What does this research mean for the field?

Adjusting rice planting dates by up to 21 days for double-cropping systems or 50-70 days for single-cropping systems can significantly reduce irrigation water demand and mitigate the adverse impacts of future climate change in Taiwan. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Implication

Randomized trial assesses planting date adjustments on irrigation water demand in Taiwan, suggesting strategic shifts could mitigate climate impacts.

Key Points

This study aims to evaluate how adjusting planting dates affects irrigation water demand under future climate change scenarios in Taiwan.
Utilized the FAO AquaCrop model calibrated with detailed canopy cover data (R² = 0.99 and 0.91) to estimate irrigation water demand for paddy rice.
Applied a shifting planting-date approach from 21 days earlier to 21 days later in seven-day increments across multiple climate scenarios.
Examined the impact of adjustments in planting dates on irrigation water demand for both double-cropping and single-cropping systems.
First cropping season requires higher irrigation water demand, reaching up to 180 mm, especially under SSP5–8.5 scenarios.
Optimal water savings of 80 mm and 150 mm are achievable through strategic planting date shifts in single-cropping systems, depending on region.
Future projections show a potential increase in irrigation water demand up to 40 mm along the western coastal plain.
