Land Health Surveillance•Identify where land problems exist

•Quantify major risks to land health

•Target agroforestry interventions

•Evaluate the outcomes of interventions

Field Measurement

Page 2: Carbon Benefits Kds

Designed to provide;

biophysical baselines at

landscape level

(vegetation, soil condition)

a monitoring and evaluation

Sentinel Site Surveillance

Framework

a spatially stratified,

hierarchical, randomized

sampling framework

Sentinel site (100 km2)

16 Clusters (1 km2)

10 Plots (1000 m2)

4 Sub-Plots (100 m2)

LDSF sampling plot (1000 m2) with sub-plots (100 m2)

•Fast

•Repeatable

•Functional, interpretable

•Applicable everywhere

•Widely tested

•With local communities

Intervention Targeting

Priority afforestationintervention area (ha) based on woody cover ratings for each cluster (100 ha)Clusters in red have high priority due to high inherent degradation risk

Allometrics

•Biovolume to biomass to C

• Trees, shrubs, Species

• Belowground woody biomass

• Tapering coefficients; fractal branching

•Infrared spectroscopy for wood moisture and density

Improved wood density databases

Small chambers will be used to measure

the fluxes of N2O, CO2

and CH4 to generate default factors for

N2O and to estimate the soil respiration flux under different

land uses

Over the course of four years farmers, extension services, planners, the private sector, policymakers and scientists will have freely available, web-enabled access to a globally integrated, evidence-based, and dynamic soil health information service that provides management, planning and policy-relevant soil information for the non-desert portions of Sub-Saharan Africa.

A Globally Integrated African Soil Information Service
