Greening cities to ensure biosphere functional integrity: Insights from Rotterdam and Lagos

The Earth Commission has proposed that 20-25% of every square kilometre of managed lands, including in cities, be reserved for nature to ensure its local functioning and human wellbeing -biosphere functional integrity boundary (BFI). This research adopted a multi-method justice-o...

The WoKaS-Iso database: workflow for a global compilation of oxygen-18 and deuterium records in karst springs and cave drip water for enhanced understanding of karst systems

For analysing karst hydrogeological systems, observations of karst springs and cave drips are considered indispensable. In addition to hydrometric observations, knowing the oxygen and hydrogen stable isotope ratios has improved the understanding of vadose zone and aquifer dynamic...

Retrieval of Optically Active and Inactive Water Quality Parameters Using Remote Sensing and Machine Learning: Evidence from Water Hyacinth-Infested Lake Tana, Ethiopia

Monitoring water quality is critical for protecting freshwater ecosystems and supporting sustainable water resource management. Lake Tana, Ethiopia’s largest freshwater lake, faces increasing agricultural and urban pressures, while conventional monitoring remains costly and spati...

Global hyper-resolution modeling of historical and future groundwater dynamics

Abstract. The sustainable management of global groundwater resources is a key societal challenge and is central to the Sustainable Development Goals. The localized dynamics of groundwater abstraction, topography, and surface-water interactions, as well as the sensitivity of groun...

Vulnerability of the freshwater lens to groundwater abstraction and climate change on Muli Island, Maldives

Abstract In small coral islands, groundwater is often the primary source of water supply. However, their aquifers are less resilient to climate and environmental changes because groundwater storage is limited by a small island area, flat terrain, and a thin freshwater lens. In th...

How Good Is Your Forecast? The Importance of User‐Centred, Decision‐Relevant Evaluation of Forecasts and Climate Services

ABSTRACT Forecasts and climate services, spanning weather and climate timescales, play a vital role in supporting short‐ and long‐term decision‐making across a wide range of climate‐sensitive sectors. Understanding their skill is crucial to ensuring that the information provided...

The world is being fed at the expense of nature: A remote sensing based global assessment from 2000 to 2019

Understanding agricultural productivity dynamics is essential for evaluating the global capacity to achieve food security while safeguarding nature. This requires tracking food production relative to natural resource use. The Comprehensive Assessment of Water Management in Agricu...

Revisiting the wetland wise use concept after 50 years – ‘flogging a dead horse’ or ‘‘dusting the golden vase’

Abstract Introduced in the text of the Ramsar Convention on Wetlands over five decades ago, the wetland wise use concept was a unique recognition of human-nature connectedness and a genuine precursor to sustainable development. Yet, the use of the term has been inconsistent withi...
