GY3156 Tropical land management
GY2149 Biogeography or GY2150 Geomorphological processes or GY2152 Hydrology.
The course focuses on the use and management of the land resource in the semi-arid, the seasonal wet-dry and the humid tropics. In particular the course covers:
Tropical weathering: types and products of tropical weathering.
Tropical soils: common soil types of the humid, wet-dry and semi-arid tropics, importance of soil properties (texture, structure, permeability) under agriculture.
Effects of deforestation on humid tropical soil: hydrological change, nutrient depletion, erosion.
Semi-arid soils and land use problems: water management, irrigation and salinisation, erosion.
Desertification: causes, effects on agriculture, management options.
Geomorphology and tropical land management: slope failure, soil erosion, management of geomorphological hazard (soil and water conservation).
Land degradation: causes (physical and human), consequences for livelihoods, assessment and monitoring, management.
Land classification and land capability: planning for effective tropical land management, importance of growing period, agro-ecological zones.
Tropical land management and environmental change: effects of temperature increases on crop viability, changes in rainfall amounts and annual pattern, effect of changing CO2 on plant viability, Caribbean case studies.
Response to changing climates: potential for adaptation of tropical farming systems, importance of indigenous knowledge, intervention and policy issues.
