مستخلص: The acceleration of transboundary water cooperation is essential to support water security and ensure mutual benefits of sustainable development. The way existing Sustainable Development Goal (SDG) monitoring data is used to raise its importance further up political agendas and inform future reporting rounds is therefore crucial to acceleration. Using data extracted from national country reports of SDG indicator 6.5.2 on transboundary water cooperation, we showcase the level of cooperation, as reported, per aquifer to compliment the national approach currently followed by the official SDG framework. Our analysis uncovers a variety of insights and challenges to transboundary aquifer (TBA) cooperation that otherwise might be difficult to visualize through official national reports. Reported aquifer cooperation is often not harmonized across international borders. A lack of groundwater data and information is a major contributing factor to uncoordinated reporting, highlighting the importance of a sound scientific baseline. However, harmonization issues are also interlinked to a nationalfocused reporting process where Member States have the right to disagree over the status of their joint cooperation. These results can assist in improving future indicator coverage, both as an awareness raising tool for co-custodian agencies and by countries through direct interventions and coordination with neighbours.

الملخص (بالإنجليزية): As the reliance on transboundary groundwater is increasing globally, it is important to understand and address the specific issues raised by the assessment and management of transboundary aquifers (TBAs). Building on 20 years of TBA experience and through a three-pillar framework (assessment, cooperation-collaboration, shared management), the key elements to addressing TBA issues are described, including a multidisciplinary approach, identification of hotspot zones, local vs border-wide approaches, appropriate funding models, and an increased recognition of the role and value of each TBA.

Abstract (Spanish): Resumen: Ante la creciente utilización de las aguas subterráneas transfronterizas en todo el mundo, es importante comprender y abordar los problemas específicos que plantean la evaluación y la gestión de los acuíferos transfronterizos (TBAs). Sobre la base de 20 años de experiencia en materia de TBA y a través de un marco de tres principios (evaluación, cooperación-colaboración, gestión compartida), se describen los elementos clave para abordar los problemas de los TBA, incluyendo un enfoque multidisciplinar, la identificación de zonas críticas, enfoques locales frente a los que abarcan toda la región, modelos de financiación adecuados y un mayor reconocimiento del rol y el valor de cada TBA.

مستخلص: Integrated Water Resources Management (IWRM) is vital to the future of Malawi and motivates this study's provision of the first stable isotope baseline characterization of the Shire River Basin (SRB). The SRB drains much of Southern Malawi and receives the sole outflow of Lake Malawi whose catchment extends over much of Central and Northern Malawi (and Tanzania and Mozambique). Stable isotope (283) and hydrochemical (150) samples were collected in 2017–2018 and analysed at Malawi's recently commissioned National Isotopes Laboratory. Distinct surface water dry-season isotope enrichment and wet-season depletion are shown with minor retention of enriched signatures ascribed to Lake Malawi influences. Isotopic signatures corroborate that wet-season river flows mostly arise from local precipitation, with dry-season flows supported by increased groundwater contributions. Groundwater signatures follow a local meteoric water line of limited spread suggesting recharge by local precipitation predominantly during the peak months of the wet-season. Relatively few dry-season groundwater samples displayed evaporative enrichment, although isotopic seasonality was more pronounced in the lowlands compared to uplands ascribed to amplified climatic effects. These signatures serve as isotopic diagnostic tools that valuably informed a basin conceptual model build and, going forward, may inform key identified Malawian IWRM concerns. The isotopic baseline establishes a benchmark against which future influences from land use, climate change and water mixing often inherent to IWRM schemes may be forensically assessed. It thereby enables both source-water protection and achievement of Sustainable Development Goal 6. [ABSTRACT FROM AUTHOR]
