This paper articulates the complexities of adaptively managing Delaware River water resources to meet shifting priorities of drinking water supply, drought mitigation and flood mitigation, as well as conflicting stakeholder interests. In particular, the paper examines the short-term and long-term programs that comprise the Delaware River Basin Commission's (DRBC) and the 1954 US Supreme Court Decree parties' successful adaptive management approach that seeks to balance the growing list of demands for water resources management, including drinking water supply, drought management, flood control and cold water fisheries protection. Review of the DRBC's adaptive governance approach reveals the critical complexities of designing experimental, yet science-driven management approaches and effectively engaging various sets of stakeholders in the associated decision-making processes.

Abstract. Karst develops through the dissolution of carbonate rock and is a major source of groundwater contributing up to half of the total drinking water supply in some European countries. Previous approaches to model future water availability in Europe are either too-small scale or do not incorporate karst processes, i.e. preferential flow paths. This study presents the first simulations of groundwater recharge in all karst regions in Europe with a parsimonious karst hydrology model. A novel parameter confinement strategy combines a priori information with recharge-related observations (actual evapotranspiration and soil moisture) at locations across Europe while explicitly identifying uncertainty in the model parameters. Europe's karst regions are divided into four typical karst landscapes (humid, mountain, Mediterranean and desert) by cluster analysis and recharge is simulated from 2002 to 2012 for each karst landscape. Mean annual recharge ranges from negligible in deserts to > 1 m a−1 in humid regions. The majority of recharge rates range from 20 to 50% of precipitation and are sensitive to subannual climate variability. Simulation results are consistent with independent observations of mean annual recharge and significantly better than other global hydrology models that do not consider karst processes (PCR-GLOBWB, WaterGAP). Global hydrology models systematically under-estimate karst recharge implying that they over-estimate actual evapotranspiration and surface runoff. Karst water budgets and thus information to support management decisions regarding drinking water supply and flood risk are significantly improved by our model.

This Special Issue addresses topics on the water–energy–food (WEF) nexus along with other water-related topics, such as water resources, irrigation and drinking water supply systems, hydraulics and pollution. Several threats jeopardize freshwater availability and quality, energy and food availability. Integrated management approaches are absolutely necessary for pursuing sustainability. This Special Issue addresses various subjects and includes 29 peer-reviewed papers that have been grouped into the following categories: the WEF nexus, water resources and irrigation systems, drinking water supply systems, hydraulics and pollution. Some of them were selected from the Third Efficient Water Systems (EWaS) International Conference, entitled “Insights on the Water–Energy–Food Nexus,” after a thorough content update. Summaries of the papers are briefly presented in this Editorial.

Abstract. Rajasthan, the largest State in India, has one of the most critical water statuses. Rajasthan, with more than 10.4 % of the country’s geographical area, supports more than 5.5 % of the human population and 18.70 % of the livestock, but only has 1.16 % of the total surface water available in the country. More than 60 % of the state is a part of the Great Thar Desert, and of the total 142 desert blocks in the country, 85 blocks are in the state of Rajasthan. The per capita annual water availability in the state is about 780 m3, compared with the minimum requirement of 1000 m3. It is feared that the availability would fall below 450 m3 by the year 2050. Thus, increasing population coupled with erratic rainfall further aggravates the water crisis. It is possible to harvest and augment water resources through the construction of small water harvesting structures called johads and the implementation of local water governance. This has been amply demonstrated by the successful experience of local communities in Alwar District in Rajasthan. Since 1985, 8600 johads have been built in 1086 villages. This has resulted in the rise in water levels in the shallow aquifer, increase in the area under single and double crops, increase in forest cover and drinking water supply security. The water collected in a johad during the monsoon penetrates into the sub-soil. This recharges the groundwater and improves the soil moisture in vast areas. The water in the johad can be used directly for irrigation, drinking water by animals, and other domestic purposes. The other advantage of this structure is that it checks soil erosion, mitigates floods, and ensures water availability in wells or boreholes used for drinking water supply, even for several successive drought years. Also, during the dry season when the water gradually recedes in the johad, the land inside the johad itself becomes available for cultivation.

The contamination of the world’s water supply due to various contaminants has caused the clean water supply to shrink around the globe. The problem is not only an issue with developing nations; in fact, many developed countries are facing the same turmoil. With the globalization, industrialization and weak enforcement of environmental regulations, waste water is discharged into clean water resources whereby contaminating the water. Out of the long list of contaminants many heavy metals find their way into the clean drinking water supply. The heavy metals arsenic (As), lead (Pb), and mercury (Hg) as well as many others are also discharged into water resources. There are numerous methods for removal of these heavy metals from water including filtration, chemical precipitation, ion exchange, adsorption, electro deposition as well as others but most are expensive and or not completely satisfactory. Arsenic and its compounds are often used as pesticides, herbicides, insecticides and various alloys and often find their way into the drinking water supply through various industrial sources. A cost-effective remediation of arsenic in water using readily available material is urgently needed. An ashed waste material consisting primarily of Azadirachta indica (Neem leaves) and Mangifera indica (Mango leaves) has been found effective in removing both arsenic (III) and (V) from water. The utilization of this ashed material achieves the concept of using waste material from one source, used by another and therefore benefiting both. The adsorbent is very effective at pH =7 and ion exchange appears to be the major adsorption mechanisms for binding the metal ions to the plant ash material. The material shows sufficient operation capacity to indicate the possibility of its use in remote rural areas as well as in an urban water treatment facility.

The Kota Makassar water utility serving (<em>Perusahaan Daerah Air Minum</em> - PDAM) faces a significant problem in managing water resources for their drinking water supply. The problems comprise raw water supply, the vulnerability of water quality, infrastructures, costs, and climate change uncertainty. The availability of clean water is one of the problems in the field of national defense. Because water is the main source of life in all sectors, be it agriculture or livestock. This study is aimed at assisting officials in making an adaptive and resilient decision. It involves inter-and cross-disciplinary studies within Robust Decision-Making (RDM) in water resources management planning for drinking water supply and disaster mitigation in Makassar. This research applies a qualitative approach in data analysis; reviewing strategies used by the utility management to anticipate all uncertainty, long-term strategies feasibility from simulation models, analyzing potential vulnerability scenarios, and the trade-off for an adaptive and robust decision in water resources management planning for drinking water supply in Makassar through RDM. The novelty lies in the raw water management policy that is more adaptive toward potential vulnerability and presents a variety of raw water supply alternatives in the long term. Reviews against the document of drinking water Master Plan found that the absence of harmony along with a high level of anticipation towards the threat of climate change along with their impact, as well as the threat of the raw water supply limitations due to the exogenous problems beyond the reach of human beings capacity, will result in global and long-term impact.
