Below-ground interactions in tropical agroecosystems: concepts and models with multiple plant components.

Book cover for Below-ground interactions in tropical agroecosystems: concepts and models with multiple plant components.

Description

This book provides a synthesis of plant-soil-plant interactions from the plot to landscape scale. It focuses on the process level, which is relevant to many types of multispecies agroecosystems (agroforestry, intercropping and others). It also links basic research to practical application (and indigenous knowledge) in a wide range of systems with or without trees, and considers implications of bel...

Soil and water movement: combining local ecological knowledge with that of modellers when scaling up from plot to landscape level.

The current confusion surrounding watershed functions in relation to land use change (specifically deforestation) are analysed, and an analytical framework that can be used to predict relationships between plot-level interventions and landscape-level effects are discussed. Mental models of watershed ecosystems by local farmers are studied and compared them with models developed through a scientific approach, using two case studies. The first one was conducted in Sumberjaya, West Lampung, Indonesia, focusing on erosion and water quality and flow, and the other in Dong Cao catchment, Vietnam, focusing on soil-plant interactions. Some characteristics of two modelling approaches (spatial patterns and hydrological process models) applied to the relationships between land cover and watershed functions are tabulated and discussed.
