Throughout human history, people have always produced waste, but during the last century, this has shown explosive growth. Globally, a combination of rising incomes, urbanization, the development of new, cheap materials, and changing lifestyles have driven the growth of products that were designed to be used for only limited periods of time producing a totally unprecedented amount and variety of waste. However, this development has not affected all people in similar ways. Waste has been a marker of unprecedented but unbalanced efficiency, wealth and power, and conflict. Five articles address waste as a function of conflicts in areas in various places in Europe and Asia. Collectively, these papers shed an unusual light on the twentieth century world through a collection of cases, in which conflicts have tended to exacerbate challenges of waste, either by increasing the quantity of weapons and their (often toxic) remains, or by creating contexts in which the confrontation with adversaries often relegated environmental, social and health-related consideration to the backstage.

Source separation plays a pivotal role in sustainable and integrated Municipal Solid Waste Management (MSWM) and in achieving a circular economy in Asia. However, it is still not an official practice, and many cities continue to utilise open dumping, involving receiving mixed waste without pre-treatment. This paper, therefore, examines the advantages of source separation of MSW and explores the main factors for success in the planning and implementation of official source separation programmes in cities in Asia. Analysis of the results for two case studies in India and Japan could be used to strengthen capacities of policymakers in designing and implementing official source separation systems to facilitate material recovery and achieve sustainable development in Asia.

This paper investigates the nonlinear relationship between tourism and economic growth using a balanced sample of 58 countries in three continental samples (Africa, Asia, and Latin America) for the 2003–2017 period. First, we document an asymmetric threshold effect of tourism on economic growth. By utilizing an endogenous threshold regression model, we show that a single tourism threshold cutoff exists and that tourism receipts influence growth only till the threshold cutoff point in all three continental samples; however, this influence is nonexistent past the threshold point. Second, a quantile effect decomposition shows separate marginal effects for the tourism and economic growth relationship across the growth distribution. By using an unconditional quantile regression approach, we show that compared to their regional cohorts, slow- and medium-growth African countries, slow-growth Asian countries, and medium-growth Latin American countries exhibit substantially higher economic growth benefits from tourism. We explain these empirical observations and discuss their policy implications. [ABSTRACT FROM AUTHOR]

Immigrants have created better living standards by emigrating, and they also contribute to their homeland in one of two ways: by visiting as tourists or by sending remittances back home. In this paper, we examine the nexus between these two crucial channels: remittance inflows and emigrants' visits home. We model the emigrants' visits back home and show that remittances inflows per emigrant have a strong impact on emigrants' visits home. However, the relationship is mixed among different regions. For emigrants from Africa and Latin America and Asia, the remittances have a negative impact on home visits, indicating that emigrants send more money and skip visiting their homes subsequently. For emigrants from MENA, there is a significant positive impact of the remittance inflows on home visits. [ABSTRACT FROM AUTHOR]

Plastic waste circularity is a priority at a global level. Sustainable development goals (SDGs) set the ways to go, and the circular economy principles underlined the 'green' strategies to be employed. However, in practice, there is still much to do, especially in developing countries, where open burning and open dumping still represent the common way of plastic waste disposal. This review aims to analyse current plastic waste circular approaches in low-middle income settings. Seven countries were selected based on the economic level and data availability from the authors, and analysed to collect and critically discuss the actions implemented at a city level. Examples of waste minimization and recycling strategies, selective collection systems and public campaigns are reported from Africa, Asia and Latin America. First, a background analysis related to physical and governance aspects of municipal solid waste management systems of the chosen settings was conducted. The assessment was focused on the treatment processes or minimization actions. Then, the applicability of the projects to achieve the SDGs was commented on. The outcomes of the research underline the need to: (1) scale up small-scale and pilot projects, (2) disseminate good practices in more low- to middle-income settings, (3) create synergies among international partners for further replications in cities. Urgent solutions to plastic waste pollution are needed. The review presented practical actions to be implemented now to boost plastic waste circularity in developing cities. [ABSTRACT FROM AUTHOR]

Calculating the consequences of global public bads such as climate change or pandemics helps uncover the scale, distribution and structure of their economic burdens. As violent conflict affects billions of people worldwide, whether directly or indirectly, this article sets out to estimate its global macro-economic repercussions. Using a novel methodology that accounts for multiple dimensions of war, the article finds that, in the absence of violent conflict since 1970, the level of global GDP in 2014 would have been, on average, 12% higher. When disaggregating these results by conflict type, civil conflicts are estimated to have been the costliest by far. Income growth is found to be altered up to four years following the end of a conflict, although the direction of this relationship depends on the intensity and type of conflict. Countries also suffer significantly from fighting in neighbouring countries, thereby showing the importance of mitigating spillovers rapidly. The largest absolute losses associated with violence emanate from Asia, while many high-income economies are found to benefit economically from participating in conflicts on foreign soil. This analysis thus shows that, despite some evidence of a faster post-conflict growth and possible benefits for external participants, violent conflict leads to net global losses that linger long after peace is achieved, reducing the peace dividend. The article concludes by discussing public policy options to strengthen the benefits of peace as a global public good. [ABSTRACT FROM AUTHOR]
