Climate Change Resilience

AbstractThe objective of this study was to evaluate the pathways to enhance resilience to increased climate variability and directional change among pastoral households in Simanjiro District in Northern Tanzania. The study used household survey and rainfall and temperature data. Results indicate increasing temperature and decreasing precipitation trends over the past four decades. Also, extreme climatic events, particularly drought, have become more frequent. Food and water insecurity are key factors causing an increased household vulnerability. Increased climate change-induced malaria prevalence poses additional health risks. Household adaptive strategies include livelihood diversification and migration. Local institutions are instrumental in enhancing climate change resilience at the local level. We conclude that livelihood diversification and migration are key pathways to enhancing households’ climate change resilience.

And Migration

Abstract Recent surveys of the literature on climate change and migration emphasize the important diversity of outcomes and approaches of the empirical studies. In this paper, we conduct a meta-analysis in order to investigate the role of the methodological choices of these empirical studies in finding some particular results concerning the role of climatic factors as drivers of human mobility. We code 51 papers representative of the literature in terms of methodological approaches. This results in the coding of more than 85 variables capturing the methodology of the main dimensions of the analysis at the regression level. These dimensions include authors' reputation, type of mobility, measures of mobility, type of data, context of the study, econometric methods, and last but not least measures of the climatic factors. We look at the influence of these characteristics on the probability of finding any effect of climate change, a displacement effect, an increase in immobility, and evidence in favor of a direct vs. an indirect effect. Our results highlight the role of some important methodological choices, such as the frequency of the data on mobility, the level of development, the measures of human mobility and of the climatic factors as well as the econometric methodology.

And Migration

Abstract This paper is a response Ferris (2020), specifically to the call for coalescence around a single term by which to talk about people migrating in response to climate change. While sympathetic to the imperative behind Ferris’ (2020) call, my overall argument is to reject this proposal. Instead I argue for less of focus on what we call people migrating in response to climate change, and more of a focus on how we talk about them. To justify this, I argue that a single term is inherently reductive and likely to play upon anti-immigrant sentiment due to the need to portray ‘migration as a problem’. At best this will result in a policy focus with limited capacity to address the challenge of migration in a context of climate change. At worst it will drive a policy response that is overtly counter-productive. As an alternative, I propose embracing a multitude of discourses, informed by principals that I argue will drive a humane climate agenda, and allow for a flexible approach that can account for the variety of concerns at the nexus of climate change and human migration.

North Borneo

For countries in Southeast Asia that mainly rely on surface water as their water resource, changes in weather patterns and hydrological systems due to climate change will cause severely decreased water resource availability. Warm weather triggers more water use and exacerbates the extraction of water resources, which will change the operation patterns of water usage and increase demand, resulting in water scarcity. The occurrence of prolonged drought upsets the balance between water supply and demand, significantly increasing the vulnerability of regions to damaging impacts. The objectives of this study are to identify trends and determine the impacts of extreme drought events on water levels for the major important water dams in the northern part of Borneo, and to assess the risk of water insecurity for the dams. In this context, remote sensing images are used to determine the degree of risk of water insecurity in the regions. Statistical methods are used in the analysis of daily water levels and rainfall data. The findings show that water levels in dams on the North and Northeast Coasts of Borneo are greatly affected by the extreme drought climate caused by the Northeast Monsoon, with mild to the high risk recorded in terms of water insecurity, with only two of the water dams being water-secure. This study shows how climate change has affected water availability throughout the regions.
