Rainfall Forecast and Weather Warnings based on 0830 hours IST of today:

♦ An off-shore trough at mean sea level runs from north Maharashtra coast to north Kerala coast. The east-west shear zone runs roughly along 15°N across the peninsular India in mid tropospheric levels and likely to persist during next 3-4 days. Under their influence:

i) Fairly widespread to widespread rainfall with isolated heavy falls, thunderstorm & lightning very likely over Peninsular India during

next 5 days.

ii) Heavy to very heavy rainfall at isolated places very likely over Coastal Andhra Pradesh & Yanam, Konkan & Goa and Coastal

Karnataka on 12th September, 2020.

♦ The monsoon trough lies to the north of its normal position. The monsoon trough very likely to shift further southward due to formation of a low pressure area over Westcentral Bay of Bengal off Andhra Pradesh coast around 13th September. Under their influence:

i) Fairly widespread rainfall with isolated thunderstorm & lightning very likely over Northeast and adjoining East India. Heavy rainfall at

isolated places also very likely over Sub-Himalayan West Bengal & Sikkim and northeast India (mainly Assam & Meghalaya) during next 3-4 days.

♦ Rainfall distribution and intensity very likely to increase over Odisha, Coastal Andhra Pradesh & Yanam, Telangana, Maharashtra and Gujarat State from 12th September onwards. Isolated heavy falls also very likely over these regions during next 3-4 days.

♦ Moderate thunderstorm with lightning very likely at isolated places over East Uttar Pradesh, South Rajasthan, Gujarat state, Bihar, Madhya Pradesh, Chhattisgarh, Jharkhand, Vidarbha, Sub-Himalayan West Bengal & Sikkim, Assam & Meghalaya, Telangana, Coastal Andhra Pradesh & Yanam, Coastal Karnataka, Kerala, Rayalseema and Konkan & Goa during next 12 hours

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 ...

Overview of Disasters in India

India's Vulnerability to Natural Disasters India's diverse geography and climate make it highly susceptible to a range of natural disasters. These events, including earthquakes, tsunamis, floods, droughts, cyclones, and landslides, can have devastating consequences for millions of people and the economy. Major Natural Disasters Affecting India: Earthquakes: Tectonic Setting: India's position on the Indian Plate, which is colliding with the Eurasian Plate, makes it prone to seismic activity. Impact: Earthquakes can cause widespread destruction, including building collapses, landslides, and tsunamis. The 2001 Gujarat earthquake is a prime example of such devastation. Tsunamis: Oceanic Triggers: Underwater earthquakes and volcanic eruptions can generate tsunamis, as seen in the 2004 Indian Ocean Tsunami. Impact: Coastal areas are particularly vulnerable to tsunamis, which can lead to massive loss of life and property. Floods: Monsoon Influence: India's...

Water Act 1974

The Water (Prevention and Control of Pollution) Act of 1974 is a significant piece of legislation in India aimed at preventing and controlling water pollution. Here are some key facts about the Act: 1. Objective: The primary objective is to prevent and control water pollution and maintain or restore the wholesomeness of water in the country. 2. Establishment of Boards: - Central Pollution Control Board (CPCB): The Act mandates the establishment of the CPCB to oversee and coordinate activities across the nation and advise the Central Government. - State Pollution Control Boards (SPCBs): Each state is required to establish its own SPCB to plan comprehensive programs for the prevention and control of pollution. 3. Powers and Functions: - The Boards have the authority to inspect any sewage or trade effluents, works, and plants for the treatment of sewage and trade effluents. - They can establish standards for the discharge of pollutants into water bodies and ensure adherence to...

Environment Management DRR

Environmental management plays a crucial role in disaster risk reduction (DRR) by harnessing the power of natural ecosystems to prevent and mitigate the impacts of disasters. By protecting and restoring these ecosystems, we can strengthen community resilience and promote sustainable development. Interconnections Between Environmental Management and DRR: Ecosystem-Based Disaster Risk Reduction (Eco-DRR): Natural Barriers: Ecosystems like forests, wetlands, and coral reefs act as natural barriers, reducing the impact of hazards like floods, landslides, and storm surges. Resilience Building: Healthy ecosystems enhance community resilience by absorbing excess rainfall, preventing erosion, and mitigating the effects of climate change. Environmental Considerations in Disaster Planning: Sustainable Practices: Incorporating environmental considerations into disaster planning helps prevent further environmental degradation, which can exacerbate disaster impacts. Resource Conservati...

Forset management and water conservation

Forest management and water conservation are closely intertwined concepts, as forests play a crucial role in maintaining water resources. Here's an explanation of their connection: 1. Water Regulation: Forests act as natural sponges, absorbing rainwater and releasing it gradually. Trees help regulate water flow, preventing rapid runoff and reducing the risk of floods. 2. Groundwater Recharge: Trees contribute to groundwater recharge by allowing rainwater to percolate into the soil. This replenishes underground aquifers, which are important sources of freshwater. 3. Erosion Control: Forests provide vegetation cover that protects soil from erosion caused by rainfall. This, in turn, helps maintain the quality of water bodies by preventing sedimentation. 4. Streamflow Maintenance: Healthy forests ensure consistent streamflow. Trees release water through transpiration, influencing local and regional precipitation patterns and sustaining rivers and streams. 5. Biodiversity and Water Qual...
