Course Objectives
Sustainable utilization of natural resources in tropical agriculture requires an in-depth and a holistic understanding of the diverse tropical bio-physical conditions. The course objectives are:
· Provide basic knowledge of the bio-physical environment of important tropical agro-ecosystems with a focus on soil, water and plant nutrient characteristics, processes and interactions.
· Establish a basis for the more specialised MSc courses on tropical agriculture and natural resources management.
 
Course Contents
Following the course objectives, the course content emphasises on the natural science foundation for further and more specialised studies on Tropical Agriculture with a focus on the fundamental natural resources for agriculture: soil, water and nutrients.

The course has four main elements, covered by lectures and exercises:
· Introduction: Soil, water and nutrients (SWN) as basic natural resources; tropical farming and land use systems; land degradation; and integrated natural resources management.
· The Bio-Physical Environment incl. (i) Pedology: tropical soils, formation, characteristics, classification and catenae. (ii) Agro-hydrology: climate, hydrological cycle, agro-ecological zones, soil erosion, soil and water management. (iii) Plant nutrition: availability and requirement, organic matter turnover, N-fixation, bio-availability, N-fixation and uptake.
· Integrated SWN Management: soil and water management, fertilisers, cropping systems and agroforestry.
· Themes: soil acidity; soil salinity; soil erosion; water use efficiency; nutrient balances; soil fertility and capability.
In the course of the lectures and exercises and group work, important agro-ecosystems are discussed and analysed in terms of the bio-physical environment and natural resources utilisation, with a focus on the following zones:
· Humid zone: lowland wetland, flood plains incl. Coastal zone; rainforests
· Semi-arid zone: rain fed Africa and South-America (Acid and non-acid savannah), rain fed Indian sub-continent (red soils and black soils areas); irrigated areas (Africa and Asia)
· Highlands zone: East Afrcan Highland; Himalaya; South-east Asia; Andean range.
 
Teaching And Learning Methods
Lectures and theoretical exercises, and group work including the preparation of a report on a selected topic. Participation in the exercises and group work is considered essential for successfully completing the course.
