Selective Co-Cultivation of Some Crops Offers Multiple Benefits

Ancient Agricultural Practices and Their Timeless Relevance

While advancements in science and technology have revolutionized modern agriculture, ancient farming practices continue to hold significant value.
Practices like crop rotation and terracing remain integral to sustainable agriculture today.
One such ancient practice, Milpa, originating from the Mayan civilization, is still employed in Mexico and Central America.
Milpa involves co-culturing maize, beans, and squash—dubbed the “three sisters”—to enhance crop yield.
Scientifically, this method demonstrates remarkable synergy: beans fix nitrogen in the soil, maize provides structural support for beans, and squash retains soil moisture and suppresses weeds.

Scientific Insights into the “Three Sisters” System

Recent studies, including one highlighted in Science (August 30, 2024) and later in Agriculture, Ecosystem, and Environment (September 2024), reveal that the benefits of the three-sisters system extend beyond resource sharing.
These crops also interact to reduce pest damage. Maize emits volatile chemicals when attacked by pests, which not only increase toxin levels in its own leaves but also in neighboring plants.
Moreover, maize signals nearby beans to secrete sugar-rich nectar, attracting ants and wasps.
These insects act as natural pest controllers, feeding on or parasitizing caterpillars like the army worm, thus protecting both beans and maize.
Enhanced nectar sugar concentration also extends the lifespan of these beneficial insects, amplifying pest control.

Mixed Cultures vs. Monocultures

Experiments by entomologists demonstrate that crops grown in monoculture are more vulnerable to pests and yield less compared to mixed planting systems.
Their findings suggest that mixed cultures reduce reliance on chemical pesticides, offering a more sustainable and profitable alternative.
According to ecologists, this research underscores the benefits of biodiversity in agricultural systems, emphasizing the importance of integrating crop diversity into farming practices.

Challenges and Future Directions

Despite the benefits, not all crop combinations are successful. The effectiveness of mixed cultures depends on factors such as plot size, weather conditions, pest populations, and the types of volatile compounds emitted by the plants.
Research highlights that complex terpenoids among these compounds play a critical role in inter-plant communication and pest deterrence.
Identifying optimal crop pairings and their biochemical interactions can help farmers achieve better yields while minimizing the use of chemical fertilizers and pesticides.

2024 Noble Prize in Medicine

Revolutionizing Gene Regulation

The Nobel Prize in Physiology or Medicine 2024 was awarded to Victor Ambros and Gary Ruvkun for their groundbreaking discovery of microRNAs (miRNAs) and their role in post-transcriptional gene regulation.
Their research has significantly enhanced our understanding of how genes are expressed and regulated, shedding light on processes crucial for cellular function and development.
These findings promise profound implications for medicine, agriculture, and evolutionary biology.

Understanding Gene Regulation

Gene regulation, the process of turning genes on or off, determines how cells with identical DNA exhibit diverse functions. Traditionally, gene regulation was understood to occur at two levels:

Transcriptional regulation, where transcription factors control the copying of DNA into messenger RNAs (mRNAs).
Epigenetic modifications, involving chemical changes to DNA that influence gene expression.

The discovery of microRNAs introduced a third dimension: post-transcriptional regulation, where microRNAs inhibit the production of proteins from mRNAs, rather than interfering with the transcription process itself.

The Discovery of MicroRNAs

Ambros and Ruvkun’s pioneering research began in the late 1980s with studies on the tiny nematode worm C. elegans.
They discovered that the lin-4 gene produced a small RNA molecule that regulated the lin-14 gene by binding to its mRNA and blocking protein production.
This mechanism, termed post-transcriptional gene regulation, marked the first identification of microRNAs as novel regulators of gene expression.
Initially dismissed as a phenomenon unique to C. elegans, the discovery of the let-7 microRNA, present across species, validated the universal significance of microRNAs, catalyzing further research.

How MicroRNAs Work

MicroRNAs are produced through a multi-step process:

Initiation in the nucleus: RNA polymerase II copies microRNA genes into pri-miRNAs.
Processing by Drosha: Pri-miRNAs are chopped into smaller pre-miRNAs.
Export to cytoplasm: Pre-miRNAs move out of the nucleus via exportin 5.
Final processing by Dicer: Pre-miRNAs are processed into mature microRNAs, which then bind to the RNA-induced silencing complex (RISC) to inhibit specific mRNAs or degrade them.

This intricate process ensures precise regulation of protein production, vital for cellular and developmental functions.

Impacts of MicroRNA Discovery

MicroRNAs play essential roles across diverse biological processes:

Disease Insights: Imbalances in microRNAs are linked to diseases like cancer and Alzheimer’s. MicroRNAs can inhibit or promote cancer cell growth, and specific ones contribute to amyloid protein buildup in Alzheimer’s.
Medical Applications: Synthetic microRNAs are being tested as therapies, and their use as biomarkers shows promise for non-invasive disease diagnosis.
Agricultural Advancements: MicroRNA research is revolutionizing agriculture. Genetically modified farm animals produce allergen-free milk, while crops are being developed to be climate-resilient and productive.
Evolutionary Insights: MicroRNAs, conserved across species, provide critical clues to evolutionary processes, reflecting their fundamental role in life’s basic metabolism.

Global Warming: Is Geo engineering the solution

Global Warming and the Urgency for Action

The United Nations Environment Programme’s 2022 report, The Closing Window, confirmed a sobering reality: achieving the goal of limiting global warming to 1.5°C above pre-industrial levels is now nearly impossible based on current 2030 commitments.
The alternative goal of 2°C is attainable only if all nations adhere to their net-zero pledges—an uncertain prospect given the ongoing trends.
Even halting carbon dioxide emissions today would not immediately reverse warming due to the long-lasting effects of accumulated greenhouse gases.
Moreover, surpassing 1.5°C risks triggering tipping points in the climate system, such as the sudden release of carbon dioxide and methane from thawing Arctic permafrost.
These challenges underscore the necessity of not only halting global warming but actively reversing it.

Traditional Approaches and Their Limitations

Efforts to mitigate climate change, such as reforestation, transitioning to renewable energy, and creating emission-free industries, have progressed but remain insufficient to meet the urgent timeline.
While essential, these measures are slow to produce the necessary results. This has prompted scientists to explore geo-engineering—technological interventions designed to mitigate or reverse climate change on a global scale.
These strategies include increasing the Earth’s solar reflectance and removing carbon dioxide from the atmosphere.

Enhancing Solar Reflectance

Geo-engineering methods aimed at reducing the Earth’s heat absorption focus on increasing solar reflectance.

Stratospheric Aerosol Injection: This method involves dispersing sulphate aerosols into the stratosphere to scatter sunlight and reduce global temperatures, mimicking cooling effects observed after volcanic eruptions like Mount Tambora (1815) and Mount Pinatubo (1991). While simulations show promising results, large-scale implementation remains untested.
Albedo Enhancement: Techniques include marine cloud brightening, spraying seawater to increase cloud reflectivity, and whitening urban surfaces like rooftops and pavements to reflect sunlight.
Space Reflectors: Proposals include deploying millions of reflective objects beyond Earth’s stratosphere to deflect sunlight, potentially reducing global temperatures by 2-4%.

These methods, while innovative, require further refinement and testing before large-scale application.

Removing Carbon Dioxide from the Atmosphere

Carbon dioxide removal focuses on extracting atmospheric CO₂ and securely storing it.

Carbon Burial: This involves capturing CO₂ from industrial emissions and storing it underground or in deep oceans. While promising, risks include leaks and storage instability.
Ocean Liming: Adding calcium or sodium hydroxide to oceans could enhance their CO₂ absorption capacity.
Ocean Fertilisation: Introducing nutrients like iron to stimulate phytoplankton growth, which absorbs CO₂, could sequester carbon at the ocean floor.
Direct Air Capture: Using “artificial trees” or scrubbing towers to chemically remove CO₂ from the air offers potential for large-scale sequestration.

Despite their potential, these methods are resource-intensive and carry ecological risks that must be carefully evaluated.

Risks and Challenges of Geo-Engineering

While geo-engineering offers groundbreaking solutions, it is fraught with risks. Stratospheric aerosol injection could alter precipitation patterns, reduce crop yields, and increase acidic rain, exacerbating existing ecological challenges.
Space reflectors might inadvertently accelerate Arctic ice melting. Ocean-based methods, like fertilisation and liming, could disrupt marine ecosystems.
Additionally, carbon burial and air capture face long-term storage challenges.

These uncertainties highlight the need for extensive testing and monitoring before deploying geo-engineering solutions on a global scale.

The Case for Nature-Based Solutions

Despite the promise of geo-engineering, the safest and most sustainable approach remains large-scale afforestation and marine ecosystem restoration.
Reforestation could sequester up to 85 gigatons of CO₂ by 2050, while protecting marine ecosystems enhances their natural carbon capture capabilities.
These methods are proven, low-risk, and essential complements to any technological interventions.

Despite its low mercury concentration, the massive scale of coal combustion in power plants leads to significant emissions.
India’s dependency on coal for approximately 70% of its electricity generation contributes to over 100 tonnes of mercury emissions annually.

Mercury Emissions in Power Plants

When coal is combusted in power plants, mercury is released in various forms—elemental, oxidized, and particulate mercury—depending on factors like coal quality and pollution control systems.
Elemental mercury is especially concerning due to its stability and long travel range, impacting environments far from the source.

Measures Under the Minamata Convention

The Minamata Convention outlines measures to reduce mercury emissions, including quantified goals, emission limits, multi-pollutant control strategies, best practices, and alternative reduction techniques.
In India, efforts to comply include developing technologically advanced power plants, closing older facilities, and adopting air pollution control devices (APCDs).

Technologies for Mercury Control

Technologies like Electrostatic Precipitators (ESP) and Flue Gas Desulfurization (FGD) help control mercury emissions indirectly.
SCR (Selective Catalytic Reduction) converts elemental mercury into a removable form, while Activated Carbon Injection (ACI) directly adsorbs mercury.
Although promising, many of these technologies are still under development or implementation in India.

Present Scenario in India

India has introduced new environmental norms, including a mercury emission cap of 0.03 mg/Nm³ for power plants.
Most plants are equipped with ESPs for particulate mercury control, while FGD installations are progressing.
The energy sector is gradually shifting toward cleaner technologies like supercritical boilers and renewable energy, reducing dependence on coal and associated mercury emissions.

Challenges and the Way Forward

Despite progress, several challenges persist, such as delays in installing pollution control devices like FGDs, high implementation costs, and reliance on coal.
Renewable energy, while expanding, cannot yet meet India’s energy demands. To mitigate mercury pollution effectively, stricter emission limits, efficient monitoring, timely installation of control devices, and stronger enforcement of environmental regulations are crucial.
These measures will protect public health and the environment from mercury’s harmful effects.
