    What’s the news?

    • Disruptive weather events, including El Niño and changing precipitation patterns, are impacting India’s agriculture, resulting in reduced crop yields, water stress, and rising food prices.

    Central idea

    • India has experienced a series of disruptive weather and climate phenomena in recent times, highlighting the complexity of our precipitation system. This complexity poses significant challenges to the sustainability and resilience of development projects in the mountains and floodplains.

    How do western disturbances influence India’s climate?

    • Origin: Western disturbances are weather systems that originate in the Mediterranean region and travel eastward towards South Asia, including India.
    • Winter and Spring Impact: During the winter and spring seasons, these disturbances bring much-needed moisture to the western Himalayan region and parts of northern India. This moisture contributes to rainfall and snowfall in these areas, which are essential for agriculture, water resources, and ecosystems.
    • Unusual Behavior: The Western disturbance typically follows a seasonal pattern, but in some years, it can exhibit unusual behavior. For example, it may persist late into the summer months, affecting weather patterns beyond its usual timeframe.
    • Impact on Southwest Monsoon: When a Western disturbance lingers into the summer, it can influence the southwest monsoon, which is crucial for India’s agriculture. The interaction between these weather systems can lead to unpredictable and sometimes extreme weather events, including heavy rainfall, landslides, and flooding.
    • Concerns: The unusual behavior of the Western disturbance can raise concerns about the sustainability and resilience of development projects in regions affected by these weather events, such as the western Himalayan region and northern India.

    El Niño’s Influence on Monsoons

    • El Niño:
      • El Niño is a climate phenomenon characterized by the warming of sea surface temperatures in the eastern and central tropical Pacific Oceans.
      • This warming disrupts normal atmospheric circulation patterns, leading to significant climatic impacts worldwide.
    • Impact on the Southwest Monsoon:
      • El Niño events can influence the Indian Southwest Monsoon, which is responsible for the majority of India’s annual rainfall.
      • While not all El Niño events have adverse effects on the monsoon, their intensification can lead to drier conditions in some parts of India.
      • El Niño tends to weaken the monsoon, reducing the amount and distribution of rainfall.
    • Interaction with Indian Ocean Dipole (IOD):
      • The relationship between El Niño and the monsoon has evolved over time.
      • In some cases, when El Niño affects the monsoon, another climate phenomenon in the Indian Ocean, known as the positive-phase IOD, can balance the consequences.
      • The IOD can influence monsoon variability and rainfall patterns, either mitigating or exacerbating the impact of El Niño.
    • Predictive Value of Models:
      • Dynamic regression models have suggested that a significant portion of the inter-annual variability of the Southwest Monsoon can be attributed to the combined effects of El Niño and the IOD.
      • This indicates the predictive value of these models in understanding and forecasting monsoon behavior during El Niño events.
    • Food Security Implications:
      • El Niño’s influence on the monsoon has direct implications for food security in India.
      • Reduced monsoon rainfall can delay the onset of rains, affect crop sowing, and result in hot temperatures that negatively impact crop growth and soil moisture.
      • Crop yields, especially for water-intensive crops like rice and soybean, can be significantly affected during El Niño years, leading to food production challenges.

    Climate

    How are agriculture and water dependency intricately linked in India?

    • Two Types of Water for Agriculture:
      • Agriculture in India relies on two primary sources of water: green water and blue water.
      • Green water refers to rain-fed soil moisture that is utilized by crops and eventually transpires into the atmosphere.
      • Blue water includes the water found in rivers, lakes, reservoirs, and groundwater, which is essential for irrigation as well as drinking and industrial use.
    • Importance of Green Water:
      • Despite significant investments in dams, reservoirs, and irrigation systems, approximately half of the cultivated area in India depends on green water.
      • Green water is crucial for rainfed agriculture, as it provides moisture for crops and contributes to the overall water availability for agriculture.
    • Water Requirements for the Daily Diet:
      • The daily diet of individuals in India, from cooking oil to diverse foods, is associated with a substantial water footprint.
      • On average, an individual’s daily diet in India requires approximately 3,268 liters of water per day, subject to regional variability.
      • A significant portion (about 75%) of this water footprint is attributed to green water, highlighting the importance of rainfed agriculture to food and nutritional security.
    • Dependency on Green Water in Irrigated Areas:
      • Even in areas with access to irrigation, many dominant crops still depend on green water to varying degrees.
      • For example, during the kharif season, rice paddy under irrigation uses green water for about 35% of its water requirements.
      • Staple crops like tur dal, soybean, groundnut, and maize also rely considerably on green water, particularly during specific growing seasons.
    • Impact of Climate Phenomena on Green Water:
      • Climate phenomena like El Niño can disrupt the availability of green water by delaying the start of rains and affecting sowing schedules.
      • Higher temperatures during El Niño events may negatively influence plant growth and soil moisture, impacting crop yields.
    • Food Production Challenges:
      • During El Niño years, when green water availability may be compromised, crop production can be significantly affected.
      • For instance, there was a 28% decline in soybean production in India during the 2015–2016 El Niño year compared to the average

      • Central India experiences significant and persistent water stress.
      • Water stress is driven primarily by the demand for irrigation, particularly during the rabi season, which relies on blue water sources such as rivers and reservoirs.
    • Extent of Water Stress:
      • Approximately 70–78% of the landscape in Central India experiences water stress for four or more months each year.
      • Among the 17 urban centers in the region, 11 face water stress for six to eight months, with Nagpur enduring water stress for the longest duration.
      • Changing precipitation patterns, including declining monsoon precipitation since the 1950s, have exacerbated water stress in Central India.

    Adaptation Strategies

    • Diversifying Agro-Food Systems:
      • To adapt to changing precipitation patterns and water availability, there’s an emphasis on diversifying agro-food systems.
      • This includes shifting away from water-intensive crops to alternative, less water-dependent crops like millets.
    • Reducing Dependence on Water-Intensive Crops:
      • A key adaptation strategy is reducing dependence on water-intensive crops, particularly during periods of water stress.
      • Crop diversification may involve promoting the cultivation of millets and alternative varieties of dominant cereals.
    • Shorter growing cycles:
      • Advisories to farmers may include shifting to crops with shorter growing cycles.
      • Shorter growing cycles can help adapt to changing precipitation patterns and mitigate the risks associated with extended dry periods.

As UN Secretary-General António Guterres wisely noted, Extreme weather events will happen. But they do not need to become deadly disasters. Together, through decisive action and unwavering commitment, we can forge a more resilient and sustainable world for generations to come.

     

  • What is heat index and why is it important to measure?

    What’s the news?

    • In August, the coastal regions of Iran bore witness to an astonishing and potentially life-threatening event: a scorching heat index of 70 degrees Celsius (°C). Public holidays were declared on August 2 and 3 due to what was described as unprecedented heat.

    Central idea

    • The alarming incidents of rising heat temperatures are not isolated; Iran had already grappled with extreme heat earlier in the year when the Persian Gulf Airport recorded a heat index of 66.7°C. The dire consequences of such soaring temperatures demand our attention and action.

    What is the heat index?

    • The heat index, also known as the apparent temperature or feels-like temperature, is a measure of how hot it feels to the human body when relative humidity is factored in along with the actual air temperature.
    • In essence, it quantifies the discomfort or perceived warmth caused by the combination of high temperatures and high humidity.

    How is the heat index calculated?

    • Dr. Robert Steadman’s Formula: Dr. Robert Steadman, a professor at Colorado State University, developed a complex formula in 1979 to calculate the heat index. This formula considers various parameters, including air temperature and relative humidity.
    • Parameters in the Formula: The formula takes into account the following parameters:
      • Air temperature (in degrees Fahrenheit).
      • Relative humidity (expressed as a decimal, e.g., 50% RH becomes 0.50).
      • Coefficients specific to the formula (c1, c2, c3, c4, c5, c6, c7, c8, and c9).
    • Nonlinear Relationship: The formula is complex because it accounts for the nonlinear relationship between temperature, humidity, and how humans perceive heat.
    • Global Variations: Different countries may have their own variations of heat index calculations, but Dr. Steadman’s formula is widely recognized and used as a standard reference.

    Significance of measuring the heat index

    • Accurate Perception of Heat: The heat index provides a more accurate representation of how hot it feels to the human body compared to the actual air temperature. It factors in relative humidity, which significantly affects human comfort in hot conditions.
    • Health Impact Assessment: Measuring the heat index is crucial for assessing the potential health risks associated with hot weather. It helps identify conditions that may lead to heat-related illnesses, including heat exhaustion and heatstroke.
    • Preventing Heat Stress: High humidity levels, considered in the heat index, can lead to heat stress. Monitoring the heat index assists in recognizing situations where heat stress is more likely to occur, prompting individuals to take the necessary precautions.
    • Issuing Public Warnings: Weather agencies and authorities use the heat index to issue heat advisories and warnings to the public. These warnings inform people about the heightened risks associated with high heat index values, encouraging them to take protective measures.

    • With its known ability to suppress rainfall and disrupt agricultural cycles, El Nino’s effects are already being felt.

    Understanding El Nino and La Nina

    • El Nino and La Nina are two opposite phases of the El Nino-Southern Oscillation (ENSO) cycle.
    • ENSO is a naturally occurring phenomenon that involves the interaction between the ocean and atmosphere in the equatorial Pacific.

    Here is a detailed comparison of El Nino and La Nina

    El Nino La Nina
    Definition Warmer-than-normal sea surface temperatures Cooler-than-normal sea surface temperatures
    Frequency Every two to seven years Every two to seven years
    Duration Several months to a year or more Several months to a year or more
    Impact on winds Weakens trade winds, leading to changes in patterns Strengthens trade winds, leading to changes in patterns
    Impact on rains Reduces rainfall and can cause droughts Increases rainfall and can cause flooding
    Impact on temp. Warmer-than-average temperatures Colder-than-average temperatures
    Global effects Droughts in Asia and Africa, floods in Americas Floods in Asia and Africa, droughts in South America

    Impact on India

    El Nino La Nina
    Associated with weak monsoons and drought-like conditions in India Associated with above-normal rainfall and floods in India
    Sea surface temperature in the equatorial Pacific Ocean rises above normal levels Sea surface temperature in the equatorial Pacific Ocean drops below normal levels
    Changes in the atmospheric circulation patterns Changes in the atmospheric circulation patterns
    Shift in the location of the jet stream, affecting the strength and direction of the monsoon winds Increase in the strength of the monsoon winds, bringing more moisture and rainfall to India
    Results in reduced rainfall, dry spells, and heatwaves, leading to crop failures and water scarcity Excessive rainfall can also lead to floods and landslides, causing damage to crops and infrastructure

    Broader Implications:

    [A] Agriculture

    • Rainfall Deficit: August’s nationwide rainfall stands at 30.7% below normal, erasing the initial 4.2% surplus from the southwest monsoon.
