Summary

Environmental science emerged from the fields of natural history and medicine during the Enlightenment. Today, it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems. Environmental studies are incorporating more of the social sciences in order to understand human relationships, perceptions and policies towards the environment. This entry collection features information about design and technology for improving environmental quality in every aspect.

Pre-Emptively Managing Overtourism
Overtourism is the congestion or overcrowding from an excess of tourists, resulting in conflicts with locals. The World Tourism Organization defines overtourism as "the impact of tourism on a destination, or parts thereof, that excessively influences perceived quality of life of citizens and/or quality of visitor experiences in a negative way".

Sustainable Development and Mangroves
Mangroves are salt-tolerant trees that inhabit the mid and upper intertidal coastal fringes (mainly estuaries and deltas) of tropical and subtropical regions. Rainfall, tidal height, salinity, soil characteristics (nutrients and oxygen content, grain composition and humidity), and biotic factors, like herbivory, are among the main ecological factors determinant of their development, diversity, and high biomass .

Gamified Waste Management Tool
Waste management is an increasingly visible and essential element to functioning civilization. However, while the theory of waste management is studied widely, waste management remains for many a difficult concept to understand. There is an opportunity to create an informative, easy-to-use simulator to help all types of individuals build an understanding of waste management and to evaluate the impact of various changes on waste management performance, particularly in the context of gamified tools.

Ecological Footprint for the Algerian Fisheries Management
According to the estimated ecological footprint (EF) of fishery production (EFf), Algiers fishing is in the status of ecological surplus, as the demand for fisheries production averages 15,338.49 gha compared to more than 108 thousand gha of biologically productive fishing area. In addition to this overall output, this metric indicates each species’ primary production requirement (PPR), which could help to restructure the fishing effort based on the stock’s condition. For the energy component, the fuel consumption and greenhouse gas (GHG) emissions expressed in metric tons of CO2 were used to estimate the required area for carbon sequestration, valued roughly at 500 gha. The latter is a reference state and remains approximate because it was derived from unofficial data provided by the fishers.

Comparison of Road Noise Policies
Developing innovative noise policies that build on international best practices is difficult when policies around the world differ along many dimensions, ranging from different sources covered to different levels of governance involved. This is particularly critical in the context of road traffic, identified as one of the main culprits leading to noise-associated complaints and health issues.

Beach Drainage System
The idea that the groundwater table plays a role in the mobilization of the sediment grains underlies the application of the beach drainage system (BDS) as a tool able to modify the natural dynamics of groundwater table at sandy beaches. The beach drainage is one of the soft engineering methods aimed to counteract the shoreline retreat related to the sediment redistribution along the beach profile.

Authorized Valuation Activity in Romania
A formal valuation process involves a professional reasoning based on a systematic analysis and appreciation of the value, importance, performance, merit, efficiency, effectiveness, capacity, quality of an asset, either a person or entity, resource, tangible/intangible assets, service, plan, program, situation, event, etc. This reasoning starts from a set of collected data and is carried out by reporting to a desirable level, set by specific standards.

Cadmium Recovery from Spent Ni-Cd Batteries
The significant increase in the demand for efficient electric energy storage during the last decade has promoted an increase in the production and use of Cd-containing batteries. On the one hand, the amount of toxic Cd-containing used batteries is growing, while on the other hand, Cd is on a list of critical raw materials (for Europe). Both of these factors call for the development of effective technology for Cd recovery from spent batteries. Alkaline nickel-cadmium (Ni-Cd) batteries are widely used as autonomous sources of industrial and household current (power banks) due to a successful combination of feasibility studies and achieved sustainable electrical characteristics. In recent decades, the market of secondary current sources for portable equipment has undergone significant changes, which leads to an intensive replacement of Ni-Cd batteries with lithium-ion (LIB) and nickel-metal-hydride.
