Overview

Empowering drought adaptation decision-making

The Drought Impact Assessment Platform (d-iap) is an advanced, global, web-based tool designed to evaluate drought impacts on crop and water productivity, as well as irrigation water requirements, under present and future climate scenarios. Through the integration of diverse methodologies and tools, including the AquaCrop model and comprehensive global and regional databases, d-iap delivers pertinent insights into drought impacts for the main cultivable areas worldwide at a 0.1° x 0.1° (9 x 9 km approx.) resolution for both rainfed and irrigated agricultural systems. Its intuitive user interface facilitates the exploration and retrieval of various indicators tailored to specific coordinates or regions. Under rainfed conditions, these indicators encompass probabilities of yield reduction at different levels (mild –lower than 30%-, moderate –30 to 70%-, and severe –greater than 70%) due to drought, associated income losses, and the net irrigation requirements needed to mitigate the effects of drought.

Under irrigated conditions, the platform displays crop-specific net irrigation requirements and associated crop water productivity. Additionally, it provides the probability of meeting crop water needs with a specific irrigation amount. d-iap performs its assessments across up to 16 different crops, including multiple growing seasons within a year. These impacts can be evaluated for present climate conditions and future climate projections (mid-century and end-century) under three Shared Socioeconomic Pathways (SSPs, as defined in the IPCC Sixth Assessment Report) scenarios (SSP1-2.6, SSP3-7.0, SSP5-8.5). To streamline data management, d-iap provides different download formats for the platform outputs across various scales.
