Management of environmental and social measures

  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.


Improuvement Measures


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


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

  Global negative impact mitigation measures
