Among different integrated technologies, the study found that the technology mix involving crop and soil innovations exerts the greatest impact. Further findings from the study, however, shows that there are no statistical differences in food expenditure from adopting higher-order packages of technologies, albeit the impacts being positive. This could explain the diversion of additional gains obtained towards investing in family assets, child education, and health expenditures. In addition, the study suggests that the level of education of the family head and access to credit significantly influence the decision to adopt multiple integrated technologies.

In this paper, we examine the effects of exposure to unimproved sanitation in the surrounding environment during early childhood on primary school enrollment later in life in Bangladesh between 2007 and 2014. While Bangladesh has made significant progress towards eradicating open defecation, the country still suffers from inadequate access to improved sanitation. Additionally, although policies aiming at improving primary school enrollment have been in place since the 1990s, many children of school age were not enrolled at the appropriate time during the period studied. Using a pseudo-panel dataset for children aged six to nine compiled from the 2007, 2011, and 2014 DHS surveys, we find that children exposed to a higher proportion of unimproved sanitation in their community early in their life are less likely to be enrolled in primary school at the time of survey by about five percentage points on average, indicating delayed school enrollment. This effect is more pronounced for children aged six and seven than those eight and nine, likely because parents of children experiencing poor health or cognitive development delay enrolling their children in school until they are slightly older or healthier. Our results are robust to potential omitted variable biases and are further supported by additional analyses on matched samples. Taken all together, our findings highlight that increasing coverage of improved sanitation facilities can help improve school enrollment rates. However, this should not only occur at the household level alone but also should extend to cover all households in the community to ensure achieving maximum benefits. The findings indicate that the provision of safer sanitation facilities is not only good by itself but also is crucial for achieving improvements throughout the human capital development cycle, including health and nutrition, as well as education.</p></div>","PeriodicalId":37831,"journal":{"name":"World Development Perspectives","volume":"32 ","pages":"Article 100543"},"PeriodicalIF":1.9,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138391243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The United States Agency for International Development’s (USAID) five-year post-earthquake <em>Limyè ak Òganizasyon pou Kolektivite yo Ale Lwen</em> (LOKAL+) program aimed to bolster the capacity of municipalities – beyond this disaster event – through revenue mobilization activities, within quake-affected and non-quake affected areas. The intended outcome of this effort was to improve local public service delivery throughout Haiti.</p><p>Nearly all participating LOKAL+ municipalities experienced increased local revenue collection, particularly in property and business taxes, from 2012 through 2017. However, the impact of these increases on public investment spending was not evident even though this was a stated objective of the program. To evaluate whether public services improved in two of the nine LOKAL+ localities, due to USAID’s local revenue mobilization efforts, I employed a case study analysis using descriptive statistics, in-depth interviewing, and content analysis.</p><p>The findings revealed modest public service improvements in one of the two case study sites. However, the political climate within which LOKAL+ was executed – mainly, the unlawful installation of interim executive agents throughout the country at the time – had an observed impact on the study’s findings. The implications of country-specific political economic realities on the timing of donor-led local governance efforts are underscored, as Haiti continues to navigate compounding political crises – including the assassination of the President in 2021 – since the end of the LOKAL+ program.</p></div>","PeriodicalId":37831,"journal":{"name":"World Development Perspectives","volume":"32 ","pages":"Article 100546"},"PeriodicalIF":1.9,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138396474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show gendered impacts at four significant levels of granularity: markets and material wellbeing, household provisioning, labour and care burdens, relationships and social networks, and disruptions to membership organisations and social initiatives. Production and processes leading to market disruptions lead to a gendered reconcentration of economic activities around men who flex financial muscle and flout COVID-19 guidelines respectively. Women on the other hand are squeezed out of production and market circuits, quickly loosing livelihood strategies and getting relegated to unpaid and invisible household work. Whereas women endeavour to find ways to support their families, such as attempting to maintain group savings initiatives, low levels of policy satisfaction, including declining production and market dynamics limit actions towards inclusive and equitable forms of COVID-19 recovery in rural geographies. We call for holistic interventions that consider community patterns of livelihoods and how they are impacted by the pandemic, necessitating a focus on gender sensitive initiatives that are locally driven, build resilience and empower women.</p></div>","PeriodicalId":37831,"journal":{"name":"World Development Perspectives","volume":"32 ","pages":"Article 100547"},"PeriodicalIF":1.9,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2452292923000632/pdfft?md5=c214dfbb7acf9b7982ed87c6810cb9a6&pid=1-s2.0-S2452292923000632-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138136208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main direct effects of implementing them were increased public expenditures on subsidized fertilizer and seeds and increased average productivity among subsidy recipients. There were also indirect effects pertaining to greater awareness of agricultural development initiatives among the public and increased farm input availability. However, due to relatively greater physical and transportation infrastructure in urban relative to rural areas, we hypothesized that farm households in peri-urban regions nearest to markets were better positioned to benefit from such initiatives as compared to rural farm households. In this context, the empirical analysis in this article estimates differences among peri-urban versus rural farm households regarding their crop produce marketing and farm input purchase decisions during the period of ATA policy implementation. The results support the hypothesis that peri-urban farm households increased purchases of farm inputs to a greater degree than did rural farm households as well as had higher crop sales values. Data limitations do not allow for determining the causal reason for relatively higher crop sales values.

This study evaluates whether GSA frameworks consider positive peace or the elimination of structural violence and enabling societal conditions that sustain peace. We selected eight GSA frameworks for the analysis: Environmental Performance Index, Global Green Economy Index, Green Growth Index, Global Sustainable Competitiveness Index, Happy Planet Index, Planetary Adjusted Human Development Index, Sustainable Development Goals Index, and Sustainable Society Index. We first evaluated the eight GSA frameworks using the Bellagio Sustainability Assessment and Measurement Principles (BellagioSTAMP) covering guiding vision, essential considerations, adequate scope, framework and indicators, transparency, effective communication, broad participation, and continuity and capacity. Then we analyzed consolidated indicators from the frameworks to determine if they pay balanced attention to different sustainability dimensions and integrate positive peace. While evaluation using BellagioSTAMP is generally satisfactory, positive peace is inadequately addressed in some frameworks, despite peace being a prerequisite for sustainable development. The study results can inform the development of assessment frameworks that better integrate the components of peace and sustainability. The study also highlights the importance of positive peace in achieving sustainable development and the need to ensure assessment frameworks inform actions toward building peaceful communities.</p></div>","PeriodicalId":37831,"journal":{"name":"World Development Perspectives","volume":"32 ","pages":"Article 100539"},"PeriodicalIF":1.9,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49710481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nature of the activity, however, is labour-intensive and thus requires the miners to collaborate and work in groups. Even though traditionally, numbers have mattered in group formation, this paper argues that size is not a critical consideration in forming mining groups. Based on fieldwork in the Birim North District of Ghana using focus group discussions and interviews, the paper found that issues of leadership, reciprocity, trust, and mutual respect are instrumental in forming ASM groups. Not discounting the strengthening of their bonds through multiple locations, the respondents are empathic that rather than size, issues of leadership qualities and conformity to rules and arrangements are vital considerations for group formation. It is recommended that stakeholders take a critical look at ASM to sanitise and improve the perception of the ASM miners as they are well-organised.
