A Policy Maker’s Guide to Designing Payments for Ecosystem Services

Over the past five years, there has been increasing interest around the globe in payment schemes for the provision of ecosystem services, such as water purification, carbon sequestration, flood control, etc. Written for an Asian Development Bank project in China, this report provides a user-friendly guide to designing payments for the provision of ecosystem services. Part I explains the different types of ecosystem services, different ways of assessing their value, and why they are traditionally under-protected by law and policy. This is followed by an analysis of when payments for services are a preferable approach to other policy instruments. Part II explains the design issues underlying payments for services. These include identification of the service as well as potential buyers and sellers, the level of service needed, payment timing, payment type, and risk allocation. Part II contains a detailed analysis of the different types of payment mechanisms, ranging from general subsidy and certification to mitigation and offset payments. Part III explores the challenges to designing a payment scheme. These include the ability to monitor service provision, secure property rights, perverse incentives, supporting institutions, and poverty alleviation

Strategies for the construction of cassava brown streak disease viral infectious clones

Cassava brown streak disease (CBSD) has major impacts on yield and quality of the tuberous roots of cassava in Eastern and Central Arica. At least two Potyviridae species cause the disease: Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV). Cloned viral genome sequences known as infectious clones (ICs) have been important in the study of other viruses, both as a means of standardising infectious material and characterising viral gene function. IC construction is often technically challenging for Potyviridae due to sequence instability in E. coli. Here, we evaluate three methods for the construction of infectious clones for CBSD. Whilst a simple IC for in vitro transcription was made for UCBSV isolate ‘Kikombe’, such an approach failed to deliver full-length clones for CBSV isolates ‘Nampula’ or ‘Tanza’, necessitating more complex approaches for their construction. The ICs successfully generated symptomatic infection in the model host N. benthamiana and in the natural host cassava. This shows that whilst generating ICs for CBSV is still a technical challenge, a structured approach, evaluating both in vitro and in planta transcription systems should successfully deliver ICs, allowing further study into the symptomology and virulence factors in this important disease complex

International Influences and Drag: Just a Case of Tucking or Binding?

Recently there has been an  internationalisation in the training of UK drag performers. Whilst papers exist focused on drag kings and queens related to their community, few explore how kings/queens train – and fewer still explore international aspects. There are formal courses for drag, but historically this training was informal, present within specific performance communities built around LGBTQ cultures. Tracing dominant figures in such training – the drag mother/father – in order to historicise and contextualise the current explosion in drag performance,the paper argues that the potential globalisation of drag is largely down to the diversification of sources of knowledge available via the internet. Traditionally, performers trained with an established practitioner, where regional variances of drag were passed on. However, current new performers often learn ‘tricks of the trade’ through internet videos posted by people on other continents. In these videos, practitioners pass on their knowledge from the perspective of their locality, as if universal. New kings/queens are not passive in this training and locally infuse their acts, yet historical and local erasures persist. The paper argues that to engage with drag as performance one must be aware of locality and the deep connects drag has with its communities

The figure of the refugee in Hassan Blasim’s “The Reality and the Record”

This article considers Hassan Blasim’s short story, “The Reality and the Record”. It argues that Blasim’s asylum seeker should be read as a powerful challenge to extant responses to the ever-growing global refugee crisis: a vision of the many difficulties faced by twenty-first-century displaced persons, no longer confined to the refugee camps of the mid-twentieth century most often associated with Palestinian literature in the Middle East, but seeking elusive shelter in Europe. I argue that Blasim’s short story highlights the impossibility of the demands placed upon those seeking shelter in the developed world, reminding us of the under-recognized role of trauma, narrative, agency, and especially evidence in seeking humanitarian asylum. By undermining any confidence we might have in an idealized “truth”, the text questions the morality of asylum-seeking processes in the developed world, demanding that its readers reevaluate their own stance in relation to displaced persons, and asserting that the burden of narrating oneself into a place of safety, of performing worthy victimhood, is neither just, nor feasible
