I. Introduction
a. The different aspects of the concept of cropping system under the tropics.
b. Natural factors influencing the performances of the tropical cropping systems.
c. Consequences of the clearing and the cultivation of a plot with ploughing of the soil under the tropics.
d. Main cultivation practices permitting a sustainable management of the tropical cropping systems.

II. Case study of cropping systems representative of semi arid low-, mid-, and highland tropical areas.

III. Case study of cropping systems representative of sub-humid low-, mid-, and highland tropical areas.

IV. Case study of cropping systems representative of humid low-, mid-, and highland tropical areas.

Horticultural production

The objective of the course is to describe the horticultural systems in tropical regions and to propose factors of phytotechnical improvement for a sustainable development. It explains the importance, diversity and limits of horticultural culture in tropical regions and proposes improvements of production systems, namely -specific and varietal aspects, -technical aspects, -limitation of post harvest losses via a survey of representative cases

Learning outcomes of the course :  
Food-producing and Industrial Crops

Presentation of case studies allowing to better understand the factors influencing the management of traditional cropping systems under the tropics (food-producing and industrial crops) and to choose the production practices to implement in order to improve their performances while assuring a sustainable exploitation of the environment.
At the end of the course, the student must be able:
To understand the factors influencing most the sustainability and the performances of the traditional cropping systems of the main agro-ecological zones met under the tropics (Sahelian, Soudanian, Guinean and tropical mountainous zones).
To distinguish the main tropical cropping systems according to their characteristics.
To identify the production practices that are best adapted to improve the performances and assure the sustainability of the traditional cropping systems under the tropics.

Horticultural production

After completing the course, the student is expected to argue about research criterias concerning horticultural species, varieties, and phytotechnical practices in relation to tropical conditions adaptation and to discuss about applications that allow to limit post harvest losses

Assessment methods and criteria :  
Food-producing and Industrial Crops

Evaluation on the basis of a written feed-back presented at the end of the course.
The evaluation criteria are as follows:
  • the scientific quality of the document,
  • the relevance of the diagnosis carried out in relation to the cropping system analysed,
  • the relevance of the improvements proposed, their originality and their feasibility (quantified proposal vs only suggestions),
  • quality of the references used (recent? scientific? relevant?),
  • the quality of the document (use the standards for a MSc thesis).
