“…For example, PVACD draws water from an aquifer that is recharged by regional groundwater flow, which is recharged by precipitation in the Sacramento Mountains and flows toward the Pecos River (Rawling and Newton, 2016). While it is beneficial to have a recharge source (which will be reduced by climate change, as discussed in Chapter 3), there are drawbacks in this case.…”

All water that we use in New Mexico originates as rain or snow falling onto the landscape, which either goes to groundwater or surface water or returns to the atmosphere. Of the precipitation that falls on the state, 1.6% runs off into streams and rivers, and 1.8% infiltrates into the ground, recharging subsurface aquifers. Much larger proportions are transpired by plants (78.9%) or evaporated (17.7%). The impact of climate change on all of these pathways will affect our state's water budget. Notably, because of the larger percentages of water lost to evaporation or transpiration, even very small changes in these factors will result in large changes to runoff and recharge. As mentioned in Chapter 2, the climate will continue to warm over the next 50 years, likely without an increase in precipitation, leading to greater statewide aridity. Hydrological modeling indicates declines in both runoff and recharge going forward, amounting to 3% to 5% per decade for both quantities. Historical trends in runoff indicate significant year-to-year variability, as do trends in soil moisture and recharge. But all are generally decreasing, consistent with the results of climate models that project a drying climate. Combining the historical trends with modeling of future changes, significant decreases in runoff and recharge seem very likely. TERRESTRIAL ECOSYSTEMSClimate is a fundamental driver of ongoing and future vegetation changes in New Mexico. Future changes in vegetation will affect the distribution and abundance of water resources in New Mexico. Major shifts in climate and vegetation across New Mexico's landscapes have occurred in the past, but the scale and rate of recent and projected climate change is probably unprecedented during the past 11,000 years. Recent warming, along with frequent and persistent droughts, have amplified the severity of vegetation disturbance processes like fire, physiological drought stress, and insect outbreaks, driving substantial changes in New Mexico vegetation since the year 2000. Ongoing and projected vegetation changes include growth declines, reduced canopy and ground cover, massive tree mortality episodes, and species changes in dominant vegetation-foreshadowing more severe changes to come if current warming trends continue as projected. Such major alterations of New Mexico vegetation likely will also have substantial ecohydrological feedbacks with New Mexico water resources. Since water-related environmental stresses occur in parallel with water supply shortages for people, such climate-change-driven water stress could lead to increasing conflict between managing declining water available for human use (e.g., irrigation) and retaining "wild" water for the maintenance of historical ecosystems.

“…Furthermore, even the mechanisms of subterranean abiotic processes are still not wholly known. It is worth noting that the groundwater pH is essentially significant for the local water environment and has attracted a wide attention [50][51][52][53][54][55][56][57][58][59][60]. Attaining a reliable quantification for the contributions of soil CO2 uptake to the groundwater environment remains one major challenge and hence should be a research priority.…”

Recent studies of soil carbon cycle in arid and semi-arid ecosystems demonstrated that there exists an abiotic CO 2 absorption by saline-alkali soils (A a ) at desert ecosystems and suggested potential contributions of CO 2 dissolution beneath deserts to the terrestrial ecosystems carbon balance. However, the overall importance of such soil CO 2 uptake is still undetermined and its implications to the groundwater environment remain unaddressed. In this manuscript, a simple method is proposed for the direct computation of A a from the total soil CO 2 flux (F a ) as well as for the evaluation of A a importance to F a . An artificial soil-groundwater system was employed to investigate the implications to groundwater environment and it was found that soil CO 2 uptake in deserts can contribute a possible influence on the evolution of the groundwater environment, providing that the absorbed CO 2 largely remained in the soil-groundwater system.

In New Mexico in the arid southwestern United States, groundwater recharge is crucial to sustain groundwater (GW), which is vitally important to life, agriculture, industry, and ecosystems. To better understand the changes in recharge statewide, we explored the changes in groundwater recharge (RE), precipitation (P), surface water inflow (SW in ), outflow (SW out ), diversions (SW div ), returns (SW ret ), and surface water and GW evapotranspiration (SW E and GW ET ) in five New Mexico counties: Taos, Torrance, Do ña Ana, Eddy, and Lea during 1975-2015. The results show that the change-point of RE was in the 1990s, leading to contrasting tendencies in RE before and after the change-point with a decreasing rate during the latter one. There was a significant positive relationship between RE and P for Taos. The highest contribution rate (CR) to RE was SW out for Taos, whereas GW ET ranked as the top CR for the other counties. Furthermore, the annual CR of GW ET to RE increased significantly in all counties except Lea. The above results reveal that P and surface water flows played the dominant role in impacting RE in northern New Mexico where surface water is the primary local water resources, whereas GW ET had the highest and increasingly continuous influence in central and southern New Mexico where the surface water is much less than that in northern New Mexico. This study shows that water budgets are important to identify differences in regional hydrological regimes that affect planning to maintain RE to groundwater.
