Abstract Human activity increases the atmospheric water vapour content in an indirect way through climate feedbacks. We conclude here that human activity also has a direct influence on the water vapour concentration through irrigation. In idealised simulations we estimate a global mean radiative forcing in the range of 0.03 to +0.1 Wm–2 due to the increase in water vapour from irrigation. However, because the water cycle is embodied in the climate system, irrigation has a more complex influence… Expand
Irrigation as an historical climate forcing
Abstract Irrigation is the single largest anthropogenic water use, a modification of the land surface that significantly affects surface energy budgets, the water cycle, and climate. Irrigation,Expand
Impact of Irrigation on Climate
Irrigation is one of the most important land management techniques used to grow crops in dry areas and increase food production. The use of agricultural irrigation has grown rapidly over the past 200Expand
Ocean–atmosphere interactions modulate irrigation's climate impacts
Abstract. Numerous studies have focused on the local and regional climate effects of irrigated agriculture and other land cover and land use change (LCLUC) phenomena, but there are few studies on theExpand
A modelling exploration of the sensitivity of the India’s climate to irrigation
The Indian subcontinent is one of the most highly irrigated regions of the world where water use has intensified since the second half of the twentieth century. This agricultural intensification hasExpand
Present‐day irrigation mitigates heat extremes
Irrigation is an essential practice for sustaining global food production and many regional economies. Emerging scientific evidence indicates that irrigation substantially affects mean climateExpand
Effects of Great Plains Irrigation on Regional Climate

Irrigation is crucial for sustaining agriculture in certain regions; however, there are effects on the local climate. Previous studies discussed that the irrigation signal might depend on theExpand
Seasonal effects of irrigation on land–atmosphere latent heat, sensible heat, and carbon fluxes in semiarid basin
Abstract. Irrigation, which constitutes ∼ 70 % of the total amount of freshwater consumed by the human population, is significantly impacting land–atmosphere fluxes. In this study, using the improvedExpand
Impacts of irrigation and anthropogenic aerosols on the water balance, heat fluxes, and surface temperature in a river basin
[1] Changes in both land cover and the atmosphere have impacted the heat fluxes of south Asia in ways that may have altered the timing and magnitude of the monsoon. Century-long budgets of water andExpand
