Q252. Which specific global initiative aims to restore 350 million hectares of deforested and degraded land by 2030?
Explanation
A global effort was launched to restore hundreds of millions of hectares of degraded and deforested land within a specific timeframe. This initiative brings together governments, private organizations, and local communities to implement restoration projects that benefit both the environment and people. By focusing on the recovery of ecological functions, the program aims to improve biodiversity, enhance food security, and help countries meet their international climate commitments.
Q253. Illegal logging is often driven by the high international demand for:
Explanation
The unauthorized cutting and removal of trees is often fueled by the high value placed on certain types of wood in the global market. These precious materials are highly sought after for making high-quality furniture, flooring, and other luxury goods. Because of the large profits involved, criminal groups often bypass environmental laws and exploit protected forest areas, leading to rapid habitat destruction and the loss of biodiversity.
Q254. How does deforestation contribute to the outbreak of zoonotic diseases?
Explanation
The destruction of natural habitats brings people into closer proximity with wild animals that they would otherwise rarely encounter. As forests are cleared for farming or development, the boundaries between human communities and wildlife become blurred. This increased contact provides more opportunities for pathogens to jump from animals to humans. Such events can lead to the outbreak of new infectious diseases that can spread rapidly through the global population.
Q255. The "Chipko Movement," originating in Uttarakhand, was primarily a grassroots movement for:
Explanation
A historic grassroots movement in northern India focused on protecting trees from being cut down by commercial interests. The participants, mostly women from local villages, used non-violent methods such as hugging the trunks to prevent loggers from using their saws. This action highlighted the importance of forests for the livelihoods of mountain communities and became a powerful symbol for environmental conservation and social justice around the world.
Q256. Environmental Impact Assessment (EIA) is best defined as:
Explanation
Before a major project begins, a formal process is used to predict and evaluate the potential consequences for the surrounding environment. This study considers the likely impacts on air, water, soil, and the health of local communities. By identifying these issues early, developers can find ways to reduce or prevent harm. This assessment is a critical tool for ensuring that new developments are sustainable and socially responsible.
Q257. Regarding the Environmental Impact Assessment (EIA) process in India, consider the following statements:
I. It is statutorily backed by the Environment (Protection) Act, 1986.
II. Public consultation is a mandatory component for all categories of projects.
III. Screening is the first step of the EIA process.
Which of the above statement(s) is/are correct?
I. It is statutorily backed by the Environment (Protection) Act, 1986.
II. Public consultation is a mandatory component for all categories of projects.
III. Screening is the first step of the EIA process.
Which of the above statement(s) is/are correct?
Explanation
The legal framework for assessing the environmental effects of projects in India is based on a major national protection law. The process involves several mandatory stages, beginning with a decision on whether a full study is even required. While many projects involve gathering feedback from the public, some specific types are excused from this step. These assessments are essential for balancing the needs of development with environmental conservation.
Q258. In the Indian EIA framework, "Category A" projects require environmental clearance from:
Explanation
Projects that have the potential for significant environmental impact are classified into a specific group that requires a high level of scrutiny. For these developments, the final decision on whether they can proceed is made at the national level by the central government’s environmental authority. This ensures that large-scale industrial and infrastructure activities are evaluated according to rigorous standards that protect the interests of the entire country and its natural resources.
Q259. Which step of the EIA process determines the terms of reference and the specific environmental issues to be studied?
Explanation
After it is decided that an environmental study is necessary, a specific phase is used to define the boundaries and focus of the investigation. During this stage, experts identify the most important issues that need to be addressed and determine the methods that will be used to collect data. This ensures that the final report will cover all relevant concerns and provide a solid basis for making an informed decision.
Q260. What is the role of the Environmental Management Plan (EMP) within an EIA report?
Explanation
A critical part of an environmental report is a detailed plan that outlines the specific actions that will be taken to manage the project’s impact. This document describes the measures for preventing, reducing, and compensating for any negative effects identified during the assessment. It also includes details on how these actions will be monitored over time to ensure that the project remains in compliance with environmental standards and goals.Answer key for these questions
