Tiger atmospheres and co-belonging in mangrove worlds

Abstract: This article adopts a place-based approach to explore tiger atmospheres in the Sundarbans, a transboundary environmental commons and major climatic hotspot in the Ganges-Brahmaputra-Meghna delta of India and Bangladesh. We argue that affective intensities of greed (lobh), fear (bhaya), respect (srodhya), trust (biswas) and empathy (karuna) sensed by the tiger subject contribute to novel theoretical as well as empirical insights into co-belonging and intersectional multispecies justice. We explore these animal atmospheres through multi-sited ethnographic research that include embodied observations, photographs, 31 in-depth interviews and focus groups with impoverished as well as racialised low-caste Hindus (Dalits/Scheduled Castes), Adivasis (Indigenous peoples) and Muslim forest-dwellers in India and Bangladesh. This attention to more-than-human geographies, animal atmospheres and subaltern stories situated in the Bengal delta unsettles macro-narratives of forest conservation and wildlife management that reduce animals to passive subjects or alternatively make them killable.

Economic Valuation with State-Preference Techniques: A Manual

Abstract: Part 1 The foundations of economic valuation: the uses of economic valuation the nature of economic valuation and economic efficiency economic valuation and other values economic valuation when there are no markets economic valuation and the demand curve willingness to pay and willingness to accept total economic value and aggregation total economic value aggregating across individuals - stakeholder analysis aggregating across individuals - distributional adjustments aggregation over time stated preferences and public participation. Part 2 Commissioning a stated preference study: defining the context is economic valuation necessary and credible? what alternative and appropriate procedures are available? how credible will the results be? the cost of the study "mixed" valuation and non-valuation approaches choosing between economic valuation techniques use and non-use values attributes and total values hard versus soft data contexts where given techniques cannot be applied other considerations commissioning a valuation study - a checklist social goals and CBA the required level of accuracy the issue of "standing" issues with stated preference techniques using expert advice assessing the consultants a typical workplan for a stated preference study. Part 3 Population, sample and survey mode: defining the target population the need for and the importance of sampling the sampling frame choosing the sample non-probabilistic design probabilistic design choosing the survey mode choosing the sample size. Part 4 Designing a contingent valuation questionnaire: useful lessons from other disciplines the stages of designing a CV questionnaire what is the policy change being valued? constructing the valuation scenario eliciting monetary values debriefing and follow-up questions attitudes, opinions, knowledge and uses demographics questionnaire structure pre-testing the main survey. Part 5 Contingent valuation - analyzing the results: contingent valuation data sets data on WTP missing data on WTP data on determinants of WTP missing data on household characteristics specification of the bid function the theoretical model the analyst's model -the utility difference approach the analyst's model - the bid function approach which are better - utility difference models or bid function models? estimating mean and median WTP models for testing the validity of WTP values models for benefits transfer exercises conclusions. Part 6 Designing a choice modelling questionnaire: what is choice modelling? main CM approaches choice experiments contingent ranking contingent rating paired comparisons common design stages selection of attributes assignment of levels choice of experimental design construction of choice sets measurement of preferences advantages and disadvantages of choice experiments relative to other economic valuation techniques advantages disadvantages do choice modelling approaches solve a

Estimating the economic benefits of a Wetland restoration program in New Zealand: A contingent valuation approach

Abstract: Decades of failure to evaluate the ecosystem services provided by Pekapeka Swamp in New Zealand led to decisions that allowed prolonged degradation of the swamp, resulting in the loss of potential economic value. In 1998 a long term management plan was adopted to restore and preserve the swamp without evaluating the potential welfare benefits of the plan. This study contributes to literature by providing the first estimation of total economic value (TEV) of the restoration and preservation of Pekapeka Swamp. Using the contingent valuation method, this study shows that estimated TEV ranges from NZ$1.64 million to NZ$ 3.78 million per year and the net present value ranges between NZ$5.05 million and NZ$16.39 million. These results imply that the restoration and preservation of Pekapeka Swamp is an important investment.

Envisioning the future of cooperation on common rivers in South Asia: a cooperative security approach by Bangladesh and India to the Tipaimukh Dam

Abstract: Using the historical trends in Bangladesh–India water disputes as a background, this article argues that if Bangladesh and India approach the proposed Tipaimukh Dam on the trans-boundary Barak River from a cooperative security angle, they will be successful in making a significant deviation from the sovereignty-based approach that has been a prevailing feature of negotiations on water issues in South Asia. By emphasizing the benefit from a ‘share the resources’ model, as opposed to a ‘divide the resources’ model, such an approach will be mutually beneficial and may have significant ‘spill-over’ repercussions for multilateral cooperation on rivers in South Asia.
