1. Anticipating Impacts of AWM Interventions
Specific objectives
Activities
Status
1. Understand effect on CWP
Estimate CWP of Vertisols under current and alternative AWM scenarios
Model setting for major crops completed
Vertisol areas suitable for different AWM alternatives identified and mapped
Data on crop yield under different management still missing
Estimate CWP of other soils under selected AWM scenarios
Assessment of current AWM at different landscape positions in the selected catchments completed
Model setting for CWP under way by MSc students
Spatial distribution of crops on the landscapes ready for one site
Identify determinants of CWP
Data analysis under way to identify determinant factors of CWP based on the above at the landscape level
2. Quantify soil erosion as an indicator of land degradation
Measure sediment and nutrient loss at selected landscapes
Sediment sampling and laboratory analysis completed
Data cleaning and analysis underway
Objectives
1. Anticipate on-site Impacts

2. Anticipating Impacts of AWM Interventions
Relate nutrient loss to yield reduction or replacement cost at landscape level
Crop response functions for selected crops to and P
Established at landscapes level
Further analysis is underway
1. Understand effect on hydrology and water availability
Estimate differential CWR under the AWM scenarios
Estimate the impact on flow at sub catchment levels
Follows from above
2. Understand effect on water quality
Measure sediment and nutrient load
Sediment and nutrient concentration measured at sub-catchment level
1. Support and supervise graduate students from partner institutions
Provide research topics, financial support and guidance
6 students finalizing their thesis on two thematic areas:
CWP
Sediment and nutrient loss
2. Anticipate the off-site impacts
3. Contribute to capacity building
