ജൂൺ ജൂലൈ തിമിർത്തു പെയ്തു ഓഗസ്റ്റ് സെപ്റ്റംബർ ശക്തി കുറയുന്ന പഴയ കാലവർഷ മഴയുടെ സ്വഭാവം മാറുകയാണോ..??

സെപ്റ്റംബർ മാസത്തിൽ ശരാശരി മഴ 260 mm. സെപ്റ്റംബർ 12ഓടെ തന്നെ ഇത്തവണ 280 mm മറികടന്നു. 2019 ലും സെപ്റ്റംബർ 12ഓടെ 260 mm മറികടന്നു.

കഴിഞ്ഞ വർഷം സെപ്റ്റംബർ മാസത്തിൽ ആകെ പെയ്തത് 426 mm, 64% അധികം.

കാലവര്ഷം ഔദ്യോഗികമായി അവസാനിക്കാൻ 18 ദിവസം ബാക്കി നിൽക്കേ 5 ജില്ലകൾ സീസണിൽ മൊത്തത്തിൽ ലഭിക്കേണ്ട മഴ മറികടന്നു. കോഴിക്കോട്, കണ്ണൂർ, കോട്ടയം, തിരുവനന്തപുരം, കാസറഗോഡ് ജില്ലകളാണ് . മൺസൂൺ ശരാശരി മറികടന്നത്.

ജൂൺ 1 മുതൽ സെപ്റ്റംബർ 30 വരെ നീളുന്ന കാലവർഷത്തിൽ കോഴിക്കോട് ജില്ലയിൽ ലഭിക്കേണ്ട ശരാശരി മഴ 2577 mm ആണ്. ഇത്തവണ സെപ്റ്റംബർ 12 ആയപ്പോൾ തന്നെ അത്‌ 2973 mm ആയി.

അതെ പോലെ തന്നെ കാസർഗോഡ്, കണ്ണൂർ, കോട്ടയം,തിരുവനന്തപുരം ജില്ലകളും മറികടന്നു.

2019ൽ സെപ്റ്റംബർ 12 ആയപ്പോൾ 8 ജില്ലകൾ ശരാശരി മഴയെ മറികടന്നിരുന്നു. കഴിഞ്ഞ വർഷം കോഴിക്കോട്, പാലക്കാട്‌, കണ്ണൂർ, കാസറഗോഡ്, തൃശൂർ, കോട്ടയം എറണാകുളം, മലപ്പുറം, എന്നീ ജില്ലകളാണ് ശരാശരി മഴ സെപ്റ്റംബർ ആദ്യം തന്നെ മറികടന്നത്.

2018, 2019, 2020 വർഷത്തിൽ ഓഗസ്റ്റ് മാസത്തിലും മഴ യിൽ ശരാശരിയെക്കാൾ വൻ വർദ്ധനവ് കാണിച്ചിരുന്നു.

സെപ്റ്റംബർ ൽ 2018 വളരെ കുറവ് മഴ ലഭിച്ചപ്പോൾ 2019 ൽ വൻ വർദ്ധനവ്. 2020 കൂടി...

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...
