Prix Christophe Pralong & Prix Olivier Cadot - Call for projects

Would you like to help solve development problems in the world? Propose your humanitarian project and benefit from the financial support of the Prix Christophe Pralong and the Prix Olivier Cadot.

What is the call for projects?

The Prix Christophe Pralong and the Prix Olivier Cadot aim to encourage students to dedicate themselves to development issues in the world by helping them to carry out a project in an emerging country.


The Prix Pralong was founded in 2007 by Ms Sandra Pralong to honour the memory of her husband Christophe, HEC alumni and former President of the HEC Students' Committee (1978-80). It is awarded by the Christophe Pralong Association.

To support the work of the association and to honour the memory of Professor Olivier Cadot, Professor of International Economics and Development (1999-2019), HEC Lausanne and the International Relations Office (SRI) of the University of Lausanne have created in 2021 a second prize to be awarded under the name of the Prix Olivier Cadot.


Endowed with an annual amount of maximum CHF 10,000 each, these prizes are intended to help a student or a group of maximum 3 students to carry out a social, humanitarian, entrepreneurial or academic project in an emerging country. The country must be on the list of Official Development Assistance (ODA) recipients established by the Development Assistance Committee (DAC) of the OECD . The prize money is intended to cover all or part of the travel costs and one to two months' stay in the country.


Each project should be well defined in terms of objectives, modalities, follow-up and viability. Each proposal must also show what meaning the project has for the student, for the target populations and for the knowledge of development problems on the ground. One of the key conditions is that a local stay is necessary to carry out the project. The prize is open without discrimination to bachelor, master and doctoral students from the following universities: UNIL, EPFL, UNIGE, IHEID, UNIFR and UNINE.

Selection and awarding of the prize

Projects are evaluated based on the following criteria: relevance and feasibility of the project in relation to the budget and other constraints, definition of objectives and modalities, sustainability of the desired results and the need for a stay in the country concerned.

Examples of projects

To date, the Prix Pralong has financed projects such as a cereal mill for a village school in Niger, a medicinal plant processing plant in Vietnam, an aid programme in Madagascar, a fundraising campaign for a dispensary, a feasibility study for micro-irrigation in Niger and a sewing workshop for ready-to-wear clothes for export in Ivory Coast.

At the bottom of the page you will find the projects of the latest laureates.


You can send your applications until 15 january 2024!
The project must take place in the summer of 2024 in the country concerned.


The Prix Pralong is open to students∙e∙s in bachelor, master or doctoral studies from all faculties of the University of Lausanne (UNIL), as well as to students∙e∙s from the following universities: EPFL, UNIGE, IHEID, UNIFR and UNINE. At the time of submission, the candidate must therefore be enrolled at a university in French-speaking Switzerland.

Concerning the Prix Cadot, the student, or at least one student in the case of a group, must be registered at UNIL at the time of submission of the project. A UNIL-registered project leader will be appointed from among the members of the group. All candidates registered at UNIL will be considered for the Prix Pralong and the Prix Cadot. All candidates registered outside UNIL will be considered for the Prix Pralong only.


Candidates will be evaluated based on a written submission that they will have proposed before the deadline, according to the modalities explained in the guide for written submission. The selection decision is not subject to appeal.


Note: The participation of the Prize (maximum amount of 10,000.-) in the financing of the project cannot exceed 80% of the total budget. The remaining 20% comes from funds outside the Prize, and is found by the student himself.

Complex-Posttraumatic Stress Disorder in Urban Egypt : Cultural Adaptation and Pilot Testing of an Evidence-Based Treatment Manual.

Nadine Hosny, Cadot Prize laureate, doctoral student in psychology at UNIL in SSP

The project aims to study the cultural and structural aspects related to post-traumatic stress disorder in urban areas of Egypt, where the prevalence of different forms of violence is high.

The project is part of a larger research project that aims to improve the care of people who have been exposed to repeated forms of violence.

Another study is underway, with the same research objectives but looking at this disorder among the refugee population in Switzerland. Running the project in parallel in Egypt and Switzerland will allow two different perspectives on the same topic in two different contexts.

Setting up of rotovators for rent, including transport, to farmers of small parcels.

Fabien Dierckx, Pralong Prize laureate, Master's degree in tourism studies at UNIL in FGSE

The aim of the project is to set up a system of rotovator rental to prepare the soil before planting food crops, i.e. less than one hectare. The target audience is farmers working on small plots. These plots are often difficult to access, which is why the rotovator is a good tool and must therefore be easily transportable.

The project is based on an observation taking into account several aspects:

  • Soil preparation is a physically demanding and even traumatic activity for which there is no equipment available in Togo or in the rest of West Africa.
  • The purchase of a machine, in this case a rotovator, is often a major investment, which is all the more difficult if it is not available on the territory.
  • The means necessary for maintenance are not always available, as is the depreciation required to renew the machine.

The rotovator rental project is based on three pillars:

  1. Providing material support for the start-up of an activity
  2. Generating income
  3. Seeking the involvement of stakeholders in the area concerned

Construction of a borehole equipped with a human-powered pump for a community without access to drinking water in the Mfekout district of Njimom.

Idrissou Mounpe Chare, Pralong Prize laureate, PhD student in Social Sciences in SSP

Access to drinking water and sanitation is a daily challenge for countries in the South, including Cameroon. Household access to drinking water is only 31%, with strong disparities between urban (50.7%) and rural (6.1%) areas.

This is why this project consists of building a human-powered borehole in a rural commune in Cameroon, namely Njimom. Njimom is not connected to the water distribution network. The water quality is poor because the available sources are not drinkable. The inhabitants must therefore walk long distances to access water sources whose quality is not always guaranteed, which has many negative consequences for their health.

This project therefore responds to a need to improve the living conditions of poor populations by providing access to an essential basic product, water. This project will also improve hygiene and sanitation among the beneficiary populations for whom the scarcity of water limits hygiene measures.
