Using a multinomial endogenous switching regression model, this study examined the factors that influence farmers’ decisions to adopt multiple integrated technologies and then estimated the effects of adopting integrated farm technologies on farm yield, farm income, and household food expenditure. The results showed that adopting higher-order suites of technologies provides higher dividends to farmers in terms of farm yield and income relative to a single technology adoption. 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. The study provides suggestive evidence for a shift in policy design for the country’s farm productivity coupled with investment policies that promote access to credit and education, especially among rural communities.

本研究采用多项内生转换回归模型,考察了影响农民采用多种综合技术决策的因素,并估计了采用综合农业技术对农业产量、农业收入和家庭粮食支出的影响。结果表明,相对于单一技术的采用,采用高阶技术套件在农业产量和收入方面为农民提供了更高的红利。研究发现,在不同的综合技术中,涉及作物和土壤创新的技术组合影响最大。然而,该研究的进一步发现表明,采用高阶技术包在食品支出方面没有统计学差异,尽管影响是积极的。这可以解释为什么获得的额外收益被转用于投资家庭资产、儿童教育和保健支出。此外,研究表明,户主的教育程度和获得信贷的机会对采用多种综合技术的决定有重大影响。该研究为该国农业生产力政策设计的转变以及促进获得信贷和教育的投资政策提供了启发性证据,特别是在农村社区。

This article intends to understand the impact of resettlement and upgrading in the context of Coimbatore, a second-tier city in India. It aims to explore the effects of these housing policies on the urban poor's daily lives and lived experiences by data triangulation. It describes these effects concerning residents’ social networks, livelihoods and commute, infrastructure and maintenance as well as process participation.

Most concerns raised for both resettlement and upgrading – such as destruction of livelihoods and social networks - that have so far primarily been investigated in bigger cities, are found to also apply for housing projects in this second-tier city. To a certain degree, location is an exemption here as three of the four investigated colonies are located near the city center, thereby enabling most of their residents to walk to work and many amenities. Public land in such a central location was thus available to the Urban Local Body (ULB). However, this land was found to be of low quality and rather unsuitable for construction. Overall, the lack of agency vested in residents during planning and implementation gravely contributed to several different projects’ deficiencies.

本文拟以印度二线城市哥印拜陀为背景,了解移民安置升级的影响。本文旨在通过数据三角分析,探讨这些住房政策对城市贫民日常生活和生活体验的影响。它描述了这些影响涉及居民的社会网络、生计和通勤、基础设施和维护以及过程参与。迄今为止,人们对安置和升级的担忧——比如对生计和社会网络的破坏——主要是在大城市进行的调查,发现这些担忧也适用于这个二线城市的住房项目。在某种程度上,地理位置在这里是一个豁免,因为四个被调查的殖民地中有三个位于市中心附近,因此大多数居民可以步行上班,并拥有许多便利设施。因此,这样一个中心位置的公共土地可供城市地方机构(ULB)使用。然而,这块土地被发现质量很低,不适合建设。总体而言,在规划和实施过程中,缺乏赋予居民的代理权,严重导致了几个不同项目的缺陷。

Exposure to environmental stressors during early childhood can significantly impact a child’s development and educational outcomes. 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.

儿童早期暴露于环境压力源会显著影响儿童的发展和教育成果。在本文中,我们研究了2007年至2014年期间孟加拉国儿童早期暴露于周围环境中未经改善的卫生设施对以后小学入学率的影响。虽然孟加拉国在消除露天排便方面取得了重大进展,但该国仍然无法充分获得改善的卫生设施。此外,尽管旨在提高小学入学率的政策自1990年代以来一直在实施,但在研究期间,许多学龄儿童没有在适当的时间入学。利用2007年、2011年和2014年国土安全部调查汇编的6至9岁儿童的伪面板数据集,我们发现,在其生命早期接触到较高比例未改善的社区卫生设施的儿童,在调查时入学的可能性平均降低了约5个百分点,这表明入学延迟。与8岁和9岁的孩子相比,这种影响在6岁和7岁的孩子身上更为明显,这可能是因为健康状况不佳或认知发育不佳的孩子的父母会推迟让他们的孩子上学,直到他们稍微大一点或更健康一些。我们的结果对潜在的遗漏变量偏差具有鲁棒性,并得到对匹配样本的额外分析的进一步支持。综上所述,我们的研究结果强调,扩大改善卫生设施的覆盖范围有助于提高入学率。但是,这不仅应在家庭一级进行,而且还应扩大到社区的所有家庭,以确保获得最大的利益。调查结果表明,提供更安全的卫生设施不仅本身有益,而且对于在整个人力资本开发周期,包括保健和营养以及教育方面实现改进也至关重要。

A five-year case study analysis of USAID local governance programming and public investment spending in post-earthquake Haiti 美国国际开发署在海地地震后的地方治理规划和公共投资支出的五年案例研究分析
IF 1.9 Q2 DEVELOPMENT STUDIES Pub Date : 2023-11-22 DOI: 10.1016/j.wdp.2023.100546

In the aftermath of the 2010 Haiti earthquake, the central government operations were paralyzed, and municipal officials became even more important as they were more readily able to respond to their constituents’ needs during this time of crisis. The United States Agency for International Development’s (USAID) five-year post-earthquake Limyè ak Òganizasyon pou Kolektivite yo Ale Lwen (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.

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.

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.

在2010年海地地震之后,中央政府的运作陷入瘫痪,市政官员变得更加重要,因为他们更容易在危机时刻对选民的需求做出反应。美国国际开发署(USAID)的5年震后Limyè ak Òganizasyon Kolektivite yo Ale Lwen (LOKAL+)项目旨在通过在地震灾区和非地震灾区开展收入动员活动,在震后加强市政当局的能力。这一努力的预期结果是改善海地各地提供的地方公共服务。从2012年到2017年,几乎所有参与local +的城市都增加了地方税收,特别是财产税和营业税。然而,这些增加对公共投资支出的影响并不明显,尽管这是该计划的既定目标。为了评估9个local +地区中的两个地区的公共服务是否因为美国国际开发署的地方收入动员而得到改善,我采用了一个案例研究分析,使用了描述性统计、深度访谈和内容分析。调查结果显示,在两个案例研究地点中,有一个地方的公共服务得到了适度改善。但是,执行LOKAL+时的政治气氛- -主要是当时在全国各地非法安装临时行政人员- -对研究结果产生了明显的影响。由于海地继续应对复杂的政治危机——包括2021年总统遇刺事件——自LOKAL+项目结束以来,具体国家的政治经济现实对捐助者主导的地方治理工作时机的影响得到了强调。

COVID-19, livelihoods and gender: Material, relational and subjective realities in rural Zambia 2019冠状病毒病、生计和性别:赞比亚农村的物质、关系和主观现实

This study explores material, relational and subjective elements of wellbeing as micro-level gendered impacts of COVID-19 policy responses on agro-based livelihoods. Using a test case of rural Zambia, we apply a mixed methods research design and draw data from household surveys, household case study interviews, group discussions, and multi-level interviews. 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.

本研究探讨了福祉的物质、关系和主观因素,即2019冠状病毒病政策应对对农业生计的微观层面性别影响。以赞比亚农村为例,采用混合方法研究设计,并从家庭调查、家庭案例研究访谈、小组讨论和多层次访谈中获取数据。结果显示,性别在四个重要的粒度水平上产生影响:市场和物质福利、家庭供应、劳动力和护理负担、关系和社会网络,以及对会员组织和社会倡议的破坏。导致市场中断的生产和流程导致经济活动的性别重新集中在男性周围,而男性则分别展示经济实力和蔑视COVID-19指南。另一方面,妇女被挤出生产和市场循环,迅速失去生计策略,被迫从事无偿和无形的家务劳动。尽管妇女努力寻找支持家庭的方法,例如努力维持集体储蓄倡议,但政策满意度低,包括产量下降和市场动态,限制了在农村地区采取包容和公平形式的COVID-19恢复行动。我们呼吁采取综合干预措施,考虑到社区生计模式及其如何受到这一大流行病的影响,因此必须注重地方推动的对性别问题敏感的举措,建立复原力并赋予妇女权力。

While the number of impact evaluations has increased in international development, the use of evidence has remained an issue. This study investigates and conceptualizes how a development agency can use evidence to improve and expand its development programs, taking the case of the Indian NGO “Pratham.” In a series of experiments with researchers, Pratham developed and refined their learning agenda to search for a better strategy to improve children’s foundational learning. Pratham has also regularly conducted a nationwide survey on children’s foundational learning. Data from the nationwide survey demonstrated the problem in children’s foundational learning, and evidence from experiments showed an option for an effective strategy to address it. The search, learning, and communication cycle using data and evidence, conceptualized from the case of Pratham, would enhance the effectiveness of development agencies to better support educational development.

虽然国际发展方面的影响评价数量有所增加,但证据的使用仍然是一个问题。本研究以印度非政府组织“Pratham”为例,对发展机构如何利用证据来改进和扩大其发展项目进行了调查和概念化。在与研究人员进行的一系列实验中,Pratham制定并完善了他们的学习议程,以寻找改善儿童基础学习的更好策略。普拉瑟姆还定期对全国儿童的基础学习情况进行调查。来自全国范围的调查数据显示了儿童基础学习中的问题,来自实验的证据显示了解决这个问题的有效策略的选择。利用数据和证据的搜索、学习和沟通循环将提高发展机构的效率,从而更好地支持教育发展。

The labour market dilemma of young urban women in India: An outcome of family welfare optimization 印度年轻城市女性的劳动力市场困境:家庭福利优化的结果

This paper uses a theoretical model to explain the patterns and determinants of labour market participation behaviour of young urban women in India. Based on the National Sample Survey (NSS) data and through probit regression results, it argues that the labour market participation decision of young women is an outcome of the joint utility maximization behaviour of their family. The standard of living of the family, market wage, other family characteristics, including the number of children, adult women in the family, elderly members, and occupation, and gender of the head, etc., are significantly determining their labour market participation; apart from women’s individual characteristics like age (experience) and level of education and training. The empirical result also reflects that the “discouraged worker effect” is stronger than the “added worker phenomenon”. Hence, measures to create jobs in modern services could help boost the stagnant female labour force participation in urban India.

本文使用理论模型来解释印度城市年轻女性劳动力市场参与行为的模式和决定因素。基于全国抽样调查(NSS)数据,通过probit回归结果,认为年轻女性的劳动力市场参与决策是其家庭共同效用最大化行为的结果。家庭的生活水平、市场工资、其他家庭特征,包括子女的数目、家庭中的成年妇女、老年成员、职业和户主的性别等,都在很大程度上决定着她们参与劳动力市场的情况;除了妇女的个人特征,如年龄(经验)和教育和培训水平。实证结果也反映出“气馁工人效应”强于“增加工人现象”。因此,在现代服务业创造就业机会的措施可能有助于提高印度城市停滞不前的女性劳动力参与率。

Enhancing productivity and profitability of farm households were key focuses among Nigerian agricultural policymakers in their design of the Agricultural Transformation Agenda (ATA) of 2011–2015. There were several prominent policy initiatives and market development activities included in the ATA. 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. Overall, the policy and market development activities appear to have achieved some intended outcomes among farm households in both peri-urban and rural areas, but the impacts were most pronounced among households nearest to markets.

提高农户的生产力和盈利能力是尼日利亚农业政策制定者在制定2011-2015年农业转型议程(ATA)时关注的重点。ATA中包括了几项突出的政策倡议和市场发展活动。实施这些政策的主要直接影响是增加了补贴肥料和种子的公共支出,提高了补贴接受者的平均生产力。还有一些间接影响是公众对农业发展倡议有了更高的认识,并增加了农场投入。然而,由于与农村地区相比,城市的物质和交通基础设施相对更大,我们假设,与农村农户相比,离市场最近的城郊地区的农户更能从这些举措中受益。在此背景下,本文的实证分析估计了城郊农户与农村农户在ATA政策实施期间在农产品营销和农业投入购买决策方面的差异。研究结果支持了城郊农户比农村农户更大程度地增加农业投入的购买,以及更高的作物销售价值的假设。数据限制不允许确定相对较高的作物销售价值的因果原因。总的来说,政策和市场开发活动似乎在城郊和农村地区的农户中取得了一些预期的成果,但影响在离市场最近的农户中最为明显。

Achieving sustainable development requires peaceful conditions. However, current sustainability impact assessment tools tend to overlook aspects of positive peace, particularly in societies transitioning from conflict. Recent efforts attempt to address this gap, but the examination of how positive peace indicators integrate into major global sustainability assessment (GSA) frameworks remains underexplored. 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.

实现可持续发展需要和平条件。然而,目前的可持续性影响评估工具往往忽视了积极和平的各个方面,特别是在从冲突过渡的社会中。最近的努力试图解决这一差距,但对积极的和平指标如何融入主要的全球可持续性评估框架的审查仍然没有充分探索。这项研究评估了GSA框架是否考虑了积极的和平或消除结构性暴力以及维持和平的有利社会条件。我们选择了八个GSA框架进行分析:环境绩效指数、全球绿色经济指数、绿色增长指数、全球可持续竞争力指数、幸福星球指数、行星调整后的人类发展指数、可持续发展目标指数和可持续社会指数。我们首先使用Bellagio可持续性评估和衡量原则(BellagioSTAMP)评估了八个GSA框架,包括指导愿景、基本考虑因素、适当的范围、框架和指标、透明度、有效沟通、广泛参与以及连续性和能力。然后,我们分析了框架中的综合指标,以确定它们是否平衡关注不同的可持续性层面,并将积极的和平纳入其中。虽然使用BellagioSTAMP进行的评估总体上令人满意,但尽管和平是可持续发展的先决条件,但在一些框架中,积极的和平问题没有得到充分解决。研究结果可以为制定更好地整合和平与可持续性组成部分的评估框架提供信息。该研究还强调了积极和平对实现可持续发展的重要性,以及确保评估框架为建设和平社区的行动提供信息的必要性。

Beyond the numbers: Group formation in the artisanal and small-scale mining in Ghana 数字之外:加纳手工和小规模采矿的群体形成

The dramatic increase in Artisanal and Small-scale gold mining (ASM) in the developing world, especially sub-Saharan Africa, is not a happenstance. This has been due to the steady decline in livelihoods based on agriculture and the increasing destitution of many households in these areas. In Ghana, the ASM sector is ever-expanding, providing direct employment for many individuals. 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. Still, if they have internal structures which are well organised, they can be relied upon in a comprehensive sanitization.

发展中国家,特别是撒哈拉以南非洲地区手工和小规模金矿开采的急剧增加并非偶然。这是由于以农业为基础的生计稳步下降,以及这些地区许多家庭日益贫困。在加纳,ASM部门不断扩大,为许多人提供了直接就业机会。然而,这项活动的性质是劳动密集型的,因此需要矿工合作和分组工作。尽管传统上,数量在集团形成中很重要,但本文认为,规模并不是组建矿业集团的关键考虑因素。基于在加纳比林北区的实地调查,通过焦点小组讨论和访谈,论文发现领导力、互惠、信任和相互尊重等问题有助于形成ASM小组。受访者并不忽视通过多个地点加强他们的联系,他们认为,与规模相比,领导素质和遵守规则和安排的问题是组建团队的重要考虑因素。建议利益相关者认真审视ASM,以净化和改善ASM矿工的认知,因为他们组织良好。尽管如此,如果它们的内部结构组织良好,那么在全面的消毒中就可以依赖它们。
