1. Introduction

Water, often described as the planet’s lifeblood, faces mounting stress from escalating demand, climate change, and pollution [1]. Once perceived as limitless, this invaluable resource is now understood to be finite and increasingly scarce. The distribution of water resources across the globe is uneven, with some areas enjoying water abundance and others wrestling with severe scarcity. Countries endowed with extensive river systems, such as Canada and Brazil, stand in stark contrast to arid and semi-arid regions such as the Middle East and North Africa, where chronic water shortages persist [2,3]. The pressure on water resources intensifies with rapid urbanization and population growth, as seen in countries such as India and China, leading to the overuse of groundwater and stress on surface water bodies [4,5]. The challenges are further compounded by climate change, which introduces greater unpredictability in water availability, evidenced by an increase in both droughts and floods [6]. With the world’s population on the rise and ever-progressing climate change, sustainable water resource management has become an urgent necessity [7].

Water resources, central to sustainable socioeconomic development, support a wide range of economic activities and are vital for human survival. The availability and management of these resources often dictate a nation’s prosperity and societal wellbeing [8]. Agriculture, which consumes about 70% of the world’s freshwater, epitomizes the economic dependence on water. It forms the economic mainstay of many developing countries, where a significant proportion of the population relies on farming. In regions such as Sub-Saharan Africa and parts of Asia, where water scarcity is a pressing issue, the absence of reliable water sources can drastically impede agricultural productivity, leading to food insecurity, poverty, and economic stagnation [9]. Conversely, effective water management can enhance agricultural output, improve food security, and stimulate economic growth. Beyond agriculture, water is integral to various industrial processes, emphasizing the economic consequences of water resource management [10]. A lack of sufficient or reliable water can disrupt industrial operations, dampen economic output, and result in job losses, whereas sustainable water management can encourage industrial growth and economic resilience [11].

Water resources significantly contribute to societal wellbeing by supporting a range of essential services [12]. One of the most vital is sanitation, where water is used to maintain cleanliness and prevent disease spread. Access to clean water and sanitation facilities is a fundamental human right and a crucial indicator of societal progress [13,14]. Yet, as of 2021, an estimated 2.2 billion people globally still lack access to safely managed drinking water, and 4.2 billion are without safely managed sanitation services [15]. This stark reality underscores the societal implications of water resource management and the urgent need for solutions that expand access to clean water and sanitation services. Additionally, water quality directly impacts human health, with contaminated water being a primary cause of diseases such as cholera, dysentery, and typhoid [16,17,18,19]. Water resources also enhance recreational activities and mental health, offering spaces for relaxation, exercise, and connection with nature. They play a pivotal role in maintaining environmental sustainability, supporting biodiversity, regulating the Earth’s climate, and acting as a buffer against climate change [20,21,22].

Considering the pivotal role of water resources in socioeconomic development, it is crucial to examine their relationship with sustainable development. This involves understanding the complex interplay between water availability, quality, usage, and the socioeconomic factors that influence these dynamics. It also requires exploring innovative strategies for water resource management that balance societal, economic, and environmental needs [23,24]. This Special Issue on “Water Resources and Sustainable Development” in Water aims to address these critical areas. It brings together a collection of research that provides fresh insights into the challenges and opportunities in water resource management for sustainable development. The studies presented in this issue cover diverse geographies and contexts, offering a comprehensive view of the current state of knowledge in the field. With the publication of this Special Issue, we aim to stimulate further research and dialogue on this vital topic, contributing to global efforts towards achieving water security and sustainability.
