The role of climate change perceptions and sociodemographics on reported mitigation efforts and performance among households in northeastern Mexico

Managing and reducing the impacts of climate change depends on efficient actions from all societal scales. Yet, the household component is often missing from climate research, debate, and policies. This is problematic because households have been found to significantly contribute to of global greenhouse gas emissions and therefore have the potential to be part of a solution to climate change by mitigating climate change. This study seeks to understand which factors drive household-level mitigation actions. We conducted a household survey in Nuevo Leon, located in northeastern Mexico, to explore the extent to which climate change perceptions and the sociodemographic characteristics of households influence their reported mitigation performances and their perceived mitigation efforts. Results from linear regression analyses and generalized linear models revealed that sociodemographic characteristics are key drivers of the households’ perceived mitigation efforts and reported mitigation performances and. We also found that climate change perceptions drive a household’s efforts to mitigate climate change. These results could partly explain why despite the efforts households take to mitigate climate change, achieving an effective reduction of greenhouse gas emissions is challenging without further access to resources such as education and financial support. If governments intend to realize substantial reductions in future emission pathways, then household-level mitigation should be addressed with proper support.

Household Customers’ Cost of Interruption: Survey Study on Summer Electricity Peak of Xi’an City

In light of China’s Carbon Neutrality Target and facing the fluctuating pressure of power supply brought on by new energy intermittent power generation, it is urgent to mobilize a large number of residential flexible loads that can respond instantaneously to mitigate peak–valley difference. Under a framework of demand-side management (DSM) and utility analysis, we empirically investigate customers’ costs from interrupting typical electrical terminals at the household level. Specifically, by using the contingent valuation method (CVM), we explore the factors that affect households’ Willingness to Accept (WTA) of voluntarily participating in the interruption management during the summer electricity peak and estimate the distribution of households’ WTA values. We find that given the value of WTA, households’ participation rate in the interruption management significantly decreases with the increase in interruption duration and varies with the type of terminal appliance that is on direct interruption management. Moreover, the majority of households are willing to participate in the interruption management even if the compensation amount is low. The factors that determine households’ WTA and the size of their influences vary with the type of electrical terminal. The results imply that differentiating the terminal electricity market and accurately locking on the target terminals by considering the household heterogeneity can reduce the household welfare losses arising from DSM.

Resilience in agroecosystems: an index based on a socioecological systems approach

This article presents an agroecosystem resilience index (ARI) relative to two types of exogenous drivers: biophysical and socioeconomic threats. The ARI is based on a theoretical framework of socioecological systems and draws upon multicriteria analysis. The multicriteria consists of variables related to natural, productive, socioeconomic, and institutional systems that are weighted and grouped through expert judgment. The index was operationalized in the Rio Grande Basin (RGB), in the Colombian Andes. The ARI was evaluated at the household level using information from 99 RGB households obtained through workshops, individual semistructured interviews, and surveys. The ARI is a continuous variable that ranges between zero and one and results in five categories of resilience: very low, low, medium, high, and very high. When faced with climate change impacts, 19% of households showed low resilience, 64% medium resilience, and 16% high resilience according to the ARI. When faced with price fluctuations, 23% of households showed low resilience, 65% medium resilience, and 11% high resilience. Key variables associated with high resilience include the diversity of vegetation cover, households that have forests on their properties, a high degree of connectivity with other patches of forest, diversification of household economic activities, profitability of economic activities, availability of water sources, and good relationship with local institutions.

Public Investments and Class Gaps in Parents’ Developmental Expenditures

Families and governments are the primary sources of investment in children, providing access to basic resources and other developmental opportunities. Recent research identifies significant class gaps in parental investments that contribute to high levels of inequality by family income and education. State-level public investments in children and families have the potential to reduce class inequality in children’s developmental environments by affecting parents’ behavior. Using newly assembled administrative data from 1998 to 2014, linked to household-level data from the Consumer Expenditure Survey, we examine how public-sector investment in income support, health, and education is associated with the private expenditures of low- and high-SES parents on developmental items for children. Are class gaps in parental investments in children narrower in contexts of higher public investment for children and families? We find that more generous public spending for children and families is associated with significantly narrower class gaps in private parental investments. Furthermore, we find that equalization is driven by bottom-up increases in low-SES households’ developmental spending in response to progressive state investments of income support and health, and by top-down decreases in high-SES households’ developmental spending in response to universal state investment in public education.

Impact of climate change on domestic water accessibility in Bamenda III Sub-Division, North West region, Cameroon

The effects of climate change are felt most at the household level, when taps and springs run dry for several weeks or months, forcing people to access potable water from doubtful sources. There has been an increase in the population of Bamenda III without a proportionate increase in the water supply capacity. This has resulted in severe water crises, even though Bamenda III municipality has water supplies from the Council, Community, CAMWATER, natural springs and streams, wells and boreholes. Household data on water accessibility against a backdrop of a changing climate was collected using 269 questionnaires to assess perceptions on the state of water resources and climate. Rainfall data were collected from 1963-2019 and results revealed that mean annual rainfall is at 182.52 mm, with a standard deviation of 29.16 and a Coefficient of Variation of 15.69%, while the mean Standardized Precipitation Index is -0.07 (mild dryness), and rainfall has reduced by -2.07 mm from 1963-2019. The population attributed problems of water accessibility to climate change, urbanization and poor water governance. It is recommended that sustainable water management through Nature-based Solutions and Ecosystem-based Adaptation should be implemented from the watershed to the community level.

Assessment of Local Adaptive Capacity of Mountain Farmers: A Way Forward for Sustainable Livelihood Development

This study aims to understand the perception of mountain farmers towards the local adaptive capacity at a household level in an agro-ecological landscape. An indicator-based assessment is conducted to examine the 6 determinants and 27 indicators to give a local adaptive capacity index of the villages around Govind Wildlife Sanctuary and National Park, located in the Indian Himalayan region. The findings indicate that, though the connected and isolated villages have a low and very low adaptive capacity, respectively, the effect of various determinants on the local people varies among the village settlements, based on their socio-economic capacity. Despite the government endeavours to build the livelihood of mountain farmers through different programmes and policies, it still lacks proactive decision-making. The study suggests for an integrated assessment and sustainable enhancement of the landscape as a whole, with a focus on community-level adaptation strategies. It draws attention to the need for enhanced collaboration between research institutions, government and private sectors with the mountain community in the centre.

Sustainable Water and Sanitation in Sierra Leone: Impact evaluation of the ‘Improved WASH Services in WAU and WAR Districts’ project

Between October 2016 and March 2019, the Freetown WASH Consortium, led by Oxfam with Against Hunger, Concern Worldwide and Save the Children as members, carried out the 'Improved WASH Services in Western Area Urban (WAU) and Western Area Rural (WAR) Districts' project. Broadly, the project aimed to improve the availability, accessibility, affordability and sustainability of integrated water, sanitation and hygiene (WASH) services, in alignment with the Government of Sierra Leone's national agenda on Ebola recovery and increased preparedness against possible future outbreaks. This Effectiveness Review evaluates the success of this project to increase the sustainability of water and sanitation systems and services. Using a quasi-experimental, mixed method evaluation design, impact is assessed among individuals, households and communities in intervention and comparison areas.
