A Macroinvertebrate Bioassessment Index for Headwater Streams of the Eastern Coalfield Region, Kentucky
source: https://www.academia.edu
Determining the ecological health of streams is a major focus of the various aquatic-monitoring programs in the Kentucky Division of Water (KDOW). This effort is mandated by the U.S. Envi[1]ronmental Protection Agency (EPA) under the Clean Water Act (CWA) and integrates the collec[1]tion of physical, chemical, and biological elements to assess water pollution. Since the turn of the century, aquatic organisms have been used extensively in water quality monitoring and impact as[1]sessment (reviewed by Cairns and Pratt 1993), and macroinvertebrate assemblages have proven to be useful in detecting even subtle changes in habitat and water quality. To accurately characterize patterns of stream degradation, impact assessment procedures must be based on sound ecological principles and the ability to feasibly measure the response of a macroinvertebrate community to disturbance.

Tackle Environmental Challenges in Pollution Controls Using Artificial Intelligence: A Review
This review presents the developments in artificial intelligence technologies for environmental pollution controls. A number of AI approaches, which start with the reliable mapping of nonlinear behavior between inputs and outputs in chemical and biological processes in terms of prediction models to the emerging optimization and control algorithms that study the pollutants removal processes and intelligent control systems, have been developed for environmental clean-ups. The characteristics, advantages and limitations of AI methods, including single and hybrid AI methods, were overviewed. Hybrid AI methods exhibited synergistic effects, but with computational heaviness.

Water In The Green Economy
Abstract
Water and its management is becoming not just a local but a global priority. The UN Rio+20 Declaration emphasises the need to establish a green economy as the means to achieving sustainable development while protecting and improving the world’s natural resources. Water is increasingly seen as a central plank of the green economy. It is embedded in all aspects of development – food security, health, and poverty reduction – and in sustaining economic growth in agriculture, industry, and energy generation.

Managing Forests and Water for People under a Changing Environment
Forests cover 30% of the Earth’s land area, or nearly four billion hectares. Enhancing the benefits and ecosystem services of forests has been increasingly recognized as an essential part of nature-based solutions for solving many emerging global environmental problems today. A core science supporting forest management is understanding the interactions of forests, water, and people. These interactions have become increasingly complex under climate change and its associated impacts, such as the increases in the intensity and frequency of drought and floods, increasing population and deforestation, and a rise in global demands for multiple ecosystem services including clean water supply and carbon sequestration. Forest watershed managers have recognized that water management is an essential component of forest management. Global environmental change is posing more challenges for managing forests and water toward sustainable development. New science on forest and water is critically needed across the globe.

Elimination of Infectious Diseases from the South-East Asia Region
This book discusses the historical context, country experience, and best practices that led to eliminating infectious diseases from the WHO’s South-East Asia Region, such as malaria, lymphatic filariasis, yaws, trachoma, and mother-to-child HIV in the mid-twentieth and twenty-first century. The UN Sustainable Development Goals (3.3) targets to end AIDS, tuberculosis, malaria, and neglected tropical diseases and combat hepatitis, water-borne diseases and other communicable diseases by 2030. In this context, this book is of high significance to countries from the SEA region and around the globe. It helps create national strategies and action plans on infectious disease elimination and thus attaining SDG 3.3. This is an open access book.

Remote Sensing of the Aquatic Environments
The book highlights recent research efforts in the monitoring of aquatic districts with remote sensing observations and proximal sensing technology integrated with laboratory measurements. Optical satellite imagery gathered at spatial resolutions down to few meters has been used for quantitative estimations of harmful algal bloom extent and Chl-a mapping, as well as winds and currents from SAR acquisitions. The knowledge and understanding gained from this book can be used for the sustainable management of bodies of water across our planet.
