2.1. Types of Data Collected

Here is the level of people different kind of stakeholders starting from our GCOE that is global centre of excellence, human security engineering of Kyoto university team and Local community members and municipal corporations Greater Mumbai especially the involvement of the G-North wards, like we help them in mapping and I say, we also work as the surveyors, and explaining and introducing community the role and objective of the survey.

In this chunk, we see that various stakeholders played crucial roles in the data collection process. The stakeholders include the Global Centre of Excellence (GCOE), experts from Kyoto University with a focus on human security engineering, local community members, and representatives from municipal corporations in Greater Mumbai. The G-North wards are highlighted as particularly involved areas where the team assists in mapping. The involvement of these diverse groups is essential to explain the survey's purpose and the role each party plays in the data collection endeavor.

Think of it like a community project where everyone comes together to build a playground. You have engineers (the GCOE), parents from the neighborhood (local community members), and city officials (municipal corporations) all working together. Each group brings something unique; engineers design the playground, parents help fund it, and officials ensure it meets safety standards.

We collected a lot of data there starting from land-use data, residential, commercial, public, playground, infrastructure what are the infrastructures are there, Doctors clinic, community toilet, community taps, school.

This chunk summarizes the types of data collected during the survey. It includes land-use data, which is essential for understanding how land is being utilized in the community. This includes different categories like residential areas, commercial spaces, public parks, and infrastructure such as clinics, toilets, taps, and schools. Gathering this wide range of information is vital to assess the community's needs and identify resources effectively.

Imagine you are a city planner trying to improve your town's services. You would need to know where houses are located, how many shops exist, if there are parks for kids to play in, and if there are enough healthcare facilities. Gathering all this data is like creating a detailed map of resources you can use to make decisions about where to build new facilities.

Hazard parameters we considered, flood duration, water level during the flood, areas frequently affected, building height, building materials, building conditions, plinth level these all we collected.

In this part, the discussion focuses on the hazard parameters collected as part of the survey. These parameters include critical factors like flood duration, the water level reached during floods, and areas that are frequently affected by flooding. Other considerations include the height and materials of buildings, their physical conditions, and the plinth level—how high buildings are constructed above the ground. This information is crucial for understanding the risks communities face and ensuring informed decision-making in disaster management and urban planning.

Think of it like preparing for a sports event. Coaches need to know how long the rain will last (flood duration), how deep puddles might get (water level), which players are likely to slip (areas frequently affected), and how sturdy the field is (building materials). All this information helps them prepare for any challenges that might affect their team's performance.

Now here are some of the facts that in 2006 after 2006 lot of residential areas this is actually a road this is one of the fraction of the Rajiv Gandhi Nagar, many are transferred into commercial areas.

This chunk discusses changes in land use patterns observed after 2006, specifically in Rajiv Gandhi Nagar. It notes that many residential areas have been transformed into commercial spaces. Understanding how land use evolves is important as it can impact community dynamics, resource allocation, and urban planning strategies. Such changes often reflect socioeconomic shifts and growth in commerce, requiring adjustments in infrastructure and services.

Imagine a quiet neighborhood where families used to live, but over time, new shops and restaurants opened up throughout the area, turning it into a bustling commercial hub. This change can change how traffic flows, where people work, and what services are needed, similar to how a quiet street can become a busy shopping district.

People started to build G+1 structure in though this is not allowed, but community allowed that community reported that many people are now constructing G+1 structure in Rajiv Gandhi Nagar okay.

This segment highlights a concerning trend where residents in Rajiv Gandhi Nagar have begun to construct unauthorized G+1 structures, meaning buildings that are designed to have one additional floor, despite regulations against it. Community members reported this phenomenon. Understanding local building practices is essential for assessing risk and safety, especially in areas prone to flooding or other hazards.

Think of a student who sneaks in a snack to school despite the rules. Even though there’s a clear rule against it, the student might feel it's okay because everyone else is doing the same. Similarly, as more residents see their neighbors building extra floors, they might feel encouraged to do the same, disregarding the risks it could pose.

Also the electricity supply; it can easily electrified, and current can kill people during emergency or flood inundations.

This chunk addresses serious infrastructure concerns, particularly regarding electricity supply in flood-prone areas. It states that electrical systems can become dangerous during emergencies like floods, with the potential for electrical currents to cause harm or fatalities. Ensuring robust and flood-resistant infrastructure is vital for community safety, especially in vulnerable areas.

Consider the importance of having safety measures in place for your home during a storm. Just like how you would worry about water damaging your electronics or electrical wiring during a heavy rain, communities need to ensure their electrical systems are protected from floodwaters to prevent dangerous situations.

Access roads are very narrow; you cannot evacuate, two people cannot pass easily from this one.

This part emphasizes the challenges posed by narrow access roads in emergency situations. When roads are too narrow, it can be difficult for people to evacuate, as they cannot move quickly or safely. This is particularly dangerous during floods when timely evacuation is crucial. Analyzing the physical layout of roads and their capacity to handle emergency situations is essential for effective disaster response planning.

Imagine trying to leave a crowded concert through a single narrow exit. It becomes chaotic, and people may struggle to get out safely. Similarly, when emergencies occur, narrow roads can become bottlenecks that prevent quick evacuations, putting lives at risk.

People could not evacuate during 2005 one reason that there was no designated place there was no early warning and the head of the household was not at house.

In this chunk, it describes the challenges faced by residents during a major flood event in 2005. Key issues included the absence of designated evacuation places, lack of early warning systems, and family dynamics where heads of households were not present to lead evacuations. These factors contributed to difficulties in safely evacuating during the flood, highlighting the need for better preparedness and community awareness.

Think about the importance of having a fire drill in a school. If students know where to go and what to do when a fire alarm sounds, they can evacuate quickly and safely. In a flood situation, having clear plans and designated places can save lives, just as emergency preparation in schools helps keep students safe.
