The aim of quantitative research is to examine the influence of in- come level on the citizen preparedness for response to a natural disaster caused by flood in the Republic of Serbia. Bearing in mind all local communities in Serbia where occurred or there is a high risk of flood occurrence, nineteen of 150 municipalities and 23 cities and the city of Belgrade were randomly chosen. In selected communities the research was performed in those areas that were most affected in relation to the water level or potential risk. The survey applied test strategy in house- holds with the use of a multi-stage random sample. The research results indicated that the citizens who had income above RSD 90,000 at the household level, in a higher percentage took preventive measures, they know what floods are and know the safety procedures. On the other hand, citizens who have income below RSD 25,000 are not yet prepared, or intend to take certain measures in the next 6 months. The originality of the research stems from the fact of unexamined influence of income level on citizen preparedness. The research results can be used when creating strategies to improve the preparedness of citizens for response. The originality of the research is reflected in the fact that Serbia has not ex- amined the influence of income level on preparedness of citizens to re- spond. The results can be used when creating a strategy to improve the level of citizen preparedness for response with regard to the level of citi-

zen incomes.

Introduction

Income realized by one household is an important factor when making decisions on the adoption of certain measures of preparedness for response to natural disasters.

The results of national research in the United States (FEMA, 2009), indicate that unem- ployed citizens (47%) to a greater extent rely on the help of emergency-rescue services in relation to employees (31%); employed people to a greater extent (69%) believe that

100 taking measures of preparedness, planning and acquisition of supplies will help them in natural disasters; also, they to a greater extent feel that improvement of preparedness will help them to deal with the consequences of natural disasters; Citizens with lower incomes to a greater extent rely on the competent authorities, they need help with evacuation or going to the shelter compared to households with higher incomes; unem- ployed citizens (45%) to a greater extent rely on the help of other citizens compared to employees (34%); citizens with lower incomes to a greater extent believe they could be affected by a natural disaster in the next 12 months; people with higher incomes to a greater extent believe that taking measures of preparedness, planning and acquisition of supplies will help them in natural disasters; furthermore, they are more confident in their abilities to cope with consequences of natural disaster; citizens with lower incomes to a greater extent, do nothing to raise the level of preparedness to a higher level; house- holds with lower incomes to a greater extent were prepared in the past 6 months com- pared to households that earn more.

Various researches in the US suggest: people with higher incomes to a lesser extent, indicate that such measures are costly as a reason for not taking measures of prepared- ness and scored a higher level of preparedness to respond to disasters (CEG, 2006); furthermore, people with lower incomes (54%) are less prepared to respond and attend training, compared to citizens with higher incomes (61%). At the level of significance of 5% Baker (Baker, 2011) found that there is a significant statistical relationship between household income and the level of preparedness for response to a hurricane (χ2 = 41.74, df = 4, p = 0.001 < 0.05). In a survey conducted in the United States, full-time employees showed a higher level of preparedness for response, especially emphasizing that their education and training conducted at work mean a lot for them (CEG, 2006).

In the literature, there is no generally accepted definition of preparedness for re- sponse to natural disasters (Cvetković, 2015abv; Ostojić, 2014; Vratuša-Žunjić, 2001). After all, it can easily get the impression that the determination of the content and scope of the term is somewhat marginalized (Cvetković, Gačić, & Jakovljević, 2015). Prepared- ness as a concept in the theory of disasters includes activities undertaken before natural disasters in order to improve the response and recovery from the resulting conse- quences (Cvetković, 2015; Gillespie et al. 1993: 36). Tierney et al (Tierney, Lindell, & Perry, 2002: 27) suggest that preparedness includes activities undertaken to strengthen the capabilities and opportunities of social groups to respond to situations caused by disasters. Thereby, they emphasize the inconsistency of preparedness with a clear focus on its two objectives: 1. to help people to avoid the threat; 2. to develop capacities and mechanisms with the aim of an effective response to disasters.

Methodology and data

Study design

Operationalization of the theoretical notion of preparedness to respond has given three dimensions that have been studied by identification of larger number of variables for each one (Figure 1). Perception of preparedness includes variables on preparedness

at different levels; barriers for raising the level of preparedness; variables on the expectation on help from different categories of people and organizations; assessment of effectiveness of first responders to respond. Knowledge was examined through variables related to the level of knowledge; flood risk map; knowing where they are and how to use them, willingness to train, willingness for methods of education, way to obtain the information about floods. And the third dimensions, supplies relate to having oral/written plans, having supplies of food and water, a transistor radio, flashlight, hoe, shovel, hoe and spade, first aid kit, insurance.

Sample

The population consists of all adult residents of local communities in which there is a risk to occur flash flood or flood caused by dam failure. The sample size has been adjusted with the geographical (local communities from all regions of Serbia will be represented) and demographic size of the communities themselves. It was randomly selected sample of 19 of 150 municipalities and 23 towns and the city of Belgrade (Table 1 and Figure 2).

The research was undertaken in those areas that were most affected related to the amount of water or potential risk. In the survey, questioning strategy was applied to households with the use of a multi-stage random sample. In the first step, which refers to the primary causal units, parts of community in the research were selected. This process was accompanied by creation of map and determination of percentage share of each such segment in the total sample. In the second stage, streets or sections of streets were determined on the level of primary causal units. Each research core was determined as the path with specified start and end points of movement. In the next step, households in which the survey would be conducted were defined. The number of households is harmonized with population count of community. The final step referred to selection of respondents within households previously defined. The selection of respondents was conducted following the procedure of next birthday for adult members of household. The process of interviewing for each local authority was held three days in a week (including weekends) at different times of days. The study surveyed with 2,500 persons.

Similar as in the entire population, the sample has more women (50.2%) than men (49.8%). In 2014, the average age of respondents was 39.95 (men 40.9 and women 38.61). Observing the educational structure of citizens who are included in the sample, it also can be noted that majority of population (41.3%) has secondary/four years school. The smallest percentage of population has completed master (2.9%) and doctoral studies (0.4%). Marital status can be viewed from the aspect of legal marital status and factual marital status which also includes persons living in extramarital community. In the sample, married people account to 54.6%, widow/widower 3%, unmarried (single) 18.8%, engaged 2.7% and in relationship 16.9%.

Instrument

For validity and reliablity studies of the data gathering instrument five steps were taken. In the first step, we determined some scales used for measuring the preparedness of citizens to respond to disasters in general or to specific natural disaster. The third step included the aforementioned operacionalization of preparedness for response and deciding on the three basic dimensions (perception of preparedness to respond, knowledge and supplies). In the fourth step, we defined variables for each dimension (perceptions of preparedness to respond – 46 variables; knowledge – 50 and supplies – 18), then for each variable it was taken, adapted or specially designed question in instrument. The fifth and final step it was carried out preliminary (pilot) study in Batočina with the aim of checking constructed instrument (its internal compliance of the scale, i.e. degree of relatedness of items of which it is composed, and whether instructions, questions and values on scale are clear).

Data analysis

Statistical analysis of collected data was performed by IBM’s software package SPSS. Chi-square test of independence (χ2) was used for testing of the connection between gender and categorical variables on perception, knowledge and having supplies and plans for a natural disaster caused by flood. On that occasion additional assumptions were completed about minimum expected frequency in each cell, which amounted to five or more. Assessment of impact level was performed by phi coefficient representing the correlation coefficient ranging from 0 to 1, where a higher number indicates a stronger relationship between the two variables. Koen criteria were used: from 0.10 for small, 0.30 for medium and 0.50 for large effect. For tables larger than 2 by 2, to assess the impact level it was used Cramer’s V coefficient which takes into account the number of degrees of freedom (Cohen, 1988). Accordingly, for R-1 or K-1 is equal to 1, we used the following criteria of impact size: small = 0.01, medium = 0.30 and large = 0.50. To test the connection between gender and continuous dependent variables on the perception, knowledge and having supplies and plans for natural disasters caused by floods, it was selected independent samples t-test. Before proceeding to the implementation of the test, we examined general and specific assumptions for its implementation.

Results and Discussion

The results of Chi-square test of independence (χ2) showed a statistically significant relationship between income level and the following variables: preventive measures (p = 0.000 < 0.05, v = 0.080 – small influence); financial resources (p = 0.000 < 0.05, v = 0.143 – small influence); engaged in the field (p = 0.004 < 0.05, v = 0,083 – small influence); river level rise (p = 0.000 < 0.05, v = 0.115 – small influence); preparedness level (p = 0.000 < 0.05, v = 0.115 – small influence). On the other hand, there was no

statistically significant relationship with variables: engaged in shelters (p = 0.459 > 0.05), visiting flooded areas (p = 0.463 > 0.05), heavy rains (p = 0.111 > 0.05) and media reports (p = 0.429 < 0.05) (Table 3). Based on results:

  • In the highest percentage: citizens with household incomes over RSD 90,000 (24.9%) have undertaken preventive measures, would give money to help victims affected by floods (47.3%), water level rise makes them to think about preparedness (42.9%), have recently started preparations (11.1%) and they have prepared for at least

    6 months (5.3%); people with household incomes up to RSD 50,000 (20.7%) would engage in providing assistance to victims in the field; people with household incomes up to RSD 25,000 are still not prepared, are intend to take measures in the next 6 months (17.9%) are still not prepared, but will start preparing in next month (13.3%);

  • On the other hand, in the lowest percentage: citizens with household incomes up to RSD 25,000 (11.9%) have undertaken preventive measures, would give money to help victims affected by floods (23.8%), would engage in providing assistance to victims in the field (13.5%), water level rise makes them to think about preparedness (30.9%), they have prepared at least past 6 months (2.1%), and do nothing to prepare for response to floods (52.7%).

    Using one-way analysis of variance (one-way ANOVA) it was studied the influence of income level of citizens on dependent continuous variables on the perception of preparedness to respond. Subjects were divided by income level into 4 groups (up to RSD 25,000, up to RSD 50,000, up to RSD 75,000 and over RSD 90,000). Using the homogeneity of variance test it was examined equality of variances in the results for each of the 4 groups. Bearing in mind the results Levene Statistic, the assumption of homogeneity of variance is not violated in the following variables: household preparedness; personal skills; ISS; religious communities; self-organized individuals; citizens from flooded areas; and efficiency of the police. For variable in which the assumption is violated, it was shown in table “Robust Tests of Equality of Means” and the results of two tests, Welsh and Brown – Forsythe tests resistant to a violation of the presumption of equality of variances. For research purposes, Welsh’s results are used.

    Based on results, there is a statistically significant difference between the mean values of those groups in the following continuous dependent variables: household preparedness (F = 4.11, p = .006, eta squared = 0.0052 – small influence); importance of taking preventive measures (F = 27.70, p = .000, eta squared = 0.0348 – small influence); ISS (F = 4.43, p = .004, eta squared = 0.0058 – small influence); I have no time for that (F = 9.28, p = .000, eta squared = 0.0121 – small influence); it is very expensive (F = 3.07, p = 0.006, eta squared = 0.0040 – small influence); I have no support (F = 4.34, p = .005, eta squared = 0,0057 – small influence); NHO (F = 5.73, p = .001, eta squared = 0,0075 – small influence); police (F = 4.91, p = .002, eta squared = 0.0064 – small influence); first responders (F = 6.46, p = .000, eta squared = 0.0084 – small influence); army (F = 9.14, p = 0.000, eta squared = 0.0118 – small influence); help would not mean much (F = 6.49, p = 0.000, eta squared = 0.0088 – small influence); preparedness of local communities (F = 4.34, p = .005, eta squared = 0.0055 – small influence); national preparedness (F = 4.00, p = 0.008, eta squared = 0.0049 – small influence) personal abilities (F = 7.06, p = 0.000, eta squared = 0.0091 – small influence); I can not prevent it (F = 2.92, p = 0.033, eta squared = 0.00393 – small influence); household members (F = 8.47, p = 0.000, eta squared = 0.00987 – small influence); neighbors (F = 9.64, p = 0.000, eta squared = 0.0114 – small influence); MHO (F = 5.42, p = .001, eta squared = 0,0074 – small influence); religious communities (F = 8.62, p = 0.000, eta squared = 0.0114 – small influence); emergency service (F = 3.59, p = .013, eta squared = 0.0046 – small influence); awareness (F = 11.963, p = .000, eta squared

    = 0.0161 – small influence); others helped (F = 3.93, p = 0.008, eta squared = 0.00513 –

    small influence); duty of state authorities (F = 4.69, p = 0.003, eta squared = 0.0065 – small influence); citizens of flooded areas (F = 3.52, p = .015, eta squared = 0.0049 – small influence); it is too expensive (F = 13.81, p = 0.000, eta squared = 0.0179 – small influence); police efficiency (F = 8.27, p = 0.000, eta squared = 0.0100 – small influence); efficiency of first responders (F = 9.81, p = 0.000, eta squared = 0.0125 – small influence); efficiency of emergency service (F = 11.45, p = 0.000, eta squared = 0.0160 – small influence); army efficiency (F = 7.58, p = 0.000, eta squared = 0.0097 – small influence) (Table 4).

    Subsequent comparisons using Turkey HSD show that the observed mean value:

Relationship between income level

The results of Chi-square test of independence (χ2) showed a statistically significant relationship between income level and the following variables on knowledge: familiarity with safety procedures (p = 0.006 < 0.05, v = 0.065 – small influence); evacuation (p = 0.000 < 0.05, v = 0.106 – small influence); education at school (p = 0.000 < 0.05, v = 0.084 – small influence); education at work (p = 0.000 < 0.05, v = 0.103 – small influence); elders, disabled (p = 0.023 < 0.05, v = 0,058 – small influence); consent to evacuation (p = 0.000 < 0.05, v = 0.098 – small influence); help – elders, disabled (p = 0.009 < 0.05, v = 0.098 – small influence); neighbors – individually (p = 0.000 < 0.05, v = 0.109 – small influence); flood risk map (p = 0.000 < 0.05, v = 0,102 – small influence); official warning (p = 0.000 < 0.05, v = 0,101 – small influence); potential infections (p = 0.050 < 0.05, v = 0,059 – small influence); water valve (p = 0.003 < 0.05, v = 0.073 – small influence); electricity switch (p = 0.013 < 0.05, v = 0,061 – small influence); information from neighbors (p = 0.003 < 0.05, v = 0.080 – small influence); information from a friend (p = 0.000 < 0.05, v = 0.111 – small influence); information from relatives (p = 0.009 < 0.05, v = 0.073 – small influence); information at school (p = 0.022 < 0.05, v = 0.066 – small influence); information in collage (p = 0.000 < 0.05, v = 0.162 – small influence); information on the radio (p = 0.015 < 0.05, v = 0.069 – small influence); information from the press (p = 0.003 < 0.05, v = 0.080 – small influence); information over the Internet (p = 0.000 < 0.05, v = 0.138 – small influence); trained (p = 0.007 < 0.05, v = 0.079 – small influence); desire for training (p = 0.000 < 0.05, v = 0.119 – small influence); education. on television (p = 0.000 < 0.05, v = 0.138 – small influence); education on the radio (p = 0.007 < 0.05, v = 0.079 – small influence); education through the Internet (p = 0.000 < 0.05, v = 0.122 – small influence); education through lectures (p = 0.000 < 0.05, v = 0,145 – small influence). On the other hand, there was no statistically significant relationship with variables: education within the family (p = 0.073 > 0.05), gas valve (p = 0.274 > 0.05), handling water valve (p = 0.602 > 0.05), handling gas valve (p = 0.274 > 0.05), handling electricity switch (p = 0.132 > 0.05), information from household members (p = 0.192 > 0.05), information through an informal system (p = 0.321 > 0.05), information at work (p = 0.079 > 0.05), information in a religious community (p = 0.471 > 0.05), information on television (p = 0.134> 0.05), education through video – games (p = 0.267 > 0.05), informal system (p = 0.878 > 0.05) (Table 5).

    * Statistically significant correlation – p ≤ 0.05

    Using one-way analysis of variances (one-way ANOVA) it was studied the influence of the incomes of citizens on dependent continuous variables on knowledge for response. Subjects were divided into 4 groups by income level (up to RSD 25,000, up to RSD 50,000, up to 75,000 and over RSD 90,000). Using the homogeneity of variance test it was examined equality of variances in the results for each of the 4 groups. Bearing in mind the results of Levene Statistic, the assumption of homogeneity of variance is not violated in the variable: nearby shelters. For variable in which the assumption is violated, it is presented in table ”Robust Tests of Equality of Means” and the results of two tests, Welsh and Brown-Forsythe tests resistant to the violation of the assumption of the equality of variances. For the study purposes, the findings of Welsh test are used.

    Based on results, there is a statistically significant difference between the mean values of those groups in the following continuous dependent variables of knowledge: knowledge level (F = 4.17, p = .006, eta squared = 0.0054 – small influence); possibility of flooding – 1 year (F = 3.11, p = .026, eta squared = 0.00367 – small influence); possibility of flooding – 5 years (F = 3.944, p = .008, eta squared = 0.0045 – small influence); warning systems (F = 13.54, p = 0.000, eta squared = 0.0165 – small influence); police (F = 18.59, p = .000, eta squared = 0.0218 – a small effect); first responders (F = 18.241, p = .000, eta squared

    = 0.0219 – small influence); Stuff for emergency situations (F = 21.09, p = .000, eta squared

    = 0.0263 – small influence); evacuation routes (F = 6.907, p = 0.000, eta squared = 0.0091 – small influence) (Table 6).

    Subsequent comparisons using Tukey HSD show that the observed mean value:

  • Assessment of food risk of local community in the next 5 years, statistically significantly (p < 0.05) and mutually differs among the citizens with household incomes below RSD 25,000 (M = 2.61, SD = 1.435) and citizens with incomes over RSD 90,000 (M = 2.30, SD = 1.275). Citizens with incomes up to RSD 25,000 to a greater extent, assess flood risk compared to citizens with incomes over RSD 90,000;
  • Assessment of food risk of local community in the next 5 years, statistically significantly (p < 0.05), and mutually differs among the citizens with household incomes below RSD 75,000 (M = 2.90, SD = 1.317) and citizens with incomes over RSD 90,000 (M = 2.54, SD = 1.274). Citizens with incomes up to RSD 75,000 to a greater extent, assess flood risk compared to citizens with incomes over RSD 90,000;
  • familiarity with warning system in the local community for natural disasters statistically significantly (p < 0.05), and mutually differs among the citizens with household incomes up to RSD 25,000 (M = 2.09, SD = 1.154) and citizens with incomes up to RSD 75,000 (M = 2.53, SD = 1.127). Citizens with incomes up to RSD 25,000 to a lesser extent, assess flood risk compared to citizens with income up to RSD 75,000;
  • familiarity with police jurisdiction statistically significantly (p < 0.05), and mutually differs among the citizens with household incomes below RSD 25,000 (M = 2.46, SD = 1.276) and citizens with incomes below RSD 75,000 (M = 2.95, SD = 1.132). Citizens with incomes up to RSD 25,000 to a lesser extent are familiar with police jurisdiction compared to citizens with incomes up to RSD 75,000;
  • familiarity with competencies of first responders statistically significantly (p < 0.05), and mutually differs among the citizens with household incomes up to RSD 25,000 (M = 2.57, SD = 1.290) and citizens with incomes up to RSD 75,000 (M = 3.10, SD = 1.176). Citizens with incomes up to RSD 25,000 to a lesser extent are familiar with jurisdiction of first responders compared to citizens with incomes over RSD 90,000;
  • familiarity with competencies of stuff for emergency situations statistically significantly (p < 0.05), and mutually differs among the citizens with household incomes up to RSD 25,000 (M = 2.40, SD = 1.227) and citizens with incomes up to RSD 75,000 (M = 2.97, SD = 1.236). Citizens with incomes up to RSD 25.000 to a lesser extent are familiar jurisdiction of stuff for emergency situations compared to the citizens with incomes up to RSD 75,000;
  • familiarity with evacuation routes statistically significantly (p <0.05) and mutually differs among the citizens with household incomes below RSD 25,000 (M = 2.27, SD = 1.269) and citizens with incomes below RSD 75,000 (M = 2, 59, SD = 1.415). Citizens with incomes up to RSD 25,000 to a lesser extent know the routes for evacuation compared to citizens with incomes up to RSD 75,000;
  • familiarity with risk assessment and plan of protection and rescue from the consequences of floods statistically significantly (p < 0.05), and mutually differs among the citizens with household incomes below RSD 25,000 (M = 2.27, SD = 1.201) and citizens with incomes up to RSD 75,000 (M = 3.02, SD = 1.179). Citizens with incomes up to RSD 25,000 to a lesser extent are familiar with risk assessment and plans for protection and rescue compared to citizens with incomes up to RSD 75,000.

    and possession of supplies and plans

     

    Relationship between income levels

    The results of Chi-square test of independence (χ2) showed a statistically significant relationship between income level and the following variables on supplies and plans: supplies at home (p = 0.020 < 0.05, v = 0,063 – small influence); food supply (p = 0.031 < 0.05, v = 0.099 – small influence); water supply (p = 0.027 < 0.05, v = 0.104 – small influence); radio-transistor (p = 0.000 < 0.05, v = 0,145 – small influence); flashlight (p = 0.020 < 0.05, v = 0.091 – small influence); shovel (p = 0.021 <0.05, v = 0.091 – small influence); hack (p = 0.021 < 0.05, v = 0.091 – small influence); hoe and spade (p = 0.006 < 0.05, v = 0.143 – small influence); apparatus for firefighting (p = 0.002 < 0.05, v = 0.116 – small influence); restocking (p = 0.005 < 0.05, v = 0,087 – small influence); supplies in the car (p = 0.000 < 0.05, v = 0.074 – small influence); first aid kit in the home (p = 0.000 < 0.05, v = 0,087 – small influence); first aid kit in the vehicle (p = 0.000 < 0.05, v = 0.128 – small influence); first aid kit – easily accessible (p = 0.000 < 0.05, v = 0.084 – small influence); discussion on the plan (p = <0.05, v = 0, – small influence); copies of documents (p = 0.01 < 0.05, v = 0,063 – small influence). On the other hand, there was no statistically significant relationship with variables: plan for response (p = 0.207 > 0.05); and insurance (p = 0.088 > 0.05) (Table 7).

    Based on results, in the highest percentage:

  • Citizens with household incomes over RSD 90,000, have supplies (36%), food supplies for four days (68.5%), water supply for four days (52%), radio-transistor (33.3%), flashlight (50.5%), shovel (54.8%), hack (39.8%), hoe (54.4%), apparatus for firefighting (11.3%), supplies in the car (7,3%), first aid kit at home (70.6%), in the vehicle (41%), first aid kit in an easily accessible place (73.1%), discussion on plan for response with household members (25.9 %), once a month (44%), once a year (26.6%) replenish supplies, keep copies of important personal, financial and insurance documents in a safe place (33.8%), have a water supply for two days (24 %);
  • Citizens with household incomes up to RSD 75,000 have food supplies for two days (21.7%), water supplies for one day (11.9%), have water supplies for two days (37.3%);
  • Citizens with household incomes up to RSD 50,000 have never replenished supplies (50.6%);
  • Citizens household incomes up to RSD 25,000 have food supplies for one day (19.8%), water supplies for one day (25.4%).

    On the other hand, in the smallest percentage:

  • Citizens with household incomes up to RSD 75,000 have supplies (22.9%), food supplies for one day (12,3,8%), one a month (26.7%) and have never (50.6%) replenished kept supplies;
  • Citizens with household incomes up to RSD 25,000 have food supplies for two days (13.2%) to water supplies for four days (40.7%), have a radio-transistor (15.9%) and flashlight (36.1%), hack (23.5%), apparatus for firefighting (27.3%), first aid kit at home (47.5%), first aid kit in the vehicle (38%), first aid kit in an easily accessible place (21%), discussion on plan for response to with household members (13.6%), keep copies of important personal, financial and insurance documents in a safe place (33.8%);
  • Citizens with household incomes up to RSD 50,000 have supplies for four days (57%); have a shovel (38.4%), hoe (29.8%) and supplies in the car (4.8%).

Recommendations for improving preparedness of citizens

It should influence on citizens who have incomes up to RSD 25,000: to take measures of preparedness to respond, to deposit funds to help people threatened by floods, to get engaged in assisting flood victims in the field, to take measures of preparedness encouraged by displaying images or recordings of raising water, to raise the level of confidence in their own abilities by additional education or specific training. They should be informed about the competencies of the police, first responders and staff for emergency situations during natural disasters caused by floods. They need to be informed about the evacuation routes and nearby shelters. They should be encouraged to acquire food supplies for two days, flashlight, hack, apparatus for fire fighting, first aid kit and to discuss on how to react. Citizens with incomes up to RSD 90,000 should be influenced to evacuate in emergency situations to neighbors’ places and rented apartments if needed. They should be educated about where water valve is located. Education has to be made through the radio, the internet, and non-formal education system. Citizens with household incomes up to RSD 75,000 should be influenced primarily through education about what flooding is and how to react in such situations. They should be encouraged to be educated about what they should do after official warnings about the approach of the flood and where switch for electricity is located. Citizens with incomes up to RSD 50,000 need to be learned about viruses and infections that accompany the period after floods and encouraged to undergo specific training in handling such situations. Citizens with incomes up to RSD 75,000 should be encouraged to acquire food supplies at least for one day, and to replenish them once a month.
