Main Variables of Interest in the Study
Treatment (main independent variable): The treatment variable had three levels, i.e. control group, non-CAG group and CAG group. Control slums had no CAG programme. Within the treatment slum a respondent household could either be a member of Community Action Group (labelled as ‘CAG’) or not be a member of CAG (labelled as ‘non-CAG’).
Slum household’s awareness of climate change (dependent variables): Three binary (yes/no) indicators were considered for assessing awareness of respondents about climate change. The first indicator was whether the respondent had heard of climate change or not. The second indicator on respondents’ awareness of climate change impacts was captured through an open-ended question which was converted to a binary form based on assessment of qualitative responses. From among the respondents who gave responses different from ‘don’t know’, majority of the respondents said that heat stress was increasing, followed by increase in disease incidence, flooding, pollution and water stress. The third indicator on the respondents’ general awareness of options to reduce impact of climate change was captured through another open-ended question. The responses were coded ‘yes’ if the respondent mentioned a reasonable option to reduce the impacts of climate change, and ‘no’ if the respondent said, don’t know or the response was not very coherent. The most common responses were afforestation or tree plantation, followed by. ‘over-population must be controlled’, ‘vehicle use must be reduced’, avoid the use of air conditioning, etc. Figure 22.2a presents the distribution of responses for awareness of climate change across control, non-CAG and CAG groups.
Action on climate change by slum households (dependent variables): Two indicators were considered for assessing the action of slum households in terms of adopting specific options to reduce climate risk. The first was whether the respondent had heard of specific options to reduce climate risks faced by them in the context of their slums. As part of MHT’s intervention, the Community Action Groups attempted to build capacity building of agents through communication exercises and workshops on the understanding of climate change, participatory vulnerability assessment and an exposure to set of risk reducing or adaptation options for reducing climate risks faced by the community. The sample of respondents was asked, whether they had heard of certain options to reduce the heat stress in summers due to higher temperatures, reduce the mosquito menace and reduce impact of flooding. The response options consisted of ‘heard’ of the option, ‘not heard’ of the option and ‘invested’ in the option. For some of the options, the question was asked only in the endline year, as these were technologies which had not been introduced through the intervention in the baseline year. Figures S1 and S2 (in supplementary material) present the array of such risk reducing or adaptation options in terms of the proportion of respondents who had chosen, ‘heard’ and ‘not heard’ (invested option was converted into ‘heard’ category for this piece of analysis) responses across control, Non-CAG and CAG households. The second indicator was the implementation of adaptation option(s) by slum households which was captured by looking at the actual options in which people invested their money in baseline and endline years. The endline year had more number of options in which households invested as the Community Action Groups had sensitized their members to additional options available to reduce risk (see Fig. 22.2c).
Control variables: The awareness of climate change and actual implementation of adaptation option will depend on the vulnerable situation of households in slums and adaptive capacity of households in slums as shown in the conceptual framework for the study (Fig. 22.1). The attribute of value, i.e. human health issues due to heat stress and vector-borne disease and economic effect of flooding in terms of loss of property, loss of work and loss of schooldays for child, is included in the equation as independent variable. The greater the loss in these dimensions, the greater the expectation of a household being aware of climate risk and investing in adaptation options.
Three indicators for adaptive capacity are included here. One is related to the institutions at the local level, i.e. whether a respondent is a member of a CAG or not which is also the treatment and the main independent variable in the study. The second is the income of the households which is expected to affect the ability of the slum household to implement a particular adaptation option and is also a proxy indicator of many other dimensions of adaptive capacity related to wealth. The third indicator is literacy, with the expectation that greater the literacy, the greater the awareness of climate change and agency to implement adaptation options. Also, Table 22.3 shows that the control groups and treatment groups are unbalanced with respect to these variables. Hence, including these in the regression equation as controls is reasonable.
Another covariate included in the regression equation is whether the slum belongs to cities where MHT has established operations and is experienced in implementation of community action groups for resilience building in slums (like Ahmedabad) and cities where their operations are new and emergent (like Bhopal, Jaipur and Ranchi) to account for city fixed effects.
Effect of Community Action Groups on Awareness Climate Change and Implementation of Adaptation Options
For each outcome (dependent variable), Fig. 22.3 displays (i) the DID estimate and (ii) robust clustered standard errors of the DID estimate. The complete results of DID regression with all its covariates are available in the supplementary material as Table S2.
The DID estimates suggest that membership of Community Action Groups had a significant effect on two out of three indicators of awareness of climate change. The effect of treatment was not significant for whether the respondent had heard of climate change in the CAG group. This is because as Fig. 22.2a shows that awareness of climate change was already high among the CAG members in the intervention slums in the baseline year (probably, because MHT already had a presence in the established city (Ahmedabad) slums even before the intervention). The MHT’s intervention and facilitation in these slums had included discussions on climate change even previous to the start of the Global Resilience Project. This is validated by some qualitative comments of respondents in the baseline year, when they were asked, ‘Where have you heard or learned about climate change?’ Majority of the respondents said that they learnt about climate change from MHT meetings. The interesting result is that even among respondents who are not members of CAG, but part of treatment slums, there is a significantly higher awareness of climate change. There seem to be spillover effects of knowledge from CAG to non-CAGs in the same treatment slum communities whereas control groups are in slum different communities with no treatment at all.
The DID estimates for awareness about specific adaptation options and implementation of adaptation actions are not significant if we include all thirteen specific adaptation options in the dependent variable. This seems counterintuitive as Figs. S1 and S2 (in supplementary material) show that for many adaptation options there seems to be a significant difference between awareness of specific adaptation options in baseline period and endline period. Delving deeper into the data, we found that the number of respondents who had adopted ‘mosquito nets’ and ‘mosquito screens’, and implemented more ‘windows for ventilation’ were quite large in the endline year and across not just non-CAG and CAG groups but also control group (see Tables S3 and S4 in supplementary material). The relatively large number in control group for the above three options was masking the effect of intervention on awareness and implementation of other specific adaptation options. Also, the option of construction of plinth for reducing flood risk is greater among CAG households in baseline year compared to intervention year (see Table S3 in supplementary material). Hence, we excluded the mosquito nets and screens and more windows for ventilation and construction of plinth in computing the dependent variables—‘awareness of specific adaptation options’ and ‘implementation of specific adaptation options’.
After this, we found the effect of the intervention to be significant not only for CAG group but also for the non-CAG group, again implying positive spillover or externalities of the intervention in the treatment slums. Moreover, the effect on non-CAG group seems to be bigger in case of some dependent variables as the change in non-CAG group from baseline to endline year is a bigger change compared to the change in CAG group from baseline to endline years (the bar plots show, in many instances, in the baseline situation, the non-CAG is at a much lower level than CAG). A probable cause of more people in the control group becoming more aware of and implementing these three specific options could be the sensitization during baseline year through the questionnaire interview. Since these are commonly understood options and relatively easy to implement, we see a greater awareness and implementation of these across all three groups, irrespective of the treatment.
Though the effectiveness of CAGs to enhance the awareness of climate change, and implementation of adaptation options by slum households to reduce climate impacts and risks is established by the empirical evidence in this paper, however, the efficacy of CAGs to do the above is not perfect as is discussed in the next section.
Impact of Heterogeneities Within Treatment Group on the Effect of Treatment
From Fig. 22.2a and Figs. S1 and S2 (in supplementary material), it is evident that in none of the plots of climate change awareness and awareness of specific adaptation options, the proportion of CAG members who are aware of climate change or of the adaptation options is greater than 75%. This means, that at least 25% of members of CAG have either not heard of climate change and specific adaptation options or could not recall it when asked about it. There could be many reasons for this—one, that not all members necessarily attend all CAG meetings and its training programmes. The members who miss the meeting and/or training programmes naturally have lost the opportunity to learn about these issues. A second reason could be that some of the members may not comprehend fully the notions of climate change and different types of adaptation options due to lack of capacities such as education and income.
Hence, for the sample of CAG respondents only (n = 281), Table 22.4 presents an OLS regression with dependent variable being the number of specific adaptation options that a household had ‘heard’ of. The independent variables are three socio-economic indicators of capacity, i.e. being above or below BPL, literacy and house type. Literacy is positively correlated with whether a person heard of or had not heard of adaptation options to reduce heat stress and vector-borne diseases. Hence, lack of education could be a barrier in comprehending and understanding fully the various adaptation options. Similarly, people living in kuccha houses are less likely to have heard of adaptation options.
Table 22.4 Determinants of a CAG group respondent having ‘heard’ of a specific adaptation option The implication of this result is that even though CAGs by definition seem to be inclusive and participatory, but even at such a decentralized level, heterogeneities in demographic and socio-economic conditions of members may mean exclusion of certain members from full and complete participation.
Community Action Group Membership and Engagement with Local Government
One of the objectives of the CAGs facilitated by MHT is to improve the ability of the women to collectively to engage with local governments in co-creating and implementing solutions to the problems that slum dwellers face. The qualitative interviews with CAG members do point to this. However, the quantitative data, which has been the focus of analysis in this paper, did not include many variables which could tap into this dimension (ability to engage with local governments) of capacity enhancement of slum households and communities. We could find only one variable in the data set that reflected this dimension—which was whether the respondent household had approached the health department to address the mosquito problem in the endline survey (see Fig. 22.4 for results).
We find that a very small proportion of respondents answered in the affirmative to this question across all the respondent categories, i.e. CAG, Non-CAG and control group. However, the odds of CAG respondents approaching the health department to address the mosquito problem was at least four times the odds of a control group respondent doing so (see Table S5 in supplementary material).
