Climate Insecurity in (Post)Conflict Areas: The Biopolitics of United Nations Vulnerability Assessments

Within the United Nations, the United Nations Development Programme, United Nations Environment Programme and Office for the Coordination of Humanitarian Affairs have all highlighted climate risks as relevant to their work in areas affected by conflict, endorsing human security approaches as valid for mapping the relationships between climate stresses and conflict-related harm. While this policy interest has limited operational presence, I discuss salient assessments of climate vulnerability in (post)conflict areas, arguing that these agencies have applied a natural disaster rather than conflict regulation inflection of humanitarian reason. The former entails a biopolitical paradigm of disaster risk reduction, prescribing technical-managerial measures to build the resilience of vulnerable populations. This framing supports a depoliticised stance reflecting UN norms of neutrality and impartiality. I claim that this position nevertheless disregards its own geopolitical conditions and effects, which dilute the scope for international humanitarian law to assign responsibility for conflict-related harm.     

Agriculture and climate change in global scenarios: why don't the models agree

Agriculture is unique among economic sectors in the nature of impacts from climate change. The production activity that transforms inputs into agricultural outputs involves direct use of weather inputs (temperature, solar radiation available to the plant, and precipitation). Previous studies of the impacts of climate change on agriculture have reported substantial differences in outcomes such as prices, production, and trade arising from differences in model inputs and model specification. This article presents climate change results and underlying determinants from a model comparison exercise with 10 of the leading global economic models that include significant representation of agriculture. By harmonizing key drivers that include climate change effects, differences in model outcomes were reduced. The particular choice of climate change drivers for this comparison activity results in large and negative productivity effects. All models respond with higher prices. Producer behavior differs by model with some emphasizing area response and others yield response. Demand response is least important. The differences reflect both differences in model specification and perspectives on the future. The results from this study highlight the need to more fully compare the deep model parameters, to generate a call for a combination of econometric and validation studies to narrow the degree of uncertainty and variability in these parameters and to move to Monte Carlo type simulations to better map the contours of economic uncertainty.     

Are CEOs expected utility maximizers?

Are individuals expected utility maximizers? This question represents much more than academic curiosity. In a normative sense, at stake are the fundamental underpinnings of the bulk of the last half-century’s models of choice under uncertainty. From a positive perspective, the ubiquitous use of benefit-cost analysis across government agencies renders the expected utility maximization paradigm literally the only game in town. In this study, we advance the literature by exploring CEO’s preferences over small probability, high loss lotteries. Using undergraduate students as our experimental control group, we find that both our CEO and student subject pools exhibit frequent and large departures from expected utility theory. In addition, as the extreme payoffs become more likely CEOs exhibit greater aversion to risk. Our results suggest that use of the expected utility paradigm in decision making substantially underestimates society’s willingness to pay to reduce risk in small probability, high loss events.     

Web-based social movements contesting marketing strategy: The mobilisation of multiple actors and rhetorical strategies

Abstract

Previous studies suggest that marketing strategy is developed and used to mobilise and configure the actions of firm actors, creating a set of stabilising activities focused on the firm–customer dyad. Destabilising forces precipitated by the Internet and associated digital technologies involving contention and disruption by multiple actors are much less prevalent in the marketing literature. The central point we advance is that rather than marketing strategy being a controlled and stabilising force for firms in their relationships with customers, it can often lead to socially produced spaces where consumers and, importantly, other multiple actors form a social movement to actively attempt to destabilise it and contest its legitimacy. Using an innovative research approach, the findings of this study show how social movements proactively enrol and mobilise a wide range of relevant actors into a network of influence. Critical to this are rhetorical strategies, acting as important levers in attempts to destabilise and delegitimise a dominant firm’s marketing strategy.     

Soil and cropping system research in semi-arid West Africa as related to the potential for conservation agriculture

Semi-arid West Africa faces challenges to increase sorghum and pearl millet production to meet food needs for a growing human population while increasing soil carbon (C), nutrient levels, and water holding capacity that are documented benefits of conservation agriculture. This review focuses on the wealth of research on cropping systems, tillage, crop residue, nutrient, and weed management as related to conservation agriculture. It also identifies needs for multidisciplinary, integrative research to assist the transition from current production systems to conservation agriculture. Crop residue use as livestock feed, or fuel are major constraints to adoption of conservation agriculture, which could be reduced by wood production in agroforestry systems, alternate energy sources, and increased forage supply. Crop residue and grain yields are related, thus improved crop, soil, water, nutrient, and weed management to increase grain yield would also increase the supply of crop residue with potential for ‘left over’ crop residue being available for soil mulching. Incorporating indigenous shrubs and/or cover crops could also increase crop residue supply. Species diversity can be increased through crop rotation, agroforestry, cover crops, and intercrops. Higher grain and stover yields and increased profit potential for resource-poor farmers in West Africa will be required before wide-scale adoption of conservation agriculture will be possible.
