Rising Evaporative Demand Spotlights India’s Data and Research Gap
India is witnessing a significant increase in evaporative demand driven by rising temperatures and changing climate patterns. Evaporative demand—the amount of water lost to the atmosphere—directly affects agriculture, water supply, and ecosystem health.
Despite its critical importance, India lacks comprehensive data and research on this phenomenon. The absence of detailed evaporation measurements and analysis hampers effective water management policies and climate adaptation strategies.
To address water scarcity and support sustainable agriculture, India must invest in advanced monitoring systems and expand research on evaporative demand. Bridging this gap will help policymakers make informed decisions to mitigate climate impacts and ensure water security for millions.
FAQ Section
What is evaporative demand?
Evaporative demand refers to the potential water loss from soil and plants into the atmosphere, influenced by temperature, humidity, wind, and solar radiation.
Why is evaporative demand rising in India?
Rising temperatures and climate change are increasing the rate at which water evaporates from land and crops.
How does this affect India?
Increased evaporative demand can worsen water scarcity, reduce crop yields, and stress ecosystems.
What data is lacking in India?
There is insufficient real-time monitoring and research on evaporation rates across different regions.
How can India improve?
By developing robust data collection systems, enhancing research, and integrating findings into water management policies.
