For community people, the very idea of losing their land creates strong emotions. Add in the complex business process of land acquisition and resettlement and the experience can be very traumatic.
For your company the difference between doing it well and doing it badly will affect the success or failure of your business plan with inadequate attention to the impacts of land access and acquisition likely to lead to disaffected communities and civil society groups taking action. They might choose to do this by lobbying government and holding up permits and approvals or they may take direct action and stop construction and operations.
On the other hand, if the acquisition and resettlement is well managed it can result in positive results for local people, creating benefits such as better quality housing and new livelihood opportunities.
