  • As the world warms and cool

    Why in the News?

    The rising demand for cooling is leading to increased fossil fuel consumption for electricity generation, which in turn contributes to climate change and gradually elevates atmospheric temperatures.

    What are the primary impacts of climate change on human societies?

    • Heat-Related Health Risks: Increased temperatures and more frequent heatwaves lead to higher incidences of heat-related illnesses and deaths. For instance, global heatwaves already result in approximately 12,000 fatalities annually.
    • Threats to Food Security: Extreme temperatures and unstable weather patterns negatively impact agricultural productivity, affecting food quality and availability, and driving up prices.
    • Access to Essential Services: Over 1.1 billion people face immediate risks due to inadequate access to cooling, impacting health services (like vaccine storage), food preservation, and economic productivity.
    • Increased Mortality: By 2050, deaths from extreme heat are projected to surge, with the World Health Organization predicting up to 255,000 heat-related fatalities each year.

    How Can Societies Effectively Adapt to the Ongoing Changes in Climate?

    • Promoting Energy-Efficient Cooling: Improve the efficiency of cooling devices to reduce energy demand and mitigate climate impacts. This includes transitioning away from hydrofluorocarbons (HFCs) under international agreements like the Kigali amendment.
    • Nature-Based Solutions: Implement alternatives to mechanical cooling, such as planting shade trees and using smart building designs to naturally regulate temperatures.
    • Policy and Technological Innovations: Governments should enforce strict compliance with energy efficiency standards for cooling equipment and incentivize the development of sustainable cooling technologies.

    What Role Does International Cooperation Play in Addressing Climate Change?

    • Global Agreements: Initiatives like the Paris Agreement and the Kigali amendment to the Montreal Protocol emphasize the need for unified international action to reduce greenhouse gas emissions and promote sustainable development goals.
    • Shared Resources and Technology Transfer: International efforts, such as those led by Rwanda and the African Group, advocate for access to energy-efficient technologies, particularly for developing nations.
    • Enhancing Compliance and Monitoring: Countries are urged to strictly adhere to global agreements, such as phasing down HFCs, to achieve climate targets and protect vulnerable populations.

    Way Forward:

    • Accelerate the Transition to Energy-Efficient Cooling: Enhance international efforts to double the average energy efficiency of cooling devices and support the shift to climate-friendly refrigerants.
    • Integrate Cooling Solutions into Climate and Development Policies: Recognize cooling as a development issue and address its critical role in poverty alleviation and achieving the Sustainable Development Goals (SDGs).
  • Spotlighting the work of the Economics Nobel winners

    Why in the News?

    • This year’s Nobel Prize in Economics, officially known as the Sveriges Riksbank Prize in Economic Sciences, was awarded to Daron Acemoglu, Simon Johnson, and James Robinson (AJR).  
    • AJR have highlighted the importance of institutions in development, but critics argue that this approach tends to favour Western liberal models over other institutional frameworks.

    Why Do Some Nations Succeed While Others Fail?

    • Role of Institutions: The economic success or failure of nations can often be traced back to the nature of their institutions. 
      • Inclusive institutions encourage economic activity by providing secure property rights, legal frameworks, and political systems that incentivize growth. 
      • In contrast, extractive institutions concentrate wealth and power in the hands of a few, leading to economic stagnation and social inequality.
    • Historical Path Dependence: Countries that experienced inclusive economic institutions early in their development tend to be more prosperous, while those with a history of extractive institutions face significant barriers to growth. Historical events shape the trajectory of institutional development and influence current outcomes.

    What Is the Impact of Historical Institutions on Current Economic Outcomes?

    • Colonial Legacy: Institutions established during colonialism, especially extractive ones, have long-lasting impacts. Areas with landlord-based land tenure systems or direct colonial rule have struggled with lower agricultural productivity, fewer social services, and weaker infrastructure.
    • Natural Experiment Evidence: AJR’s research used historical data, such as differences in settler mortality, to show that regions colonized by Europeans with high mortality rates ended up with extractive institutions that still negatively affect growth today.
    • Long-Term Development Patterns: The effects of historical institutions persist, shaping economic development, social structures, and governance even after countries gain independence or transition to new political systems.

    Why do critics argue that this approach tends to favour Western liberal models over other institutional frameworks?

    • Historical Bias: Critics argue that AJR’s approach overlooks the diverse paths of development, favoring Western institutions while underestimating non-Western experiences and historical complexities.
    • Western Norms as Universal: The framework tends to present Western liberal institutions as ideal models, disregarding how other systems might effectively function in different cultural and socio-political contexts.

    Why Are Inclusive Institutions Not More Widely Adopted?

    • Conflict of Interests: Powerful groups with control over resources have incentives to maintain extractive institutions to protect their wealth and power, resisting changes that would lead to a fairer distribution of economic benefits.
    • Collective Action Challenges: Reforming extractive institutions requires solving collective action problems where diverse groups must agree on new rules that may threaten the established elite’s interests.
    • Path Dependency: Historical conditions can create institutional inertia, making it challenging to shift from extractive to inclusive frameworks due to deep-rooted social, political, and economic norms.

    Way forward: 

    • Strengthen Inclusive Institutions: Focus on legal and policy reforms that secure property rights, ensure fair governance, and promote transparent decision-making, encouraging broad-based economic participation and growth.
    • Empower Marginalized Groups: Implement policies that reduce power concentration by supporting grassroots movements, enhancing education access, and providing economic opportunities to disadvantaged communities to overcome historical inequalities.

  • ‘Yield’ can’t be the sole indicator for agriculture

    Why in the News?

    Government must embrace a new approach where the success of agriculture is defined by its capacity to nourish people, support livelihoods, and safeguard our planet for future generations.

    What are the limitations of using yield as the sole indicator of agricultural success?

    • Nutritional Quality Neglect as per ICAR (Indian Council for Agricultural Research): Focusing on yield has led to a decline in the nutritional profile of crops. High-yielding varieties often have lower micronutrient densities, as seen in reduced zinc and iron levels in rice and wheat.
    • Increased Input Costs: Higher yield does not always correlate with increased farmer income. The cost of achieving additional yield may be high, especially as the response to fertilizers has declined significantly since the 1970s.
    • Biodiversity Loss: The emphasis on a few high-yielding varieties leads to the loss of diverse, local crop varieties. For example, India has lost around 104,000 rice varieties since the Green Revolution.
    • Environmental Impact: Intensive farming to maximize yield can degrade soil health, reduce water availability, and harm the ecosystem, making agriculture less sustainable.
    • Reduced Resilience: The prioritization of yield over other factors makes crops less resilient to extreme weather events such as floods, droughts, and heatwaves.

    How do other indicators complement yield in assessing agricultural sustainability?

    • Nutritional Output Per Hectare: This indicator measures not just the quantity but the quality of the food produced, addressing nutritional security.
    • Soil Health Metrics: Including soil biological activity and soil organic carbon in evaluations helps ensure long-term soil fertility and productivity.
    • Water-Use Efficiency: Metrics like water-use efficiency track the amount of water required to produce crops, promoting conservation.
    • Farm Biodiversity: Assessing crop diversity at the farm and regional levels (Landscape Diversity Score) improves resilience to pests, diseases, and climate variability.
    • Economic Resilience Metrics: Indicators such as income diversification (through intercropping, livestock rearing, etc.) can help measure farmers’ economic stability.
    • Environmental Impact Measures: Tracking parameters like carbon footprint and ecosystem services evaluates the broader impact of agricultural practices.

    What practices can farmers adopt to improve sustainability beyond just increasing yield? (Way forward)

    • Intercropping: Growing multiple crops together (e.g., sugarcane with vegetables) can provide year-round income and enhance soil health.
    • Agroecological Approaches: Practices such as crop rotation, organic farming, and reduced pesticide use help maintain biodiversity and soil fertility.
    • Water Management Techniques: Using methods like drip irrigation and AI-powered tools for optimal irrigation ensures better water use.
    • Integrated Pest Management (IPM): Combining biological, mechanical, and chemical control methods reduces reliance on harmful pesticides.
    • Conservation Agriculture: Techniques such as no-till farming and mulching help improve soil structure and retain moisture.
    • Adopting Climate-Resilient Varieties: Growing drought-tolerant or flood-resistant crop varieties helps mitigate the impacts of climate change.

  • How did the Haber-Bosch process change the world?

    Why in the News?

    One hundred million tonnes of nitrogen are extracted from the atmosphere and transformed into fertilizer through the Haber-Bosch process, adding 165 million tonnes of reactive nitrogen to the soil.

    What is the Nitrogen molecule and how is it availed in Nature?

    • The nitrogen molecule (N2) consists of two nitrogen atoms joined by a triple bond, sharing three pairs of electrons. This triple bond makes the molecule extremely stable and nearly inert, requiring a significant amount of energy (946 kJ/mol) to break.
      • When the triple bond is broken, nitrogen atoms can form reactive nitrogen compounds like ammonia (NH3), ammonium (NH4+), or nitrates (NO3–). 
      • These compounds are essential for plant growth as they help synthesize enzymes, proteins, and amino acids.
    • Lightning generates enough energy to break the N2 triple bond, producing nitrogen oxides (NO and NO2) that can combine with water vapor to form nitric and nitrous acids. These acids add reactive nitrogen to the soil through rainfall.
    • Certain bacteria, such as Azotobacter and Rhizobia, fix atmospheric nitrogen through biological processes.
      • Rhizobia forms symbiotic relationships with legumes, while Azolla, an aquatic fern, also fixes nitrogen via its symbiotic cyanobacterium.

    The Haber-Bosch process synthesizes ammonia by reacting nitrogen (N2) with hydrogen (H2) under high pressure (200 atm) and moderate temperature (200°C), using a catalyst (typically iron oxides).

    What is the Haber-Bosch process?

    • The Haber-Bosch process synthesizes ammonia by reacting nitrogen (N2) with hydrogen (H2) under high pressure (200 atm) and moderate temperature (200°C), using a catalyst (typically iron oxides).
    • The process was developed by Fritz Haber, who found that high pressure and a suitable catalyst were key to converting nitrogen to ammonia efficiently. The setup was scaled up by Carl Bosch, leading to the first ammonia production plant in 1913.

    What are the downsides of fertilizers?

    • Environmental Impact: While synthetic nitrogen fertilizers have significantly increased food production, they have also led to negative environmental effects:
      • Over-fertilization: Excess nitrogen application results in reactive nitrogen being released into the atmosphere, contributing to acid rain and soil degradation.
      • Water Pollution: Nitrogen runoff from agricultural fields enters freshwater and coastal ecosystems, leading to eutrophication, which causes oxygen depletion and harms aquatic life.
      • Human Health Concerns: High nitrogen levels in drinking water can pose health risks.
    • Socio-Economic Challenges: Despite increased food production, issues such as starvation, malnutrition, and unequal food distribution persist, highlighting that technological solutions like fertilisers are insufficient; social and political action is also needed.

    Way forward: 

    • Promote Sustainable Fertilizer Use: Encourage the adoption of precision agriculture techniques, such as soil testing and site-specific nutrient management, to optimize fertilizer application. This approach minimizes over-fertilization, reduces nitrogen runoff, and mitigates environmental damage.
    • Strengthen Policy and Regulatory Frameworks: Governments should implement and enforce policies to regulate nitrogen fertilizer use, ensuring that environmental safety standards are met.

  • Mycobacterium Tuberculosis Bacteria

    Why in the News?

    • Due to increasing antimicrobial resistance in Mycobacterium tuberculosis (Mtb), many existing antibiotics are becoming less effective.
      • As a result, researchers are studying Mtb to identify key proteins and design new drugs to target them.

    What is Mycobacterium tuberculosis (Mtb)?

    • Mtb is the bacterium that causes tuberculosis (TB), affecting the lungs and sometimes spreading to other organs.
    • It spreads through airborne droplets from coughing or sneezing by an infected person.
    • Mtb can remain dormant in the body for years without causing active disease.
    • It infects macrophages, immune cells designed to destroy invaders, but instead, Mtb survives and multiplies inside them.

    What do various studies say?

    • A 2024 CSIR-CCMB study showed that Mtb uses cysteine synthase enzymes to survive oxidative stress.
    • A 2017 Karolinska Institute study identified 71 compounds that inhibit these enzymes, improving the effectiveness of antibiotics like isoniazid.
    • Researchers found that Mtb’s ability to evade the immune system is due to its long evolution with humans.
    • Other studies focus on Mtb’s phosphate and carbon metabolism, critical for its survival in hostile environments.
    • Ways for effective medicine development:
      • Target enzymes like CysK2 and CysM to weaken Mtb’s defence mechanisms.
      • Study Mtb’s metabolic pathways to identify vulnerabilities for new drug development.
      • Explore how Mtb develops antibiotic resistance and find ways to overcome it.
      • Investigate how Mtb evades immune responses by manipulating immune cells.
