Subject: Conservation & Mitigation

Central Idea

• The global transition towards net-zero emissions is a critical aspect of combating climate change, and electric vehicles (EVs) play a pivotal role in this endeavour.
• In economically developing countries, hybrid EVs offer a significant opportunity to kickstart the transition, considering challenges related to power generation, grid capacity, and fast-charging infrastructure.

Understanding Net-Zero for Vehicles

• “Net-zero for vehicles” refers to the concept of achieving carbon neutrality or net-zero carbon emissions in the transportation sector.
• This goal involves reducing the overall carbon footprint of vehicles to balance the emissions they produce with equivalent carbon removal or offsetting measures.

Types of Electric Vehicles

• Electric Vehicle (EV): Any vehicle using an electric drivetrain powered by a portable electrical energy source.
• Hybrid EV: Combines an internal combustion engine (ICE) with an electrical generator to produce electricity. It utilizes a small battery (1-5kWh) as an energy buffer but cannot be charged from the grid.
• Full EV: Also known as a battery EV or plug-in EV, it lacks an ICE, resulting in no tailpipe emissions. It has a larger battery (20-120 kWh) charged solely from the grid.
• Plug-in Hybrid EV: A hybrid EV with a larger battery (5-15 kWh) that can be charged from the grid, operating in full electric mode as long as there is energy in the battery.
• Fuel-Cell EV: Utilizes a fuel cell and a small battery buffer to produce electricity for the drivetrain.

Fuel Economy and Emissions of Hybrid and Fully Electric EVs

• Hybrid EVs: With the combination of an ICE, generator, and battery, hybrid EVs exhibit 1.5-2x higher fuel economy than conventional ICE vehicles in city driving and 1-1.5x higher in highway driving.
• Plug-in Hybrid EVs: Combine the advantages of hybrid and full EVs, covering 80-90% of short commutes in fully electric mode with 3-4x higher fuel economy than conventional vehicles.
• Life-Cycle Emissions: A comprehensive index considering well-to-wheel emissions, vehicle, and battery production, maintenance, and end-of-life recycling. Full EVs result in 19-34% lower emissions for sedans and 38-49% for SUVs compared to conventional vehicles, even with fossil-fuel-dominated energy mix in India.

Challenges in Transitioning to Electric Mobility

• Fast-Charging Infrastructure: Successful transition requires fast-charging infrastructure along highways to alleviate range anxiety and encourage full EV adoption.
• Grid Access and Reliability: Many regions lack access to a reliable grid, posing challenges for slow and fast-charging capabilities.
• Vehicle Costs: Mass-market EV prices are much lower in economically developing countries, hindering widespread adoption due to high battery costs.

Hybrid and Plug-in Hybrid EVs: Decarbonizing the Interim

• Hybrid EVs present an opportunity to lower emissions until full EVs become viable options in the long term.
• Plug-in hybrids, with their all-electric range, offer many benefits, reducing fuel costs, emissions, and oil imports.
• Regenerative braking and engine start-stop mechanisms improve fuel economy in hybrid EVs.
• Hybrid cars’ purchase price is only slightly higher than conventional vehicles, irrespective of the vehicle range.

Conclusion

• Hybrid Electric Vehicles serve as a bridge to the net-zero future, offering a practical and efficient solution for economically developing countries.
• While full EVs are the ultimate goal, the adoption of hybrid and plug-in hybrid EVs can significantly reduce emissions and fuel costs in the interim.
• A coordinated effort to address infrastructure challenges and enhance grid reliability will pave the way for a sustainable transition towards a net-zero mobility landscape powered by renewable energy sources.

• India’s tiger population has witnessed significant growth over the past decade, owing to successful conservation efforts under the Project Tiger initiative.

Celebrating 50 Years of Project Tiger

• Historical Context: Project Tiger was launched in 1973 to promote the conservation of tigers when their population was alarmingly low, hovering around 2,000 due to hunting and habitat destruction.
• Landmark Achievement: Over the past 50 years, India’s tiger population has made a remarkable recovery, standing at 3,167 in 2022 as compared to just 268 in 1973.

Population Growth and Distribution

• Decade-wise Growth: The tiger population has shown a remarkable growth trajectory in recent years. In 2010, there were 1,706 tigers, which increased to 2,226 in 2014 and further rose to 3,582 in 2022.
• Regional Distribution: In 2022, the states with the highest tiger populations were Madhya Pradesh (785), Karnataka (563), Uttarakhand (560), and Maharashtra (444). Nearly 25% of the tigers were reported outside protected areas.

Conservation Efforts and Successes

• Tiger Reserves: India’s tigers are mainly concentrated in 53 dedicated tiger reserves covering about 75,796 square km, which accounts for approximately 2.3% of the country’s total land area.
• Successful Reserves: Reserves like Corbett National Park in Uttarakhand (260 tigers), Bandipur (150), and Nagarhole (141) in Karnataka have shown commendable success in tiger conservation.
• Project Tiger: Launched in 1973, Project Tiger played a crucial role in conserving the species, ensuring not just the protection of tigers but also preserving their natural habitats.

Challenges and Concerns

• Habitat Fragmentation: The growing human population and developmental activities have led to the fragmentation of tiger habitats, affecting their dispersal and increasing human-tiger conflicts.
• Quality of Forest Cover: The degradation of forest cover can impact prey availability and contribute to human-wildlife conflict, especially in regions like Central India and the Eastern Ghats.
• Human-Wildlife Conflict: As tiger habitats shrink and corridors get disrupted, encounters between tigers and humans have increased, leading to conflicts and potential danger to both tigers and people.
• Legal Framework Dilution: Some proposed amendments to environmental acts and the approval of projects in protected areas have raised concerns about the dilution of the legal framework supporting tiger conservation.

Way forward

• Development with Ecological Sensibility: Upcoming infrastructure projects, like highways, are being planned with safe passageways for tigers and other animals to ensure minimal disruption to their movement.
• Relocation and Rehabilitation: Relocation of human settlements from core areas of tiger reserves is incentivized to increase protected land and improve tribal livelihoods.

Conclusion

• Conservation Commitment: The success of tiger conservation in India has come through the commitment of people, political will, and strong legal and policy frameworks.
• Sustained Efforts: Despite the successes, continued efforts and vigilance are essential to ensure the continued growth of the tiger population and its harmonious coexistence with human communities.

Central Idea

• Amidst the global decline of natural resources and forests, silvopasture systems emerge as a relevant solution to counter deforestation trends.

What is Silvopasture?

• Silvopasture is a sustainable land management practice that integrates trees, forage crops, and livestock grazing on the same parcel of land.
• The term “silvopasture” is derived from the Latin words “silva” (forest) and “pastura” (pasture), emphasizing the combination of forestry and pasture practices.
• In this system, carefully selected trees or tree species are planted or retained on grazing lands or pastures.
• The trees can be scattered throughout the pasture, arranged in rows, or established as windbreaks and hedgerows.
• Livestock, such as cattle, sheep, or goats, graze freely within the area, utilizing the available forage while benefiting from the shade and other advantages provided by the trees.

Advantages offered

Central Idea

• A devastating landslide in Maharashtra’s Raigad district recently resulted in the loss of 27 lives and the destruction of an entire village.
• This tragic incident has reignited discussions about the 2011 Dr Madhav Gadgil report on the conservation of the ecologically sensitive Western Ghats.

Dr Madhav Gadgil Report

• Formation: In 2010, the Western Ghats Ecology Expert Panel (WGEEP), chaired by ecologist Dr Madhav Gadgil, was appointed by Union Environment Ministry.

Key recommendations:

(1) Proposition of ESZs: The report proposed classifying 64 percent of the Western Ghats, spanning six states, into Ecologically Sensitive Zones (ESZ) – ESZ 1, ESZ 2, and ESZ 3, and designating the entire region as an Ecologically Sensitive Area (ESA).

(2) Development Restrictions: The report recommended stopping almost all developmental activities, including mining, construction of thermal power plants, and dams, in ESZ 1. It also called for the phasing out of mining in ESZ 1 in Goa, banning new polluting industries in ESZ 1 and ESZ 2 in Maharashtra’s Ratnagiri and Sindhudurg districts, and implementing zero pollution norms for existing industries.

(3) Sustainable Farming: The report advocated a ban on growing single commercial crops, such as tea, coffee, cardamom, rubber, banana, and pineapple, to promote sustainable farming practices in the Western Ghats.

(4) Establishing a dedicated Authority: It recommended decentralization and granting more powers to local authorities in the governance of the environment. The establishment of a Western Ghats Ecology Authority was proposed to manage the region’s ecology and ensure sustainable development.

(5) Certain prohibitions: The report urged the prohibition of genetically modified crops, plastic bags, Special Economic Zones, and new hill stations, along with the protection of river ecosystems and public lands.

Challenges in Implementation:

• Stakeholder Resistance: The recommendations faced opposition from stakeholder states, fearing negative impacts on development and livelihoods.
• Formation of Kasturirangan Panel: In response to the resistance, a High-Level Working Group on Western Ghats, led by Dr K Kasturirangan, was constituted. This panel’s report, released in 2014, designated only 37 percent of the region as ecologically sensitive, significantly less than Gadgil’s proposal.
• Revision and Splitting of ESZ: The Kasturirangan report divided the Western Ghats into cultural (human settlements) and natural (non-human settlements) regions. It suggested designating cultural lands as ESAs and introduced red, orange, and green categories for activities based on regulation levels.

Controversy and Criticism

• Dr Madhav Gadgil criticized the Kasturirangan report, stating that it distorted and perverted the essence of his panel’s original recommendations.
• He highlighted the importance of including local communities in economic decisions and the need for a more pro-nature approach.

Current Status

• High-Powered Committee: By 2022, the Ministry of Environment, Forest, and Climate Change (MoEF&CC) announced the formation of a high-powered committee to conduct physical landscaping and submit a detailed report within a year.

Conclusion

• The Raigad landslide tragedy and the discussions about the Dr Madhav Gadgil report underscore the significance of preserving the ecologically sensitive Western Ghats.
• The delicate balance between conservation efforts and developmental requirements remains a complex issue.
• It is essential for stakeholders, governments, and experts to collaborate and find sustainable solutions to protect this vital ecosystem and its biodiversity for future generations.
