How is climate change linked to algal blooms?
Climate change, according to scientists, will have a wide range of repercussions on freshwater and marine habitats. These impacts, together with nutrient pollution, may cause toxic algal blooms to occur more frequently, in more waterbodies, and with greater intensity. Algal blooms pose a threat to human health, the environment, and the economy.
Climate Change Impacts on Algal Blooms
1: Temperature increase in the water
Harmful algae typically bloom during the hot summer months or when water temperatures are higher than normal. Warmer water as a result of climate change may benefit toxic algae in a variety of ways:
• Warmer water is preferred by toxic blue-green algae because it prevents water from mixing, causing algae to grow thicker and quicker.
• Warmer water encourages tiny creatures to move more easily through it and helps algae to float to the surface more quickly.
• Algal blooms absorb sunlight, warming the water and encouraging new blooms.
2: Salinity variations
Droughts may become more often as a result of climate change, making freshwater saltier. This can result in saltwater algae invading freshwater habitats.
3: Increased carbon dioxide levels
To live, algae require carbon dioxide. Increased carbon dioxide levels in the air and water can promote the fast development of algae, particularly harmful blue-green algae that can float to the top of the water.
4: Changes in precipitation
Extreme weather followed by periods of drought can result in additional algal blooms. Climate change may alter rainfall patterns, resulting in periods of drought and violent storms.This can result in greater nutrient runoff into bodies of water, fuelling more algal blooms.
5: Rising sea levels
Scientists anticipate that sea levels will increase by up to one meter by 2100. This would result in shallower and more stable coastal water, ideal conditions for algae development.
What are the possible solutions?
A variety of measures have been shown to be successful in combating algae overgrowth. Grass strips used as buffer zones around agricultural fields may naturally filter minerals from runoff.
Netsol's newer decentralized wastewater treatment units may be installed on a small or medium scale to treat sources in rural agricultural zones, small villages, or industrial areas.Aerators can help avoid algae blooms in lakes, lagoons, and ponds.
In response to dangerous algal blooms, regulators are increasingly tackling nutrient contamination throughout watersheds. Netsol's wastewater treatment expertise can assist you in negotiating the new regulatory landscape. It's never been simpler to introduce our membrane aerated biofilm reactor (MABR) technology's extraordinarily high nutrient removal rates and the Indian-made quality of our aerators to your town, resort, agricultural zone, or industrial location.
Netsol Water is a large water and wastewater treatment company in India that manufactures WTPs, WWTPs, STPs, and ETPs, among other services. It has become our job to rescue the earth.The firm manufactures equipment’s and is dedicated to offering practical solutions that enable businesses to thrive.
