Human-induced water impacts refer to the alterations and modifications humans make to the natural water systems on Earth, resulting in significant changes to water availability, quality, and overall ecosystems. These impacts can occur at various scales, from local to global, and are a consequence of human activities such as agriculture, industry, urbanization, and resource extraction. One of the most significant human-induced water impacts is water scarcity. The growing global population and increasing water demand for agriculture, industry, and domestic use have put tremendous pressure on freshwater sources. Over-extraction of water from rivers, lakes, and aquifers has led to depletion and the drying up of many water bodies, leaving communities and ecosystems struggling to meet their water needs. Water pollution is another major consequence of human activities. Industrial waste, agricultural runoff, and improper disposal of chemicals and waste products contaminate water sources, making them unfit for consumption and harmful to aquatic life. This pollution can have long-lasting effects on ecosystems, disrupting natural balances and causing the loss of biodiversity. Furthermore, the alteration of natural water flow patterns through dam construction and river channelization can have profound impacts. While these interventions serve purposes such as hydroelectric power generation and flood control, they can disrupt aquatic habitats, alter sediment transport, and hinder the migration of fish and other species, ultimately affecting the entire ecosystem. Mitigating human-induced water impacts requires sustainable water management practices, including efficient water use, pollution control measures, and the protection and restoration of natural water systems. Adopting these practices is crucial to ensure the availability of clean water for both current and future generations, as well as to maintain the health and integrity of freshwater ecosystems.

The edited volume brings out a comprehensive collection of information relevant to wild food plants, their importance for global sustainable food security, future-readiness, and resilient agriculture. The book's primary focus is to cover topics on the diversity of wild food plants across the globe, their nutraceutical importance, production-consumption trends, integration into the current food menu, and marketing and livelihood opportunities to the indigenous people. Sustainable development goals 1, 2, and 3 are significant for a poverty-free, hunger-free world and ensure good health and wellbeing of the people, respectively. The three goals are important and interlinked as achieving zero poverty will help reduce hunger among the people. Availability of nutritional and balanced food ensures good health. Wild food plants are an essential part of a nourishing and healthy diet for indigenous communities. They are globally collected from natural habitats or cultivated at more minor scales. Although consumed locally, they are an essential part of the diets of tribal and indigenous communities worldwide and hold immense potential to alleviate global hunger. Considering their importance for global sustainable food security, it is essential to clearly understand the future role of wild food plants for future readiness and resilient agriculture. Therefore, this book provides a piece of important information on these aspects. The book is a valuable resource for the audience ranging from undergraduate science students to the NGOs and institutions involved in poverty alleviation programs, policymakers, dieticians, horticulturists, plant breeders, farmers, health experts, and food enthusiasts.
