landslides
A landslide is the movement of rock, soil, and debris down a slope due to gravity. Landslides can be triggered by factors like heavy rainfall, earthquakes, volcanic activity, or human activities.
landslides
The Economic Survey of India (2021-22) reported that natural disasters, including landslides, have led to substantial economic losses, with the cost of recovery often exceeding billions of dollars.

disaster management
Disaster management refers to the systematic process of planning, organizing, coordinating, and implementing measures to prevent, mitigate, respond to, and recover from disasters
disaster
India is one of the most disaster-prone countries in the world. According to the National Disaster Management Authority (NDMA), over 70% of India’s landmass is prone to earthquakes, and over 60% is prone to cyclones.
Government Initiatives:
1.National Disaster Management Authority (NDMA):
Established in 2005, NDMA is the apex body responsible for formulating policies, plans, and guidelines for disaster management.
2.Disaster Management Act (2005):
This act provides the legal framework for disaster management and outlines the roles and responsibilities of various stakeholders.
3.National Disaster Response Force (NDRF):
Created in 2006, NDRF is a specialized force trained for disaster response and recovery.
4.State Disaster Management Authorities (SDMAs):
Each state has its own disaster management authority to coordinate responses at the regional level.
5.National Policy on Disaster Management (2009):
This policy aims to provide a framework for disaster risk reduction and emphasizes a proactive approach.
6.Early Warning Systems:
The Indian Meteorological Department (IMD) and other agencies have developed early warning systems for cyclones, floods, and earthquakes.
7.Disaster Management Training:
Various training programs and simulations are conducted for officials, emergency responders, and the public to enhance preparedness and response capabilities.
The Sendai Framework for Disaster Risk Reduction 2015-2030 is a global initiative adopted during the Third World Conference on Disaster Risk Reduction in Sendai, Japan, in March 2015.
Understanding Disaster Risk:
Strengthening Disaster Risk Governance:
Investing in Disaster Risk Reduction:
Enhancing Disaster Preparedness for Response:
Building Back Better:
sendai Goals:
1.Reduction in Disaster Mortality: Aim to reduce global disaster mortality by 2030.
2.Reduction in Affected Population: Reduce the number of people affected by disasters.
3.Reduction in Economic Losses: Decrease the economic losses caused by disasters, focusing on infrastructure and livelihoods.
4.Increase in Resilience: Enhance resilience through the integration of disaster risk reduction into national and local policies

According to the National Centre for Coastal Research (NCCR) under the Ministry of Earth Sciences, approximately 33% of India’s coastline has been experiencing varying degrees of erosion.

Area Coverage: wetland
India has about 7.58 million hectares of wetlands, covering nearly 4.7% of the country’s geographical area. These include inland wetlands like lakes and ponds, as well as coastal wetlands such as mangroves and mudflats.

Biodiversity:
Wetlands in India support approximately 20% of the country’s biodiversity. They are home to numerous species of birds, fish, amphibians, and plants, many of which are endemic or endangered.

Mechanisms for Compliance:
Emissions Trading: Allowed countries that had excess emission allowances (i.e., they emitted less than their permitted level) to sell this excess capacity to countries that were over their targets.
Clean Development Mechanism (CDM): Permitted Annex I countries to invest in emission-reduction projects in developing countries, thereby earning saleable certified emission reduction (CER) credits.
Joint Implementation (JI): Allowed Annex I countries to earn emission reduction units (ERUs) from projects in other Annex I countries.
