From conflict to resilience? Explaining recent changes in climate security discourse and practice

The recent rise of resilience thinking in climate security discourse and practice is examined and explained. Using the paradigmatic case of the United Kingdom, practitioners’ understandings of resilience are considered to show how these actors use a resilience lens to rearticulate earlier storylines of climate conflict in terms of complexity, decentralisation, and empowerment. Practitioners in the climate security field tend to reinterpret resilience in line with their established routines. As a result, climate resilience storylines and practices turn out to be much more diverse and messy than is suggested in the conceptual literature. Building on these findings, the recent success of resilience thinking in climate security discourse is explained. Climate resilience – not despite but due to its messiness – is able to bring together a wide range of actors, traditionally standing at opposite ends of the climate security debate. Through resilience storylines, climate security discourse becomes something to which a wide range of actors, ranging from security to the development field, can relate.

Comparative assessment of vulnerability of smallholder livestock farmers to climate change in North-West Ghana

ABSTRACT

This study examined the vulnerability of smallholder livestock farmers in North-West Ghana to climate change using data obtained from 200 livestock farmers obtained through the administration of a semi-structured questionnaire. The Livelihood Vulnerability Index (LVI) approach was used to examine the levels of vulnerability. The study compared the vulnerability between the Nandom district and the Lawra district. The empirical results revealed that livestock farmers are more vulnerable to climatic extremes in the Nandom district than the Lawra district. The study highlights the critical role of the government regarding education and construction of water resources, among others.     

Agricultural productivity and environmental insecurity in the Usangu plain, Tanzania: policy implications for sustainability of agriculture

Sustainable agricultural development is a necessity for sustainable economic growth and social development in Africa. Sustainable agriculture largely depends on how effective natural and environmental resources are managed and utilized; it also depends on the security of continuous access to such resources. This research was aimed to look into trends in agricultural productivity, examine the persistence of the environmental insecurity, analyze the relationship between the two, and explore their links to the national development policies. The results are discussed in the context of relevance to national development policies and their implications on the sustainability of agriculture and rural livelihoods security. Literature survey, records collection from the stakeholders, village level participatory assessments (PAs), observations and questionnaire survey were tools used for data collection. The study shows significant (P < 0.01) declines in cereal crop yields, cattle milk yield and cattle calving rate, and increasing cattle mortality rate. Elements of environmental insecurity were found to account for decline in agricultural productivity; significant (P < 0.01) proportion (68%), of 266 households interviewed, reported land resources deterioration, declining soil fertility, and increasing drought frequencies as the causes of their low productivity. Declined fertilizer consumption and increasing variability in rainfall amount significantly (P < 0.01) accounted for 59% and 39%, respectively, of the variations observed in total annual production of rice and maize, which are major cereals in the study area. This study recommends measures to improve soil productivity such as improved fertilizer application and use of organic manures along with mineral fertilizers for maintaining soil productivity; education of farmers on sustainable use and management of land resources; and pro-poor rural policies in agricultural development and environmental governance.

Realising a resilient and sustainable built environment: towards a strategic agenda for the United Kingdom

Recent natural and human-induced emergencies have highlighted the vulnerability of the built environment. Although most emergency events are not entirely unexpected, and the effects can be mitigated, emergency managers in the United Kingdom have not played a sufficiently proactive role in the mitigation of such events. If a resilient and sustainable built environment is to be achieved, emergency management should be more proactive and receive greater input from the stakeholders responsible for the planning, design, construction and operation of the built environment. This paper highlights the need for emergency management to take a more systematic approach to hazard mitigation by integrating more with professions from the construction sector. In particular, design changes may have to be considered, critical infrastructures must be protected, planning policies should be reviewed, and resilient and sustainable agendas adopted by all stakeholders.

Testing the limits of social resilience in ant colonies

Social resilience is the ability of Leptothorax ant colonies to re-assemble after dissociation, as caused, for example, by an emigration to a new nest site. Through social resilience individual workers re-adopt their spatial positions relative to one another and resume their tasks without any time being wasted in worker respecialisation. Social resilience can explain how an efficient division of labour can be maintained throughout the trials and tribulations of colony ontogeny including the, often substantial, period after the queen dies when the ability to conserve worker social relationships may be essential for efficiency to be maintained. The mechanism underlying social resilience is, therefore, expected to be robust even in the absence of many of the colony’s components, such as the queen, the brood and even a large proportion of the workers. Such losses are likely, given the ecology of this genus. Using sociotomy experiments, we found that social resilience can occur in the absence of the queen. Furthermore, the spatial component of social resilience can occur even when the queen, the brood, as well as a large proportion of the workers, are all absent simultaneously and hence many of the tasks are missing. We conclude, therefore, that social resilience is indeed robust. This does not, however, preclude worker flexibility in response to changes in task supply and demand. We propose a possible sorting mechanism based on worker mobility levels which might explain the robustness underlying this phenomenon. Received: 25 October 1999 / Accepted: 1 April 2000     

Building disaster resilience using social messaging networks: the WeChat community in Houston,Texas, during Hurricane Harvey

Analyses of disaster resilience have focused increasingly on the role of social capital and online social networks in recovery. This study complements this field of work by investigating three key issues. First, it examines how a social messaging application, WeChat, helped individuals to access and to mobilise three types of social capital—bonding, bridging, and linking—during Hurricane Harvey, a Category 4 storm that made landfall in Louisiana and Texas in the United States in August 2017, resulting in significant flooding and loss of life. Second, it pinpoints and assesses quantitatively how individuals' WeChat group usage and social capital influenced their post-disaster well-being. Third, it demonstrates how a minority and immigrant community in Houston, Texas, overcame the disadvantages commonly observed in other disaster research through the utilisation of social media. The findings of this study should aid governmental and community efforts to foster resilience in the face of natural and human-induced hazards.     

Remaking the world in our own image: vulnerability,resilience and adaptation as historical discourses

A warming climate and less predictable weather patterns, as well as an expanding urban infrastructure susceptible to geophysical hazards, make the world an increasingly dangerous place, even for those living in high‐income countries. It is an opportune moment, therefore, from the vantage point of the second decade of the twenty‐first century, to review the terms and concepts that have been employed regularly over the past 50 years to assess risk and to measure people's exposure to such events in the light of the wider geopolitical context. In particular, it is useful to examine ‘vulnerability’, ‘resilience’, and ‘adaptation’, the principal theoretical concepts that, from an historical perspective, have dominated disaster studies since the end of the Second World War. In addition, it is valuable to enquire as to the extent to which such discourses were ideological products of their time, which sought to explain societies and their environments from the stance of competing conceptual frameworks.
