Since the WHO officially declared the outbreak of COVID-19 as a global pandemic, governments across the world implemented strict lockdowns to contain its spread. Although vital in containing the virus, it caused massive ramifications to world economies, and small and medium enterprises (SMEs) have been one of the hardest-hit sectors. The case was no different for Bangladesh. In this study, we assess the economic impact of the pandemic on the SMEs in Bangladesh. We also assess the pandemic’s economic impact on a sample of youth, many of whom were employed in the SMEs during the pre-pandemic period.

Maize is a staple crop in many areas of the world. In Eastern and Southern Africa, maize is estimated to account for 22% of all calories consumed and is an important crop for subsistence farmers in the region (Shiferaw et al., 2011). A central challenge for policymakers concerned about food security is how to boost agricultural productivity in lower-income countries, where maize yields are a small fraction of the average in OECD countries (OECD/FAO, 2021). Increasing access to improved agricultural inputs such as high yielding seed varieties and fertilizers have been one focus among policymakers in recent decade (Evenson and Gollin, 2003). However, recently scholarly work and local media coverage has suggested that retail maize seeds in East Africa and other agricultural inputs are variable and often sub-standard (Bold et al., 2017; Ashour et al., 2019; Muchiri, 2019; Okinda, 2019). In Kenya, the regulation of agricultural inputs falls under the responsibility glmlicof the Kenya Plant Health Inspectorate Service (KEPHIS). A number of observable markers on seed packets help indicate that the packet has properly gone through KEPHIS certification procedures, as required under national regulations. For example, a printed lot number, a printed packaging or testing date, and an e-verification sticker help to communicate to the end-user (in this case the farmer) that a packet has been certified and is not expired.

The COVID-19 pandemic brought the dual crises of disease and the containment policies designed to mitigate it. There is little evidence on the impacts of these policies on women, who are likely to be especially vulnerable, in lower-income settings. We conduct a large phone survey and leverage India’s geographically-varying containment policies to estimate the association between both the pandemic and its containment policies, and measures of women’s well-being, including mental health and food security. The pandemic resulted in dramatic income losses, increases in food insecurity, and declines in female mental health. While potentially crucial for public health, containment policies are associated with greater food insecurity, particularly for women, and reduced female mental health. For women, average containment levels are associated with a 39-45% increase in the likelihood of sadness, depression, hopelessness, and feeling more worried. Vulnerable groups of women — those with daughters and those living in female-headed households — experience even larger declines in mental health.

The GEO for Business Brief titled ‘Future-proofing infrastructure for climate resilience’ published by the United Nations Environment Programme (UNEP) to better inform, engage and stimulate positive action from business leaders was launched at a successful event on 7 December 2021. The launch was webcast on YouTube as well as on LinkedIn Live and Zoom with the support of UNEP-WCMC and the UNEP Communication Team. The Business Brief’s launch took place through a high-level interactive panel discussion, including opening remarks from Ligia Noronha, UN Assistant Secretary-General and Head of UNEP, New York Office, she set the scene with a keynote statement that emphasized how crucial future-proofing infrastructure is in addressing the three planetary crises (climate change, nature and biodiversity loss, and pollution and waste) and achieving the SDGs. She stated further that “by future-proofing, infrastructure is flexible and resilient to risks such as those posed by climate change and environmental disasters, such as flooding or fires. Future-proof infrastructure also helps move us towards a circular, net-zero carbon future. This is even more important now, because between 1998 and 2017, climate-related disasters accounted for 91 per cent of all recorded disasters and this affected 2 billion people, mostly in Asia and Africa.

The COVID-19 pandemic affects people's psychological well-being as well as their risk of physical complications. Under the circumstance, it is essential to synthesize the existing evidence on psychological consequences with a view to fostering policymaking. Thus, a systematic attempt was compiled to review the Bangladeshi literature related to common mental health problems (i.e. depression, anxiety, and stress) during the COVID-19 pandemic. Adhering to the PRISMA guidelines, a systematic literature search was performed using Medline or PubMed, Scopus, PsycINFO, Web of Science, CINAHL, Google Scholar, PsyArxiv, MedRxiv, and ResearchGate, between 20 December 2020 and 5 March 2021, followed by predetermined eligibility criteria. The inclusion criteria for this review were observational studies involving at least one mental health problem (i.e. stress, depression, and anxiety) published in peer-reviewed journals or preprint servers in the English language after the inception of the pandemic in Bangladesh. The pooled prevalence of depression, anxiety, and stress was 47% (95% CI 39-55%, I 2 = 99.14%), 47% (95% CI 39-54%, I 2 = 99.78%), and 44% (95% CI 30-58%, I 2 = 99.36%), respectively. Subgroup analysis revealed that students were experiencing a higher rate of depression, anxiety, and stress than general people and healthcare professionals. The associated risk factors of mental health problems were gender, age, residence area, family size, monthly family income, educational status, marital status, physical exercise, smoking, alcohol use, fear of COVID-19, presence of chronic illness, unemployment status, and exposure to COVID-19-related news and social media. This systematic review provides baseline data on the symptoms of depression, anxiety, and stress across various Bangladeshi cohorts, which are anticipated to be helpful to the respective authorities for implementing cohort-specific mental health strategies.

Background: The sexual and reproductive health and rights (SRHR) of migrants and refugees present important public health challenges. Social and structural determinants affect both the general health and SRHR of migrants, but the drivers of SRHR among migrant and refugee populations remain understudied. Aims: To identify upstream social and structural determinants of SRHR health of migrants and refugees reported in systematic reviews. Methods: We conducted a systematic review of reviews. We studied 3 aspects of SRHR: sexually transmitted infections, sexual violence and unintended pregnancy in migrants and refugees. We used an inductive approach to synthesize emerging themes, summarized them in a narrative format and made an adapted version of Dahlgren and Whitehead's social determinants of health (SDH) model. Results: We included 12 systematic reviews, of which 10 were related to sexually transmitted infections, 4 to sexual violence and 2 to unintended pregnancy. We identified 6 themes that operate at 4 different levels in an adapted version of the Dahlgren and Whitehead SDH model: economic crisis and hostile discourse on migration; limited legal entitlements, rights and administrative barriers; inadequate resources and financial constraints; poor living and working conditions; cultural and linguistic barriers; and stigma and discrimination based on migration status, gender, sex and ethnicity. Conclusion: This review provides evidence of how upstream social and structural determinants undermine the SRHR of refugees and migrants. Unless these are addressed in policy-making and planning, the health of migrants and refugees is at risk.

Help us to shape a future that not only acknowledges but demonstrates how investing in nature-based solutions can address the multi-faceted environmental crises and broader societal challenges that affect humanity today. The purpose of this Open Call is to identify examples of investment models that contribute to nature-based solutions that could be replicated or scaled up by others around the globe. This open call is in addition to the ‘State of Finance for Nature – Open Call for Best Practices’ that was collected till February 19th, 2021. It is our intent that submissions to this open call can fill gaps from the prior submissions and update the database with new projects. Following the IUCN definition, investment in nature-based solutions (NbS) should be interpreted in a broader sense as capital flows that contribute positively to climate change mitigation, restoration and/or biodiversity conservation. Please submit your proposal through this form until April 30, 2022. We will group and select the content that will be featured on the State of Finance for Nature Hub as stories and podcasts among other content. The State of Finance for Nature Hub is a flagship database of the UN Environment Programme on worldwide efforts to catalyze public and private investments into nature that will be published in 2022. By filling out the form, you agree that your information will be made public. The working language is English. Should you have any questions, please contact Fiona Cromarty at fiona.cromarty@un.org.

Fresh on the heels of COP-26, UNEP Climate Finance Unit with UNEP-WCMC organised a series of knowledge exchange events that built upon its predecessors in 2019 and 2021 to discuss this gap, share challenges and find practical solutions. The three invite-only workshops and two open webinars spread over the week of November 29 to December 3, 2021, brought together different stakeholders operating in the sustainable land-use finance space. They brought attention to issues that are central to environmental and social risk management in investment or lending decisions. The workshops were aimed at building a shared understanding of aims, challenges and solutions in developing appropriate eligibility criteria, risk screening and due diligence processes. It was found that when setting the minimum bar or eligibility criteria, balancing between inclusion, financial returns and E&S impact is a major concern. Financial institutions should account for geographical and regional differences, from legal requirements to also accounting for smaller players who might face barriers in demonstrating compliance with high standards. Participants expressed that greater emphasis should be placed on transparency and progressive improvement with milestones, rather than strict compliance against some of the common eligibility criteria. Some specific aspects such as biodiversity and land tenure have remained difficult to assess in terms of risk and impact. This is particularly compounded by the lack of availability of integrated data and limited harmonization of methodologies to assess risk and impact as well as lack of capacity on such technical issues. The approach to risk screening and due diligence also varies considerably and depends on a number of factors such as how vertically integrated the funds/facilities are, the experience of the funds, risk appetite, target geography and investees, requirements from the investors in terms of compliance, and how concessionalized the funds/facilities are. Most financial institutions take a two-step approach to screening risk and conducting due diligence against risks identified as high. More often than not, for most fund managers the process of risk assessment and due diligence is a journey together with the investees where trust, data and transparency, capacity building are crucial elements. This series of workshops helped build a shared understanding of challenges and solutions. A summary and guidance document based on the outcomes of the webinars is currently under development and will be shared with the investment community in the coming months.
