The UN Convention to Combat Desertification (UNCCD) recently published the “Global Land Outlook Thematic Report” on Rangelands and Pastoralists, revealing that up to 50% of Rangelands are degraded.
About UNCCD:
UNCCD adopted in 1994 (effectively from 1996), is a legally binding agreement that aims to protect and restore land and combat desertification and drought.
It is one of the three Rio Conventions (the other two being – the Convention on Biological Diversity (UNCBD) and United Nations Framework Convention on Climate Change (UNFCCC)).
What is the Rangeland?
Rangeland, is any extensive area of land that is occupied by native herbaceous or shrubby vegetation which is grazed by domestic or wild herbivores.
It may include tallgrass prairies, steppes (shortgrass prairies), desert shrublands, shrub woodlands, savannas, chaparrals, and tundras.
These lands constitute 54% of all land cover, account for 1/6th of global food production, and represent nearly 1/3rd of the planetâs carbon reservoir.
World areas that are most acutely affected by Rangeland Degradation:
Central Asia, China, Mongolia: The replacement of government management with privatization and agricultural industrialization led to the abandonment of herders and reliance on insufficient natural resources, causing degradation.
North Africa and the Near East: Climate change is pushing pastoralists into poverty and degrading rangelands.
Sahel and West Africa: Conflict, power imbalances, and border issues have disrupted livestock mobility, leading to degradation.
South America: Climate change, deforestation from industrial agriculture, and land use conversion are primary drivers of degradation.
East Africa: Migration and forced displacement due to competing land uses are evicting pastoralists, causing degradation.
North America: Degradation of ancient grasslands and dry rangelands threatens biodiversity in ecosystems like tall-grass prairies and southern deserts.
Europe: Policies favoring industrial farming over pastoralism and misguided incentives are causing the abandonment and degradation of rangelands.
South Africa and Australia: Afforestation, mining, and land conversion are causing degradation and loss of rangelands.
How does it impact the Food chain?
Over two billion people, including small-scale herders, ranchers, and farmers, depend on healthy rangelands for their livelihoods, underscoring the critical link between rangeland health and food chain cycle.
Up to 50% of rangelands are degraded due to various factors including overuse, misuse, climate change, and biodiversity loss, posing a severe threat to food security.
The Economic significance of Rangelands:
Livestock Grazing and Agriculture: Rangelands are crucial for livestock production, providing natural forage for cattle, sheep, goats, and other herbivores. This grazing land supports the meat and dairy industries, which are vital to the global food supply and rural economies.
Eco-tourism and hunting: These areas support a wide range of wildlife, contributing to biodiversity and offering opportunities for eco-tourism and hunting, both of which generate significant income for local economies.
Ecosystem Services: Rangelands provide vital services like water filtration, carbon storage, and soil preservation, yielding economic advantages through climate regulation and conservation.
Income and employment opportunities: Harvesting these resources provides income and employment opportunities for rural populations. The economic contributions made by different countries are as follows:
Ethiopia: Livestock production from rangelands accounts for 19% of the country’s GDP.
India: Livestock from rangelands contributes 4% to the national GDP.
Brazil: As a major beef producer, Brazil generates one-third of its agribusiness GDP from cattle livestock, producing 16% of the worldâs beef.
What is the innovative approach presented by the UNCCD Report?
The past estimates by UNCCD of degraded rangeland of roughly 25% are significantly underestimated, where the actual loss of rangelandâs health and productivity was potentially reaching up to 50%.
Conceptual Approach: The report outlines a new conceptual approach designed to help policymakers stabilize, restore, and manage rangelands more effectively.
This new approach is supported by detailed case studies from nearly every world region, which provide important lessons from both the successes and failures in rangeland management.
Core Recommendation – Protect Pastoralism: The report emphasizes the importance of protecting pastoralism a traditional, mobile way of life based on pasture-based livestock production as a key strategy for sustainable rangeland management.
Conclusion: Many countries like the U.S. and Canada makingare trying to reintroduce bison, an animal with significant cultural importance to indigenous peoples. This initiative aims to promote rangeland health and enhance food security.

Mentor comment: India, as one of the most vulnerable countries to climate change, faces significant challenges due to rising temperatures, changing weather patterns, and environmental degradation. The impact of climate change is evident in the reduction of monsoon duration and rainfall levels, melting Himalayan glaciers, and rising sea levels threatening coastal regions. These changes pose risks to agriculture, food security, water availability, and overall environmental sustainability in the country. This article presents the reasons behind the relative lack of political focus on climate change in India and the potential implications for the country’s future.
Letâs learn.
–
Why in the News?
Our Indian politics is overshadowed by merely immediate concerns and political agendas while leaving behind the major challenges like Climate Change and addressing its impacts.
This absence stands out even more when we consider the urgent need for sustainable development amidst worldwide environmental challenges.
Current State of Climate Change in India
According to India’s first-ever Climate Change Assessment Report carried out in 2020, the country’s average temperature is expected to rise by 4.4°C by the end of 2100. A decline in monsoon rainfall since the 1950s has already been observed. A 2°C rise in global average temperatures will make India’s summer monsoon highly unpredictable. At 2.5°C warming, melting glaciers, and loss of snow cover are expected to threaten the stability and reliability of northern India’s glacier-fed rivers. Global sea level has risen about 8 inches in the last century, which is expected to nearly double in this century.
The Present Dilemma: Prioritization of Economic Growth
As a developing nation, India prioritizes economic growth and development as a means to alleviate poverty and improve the standard of living for its citizens.
This focus often leads to a trade-off between environmental protection and industrial expansion, with climate change considerations taking a lower priority in the political discourse.
Challenges associated with generating political will and public support for climate action:
Lack of Immediate Visibility: The effects of climate change are often gradually visible to the general public. This lack of immediate consequences makes it challenging for politicians to garner public support for climate action, as voters tend to prioritize issues that directly impact their daily lives.
Competing Priorities and Short-term Thinking: Indian politics is often characterized by a focus on short-term goals and immediate concerns, such as job creation, infrastructure development, and social welfare schemes. Climate change, with its long-term implications, struggles to gain traction in a political landscape dominated by these pressing issues.
Perceived Conflict with Development Agenda: Some politicians and policymakers view climate action as a hindrance to economic development, fearing that it may limit industrial growth and restrict access to energy resources. This perception creates a barrier to implementing comprehensive climate policies.
Lack of Awareness and Education: Despite growing global awareness of climate change, there is still a need for greater education and understanding of the issue among the general public and political leaders in India.
Government Policies to Address Climate ChangeInternational Solar Alliance (ISA):
India collaborates with solar energy-rich countries to promote solar energy utilization and reduce reliance on non-renewable energy sources. One Sun, One World, One Grid Project: This project seeks to provide energy (SDG 7 – affordable and clean energy) to around 140 countries through a common grid that transfers solar power. By promoting solar energy on a global scale, this initiative addresses energy challenges and supports sustainable development. Swachh Bharat Mission: It focuses on cleanliness and sanitation (SDG 6 â Clean Water and Sanitation) across urban and rural areas in India. By ensuring access to sanitation facilities and promoting cleanliness, this initiative contributes to environmental health and sustainability. COP26 Glasgow Summit Commitments: During the COP26 summit, India made significant commitments to combat climate change, including achieving net zero emissions by 2070, meeting 50% of energy requirements from renewable sources by 2030, reducing carbon emissions, increasing non-fossil energy capacity, and decreasing carbon intensity by 2030. (SDG 13 – mitigating climate change).The Climate Action Tracker gives India an overall rating of âHighly Insufficientâ in its policies and actions tracking, based on 2030 projections. Recent Judicial Stance: M.K. Ranjitsinh and Others vs Union of India (March 2024): The Supreme Court of India ruled that the people of India have the right to be free from the adverse effects of climate change by drawing upon Article 21 and Article 14 of the Indian Constitution. Recent Legislations: Some important policies and laws covering the energy sector emerged, which included the National Electricity Plan 2023, the National Green Hydrogen Mission and the Energy Conservation (Amendment) Act, 2022.
The Way Forward: To elevate climate change as a priority in Indian politics, a multi-pronged approach is necessary:
Emphasizing the economic benefits of climate action: Highlighting the potential for green jobs, sustainable development, and long-term cost savings can help align climate action with economic interests.
Promoting public awareness and engagement: Investing in education campaigns and fostering grassroots movements can help raise awareness and generate public pressure for climate action.
Incorporating climate change into political manifestos: Encouraging political parties to include climate change as a key issue in their election manifestos can help mainstream the topic and ensure its prominence in the political discourse.
Fostering cross-party collaboration: Building consensus and cooperation across political parties on climate change can help ensure continuity and long-term commitment to climate action, regardless of which party is in power.
The National Centre for Polar and Ocean Research, Goa, through the Ministry of Earth Sciences (MoES), has organised the meeting, which will be attended by the 56 member countries of the Antarctic Treaty.
What is the Antarctic Treaty Consultative Meeting (ATCM)?
ATCM is the primary forum for discussing and coordinating activities related to the Antarctic Treaty System.
It was established under the Antarctic Treaty, which was signed in 1959 and entered into force in 1961.
It serves as the annual meeting of the parties to the Antarctic Treaty, known as Consultative Parties.
The ATCM adopts legally binding agreements, known as Antarctic Treaty Measures (ATMs), as well as non-binding recommendations on various matters.
Decisions within the ATCM are made by consensus among the Consultative Parties.
The ATCM established the Committee for Environmental Protection (CEP) as a subsidiary body to provide advice and recommendations on environmental matters.
India had last hosted the ATCM in New Delhi in 2007.

The World Bank report, titled “Water for Shared Prosperity,” was released at the 10th World Water Forum in Bali, Indonesia.
It underscores the widening gap in access to water resources and services, exacerbated by factors like population growth, urbanization, and climate change.
Water for Shared Prosperity: Key Highlights of the Report
In 2022, 2.2 billion people lacked access to safely managed drinking water services, while 3.5 billion lacked access to safely managed sanitation.
Over 800 million people globally are at high risk of drought, with double that number living in flood-prone areas.
Low-income countries have seen a regression in access to safe drinking water, with an additional 197 million people lacking access since 2000.
Rural-urban access gaps in low-income countries have remained largely unchanged over the last two decades.
Hotspots in regions like the Sahel, Southeastern Africa, and South and Central Asia experience the highest water stress.
The Democratic Republic of the Congo holds over half of Africa’s total water resources.
About World Water Forum:

A recent study uncovers the origins and evolution of Baobabs, uniquely shaped trees in Madagascar, with species also native to Africa and Australia.
Do you know?
Mandu, in the Dhar district of Madhya Pradesh, is perhaps the only place in India where baobab trees are found in abundance, with an estimated 1,000 trees in the periphery of the town.
Madhya Pradesh state government has plans to apply for a GI (Geographical Indication) tag for the Khorasani Imli or the fruit of the baobab.
A Baobab tree near the Golconda Fort in Andhra Pradesh is believed to be more than 400 years old.
Aside from Mandu, baobab trees have been recorded in Prayagraj (formerly Allahabad) in Uttar Pradesh, Wai in Maharashtra, and some places in Gujarat and Andhra Pradesh.
About Baobab Trees
Baobabs are deciduous trees (that lose their leaves in autumn) belonging to the genus Adansonia. It comprises 8 distinct species:
Adansonia digitata in continental Africa.
Adansonia gregorii in Northwestern Australia.
6 other species endemic to Madagascar.
Baobabs are known for:
Great heights, with some extending up to 50 metres.
Exceptionally long lifespans, going up to 2,000 years.
They have trunks with large circumferences; thin, spindly branches.
Nicknamed âupside downâ trees because their tops resemble uprooted plants turned upside down.
Conservation Status:
âThreatenedâ with extinction according to the IUCN Red List of Threatened Species.
âLeast Concernâ category but still faces threats such as residential and commercial development and livestock farming and ranching.
Importance of Conservation:
The study emphasized the conservation of the baobab as a keystone species:
Keystone species provide essential resources, such as food or shelter, for a guild of animals.
In return, these animals provide essential services, such as pollination or diaspore dispersal.
Why Baobab tree is called the âMother of Forestsâ?
They can store large amounts of fresh water in their extraordinary trunks.
It also allows the baobab tree to produce nutritious fruits even during the driest years.
This makes them true life savers during times when water is scarce.
In local cultures, they are revered for multiple uses:
Edible fruits and seeds.
Seed oil used for cooking.
Bark fibre used for clothing.

A recent study has uncovered the intricate structure of their communication system, which appears to possess a “phonetic alphabet,” offering new insights into the depth of their social interactions.
Sperm whales, the largest toothed whales, utilize a diverse array of vocalizations to communicate, including bursts of clicking noises known as âcodasâ.
About Sperm Whales (Physeter macrocephalus)).
Sperm whales, the largest toothed whales
It has a series of vertical creases or wrinkles on its body and a small, inconspicuous dorsal fin located near the rear of its back.
The sperm whale uses âecholocationâ to navigate and locate prey during these deep dives.
Prey: Sperm whales primarily feed on squid (including the giant squid) sharks and deep-sea fish.
Habitat: Sperm whales are found in deep oceanic waters worldwide, from the equator to the edges of the pack ice in the Arctic and Antarctic.
Behavior: Known for their exceptional diving capabilities, sperm whales can dive to depths of over 2,000 meters (6,560 feet) and stay submerged for up to 90 minutes. They are social animals, typically found in groups called âpodsâ, which can contain up to twenty individuals.
Conservation Status: Listed as âVULNERABLEâ by the IUCN.
Threats cause: Collisions with ships, entanglement in fishing gear, and noise pollution.
Insights from the Study:
Expressivity: The study, which utilized data from Project CETI demonstrated that sperm whale calls exhibit a broader range of expressivity than previously recognized, hinting at a nuanced mode of communication.
Social Dynamics: Like all marine mammals, sperm whales rely heavily on vocalizations as an integral aspect of their social interactions.
Contextual Analysis: The next phase of research aims to decipher the behavioural context surrounding sperm whale vocalizations, shedding light on their potential meanings.
About Project CETI (Cetacean Translation Initiative)
Project CETI is a non-profit, interdisciplinary scientific and conservation initiative on a mission to listen to and translate the communication of sperm whales off the island of Dominica in the Eastern Caribbean.
On May 13, the Supreme Court stated that addressing the “horrible” issue of 3,800 metric tonnes of untreated Municipal Solid Waste (MSW) accumulating daily in the national capital requires moving beyond party politics.
What is the status of Delhiâs SWM system?
Population Growth and Waste Generation:
According to the 2011 Census Data, New Delhiâs population was approximately 1.7 crore. However, this Population is expected to increase to around 2.32 crore.
This increase will lead to a significant rise in waste generation, estimated at approximately 13,000 tonnes per day (TPD), which equates to roughly 1,400 truckloads daily.
Presently, this daily waste generation accumulates to about 42 lakh tonnes per annum. The population is anticipated to reach 2.85 crore by 2031 due to which the waste generation could increase to 17,000 TPD.
Waste Collection: Around 90% of the waste generated in the city is collected by three municipal corporations:
Municipal Corporation of Delhi (MCD)
Delhi Cantonment Board
New Delhi Municipal Corporation
Waste Composition is of major types – Biodegradable Wet Waste (50-55%), Non-Biodegradable Dry Waste (around 35%), and Inert Waste (10% that does not decompose). The total collective capacity of these facilities is about 9,200 tonnes per day (TPD).
Issue of Unprocessed Waste Disposal:Â
The Municipal Corporation of Delhi (MCD) is disposing of 3,800 TPD of unprocessed waste in landfills.
Designated Landfills (Gazipur, Bhalswa, and Okhla) are filled with unprocessed wet and dry waste, leading to significant environmental issues such as methane gas emissions, leachate production, and landfill fires.
The landfills have accumulated a total of 2.58 crore tonnes of legacy waste, covering 200 acres of land.
What are the challenges faced by MCD?
Lack of Waste Segregation at Source: Many households and commercial establishments do not segregate waste. Unprocessed mixed waste enters landfills as a result.
Land Availability for Waste Processing Plants: Waste processing plants require large land parcels (30-40 acres each). Securing such large tracts of land is challenging in Delhi.
Public Awareness and Practices: There is a lack of public awareness regarding proper waste management practices. This leads to littering and improper disposal habits. MCD’s focus shifts to clearing open points rather than processing wet waste.
Inadequate Waste Collection Services: Some areas suffer from irregular waste collection services. This contributes to waste buildup and increased littering.
Illegal Dumping: Waste is often illegally dumped in open areas and water bodies. This increases the pressure on the MCD and requires additional resources for cleanup.
What efforts need to be made by MCD?
Need for a Decentralized Approach: Given the challenges of identifying large land parcels, Delhi will need to partner with its neighboring States to set up a few of these composting plants.
Additionally, the market for organic compost produced from wet waste lies in the neighboring States of Haryana and Uttar Pradesh.
Need to work on Biodegradable Wet Waste: The design capacity for wet waste processing should be 9,000 TPD. This would require at least 18 composting or biogas plants (assuming each plant has a capacity of 500 TPD).
Significant efforts will be needed to identify land, establish composting facilities, and ensure their proper operation to prevent biodegradable waste from reaching landfills.
Need to work on Non-Biodegradable Dry Waste: Approximately 2% of dry waste is recyclable and should be sent to recycling facilities. The remaining 33% of non-recyclable dry waste (plastics, paper, textile waste) can be used as RDF for power generation in waste-to-energy projects.
Coordination Among Stakeholders: Improved coordination between various Municipal Corporations to streamline waste collection and segregation processes by collaborating with private companies and non-governmental organizations is needed to enhance waste segregation and processing efforts.
Conclusion: Already, Biomining Initiative was launched in 2019 by the MCD to reduce the amount of waste. The COVID-19 pandemic interrupted these efforts. Originally planned for completion by 2024, now expected to take an additional two to three years.
