Transcript

A Digitally Integrated Africa Soil Information Service (AfSIS)

Grantee institution:The International Centre for Tropical Agriculture (CIAT)

Budget: US$ 18.1 m

Implementing Institution:Tropical Soil Biology & Fertility (TSBF) Institute of (CIAT)

Partners:Columbia University’s Earth Institute

World Soil Information (ISRIC)World Agro-forestry Centre (ICRAF)

5 initial NARS in Africa (Kenya, Tanzania, Malawi, Mali & Nigeria)

22 other African countries

Presentation Outline

• Background• Foreseen Impact• Project Activities• AfSIS Data Systems• Soil Surveys• Fertility trials• Capacity building, user outreach, policy &

dissemination

Background

Numbers

• About 500 million hectares of sub-Saharan Africa’s agricultural land are moderately or severely degraded

• African farmers are able to apply only 10 percent of the nutrients that farmers in the rest of the world return to the soil

• soils in southwestern Kenya, for example, lose an estimated 100 kilograms of nitrogen per hectare each year

Nutrient depleted soils reason for poor crops & low productivity

Large scale land degradation due to soil erosion: How to address?

Impact

Foreseen Impact• Provide accurate & spatially explicit soil database for 42

African countries

• Contribute to the reversal of soil degradation in Africa

• Contribute to increased crop yields & improved livelihoods for approximately 1 to 2 million poor African households

• Prepare material and evidence to guide policy and action that enhances Africa’s soil & crop productivity

• Contribute to the development of African institutions capacity to be able to map, disseminate and use soils information to plan natural resource management in their countries & in the continent

Project Activities

AfSIS Objectives

Objective 1: Global efforts to fund raise & prepare the GlobalSoilMap.net & collecting soil pedology legacy data for the African node (AfSIS)

Coordinated by ISRIC

Objective 2: Cyber Infrastructure & soils databaseCoordinated by CIESIN at Earth Institute

AfSIS ObjectivesObjective 4: • Implementing field management trials in 5 countries• Collecting & analyzing legacy experimental data

Coordinated by CIAT-TSBF

Objective 5: Capacity building, serving end users, defining use cases,

Coordinated by CIAT-TSBF

Objective 6: M & E plan and overall project management

Project Director –Dr. Pedro Sanchez

Soil Surveys

Objective 3

Markus Walsh, Tor Vagen, Keith Shepherd, Jerome Tondoh, Luseged

AfSIS Sentinel Sampling

• ~17.5 million km2 of continental SSA

• ~0.6 million km2 of Madagascar

• Spatially stratified random sampling approach consisting of 60 sites

• Each 100 km2 • 42 countries with 95% of

human population• ~9,600 new geo-referenced

soil profiles• 38,000 individual soil

samples

Which inputs are lacking?

Why inputs are not used?

Our aim: prevention, restoration & productivity

AfSIS Impact Target Zones

• Soil fertility recommendation trials installed in 5 countries marked in yellow

• Soil management recommendation framework developed from past experimental legacy data and from new management recommendation trials

Capacity building, user outreach & dissemination

Objective 5

Peter Okoth, Policy Economist, Extension, Market, other PIs, etc

Activities under Objective 5

• Capacity building

• Use Cases

• Impact pathways

• Policy formulation

• Partnerships

• Dissemination

• Monitoring & Evaluation

Training & Capacity building

• Training for capacity building in:– Soil Survey (numbers trained on the job)– NIR/MIR scanning, analysis & interpretations

(numbers trained on the job)– Management & recommendation trials

(numbers trained on the job)– ISFM and targeting recommendations

(numbers trained on the job)– Formal training ( numbers of graduate level

training at MSc & PhD)

Dissemination

Questions

• Dissemination: Which tools are currently available for this? How do we maximize out-scaling of

knowledge and data? Which are the incentives to ensure adoption

and sustenance of technology use once disseminated?

Who does what? How do they do it? Who pays for it?

Thank you!Ahsante sana!

Use cases

• Which uses of soil data and information can we think of?

• How do we capture the variety of potential users?

• Which tools are available to do this?• Which soil variables are most relevant?• Which decisions can be made from AfSIS

soil information • Which kind of decisions can be made?

Impact Pathways

• Partnerships: Which kind of partnerships do we need to

have for maximum impact? How do we structure the partnerships? How do we sustain the partnerships?
