Climate Change Adaptation

Climate change adaptation refers to the actions taken to prepare for and respond to the impacts of climate change. It involves adjusting human and natural systems to minimize vulnerability and maximize resilience in the face of changing climate conditions. Here are some key aspects of climate change adaptation:
Risk Assessment and Vulnerability Analysis: Assessing the risks and vulnerabilities associated with climate change is an important first step. This involves understanding the potential impacts on various sectors, such as agriculture, water resources, infrastructure, and human health. Identifying vulnerable populations and areas helps prioritize adaptation efforts.
Adaptation Planning: Developing adaptation plans at various scales, from national to local, is essential. These plans outline strategies, policies, and measures to address specific climate change risks and vulnerabilities. Stakeholder engagement and participation are critical for developing inclusive and effective adaptation plans.
Water Management: Climate change affects water availability and quality, making water management a key aspect of adaptation. This includes improving water storage, efficiency, and conservation measures, developing drought and flood management strategies, and promoting integrated water resource management.

The Problem: Climate Change
Extreme Heat
What we know India is already experiencing a warming climate. What could happen Unusual and unprecedented spells of hot weather are expected to occur far more frequently and cover much larger areas. Under 4°C warming, the west coast and southern India are projected to shift to new, high-temperature climatic regimes with significant impacts on agriculture. What can be done With built-up urban areas rapidly becoming “heat-islands”, urban planners will need to adopt measures to counteract this effect.
Changing Rainfall Patterns
What we know A decline in monsoon rainfall since the 1950s has already been observed. The frequency of heavy rainfall events has also increased. What could happen A 2°C rise in the world’s average temperatures will make India’s summer monsoon highly unpredictable. At 4°C warming, an extremely wet monsoon that currently has a chance of occurring only once in 100 years is projected to occur every 10 years by the end of the century. An abrupt change in the monsoon could precipitate a major crisis, triggering more frequent droughts as well as greater flooding in large parts of India. India’s northwest coast to the south eastern coastal region could see higher than average rainfall.
Dry years are expected to be drier and wet years wetter. What can be done Improvements in hydro-meteorological systems for weather forecasting and the installation of flood warning systems can help people move out of harm’s way before a weather-related disaster strikes. Building codes will need to be enforced to ensure that homes and infrastructure are not at risk. Droughts
What we know Evidence indicates that parts of South Asia have become drier since the 1970s with an increase in the number of droughts. Droughts have major consequences. In 1987 and 2002-2003, droughts affected more than half of India’s crop area and led to a huge fall in crop production. What could happen Droughts are expected to be more frequent in some areas, especially in north-western India, Jharkhand, Orissa and Chhattisgarh.
 Crop yields are expected to fall significantly because of extreme heat by the 2040s. What can be done Investments in R&D for the development of drought-resistant crops can help reduce some of the negative impacts.
Groundwater
What we know More than 60% of India’s agriculture is rain-fed, making the country highly dependent on groundwater. Even without climate change, 15% of India’s groundwater resources are overexploited. What could happen Although it is difficult to predict future ground water levels, falling water tables  can be expected to reduce further on account of increasing demand for water from a growing population, more affluent life styles, as well as from the services sector and industry. What can be done The efficient use of ground water resources will need to be incentivized.
Glacier Melt
What we know Glaciers in the northwestern Himalayas and in the Karakoram range - where westerly winter winds are the major source of moisture - have remained stable or even advanced. On the other hand, most Himalayan glaciers - where a substantial part of the moisture is supplied by the summer monsoon - have been retreating over the past century. What could happen At 2.5°C warming, melting glaciers and the loss of snow cover over the Himalayas are expected to threaten the stability and reliability of northern India’s primarily glacier-fed rivers, particularly the Indus and the Brahmaputra.  The Ganges will be less dependent on melt water due to high annual rainfall downstream during the monsoon season. The Indus and Brahmaputra are expected to see increased flows in spring when the snows melt, with flows reducing subsequently in late spring and summer. Alterations in the flows of the Indus, Ganges, and Brahmaputra rivers could significantly impact irrigation, affecting the amount of food that can be produced in their basins as well as the livelihoods of millions of people (209 million in the Indus basin, 478 million in the Ganges basin, and 62 million in the Brahmaputra basin in the year 2005). What can be done Major investments in water storage capacity would be needed to benefit from increased river flows in spring and compensate for lower flows later on.
Sea level rise
What we know Mumbai has the world’s largest population exposed to coastal flooding, with large parts of the city built on reclaimed land, below the high-tide mark.  Rapid and unplanned urbanization further increases the risks of sea water intrusion. What could happen With India close to the equator, the sub-continent would see much higher rises in sea levels than higher latitudes. Sea-level rise and storm surges would lead to saltwater intrusion in the coastal areas, impacting agriculture, degrading groundwater quality, contaminating drinking water, and possibly causing a rise in diarrhea cases and cholera outbreaks, as the cholera bacterium survives longer in saline water. Kolkata and Mumbai, both densely populated cities, are particularly vulnerable to the impacts of sea-level rise, tropical cyclones, and riverine flooding. What can be done Building codes will need to be strictly enforced and urban planning will need to prepare for climate-related disasters. Coastal embankments will need to be built where necessary and Coastal Regulation Zone codes enforced strictly.
Agriculture and food security
What we know Even without climate change, world food prices are expected to increase due to growing populations and rising incomes, as well as a greater demand for biofuels.  Rice: While overall rice yields have increased, rising temperatures with lower rainfall at the end of the growing season have caused a significant loss in India’s rice production. Without climate change, average rice yields could have been almost 6% higher (75 million tons in absolute terms).  Wheat: Recent studies shows that wheat yields peaked in India and Bangladesh around 2001 and have not increased since despite increasing fertilizer applications. Observations show that extremely high temperatures in northern India - above 34°C - have had a substantial negative effect on wheat yields, and rising temperatures can only aggravate the situation. What could happen Seasonal water scarcity, rising temperatures, and intrusion of sea water would threaten crop yields, jeopardizing the country’s food security. Should current trends persist, substantial yield reductions in both rice and wheat can be expected in the near and medium term. Under 2°C warming by the 2050s, the country may need to import more than twice the amount of food-grain than would be required without climate change. What can be done Crop diversification, more efficient water use, and improved soil management practices, together with the development of drought-resistant crops can help reduce some of the negative impacts. Energy Security
What we know Climate-related impacts on water resources can undermine the two dominant forms of power generation in India - hydropower and thermal power generation - both of which depend on adequate water supplies to function effectively. To function at full efficiency, thermal power plants need a constant supply of fresh cool water to maintain their cooling systems. What could happen The increasing variability and long-term decreases in river flows can pose a major challenge to hydropower plants and increase the risk of physical damage from landslides, flash floods, glacial lake outbursts, and other climate-related natural disasters. Decreases in the availability of water and increases in temperature will pose major risk factors to thermal power generation. What can be done Projects will need to be planed taking into account climatic risks.
Water Security
What we know Many parts of India are already experiencing water stress. Even without climate change, satisfying future demand for water will be a major challenge. Urbanization, population growth, economic development, and increasing demand for water from agriculture and industry are likely to aggravate the situation further. What could happen An increase in variability of monsoon rainfall is expected to increase water shortages in some areas. Studies have found that the threat to water security is very high over central India, along the mountain ranges of the Western Ghats, and in India’s northeastern states. What can be done Improvements in irrigation systems, water harvesting techniques, and more-efficient agricultural water management can offset some of these risks.
Health
What we know Climate change is expected to have major health impacts in India- increasing malnutrition and related health disorders such as child stunting - with the poor likely to be affected most severely. Child stunting is projected to increase by 35% by 2050 compared to a scenario without climate change. Malaria and other vector-borne diseases, along with and diarrheal infections which are a major cause of child mortality, are likely to spread into areas where colder temperatures had previously limited transmission. Heat waves are likely to result in a very substantial rise in mortality and death, and injuries from extreme weather events are likely to increase. What could happen Health systems will need to be strengthened in identified hotspots. What can be done Improvements in hydro-meteorological systems for weather forecasting and the installation of flood warning systems can help people move out of harm’s way before a weather-related disaster strikes. Building codes will need to be enforced to ensure that homes and infrastructure are not at risk.
Migration and conflict
What we know South Asia is a hotspot for the migration of people from disaster-affected or degraded areas to other national and international regions.  The Indus and the Ganges-Brahmaputra-Meghna Basins are major trans boundary rivers, and increasing demand for water is already leading to tensions among countries over water sharing. What could happen Climate change impacts on agriculture and livelihoods can increase the number of climate refugees. What can be done Regional cooperation on water issues will be needed.
Climate Action: Everyone can help limit climate change. From the way we travel, to the electricity we use and the food we eat, we can make a difference. Start with these 10 actions to help tackle the climate crisis. Save energy at home
Much of our electricity and heat are powered by coal, oil, and gas. Use less energy by lowering your heating and cooling, switching to LED light bulbs and energy-efficient electric appliances, washing your laundry with cold water, or hanging things to dry instead of using a dryer. Learn more about saving energy at home at UN.org Walk, cycle, or take public transport
The world’s roads are clogged with vehicles, most of them burning diesel or petrol. Walking or riding a bike instead of driving will reduce greenhouse gas emissions – and help your health and fitness. For longer distances, consider taking a train or bus. And carpool whenever possible. Learn more about walking, cycling, or taking public transport at UN.org Eat more vegetables
Eating more vegetables, fruits, whole grains, legumes, nuts and seeds, and less meat and dairy, can significantly lower your environmental impact. Producing plant-based foods generally results in fewer greenhouse gas emissions and requires less energy, land, and water. Learn more about eating more vegetables at UN.org Consider your travel
Aeroplanes burn large amounts of fossil fuels, producing significant greenhouse gas emissions. That makes taking fewer flights one of the fastest ways to reduce your environmental impact. When you can, meet virtually, take a train, or skip that long-distance trip altogether. Learn more about considering your travel at UN.org Throw away less food
When you throw food away, you're also wasting the resources and energy that were used to grow, produce, package, and transport it. And when food rots in a landfill, it produces methane, a powerful greenhouse gas. So use what you buy and compost any leftovers. Learn more about throwing away less food at UN.org Reduce, reuse, repair & recycle
Electronics, clothes, and other items we buy cause carbon emissions at each point in production, from the extraction of raw materials to manufacturing and transporting goods to market. To protect our climate, buy fewer things, shop second-hand, repair what you can, and recycle. Learn more about reducing, reusing, repairing & recycling at UN.org Change your home's source of energy
Ask your utility company if your home energy comes from oil, coal, or gas. If possible, see if you can switch to renewable sources such as wind or solar. Or install solar panels on your roof to generate energy for your home. Learn more about changing your home's source of energy at UN.org Switch to an electric vehicle
If you plan to buy a car, consider going electric, with more and cheaper models coming on the market. Even if they still run on electricity produced from fossil fuels, electric cars help reduce air pollution and cause significantly fewer greenhouse gas emissions than petrol or diesel-powered vehicles.
What is your climate footprint?
A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Globally, the average carbon footprint is closer to 4 tons.
What is the average climate footprint?
Meanwhile, the global average energy-related carbon footprint is around 4.7 tonnes of CO2 per person – the equivalent of taking two round-trip flights between Singapore and New York, or of driving an average SUV for 18 months.
