This study demonstrates the antecedents and challenges of innovation in sustainable development (SD) projects. In particular, a systematic literature review is conducted to highlight the challenges of innovation, that can suppress the efficient attainment of innovation benefits, in SD projects. The findings indicate that the positive benefits of innovation, in SD projects, are applying new strategies, developing new management practices, increasing interests and commitments of project team members, obtaining a better quality, attaining competitive advantages, introducing active influencers, establishing more engagement and collaborative work among team members, and satisfying project stakeholders. On the other side, innovation challenges that could act as barriers to achieve these benefits, in SD projects, are innovation resistance, stakeholders‟ requirements, pressure from clients to meet the SD project goals, diverse project environment, dynamic and unstable markets, project structure and characteristics, compliance with the common goals between innovation and sustainable development projects, and less management support and commitment for innovation. In brief, if project team members could overcome these challenges, innovation could be adopted and implemented effectively in sustainable development projects.

With its 258,509 inhabitants (INS, 2014. 27), Daloa, the third largest city in Côte d'Ivoire, has experienced an urban growth rate of 2.73% (op cites). But over the years, the locality has been confronted with an uncontrolled urban dynamic which has environmental repercussions on its landscape. Measures and actions are daily announced by the public authorities to eradicate this phenomenon, but the change is still virtual. This study aims to identify the persistence of environmental degradation in the city of Daloa. The methodology for conducting this study was based on a set of technical approaches. This is documentary research focusing mainly on scientific work and study reports addressing the issue of uncontrolled urbanization and its environmental effects. In addition to this approach, direct observation and interviews with local resource people were used. A questionnaire survey was also conducted with 373 heads of household using the probabilistic formula without Environmental Management and Sustainable Development ISSN 2164-7682 2021, Vol. 10, No. 1 http://emsd.macrothink.org 61 replacement in 1/3 of the enumeration areas totaling 13 neighborhoods. The results show that the deterioration of the urban environment in Daloa is experienced by households in the form of pollution caused by rainwater, wastewater and sluices (47%.), Pollution due to household waste (24% ), air (15%) and noise (14%) pollution. The factors are plural and reveal that 58% of the households surveyed dispose of their used water (detergents, dishes) on the street and 48% dump household waste on the streets. The impact on the urban landscape is just as diverse and unpleasant. Rainwater on unpaved roads accelerates erosion. The flow of open sewage and piles of rubbish, undermine the aesthetics of the urban landscape of Daloa.

In the last few decades, there has been increased worldwide awareness of the necessity to consider development from a holistic perspective, for human development without adequate environmental protection is undermined. Cameroon, like many other developing countries has made great strides in establishing and putting in place an environmental assessment system to mainstream environmental concerns into development initiatives. The full realization of this goal, however, depends on the effectiveness of the exercise which hinges principally on the provisions of relevant legislation, the institutional framework, the procedure and practice of the assessment process. Environmental assessment in many developing countries is fraught with a plethora of setbacks which can jeopardize the full contribution of the exercise to the attainment of the sustainable development goals, if not taken care of. Based on experience and field research, this study examines the current practice of environmental assessment in Cameroon, the difficulties encountered in developing countries, the chances of environmental assessment contributing to sustainability and makes recommendations on how to improve the practice in developing countries.

Kamrangirchar is a raised land and industrial area situated on the bank of the Buriganga River in Dhaka city. The industries of this area are producing a huge amount of solid and liquid wastes all of which are disposed into the Buriganga river and other nearby places. This study attempts to explore the scenario of industrial waste management in Kamrangirchar (raised land) and its effect on the surrounding environment. The methodology of this study includes in-depth interviews and tries to explore the ways of managing waste properly. This study tries to explore more effective ways of managing industrial waste for a sound and safe environment. Environmental pollution has been a major global problem nowadays. Nature is being destroyed because of the excessive exploitation of the environment. Some elements of the environment and ecology like forests, natural sources of water, land, and air are gradually being polluted in Bangladesh, although these are essential for survival. Lack of awareness of the industrial units, poor implementation of the government policy of industrial waste management, inappropriate initiatives to dispose of the waste properly, and ineffective laws are responsible for the improper management of industrial waste in Kamrangirchar which is affecting the environment directly and indirectly.

This study was carried out to determine the concentration of chemical elements in food grains (Oryza Sativa). A total of eight brands of rice grains was selected which are commonly sold in major hypermarkets in Malaysia. The selection was based on the countries of origin (COO) namely Cambodia, Indonesia, Malaysia, Thailand, Vietnam, China, Japan and Taiwan. A total of 16 rice grain samples included both polished and unpolished rice grains in order to determine the concentration of Fe, Zn, As, Cd and Pb. From the laboratory result, it was found that the concentration of Fe, Zn, As, Cd and Pb was ranged from 0.067-14.446 mgkg -1 , 0.308-12.335 mgkg -1 , 0.000-0.048 mgkg -1 , 0.000-0.604 mgkg -1 and 0.000-0.418 mgkg -1 respectively. The rice grains samples from Vietnam, China and Cambodia showed that carcinogenic cancer risk for both adults and infants’ group (Cumulative lifetime cancer risk, CLCR >1x10 -4 ).

While there has been a substantial amount of literature published on environmental beliefs and behaviors, cross-cultural research in this area, particularly comparisons between indigenous vs. non-indigenous people, remains limited. The current study conducted a comparison of the environmental beliefs and behaviors, as well as political attitudes, between an indigenous and a non-indigenous sample of New Zealand and the US (total n =322). Respondents included students at the University of Waikato in New Zealand (Māori and European New Zealanders) and the University of North Carolina Pembroke in the US (Lumbees and non-indigenous Americans). The participants provided responses regarding their ecological worldview, belief in global climate change, and participation in environmentally responsible behaviors as well as their political attitudes, including system justification and political liberalism. Results showed that the New Zealand sample was more politically liberal and demonstrated more environmentally friendly beliefs and behaviors than the US sample. The indigenous group did not differ in their environmental beliefs or behaviors from their non-indigenous counterpart, but did endorse less system justification. Mediation analyses indicated that ecological worldview and belief in global climate change together fully mediated the link between political liberalism and environmentally responsible behavior. Implications of these findings for environmental behavior research and education are discussed.

Cities emerged as international agents and started engaging in intercity cooperation as a mechanism to address global challenges through regional solutions and also join resources to tackle local challenges and fulfill their management responsibilities. Collaborative planning to improve environmental conditions is one of the possible scopes for international cooperation, as stakeholders can share multiple information, knowledge, technologies, and governance experience. However, despite the benefits in a multi-stakeholder scheme, building consensus in such a diversified setting is a complex, time-consuming process, to reach a shared understanding about a certain problem and possible ways to address it.During the last decade, the Japanese government, one of the largest world’s donors of gross ODA, has been increasing the funding activities to promote intercity collaboration for the development of more sustainable societies, engaging multiple stakeholders for a wide diversity of projects. This research had selected three international projects in Davao, supported by Kitakyushu, and identified four groups of major drivers and challenges (communication, political and institutional, financial, and technical) that can either foster or hinder consensus building among multi-stakeholders in the context of intercity cooperation for collaborative environmental planning.

The department of Bouafle is increasingly faced with health problems related to inadequate family sanitation. This situation creates high risks of high mortality and morbidity. In order to help significantly reduce these risks, EAA has initiated a project to promote family sanitation, ecological sanitation latrines (EcoSan) and the reuse of its by-products in agriculture in several villages in this department. The objective of this study is to assess the sustainability of ecological sanitation in rural areas in the said department. In order to achieve this objective, in addition to the literature review, this study was part of a mixed approach mobilizing related techniques and tools. The results obtained revealed that full latrine coverage and hand hygiene are not effective in all households.The factors contributing to the maintenance of the status of end of defecation in the open air in rural areas, especially the use of by-products in agriculture, are problematic. However, some of the households using the hygienized human excreta (HHE) show that crops fertilized by HHEs grow faster, the leaves of the plants are greener, have larger grains and fruits with a good taste when ripe. In addition, they control several pathogens, particularly Swollen Shoot in cocoa plantations.

Sai Gon river is one most the most important river of South-eastern region of Vietnam by providing water resources and others vital natural services for millions of people in this area. In recent years, proportion with the sharply increasing of human activities in industry and agriculture, the river is continuously loaded with xenobiotics released by anthropogenic activities. Among pollutants, heavy metals are considered as the most toxic elements to aquatic living organisms and human health. The aim of this study is to assess the sensibility of freshwater microalgae Scenedesmus and water flea Daphnia carinata , two fresh water species from Vietnam to copper (Cu). After physical and chemical characterization, field water samples from upstream Sai Gon River was used as dilution water in toxicity tests. With water flea D. carinata , the EC50 value of 48h immobilization experiment was 1.90 µg/L. Growth inhibition of the Scenedesmus algae cells was determined following exposure for 72 h, and EC50 values was 78.2 µg/L. The results showed that Cu is highly toxic to both species, and water flea D. carinata was more sensitive than freshwater algae Scenedesmus . Based on the observed high sensitivity with Cu, both D. carinata and algae Scenedesmus are potential tools for the assessment of copper pollution in fresh water of Sai Gon river.

This study aims to investigate the influence of organizational and process eco-innovations on the introduction of product eco-innovations in R&D-intensive companies. We covered theory gaps by empirically demonstrating to what extent non-technological and technological eco-innovations are related. We used the Survey method to investigate a sample of Brazilian manufacturers from the electrical and electronics sectors, and we processed the data through Structural Equation Modeling (SEM). The findings of this study evidenced that non-technological eco-innovations are able to influence technological eco-innovations, both Environmental Management and Sustainable Development ISSN 2164-7682 2020, Vol. 9, No. 4 http://emsd.macrothink.org 61 process and product, suggesting that the organizational eco-innovation strategy leads to sustainable technological path dependence in R&D-intensive companies. Additionally, findings demonstrated that the association between organizational and product eco-innovation is stronger whether mediated by process eco-innovation, so the result confirms an evolutionary perspective regarding the differentiated types of eco-innovation. We conclude that by investing in eco-innovative R&D projects, new environmental systems, teams' formation, information flow, and trends monitoring, the company creates a path dependence for technological eco-innovation of process and products.

We used the Survey method to investigate a sample of Brazilian manufacturers from the electrical and electronics sectors, and we processed the data through Structural Equation Modeling (SEM). The findings of this study evidenced that non-technological eco-innovations are able to influence technological eco-innovations, both Environmental Management and Sustainable Development ISSN 2164-7682 2020, Vol. 9, No. 4 http://emsd.macrothink.org 61 process and product, suggesting that the organizational eco-innovation strategy leads to sustainable technological path dependence in R&D-intensive companies. Additionally, findings demonstrated that the association between organizational and product eco-innovation is stronger whether mediated by process eco-innovation, so the result confirms an evolutionary perspective regarding the differentiated types of eco-innovation. We conclude that by investing in eco-innovative R&D projects, new environmental systems, teams' formation, information flow, and trends monitoring, the company creates a path dependence for technological eco-innovation of process and products.","PeriodicalId":408586,"journal":{"name":"Environmental Management and Sustainable Development","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115695056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
