Plastic pollution is recognised as one of this century’s most significant environmental challenges and has the characteristics of a super wicked problem. Though researchers and governments around the globe are coming up with promising technological interventions, awareness among citizens and stringent policies are the need of the hour to tackle this issue. A few countries have issued postage stamps and postal materials showcasing the various dimensions of plastic pollution. Historically, stamps depicted every progress, problem and various milestones of humanity spanning multiple fields. We contend that the plastic pollution problems and impact should be depicted through postage stamps from all countries. Through this feat, the message of the need for sustainable usage of plastics for the common good of all species can be spread by showcasing various dimensions of the sustainability of plastic usage in postage materials. This article discusses the rise of plastic pollution, its emerging impacts, and contemporary issues and mitigation strategies through postage stamps and materials. Philately can be a medium for providing environmental awareness, considering the case of plastic pollution. It can be a strong driver to promote consciousness regarding various environmental problems among students undergoing multiple levels of education and the general public.

The Agreement on Fisheries Subsidies is designed to promote fisheries sustainability by curbing harmful subsidies that contribute to overfishing and overcapacity. However, the current approach to applying unconditional and non-negotiable special and differential treatment provisions in the Agreement is based on a North–South binary division and essentially fails to achieve the United Nations' Sustainable Development Goal 14.6. This article explores the linkage between sustainable development and a conditional right to special and differential treatment, and further presents a conditionality approach to applying appropriate and effective special and differential treatment that necessarily takes into account the diverse needs of different developing countries and better reconciles with economic, environmental, and societal sustainability. A conditionality approach shifts the basis of special and differential treatment from self-claimed ‘developing country’ status to multi-dimensions conditions embedded in the Agreement that can be objectively identified and assessed to achieve fisheries sustainability.

Ambient air pollution remains a global challenge, with adverse impacts on health and the environment. Addressing air pollution requires reliable data on pollutant concentrations, which form the foundation for interventions aimed at improving air quality. However, in many regions, including the United Kingdom, air pollution monitoring networks are characterized by spatial sparsity, heterogeneous placement, and frequent temporal data gaps, often due to issues such as power outages. We introduce a scalable data-driven supervised machine learning model framework designed to address temporal and spatial data gaps by filling missing measurements within the United Kingdom. The machine learning framework used is LightGBM, a gradient boosting algorithm based on decision trees, for efficient and scalable modeling. This approach provides a comprehensive dataset for England throughout 2018 at a 1 km2 hourly resolution. Leveraging machine learning techniques and real-world data from the sparsely distributed monitoring stations, we generate 355,827 synthetic monitoring stations across the study area. Validation was conducted to assess the model’s performance in forecasting, estimating missing locations, and capturing peak concentrations. The resulting dataset is of particular interest to a diverse range of stakeholders engaged in downstream assessments supported by outdoor air pollution concentration data for nitrogen dioxide (NO2), Ozone (O3), particulate matter with a diameter of 10 μm or less (PM10), particulate matter with a diameter of 2.5 μm or less PM2.5, and sulphur dioxide (SO2), at a higher resolution than was previously possible.

In the face of ongoing disruptions to the multilateral trade regime, from deadlock at the WTO to the rise in unilateralism, this contribution examines the role that free trade agreements (FTAs) can play in supporting the adoption of common standards for sustainable development. It does this in three moves: first, it reframes the role of FTAs from sources of obligation and mechanisms of compliance to sites of economic diplomacy where governments can shape international standards through FTA structures; second, it unpacks the relationship between regulation and standards through three case studies (dolphin-safe labelling, automotive standards, and nutrient profiling), identifying means through which FTAs can be leveraged by trade policy actors; third, it draws on these lessons to examine how FTAs can support the uptake of key new standards and quasi-standards for sustainability, in this case, the ISO Net Zero Guidelines. Finally, this contribution reflects on the implications of reappraising the development of world trade law as part of the practice of economic diplomacy.

Amidst initiatives and international agreements that call for a stronger consideration of sustainable development in international investment law, there is a need to assess whether the concept has found its way in decisions rendered by investment arbitration tribunals. References to the concept of sustainable development in investment arbitration can eventually make the adjudication of investment disputes more consistent with an increasingly important aspect of the context in which the terms of international investment agreements are embedded. Have arbitration tribunals acknowledged the relevance of the concept of sustainable development when adjudicating international investment disputes? To answer this question, this article adopts an exploratory research design and relies on a content analysis of 91 decisions that include at least one reference to the term ‘sustainable development’. It argues that the use of sustainable development by tribunals is both marginal and problematic, thus showing a strong disconnect from efforts deployed in investment policymaking and international adjudication. The article proceeds in three steps. First, it focuses on international initiatives encouraging the consideration of sustainable development in investment policymaking. Second, it briefly explores the reliance on sustainable development that has emerged in international adjudication, outside investment arbitration. Third, by analysing express references to sustainable development in international investment arbitration, it shows that these decisions demonstrate a general lack of engagement with the concept in the tribunals’ findings and a failure to fully acknowledge its integrative nature.

Food insecurity (also known as food poverty) is the inability to afford or access a healthy diet. It has become recognised as a public health emergency and is a priority in the context of the environmental, geopolitical and socio-economic implications on businesses, households and civic society. This review paper aims to discuss the merits of collecting food insecurity data and its importance in informing cross-sectoral government and others’ understanding, policymaking and action on hunger. The review paper’s key findings are that concerted action on measuring and mapping food insecurity with the aim of eliminating or reducing its prevalence represents a triple win for government, business and citizens. However, measurement does not provide solutions to food insecurity but contributes importantly to understanding its extent and severity to inform and evaluate proffered solutions. Government, business and food insecurity researchers and commentators cannot merely continue to simply describe food poverty - but must effect meaningful change amidst our communities to improve life quality in a timely way for those experiencing acute and chronic hunger. This is best done by addressing the structural causes of food insecurity through economically, socially and culturally fair and appropriate policy levers, requiring cross-sectoral collaboration. Ultimately, food insecurity requires a long-term, sustainable solution that addresses the policy issues under focus: low income, under/unemployment, rising food prices and Welfare Reform, informed by routine, Government-supported monitoring and reporting of the extent of food poverty among our citizens.

Water is essential for sustaining life and required for carrying out basic daily activities. Even though water covers the vast majority of the earth’s surface, the availability of fresh water, which is necessary to maintain human activities, is limited, making it a scarce resource. Climate change, overexploitation of groundwater, and population growth are all putting significant pressure on natural water sources, which pose a serious threat to various sectors of society, especially in agriculture. Future projections of freshwater availability indicate agriculture production will suffer a significant shock globally, including in India, leading to a threat to food security and sustainability. To ensure the sustainability of this vital resource, it is crucial to use water sensibly. Moreover, it is essential to adopt certain strategies to manage agricultural water use effectively. This includes adopting various water-efficient techniques such as ‘micro-irrigation’, ‘irrigation scheduling’, ‘conservation agriculture’, ‘crop switching’ and so on. In this review, firstly, we discuss water scarcity and its types, causes, crisis for water shortages and hindrance to sustainable development from a global perspective emphasizing the Indian scenario as a developing nation. Secondly, we elaborated our discussion on water scarcity in agriculture including the impacts of water scarcity on agricultural production and its connection to climate change, population growth, and overexploitation of natural resources globally focusing on the Indian scenario. In addition, innovative water management practices and adaptation strategies to manage agricultural water use, constraints, and the need for further research are also covered. It is anticipated that this review will benefit researchers and policymakers by providing useful information on the impacts of water limitation and adoption strategies.

Large-scale investment projects often involve contestation over competing notions of ‘development’—from promises of economic growth and integration into global value chains to perspectives that emphasise strong connections between people, territory, culture and way of life. This contestation also echoes diverse theories that have variously conceptualised development as growth, freedom, right or sustainability. This article argues that, in the face of such diversity and complexity, the notion of development that underpins international investment law tends to prioritise economic considerations. In the context of investment disputes, this can marginalise the ideas of development advanced by local actors and indigenous peoples. By connecting human rights and development in immediate terms, ongoing discussions about the right to development can provide an arena to centre ‘peoples’ as the key actor in development processes. But this normative shift would also require ensuring that the wider frameworks of international economic law recognise and provide space for plural notions of development.
