Einfluss von HTC-Biokohle als Bodenverbesserer auf den Wachstums- und Entwicklungsverlauf bei Sojabohnen

The influence of biochar with an amount of 0 to 20 t/ha on growth, yield and ingredients on soybeans of different variants was compared. Differences between the variants until blooming could be found. Plants from the HTC variant have shown significantly longer stems than others. These differences diminished until the harvest. Due to extrem low precipitation values in spring and early summer, no rhizobia could be developed and nitrogen fixation for the soybean was impossible. The plants could only use nitrogen from the soil. As a result, plots prepared with mineral fertilizer have shown the significantly longest plants, highest mass of dry matter and highest yields. Further, HTC variants have shown the lowest values in oil- and sugar contents. The highest value in sugar content was measured in the variant with mineral fertilizer, but did not differ significantly. This results show, that due to the lower amount of available nitrogen in the year of application there can be a negative influence of biochar on the yield

Combining preschool teacher training with parenting education : a cluster-randomized controlled trial

This paper evaluates a government program in Malawi, which aimed to improve quality at community-based childcare centers and complemented these efforts with a group-based parenting support program. Children in the integrated intervention arm (teacher training and parenting) had significantly higher scores in measures of language and socio-emotional development than children in centers receiving teacher training alone at the 18-month follow-up. However, the study finds no effects on child assessments at the 36-month follow-up. Significant improvements at the centers relating to classroom organization and teacher behavior in the teacher-training only arm did not translate into improvements in child outcomes at either follow-up. The findings suggest that, in resource-poor settings with informal preschools, programs that integrate parenting support within preschools may be more effective than programs that simply improve classroom quality

A Toolkit for Measuring Early Childhood Development in Low and Middle-Income Countries

The Toolkit provides a practical, “how-to” guide for selection and adaptation of child development measurements for use in low- and middle-income countries. Users can follow the proposed step-by-step process to select, adapt, implement, and analyze early childhood development data for diverse purposes and projects. Researchers, evaluators, and program personnel from various disciplines interested in assessing early childhood development in low- and middle-income countries will find the book useful for planning and evaluating interventions, monitoring development over time, or conducting a situation analysis. The book updates and expands a previous 2009 edition, incorporating new research on the use of child development measurement tools in low- and middle-income countries. The ECD Measurement Inventory that accompanies this Toolkit contains 147 measurement tools for children under 8 years. For each test it reports the domains assessed, age range for which the tool is appropriate, method of administration, purpose of the assessment, origin and locations of use, logistics, and cost

Multilingual assessment of early child development: Analyses from repeated observations of children in Kenya.

In many low- and middle-income countries, young children learn a mother tongue or indigenous language at home before entering the formal education system where they will need to understand and speak a countrys official language(s). Thus, assessments of children before school age, conducted in a nations official language, may not fully reflect a childs development, underscoring the importance of test translation and adaptation. To examine differences in vocabulary development by language of assessment, we adapted and validated instruments to measure developmental outcomes, including expressive and receptive vocabulary. We assessed 505 2-to-6-year-old children in rural communities in Western Kenya with comparable vocabulary tests in three languages: Luo (the local language or mother tongue), Swahili, and English (official languages) at two time points, 5-6 weeks apart, between September 2015 and October 2016. Younger children responded to the expressive vocabulary measure exclusively in Luo (44%-59% of 2-to-4-year-olds) much more frequently than did older children (20%-21% of 5-to-6-year-olds). Baseline receptive vocabulary scores in Luo (β = 0.26, SE = 0.05, p < 0.001) and Swahili (β = 0.10, SE = 0.05, p = 0.032) were strongly associated with receptive vocabulary in English at follow-up, even after controlling for English vocabulary at baseline. Parental Luo literacy at baseline (β = 0.11, SE = 0.05, p = 0.045) was associated with child English vocabulary at follow-up, while parental English literacy at baseline was not. Our findings suggest that multilingual testing is essential to understanding the developmental environment and cognitive growth of multilingual children

Improving child nutrition and development through community-based childcare centres in Malawi - The NEEP-IE study: study protocol for a randomised controlled trial

Abstract Background The Nutrition Embedded Evaluation Programme Impact Evaluation (NEEP-IE) study is a cluster randomised controlled trial designed to evaluate the impact of a childcare centre-based integrated nutritional and agricultural intervention on the diets, nutrition and development of young children in Malawi. The intervention includes activities to improve nutritious food production and training/behaviour-change communication to improve food intake, care and hygiene practices. This paper presents the rationale and study design for this randomised control trial. Methods Sixty community-based childcare centres (CBCCs) in rural communities around Zomba district, Malawi, were randomised to either (1) a control group where children were attending CBCCs supported by Save the Children’s Early Childhood Health and Development (ECD) programme, or (2) an intervention group where nutritional and agricultural support activities were provided alongside the routine provision of the Save the Children’s ECD programme. Primary outcomes at child level include dietary intake (measured through 24-h recall), whilst secondary outcomes include child development (Malawi Development Assessment Tool (MDAT)) and nutritional status (anthropometric measurements). At household level, primary outcomes include smallholder farmer production output and crop-mix (recall of last production season). Intermediate outcomes along theorised agricultural and nutritional pathways were measured. During this trial, we will follow a mixed-methods approach and undertake child-, household-, CBCC- and market-level surveys and assessments as well as in-depth interviews and focus group discussions with project stakeholders. Discussion Assessing the simultaneous impact of preschool meals on diets, nutrition, child development and agriculture is a complex undertaking. This study is the first to explicitly examine, from a food systems perspective, the impact of a preschool meals programme on dietary choices, alongside outcomes in the nutritional, child development and agricultural domains. The findings of this evaluation will provide evidence to support policymakers in the scale-up of national programmes. Trial registration ISRCTN registry, ID: ISRCTN96497560 .

Indicators of Family Care for Development for Use in Multicountry Surveys

Indicators of family care for development are essential for ascertaining whether families are providing their children with an environment that leads to positive developmental outcomes. This project aimed to develop indicators from a set of items, measuring family care practices and resources important for caregiving, for use in epidemiologic surveys in developing countries. A mixed method (quantitative and qualitative) design was used for item selection and evaluation. Qualitative and quantitative analyses were conducted to examine the validity of candidate items in several country samples. Qualitative methods included the use of global expert panels to identify and evaluate the performance of each candidate item as well as in-country focus groups to test the content validity of the items. The quantitative methods included analyses of item-response distributions, using bivariate techniques. The selected items measured two family care practices (support for learning/stimulating environment and limit-setting techniques) and caregiving resources (adequacy of the alternate caregiver when the mother worked). Six play-activity items, indicative of support for learning/stimulating environment, were included in the core module of UNICEF\u2019s Multiple Cluster Indictor Survey 3. The other items were included in optional modules. This project provided, for the first time, a globally-relevant set of items for assessing family care practices and resources in epidemiological surveys. These items have multiple uses, including national monitoring and cross-country comparisons of the status of family care for development used globally. The obtained information will reinforce attention to efforts to improve the support for development of children

Cluster-randomised controlled trials of individual and combined water, sanitation, hygiene and nutritional interventions in rural Bangladesh and Kenya: the WASH Benefits study design and rationale.

INTRODUCTION: Enteric infections are common during the first years of life in low-income countries and contribute to growth faltering with long-term impairment of health and development. Water quality, sanitation, handwashing and nutritional interventions can independently reduce enteric infections and growth faltering. There is little evidence that directly compares the effects of these individual and combined interventions on diarrhoea and growth when delivered to infants and young children. The objective of the WASH Benefits study is to help fill this knowledge gap. METHODS AND ANALYSIS: WASH Benefits includes two cluster-randomised trials to assess improvements in water quality, sanitation, handwashing and child nutrition-alone and in combination-to rural households with pregnant women in Kenya and Bangladesh. Geographically matched clusters (groups of household compounds in Bangladesh and villages in Kenya) will be randomised to one of six intervention arms or control. Intervention arms include water quality, sanitation, handwashing, nutrition, combined water+sanitation+handwashing (WSH) and WSH+nutrition. The studies will enrol newborn children (N=5760 in Bangladesh and N=8000 in Kenya) and measure outcomes at 12 and 24 months after intervention delivery. Primary outcomes include child length-for-age Z-scores and caregiver-reported diarrhoea. Secondary outcomes include stunting prevalence, markers of environmental enteropathy and child development scores (verbal, motor and personal/social). We will estimate unadjusted and adjusted intention-to-treat effects using semiparametric estimators and permutation tests. ETHICS AND DISSEMINATION: Study protocols have been reviewed and approved by human subjects review boards at the University of California, Berkeley, Stanford University, the International Centre for Diarrheal Disease Research, Bangladesh, the Kenya Medical Research Institute, and Innovations for Poverty Action. Independent data safety monitoring boards in each country oversee the trials. This study is funded by a grant from the Bill & Melinda Gates Foundation to the University of California, Berkeley.

Care for Child Development in rural Malawi – a model feasibility and pilot study

Evidence demonstrates that encouraging stimulation, early communication, and nutrition improves child development. Detailed feasibility studies in real‐world situations in Africa are limited. We piloted Care for Child Development through six health surveillance assistants (HSAs) in group and individual sessions with 60 caregivers and children <2 years and assessed recruitment, frequency, timings, and quality of intervention. We collected baseline/endline anthropometric, child development (MDAT), maternal stress (SRQ), and family care indicators (FCIs) data and determined acceptability through 20 interviews with caregivers and HSAs. HSAs could only provide coverage on 14.2% of eligible children in their areas; 86% of group sessions and a mean of 3.6/12 individual sessions offered to mothers were completed. Pre‐ and post‐assessment of children demonstrated significant changes in MDAT language and social Z‐scores and FCIs. Caregivers perceived sessions as beneficial and HSAs good leaders but that they could be provided through other mechanisms. Integrated Care for Child Development programs for 0–2 years old are readily accepted in Malawi, but they are not feasible to conduct universally through HSAs due to limited coverage; other models need to be considered
