In recent years, the water–energy–food (WEF) nexus approach has been widely used as a framework in the context of urban Sustainability. However, some elements of the approach are normative, leading to a technical view of resources and technocratic policy implementation. To avoid such tendencies, this study uses the framework of ‘nexus of humility’. We used insights from the Science and Technology Studies to better assess the interactions between water, energy, and food, and consider the social construction aspects of the nexus itself. The approach of Pathways to Sustainability is combined with this framework to analyze two government programs in the cities of São Paulo and Guarulhos, Brazil; namely, the Green and Healthy Environments Program and the Environmental Health Program, respectively. We interviewed 20 individuals linked to these policies and analyzed narratives inductively and deductively. The results showed six groups of narratives, namely: environmental and social determinants of health, health prevention and promotion, intersectorality, politics and economy, territory, learning, and participation. Moreover, we concluded that narratives related to the WEF nexus, even if not explicitly part of the government guidelines, are present within the existing axes of action. Public health was understood as an important support pillar for the development of synergies related to Sustainability in urban areas. Finally, we sought to contribute to the literature by showing how this new framework can ‘open up’ avenues for sustainability within the contexts of high urban vulnerability and social inequality.
近年来,水-能源-食物(WEF)联系方法被广泛用作城市可持续发展的框架。然而,该方法的一些要素是规范性的,导致对资源和技术官僚政策执行的技术观点。为了避免这种倾向,本研究使用了“谦逊关系”的框架。我们利用科学技术研究的见解来更好地评估水、能源和食物之间的相互作用,并考虑关系本身的社会建设方面。可持续发展之路的方法与该框架相结合,分析了巴西圣保罗和瓜鲁洛斯市的两个政府项目;分别是绿色和健康环境方案和环境健康方案。我们采访了20位与这些政策有关的个人,并对叙述进行归纳和演绎分析。结果显示了六组叙述,即:健康的环境和社会决定因素、预防和促进健康、交叉性、政治和经济、领土、学习和参与。此外,我们得出的结论是,与世界经济论坛联系相关的叙述,即使不是政府指导方针的明确组成部分,也存在于现有的行动轴中。公共卫生被理解为在城市地区发展与可持续性有关的协同增效作用的重要支助支柱。最后,我们试图通过展示这个新框架如何在城市高度脆弱性和社会不平等的背景下为可持续发展“开辟”道路,从而为文献做出贡献。

Social structure is based on the availability of the Water-Energy-Food Nexus. To cover these needs of society, several solutions of different scales of infrastructures coexist. The construction of infrastructure is capital-intensive; therefore, investment risk is always a consideration. In this paper, we try to evaluate the investment risk by interest rates (IR). We show that IR is a key indicator, which includes multiple parameters of prosperity expressing the political and economic status quo of the society. The selection of a particular scale influences the required capital and is thus one of the most critical decisions. Water supply infrastructure is one of the foundations of society, and the selection of the optimal scale of such infrastructure is often a great challenge in civil engineering. As a case study, we analyse three different scales of water supply infrastructures for the area of West Mani (Greece), i.e., dam, water ponds, and seawater desalination. We evaluate each case by the capital intensity by performing stochastic simulations of interest rates and identify the optimal solution as the one with the smallest median unit cost, in this case, the water ponds. In order to assess the impact of the development level of a country on the resulting unit cost stochastic properties we apply the optimal solution to various countries with different development levels and IR. We show that IR in the least developed countries, being generally higher and more variable, increases the unit cost, including its variability, which ultimately indicates higher investment risk.
社会结构的基础是水-能源-粮食关系的可用性。为了满足社会的这些需求,几种不同规模的基础设施并存的解决方案。基础设施建设是资本密集型的;因此,投资风险总是一个需要考虑的因素。本文尝试用利率(IR)来评估投资风险。我们表明,IR是一个关键指标,它包括表达社会政治和经济现状的繁荣的多个参数。特定规模的选择影响所需的资本,因此是最关键的决定之一。供水基础设施是社会的基础之一,供水基础设施的最佳规模选择往往是土木工程中的一大挑战。作为案例研究,我们分析了西马尼(希腊)地区三种不同规模的供水基础设施,即水坝、池塘和海水淡化。我们通过对利率进行随机模拟,通过资本密集度来评估每种情况,并确定最优解决方案为单位成本中值最小的解决方案,在这种情况下,是池塘。为了评估一个国家的发展水平对单位成本随机特性的影响,我们将最优解应用于具有不同发展水平和IR的不同国家。我们发现,最不发达国家的投资回报率普遍较高且变化较大,这增加了单位成本,包括其变异性,最终表明投资风险较高。

Closed Season Policy Is Only Partly Practiced in Surigao del Sur, Philippines 禁渔期政策只在菲律宾的南苏里高部分实行

Small-scale fisheries (SSF) make a critical contribution in terms of employment and food security to coastal communities. Fish serves multiple purposes, mainly as a cheap source of protein and minerals for lower-income families. In order to help sustain this demand and to protect fishing resources, the closed season policy, temporal closure, and spatial closure were adopted to protect fish stocks and avoid fishery collapse. To assess the agreement and compliance of the three municipalities (Cortes, Lanuza, and Lianga) in Surigao del Sur to this policy, we surveyed their responses regarding this policy. We used focus group discussions, two focus groups per municipality (N = 80), followed by member checking to gather and clarify the data from six barangays with small-scale fishers (N = 192). The findings indicate that each community in the three municipalities studied have a different method of implementing the fishery closure or closed fishing season policy which resulted in a limited conservation impact on fish stocks. In the municipality of Cortes, 92% agreed with the policy, provided there would be enough money to comply with the policy. In Lanuza, 60% agreed to implement the policy, provided there would be alternative jobs available. In contrast, the municipality of Lianga, which did not implement this policy, had only 4% that agreed to impose the policy to restore depleted fish stocks. Other reasons for not implementing a closed season policy include lack of community organization, poor fishery management, and lack of strong government support for the policy. Moreover, fishers were only willing to stop fishing if they were given a subsidy of PHP 15,000 per month. In the long term, fishers who provide fish protein needs for the nation also need help and attention from policy and decision makers to realize sustainable fisheries.
小规模渔业在沿海社区的就业和粮食安全方面作出了重要贡献。鱼有多种用途,主要是作为低收入家庭廉价的蛋白质和矿物质来源。为了维持这种需求和保护渔业资源,采取了封季、时间封禁和空间封禁政策,以保护鱼类资源,避免渔业崩溃。为了评估南苏里高三个市(科尔特斯、拉努扎和良加)对这项政策的同意和遵守情况,我们调查了他们对这项政策的反应。我们采用焦点小组讨论,每个城市两个焦点小组(N = 80),然后进行成员检查,以收集和澄清来自六个小规模渔民村(N = 192)的数据。调查结果表明,所研究的三个市的每个社区都有不同的执行渔场关闭或休渔期政策的方法,结果对鱼类资源的养护影响有限。在科尔特斯市,92%的人同意这项政策,前提是有足够的资金来执行这项政策。在拉努扎,60%的人同意实施这项政策,只要有其他工作机会。相比之下,没有实施该政策的良加市只有4%的人同意实施该政策,以恢复枯竭的鱼类资源。不执行禁渔期政策的其他原因包括缺乏社区组织、渔业管理不善以及缺乏政府对该政策的有力支持。此外,渔民只有在得到每月15 000菲律宾比索的补贴时才愿意停止捕鱼。从长远来看,为国家提供鱼类蛋白质需求的渔民也需要政策和决策者的帮助和关注,以实现可持续渔业。

Community Counts: Rural Social Work in East Africa 社区计数:东非农村社会工作
Pub Date : 2022-12-09 DOI: 10.3390/world3040060

The community plays a significant role in everyday life in rural African contexts, particularly in terms of coping and in times of crisis. In the East African region, rural communities are diverse and complex, yet most share similar vulnerabilities such as widespread poverty, lack of infrastructure and basic services, and exclusion from broader economic and political developments. They are also highly affected by processes of modernization, globalization, and rural-urban migration. Social work as a profession that deals with social problems is deemed suitable to support rural communities in their struggle for survival. In order to understand the link between community-based forms of problem solving and social work practice, a qualitative study was conducted in five countries (Burundi, Kenya, Rwanda, Tanzania, and Uganda). A total of 155 qualitative interviews and 55 focus group discussions with key informants were conducted. The research revealed a variety of indigenous knowledge systems and innovative coping mechanisms. For rural social work to be relevant and effective, such models should be thoroughly analyzed and integrated into its professional concepts and practice. In this article, some case examples are presented and critically discussed against the background of the African philosophical concept of ubuntu, which is regarded as the ethical backbone of communal life.
社区在非洲农村的日常生活中发挥着重要作用,特别是在应对危机和危机时期。在东非地区,农村社区多样而复杂,但大多数农村社区都有类似的脆弱性,如普遍贫困、缺乏基础设施和基本服务、被排除在更广泛的经济和政治发展之外。它们也受到现代化、全球化和城乡迁移进程的高度影响。社会工作作为一种处理社会问题的职业,被认为适合支持农村社区的生存斗争。为了了解以社区为基础的解决问题形式与社会工作实践之间的联系,在五个国家(布隆迪、肯尼亚、卢旺达、坦桑尼亚和乌干达)进行了定性研究。共进行了155次定性访谈和55次与主要举报人的焦点小组讨论。研究揭示了多种本土知识体系和创新的应对机制。要使农村社会工作具有针对性和有效性,就必须对这些模式进行深入分析,并将其融入到农村社会工作的专业理念和实践中。在这篇文章中,提出了一些案例,并在非洲哲学概念乌班图的背景下进行了批判性的讨论,乌班图被认为是社区生活的伦理支柱。

Assessing Lactation Curve Characteristics of Dairy Cows Managed under Contrasting Husbandry Practices and Stressful Environments in Tanzania 评估坦桑尼亚不同饲养方式和应激环境下奶牛的泌乳曲线特征

The ability of smallholder dairy farming systems (SHDFS) to achieve desirable lactation-curve characteristics is constrained or reduced by environmental stresses. Under stressful production environments in the tropics, the better lactation-curve characteristics in smallholder dairy farms are a result of improved dairy genetics and husbandry practices. Better husbandry practices improve animal health and welfare status, which is important to sustain SHDFS in the tropics where dairy cattle are constantly exposed to multiple environmental stresses of feed scarcity, disease infections and heat load. In this case, lactating cows in smallholder dairy farms labelled positive deviants are expected to express lactation curve characteristics differently from typical farms, regardless of the stress levels confronted. Thus, this study tested this hypothesis with Holstein–Friesian and Ayrshire cows in two milksheds in Tanzania classified them into low-and high-stress environments. A two-factor nested research design was used, with farm (positive deviant and typical) nested within the environment. Positive deviant farms were farms that performed above the population average, attaining ≥0.35 Mcal NEL/d energy balance, ≥6.32 L/cow/day milk yield, ≤1153.28 days age at first calving, ≤633.68 days calving interval and ≤12.75 per 100 animal-years at risk disease-incidence density. In this study, a total of 3262 test-day milk production records from 524 complete lactations of 397 cows in 332 farms were fitted to the Jenkins and Ferrell model to estimate lactation curve parameters. In turn, the outcome parameters a and k were used to estimate lactation curve characteristics. The lactation curve characteristic estimates proved the study hypothesis. Regardless of the stress levels, cows in positive deviant farms expressed lactation curve characteristics differently from cows managed in typical farms. The scale (a) and shape (k) parameters together with peak yield and time to peak yield indicated higher lactation performance in positive deviant farms than in typical farms under low- and high-stress environments (p < 0.05). Lactation persistency was higher in positive deviants than typical farms by 14.37 g/day and 2.33 g/day for Holstein–Friesian cows and by 9.91 g/day and 2.16 g/day for Ayrshire cows in low- and high-stress environments. Compared to cows managed in typical farms, cows in positive deviant farms attained higher lactation performance under low- and high-stress; Holstein–Friesian produced 50.2% and 36.2% more milk, respectively, while Ayrshire produced 52.4% and 46.0% more milk, respectively. The higher milk productivity in positive deviant farms can be associated with the deployment of husbandry practices that more effectively ameliorated feed scarcity, heat load and disease infections stresses, which are prevalent in tropical smallholder dairy farms.
小农奶牛养殖系统(SHDFS)实现理想的泌乳曲线特征的能力受到环境压力的限制或降低。在热带紧张的生产环境下,小农奶牛场更好的泌乳曲线特征是奶牛遗传和饲养方法改进的结果。更好的畜牧业做法可以改善动物健康和福利状况,这对于维持热带地区的SHDFS至关重要,因为热带地区的奶牛经常面临饲料短缺、疾病感染和热负荷等多重环境压力。在这种情况下,无论面临的压力水平如何,标记为阳性偏差的小农奶牛场的泌乳奶牛预计会表现出与典型农场不同的泌乳曲线特征。因此,本研究在坦桑尼亚的两个奶牛场用荷尔斯坦-弗里西亚奶牛和艾尔郡奶牛验证了这一假设,并将它们分为低压力和高压力环境。采用双因素嵌套研究设计,将农场(正偏差和典型)嵌套在环境中。阳性异常农场是指高于种群平均水平的农场,能量平衡≥0.35 Mcal NEL/d,产奶量≥6.32 L/头/天,初产犊龄≤1153.28日龄,产犊间隔≤633.68天,危险疾病发病率密度≤12.75 / 100动物年。本研究拟合332个奶牛场397头奶牛524次完全泌乳的3262个试验日产奶量记录,采用Jenkins和Ferrell模型估计泌乳曲线参数。结果参数a和k依次用于估计泌乳曲线特征。泌乳曲线特征估计证实了研究假设。无论应激水平如何,阳性偏差农场奶牛的泌乳曲线特征与典型农场奶牛不同。规模(a)和形状(k)参数以及产峰量和到达产峰时间均表明,在低、高应激环境下,正向偏差农场的泌乳性能高于典型农场(p < 0.05)。在低应激和高应激环境下,荷斯泰因-弗里西亚奶牛的泌乳持续度比典型农场高14.37 g/d和2.33 g/d,艾尔郡奶牛的泌乳持续度比典型农场高9.91 g/d和2.16 g/d。与典型农场管理的奶牛相比,正偏差农场的奶牛在低应激和高应激下获得了更高的泌乳性能;荷尔斯坦-弗里西亚奶牛产奶量分别高出50.2%和36.2%,而艾尔郡奶牛产奶量分别高出52.4%和46.0%。积极偏差农场较高的产奶量可能与采用更有效地改善饲料短缺、热负荷和疾病感染压力的畜牧业做法有关,这些问题在热带小农奶牛场普遍存在。

Researching Rural Development: Selected Reflections 农村发展研究:若干思考
Pub Date : 2022-12-05 DOI: 10.3390/world3040058
A. Fuller
Reflections on research can take many forms. They inevitably contain positive memories of research that advanced our knowledge on issues of the day. They can also reflect dead ends and disappointments. Although research in rural development is generally a public endeavor (government, university and NGO supported projects), the effects felt by the researcher are often personal. Meeting peasants in the field, listening to abused farm women, and tracing livelihood transitions are all challenging for the researcher. Above all, making sense of research results for policy development is a daunting task, as there are many layers of dilution and deflection between researcher and policy maker. With these impediments and opportunities in mind, I offer some of my own reflections, in the form of an opinion piece, on rural development research over the past 50 years. The paper is organized into three parts: macro and micro level observations about the evolution and prevailing trends in rural development, and a third section on contemporary and future issues.
对研究的反思可以有多种形式。它们不可避免地包含了对研究的积极记忆,这些研究提高了我们对当时问题的认识。它们也可以反映死胡同和失望。尽管农村发展研究通常是一项公共事业(政府、大学和非政府组织支持的项目),但研究人员所感受到的影响往往是个人的。在田间会见农民,倾听受虐待的农场妇女,追踪生计转变,这些都是对研究者的挑战。最重要的是,将研究成果用于政策制定是一项艰巨的任务,因为研究者和决策者之间存在多层稀释和偏转。考虑到这些障碍和机遇,我将以一篇评论文章的形式,就过去50年的农村发展研究提出一些自己的看法。本文分为三个部分:宏观和微观层面观察农村发展的演变和普遍趋势,第三部分是当代和未来问题。

Academia and government often ignore or deny the impact of population growth on the environment. However, key scientific institutions and reports confirm that population growth is a major driver of climate disruption and other environmental crises. We review the environmental science of population growth. Issues that block dialogue are discussed, such as growthism, anthropocentrism, denial, religious and cultural taboos, fear of being called a racist, the issue of rights claims, seeking political power through numbers, the framing of social justice issues, and sophistical claims regarding ‘racism’. We examine examples of denial about population in academia and government. We explore ways forward to gain dialogue, and we also consider success stories. We conclude that population growth, like overconsumption, must be foregrounded to create ecologocally sustainable economies and a sustainable future.
学术界和政府经常忽视或否认人口增长对环境的影响。然而,重要的科学机构和报告证实,人口增长是气候破坏和其他环境危机的主要驱动因素。我们回顾了人口增长的环境科学。讨论了阻碍对话的问题,如成长主义,人类中心主义,否认,宗教和文化禁忌,害怕被称为种族主义者,权利要求问题,通过数字寻求政治权力,社会正义问题的框架,以及关于“种族主义”的诡辩主张。我们研究了学术界和政府否认人口问题的例子。我们探讨对话的途径,我们也考虑成功案例。我们的结论是,必须重视人口增长,就像过度消费一样,以创造生态可持续的经济和可持续的未来。

Comparative Evidence on Corporate Governance Outcomes in the G20 Countries 二十国集团国家公司治理成果的比较证据
Pub Date : 2022-12-01 DOI: 10.3390/world3040056
V. Dragomir
The purpose of this study is to investigate the differences between developed countries in terms of corporate governance outcomes at aggregate and granular levels. The population of companies was collected from the database curated by Refinitiv. The sample was selected according to two criteria: the existence of governance scores for the financial year 2021 and the registration of a company in any of the G20 countries or the European Union. The results are presented by ranking the G20 countries based on four aggregate indicators and four granular indicators of corporate governance quality. While the differences regarding the aggregate indicators are not statistically strong, the intercountry differences on board independence, board gender diversity, board skills, and auditor tenure are especially relevant. The present article opens an avenue of research on international corporate governance linked to cultural dimensions, comparative legal systems, national approach to corporate social responsibility, and corporate governance principles.
本研究的目的是探讨发达国家在公司治理结果方面在总体和颗粒层面的差异。公司数量是从Refinitiv管理的数据库中收集的。样本是根据两个标准选择的:2021财年是否存在治理得分,以及公司是否在20国集团(G20)或欧盟(eu)中的任何一个国家注册。结果是根据公司治理质量的四个总体指标和四个颗粒指标对G20国家进行排名。虽然总体指标的差异在统计上并不明显,但在董事会独立性、董事会性别多样性、董事会技能和审计师任期方面的国家间差异尤为相关。本文开辟了一条研究国际公司治理的途径,将其与文化维度、比较法律制度、企业社会责任的国家方法和公司治理原则联系起来。

Afghanistan is a vulnerable country, and various challenges have led to widespread poverty. This study measured the different dimensions of poverty in rural and urban areas to help policymakers with poverty alleviation in the Kunduz province of Afghanistan. The data were collected from 360 rural and urban households. According to the findings, the MPI index in the Kunduz province’s rural and urban areas was found to be 0.483 and 0.445, respectively. The results indicate that Kunduz faces both rural and urban poverty, but that rural poverty is more severe than urban poverty. The intensity and headcount ratio of poverty in rural areas is more significant than in urban areas. It also is clear that all dimensions of poverty in Kunduz are very serious. Thus, it is necessary to establish a comprehensive program to reduce all aspects of poverty.
阿富汗是一个脆弱的国家,各种挑战导致了普遍的贫困。这项研究测量了农村和城市地区贫困的不同维度,以帮助阿富汗昆都士省的政策制定者减轻贫困。这些数据来自360个农村和城市家庭。根据研究结果,昆都士省农村和城市地区的MPI指数分别为0.483和0.445。结果表明,昆都士既面临农村贫困,也面临城市贫困,但农村贫困比城市贫困更严重。农村地区的贫困强度和人口比例比城市地区更为显著。同样明显的是,昆都士的贫困在各个方面都非常严重。因此,有必要建立一个全面的方案来减少贫困的各个方面。
