1. Describe Environmental Assessment with the necessity of Environmental assessment in the developing country like Nepal in briefly?

Environmental Assessment (EA) is a process of identifying, predicting, evaluating and mitigating the potential environmental impacts of a proposed development project.

In developing countries like Nepal, EA is necessary to:

  • Ensure sustainable development and reduce negative impacts on the environment.
  • Prevent or minimize environmental degradation and protect natural resources.
  • Involve the public in decision-making and increase transparency.
  • Comply with international environmental standards and regulations.
  • Promote social and economic development while protecting the environment.

2. Nepal is poor country and EIA increase the cost. Justify for or against the statement with examples.

The statement that “Environmental Impact Assessment (EIA) increases the cost in Nepal, a poor country” can be argued for or against, as discussed below:

Argument for the statement:
  • Inadequate funding: Developing countries like Nepal may lack sufficient financial resources to conduct a comprehensive EIA, leading to increased costs. This is because the process requires the engagement of various experts, collection and analysis of data, public consultations, and monitoring of environmental impacts, which may be costly.
  • Delayed implementation: The EIA process can cause delays in project implementation, which may also increase costs due to additional expenses incurred during the extended project timeline.

Example: The proposed construction of the Nijgadh International Airport in Nepal has faced opposition from environmentalists and local communities who cite concerns about deforestation, wildlife habitat loss, and air pollution. The EIA process for the project has been delayed due to lack of funding and technical expertise, which has caused project costs to increase.

Argument against the statement:
  • Long-term benefits: EIA can help identify potential environmental risks and provide recommendations to minimize impacts, which can lead to long-term benefits, such as reduced cleanup costs, enhanced project sustainability, and improved environmental and public health outcomes.
  • Attracting funding: EIA can also help attract funding from international donors or financial institutions by demonstrating that a project is environmentally sound, socially responsible, and economically viable.

Example: The construction of the Upper Trishuli-1 Hydroelectric Power Project in Nepal was supported by the Asian Development Bank, in part because of the thorough EIA conducted for the project, which identified and mitigated potential environmental impacts, and demonstrated the project’s sustainability and potential economic benefits.

Environmental Impact Assessment (EIA) is a process of identifying and evaluating the potential environmental impacts of a proposed development project. In Nepal, a developing country, there is a need for EIA to ensure sustainable development and protect the environment.

Regarding the statement that EIA increases the cost, it is true that conducting an EIA involves costs such as hiring experts, conducting studies, and gathering data. However, the benefits of EIA outweigh the costs in the long run. Here are some examples:

  • EIA can help prevent costly environmental damages in the future, such as soil erosion, landslides, and water pollution, which can have significant economic and social impacts.
  • EIA can identify cost-effective measures to mitigate negative impacts on the environment, such as reforestation or wastewater treatment, which can save costs in the long run.
  • EIA can increase transparency and public participation, which can reduce project delays and conflicts, saving time and money in the long run.
  • EIA can improve the project’s reputation, leading to increased investment and tourism opportunities, which can benefit the economy in the long term.

In conclusion, while it is true that EIA can increase costs in Nepal, it is also important to consider the long-term benefits and the potential to attract funding and support for environmentally sound and sustainable development projects.

  • Increased traffic congestion, noise pollution, and air pollution due to increased traffic flows.

It is important for an Environmental Impact Assessment (EIA) study to identify and assess both the beneficial and adverse impacts of a project, and develop appropriate mitigation measures to minimize the adverse impacts and enhance the beneficial impacts.

13. What is the significance of screening in Environmental assessment? What do you understand by threshold in Environment Assessment?

  • Screening is the initial step in Environmental Assessment (EA) process.
  • Its significance lies in identifying whether a proposed project or activity is likely to have significant environmental impacts that require a full Environmental Impact Assessment (EIA) study or whether the impacts are minimal and require only an Initial Environmental Examination (IEE) study.
  • Screening helps to identify projects that are likely to have significant environmental impacts early in the project development process, allowing project developers to consider alternatives or modifications to the project design that can avoid or minimize adverse environmental impacts.
  • Thresholds are specific criteria or standards that are used to determine whether the environmental impacts of a proposed project or activity are significant enough to require a full EIA study.
  • Thresholds can be based on various factors such as the size, nature, location, and potential impacts of the project.
  • If the proposed project meets or exceeds the threshold, then it is deemed to have the potential for significant environmental impacts, and a full EIA study is required.
  • If it falls below the threshold, then it may be eligible for an IEE study or may not require any further assessment at all.

14. What do you mean by mitigation measures? Describe the necessity of avoidance minimization and compensation in Environment Assessment? Give examples.

Mitigation measures are actions taken to avoid, minimize or compensate for adverse environmental impacts of a proposed project.

  • Avoidance: Avoidance measures aim to eliminate or prevent environmental impacts by altering the project design or locating the project in a less sensitive area. For example, avoiding construction in areas of high biodiversity, or avoiding sensitive cultural or historical sites.
  • Minimization: Minimization measures aim to reduce the severity or magnitude of environmental impacts through the project design or operation. For example, using noise barriers to reduce noise impacts or using low-emission vehicles to reduce air pollution.
  • Compensation: Compensation measures aim to offset the residual environmental impacts that cannot be avoided or minimized by restoring or enhancing the environment elsewhere. For example, compensating for the loss of wetlands by creating new wetlands in another area.

The necessity of avoidance, minimization and compensation measures in Environmental Assessment (EA) is to ensure that the proposed project does not cause irreversible harm to the environment and communities.

  • Avoidance measures can help to prevent significant environmental impacts from occurring in the first place.
  • Minimization measures can help to reduce the severity or magnitude of impacts that cannot be avoided, reducing the overall environmental damage.
  • Compensation measures can help to offset the residual impacts that cannot be avoided or minimized by restoring or enhancing the environment elsewhere, ensuring that the project has a net positive impact on the environment.

Examples of mitigation measures include:

  • Avoiding sensitive areas like wetlands, cultural heritage sites or habitats of endangered species.
  • Installing noise barriers or designing sound-proof buildings to reduce noise pollution.
  • Using low-emission vehicles or designing energy-efficient buildings to reduce air pollution and greenhouse gas emissions.
  • Creating new habitats or restoring degraded ecosystems to compensate for habitat loss.
  • Providing financial compensation or alternative livelihoods to communities affected by the project.

15. EIA report is backbone of the project development. Justify the requirement and necessity of good EIA report.

The Environmental Impact Assessment (EIA) report is a crucial component in the project development process, as it provides critical information regarding the potential environmental impacts of a proposed project. A well-prepared EIA report is necessary to ensure that the project is designed and implemented in an environmentally sound manner.
