Chronic undernutrition is characterized by long-term exposure to food of insufficient quality and inadequate quantity, including restricted intake of energy, protein, fat, micronutrients, essential amino acids, vitamins and minerals. Physiologically, in a state of chronic food insufficiency, the human body conserves energy by prioritizing essential metabolic processes resulting in impaired linear growth and delayed reproductive maturation. Consequently, height can theoretically be considered a measure of an individual’s cumulative health and nutrition. Therefore, a deviation from the ‘normal’ height relative to one’s age represents a deviation from one’s optimal growth and, potentially, the presence of other issues. Similarly, the delayed onset of puberty is another common physiological response to food insufficiency, often accompanying impaired linear growth. Chronic undernutrition can arise from chronic disease, congenital abnormalities and insufficient food intake. In this review, we will explore the hypothesis of CUG during adolescence, given the relationship between impaired linear growth and the delayed onset of puberty in children suffering from chronic undernutrition due to a lack of sufficient quality and quantity of food.

Geospatial technologies have transformed the way we visualize and understand social phenomena and physical environments. There are significant advantages in using these technologies and data however, their use also presents ethical dilemmas such as privacy and security concerns as well as the potential for stigma and discrimination resulting from being associated with particular locations. Therefore, the use of geospatial technologies and resulting data needs to be critically assessed through an ethical lens prior to implementation of programmes, analyses or partnerships. This paper examines the benefits, risks and ethical considerations when undertaking evidence generation using geospatial technologies. It is supplemented by a checklist that may be used as a practical tool to support reflection on the ethical use of geospatial technologies.
Geospatial technologies have transformed the way we visualize and understand situations. They are used to acquire, manipulate, store and visualize geographical information, including information on where individuals, groups and infrastructure are located in time and space. For development and humanitarian based organizations like UNICEF, the value of these technologies includes the ability to collect and process real-time information from places that are hard to reach or navigate such as dense forest, conflict zones, or where environmental disasters are occurring or have occurred. This brief provides an overview of the critical considerations when undertaking evidence generation using geospatial technologies. It is supplemented by a checklist that may be used to support reflection on the ethical use of geospatial technologies. This brief is based on a more in-depth Innocenti Discussion Paper which provides further guidance and tools.
There are significant ethical implications in the adoption of technologies and the production and use of the resulting data for evidence generation. The potential benefits and opportunities need to be understood in conjunction with the potential risks and challenges. When using social media to directly engage children and their communities, or when establishing partnerships with these organizations for data collection and analysis, adoption of these technologies and their resultant data should not be exclusively driven by short-term necessity but also by the long-term needs of our younger partners. When engaging with social media and indeed most technology, thoughtfulness, reflection and ongoing interrogation is required. This paper examines the benefits, risks and ethical considerations when undertaking evidence generation: (a) using social media platforms and (b) using third-party data collected and analysed by social media services. It is supplemented by practical tools to support reflection on the ethical use of social media platforms and social media data.
As of January 2017, 2.78 billion people worldwide were classified as active social media users. Of these users, 1.87 billion use Facebook. Thirty-nine per cent of Facebook users are between the ages of 13 and 24 (approximately 729 million young people). Available data also show that in 2014, approximately 31 per cent of users of the top five social media platforms were aged between 16 and 24 years. With the enormity of this coverage as well as over 40 per cent growth in usage from the previous year in countries like India, UNICEF has and continues to look at ways to use these platforms and the data generated to connect with and understand the reality of children today and to ensure more child-centred/user-centred policies and services. This brief provides an overview of the critical ethical considerations when undertaking evidence generation using social media platforms and using third-party data collected and analysed by social media services. It is supplemented by checklists that may be used to support reflection on the ethical use of social media platforms and social media data. This brief is based on a more in-depth Innocenti Discussion Paper which provides further guidance and tools.
A recent strand of aid programming aims to develop household assets by removing the stresses associated with meeting basic nutritional needs. In this paper, we posit that such programmes can also boost nutrition in recipient households by encouraging further investment in diet. To test this hypothesis, we study the World Food Programme’s “Protracted Relief and Recovery Operation (PRRO)” in Niger, a conflict-affected, low income country with a high share of malnourishment. Under PRRO, a household could be in one of three groups at endline: receiving food aid to prevent malnutrition, receiving both preventive food aid and food for assets assistance, or receiving no assistance (the control group). When provided only by itself, the food aid has no nutritional impact, relative to receiving no assistance. However, we observe pronounced positive effects when preventive food aid is paired with assets-based programming, over and above what stems from greater household assets. We conclude, first, that certain forms of food aid function well in complex, insecure environments; second, that assets-based programmes deliver positive nutritional spillovers; and, third, that there are theoretical grounds to believe that asset-based programmes interact positively with more nutrition-focussed programming.

In 2016, approximately 815 million people were chronically undernourished globally. In recent years, food security has worsened in some parts of the world, including sub-Saharan Africa. In Zimbabwe, latest estimates show that about 45% of the total population are undernourished1. To address the challenge of growing food insecurity, effective social protection programmes must be implemented and scaled-up. Cash transfers are one such programme, the primary objectives of which often include poverty alleviation and food insecurity reduction. This research study utilized longitudinal data collected for the impact evaluation of Zimbabwe’s Harmonized Social Cash Transfer Programme (HSCT), an unconditional cash transfer that targets ultra- poor, labour-constrained households. It accomplishes two things: It provides evidence on the relative merits of using an aggregate consumption expenditure measure versus a food security scale, to assess household vulnerability and food insecurity; and it contributes to a growing literature on the effects of state-sponsored unconditional cash transfers in Africa on household behaviour and food security.
A pre-post study examining the effectiveness of a parenting support programme in the Eastern Cape, South Africa, showed reductions in child abuse, child delinquency, parent and child depression, parenting stress and substance use. It also showed improvements in parental supervision, positive parenting and social support. In addition to the pre-post study, a qualitative enquiry was conducted with the programme facilitators. This paper explores the experiences and perception of local child and youth care workers, who were trained to deliver the parenting programme in vulnerable, semi-rural communities. The purpose of this publication is to make recommendations on how to improve the programme for scale-up, in South Africa and beyond.
In 2016, UNICEF hosted The Adolescent Brain: A second window of opportunity, a symposium that brought together experts in adolescent neuroscience to discuss this emerging science and how we can apply it to support all adolescents – but especially those already facing risks to their well-being, including poverty, deprivation, conflict and crisis. The articles in this compendium elaborate on some of the ideas shared at the symposium. Together, they provide a broad view of the dynamic interactions among physical, sexual and brain development that take place during adolescence. They highlight some of the risks to optimal development – including toxic stress, which can interfere with the formation of brain connections, and other vulnerabilities unique to the onset of puberty and independence. They also point to the opportunities for developing interventions that can build on earlier investments in child development – consolidating gains and even offsetting the effects of deficits and traumas experienced earlier in childhood.
