Subject Area
Globally, groundwater use is intensifying to meet demands for irrigation, urban supply, industrialization, and, in some instances, electrical power generation. In response to hydroclimatic variability, surface water is being substituted with groundwater, which must be viewed as a strategic resource for climate adaptation. In this sense, the supply of electricity for pumping is an adaptation policy tool. Additionally, planning for climate-change mitigation must consider CO2 emissions resulting from pumping. This paper examines the influence of electricity supply and pricing on groundwater irrigation and resulting emissions, with specific reference to Mexico—a climate–water–energy 'perfect storm'. Night-time power supply at tariffs below the already-subsidized rates for agricultural groundwater use has caused Mexican farmers to increase pumping, reversing important water and electricity conservation gains achieved. Indiscriminate groundwater pumping, including for virtual water exports of agricultural produce, threatens the long-term sustainability of aquifers, non-agricultural water uses, and stream–aquifer interactions that sustain riparian ecosystems. Emissions resulting from agricultural groundwater pumping in Mexico are estimated to be 3.6% of total national emissions and are equivalent to emissions from transporting the same agricultural produce to market. The paper concludes with an assessment of energy, water, and climate trends coupled with policy futures to address these challenges.

well my name's Christopher Scott like to tell you a little bit about my research on ground water energy and climate change and I'd be focused my work on Mexico for the paper that used in the environment such
letters I've also done some work on the
topic in India and I
have spending work in South America in
their regions this important challenge because groundwater is a resource of increasing strategic importance humans
rely on it for a range of purposes
ecosystems are indirectly through stream ground at for interactions are dependent in some cases on groundwater
and we're using ground water is being depleted are at unprecedented rates the particular focus of the paper is on how the electricity supply electricity policy pricing rationing and supply options can influence groundward of Mexico is a perfect storm in terms of climate and energy in waters nexus partly because Mexico has undertaken some innovative approaches to address the
challenge of groundwater position on the paper
and other parts of the research that I
invite you to look at I'm pleased to check what was set up for slash

groundwaters land and thank you very much so it shouldn't
