TLDR
The Variable Infiltration Capacity model, a novel blending procedure incorporating the spatial correlation structure of CCD-estimates to assign interpolation weights, is presented and it is shown that CHIRPS can support effective hydrologic forecasts and trend analyses in southeastern Ethiopia.Abstract:
The Climate Hazards group Infrared Precipitation with Stations (CHIRPS) dataset builds on previous approaches to ‘smart’ interpolation techniques and high resolution, long period of record precipitation estimates based on infrared Cold Cloud Duration (CCD) observations. The algorithm i) is built around a 0.05° climatology that incorporates satellite information to represent sparsely gauged locations, ii) incorporates daily, pentadal, and monthly 1981-present 0.05° CCD-based precipitation estimates, iii) blends station data to produce a preliminary information product with a latency of about 2 days and a final product with an average latency of about 3 weeks, and iv) uses a novel blending procedure incorporating the spatial correlation structure of CCD-estimates to assign interpolation weights. We present the CHIRPS algorithm, global and regional validation results, and show how CHIRPS can be used to quantify the hydrologic impacts of decreasing precipitation and rising air temperatures in the Greater Horn of Africa. Using the Variable Infiltration Capacity model, we show that CHIRPS can support effective hydrologic forecasts and trend analyses in southeastern Ethiopia.read more

Conservation agriculture improves adaptive capacity of cropping systems to climate stress in Malawi
TL;DR: In this article, the statistical effect of conservation agriculture on cropping-system yields under historical climate conditions is estimated. But, the authors focus on how adaptation options affect yields of a single crop under different weather or climate conditions.

The role of active soil carbon in influencing the profitability of fertilizer use: empirical evidence from smallholder maize plots in Tanzania
TL;DR: Active soil carbon is found to be a strong predictor of maize yield response to nitrogen fertilizer, and important sources of variation in the returns to fertilizer investments across plots and smallholder farmers in the region are highlighted.
