Valuing Soil Conservation Benefits of Agroforestry Practices
Although advocates of agroforestry have promoted soil conservation as one of its primary benefits, empirical estimates of these benefits have been lacking due to temporal and spatial complexity of agroforestry systems and soil resource dynamics. This study aims to reduce this gap by designing and testing a three stage farm level productivity methodology for economic evaluation of soil conservat...
متن کاملIndexing Soil Conservation: Farmer Perceptions of Agroforestry Benefits
Soil erosion poses economic and environmental concerns in many tropical uplands. Agroforestry has been proposed as a sustainable land use that can mitigate soil erosion and promote the economic welfare of small farmers. To evaluate such claims, we must (a) develop a composite measure of effectiveness, such as a soil conservation index, and (b) define it in terms understood by the farmers who ul...
متن کاملPlant-soil interactions in multistrata agroforestry in the humid tropics
Multistrata agroforestry systems with tree crops comprise a variety of land use systems ranging from plantations of coffee, cacao or tea with shade trees to highly diversified homegardens and multi-storey tree gardens. Research on plant-soil interactions has concentrated on the former. Tree crop-based land use systems are more efficient in maintaining soil fertility than annual cropping systems...
متن کاملAgroforestry Influences on Soil Aggregate Stability and Enzyme Activity
INTRODUCTION: The percentage of water stable aggregates (WSA) is a measure of resistance to breakdown by water and mechanical activities. Water stable aggregates improve soil water and air movement. Macro-aggregates (diam. > 250 m) are considered as a secondary soil structure associated with pores, microbial habitat, and physical protection of organic matter (Christensen, 2001; Carter, 2004). A...
متن کاملMeteorology and Agroforestry Meteorology and Agroforestry
The physical environment affects and interacts with agroforestry systems through tree and crop growth, animal performance, management operations and interactions between the tree/shrub and non-tree components (abbreviated to tree/crop interactions). Interactions take place mainly through the media of microclimate, soil moisture and soil. They may have beneficial or adverse effects, for tree and...
