A possible link exists between Himalayan region construction lacking supervision and glacier melting and the occurrences of glacial lake bursting (GLOFs).
The construction activities without supervision that include building roads and mining sites and deforestation activities speed up glacier melting rates. These activities can:
-The process of construction generates black carbon emissions commonly referred to as soot while also causing its deposition to rise. The deposition of black carbon on snow and ice surfaces allows the absorption of solar radiation and quickens the melting process.
-Construction work that changes drainage patterns causes problems with meltwater movement and may create situations leading to GLOFs.
Desertification via slope destabilization occurs because construction activities create conditions that permit landslide and debris flow formations which ultimately generate GLOFs.
Glacial Lake Stability Effects:
-The construction process widens glacial lake sedimentation at a higher rate that gradually lifts the lake surface potentially leading to dam failure.
-The building process interrupts moraine dams which leads to their destabilization.
The disturbance of moraines that serve as natural lake dams leads to increased vulnerability for water dam ruptures which results in GLOFs.
The prevention of glacial lake outburst floods demands a multi-dimensional approach that requires three main solutions.
-A comprehensive set of environmental rules needs implementation to manage Himalayan building operations and decrease their ecological impacts.
-A strong surveillance system combined with GLOF prediction capabilities requires establishment to monitor glacial lakes.
-The preparation and reaction to disasters must receive enhanced support because it helps reduce the effects of GLOFs on local populations as well as infrastructure systems.
Economical development practices in the Himalayan region must become sustainable to prevent GLOF risks from increasing.

Model Answer
Introduction
Climate budgeting is essential for integrating climate concerns into India’s development agenda, as it helps identify, classify, and categorize climate-related expenditures within the government’s budgetary structure. This enables accurate estimation, diligent monitoring, and systematic tracking of climate-related finances. However, India currently lacks a specific framework or guidelines to allocate a budget for climate change interventions.
Reasons for Climate Budgeting
1. International Reporting Requirements
Climate budgeting can help India meet its international reporting obligations, such as the Enhanced Transparency Framework (ETF) under the UNFCCC. By tracking climate finance expenditures, India can efficiently report its contributions towards national climate targets in Biennial Transparency Reports (BTR), fulfilling global commitments.
2. Strengthening Climate Finance Frameworks
Integrating climate finance into the budget allows for better identification of eligible projects, enhancing frameworks like green bonds. This, in turn, facilitates investments in climate-friendly initiatives, ensuring that financial instruments align with climate goals.
3. Estimating the Climate Finance Gap
Climate budgeting enables the estimation of the finance gap, providing evidence of existing climate expenditures. For example, Indonesia used climate budgeting to analyze this gap, helping create innovative financial models to address the shortfall.
4. Robust Policy-Making
By quantifying investments required to reduce emissions, climate budgeting aids in prioritizing climate actions. This process supports the State Action Plans on Climate Change, allowing for better management of climate finance and more robust policy decisions.
5. Preventing Underreporting
Climate budgeting helps prevent the underreporting of development projects with significant climate co-benefits. For example, PMKSY (Pradhan Mantri Krishi Sinchayee Yojana), which focuses on water conservation, is not typically reported as a climate adaptation or mitigation initiative.
Conclusion
Several Indian states, such as Maharashtra, Assam, Chhattisgarh, Bihar, Odisha, and Kerala, have already initiated budget coding exercises to track the climate relevance of development projects. This emphasizes the need for a national framework for climate budgeting to improve transparency, accountability, and the effectiveness of climate finance management.

Recovery of the Ozone Layer: Measures and Impact
Recent scientific assessments indicate that the ozone layer is projected to heal by 2066, primarily due to international efforts to combat ozone depletion. The ozone layer is crucial for blocking harmful ultraviolet (UV) radiation, which can lead to serious health issues such as skin cancer and cataracts, as well as detrimental effects on ecosystems (World Meteorological Organization, 2021).
Key Initiatives for Ozone Recovery
1. Vienna Convention for the Protection of the Ozone Layer (1985)
This convention laid the groundwork for international cooperation to monitor and protect the ozone layer. It encouraged research on ozone depletion and established a platform for countries to exchange information regarding the production and consumption of ozone-depleting substances (ODS) (United Nations Environment Programme, 1985).
2. Montreal Protocol on Substances that Deplete the Ozone Layer (1987)
A landmark treaty, the Montreal Protocol aimed to phase out nearly 100 ODS, including chlorofluorocarbons (CFCs). This legally binding agreement has been pivotal in reducing the use of these harmful chemicals globally. The Ozone Fund was also created to assist developing countries in their transition away from ODS (UNEP, 1987).
3. Kigali Amendment to the Montreal Protocol (2016)
This amendment focuses on phasing down hydrofluorocarbons (HFCs), which, while not ozone-depleting, are potent greenhouse gases. By targeting HFC reductions, the Kigali Amendment enhances the Montreal Protocol’s role in addressing climate change (UNEP, 2016).
Conclusion
The collaborative global efforts outlined above have significantly contributed to the recovery of the ozone layer. If current policies are maintained, the ozone layer is expected to return to its 1980 levels by 2066 over Antarctica, demonstrating the effectiveness of these measures in protecting both human health and the environment (World Meteorological Organization, 2021). It is essential to continue understanding the interplay between ozone recovery and climate change to ensure long-term sustainability.
