Arsenic Remediation
Arsenic contamination of the environment is a serious problem threatening the health of millions of people exposed to arsenic (As) via drinking water and crops grown in contaminated areas. The remediation of As-contaminated soil and water bodies needs to be sustainable, low-cost and feasible to apply in the most affected low-to-middle income countries, like India and Bangladesh. Phytoremediation is an aesthetically appreciable and successful approach that can be used for As decontamination with use of the best approach(es) and the most promising plant(s). However, phytoremediation lacks the required speed and sometimes the stress caused by As could diminish plants’ potential for remediation. To tackle these demerits, we need augment plants’ potential with appropriate technological methods including microbial and nanoparticles applications and genetic modification of plants to alleviate the As stress and enhance As accumulation in phytoremediator plants.

Soil Nanomanagement and Mushrooms
Soil is the main component in the agroecosystem besides water, microbial communities, and cultivated plants. Several problems face soil, including soil pollution, erosion, salinization, and degradation on a global level. Many approaches have been applied to overcome these issues, such as phyto-, bio-, and nanoremediation through different soil management tools. Mushrooms can play a vital role in the soil through bio-nanoremediation, especially under the biological synthesis of nanoparticles, which could be used in the bioremediation process.

Mechanism of Microalgal Phycoremediation
Microalgae are continually exposed to heavy metals and metalloids (HMMs), which stifles their development and reproduction due to the resulting physiological and metabolic abnormalities, leading to lower crop productivity. They must thus change their way of adapting to survive in such a hostile environment without sacrificing their healthy growth, development, reproductive capacity, or survival. The mode of adaptation involves a complex relationship of signalling cascades that govern gene expression at the transcriptional and post-transcriptional levels, which consequently produces altered but adapted biochemical and physiochemical parameters. Algae have been reported to have altered their physicochemical and molecular perspectives as a result of exposure to a variety of HMMs.

The African Ecological Futures
The African Ecological Futures (AEF) planning project, a joint initiative between the African Development Bank (AfDB) and the Worldwide Fund for Nature (WWF) that took place between 2013 and 2015, is an example of how participatory scenario planning can benefit the continent. The process involved a series of analytical studies combined with workshops with policy makers and development partners with skill sets ranging from conservation and ecology to economics and international development. The outcomes of these workshops were four expert-developed and collectively-owned scenarios for the evolution of Africa’s ecological resource base over the next 50 years (2015–2065).

Ecological Compensation and Ecosystem Function Offsets
Ecological compensation, which is widely applied, is presumed to be an important mechanism to address environmental degradation that commonly occurs due to activities related to development projects and resource use. In comparison to carbon offsets, the implementation of biodiversity offsets are more challenging due to difficulties in biodiversity measurement, determining ecological equivalence, the relatively longer time taken, the higher level of uncertainty, the uniqueness of ecosystems, and the irreversibility of species loss. Generally, there is a positive relationship between biodiversity and carbon stocks; however, there are also cases where there are no clear or even negative relationships between biodiversity and carbon stocks. Ecosystem functions are directly or indirectly affected by environmental degradation, and ecological compensation measures usually compensate for only a few components of the ecosystem functions.

Biological Pollution of Indoor Air, Its Assessment and Control Methods
The aim of the entry was to write a substantial contribution that analyses and compares the biological pollution of indoor air, the possibilities of its assessment and the control methods. In addition, the aim of our entry was to review journals covering both commercial and residential buildings. By analysing the above topics from the existing articles, one can have the impression that air pollution is one of the most important problems that need to be solved in the modern world. Adequate air quality is important for maintaining human health, affects the health of ecosystems, including animals, and determines crop production. With the development of civilisation, the quality of air in the atmosphere and indoors is constantly deteriorating. Indoor air pollution can be divided into physical (e.g., noise, inadequate lighting, ionising radiation), chemical (e.g., tobacco smoke, household products) and microbiological (bacteria, viruses, fungi and products of their metabolism) factors. Each of these factors can have a negative impact on a person’s health or cause premature death. The entry deals with indoor air pollution, focussing on biological pollutants. It compares different methods available and describes the method of sampling to analyse indoor air pollution and ways to reduce it.

Climate Change in the Caribbean
Anthropogenic climate change is caused by the rapid increase of greenhouse gases in the atmosphere principally from burning fossil fuels, converting forestland to pasture and monoculture cropland, with the greatest contributions happening in the period since the Industrial Revolution. Climate change could pose disadvantageous risks to the islands in the Caribbean. The environmental changes expected to affect the Caribbean are a rise in sea level, stronger hurricanes, longer dry seasons and shorter wet seasons. As a result, climate change is expected to lead to changes in the economy, environment and population of the Caribbean.

Applications of Nanostructured Bioaerogel in Particulate Matter Removal
Particulate matter (PM) pollution is a significant environmental and public health issue globally. Exposure to high levels of PM, especially fine particles, can have severe health consequences. Conventional air filters are fabricated from non-biodegradable and non-ecofriendly materials which can cause further environmental pollution as a result of their excessive use. Nanostructured biopolymer aerogels have shown great promise in the field of particulate matter removal. Their unique properties, renewable nature, and potential for customization make them attractive materials for air pollution control.

Freshwater Invertebrates in Biomonitoring
Invertebrates are excluded from ethical consideration in the procedures of environmental protection, which results in the killing of many more individuals during sampling than necessary. Biomonitoring is used as a routine method for environmental protection that results in the cruel death of even millions of aquatic animals annually.

Hydrology and Cranes Attraction Partnership
The Hula Valley in northern Israel was partly covered by swamps and a shallow lake. The entire valley was drained and converted for agricultural cultivation. Later, an additional soil reclamation operation was implemented, including eco-tourism. From the early 1990s, winter migratory cranes have attracted visitors, thus supporting the hydrological management of the entire valley that protects the downstream Lake Kinneret.

Contemporary Methods of Measuring Methane Emission from Ruminants
Methane is the second most important anthropogenic greenhouse gases (GHG) in terms of global warming potential (GWP) and quantity and is responsible for 20% of the global warming caused by anthropogenic GHG emissions. The global annual CH4 emission from ruminant livestock is estimated to be between 80 and 95 million tons. Methane (CH4) production is also a loss of energy availability to the host ruminant animal, normally representing between 2% and 12% of the total gross energy intake, depending on the level of intake and diet composition. There is immense interest to develop an accurate ruminant CH4 emission of accounting to reduce the negative effects of GHGs on the environment and to evaluate mitigation strategies. Several methods have been developed to measure CH4 emissions from ruminants.

SIFT-MS for Volatile Organic Compounds Pollution Monitoring
The pollution of air and water with volatile organic compounds (VOCs), both hazardous and odorous, is of significant concern due to impacts on human health and quality of life, as well as the environment. The selected ion flow tube mass spectrometry (SIFT-MS) technique has been increasingly adopted to monitor source emissions and their dispersion, enabling a more rapid response to pollution incidents. To this end, the flexibility of SIFT-MS instrumentation for both laboratory- and field-based analysis, including in mobile laboratories, has been valuable.

Microbial in Total Petroleum Hydrocarbon Polluted Soils
Nowadays, soil contamination by total petroleum hydrocarbons is still one of the most widespread forms of contamination. Intervention technologies are consolidated; however, full-scale interventions turn out to be not sustainable. Sustainability is essential not only in terms of costs, but also in terms of restoration of the soil resilience. Bioremediation has the possibility to fill the gap of sustainability with proper knowledge. Bioremediation should be optimized by the exploitation of the recent “omic” approaches to the study of hydrocarburoclastic microbiomes. To reach the goal, an extensive and deep knowledge in the study of bacterial and fungal degradative pathways, their interactions within microbiomes and of microbiomes with the soil matrix has to be gained.

Water-Energy Nexus in Africa
The operationalization of the Water-Energy Nexus in the water supply is gaining  a lot of attention among water utilities, water regulators and stakeholders in the water sector. This is due to the growing body of evidence on the potential benefits of exploration of potential energy savings in the supply of water services, as the largest controllable operational input with short payback periods on investment. As population grows, high urbanization and the demand for water services increases especially in Africa, water utilities are faced with the challenges of meeting the current demand and expansion of services. However, there is paucity in the assessment of energy input for water supply and energy use is not considered as a key performance indicator for water utilities. Yet, accrued benefits from scrutinizing energy input in the water sector provides potential benefits of savings, revenue recovery and expansion of water services.
