Types of Data Collected

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.

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.

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.

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.

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.

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.

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.

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.
