The conclusion provides a summary of the most important results from the study and underlines the need to take action to address the consequences of droughts, floods, and fires on water resources.
Introduction
Water is fundamental to life and an indispensable resource for human well-being, agriculture, and industrial activity. However, with fires, droughts, and floods happening in different parts of the globe, there are new pressures on water supplies and availability. Any natural or man-made structure that stores or supplies water is considered a water resource. There are several sorts of water resources, such as surface water, groundwater, and rainwater. Surface water refers to water located on the earth’s surface, including lakes, rivers, and streams. Groundwater is the term for the water that is stored in underground aquifers. Rainwater, on the other hand, is water that has been harvested from natural precipitation sources like rain. Water shortage is a problem in certain parts of the world, while other areas have abundant water. Natural disasters like droughts, floods, and fires have contributed to this difference. In certain regions, access to clean water is quite complex, yet in others, freshwater is easily accessible. Droughts are extended periods of below-average rains and low water levels, which result in water shortages and poor water quality (Khalid et al., 2020). Floods are unexpected and catastrophic phenomena that cause rivers to overflow and inundate low-lying regions, significantly damaging water infrastructure, including reservoirs, treatment plants, and distribution systems (Liu et al., 2019). Fires are catastrophic incidents that have far-reaching effects on environmental factors, including water quality. Millions of people throughout the globe are affected by the combination of these occurrences, which has a significant influence on water supplies and their availability.
History of the Topic
The effect of drought, floods, and wildfires on water supplies has been a subject of concern for decades. In the past, these occurrences were seen more as natural catastrophes requiring management and response rather than as potential long-term threats to water resources. However, in recent decades, as the effects of climate change have been more apparent, more focus has been placed on how these extreme weather events affect water supplies (Tzanakakis, Paranychianakis, & Angelakis, 2020). The frequency and intensity of extreme precipitation events are rising as a result of climate change, which may have severe consequences for water resources (Khalid et al., 2020). Thus, there has been increasing debate and worry about the need to understand better and manage the effects of floods, fires, and drought on water resources. This has led to increased investment in research and development of water management measures, such as the production of drought-resistant crops, the building of flood protection infrastructure, and the creation of fire early warning systems (Tzanakakis, Paranychianakis, & Angelakis, 2020).
Moreover, there has been increased cooperation between water management organizations, governments, and communities to create integrated ways to manage water resources in response to these issues. This involves promoting water conservation and using alternate water sources, as well as developing water resource management plans that account for the effects of drought, fires, and floods (Khalid et al., 2020). In general, there has been a growing recognition of the challenges posed by natural disasters like drought, floods, and fires and a growing commitment to addressing these challenges and ensuring the sustainable management of water resources, as evidenced by the long history of discussions on the topic.
Significance of the Study
The investigation of water sources and drought, fires, and floods is crucial for several reasons. First, climate change is increasing the intensity and frequency of drought, fires, and floods, all of which may have severe consequences for water resources. Understanding the difficulties governments and communities experience as a consequence of climate change necessitates an investigation of these effects. Second, governments and NGOs can mitigate these events’ toll on water resources by improving their preparedness and response to them, based on findings on this topic (Tzanakakis, Paranychianakis, & Angelakis, 2020). Third, water sources are essential to sustaining diverse ecosystems and populations of plants and animals. Understanding how natural disasters like drought, fire, and flood affect water bodies might help us better safeguard these vital resources (Nielsen‐Gammon et al., 2020). Four, this study has the potential to impact public health significantly. Researching how natural disasters like droughts, fires, and floods affect water resources may reveal hidden health hazards and guide preventative actions (Khalid et al., 2020). Lastly, the study may provide a permanent economic benefit. Notably, water is a vital commodity in many economic spheres, including agriculture, power generation, and industrial production. Perhaps, the financial costs of natural disasters like drought, fires, and floods may be better understood, and preventative actions can be better planned if researchers examine the effects of these calamities on water resources.
Statistical Evidence
In this section, the current research paper provides some statistics regarding the impacts of drought, wildfires, and floods on water resources. In 2021, more than 45 percent of the continental United States was experiencing drought, and more than 15 percent was in a catastrophic drought, as the United States Drought Monitor reported. Some estimates put the annual impact of drought on American water sources and agriculture at more than $10 billion. Droughts may cause considerable drops in water levels in lakes and reservoirs, as shown in the case of Nevada’s Lake Mead, where the water level dropped by more than 140 feet (43 meters) during the period between 2000 and 2014 (Nielsen‐Gammon et al., 2020). In the early 2000s, Australia had a severe drought in the Murray-Darling Basin, which led to a 40% loss in surface water resources and had far-reaching consequences for the country’s agricultural sector, industrial base, and municipal water systems. Dam levels dropped, water restrictions were tightened, and agricultural yields were cut due to the Millennium Drought, which stretched from 1997 to 2009, according to the Australian Bureau of Meteorology.
In addition, there has been a rise in the frequency of catastrophic wildfires in the United States, with an annual average of nearly 7 million acres burnt since 2010. Over 4 million acres were burnt in California alone during the 2020 wildfire season, making it one of the worst on record for the United States. According to research published in the journal “Water Resources Research,” the area burnt by wildfires in the western United States rose by more than 400% between 1984 and 2015, causing an increase in runoff, erosion, and sedimentation in water bodies, particularly rivers, and streams. Wildfires have also been shown to destroy water infrastructure such as reservoirs, treatment facilities, and pipelines, resulting in high repair and rebuilding expenditures.
Floods are the most prevalent natural catastrophe in the United States, costing an annual average of $8 billion in losses (Liu et al., 2019). Extreme soil erosion, familiar after floods in places like the American Midwest, may have a negative effect on water quality and the landscape’s capacity to retain and restore water resources (Khalid et al., 2020). Further, during the monsoon season, approximately 40 percent of Bangladesh is submerged in water, forcing millions of people to relocate and causing widespread destruction and pollution of the country’s water supply. These statistics show how devastating drought, wildfires, and floods can be to water resources and how crucial it is to have a solid strategy and management in place to lessen the impact.
Discussion
Impact of ongoing regional fires on water resources.
Wildfires in the United States have increased in frequency since the mid-1980s. This is most pronounced in the western U.S., and increases have been observed for both forest and grassland wildfires. Much of the increase in wildfire frequency and area burned has been correlated with drier conditions, earlier snowmelt (especially at mid-elevations), and severe droughts associated with climate change. More significant fire activity is not limited to the U.S., with increases observed in regions and ecosystem types across the globe (Williams et al., 2022). Increases in fire frequency have profound implications for human health and environmental quality. These effects have been relatively well studied for air quality, yet fires pose potential risks to water resources (Williams et al., 2022). Wildfires alter stream flow response to precipitation and mobilize a variety of pollutants through downwind deposition or subsequent runoff. These pollutants include sediment, dissolved organic compounds, and metals threatening water sources (Vargas & Paneque, 2019). Nutrients released following fires can contribute to downstream eutrophication and harmful algal blooms, adversely affecting drinking water quality and recreational uses, such as boating and swimming (Vargas & Paneque, 2019; Williams et al., 2022). The same fire-mobilized pollutants impacting water quality can also be harmful to aquatic life, at least in the short term. Wildfires can also alter hydrology (Yang, Yang, & Xia, 2021). Wildfires can change the flow patterns of streams and rivers, reducing the amount of water available for use. The increased runoff and erosion from burn areas can result in increased flash flooding and debris flows, which can cause damage to infrastructure and threaten public safety. Overall, the impacts of wildfires on water resources can be long-lasting and can affect the availability and quality of water for both human and ecological needs.
Impact of the ongoing drought on water resources
Water resources are vital to public health and the economy. Water resources contribute considerably to the resilience of many other sectors, including agriculture, energy, and manufacturing. Persistent drought has resulted in effects on water resources, including loss of water supply, poor water quality from sources that may need further treatment to satisfy drinking water and other usage requirements, difficulty in accessing alternative and supplemental water sources due to high demand and competition for limited sources, and higher costs associated with reacting to drought impacts on water sources (Nielsen‐Gammon et al., 2020). During drought years, several regions increase their dependence on groundwater. According to some estimates, groundwater contributes more than forty percent of the water utilized for agricultural and household water supplies in the United States (Bhaga et al., 2020). Pumping at higher rates during droughts may diminish the future availability of such sources, although initiatives to restore subsurface aquifers can aid in the fight against the impacts of drought.
A prolonged lack of rain and an increase in the loss of water via evaporation have depleted surface water supplies. Drought-related rises in river, lake, and reservoir temperatures cause more water to evaporate, reducing water availability and worsening water quality as contaminants become more concentrated (Bhaga et al., 2020). Additionally, groundwater resources are not replenished at a regular pace because of decreased precipitation and higher evaporation of surface water. Drought causes a decrease in precipitation, which in turn decreases the water supply and forces people to rely excessively on what little water is left. Furthermore, silt, ash, charcoal, and woody debris may be carried to surface waterways by runoff from drought-related wildfires, lowering water quality. Due to increasing demand and competition for limited supplies, the ongoing drought has also led to an inability to obtain alternate and supplemental water sources.
The ongoing drought has also increased costs related to responding to drought impacts on water sources. Since the cost to each nation varies widely depending on the steps they take, it is impossible to calculate the total amount spent to mitigate the effects of the prolonged drought on water supplies. However, several nations are investing heavily in programs to enhance water management, conservation, and supply through technical solutions, including desalination, water recycling, and reuse systems. For instance, billions of dollars have been set aside in the United States for drought mitigation and water conservation initiatives (Bhaga et al., 2020). Australia’s federal government has spent millions on drought-related programs, including emergency water infrastructure projects and studies to manage better and save water, which totals $1.3 billion (Nielsen‐Gammon et al., 2020). Countries with dry climates and water shortages, such as those in the Middle East, have had to spend heavily on desalinization systems.
Impact of ongoing floods on water resources
Ongoing flooding may have a devastating effect on water supplies, with both immediate and far-reaching repercussions for ecosystems and human communities. In the short run, floods may contaminate water sources by sweeping trash and other contaminants into rivers and lakes. This poses a significant risk to public health since it may facilitate the proliferation of bacteria and other disease-causing germs. Chemicals and other harmful compounds may be carried by floodwaters, endangering aquatic life and tainting drinking water sources (Liu et al., 2019). In the long run, floods can cause lasting damage to water infrastructure, such as water treatment plants, reservoirs, and distribution systems. This may lead to widespread water shortages and make it more challenging to provide people with clean, safe water. River and stream flows may be disrupted by floods, leading to sedimentation, erosion, and even chemical changes in the water (Liu et al., 2019). This threatens aquatic ecosystems, endangers species, and depletes safe water supplies for human use and agriculture.
Ongoing flooding’s effect on water supplies also creates an enormous financial burden on nations. Because it varies widely by nation, area, and condition, it is difficult to quantify how much money countries spend to manage the effect of recurring floods on water resources. However, many countries are investing significant amounts of money in this area, given that the impacts of floods on water resources also manifest in public health, the environment, and the economy. In the United States, for instance, the federal government puts much money into levees, dams, and other flood-proof infrastructure to lessen the damage from floods (Liu et al., 2019). The European Union (E.U.) does the same thing in Europe by providing financing to its member states for disaster risk reduction and management, which includes flood preparation and response. In addition to government support, private enterprises, and non-governmental groups are investing much money in methods to mitigate the effect of flooding on water resources. In order to encourage more responsible water usage, several businesses have begun to adopt water management best practices, invest in water-saving technology, and form partnerships with nearby residents. The long-term cost of ignoring floods’ effect on water resources might be significantly greater if proper action is not taken now.
Mitigation of the Impacts of Ongoing Regional Drought, Fires, and Floods on Water Resources
Long-term regional drought, fires, and floods may have a significant and enduring effect on available water resources. Mitigating these impacts requires a multi-faceted approach that includes both short-term and long-term solutions such as water conservation and management, wildfire management, flood management, watershed management, and climate change adaptation. In times of drought, it is essential to encourage water conservation via education and outreach initiatives and to develop water-saving technology and practices (Paul et al., 2022; Teague et al., 2021). In addition, the wise use of both surface and groundwater resources is an integral part of good water management that may ensure enough supplies at all times. This might need the creation of brand-new water storage and distribution networks or the extension of existing ones. Implementing fire management techniques, such as controlled burns and fire breaks, may lower the danger of wildfires and save water supplies (Paul et al., 2022).
In addition, floodplain mapping, early warning systems, and the building of flood barriers and levees are all examples of efficient flood control methods that may lessen the toll floods have on water supplies (Teague et al., 2021). There is substantial evidence that maintaining wetland and riparian areas, among other land-use strategies, may help lessen the likelihood and impact of floods. Effective watershed management, which includes conserving and restoring watersheds, may lessen the effects of drought, fire, and flooding on water supplies (Vargas & Paneque, 2019). This may entail implementing the best management techniques, such as minimizing soil erosion and sedimentation and enhancing water quality (Teague et al., 2021). Last but not least, reducing the greenhouse gas emissions that cause climate change and preparing for the repercussions of a changing climate, such as more frequent and extreme droughts, fires, and floods, are essential for reducing the adverse effects of these events on water supplies (Paul et al., 2022). Countries may already be taking these steps to protect their water supplies, which remain essential to human survival despite frequent and severe droughts, fires, and floods.
Conclusion
The effects of ongoing regional droughts, fires, and floods on water resources are profound and likely to endure for a long time. Wildfires modify the stream flow response to precipitation and mobilize a range of contaminants through downstream deposition or subsequent runoff. The silt, dissolved organic compounds, and metals that make up these contaminants pose a hazard to the world’s water resources. Nutrients that are released as a result of fires may lead to eutrophication and toxic algal blooms farther downstream. This has a negative impact on the quality of drinking water as well as recreational activities such as boating and swimming. Persistent regional droughts have resulted in consequences on water resources, including loss of water supply, poor water quality from sources that may need further treatment to fulfill drinking water and other consumption requirements, difficulties accessing alternative and supplementary water sources owing to high demand and competition for restricted sources, and increased costs associated with responding to drought impacts on water sources. On the other side, persistent floods may damage water sources because they wash garbage and other impurities into rivers and lakes. This may make the water unfit for human consumption. In addition, floods may carry with them pollutants and other potentially hazardous materials, which may imperil aquatic life and contaminate sources of drinking water. Floods have the potential to inflict long-term damage to water infrastructure, including water treatment facilities, reservoirs, and distribution networks. In order to lessen the severity of these effects, a multidimensional strategy is required. This strategy must incorporate both immediate and long-term responses to the problem, including water conservation and management, management of wildfires and floods, management of watersheds, and adaptation to climate change. However, more sophisticated measures and global partnerships are required to hasten to mitigate these adverse events on water sources. Droughts, fires, and floods continue to be critical for human existence, and these natural disasters continue to have a negative impact on water resources. It is important to note that many countries around the world are already adopting these measures to reduce and mitigate the impacts of these natural disasters.
