Governing agricultural drought: Monitoring using the vegetation condition index

Ethiopian Journal of Environmental Studies and Management, 2016
This paper investigates the spatial and temporal aspect of seasonal agricultural drought in Ethiopia during the cropping season using Vegetation Condition Index. SPOT-VGT S10 NDVI time-series for the period 1998 to 2013 was employed. Five hundred and sixty-seven dekadal images were administered in order to produce the multi-temporal agricultural ...

How cold is too cold? A theoretical analysis of the optimal trigger for index insurance for frost damage to crops

American Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.

Optimizing subsoiling depth to enhance soil water storage and annual crop water productivity in wheat-maize cropping system

Agricultural Water Management
Subsoiling effectively enhances crop water productivity (CWP) by optimizing soil structure. Nevertheless, the effects of different subsoiling depths on cross-seasonal soil water utilization and CWP remain unclear.

Drought Propagation Patterns under Naturalized Condition Using Daily Hydrometeorological Data

Advances in Meteorology, 2018
Drought propagation pattern forms a basis for establishing drought monitoring and early warning. Due to its regional disparity, it is necessary and significant to investigate the pattern of drought propagation in a specific region.

MATHEMATICAL MODELING OF DROUGHT RESILIENCE IN AGRICULTURE

Natural Resource Modeling, 2012
Abstract.  Ensuring drought resilience for farmers is an important policy concern. Yet, a quantitative treatment of the concept of drought resilience has been lacking in the literature. This paper designs a mathematical model of drought resilience to assess farmers’ survival strategies when faced with the prospect of repeated droughts.

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market
