Groundwater is a critical water supply around the world and is increasingly under threat from pumping that exceeds natural replenishment. California is taking on this challenge with the Sustainable Groundwater Management Act (SGMA) of 2014, which seeks to reliably manage groundwater to meet current and future water needs for the economy, communities and environment. Successful implementation of SGMA depends on the ability of local agencies to work with stakeholders to develop plans and implement projects that reduce groundwater use, increase recharge and efficiently allocate pumping. With more than 250 local agencies undertaking actions to address groundwater overdraft, California serves as a unique laboratory for testing new ways to achieve groundwater management. At the same time, economic tools are increasingly being utilized to secure or deliver water to the environment. For the past several years, The Nature Conservancy has been testing ways that economic tools can help achieve groundwater sustainability. This paper presents case studies that illustrate how two forms of Payment for Ecosystem Services (PES) — a groundwater market and a multi-benefit recharge incentive program — are being used in California to achieve groundwater sustainability to simultaneously meet the water needs of people and nature.

<p>Sustainability Indices can be useful to quantify objective groundwater management strategy outcomes, particularly across regional scales and when local groundwater budget data is not readily available. Previous studies have used performance indicators to evaluate surface water systems, and their application to groundwater is expanding to address water availability concerns. Here, a groundwater sustainability index (GSI) is computed across coastal aquifer systems in Portugal and California using reliability (REL), resilience (RES), and vulnerability (VUL) performance indicators. Aquifers in these Mediterranean climate zones are susceptible to inter-annual and seasonal water storage fluctuations linked to climate forcings and drought. Piezometric levels in the selected aquifers in Portugal (Leirosa-Monte Real and Campina de Faro) and California (Napa and Santa Barbara), spanning a period from 1989 to 2019, are analyzed using a point-wise approach to provide an index-per-piezometer. The computation exposes that the resilience indicator is heavily influential in setting an aquifer system's overall sustainability classification. However, the most significant output from the GSI is a clear indication of how well (or poor) a specific aquifer can withstand drought conditions that occur in both California and Portugal throughout the 30-year span of this study. Lastly, comparing indices with different priorities (performance indicators), such as sustainability and exploitive use (including the Water Framework Directive’s River Basin Management Plan’s Water Exploitation Index (WEI+)) can help identify aquifer systems that may need an immediate policy, conservation, or mitigation interventions, and others that may be self-sustaining for a longer period of time.

Sustainable Extraction

Sustainable groundwater management is an important practice of water resources engineering, especially, in case of deserts and oases where there is no source of surface water and precipitation rarely occurs. The importance increases when the only source of groundwater is a nonrenewable aquifer. This is the case of new reclaimed areas in Farafra Oasis, Western Desert of Egypt. The only source of irrigation water is groundwater extracted from the nonrenewable Nubian Sandstone Aquifer (NSA). There is a great agricultural development in Farafra Oasis as a part of the 1.5 million feddan mega project. Agricultural development, for new areas, is a must for Egypt to fulfil the increasing food demand accompanied with the increasing population growth rate. However, this development has to consider the sustainability of groundwater usage along with the social, economic, and national security aspects. Groundwater extraction rate from NSA has increased. As it is a nonrenewable aquifer, there is no groundwater recharge. Consequently, the groundwater potentiometric level (GPL) decreases with time. The traditional sustainability concept of safe yield or discharge equals recharge is not applicable on such cases. The Ministry of Water Resources and Irrigation (MWRI) of Egypt set the groundwater sustainability criteria for groundwater-dependent new reclaimed areas in Farafra Oasis, Western Desert of Egypt. Both duration and economic lifting depth, have been considered. This paper presents groundwater sustainability assessment for extraction rates, Qwell = -1000, -2000, -3000, -4000, and -5000 m3 /d, to obtain the most beneficial sustainable extraction rate according to the MWRI sustainability criteria. A new groundwater-dependent reclaimed area of 10,000 feddan in Sahl Baraka, Farafra oasis, was taken as a case study area. GIS functions were used to obtain the values of unknown data and develop the initial groundwater potentiometric map. MODFLOW was used to construct a numerical model for groundwater extraction rate simulation for the case study area. This model was calibrated and used to obtain the depression cone drawdown (DCD) associated with different extraction rates. All NSA regional drawdown rates at Farafra oasis were considered. Benefit –Deficit analysis for duration and economic lifting depth criteria are presented and show that the extraction rate of Qwell = -3000 m3 /d is the most beneficial sustainable extraction rate according to the MWRI adopted sustainability criteria

Basin Scale

A system dynamics approach to groundwater modeling suitable for groundwater management planning is presented for a basin-scale system. System dynamics techniques were used to develop a general model for estimating changes in net annual groundwater storage. This model framework was applied to two inland groundwater basins in California and tested against groundwater depletion data developed by the United States Geological Survey. Changes in net groundwater storage developed from these models were compared to values from numerical models provided by the United States Geological Survey. The basin-specific models were able to replicate changes in net annual groundwater storage volumes for 1-year and 5-year periods at a level suitable for planning, with R2 values ranging from 0.88 to 0.93. At the 10-year prediction period, R2 values ranged from 0.83 to 0.91. The results of this research illustrate that a system dynamics model using observed relationships between components may be capable of predicting behavior for the purposes of groundwater management planning.

As risks evolve and diversify, approaches to conducting business require a targeted focus on risk management, particularly in agriculture. This new 3-page document explores risk in agriculture, the need to understand risk, formation of strategies to manage risk, and government programs that exist to help growers and producers manage risk.

Pastoral Farming

The growth in horticultural and some industrial development in selected areas of Northland has led to a need for more specific and careful planning and control of limited resources in a number of major catchments. The potential irrigation demands for horhculture comprise over 60% of Northland's potential water requirements. By contrast, farm water supply needs are only 11% of these needs. Because of their importance to the Northland economy, and in the legislation these needs are given a high priority in water resource management planning. Land uses, including pastoral farming, require careful operation to reduce diffuse sources of pollution.
