In this chapter root anatomical traits and trait states, and nutrient acquisition mechanisms, along with the environmental issues affecting nutrient acquisition are summarized. Then, the whole range of adaptations of root anatomical traits, and its impact on nutrient acquisition are discussed. Combinations of anatomical traits lead to suggestions of root ideotypes potentially capable of supporting agricultural productivity under different edaphic constraints. Spatiotemporal aerenchyma formation in the various root types of maize under nitrate, phosphate or sulfate deprivation is discussed in a case study.

Controversy is common on environmental issues, with carbon taxation in Canada a current example. This paper uses Canada as a case study for analysis based around balanced presentation, a technique developed some time ago, yet largely forgotten. Using the method, analysis is shifted away from the point of controversy to a broader quantitative question, with comparative data employed from official government sources. Simple quantitative analysis is applied to evaluate emission trends of individual Canadian provinces, with quantitative metrics to identify and confirm the application of relevant emission reduction policies by individual jurisdictions. From 2005 through 2019, three provinces show consistent downward emission trends, two show consistent upward trends, and the remaining five have no trends, showing relatively “flat” profiles. The results clarify, in terms of diverse emission reduction policies, where successes have occurred, and where deficiencies or ambiguities have existed. Neither carbon taxation nor related cap-and-trade show any association with long-term reductions in overall emissions. One policy does stand out as being associated with long-term reductions, namely grid decarbonization. The results suggest a possible need within Canada to rethink emission reduction policies. The method may be relevant as a model for other countries to consider as well.

The benefits from educational travel programs (ETPs) for students have been well-documented in the literature, particularly for programs looking at sustainability and environmental issues. However, the impacts the ETPs have on the destinations that host them have been less frequently considered; most of these studies focus, understandably, on destinations in the Global South. This paper draws on a framework of sustainable educational travel to examine how ETPs affect their host destinations in two case study destinations, based on the author’s professional experience in these locations, interviews with host organizations that use the lens of the pandemic, and information from government databases. The findings highlight an awareness of the sustainability of the destination, the importance of good, local partnerships with organizations well-connected in their communities, and educational activities that can benefit both students and hosts. Nonetheless, we have a long way to go to understand the full impacts of ETPs on their host destinations and thus truly learn to avoid them.

Removal Of Metal

As the feature size of semiconductor device shrinks continuously, various high-K metals for 3-D structures have been applied to improve the device performance, such as high speed and low power consumption. Metal gate fabrication requires the removal of metal and polymer residues after etching process without causing any undesired etching and corrosion of metals. The conventional sulfuric-peroxide mixture (SPM) has many disadvantages like the corrosion of metals, environmental issues etc., DSP+(dilute sulfuric-peroxide-HF mixture) chemical is currently used for the removal of post etch residues on device surface, to replace the conventional SPM cleaning [. Due to the increased usage of metal gate in devices in recent times, the application of DSP+chemicals for cleaning processes also increases [.

Waste Bank

This research focuses on how leadership has a major role in addressing environmental issues, especially through the garbage bank program as a form of case study. Furthermore, the problems that occur in the midst of society are often rely solely on political will or political desire to solve them. The research is to know and learn Lurah's (head of village) leadership in the management of waste banks specifically. This research is qualitative descriptive research. Data collection techniques through structured interviews, documentation and observations. Researchers conducted an analysis using leadership theory from Yukl, where the theory discusses leadership comprehensively. Researchers only focus on five parts of the concept that are considered relevant, namely: visionary, guidance, affiliative, democratic and communicative concepts. The results of this study based on these dimensions are good enough Lurah (head of village) leadership. But there are several things that are considered able to optimize the running of the program through the role of Lurah (Head of village) leadership, namely: first, involving active knots and community leaders such as MUI, academics to support scientific aspects, and professionals in the field of practical management.

AbstractThe development of the regions in Slovakia in recent years has significant disparities in both so-cio-economic as well as environmental issues, as evidenced by the eight environmentally polluted areas (these areas are highly urbanised with industrial agglomerations or intensive agricultural production).This article deals with a management system model of regional by implementation of projects in environmental field of water management with application-specific benefits and risks arising from the process of their implementation in relation to regional development. It analyses projects in the area of water management of one of the regions of Slovakia, KoŠice region in particular, in terms of connection to public water duct and sewer, identifes a strategy for development of the region and its socio-economic and environmental benefits based on the analysis of drinking water, the quan-tity and quality of treated wastewater through wastewater treatment plants (WTPs). It identifes the infuencing factors of benefits and risks and proposes procedure for solving at various stages.

A reflexão sobre as práticas ambientais, em um contexto marcado pela degradação permanente do meio ambiente e do seu ecossistema, tem exigido novas posturas das organizações. Contudo, adotar a gestão ambiental como estratégia de desenvolvimento, contempla as necessidades das organizações em aliar crescimento econômico e sustentabilidade. Neste sentido, este artigo tem como objetivo identificar se existe a preocupação com as questões ambientais por parte das organizações da região da Quarta Colônia e se as mesmas adotam programas de gestão ambiental, analisando fatores que podem influenciar nas diferentes abordagens dadas ao tema. Para atingir o objetivo proposto, utilizou-se uma abordagem qualitativa em um estudo considerado exploratório e compreendido como estudo de caso. A amostra foi de cinco organizações da Região da Quarta Colônia onde foram realizadas visitas técnicas e entrevistas semi-estruturadas. Como resultado significativo do estudo, pôde se constatar que as organizações estudadas limitam-se apenas às exigências da legislação ambiental em vigor. Assim as organizações necessitam adotar novas posturas e um processo de atualização contínua que pode ser viabilizado pela gestão ambiental. Palavras-chave: Gestão ambiental; Quarta Colônia; organizações; desenvolvimento. Abstract The reflection about environmental practices, in a context marked by permanent degradation of the environment and its ecosystem, has required new strategies from the organizations. However, adopting environmental management as a development strategy satisfies the organizations needs to gather economic growth and sustainability. Thus, this paper aims on identifying whether the organizations from the Quarta Colonia Region are concerned about environmental issues and whether they adopt environmental management programs, analyzing aspects which can influence the different approaches applied to this issue. In order to reach such aim, a qualitative approach was used in a study considered exploratory and comprised as a case study. The sample consisted of five organizations from the Quarta Colonia Region where there were technical visits and semi-structured interviews. A relevant result of the study was that it was possible to observe that the studied organizations are restricted only to the operative environmental law requirements. Thus, organizations ought to adopt new emplacements and a continuous updating process, which can become viable through the environmental management.

The purpose of this paper is to discuss the role of insurance companies in solving environmental issues. Environmental issues we now face are many of such magnitude and severity that it is not just up to governments or heavy polluting companies to deal with them, everyone needs to contribute including authorities, institutions, corporations and individuals. Insurance systems differ between countries, but due to the size of the insurance sector and integration with almost every aspect oft society, insurers can be a powerful ally when it comes to implementing environment and climate policies of authorities. The article is based on a Ph.D. research of one of the authors which conducted a multi-case study of 16 Nordic insurance companies in the Åland Islands, Faroe Islands, Iceland, Denmark, Finland, Norway, and Sweden. The companies are divided into two case groups; the Islands group and the Mainland group. Differences in actions/inactions were evident between the case groups, meaning that most of the examples used are from the Mainland group. The environmental and climate change focus areas of the Mainland group are 1) products and services, 2) loss prevention and claim settlement, 3) investments, 4) companies own operation, 5) follow-up, and 6) insurers as a driving force of actions. In case of the Islands companies they mainly focus on loss prevention and few factors that affect their daily activities. Theoretical and practical contribution of the study is to highlight the role and contribution of insurance companies in dealing with environmental issues.
