, with

reductions individual maximum body weight projected from 2000 to 2050

2006, 2008 and 2012 water level in the reservoir →reached below

dead storage level (dead storage of 8.50 BCF at RL of 631.54 mtrs above MSL)

Fast depletion of water levels →report say only 13.5tmc ft of water left

in the reservoir & the situation is worse in 2016 which are considered as

the indication of drought condition in near future of Bhadra reservoir.

(Times of India 2016, May 25)

Till last summer → maintain water dead storage level up to 140 to

145 ft → 113.4 ft ≈ reduction in water level of 31ft

(Bhadra CADA)

Environmental flows in Bhadra River, Karnataka → fishing activities

are reduced & existing riverine water flows leads to changes in

livelihood options.

•Even native fish, fish habitat and riverine fisheries have been

severely impacted by changes in the hydrological regime and water

quality.

•Fish catches have declined drastically, which badly affected the fishers

who are highly dependent on fishing for food and income.

•Large fish have apparently more affected → Fish diseases have also

increased. (Harish Kumara et.al..,2010)

Inference → objective 1• Study has shown result that fisher women are more effected

compared to fishermen in Bhadra reservoir.

• When asked about present situation fishers responded that,

many fishers have migrated due to deficit fish catch observed

in Bhadra reservoir.

• Even in the media report (2015) it was mentioned that Bhadra

fishers livelihood is at stake fearing to which fishers are

vacating the villages (Vijaya Karnataka newspaper)

To study potential effects of climate change on

livelihood of fishers

H1: There is significant difference between perception of men and

women about potential impact of climate change on livelihood capitals

Potential effect on livelihood capitals• Overall score for potential effect on livelihood capitals was 2.87.• Fishers perceived climate change to have a moderate effect on their

livelihood capitals. • Score for men was 2.80 and it was 2.94 for women • Women perceived that climate change will have more effect on

livelihood capitals.• Both men and women perceived that financial capital will be

affected more than other livelihood capitals with a score of 3.16.• Women perceived that natural and human capitals will have more

effect due to climate change with a score of 2.93. • Significant difference between the perception of men and women

about potential effect of climate change with reference to livelihood capitals i.e., natural, physical and social capitals for which P value is less than 0.05.

Conclusion• Climate change affects fishing community making them

vulnerable. • Among the fishing communities, women are more

vulnerable. • This information should be applied to design climate

change interventions and programmes. • The unique vulnerabilities and needs of fishers and women

need to be mainstreamed into climate change policies. • Such mainstreaming of gender issues would help ensure

that policy and operational responses to climate change go further in terms of meeting the needs of one of the most vulnerable sectors of society.
