Evergreen Agriculture: a robust approach to sustainable food security in Africa
Producing more food for a growing population in the coming decades, while at the same time combating poverty and hunger, is a huge challenge facing African agriculture. The risks that come withExpand
Predicting field performance of five irrigated tree species using seedling quality assessment in Burkina Faso, West Africa
The results showed that root collar diameter and DQI appeared to be the most appropriate indicators to predict the outplanting performance of the five tested species in a short-rotation irrigated plantation in semi-arid Burkina Faso. Expand
Cereal yield response to conservation agriculture practices in drylands of West Africa: A quantitative synthesis
The study revealed significant variability in cereal yield response (and hence risk) with all the practices examined, and calls for more understanding of the processes and application of appropriate tree management to reduce crop yield losses while still providing products and services for long-term sustainability of the production systems in drylands of West Africa. Expand
Targeting perennial vegetation in agricultural landscapes for enhancing ecosystem services
Abstract Over the past century, agricultural landscapes worldwide have increasingly been managed for the primary purpose of producing food, while other diverse ecosystem services potentiallyExpand
Millet production under pruned tree crowns in a parkland system in Burkina Faso
It was concluded that at least in the short term millet production could be improved by crown pruning of both karité and néré, but long term effects may depend on the ability of the trees to maintain the amelioration of soil fertility and on how quickly the trees recover from pruning. Expand
Intermediate tree cover can maximize groundwater recharge in the seasonally dry tropics
It is found that moderate tree cover can increase groundwater recharge, and that tree planting and various tree management options can improve groundwater resources. Expand
The effect of trees on preferential flow and soil infiltrability in an agroforestry parkland in semiarid Burkina Faso
The findings from this study demonstrate that trees have a positive impact on soil hydraulic properties influencing groundwater recharge, and thus such effects must be considered when evaluating the impact of trees on water resources in drylands. Expand
Field-scale modeling of tree–crop interactions: Challenges and development needs

  • 1 February 2016
This work states that a model that is flexible enough to simulate any agroforestry system globally should be able to address competition and complementarity above and below ground between trees and crops for light, water and nutrients. Expand
Hydraulic redistribution study in two native tree species of agroforestry parklands of West African dry savanna
Abstract Hydraulic redistribution (HR) in karite ( Vitellaria paradoxa ) and nere ( Parkia biglobosa ) tree species was studied by monitoring the soil water potential ( ψ s ) using thermocoupleExpand
Advances in knowledge of processes in soil–tree–crop interactions in parkland systems in the West African Sahel: A review
Abstract The ‘parklands’ that form the most widespread farming systems in the Sahelian zone of West Africa are farming systems in which annual crops are grown under scattered trees preserved from theExpand
