Water and Wastewater: Filters
Published in Brian D. Fath, Sven E. Jørgensen, Megan Cole, Managing Water Resources and Hydrological Systems, 2020
Engineering applications of ecological principles and succession of biological communities are very useful inconsuming organic and inorganic pollutants from the water and bioconverting them into nontoxic form.[30,31] The consortia of organisms at different trophic levels utilize pollutants as nutrients. These eco-transformations, eco-conversions, and degradation or bioutilization of pollutants to nutrients are part of ecological and biogeochemical cycles. An attempt has been made to apply natural flora and fauna in a well-designed manner to develop technologies like Green Bridge, Green Lake Eco-Systems, Green Channel, BIOX (Biological Oxidation) and Stream Eco-Systems.
Sustainable Agriculture: Soil Quality
Published in Brian D. Fath, Sven E. Jørgensen, Megan Cole, Managing Soils and Terrestrial Systems, 2020

Agriculture benefits from biodiversity in many ways, but it has also reduced biodiversity over the years, mainly through the conversion of natural habitats, but also through effects on soil and water quality. Improving soil quality not only maintains a healthy biological community in the soil itself, along with the functions these organisms carry out, but also supports the other flora and fauna dependent on this community. Soil quality improvements that benefit water quality can also improve the viability of aquatic ecosystems.

Ethiopia is among the few countries in the African continent where major types of natural vegetation are demonstrated ranging from thorny bushes to tropical forests and mountain grasslands (Othow et al., 2017). This is related to the country’s endowment with great geographical, cultural diversity and agro-climatic variability. The flora of Ethiopia comprises 6027 vascular plant species of which 10% are endemic (Ensermu & Sebsebe, 2014). The availability of such diverse flora provides goods and services of significant value to the society, environment and economy. Forests are key components of biodiversity and important sources of livelihood for millions of people that serve as sources of food, medicine, rain, clean water, air, reservoir for wildlife and carbon particularly in reducing climate change impacts (FAO, 2016). Though forests play such critical environmental, social and economic roles for the sustainability of life on earth, the quantity and quality of forests in Ethiopia are declining from time to time (Gurmessa, 2015; Keenan et al., 2015).
Germination and seedling growth of the Chilean native grass Polypogon australis in soil polluted with diesel oil

The global consumption of diesel fuel is a causal of several environmental risks that affect soil and water (Neff et al. 2000). Diesel oil in soil affects plants nutrients availability, and diesel components affect germination and growth of plants (Adam and Duncan 2002; Siddiqui and Adams 2002; Ogbo 2009). Phytoremediation has proven to be efficient in lowering the environmental risks of organic pollutants. Some plant species can render the toxic compounds in diesel unavailable for other organisms by extracting, degrading, stabilizing and/or enhancing bacterial populations on the rhizosphere (Frick et al. 1999). Research on phytoremediation of organic pollutants has shown that plants belonging to the family of Poaceae are organisms of interest for remediation of soils contaminated with petroleum hydrocarbons (Adam and Duncan 2002; Ogbo et al. 2009; Odokuma and Ubogu 2014). The tolerance of a species to the contaminant is a relevant parameter when selecting plants for phytoremediation. Concurrently, it is important to consider the use native flora in order to minimize the ecological impact of using exotic species (Nouri et al. 2011). Of particular interest are plants that colonize and settle in contaminated environments, since they exhibit plasticity and develop cross-tolerance to stresses of the same or different nature (Yoon et al. 2006; Walter et al. 2013).
