The global dimensions of disaster

Disasters are not merely natural occurrences but complex interactions between natural hazards and human vulnerabilities. To effectively address disaster risk, we must consider several interconnected dimensions:

1. Vulnerability:

Definition: The susceptibility of individuals, communities, or assets to harm from a disaster.
Factors: Socioeconomic conditions, geographic location, and environmental factors influence vulnerability.
Example: Communities with high poverty rates and limited access to resources are more vulnerable to disaster impacts.

2. Exposure:

Definition: The degree to which people, property, and infrastructure are located in hazard-prone areas.
Factors: Population density, land use patterns, and infrastructure development influence exposure.
Example: Coastal cities with high population density are highly exposed to hurricane and tsunami risks.

3. Capacity:

Definition: A community's ability to prepare for, respond to, and recover from disasters.
Factors: Strong governance, early warning systems, resilient infrastructure, and community preparedness contribute to capacity.
Example: Countries with well-developed disaster management systems and resilient infrastructure can recover more quickly from disasters.

4. Hazard Characteristics:

Definition: The nature, intensity, frequency, and duration of a hazard.
Factors: Climate change, tectonic activity, and human activities can influence hazard characteristics.
Example: Increasing frequency and intensity of extreme weather events due to climate change pose significant risks to communities.

5. Data and Information Management:

Definition: The collection, analysis, and dissemination of data to inform decision-making and improve disaster response.
Factors: Advanced technologies, effective communication systems, and data-driven approaches are crucial.
Example: Early warning systems rely on real-time data to alert communities of impending hazards.

6. Governance:

Definition: The institutional framework that coordinates disaster risk reduction efforts.
Factors: Strong leadership, effective policies, and public-private partnerships are essential.
Example: Well-governed countries with transparent and accountable institutions are better equipped to manage disaster risks.

The Disaster Risk Equation

The interplay of these dimensions can be encapsulated in a simple equation:

Risk = Hazard x Vulnerability x Exposure / Capacity

By reducing vulnerability, exposure, and enhancing capacity, we can significantly mitigate disaster risk.

The Sendai Framework

The Sendai Framework for Disaster Risk Reduction 2015-2030 provides a global blueprint for building resilient societies. It emphasizes:

Reducing exposure and vulnerability through sustainable development.
Strengthening governance to improve coordination and decision-making.
Improving resilience and adaptive capacity to enhance community preparedness and response.

History of GIS

1. 1832 - Early Spatial Analysis in Epidemiology: - Charles Picquet creates a map in Paris detailing cholera deaths per 1,000 inhabitants. - Utilizes halftone color gradients for visual representation. 2. 1854 - John Snow's Cholera Outbreak Analysis: - Epidemiologist John Snow identifies cholera outbreak source in London using spatial analysis. - Maps casualties' residences and nearby water sources to pinpoint the outbreak's origin. 3. Early 20th Century - Photozincography and Layered Mapping: - Photozincography development allows maps to be split into layers for vegetation, water, etc. - Introduction of layers, later a key feature in GIS, for separate printing plates. 4. Mid-20th Century - Computer Facilitation of Cartography: - Waldo Tobler's 1959 publication details using computers for cartography. - Computer hardware development, driven by nuclear weapon research, leads to broader mapping applications by early 1960s. 5. 1960 - Canada Geograph...

Platforms in Remote Sensing

In remote sensing, a platform is the physical structure or vehicle that carries a sensor (camera, scanner, radar, etc.) to observe and collect information about the Earth's surface. Platforms are classified mainly by their altitude and mobility : Ground-Based Platforms Definition : Sensors mounted on the Earth's surface or very close to it. Examples : Tripods, towers, ground vehicles, handheld instruments. Applications : Calibration and validation of satellite data Detailed local studies (e.g., soil properties, vegetation health, air quality) Strength : High spatial detail but limited coverage. Airborne Platforms Definition : Sensors carried by aircraft, balloons, or drones (UAVs). Altitude : A few hundred meters to ~20 km. Examples : Airplanes with multispectral scanners UAVs with high-resolution cameras or LiDAR High-altitude balloons (stratospheric platforms) Applications : Local-to-regional mapping ...

Spectral Signature vs. Spectral Reflectance Curve

Spectral Signature A spectral signature is the unique pattern in which an object: absorbs energy reflects energy emits energy across different wavelengths of the electromagnetic spectrum. ✔ Key Points Every natural and man-made object on Earth interacts with sunlight differently. These interactions produce a distinct pattern , just like a "fingerprint". Sensors on satellites record these patterns as digital numbers (DN values) . These patterns help to identify and differentiate objects such as vegetation, soil, water, snow, buildings, minerals, etc. ✔ Examples of Spectral Signatures Healthy vegetation → High reflectance in NIR , strong absorption in red Water → Strong absorption in NIR and SWIR , low reflectance Dry soil → Gradual increase in reflectance from visible to NIR Snow → High reflectance in visible , low in SWIR ✔ Why Spectral Signature Matters It allows: Land cover classification Chan...

Model GIS object attribute entity

These concepts explain different ways of organizing, storing, and representing geographic information in a Geographic Information System (GIS) . They include database design models (ER model), data structure models (Object and Attribute models), and spatio-temporal representations that integrate location, entities, and time . Together, they help GIS manage both spatial data (where things are) and descriptive information (what they are and how they change over time) . 1. Object-Based Model (Object-Oriented Data Model) The Object-Based Model treats geographic features as independent objects that combine spatial geometry and descriptive attributes within a single structure. Core Concept: Each geographic feature (such as a building, road, or river ) is represented as a self-contained object that stores both: Geometry – location and shape (point, line, polygon) Attributes – descriptive properties (name, type, length, capacity) Unlike older georelational models , which stored spatial ...

GIS data continuous discrete ordinal interval ratio

In Geographic Information Systems (GIS) , data is categorized based on its nature (discrete or continuous) and its measurement scale (nominal, ordinal, interval, or ratio). These distinctions influence how the data is collected, analyzed, and visualized. Let's break down these categories with concepts, terminologies, and examples: 1. Discrete Data Discrete data is obtained by counting distinct items or entities. Values are finite and cannot be infinitely subdivided. Characteristics : Represent distinct objects or occurrences. Commonly represented as vector data (points, lines, polygons). Values within a range are whole numbers or categories. Examples : Number of People : Counting individuals on a train or in a hospital. Building Types : Categorizing buildings as residential, commercial, or industrial. Tree Count : Number of trees in a specific area. 2. Continuous Data Continuous data is obtained by measuring phenomena that can take any value within a range...
