The correct answer is: All of the above.
Land acquisition for industrial projects can be a challenge due to a number of factors, including social and environmental concerns, delays in clearances, and compensation and rehabilitation issues.
Social and environmental concerns can arise when land is acquired for industrial projects that are located in or near populated areas. These concerns can include the displacement of people from their homes and land, the loss of livelihoods, and the impact on the environment.
Delays in clearances can also be a challenge for land acquisition for industrial projects. These delays can be caused by a number of factors, including the need for environmental impact assessments, the need to obtain approvals from multiple government agencies, and the need to resolve land disputes.
Compensation and rehabilitation issues can also arise when land is acquired for industrial projects. These issues can include the need to provide fair compensation to those who are displaced from their homes and land, and the need to provide assistance to those who are affected by the project.
All of these factors can make land acquisition for industrial projects a complex and challenging process.
