Agricultural supply chains of forest-risk commodities such as soy, palm oil, and cocoa have risen to the top of the global sustainability agenda. Demand-side actors, including consumer-goods companies, retailers, and civil society organizations have coalesced around a growing number of sustainable supply chain policies. However, despite rapid advances in tools and methods to convert data into useful information about impacts and policy effectiveness, and their implementation for decision-making is lagging. There is an urgent need to examine such demand-led action and understand how to accelerate progress towards agricultural supply chain sustainability. Here, we explore how demand-side actors within globalized supply chains see limitations in knowledge and barriers to progress in the context of forest-risk commodities. We draw from 20 semi-structured interviews and two focus group discussions with manufacturers, retailers, NGOs, and data providers. Our findings show that civil society pressure in consumer regions is perceived as a key driver guiding action, that certification is commonly sought to reduce detrimental impacts, but that collaboration to tackle systemic issues remains a gap. Companies also highlight the need for simple, timely, and meaningful metrics to assess impacts—practical usability concerns that need to be considered in the search for ever-greater accuracy in capturing complex phenomena.

The size of the world’s population has profound implications for demand for food, energy and resources, land use change and greenhouse gas emissions. This study examines why most population projections have underestimated world population growth, and the implications for actions required to achieve sustainable societies. The main determinant of future population is family size choices. Population projections by different research groups embed different assumptions about drivers of fertility decline. The common assumptions that fertility decline is driven by economic betterment, urbanisation or education levels are not well supported in historical evidence. In contrast, voluntary family planning provision and promotion achieved rapid fertility decline, even in poor, rural and illiterate communities. Projections based on education and income as drivers of fertility decline ignore the reverse causation, that lowering fertility through family planning interventions enabled economic advancement and improved women’s education access. In recent decades, support for family planning has waned, and global fertility decline has decelerated as a result. Projections calibrated across the decades of strong family planning support have not acknowledged this change and are consequently underestimating global population growth. Scenarios used to model sustainable futures have used overly optimistic population projections while inferring these outcomes will happen without targeted measures to bring them about. Unless political will is rapidly restored for voluntary family planning programs, the global population will almost certainly exceed 10 billion, rendering sustainable food security and a safe climate unachievable.

The erosion of riverbanks has a negative impact on many nations across the world, costing them land, buildings, food, fish, and other living things, which forces people to relocate. Both the frequency and severity of riverbank erosion are alarming in Bangladesh. In Zajira Upazila, a baseline investigation was carried out to evaluate the effects of river erosion on the local availability of food. The results show how erosion threatens the majority of residents in the research territory. Additionally, as a consequence of the depletion of farmland brought on by the disaster and its effects, crop production is steadily dropping. Occasionally, people lose whole properties, leaving them with few employment options and little spending power. As a result, they are always in danger of experiencing a shortage of food. The suffering people use various coping strategies to deal with these challenging circumstances, such as shifting to cheaper or less appealing eating options. Despite the fact that local governing bodies have put in place various programs to help them, including food assistance and social protection programs, these are inadequate because of the government’s constrained organizational assets and competence The study’s findings will aid scientists and decision-makers in Bangladesh and abroad in better comprehending the requirements of vulnerable riverine populations and in designing programs that would increase those societies’ food safety Therefore, these results imply that developing and implementing efficient rural development strategies could increase the food security of those residing in Bangladeshi regions threatened by riverbank erosion.

Homo sapiens has evolved to reproduce exponentially, expand geographically, and consume all available resources. For most of humanity’s evolutionary history, such expansionist tendencies have been countered by negative feedback. However, the scientific revolution and the use of fossil fuels reduced many forms of negative feedback, enabling us to realize our full potential for exponential growth. This natural capacity is being reinforced by growth-oriented neoliberal economics—nurture complements nature. Problem: the human enterprise is a ‘dissipative structure’ and sub-system of the ecosphere—it can grow and maintain itself only by consuming and dissipating available energy and resources extracted from its host system, the ecosphere, and discharging waste back into its host. The population increase from one to eight billion, and >100-fold expansion of real GWP in just two centuries on a finite planet, has thus propelled modern techno-industrial society into a state of advanced overshoot. We are consuming and polluting the biophysical basis of our own existence. Climate change is the best-known symptom of overshoot, but mainstream ‘solutions’ will actually accelerate climate disruption and worsen overshoot. Humanity is exhibiting the characteristic dynamics of a one-off population boom–bust cycle. The global economy will inevitably contract and humanity will suffer a major population ‘correction’ in this century.

Carbon neutrality is a key human endeavor to deal with global climate while China is the country producing the most publications on carbon neutrality. However, what are the focuses of carbon-neutrality research in China? To answer such an important question, this study adopts a bibliometric approach to analyze carbon-neutrality journal publications from China-based researchers during the period of 2008–2022 using CNKI and Scopus. Results showed that carbon-neutrality publications in Chinese and English journals by Chinese-based researchers increased from 4 in 2008 to 2879 in 2022. In Chinese journals, X.D. Hao was the most productive author with 10 publications. In English journals, Y.K. Zhou was the most productive author with 14 publications. As a whole, the Chinese Academy of Sciences was the most productive institution with 376 publications. Co-occurrence of keywords analysis revealed seven themes in Chinese journal articles, namely, “carbon neutrality and climate change”, “energy transformation”, “peak carbon emission”, “carbon emission and low carbon economy”, “realization path in China”, “hydrogen energy and clean energy”, and “green finance and sustainable development”. In English journals, three major clusters were formed—“carbon, carbon neutralities, emission control, and energy utilization”, “carbon dioxide, carbon neutrals, biomass, and electrocatalysts”, and “China, carbon neutrality, sustainable development, and economic development.” Most extant publications focused on policy and technological development. Emphasis shall be paid to social change and changes in people’s behavior, sectoral carbon emissions, and carbon leakage in future research.

Environmental sustainability (ES) has generally become an important topic in recent years. In this context, interest in the environmental impact of sport events has also considerably grown. However, not much is known about how people currently perceive ES in mega sport events (MSEs) and if this influences their support to stage a MSE in their home country. To shed light on this question, a survey was conducted in Germany, which resulted in a sample of 917 respondents. The data show that about one-third of them think that ES is adequately implemented in the Olympic Games and the Football World Cup. Around half of the respondents state they are in favour of hosting these events in Germany in the future and multinomial logistic regressions reveal that positive and negative perceptions of the ES of the events are important predictors of support and opposition. The same is true for the perception of the overall brand image of the event. The findings have important implications for future bidding processes because they show that the further development of ES in MSEs might have an influence on the support for hosting these events in Germany and potentially other Western democracies.

Population issues and population policies have evolved considerably between the 20th and the 21st centuries. In the 1970s, most countries confronted rapid population growth, and this situation was particularly severe in Asia. Today, on the contrary, more than half of the world population is experiencing low fertility and population aging, and several countries with very low fertility are facing the prospect of depopulation. Only one region, i.e., sub-Saharan Africa, still experiences high fertility levels. Similarly, the discussions about whether and how to intervene on population trends have also evolved over the past 70 years. Demographically focused approaches to family planning provision were dominant views in the second half of the 20th century. However, since the International Conference on Population and Development (ICPD) in Cairo in 1994, international population policy paradigms have been reframed to stress the freedom of couples and the reproductive rights of individuals. Consequently, policy interventions have favored client-focused and gender-sensitive approaches. Finally, to help chart the way forward, population policies will need to consider several key elements, broadening from a focus on support for family planning to an array of policy instruments including health, education, and culture, all of which shape future populations. This new policy framework includes the prioritization of interventions, policy consensus building, the selection of priority constituencies, the institutionalization and funding of policies, and the promotion of evidence-based and research-driven policies. In addition, in order to adapt their interventions to local contexts, population policies will need to be holistic, to promote integrated interventions, and to align with international development frameworks.

Climate change has brought significant changes to the earth and agriculture is the main economic sector that has suffered. The current study aims to assess the impact of climatic factors—measured by precipitation, temperature, and CO2 emissions—on rice production using time series from 1961 to 2019 in Malaysia. This research follows the ARDL bounds test and dynamic ARDL simulations methods to estimate long- and short-term connections of the variables under consideration. Empirical evidence indicates that long-run cointegration exist between variables. The results suggest that the sensitivity of rice production to changes in harvested area and temperature is high, while it is low for other inputs. Due to high humidity, the effect of precipitation on rice production is not significant, while temperature can reduce rice yield in the long and short term. However, the impact of carbon emissions on rice production is insignificant. Among the other determinants of rice production, the impact of agricultural labor is negative, but more area cultivation increases rice production over the long and short term. Results also show that the magnitude of the impact of the 2% increase (decrease) in temperature on rice production is greater than the changes in rainfall and carbon emissions. The results for the frequency domain causality test show that a one-way causality exists between temperature and rice production and between carbon emissions and rice production in the short and long run. Hence, the findings of this study can help policy makers to formulate appropriate adaptation methods and mitigation policies to reduce the negative effects of climate change on Malaysian rice production.

The growing interest in energy storage devices, both batteries and capacitors, could lead to the improvement of electrochemical properties such as extended charge/discharge cycles, high specific capacitance, and power density. Furthermore, the use of easily available raw materials for the production of carbon electrodes has attracted interest due to the criticality of the resources related to the current technologies of high-performance capacitors. The present article reviews carbon-based materials for supercapacitors derived from affordable coal deposits or crop waste with appropriate characteristics in terms of specific surface area, electrical conductivity, and charge/discharge stability. In addition, the substitution of organic liquids electrolytes with less dangerous solutions, such as aqueous electrolytes containing high concentrations of salt, is a valuable strategy for the design of green devices that is discussed in this review. Finally, the present article reviews the electrochemical performance of supercapacitors based on carbon electrodes obtained from various natural resources and their compatibility with safer and cheaper electrolytes.

South Africa receives insufficient rainfall to meet citizens’ water needs and this is compounded by deficiencies in infrastructure for water services because of inadequate investment and a lack of maintenance. Municipal public–private partnerships (PPPs) for water infrastructure are rarely utilised for several reasons. Central to this paper is the evaluation of the role played by various stakeholders in influencing the adoption and subsequent approval of municipal water PPP projects. This study critically examined the role of each stakeholder and how other stakeholders perceive their effectiveness during the approval process of water PPP projects. The conceptualisation and implementation of PPPs involves managing both the public and private stakeholders to achieve the desired outcomes. These diverse stakeholders have different values, anchored by the need for rent extraction (profit maximisation motive) or self-interest, as advanced by stakeholder theory. By means of structured interviews, participants highlighted the limitations of each stakeholder and how these contribute to the negative perception of future PPPs. The obtained data were triangulated with secondary sources. The findings confirmed the pursuit of self-interest by various stakeholders, impacting the pace of PPP adoption of municipal water projects.

These diverse stakeholders have different values, anchored by the need for rent extraction (profit maximisation motive) or self-interest, as advanced by stakeholder theory. By means of structured interviews, participants highlighted the limitations of each stakeholder and how these contribute to the negative perception of future PPPs. The obtained data were triangulated with secondary sources. The findings confirmed the pursuit of self-interest by various stakeholders, impacting the pace of PPP adoption of municipal water projects.","PeriodicalId":49307,"journal":{"name":"Microlithography World","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84137049","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}
