Irrigation Expansion Required to Mitigate Yield Losses Under Climate Change
收藏资源简介：
The "crop_production_summary.xlsx" gives the global and country-level aggregated crop production (e.g., wheat, maize, rice and barley) (unit: 10^12 kcal) during Baseline periods (1996-2005), 1.5°C and 3°C warming above pre-industrial levels (1850-1900) using three irrigation adaptation scenarios: (i) without irrigation adaptation, which means using the historical irrigation extent around 2000 (ii) with full irrigation adaptation, which means applying 100% irrigation over all croplands and (iii) with sustainable irrigation adaptation, which selectively applies irrigation where irrigation practices do not deplete freshwater stocks and impair aquatic ecosystems. The "irr_need_summary.xlsx" gives the global and country-level sustainable and unsustainable irrigation area (unit: million hectares) of each crop (e.g., wheat, maize, rice and barley) in 2000 and additional irrigation area needed to offset warming-induced crop yield losses under 1.5°C and 3°C warming above pre-industrial levels (1850-1900). The "irrigation needed" folder contains pixel-level additional irrigation area fraction for each crop needed to offset warming-induced crop yield losses under 1.5°C and 3°C warming above pre-industrial levels (1850-1900). The "yield change" folder contains pixel-level crop yield change for each crop under 1.5°C and 3°C warming above pre-industrial levels (1850-1900). The "irrigation_sustainable" folder contains pixel-level data on irrigation water sustainability during the Baseline periods (1996-2005) and under 1.5°C and 3°C warming scenarios compared to pre-industrial levels (1850-1900). In this dataset, pixels with values <1 indicate that sustainable irrigation can be applied, while values >=1 indicate that irrigation will be unsustainable.
