With the onset of the 17 Sustainable Development Goals (SDGs) and the Paris Agreement on climate change, the world’s nations were to create economic development integrating environmental and social improvement. However, there is still much uncertainty in the world of politics and academia as to whether these integrated goals are achievable and how they can fit best with diverse national and local contexts. Thus, there is always a need to find nations that can show how it can be achieved in different settings shaped by local experiences, challenges, and opportunities. Bhutan could be one of these nations as it could be argued that it has, to an extent, simplified the task to fit its values and aspirations. Bhutan has three major goals that need to be integrated: Wealth (GDP) to align with their middle-income aspiration, thus providing opportunities for employment, Greenhouse Gas emissions (GHG) that are maintained at a carbon neutral level, which is beyond most national commitments, and Bhutan’s renowned Gross National Happiness (GNH) index, which covers their socio-economic goals. We show this integration and then synthesize some core findings from a literature review on the theory and practice of sustainable development through the lens of the three integrated goals of Bhutan, thereby placing the case of Bhutan into the wider literature. This paper seeks to show how one emerging nation can model an operational sustainability policy. The paper highlights some plausible synergies between the 17 SDGs and the domains and indicators of GNH that could help nations struggling with how they can create sensible sustainability outcomes from these new global agendas. Bhutan has framed the GNH as its contribution to sustainability. However, this paper suggests that it may be the integration of the GNH with GDP and GHG that is its real contribution. Furthermore, Bhutan’s 3G model of fully integrating GNH, GDP, and GHG suggests a way forward for achieving their imperatives of economic growth, whilst enabling the SDGs and achieving the difficult climate change goal. It may also suggest a model for other nations wanting to find a complementary way of framing economic growth, the 17 SDGs, and the Paris Agreement into a coherent set of policies.

This paper examines the integration of sustainability principles into architectural education programs at South Korean Universities that have been accredited by the Korea Architectural Accrediting Board (KAAB). Accreditation requires the successful implementation of 30 so-called Student Performance Criteria (SPCs). Similar to recent improvements to international architectural education, different principles of sustainability have been successfully implemented by the KAAB. This paper identifies eight sustainability-related SPCs that can be utilized to teach sustainability. The analysis of 48 accredited five-year architectural education program curricula in South Korea has revealed which sustainability-related SPCs are addressed each semester. Furthermore, the average number of credits per sustainability-related SPC in different course types, such as theory courses and design studios, has been identified. Theory courses with an emphasis on sustainability education have been defined as sustainability core courses. The results reveal that a majority of existing programs primarily address environmental aspects of sustainability. Furthermore, a sequential course structure analysis elucidates three main curriculum types, with different potential for integrated sustainability education in sustainability core courses and design studios: (i) sustainability core course preceding (high potential); (ii) sustainability core courses and design studio, accompanying (high potential); and (iii) sustainability core course following (low potential).

Integrating freight and public transport infrastructure can lead to providing economic feasibility to public transportation systems and reducing externalities related to urban freight transport. This can be achieved by sharing the infrastructure of freight and public transportation systems. Additionally, failed deliveries represent a major challenge in e-commerce. Lockers can address this problem and promote sustainable urban freight transport. This paper identified a locker network in a public transportation infrastructure. The framework considered scenarios built under the 15-min city concept, and the analysis is based on a case study in Jaraguá do Sul (Brazil, a mid-sized Brazilian city, and its conurbated area. The networks were found by solving a p-median problem, which minimised the maximum distance between the lockers and the population. The findings showed that, in the best scenario with 16 lockers, the population could reach the lockers within a 10-min cycling ride. Additionally, the results showed that the public transportation network provides a locker network to integrate freight and public transportation. The locker network is accessible to public transportation and micromobility users. With this solution, residents play an active role in last-mile deliveries. In addition, lockers can work as mini hubs for crowdshipping services. In addition to reducing urban delivery trips, this solution can encourage public transportation usage, which contributes to more sustainable cities.

Sustainability of transport infrastructure integration begins with involving an all-inclusive transportation chain instead of only focusing on one part of the journey. This is achieved by facilitating spatial integration between diverse transport modalities to allow for a multiplicity of travel opportunities. This paper unpacks the extent of the spatial integration of non-motorized transport and urban public transport infrastructure within the city of Johannesburg in South Africa. Cycling activity datasets derived from Strava Metro and the spatial data of urban public transport infrastructures were collected to demonstrate existing spatial patterns and infrastructure connectivity. Exploratory spatial data analysis and focal statistics analysis were central in the data processing. The findings reveal that cycling activities are separated from urban public transport infrastructure, and the city of Johannesburg’s transport system is characterized by spatially fragmented commuting and cycling operations, with limited to no sharing of infrastructure. Most public transport stations are not easily accessible for non-motorized transport and are characterized by inadequate cycling facilities. In conclusion, the identification of an urban public transportation catchment area becomes essential for developing cities such as Johannesburg. This can be used as tool for planning infrastructural upgrades and forecasting potential public transport ridership while also assessing the impacts of investments in transit planning. There is thus a need to integrate motorized urban public transport and cycling infrastructural developments toward promoting multi-mobility and infrastructure sharing.

The Mar del Plata International Water Conference provided the first global assessment of the water sector. It was found that in most developing countries the state of water supply and sanitation services were deplorable. Consequently, a call for concerted action to improve coverage and efficiency of the water supply and sanitation sector was launched. This call resulted in the International Water Supply and Sanitation Decade (1981–1990). The Decade provided important lessons concerning effective methodologies to improve the state of the WSS sector. The paper discusses why the poor state of the water supply and sanitation conditions still tend to be the greatest development failure during the 20th century. The recipe for success was there, and the money was there. So, why were governments and big donors like the World Bank refusing to apply the lessons from the Decade? The basic conditions for success are spelled out, and some successful cases are used to illustrate these. The conclusion is that change is possible but that civil society organizations have to be empowered to make governments "feel the heat" and spend more money on water and sanitation, and to spend it more wisely.
