The scope and scale of the informal food economy of South African urban residential townships: Results of a small-area micro-enterprise census

Growing urbanisation in South Africa is reflected in burgeoning Working class and informal township settlements on the fringes of its major towns and cities. Paired with this is an increasing reliance on cash as the primary means of economic transaction, which has in turn stimulated the growth of micro-enterprise business activities within the township context. This article discusses the findings of an eight-township small-area census which occurred between 2010 and 2013 in Cape Town, Johannesburg, Ekurhuleni and Durban townships representing 250 000 residents. The researchers were able to establish the scope and scale of informal food and drink retailing in these localities. Of the 10 049 micro-enterprises located in the study, some 3966 (or 39% of the total) trade in food. These include enterprises in primary production, fresh produce retailing, grocery retailing from house and spaza shops, and informal foodservice enterprises. Food is the basis for much township informal business and plays an important role in making food increasingly affordable and locally accessible, and in creating cash employment. The article builds on the knowledge base of the township informal economy role in bolstering food security needs for the marginalised.

COVID-19 and business renewal: Lessons and insights from the global airline industry

The emergence of the COVID-19 pandemic has adversely affected the fortunes of multiple companies around the globe. Accordingly, questions are increasingly being asked about how organizations can revitalize during and after a crisis. Yet, we have limited understanding of how organizations renew themselves during crises over time. We explore this question through the lens and examination of two South-Asian airlines: Pakistan International Airlines and Sri Lankan Airlines. The cases offer important insights into the reasons behind underperformance of state-controlled enterprises and renewal activities. We shed light on strategic renewal (SR) in the wake of increasing liberalization and deregulations in the global airline industry. To this end, we propose a four-stage approach towards renewing such underperforming organizations to respond effectively to black swan events and external shocks.     

环境质量因地方政府的重视得到改善吗? ——基于文本挖掘的经验分析

本文利用Python技术对地方政府工作报告进行深度挖掘,在测度地方政府环境重视度的基础上研究地区环境质量是否因政府对环境问题的重视得到改善.实证结果显示,地方政府对环境问题的重视的确带来环境质量的显著改善.进一步的机制分析发现,地方政府的环境重视度之所以能带来环境质量改善,源于在一系列约束条件下地方政府选择具有显著治污绩效的环境立法和排污税费两个治理工具.一方面,证实地方政府重视对中国环境问题的解决非常重要,实现绿色、协调和可持续发展需地方政府提高对环境问题的重视;另一方面,通过地方政府在治理工具上的选择偏好发现当前环境治理实践中的"短板"和问题,为地区环保事业的发展提供有益的改进方向.
