The Agro-Shrub Alliance is dedicated to promoting sustainable agriculture by harnessing the power of the Optimized Shrub System (OSS) which is a scientifically validated shrub-based farming system that uses the native shrubs Guiera senegalensis and Piliostigma reticulatum. We aim to enhance food security, improve livelihoods, and foster environmental stewardship through innovative research, collaborative partnerships, and the widespread adoption of the OSS technology. By empowering communities and protecting natural resources, we strive to create a resilient and thriving agricultural landscape for future generations of the W. African Sahel. https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1634918842918-B532YU0N2222OT7FOHJB/SBF+Infographic.png Home - The Optimized Shrub System (OSS) Involves increasing the density of the naturally occurring shrubs in farmers’ fields, and incorporating pruned shrub residue into the soil. This results in a cascade of benefits including significantly improved soil quality, improved water and nutrient status of crops, reduced time to harvest by about 15 days, and dramatically increased yields – up to three-fold. https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1537558108715-B74DWWLQC5JM0FSLW5XD/ASA_Graphic_3.png Home - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1537558108715-B74DWWLQC5JM0FSLW5XD/ASA_Graphic_3.png Home - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1537119074043-H67ESJE490ORL96EUW4K/ASA_Graphic_4b.png Home https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1536257656379-02Z0SHST84ESIZYMEM9Y/Guiera+senegalensis.png Home - Guiera senegalensis Guiera senegalensis, pictured left, is native to the northern regions of the Sahel where: The average annual rainfall is 300mm The average annual temperature is 3°c. https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1535481008502-5KDNWU4YXYXC2ZUVWSX4/pilo.jpg Home - Piliostigma Reticulatum Piliostigma Reticulatum, pictured right, is native to the southern regions of the Sahel where: The average annual rainfall is 750mm per year The average annual temperature is 32°c. https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1537120408895-A1R377AI7Z6AAYUUL1XR/ASA_Graphic_1.png Home https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1535480573751-DV1F07Z0GPIPAAFSPTJT/Area+Map.png Home https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1537198205203-07L36BPN9Q4F5AAIF0K9/ASA_Graphic_5.png Home https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1535573253292-8C2W27TP8TU7US5SFVA8/shrub-roots+copy.jpg Home - Bio-Irrigation Deep tap roots lift water from the wet subsoil to the surface (hydraulic lift) where it is released to surrounding crops. https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1535572681981-161VFPURXRK3HBTY2Z4I/farmer-gesturing-to-casava-and-pilio1.jpg Home - Better Soil Shrub intercropping results in increased water holding capacity, soil organic matter and the overall soil health. https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1537124157320-TM24ZVXJKWW7F4EEJONY/increased+soil+organic+matter.jpg Home - Assists Food Crops The shrubs do not compete with crops and they help to create microbial diversity and nutrient availability. https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1536258149056-V9BP8KOZG2EF72EJLN99/millet+with+gueira+plot.jpg Home - Improved Yields This system helps to decrease the days to crop maturity by 15 days. https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1537121510630-HRV4OQJPVYI9EPR3VBNW/Asset+3.png Home https://agroshrub.org/current-situation daily 0.75 2022-10-19 https://images.squarespace-cdn.com/content/v1/5b82eabb620b859f852afe48/1536258317079-4OY5RE7T3AR3ZE1AT196/Firewood+scavenging.jpg Why Shrubs?
