Across the world, the COVID-19 pandemic has disrupted food supply chains and threatened food security. Singapore is highly dependent on food imports and has an open economy that exposes it to volatile global markets, so it is acutely vulnerable to the effects of the pandemic on other countries, the effectiveness of measures taken by foreign governments to combat the spread of the virus and overall disruptions of international trade links. Proactive and reactive steps have been taken to protect Singapore's food supply chains against the adverse impacts of COVID-19. In this paper, we discuss food security in the city state, the impacts of COVID-19 in the population, the local production, and imports from two main trade partners: Malaysia and China. We conclude by acknowledging the complexity of achieving food security under the very difficult circumstances.

Progress in water conservation is dependent as much on human behavior as on the promise of new technologies. Digital feedback-based interventions present an opportunity to bring these two factors together, as increasingly sophisticated technologies can help change behaviors rather than simply solving problems caused by those behaviors. This paper explores the various options and opportunities for adopting feedback-based interventions — those that communicate information for the purpose of encouraging individuals to alter water consumption habits. Lessons proposed are applicable to any realm in which individual human behavior contributes to a collective environmental or social problem. Focusing on five determinants of success (design, delivery, content, integration, and commitment), this paper presents findings of related studies and fashions them into a suite of recommendations that serves as a template for practice and agenda for future research. The underlying theme — that technology is no absolute substitute for behavioral change but can be one catalyst for it — contributes to broader discussions about the relationship between human systems and the environment.
