Management of environmental and social measures
Within the framework of construction of the Highway Project, several environmental and social studies were undertaken at different phases:
- The environmental and social evaluation of the project undertaken by Buursink in 2006 and available in three volumes :
- Right-of-way
- Resettlement zone
- Restructuring the Pikine Irregulier Sud zone
- The comprehensive environmental study of the impact of the Mbeubeus waste dump on the resettlement area and the characterization of the soil in the resettlement area.
- Comprehensive environmental and social study of the highway stretch
- Environmental and social study of the resettlement area
- Monthly reports on the environmental monitoring of the Malick Sy – Patte d’Oie and Patte d’Oie – Pikine construction works site
As regards the highway stretch, a certain number of impacts were identified with the various improvement measures for positive impacts and mitigating measures for negative impacts.

Impacts |
Improuvement Measures |
|
Construction |
|
|
Income-generating activities for the local populations during the works |
• Promote recruitment locally • Encourage the employment of local workers (term in the contract) • Encourage the conclusion of contracts with youth associations in neighboring districts |
|
Possibility of new jobs with the firm responsible for the management and maintenance of the highway |
• Encourage the use of local SME/EIG by sub-contracting some activities • Support to SME through training and the facilitation of access to credit |
|
Intensification of economic and commercial activities around the work sites (catering, etc.) |
Develop specific areas and organize the activities around the site in the course of the works |
|
Operation |
|
|
The road’s good standard of service |
Ensure the routine and periodic maintenance of road infrastructure |
| Opening up the areas crossed Increase the public transport offer potentials Facilitation of access to urban infrastructure (hospitals, administrative centres) |
Promote the creation of new bus routes (DDD) Create a road network and transportation systems suited to the concerned areas |
|
Environmental protection notably environmental health |
• Improving the security of goods and persons; Improving the living conditions of the populations, notably by restructuring the zone • Set up effective household waste management systems |
|
Improving public health and socioeducational activities |
• Improved access to internal and external health structures through restructuring • Rapid transportation of rescue facilities in case of disaster • Improved access to education and training structures |
