 while medicine was an essential and vital resource such as medicine daily the more scarce it is and the more complicated the context is the more it is an activity that can take a lot of time and the deployment of all other human activities whether it is economic, educational etc We are all tired and in the end we want a better country مثل صندات، كهرباء، شماب، حمو. في المدينة الورالية، يمكننا أن نجد فيما يكون هناك أقل 40 دو. هذه are very important cases in which the lives of people, or all their details, their culture, etc. are really in danger. There can also be cases where, following a conflict, for example, if suddenly there are 10,000 people moving, the quality of the water will suddenly be disastrous and we will start to have epidemics, cholera, etc. This can also be a motivation to intervene on a project. We often have the problem, not only of the realization of the infrastructure, but a lot of their maintenance and management by the communities. The rural areas are not a major political or economic importance, so they tend to be a little neglected by the authorities. The realization of water projects in the middle of the conflict can also contribute to improving the safety of people by reducing distances, which are always a risk factor to provide water for women, for children, not the risks of violence that can be perpetrated against them. To improve the living conditions for the populations is to provide them with a water of correct quality with enough access and to ensure that it can last for years. To make sure that the infrastructure is made hard, there is a technical part on which it must be seen and there is also a social part that implies the communities to ensure that they will be able to manage the project in a sustainable way. In the rural environment, because of the low economic capacity of the communities, to develop suitable technical solutions and one of the themes on which it must be particularly seen. A lot of the communities in the Congo have been very well-respected. We have set up techniques for manual forage that allow us to make up to 20 meters that require very little maintenance. We have a multiplicity of skills in various fields, whether it is in civil engineering, electricity, water, cement, hydrogeology, and we have set up solutions that are adapted to the local context. These are often complex systems that we are going to make for a population that may be quite limited from a few thousand, or even just a few hundred people, but these are people for whom we will really change the life, I think.
