Effects Of Climate Change On Water Resources – Although the effects of climate change are predicted to vary widely and everywhere, the loss of water deserves serious consideration, as the well-being of communities – and countries – hangs in the balance.

Today, long-term climate change is seen as the biggest global problem of the 21st century. According to NASA research, the last five years have been considered the hottest in the history of visuals

Effects Of Climate Change On Water Resources

. Among the inevitable consequences of climate change, the most important is its impact on water resources – the foundation of environmental sustainability, economic growth, and global security.

Understanding Climate Change Impacts On Water Resources

The most important effect of climate change on the world’s water resources is the disruption of the water cycle. Therefore, an increase in temperature will increase the amount of water vapor in the atmosphere, a change in the pattern and intensity of precipitation, an increase in evaporation from the earth’s surface, a decrease in snow cover and melting glaciers. The effects of climate change on water resources affect all major sectors of the economy.

The expansion of hydrothermal vents due to climate change causes sea level rise and saltwater intrusion into freshwater, reducing the quantity and quality of their reserves. The movement of salt water over the mouths of the rivers destroys fishing activities, adversely affects water intake activities, disrupts agriculture, and causes salinization of the soil. Small islands are particularly vulnerable to sea level rise: It causes events such as flooding, erosion, and other hazards in the coastal zone, threatening infrastructure and homes.

The melting of glaciers and snow cover due to the increase in temperature causes the water to decrease, so the water decreases during the warm and dry periods in the regions supplied with melt water from the bars. mountains. In the past decade, the size of the Himalayan glaciers has decreased by two-thirds, while the glaciers of the Andes have almost disappeared.

. The thawing of glaciers increases landslides, thus posing a threat to structures in glacial regions.

Impact Of Climate Change On Hydrology And Water Resources

Changes in precipitation patterns due to weather conditions can affect soil moisture. Low recharge and increased evaporation in the long absence of rainfall can lead to chronic droughts that threaten water and food security. By the middle of the century, rising temperatures and decreasing soil moisture in the Eastern Amazon are expected to gradually replace the rainforest, which plays an important role in water management, and the savanna.

According to projections, climate change by 2050 will increase river flow and water availability in high latitudes and humid tropical regions. In mid-arid and semi-arid regions, however, these indicators decrease, and the amount of available water resources decreases.

According to research, the amount of water in the largest lakes of the Niger, Senegal, and Lake Chad has decreased by 40 to 60 percent.

, and by 2020 nearly 250 million Africans will experience water scarcity due to climate change. Rainfall will decrease, temperatures will rise, agricultural areas and crop growing seasons will be shortened, and water systems and reservoirs will be damaged. Therefore, in some African countries, the yield from rain-fed crops could be reduced by 50 percent by 2020.

. The decrease in water availability will have a negative impact on the production capacity of the hydropower industry: by 2030, hydropower capacity in Eastern and Southern Africa will decrease by 20 percent

Drought and water scarcity in the upper latitudes, exacerbated by climate change, are creating competition for natural resources and forcing local residents to leave the region. It is estimated that an increase in temperature of 1 degree celsius in a country with an agricultural economy is associated with an increase in migration of up to 5 percent.

, the countries of the Horn of Africa – Somalia, Ethiopia, Eritrea, Kenya, Sudan, and South Sudan – are particularly vulnerable due to prolonged periods of drought.

Heavy rainfall in the middle and high latitudes will increase the costs of upgrading existing and building new flood protection areas and strengthening road and sewer infrastructure. However, for regions with moderate conditions, the increase in rainfall and the length of the growing season will have a positive effect on crop yields, which has been observed in the UK, Scandinavia, Europe, and North America.

How Modernizing Infrastructure Can Help To Capture More Storm Flow

Thus, climate change will affect spatial and temporal differences in water availability, creating new and worsening current water security problems in all regions of the world. Without effective water management, water scarcity due to climate change could cost some regions up to 6 percent of GDP.

. Depleting water resources can be a major challenge even for water-rich countries as they depend on imports of water-intensive products. Therefore, the water supply of other regions has a significant impact on the supply of agricultural products to the European Union: Up to 38 percent of the water used to grow imported agricultural products arrives in the EU from exporting countries.

The negative effects of climate change and recession related to GDP growth can be eliminated by properly distributing water resources, providing incentives to improve their performance, and attracting money to build water infrastructure.

Climate change adaptation includes risk mitigation measures and measures to increase the climate resilience of regions. Risk mitigation measures include preventing the negative impacts of climate change on the water sector. Some of these include reducing urban development in floodplains, developing and implementing water saving technologies in agriculture and industry, restoring and protecting wetlands, and planting forests. Measures to increase sustainability include reducing the negative effects of climate change by increasing the resilience of selected areas: replacing crops with less moisture- love and salt, building dams and canals, and changing floodplains for agriculture.

Impact Of Climate Change On Water Resources By Komaragiri Srinivasa Raju

Building sustainable infrastructure is a matter of human and public investment. Additional investment required to adapt infrastructure to climate change is estimated at 5 to 20 percent of its cost

And two to three times higher than the current funding level. According to the World Bank, the cost of adapting water infrastructure to climate change in the period from 2010 to 2050 is estimated at $75 billion to $100 billion per year.

. In developing countries with limited water infrastructure and high climate risks, this amount rises to $280 billion to $500 billion

Since much of our daily life and planning is determined by water systems, it is important to understand how climate change affects (and will affect) drinking water supplies, sanitation , consumption and energy production. Climate Change and Water Are Closely Linked

The relationship between water, energy, agriculture and climate is as important as it is complex. Climate change will destabilize the climate on which the world is built and threaten the security of water, food and energy systems. Over time, the effects of global warming due to the production of man-made greenhouse gases (GHGs) have become more apparent. In 2017, major GHGs, such as carbon, methane and nitrous oxide reached record levels. The annual carbon dioxide concentration reached a global average of 405 parts per million, the highest on record, matched by 800,000-year ice core data.

The 20 warmest years on record have occurred since 1995. 2017, according to NOAA’s State of the Climate 2017 report, was the third warmest year since the mid-1800s, and the warmest year El Niño does not warm the world. water. As the Earth’s average temperature continues to rise, we can expect a significant impact on water resources and potential negative impacts on these resources.

One of the sharpest views on water and climate came from the launch of the CDP Water Disclosure Project in 2009, focused on global business, said the project’s CEO, and Paul Dickinson,

“Most of the effects of climate change will be felt through changes in water availability patterns, with shrinking glaciers and changing precipitation patterns increasing droughts and floods. . If climate change is sharks and water is teeth, there’s a reason for it
