Sticks and carrots: managing groundwater overabstraction in La Mancha, Spain por Closas, Alvar, Molle, Francois, Hernández Mora, N.

“…This paper presents a historical analysis of the different policy tools used to manage and regulate groundwater abstraction in the Western Mancha aquifer. Without much initial regulation and control, groundwater resources and aquifer levels decreased dramatically, threatening agriculture and also highly valuable groundwater-dependent wetland ecosystems. …”

Analysis of flow and baseflow trends in the Usangu Catchment, Tanzania por Shu, Yunqiao, Villholth, Karen G.

“…These phenomena may be partially explained by climate factors (including rainfall and potential evapotranspiration (ET)) as well as human activities (e.g. deforestation, irrigation, and groundwater abstraction) taking place in the lower as well as upper parts of the catchment.…”

Global environmental flow information for the sustainable development goals por Sood, Aditya, Smakhtin, Vladimir U., Eriyagama, Nishadi, Villholth, Karen G., Liyanage, Nirosha, Wada, Y., Ebrahim, Girma Yimer, Dickens, Chris

“…Additionally, EF have been separated into surface water and groundwater components, which also helps in developing sustainable groundwater abstraction (SGWA) limits. An online tool has been developed to calculate EF and SGWA in any area of interest.…”

Model-based estimation of land subsidence in Kathmandu Valley, Nepal por Shrestha, P.K., Shakya, N.M., Pandey, Vishnu Prasad, Birkinshaw, S.J., Shrestha, S.

“…Subsidence is predicted to occur as a result of deep aquifer compaction due to excessive GW abstraction. The north and north-east areas at the periphery of the GW basin are hotspots for this subsidence. …”

Groundwater governance: addressing core concepts and challenges por Closas, Alvar, Villholth, Karen G.

“…Existing recommendations focus on improved legal frameworks, monitoring and control of access and abstraction through permits or formal rights. In addition, decentralized water management, enforcement of regulations, and supply-side technological solutions are seen as cornerstone components of good groundwater governance systems. …”

Impact of land use changes and management practices on groundwater resources in Kolar district, Southern India por Garg, K. K., Anantha, K. H., Nune, R., Akuraju, V. R., Singh, P., Gumma, Murali K., Dixit, S., Ragab, R.

“…The irrigation demand of the district increased from 57 mm (1972) to 140 mm (2011) which resulted in increased groundwater abstraction by 145 %. The expansion of the irrigated area is the major contributing factor for widening the demand-supply gap (62 %) of the freshwater availability. …”

Small private irrigation: enhancing benefits and managing trade-offs por Giordano, Meredith A., Fraiture, Charlotte de

“…Women and resource poor farmers face challenges accessing affordable technologies; market inefficiencies and policy frameworks negatively affect farmer decision-making and technology access; and the unregulated spread of private irrigation may lead to over-abstraction, pollution, and conflicts. In this paper we argue that carefully designed intervention strategies and policy engagement are needed for two reasons. …”

Perceptions of groundwater degradation and mitigation responses in the Haouaria region in Tunisia por Mekki, I., Ghazouani, Wafa, Closas, Alvar, Molle, Francois

“…The plain of Haouaria, in north-eastern Tunisia, has witnessed an important development of groundwater abstraction, fueled by the multiplication of wells tapping the underlying shallow and deep aquifers. …”

Sketching in VR for landscape architects por Wahlström, Johanna

“…Future investigation could explore: having multiple users in a VR setting at the same time, exploring the possibilities with different levels of abstraction, the different types of intuition, to use a checklist to get started but not to get creative, and to generally expand the academic discourse as technology advances.…”

Groundwater-Extracting Rice Production in the Rejoso Watershed (Indonesia) Reducing Urban Water Availability: Characterisation and Intervention Priorities por Khasanah, N.M., Tanika, L., Pratama, L.D.Y., Leimona, B., Prasetiyo, E., Marulani, F., Hendriatna, A., Zulkarnain, Muhammad Thoha, Toulier, A., Noordwijk, M. van

“…Analysis of the water balance suggested that the decline by about 30% in spring discharge in the past decades is attributed for 47 and 53%, respectively, to upland degradation and lowland groundwater abstraction. Consequently, current spring restoration efforts support upland agroforestry development while aiming to reduce lowland groundwater wasting. …”

Understanding water governance in the Central Rift Valley of Ethiopia: governance framework, coherence and practices por Jibat, E., Senbeta, F., Zeleke, T., Hagos, Fitsum

“…Lack of coherence in water policy implementation, absence of clear roles and responsibilities of stakeholders, absence of transparency and accountability in irrigation water service delivery, and lack of meaningful participation of key actors in water governance decision-making were observed. As a result, over-abstraction, deterioration of buffer zone areas, and chemical erosion from surrounding farming are attributed to the reduction in water volume and quality in the CRV. …”
