Our mission

Why we exist

The impact of human, industrial, agricultural and development activities affects the ecosystem both positively and negatively, to the point of becoming a global concern that spares no generation.
The need to monitor and regulate has become urgent and has been the subject of numerous national, regional, continental and international conferences aiming to steer every human or industrial action toward a healthy, peaceful and sustainable environment.

Oasis is a direct and committed actor in preserving this shared wealth. OCS Sarl has joined national and international decision-makers to build a healthy, peaceful environment that benefits every generation — doing its part through the services it offers to safeguard and restore the environment and society, in line with the legal duties of consulting firms. As the saying goes, "the fire burns brighter when everyone brings a piece of wood."

Guiding choices and decisions about project sites, monitoring, oversight, and identifying project impacts and risks. We propose measures to mitigate, eliminate or offset these environmental and social impacts, drawing on a range of studies recommended by experts and international legal standards.

Environmental and social assessment is therefore at the heart of everything we do. Our work covers every aspect of environmental protection: waste collection and processing, sanitation, erosion control, climate action, reforestation, and the promotion of agriculture, livestock farming, fish farming and forestry.

As a research and consulting firm, we also support our clients beyond the environmental field:

  1. Designing and developing community projects.
  2. Project evaluation.
  3. Legal and technical support for entrepreneurship, including business plans and other project management tools.
  4. Support in obtaining licences and operating permits for your mining and other projects.
