It was the responsibility of the World Bank to monitor the project and ensure that the people of Chad received help from the pipeline. They should have paid more attention to different aspects of the project, for example where the pipeline was laid. By running the pipeline right through Chad's most fertile land, the natives were setting themselves up for failure. Farms were destroyed and trees such as avocado and mango that the natives relied on were cut down. People received money in return to purchase saplings, but that didn't change the fact that most fruit trees take years and years to reach adulthood and actually start producing fruit. The World Bank, which had promised to supervise the project and protect the population, failed enormously. People displaced from their homes were given poorly constructed shacks in exchange for their livelihood. Even though the pipeline generates profits, they are not returned to the people who essentially paid for it with their homes and food supplies. Furthermore, the World Bank was frighteningly suspicious of loans for the project. Both Chad and Cameroon are part of the IDA, which stands for International Development Association. IDA credits and grants are given to the world's poorest countries, but for the pipeline the World Bank alternated IDA loans with IBRD loans, which are given to countries with reasonable income.
