Participatory justice and climate adaptation for water management in Small Island Developing States: a systematic literature review and discussion

Latest Results

Abstract

As the impacts of climate change increase, Small Island Developing States (SIDS) in particular shall face increasingly significant adaptation challenges. Past climate adaptation efforts within SIDS have had limited success. As such, the purpose of this systematic literature review has been to identify areas of importance for facilitating climate adaptation, particularly within Small Island Developing States (SIDS), and more specifically, to assess the extent to which participatory justice within decision-making processes is recognised as an important component of climate adaptation through the lens of water management. This review process utilised the SPIDER tool to guide the literature search across SCOPUS, Web of Science and EBSCO host databases, generating 495 publications that were reduced to a total of 70 sources guided by PRISMA, informing the review’s results and discussion. Thematic analysis of the selected studies was applied, utilising the Values-Rules-Knowledge framework. Through this analysis, five principles were created and comprise the major conclusions of this review: (1) ensuring community engagement, (2) expanding available options through local experimentation, (3) ensuring that monitoring and evaluation of adaptation initiatives are taken seriously, (4) adopting decision-making mechanisms that are systems-oriented and inclusive, and (5) investing only if there is a long-term commitment to protecting SIDS. It is hoped that these principles can serve as a comprehensive guide for funding agencies, applied projects and research aiding climate adaptation within SIDS.

SWAT based analysis of multiple GCM models for predicting the long-term effects on various hydrometeorological components of a dam-to-dam river basin

Latest Results

Abstract

This study explored how the water balance components of the Middle Tapi Basin (MTB) might alter between 2010 and 2100 as an outcome of climate change. We used an approach were Statistically downscaled future predicted data for temperature and rainfall for five different Global circulation models were employed under two Representative Concentration Pathways (RCP 4.5 and RCP 8.5). The baseline and future scenarios’ monthly analyses of multiple water balance indicators also showed that RCP 4.5 and RCP 8.5 will see an increase in maximum temperature of 5.2% and 9.5%, respectively, by the end of the century. The baseline period contribution from monsoonal rainfall and streamflow was also 89.3% and 90.6%, but in future scenarios, the figures are likely to reduce to 75.2% and 57.8% for RCP 4.5 and 70.8% and 54.7% for RCP 8.5. While the average inflow estimates at the Ukai dam tend to rise by 19.2% and 46.8% till the distant future scenario for RCP 4.5 and RCP 8.5, respectively. In future scenarios, the percentage of groundwater flow and surface runoff contributions will be lesser due to the higher evapotranspiration rate and revaporisation of water to the root zone. Even though the monsoonal rainfall tends to reduce, the flow duration curves for the future scenarios exhibited a consistent increase in water availability compared to their respective historical counterparts, possibly due to more frequent and severe rainfall events.

Climate change impacts on hydroclimatic variables over Awash basin, Ethiopia: a systematic review

Latest Results

Abstract

Hydroclimate combines hydrology and climate variables, including the influence of water resources and their processes on Earth’s climate pattern and the change in the hydrological cycle. This review aimed to investigate the historical, current, and future projections of hydroclimatic variables within the Awash River basin. The spatiotemporal climate fluctuations caused by meteorological anomalies, catchment topographical processes, and human activities impact hydroclimatic variables. This systematic review was conducted to define and conceptualize hydroclimatic variables’ trends and variation. Scopus, Web of Science, and Google Scholar were used to assess relevant works of literature. Most of the rainfall stations in the basin exhibited an increasing and decreasing trend; however, this was not statistically significant. The mean, maximum, and minimum temperature variables continuously increased in the basin while streamflow declined. Besides, hydroclimatic variables and trends in response to climate change differ by local topography, length of data and statistical methods. Additionally, the basin encounters various trends and patterns in hydroclimate variables over time. This review emphasizes the importance of historical, current, and future climate change scenarios in the development of water resources and practices for sustainable environmental management. As a result, reviewing the findings provides a scientific basis for evidence-based practice for environmental and water resource managers, researchers, and policymakers.

Critical geopolitics in the era of identitarian populism

Latest Results

Abstract

The transformation of the current world paradigm is generating new, strong stimuli for geopolitical knowledge. The sharpened geopolitical competition grows from colorful mix of postmodern instruments, modern motivation, premodern and hybrid methods, clearly territorialized and deterritorialized threats, state-centric and diffusion processes. Identitarian populism, which restores the boundaries that have been pushed out of the political space by integration and globalization, is getting in the forefront of geopolitical discourse. In international relations, the clash of identities, their instrumentalization and revival of imperial dreams extend the area of critical geopolitics, which has instruments for exploring geographic permanence of power as well as identity discourse, and whose cognitive apparatus is therefore an attractive analysis tool. The article contributes to a debate about options for greater usability of sub-discipline in the new context, proposes arguments for depoliticization of critical geopolitics in the right-left plane, discusses possibilities for complementary, synthetic deployment of neoclassical and critical geopolitics in exploring new context and argues in favour of even closer cooperation with the international relations theory.

How do forewarnings and post-warnings affect misinformation reliance? The impact of warnings on the continued influence effect and belief regression

Latest Results

Abstract

People often continue to rely on certain information in their reasoning, even if this information has been retracted; this is called the continued influence effect (CIE) of misinformation. One technique for reducing this effect involves explicitly warning people that there is a possibility that they might have been misled. The present study aimed to investigate these warnings’ effectiveness, depending on when they were given (either before or after misinformation). In two experiments (N = 337), we found that while a forewarning did reduce reliance on misinformation, retrospectively warned participants (when the warning was placed either between the misinformation and the retraction or just before testing) relied on the misinformation to a similar degree as unwarned participants. However, the protective effect of the forewarning was not durable, as shown by the fact that reliance on the misinformation increased for over 7 days following the first testing, despite continued memory of the retraction.

Impact of energy efficiency information on homebuying searches: evidence from a visual choice experiment in the USA

Latest Results

Abstract

A lack of specificity exists on whether likely homebuyers utilize home energy efficiency information in future home searches. This study addresses this gap using a visual choice experiment to sample 1538 intended homebuyers in the USA, and the preference for home attributes through a simplified real estate website. Each home presented on the website featured six attributes: price, number of bedrooms, number of bathrooms, square footage, number of days on the market, energy efficiency, and a photo — each relative to participants’ initial specification of location, preferred price, number of bedrooms, and number of bathrooms. The respondents were assigned to one of six experimental conditions where energy information was provided as (i) estimated annual energy costs, (ii) home energy score (number only), (iii) home energy score along a continuum, (iv) estimated annual energy costs and energy score along a continuum, (v) home energy scores provided for only above average homes, and (vi) no energy information provided (control). We find that homebuyers are more likely to select energy efficient homes when presented with any form of energy efficiency information, with conditions that include home energy scores providing the greatest increase in energy efficiency. Furthermore, this preference for energy efficiency information persists even under less-than-ideal home searches. The preference for energy efficient homes is influenced by type of home and region with detached homebuyers and homebuyers in the Midwest US Census region more likely to select homes featuring higher energy efficiency scores. Finally, we find that rural homebuyers are more likely to prefer energy efficient homes over urban homebuyers.

Women’s Mental Health During COVID-19 in South Africa

Latest Results

Abstract

Women’s mental health vulnerability, already a concern before the COVID-19 pandemic, has been exacerbated due to social isolation and restrictions on daily activities. This paper aims to follow a cohort of women from pre - to during the pandemic to determine the change in their mental health using the PHQ-2 scale (a mental health screening tool). Additionally, we investigate whether women with depressive symptoms before the pandemic suffered similarly to those without while controlling for pandemic-related factors. Primarily, we use the Coronavirus Rapid Mobile Survey dataset and apply pooled ordered logit and fixed effects ordered logit models. We find that the value of the PHQ-2 scale significantly increased during the first period of the pandemic and then eased over time. Interestingly, the behaviour of the individual scale items differed over time. This result questions the internal reliability of the scale during the pandemic and the importance of analysing the scale items individually. Furthermore, being depressed before the pandemic increases the probability of ‘depressive feelings’ and does not matter for ‘anhedonia’. Other factors increasing the probability of mental health disorders are taking care of children for 13–24 h a day and living with a person who has gone hungry. In contrast, wearing a mask and living in a grant-receiving household decreases the probability. These findings inform future researchers of the unexpected behaviour of scales and policymakers of the vulnerability of women’s mental health during unprecedented times, given their vital role in increasing the well-being of future generations.

Australia and the Ukraine crisis: deterring authoritarian expansionism

Latest Results

Abstract

This paper seeks to explain Australia’s reaction to Russia’s invasion of Ukraine and how it has affected Australia’s strategic decisions in responding to Chinese aggression in the Indo-Pacific. Canberra’s responses are consistent with the ‘dependent ally’ and the ‘middle power’ traditions in Australian foreign policy. The paper argues that these responses are framed by assessments that a competition and struggle between a democratic and authoritarian bloc is occurring; authoritarian values and approaches are key causes of instability and disruption to the post-World War II liberal rules-based order; and should Moscow achieve its objectives in Ukraine and beyond, there is an increased possibility that Beijing will be tempted to use similar coercive measures against Taiwan and other nations. Canberra is consequently putting even more emphasis on the US-Australia alliance, and groupings such as AUKUS and the Quad as central to collective democratic action to constrain and deter contrary authoritarian behaviours in the Indo- Pacific.

Establishing altruistic ethics to use technology for Social Welfare—How Japan manages Web3 and self-sovereign identity in local communities

Latest Results

Abstract

Technologies of self-sovereign identity (SSI) and Web3 tools that strongly protect individual autonomy, combined with the ethics of Asian altruism, can effectively guide the governance of the emerging cyber civilization. In contrast, governance in Western industrial civilization stresses the pursuit of individual self-interest and struggles to balance the benefits of big tech with the protection of individual dignity and the preservation of the common good. We demonstrate, with reference to a local community in Japan, that SSI is successful in encouraging communal collaboration and well-being while providing individuals with greater control over their personal data. We also show that Web3 tools provide incentives for altruistic behaviors while safeguarding SSI. Integration of SSI and social protection demonstrates the potential for building an information society grounded in altruistic values, honoring individual dignity, and recognizing the government’s role in protecting social welfare. Ultimately, this research unveils how altruistic values can be fostered through SSI and Web3.
