Manufacturing urbanism: Improvising the urban–industrial nexus through Chinese economic zones in Africa

The relationship between industrialisation and urban development is subject to assumptions based on experiences in the global North, with little research on how it plays out in countries undergoing urbanisation and industrialisation today. In the context of recent excitement about China’s role in stimulating an ‘industrial revolution’ in Africa, we examine how Chinese zones in Ethiopia and Uganda are influencing the urban–industrial nexus. We argue that Chinese zones are key sites of urban–industrial encounter, but these dynamics are not primarily driven by the government officials that dominate the ‘policy mobilities’ literature, nor by the State-Owned Enterprises usually associated with Chinese activity overseas. Rather, they are emerging through the activities of inexperienced private Chinese actors who do not even operate in the worlds of urban policy. Faced with government histories and capacities that vastly differ from China’s, directly replicating the Chinese experience is virtually impossible; yet the tentative and improvisational relationships between Chinese firms, African government authorities and other local actors are gradually moulding new urbanisms into shape. The piecemeal bargaining and negotiation that unfolds through these relationships bridges some of the gaps between industrialisation and planning, but this cannot compensate for the governance of the urban–industrial nexus at higher scales

As a result several aspects of water planning for 350 new homes and 8000 m2 of workspace needed to be considered before any infrastructure investment was undertaken. This included assessment of the future capacity requirements (i.e. inflows and outflows) for water infrastructure (i.e. mains water supply, wastewater disposal, rainwater storage and stormwater disposal) much of which will be located underground. This paper looks at the implications of various water management strategies on the Luneside East site (e.g. water-efficient appliances, greywater recycling and rainwater harvesting) in line with current policy measures that focus on technology changes alone (e.g. the code for sustainable homes). Based on these findings this paper outlines some basic implications for technological resilience discussed in the context of four ‘world views’ – that is, the urban futures scenarios considered in this special issue. Conclusions are drawn as to how far this can take engineers, planners and developers in understanding and planning for resilient water infrastructure within a development like Luneside East

Assessment of coronary artery disease and calcified coronary plaque burden by computed tomography in patients with and without diabetes mellitus

Purpose: To compare the coronary atherosclerotic burden in patients with and without type-2 diabetes using CT Coronary Angiography (CTCA). Methods and Materials: 147 diabetic (mean age: 65 ± 10 years; male: 89) and 979 nondiabetic patients (mean age: 61 ± 13 years; male: 567) without a history of coronary artery disease (CAD) underwent CTCA. The per-patient number of diseased coronary segments was determined and each diseased segment was classified as showing obstructive lesion (luminal narrowing >50%) or not. Coronary calcium scoring (CCS) was assessed too. Results: Diabetics showed a higher number of diseased segments (4.1 ± 4.2 vs. 2.1 ± 3.0; p 400 (p < 0.001), obstructive CAD (37% vs. 18% of patients; p < 0.0001), and fewer normal coronary arteries (20% vs. 42%; p < 0.0001), as compared to nondiabetics. The percentage of patients with obstructive CAD paralleled increasing CCS in both groups. Diabetics with CCS ≤ 10 had a higher prevalence of coronary plaque (39.6% vs. 24.5%, p = 0.003) and obstructive CAD (12.5% vs. 3.8%, p = 0.01). Among patients with CCS ≤ 10 all diabetics with obstructive CAD had a zero CCS and one patient was asymptomatic. Conclusions: Diabetes was associated with higher coronary plaque burden. The present study demonstrates that the absence of coronary calcification does not exclude obstructive CAD especially in diabetics

Global commitment towards sustainable energy

Energy is crucial to economic and social development and improves quality of life. However, fossil fuel energy produces greenhouse gases (GHGs) and cannot be sustained for a long time. It is essential to tackle these problems by moving towards renewable and sustainable energy. Some countries, including those in the Arabian Gulf region, are still in the appraisal stage of adopting different forms of renewable energy. This paper reviews the business potential and likely GHG reductions associated with adopting renewable energy in Oman. It is revealed that 1·9 Mt of annual carbon dioxide emissions could be cut by producing 10% of the country’s electricity from renewables. The paper further discusses the global sustainable energy commitment under the UN Framework Convention on Climate Change and reviews the 2030 targets of some countries that are high producers of GHGs. It is anticipated that if all these planned targets are achieved, the total sustainable energy contribution could grow by nearly 11 000 TWh by 2030. These plans provide guidance for those countries still preparing to submit their plans to the UN

Challenges towards renewable energy : an exploratory study from the Arabian Gulf region

Considering the importance of energy for social and economic development, access to clean, affordable and reliable energy has been adopted as one of the United Nations sustainable development goals that all countries aim to achieve by 2030. However, much of the world's energy is still produced from fossil fuels and thus the progress towards clean and renewable energy is slow. This paper explores the key challenges towards renewable energy in Gulf Cooperation Council countries blessed with plenty of oil and gas reserves. The key challenges identified through literature review were ranked using a quantitative approach through the data collected from a selective sample across the six countries. These challenges in order of importance were found to be policies and regulations, manpower experience and competencies, renewable energy education, public awareness, costs and incentives for renewable energy and government commitment. The findings could be helpful to decision makers and government organisations in the region to develop strategies to overcome these identified challenges

Health sector recovery in early post-conflict environments: experience from southern Sudan

Health sector recovery in post‐conflict settings presents an opportunity for reform: analysis of policy processes can provide useful lessons.1 The case of southern Sudan is assessed through interviews, a literature review, and by drawing on the experience of former technical advisers to the Ministry of Health. In the immediate post‐conflict phase, the health system in southern Sudan was characterised by fragmentation, low coverage of health services, dismal health outcomes and limited government capacity. Health policy was extensively shaped by the interplay of context, actors and processes: the World Bank and the World Health Organization became the primary drivers of policy change. Lessons learned from the southern Sudan case include the need for: sustained investment in assessment and planning of recovery activities; building of procurement capacity early in the recovery process; support for funding instruments that can disburse resources rapidly; and streamlining the governance structures and procedures adopted by health recovery financing mechanisms and adapting them to the local context
