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

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
