Welcome to Zac Tchoundjeu Foundation (ZTF). The ZTF focusses on different articulations of education ranging from the nursery, primary/secondary schools (IBAY) to the Higher education (IBAYSUP). The latter is made now of three different schools:

  • The Higher Institute of Environmental Sciences (HIES)
  • The Higher Institute of Management and Business (HIMB)
  • The Higher Institute of Computing Sciences (HICS), under developpement.

The description below, focusses on the Higher Institute of Environmental Sciences (HIES). HIES offer the Short Hand Drive (HND), the Bachelor (BSC.) and Master (MSc.) degrees in Climate change, Agroforestry, Environmental Health or  Quality Hygiene & Security (QHSE); Conservation of Biodiversity and Environmental and Social Impact Assessments. Holders of a Bachelor in law are also encouraged to register for a Master of Environmental Law.



Environmental Science is the science that describes and answers the causal-effect relations taking place in the environment. The basis of the knowledge is the science that applies the principles of natural law about the conservation concepts of materials and energy.

When human beings observe their environment, questions arise that incite further observation to get satisfactory answers until a hypothesis is formulated. Based on this hypothesis, steps for research and experiments are arranged and conducted to prove the hypothesis on humans, life, and all the supporting elements of this planet earth.

Matters related to environment are complexed and interconnected. So no single science could help to fully understand and analyse the problems related to the environment. It is believed that to have a good understanding of concerns related to the environments, sciences such as Agroforestry, Climate Change, Environmental Health, Conservation of Biodiversity, Environmental and Social Impact assessments,  should be understood. Luckily these are the key subjects taught by the Higher Institute of Environmental Sciences (HIES).


Increasing of greenhouse gases (GHG) emissions in the atmosphere is raising global concern. This is because these emissions have led to a shift of temperatures, unpredictable weather patterns and sporadic rainfall that has caused heavy floods, among other adverse impacts. As a result, many countries are pursuing various policies and strategies to help mitigate and adapt to climate change. This will require an understanding of the processes that contribute to climate change. This module will introduce learners to the basic science of climate change by focusing on an understanding of global change, concept of climate change, causes of climate change, vulnerability to, and impact of climate change, generation of climate change data, and international dialogues, processes and mechanisms on climate change.

The aim of this subject is to build the learners’ understanding of the basic science of climate change and its application in forestry and other related sectors. Following objectives are targeted during teaching:

  • describe the elements of global change, components of climate systems and concepts of climate change;
  • explain the causes of climate change;
  • explain the impact of climate change in forestry and other related sectors;
  • relate concepts of vulnerability and response to climate change;
  • generate relevant data for climate change; and
  • Interpret international agreements, discussions and conventions on climate change.



Our mission is to develop and transmit knowledge about the links between health and the environment, and to educate scientists and public health leaders who can design science-based policies to address current and future environmental health challenges

Environmental and health related concerns are some of the biggest challenges facing the world today, and the IBAYSUP and partners universities have developed appropriate teaching programs to address these concerns.  As an environmental health sciences graduate, you will be able to play an important role in predicting and protecting the future of our planet and humankind.

Our environment and health are pivotal to today’s world and its future sustainability; health is the focal point of humanity and without proper health systems, our existence would be at stake. Simultaneously, climate change due to global warming, pollution, the depletion of natural resources, infectious diseases, and lifestyle present serious issues that affect our long-term wellbeing. The Environmental Health Sciences was established to provide insight and equip students with the skills required to implement the principles that they learn to really address problems and create solutions to these significant, global issues.

The Bachelor/Master of Science programs in Environmental Health Management and Health Organization Management are accredited by Ministry of Higher Education, under the tutorial academy of University of Yaounde1 (The first public University created in Cameroun). Moreover the scientific background is provided by the University partners such as the University of California Los Angeles (UCLA in USA), the University of Ghent (in Belgium), and the University of Prague in Czech Republic.  With this strategic network, a well-balanced, comprehensive, comprehensive and student-centred education, combining academic and applied learning related to current and future health and environmental concerns is provided to our students. . As a graduate of the HIES, you will have the knowledge and professional skills to meet the needs of the industry in the Congo Basin and internationally. You will have appropriate skills to help face the global health and environmental challenges of current and future generations.

The Master degree in Environmental Health Sciences is a research-oriented/professional degree that includes coursework and the preparation of a thesis or completion of a comprehensive examination and a major written report.  Students may choose to concentrate on one of the following areas of academic focus: air quality; environmental biology; environmental chemistry; environmental health practice and policy; industrial hygiene; toxicology; or water quality. Interdisciplinary research is encouraged. Students in EHS gain a comprehensive understanding of:

The role that the environment plays in human health;

How people are exposed to hazards in the environment;

The outcomes are of environmental exposures at the cellular or organismal level;

The outcomes of environmental exposures are at the level of human populations; and

What the societal implications are of these outcomes;

How to design science-based policies to address current and future environmental health challenges.




As world population increases, the need for more productive and sustainable use of the land becomes more urgent. According to the United Nations, more than 7 billion people populated the Earth in 2011 and this number is expected to go up to 9.3 billion by the mid-century. To meet the demand for food by 2050, production will have to increase by over 60%. These figures, coupled with current problems borne out of past and existing non-sustainable land use practices, provide the case for changing the way we manage lands and our production of agricultural and tree goods.

Thanks to its multifunctional properties, agroforestry is part of the solution to addressing these issues, whether they be environmental, economic or social. Agroforestry systems include both traditional and modern land-use systems where trees are managed together with crops and/or animal production systems in agricultural settings. They are dynamic, ecologically based, natural resource management systems that diversify and sustain production in order to increase social, economic and environmental benefits for land users at all scales. There is a growing body of scientific literature that demonstrates the gains accruing from agroforestry adoption (FAO, 2021).

Simply defined, Agroforestry is the use of trees in farming systems and in rural landscapes to increase productivity, profitability, diversity and sustainability. Agroforestry focuses on fertilizers trees (land regeneration, soil health) and food security (fruit for nutrition), fodder species (feeding smallholder livestock), timber and fuel wood trees for shelter and energy, medicinal plants to combat diseases.

If the most important aspect of Agroforestry is tree integration in the cropping system, the biggest challenge for practitioners is the identification of the type of tree to integrate in agricultural systems. Planting a tree is a long-term investment and no error is accepted for the choice of the tree at the planting moment. Hazardous choice of the tree may have economic consequences and spiritual discouragements in case of a wrong choice. In fact it is very difficult to realize 15-20 years after tree planting that it was a wrong choice. Taking the diversity characterising the tropical forest (at least 600 species) one may easily chose a wrong species at planting time. To avoid this mistake with sometimes heavy consequences, The World Agroforestry Centre had developed with partners a program titled Participatory Tree Domestication (PTD) of high-value fruit trees and medicinal plants of West and Central Africa (Tchoundjeu, 1998; Tchoundjeu et al. 2010; Tchoundjeu e al; 2012).

Tree Domestication:

Put simply PTD refers to the means communities select, propagate and manage high-value indigenous fruit trees and medicinal plants and integrate them in the various farming systems. Species for domestication are mainly selected encompassing indigenous knowledge and genetic selection based on scientific principles. A strong partnership is therefore developed with scientists, civic authorities and private companies. In brief PTD is a farmer driven and market lead process. It focuses on species farmers consume best with high potentials for local, regional and international markets. Key steps of PTD are:

  • Priority setting
  • Selection of plus tree
  • Propagation using appropriate technique
  • Conservation of high value germplasms
  • Tree integration and management in different cropping systems: «The right tree at the right place»


  1. Environmental and Social Impact Assessment (ESIA)

ESIA is a tool for decision-makers to identify potential environmental impacts of proposed projects, to evaluate alternative approaches, and to design and incorporate appropriate prevention, mitigation, management and monitoring measures. Environmental impact assessment cannot be divorced from social impact of the project, hence the latter is considered as a key dimension of the EIA process. Examples of these close interactions can be found in the context of land tenure and rights, rural livelihoods, and traditional practices. The main aim of ESIA is to help ensuring protection, maintenance and rehabilitation of natural habitats and their functions during or after the implementation of a given project. In general the purpose of the ESIA is to assess and predict potential adverse social and environmental impacts and to develop suitable mitigation measures, which are documented in an Environmental and Social Management Plan.



Biodiversity conservation refers to the protection, upliftment, and management of biodiversity in order to derive sustainable benefits for present and future generations. In collaboration with a network of prominent scientists from diverse disciplines and backgrounds, research is conducted in many critical areas, including: the processes important in generating diversity in rainforests, the relationship between ecology and disease, connectivity and conservation of migratory birds, and rainforest restoration in human-dominated landscapes.  In certain cases novel applications and use the latest technologies, ranging from satellite imagery to molecular genomics could be used in the conservation of biodiversity. Biodiversity conservation has three main objectives:

  • To conduct basic and applied biological research incorporating the latest technologies in order to document biodiversity and to understand essential biotic processes that produce and maintain tropical biodiversity worldwide.
  • To help bridge the gap between the academic, government and non-governmental organization (NGO) communities and increase the quality of science in conservation decision-making by disseminating, as widely as possible, research results, interpretations, and potential conservation applications.
  • To maximize the effectiveness of conservation programs by integrating research results with sustainable development/conservation policy and programs appropriate to tropical economies.
  • To offer an international education curriculum, premised upon significant field research experience and the latest technologies targeting undergraduate and graduate-level students.
