A little about climate

A little about climate

Environmental think tank Council on Energy, Environment, and Water have carried a first-of-its-kind district-level climate vulnerability assessment, or Climate Vulnerability Index (CVI), in which it has analyzed 640 districts in India to assess their vulnerability to extreme weather events such as cyclones, floods, heatwaves, droughts, etc.

HOW IS THE CLIMATE VULNERABILITY INDEX ASSESSED?

The CVI maps exposure (that is whether the district is prone to extreme weather events), sensitivity (the likelihood of an impact on the district by the weather event), and adaptive capacity (what the response or coping mechanism of the district is). It helps map critical vulnerabilities and plan strategies to enhance resilience and adapt by climate-proofing communities, economies, and infrastructure. Instead of looking at climate extremes in isolation, the study looks at the combined risk of hydro-met disasters, which are floods, cyclones, and droughts, and their impact. The study does not take into consideration other natural disasters such as earthquakes.

WHY DOES INDIA NEED A CLIMATE VULNERABILITY INDEX?

According to Germanwatch’s 2020 findings, India is the seventh-most vulnerable country with respect to climate extremes. Extreme weather events have been increasing in the country such as supercyclone Amphan in the Bay of Bengal, which is now the strongest cyclone to be recorded in the country. Recent events such as the landslides and floods in Uttarakhand and Kerala have also increased in the past decade. Another CEEW study has found that three out of four districts in India are extreme event hotspots, with 40 percent of the districts exhibiting a swapping trend, that is traditionally flood-prone areas are witnessing more frequent and intense droughts and vice-versa. Further, the IPCC states that every degree rise in temperature will lead to a three percent increase in precipitation, causing an increased intensification of cyclones and floods.

WHAT ARE THE FINDINGS OF THE CLIMATE VULNERABILITY INDEX?

According to CVI, Assam, Andhra Pradesh, Maharashtra, Karnataka, and Bihar are most vulnerable to extreme climate events such as floods, droughts, and cyclones in India.

 While 27 Indian states and union territories are vulnerable to extreme climate events, 463 districts out of 640 are vulnerable to extreme weatDhemaji and Nagaon in Assam, Khammam in Telangana, Gajapati in Odisha, Vizianagaram in Andhra Pradesh, Sangli in Maharashtra, and Chennai in Tamil Nadu are among India’s most climate-vulnerable districts. More than 80 percent of Indians live in districts vulnerable to climate risks. 17 out of 20 people in India are vulnerable to climate risks, out of which every five Indians live in areas that are extremely vulnerable.

More than 45 percent of these districts have undergone “unsustainable landscape and infrastructure changes’’. 183 hotspot districts are highly vulnerable to more than one extreme climate event. 60% of Indian districts have medium to low adaptive capacity in handling extreme weather events these districts don’t have robust plans in place to mitigate the impact.
 North-eastern states are more vulnerable to floods, South and central are most vulnerable to extreme droughts, whereas
 59 and 41 percent of the total districts in the eastern and western states, respectively, are highly vulnerable to extreme cyclones.

WHICH ARE THE BEST PERFORMING STATES AND WHY?

The CVI has ranked 20 states out of which Assam and Andhra Pradesh are the most vulnerable to extreme weather events, and Kerala, Tripura, and West Bengal are the least vulnerable. The study points out that the difference in the vulnerability of states ranked is marginal, making all states vulnerable. But Kerala and West Bengal have performed well comparatively, despite both being coastal states and dealing with the threat of cyclones and floods annually. The reason why these states have performed better is that they have stepped up their climate action plans as well as preparedness to handle an extreme weather event. The Index takes into account certain indicators when assessing the preparedness of a state or district. These include the availability of critical infrastructures like cyclone and flood shelters, government mechanisms in place including updating of disaster management plans, mitigation strategies, standard operating procedures before, during, and after an extreme weather event such as how people and livestock are being evacuated or how food is being mobilized and how the administration prevents loss of lives and livelihoods.

WHAT HAS COMPOUNDED THE IMPACT OF WEATHER EVENTS ?

Apart from the intensity and frequency of extreme weather events which have increased in the country, the report finds that “land disruptions’’ have increased the impact of these events. Land disruptions primarily point to anthropogenic activity including change of land use, increased construction, reclaiming of land for development resulting in the disappearance of forests, wetlands, mangroves, and other such habitats. These ecosystems have traditionally acted as natural buffers against such extreme weather, reducing the impact. With their disappearance, the impact of the weather events has increased and is being felt more across the country.

WHAT ARE THE RECOMMENDATIONS THAT HAVE BEEN MADE?

Develop a high-resolution Climate Risk Atlas (CRA) to map critical vulnerabilities at the district level and better identify, assess, and project chronic and acute risks such as extreme climate events, heat and water stress, crop loss, vector-borne diseases, and biodiversity collapse. A CRA can also support coastal monitoring and forecasting, which are indispensable given the rapid intensification of cyclones and other extreme events.

Establish a centralized climate-risk commission to coordinate the environmental de-risking mission.
Undertake climate-sensitivity-led landscape restoration focused on rehabilitating, restoring, and reintegrating natural ecosystems as part of the developmental process.

Integrate climate risk profiling with infrastructure planning to increase adaptive capacity. Provide for climate risk-interlinked adaptation financing by creating innovative CVI-based financing instruments that integrate climate risks for an effective risk transfer mechanism.
