New Delhi: Sustainable funding systems are required, it said. Effects are no longer restricted to far-off environmental forecasts: they are shaping how people perform their jobs, obtain necessary resources, commute to work, rear food and reside in cities.
Climate risks specifically identified for India range from the country’s very large population, this huge coastline, negative effects of ecological range shifts and dependence on monsoon rainfall as well as exposure to many Himalayan hazards.
Heat is becoming a daily threat
The growing intensity and frequency of heatwaves are putting pressure on public health, workplaces, electricity systems and water supplies. In recent climate reporting, an uptick in heat and humidity could threaten parts of Asia more grimly with dangerous conditions if emissions are allowed to rise unabated.
Outdoor workers, construction labourers, farmers and street vendors — delivery personnel as well as people living in poorly ventilated houses are vulnerable to the effects of extreme heat. It can also impair productivity, cause dehydration and aggravation of heart, lung and pre-existing kidney conditions.
Urban areas are at greater risk as concrete surfaces, traffic and low vegetation create heat-island effects. Delhi, Ahmedabad, Mumbai and Hyderabad could have hotter nights which limits the body’s ability to recuperate after daytime heat.
Erratic monsoons affect food and income
Indian agriculture is still strongly dependent on the timing and trends of monsoon rains. Climate change is predicted to alter rainfall patterns — making some areas susceptible to heavy rain and others more periods of unrelenting dry weather.
Without doubt, heavy rain can decay crops, hasten dispersed damages broken soil and drown famous grounds or fields while inadequate amount of rainfall can decay yields and become expensive right later on because it erased some water from beneath and increased the price of irrigation. Asia is already warned of potential food supply disruption and price surge due to floods, droughts and heat stress, from the climate assessments at the UN level.
The effects extend beyond farmers. Food prices, rural employment; transport, storage and household budgets can all be affected by changes in the profile of crop output.
Flooding and urban drainage
Indian cities have been seeing rising intense rainfall events and this overwhelms drainage system. Rainfall that goes beyond the ability of urban infrastructure to cope easily causes flooding within hours, particularly in roads, homes, railways/aerodromes/commercial places.
As urbanisation continues and more wetlands are drained for construction, climate change comes into play. Communities living in informal settlements tend to be poorer without secure housing, sanitation and emergency services; hence they are often exposed to the highest risks.
Contamination of the drinking water, as well as a growing number of infectious diseases (after the funds are allocated to flood rescue efforts) add further threats.
Water scarcity grows alongside floods
AbstractOne of the hardest climate challenges for India is that the same area at one end could have excess water due to heavy rainfall, while during dry period it can be under-supplied or even running out on water. On top of this, shifts in rainfall patterns exacerbated by climate change, groundwater depletion and increasing demand and decreasing recharge may place pressure on household and agricultural water supplies.
Climate projections viewed in reports linked to the UN have said a large part of the inhabitants’s populace could be threatened with water pressure by 2050.
Water shortages can affect:
- Drinking-water access.
- Crop irrigation.
- Industrial production.
- Hydroelectric power.
- Household sanitation.
- Livestock and rural livelihoods.
- Food prices.
Cities may need stronger rainwater harvesting, groundwater regulation, leakage control, wastewater reuse and watershed protection.
Himalayan glaciers under pressure
Warming and reduction of snow & Ice in Hindu Kush Himalaya. In the very short term, glacial retreat can lead to a rise in flooding and of glacial-lake outburst events while over the long-term it diminishes assured water security for those rivers that rely on snow and glacier melt.
Himalayan glaciers could decline significantly in high-emissions pathways, according to the UN’s most recent climate assessment.
In India, Himalayan cryosphere changes may have implications for Ganges, Brahmaputra & Indus river systems. Shifting timing of seasonal water availability, landslides, flash floods and threats hydropower and agriculture may especially impact communities further downstream.
Rising risks along the coast
The coastlines of India remain vulnerable to long-term impacts of sea-level rise, coastal erosion, storm surges associated with extreme weather events like cyclones and consequent saltwater intrusion. Housing, roads, ports and wetlands freshwater source is likely to be threatened in low-lying cities and densely populated coastal settlements.
Urban centres along the coastal line, such as Mumbai, Chennai, Kolkata, Kochi, Surat and Visakhapatnam stand to become increasingly exposed to flooding under a changing climate as sea levels rise and extreme weather events become more common.
This is one of the reasons saltwater intrusion is so damaging to agricultural lands and our aquifers. Communities that rely on fishing may also suffer from warmer seas, shifting marine ecosystems and more hazardous conditions out at sea.
Health impacts are expanding
Climate change affects health directly through heat stress and indirectly through changes in disease patterns, water quality, nutrition and air pollution.
Potential health impacts include:
- Heat exhaustion and heatstroke.
- Cardiovascular and respiratory complications.
- Waterborne diseases after floods.
- Vector-borne diseases.
- Malnutrition after crop losses.
- Mental-health stress following disasters.
- Pregnancy and infant-health risks.
- Reduced access to healthcare during extreme events.
Climate-sensitive diseases such as dengue, malaria and diarrhoeal illnesses may become more difficult to control when temperature, rainfall and humidity create favourable conditions for mosquitoes or contaminate water supplies.
Unequal effects on vulnerable communities
Not all Indians are affected by climate change equally. Disadvantaged population: People from low-income households, informal workers, small farmers and fisher communities, older persons and children and people with disabilities usually have lower capacities to prepare for or recover from disasters.
While heat exposure, flood risk and poor drainage hound residents of informal settlements their access to cooling, insurance, savings or alternative housing is limited. The IPCC has warned that urban populations that are socially and economically marginalised will be among the first to suffer from the hazards of climate change.
And climate adaptation needs to be about inequality, not only big infrastructure.
Impact on work and productivity
Outdoor workers are among the most impacted by increasing temperatures. It is possible that Farmers, Construction Workers, Sanitation Staff, Traffic police and Street Vendors would be compelled to work fewer hours in the hot zones.
When conditions become unsafe heat can reduce physical performance, increase accidents and lead to loss of income for workers. Higher cooling costs, reduced productivity and disruptions from floods or power cuts are also issues for businesses.
Early warnings, shaded rest areas, drinking water and adjusted working hours that are part of heat-action plans can mitigate some risk.
Energy demand under pressure
When it is hotter for a longer time more fans, coolers and air conditioners are needed. That can put pressure on electricity grids, as power use peaks during heatwaves.
Transmission lines, substations and generation facilities can also suffer from extreme weather damage. Changing rainfall and glacier conditions may impact hydropower output, while thermal power plants rely on a steady water supply.
Future demand will require expanded renewables, more resilient grids, greater efficiency and affordable cooling, he added.
India’s adaptation priorities
The UN climate assessments emphasise that adaptation and emissions reduction must proceed together. India needs to reduce climate risks already locked into the system while also limiting future warming through cleaner energy, efficient transport, sustainable buildings and ecosystem protection.
Important adaptation measures include:
- Heat-action plans in cities and districts.
- Climate-resilient drainage systems.
- Better flood forecasting and early warnings.
- Drought-resistant crops.
- Efficient irrigation.
- Protection of wetlands and mangroves.
- Stronger coastal zoning.
- Safer housing in vulnerable locations.
- Climate-resilient hospitals and schools.
- Improved disaster-response systems.
Local planning is essential because climate risks differ between the Himalayas, Indo-Gangetic plains, drylands, coasts and urban regions.
Need for climate-resilient cities
The role urban planning will play in how Indian cities deal with climate change Every city requires more trees, shaded streets, permeable surfaces and reinstituted lakes; proper drainage and heat-adaptive design.
Flooding and extreme heat would have to be mitigated in public transport systems. Hospitals, schools and emergency services needed backup power, water supplies and disaster-continuity plans.
Climate risk assessments should be integrated into infrastructure decisions, including roads, housing, industrial projects and new urban development.
Everyday changes already visible
These are some of the daily routines that climate change is altering. Individuals might change the hours they work on hot days, store additional water and spend more to cool down themselves or their homes, evade roads inundated by rainwater drainage systems, pick various harvests or relocate until further notification after a calamity.
Climate shocks will also raise food prices, electricity bills and insurance costs, as well as household health expenses. This is why climate change is as much an economic and social issue as it is an environmental one.
A warning for immediate action
UN climate assessments state emphatically that India is vulnerable to the confluence of risks associated with heat, water and food insecurity, health threats, infrastructure degradation and livelihood shocks.
Adaptations that avert risk for the most vulnerable will be critical; but without emission reductions, a climate-resilient future is not possible. Damage can be limited by stronger early-warning systems, climate-sensitive urban planning, resilient agriculture and water conservation as well as accessible healthcare.
Climate change, thus, is no longer a distant threat for India. Because it is being influenced more and more by regular choices regarding where they live, how they work, what they eat, as well as travel decisions and whether basic services stay afloat throughout severe weather.
