AbstractFeeding management in dairy animals is crucial for ensuring optimal production apart from making the farming as a whole, a more sustainable activity. In our study we evaluated the production and environmental effects of two different feeding regimens i.e., one dominated by traditional cottonseed meal (CSM) and other with coated urea (slow release urea - SRU) as a replacement for CSM on dairy buffalo production. The SRU at 2% level was evaluated by conducting two different trials using twelve lactating Murrah buffaloes and four adult Murrah buffalo bulls. Neither diet nor dry period management showed any substantial effect on milk components, intakes, nutrients’ digestibility coefficients, and nutritive values. The SRU diet revealed increased (P < 0.01) rumen pH, ammonia nitrogen, volatile fatty acids, and microbial nitrogen yield, which were interacted with time of post-prandial sampling. The dynamics of nitrogen metabolism revealed unaltered N-based parameters, except for degradable-N intake and serum urea-N at 3 hr post-feeding. The CSM replacements did not influence (P > 0.05) the residual feed intake, but led to an enhanced milk retention efficiency of nitrogen, calcium, and phosphorus contents, thus reducing their impact on soil pollution and eutrophication of water bodies. Despite an unaltered (P > 0.05) enteric methane emission, SRU diets achieved in decreasing manure methane and nitrous oxide emission. Furthermore, the virtual water flow and lifecycle assessment revealed a water sparing effect and low carbon foot print per unit milk production. In summary, the CSM replacements with SRU could achieve an economical and eco-friendly production system from animal nutrition perspective.

Wine producers face several challenges regarding climate change, which will affect this industry both in the present and the future. Vulnerability assessments are at the forefront of current climate research, therefore, the present paper has two main aims. First, to assess two components of climate vulnerability regarding the Szekszárd wine region, Hungary; second, to collect and analyze adaptation farming techniques in terms of environmental sustainability aspects. Exposure analyses revealed that the study area will face several challenges regarding intensive drought periods in the future. Sensitivity indicators show the climate-related characteristics of the most popular grapevines and their relatively high level of susceptibility regarding changing climatic patterns. Since both external and intrinsic factors of vulnerability show deteriorating trends, the development of adaptation actions is needed. Adaptation interventions often provide unsustainable solutions or entail maladaptation issues, therefore, an environmental-focused sustainability assessment of collected interventions was performed to avoid long-term negative path dependencies. The applied evaluation methodology pointed out that nature-based adaptation actions are preferred in comparison to using additional machines or resource-intensive solutions. This study can fill the scientific gap by analyzing this wine region for the first time, via performing an ex-ante lock-in analysis of available and widely used adaptation interventions in the viticulture sector.

Inefficient and non-environmentally friendly absorbent production can lead to much resource waste and go against low carbon and sustainable development. A novel and efficient Mg-Fe-Ce (MFC) complex metal oxide absorbent of fluoride ion (F−) removal was proposed for safe, environmentally friendly, and sustainable drinking water management. A series of optimization and preparation processes for the adsorbent and batch experiments (e.g., effects of solution pH, adsorption kinetics, adsorption isotherms, effects of coexisting anions, as well as surface properties tests) were carried out to analyze the characteristics of the adsorbent. The results indicated that optimum removal of F− occurred in a pH range of 4–5.5, and higher adsorption performances also happened under neutral pH conditions. The kinetic data under 10 and 50 mg·g−1 were found to be suitable for the pseudo-second-order adsorption rate model, and the two-site Langmuir model was ideal for adsorption isotherm data as compared to the one-site Langmuir model. According to the two-site Langmuir model, the maximum adsorption capacity calculated at pH 7.0 ± 0.2 was 204 mg·g−1. The adsorption of F− was not affected by the presence of sulfate (SO42−), nitrate (NO3−), and chloride (Cl−), which was suitable for practical applications in drinking water with high F− concentration. The MFC adsorbent has an amorphous structure, and there was an exchange reaction between OH− and F−. The novel MFC adsorbent was proven to have higher efficiency, better economy, and environmental sustainability, and be more environmentally friendly.

The Brazilian Amazon frontier shows how remarkable leadership can work towards increased agricultural productivity and environmental sustainability without new greenhouse gas emissions. This is due to initiatives among various stakeholders, including national and state government and agents, farmers, consumers, funding agencies and non-governmental organizations. Change has come both from bottom-up and top-down actions of these stakeholders, providing leadership, financing and monitoring to foster environmental sustainability and agricultural growth. Goals to reduce greenhouse gas emissions from land-cover and land-use change in Brazil are being achieved through a multi-tiered approach that includes policies to reduce deforestation and initiatives for forest restoration, as well as increased and diversified agricultural production, intensified ranching and innovations in agricultural management. Here, we address opportunities for the Brazilian Amazon in working towards low-carbon rural development and environmentally sustainable landscapes.

Luxury is often blamed for creating social inequality and hampering sustainability, especially in the social and environmental realms. For instance, luxury goods entice people to conspicuous consumption that may result in showing off. However, study results show that luxury and environmental sustainability have common features. Notably, previous research mainly examined motivations for green purchases in general without relating to the specific product categories such as durables. Therefore, this study examines the relationship between these two—green and luxury automobile buying intentions—by analyzing the survey results of 1601 respondents relating to more than 60 nationalities. In contrast to a substantial effect on luxury buying intentions, perceived conspicuousness has no significant positive effect on green auto purchase intentions, and that price value has a limited influence compared with the effect on luxury automobile purchase intentions. Furthermore, hedonism has a less positive impact on green auto purchase intentions compared to its impact on luxury automobile buying intentions. The ‘extended self’ and the perception of high quality have been found to be drivers of luxury and green automobile purchase intentions, while unique value appears to have no impact on purchase intentions for green and conventional luxury automobiles. The present study contributes to the extant research by investigating common and contradictory motivations for luxury and green buying intentions of automobiles. Furthermore, it suggests a reconsideration of the traditional view that luxury and environmental consumption are inconsistent and contradictory concepts. The complementary managerial implications of this study guide practitioners in positioning the situatable variants of their automobiles as ethical luxury.

Energy development improves quality of life for humans, but also incurs environmental consequences. A global energy transition from fossil fuels to renewable energy may mitigate climate change but may also undermine the capacity to achieve some or all 17 Sustainable Development Goals (SDGs). In this study, we use an innovation systems approach to construct a comprehensive roadmap for solar and wind energy to anticipate and improve impacts of a transition to a low carbon future in a manner ensuring climate goals and SDGs are mutually reinforcing. Our multidisciplinary approach began with an assessment of public investments in renewable energy followed by a 2-day research prioritization workshop. Fifty-eight expert workshop participants identified six research themes that proactively address the environmental sustainability of renewable energy. Next, we identified linkages between the six research themes and all 17 SDGs. Finally, we conducted a scientiometric analysis to analyze the research maturity of these themes. The results of these efforts elucidated the limits of existing knowledge of renewable energy-SDG interactions, informing the development of a research, development, demonstration, and deployment (RD3) roadmap to a renewable energy future aligned with both climate goals and SDGs. The RD3 roadmap has been designed to systematically develop solutions for diverse actors and organizations. Overall, our findings confer a broad vision for a sustainable transition to renewables to minimize unintended environmental consequences while supporting interoperability among actors particularly poised to influence its magnitude and direction.

A comunidade científica, ao longo dos últimos anos, tem buscado soluções para o desenvolvimento sustentável do Semiárido. Os estudos dos impactos das mudanças climáticas subsidiam medidas de mitigação e adaptação frente às futuras alterações no clima. Adicionalmente, o desenvolvimento e adoção de processos e tecnologias voltados para o desenvolvimento sustentável, tendo em vista a viabilidade econômica, social e ambiental são fundamentais, para aumentar a segurança alimentar, gerenciar os recursos hídricos e erradicar a pobreza. O avanço do conhecimento obtido nos últimos anos e a interação entre as instituições de ensino e pesquisa assumem um papel importante na proposição e adoção de políticas públicas que visam aumentar a capacidade adaptativa da sociedade e da economia regional frente às mudanças climáticas, criando espaços de oportunidades e caminhos para a resiliência climática. Nesse sentido, a busca de soluções e oportunidades para o desenvolvimento do Semiárido brasileiro é estratégico, razão pela qual mantem-se um fórum de discussão permanente traduzido no Simpósio de Mudanças Climáticas e Desertificação no Semiárido Brasileiro, realizado bianualmente. A adoção de ações voltadas para o desenvolvimento sustentável é estratégica. A economia verde e o pagamento por serviços ambientais se tornaram oportunidades, pois atualmente o desenvolvimento econômico não pode estar dissociado das preocupações com relação às mudanças no clima e a preservação do ambiente. Para o Semiárido brasileiro é necessário fortalecer as ações em andamento e buscar soluções inovadoras para reduzir os impactos e riscos inerentes às mudanças climáticas, criar oportunidades na economia de baixo carbono e promover a inclusão social. The scientific community over the last few years has been sought solutions for sustainable development of the semiarid. The research about impacts of climate change is subsidizing mitigation and adaptation measures facing future changes, in semi-arid region. In addition, the development and adoption of processes and technologies for sustainable development, in view of economic, social and environmental sustainability are essential to increasing food security, manage water resources and eradicate poverty. The knowledge progress achieved in recent years and the interaction between education and research institutions play an important role on proposition and adopting public policies that aimed to increase the adaptive capacity of society and the regional economy to climate change, creating opportunities spaces and directions for climate resilience. In this sense, the search for solutions and opportunities for the development of the Brazilian semiarid is strategic, which is why keeping a permanent discussion forum translated at the Symposium on Climate Change and Desertification in the Brazilian semiarid carried out every two years. The adoption of actions for sustainable development, in view of economic, social and environmental viability is strategic. The green economy and payment for environmental services have become opportunities because currently the economic development cannot be dissociated from concerns about climate change. For the Brazilian semiarid is necessary to strengthen actions in progress and seek innovative solutions to reduce the impacts and risks posed by climate change, creating opportunities in the low carbon economy and promoting social inclusion. Key-words: adaptation, mitigation, environmental services, research.
