Assessing the adoption of high-iron bean varieties and their impact on iron intakes and other livelihood outcomes in Rwanda: Main survey report
An impact assessment (IA) study was conducted in Season B 20152 to establish the reach of high-iron bean (HIB) varieties to Rwandan bean farmers since these varieties were released in 2010, and to understand the adoption and diffusion patterns that have occurred so far. The IA was carried out in two parts. The first part was a listing survey, which was conducted at the beginning of Season B 2015, during the planting period. A total of 19,575 households were enlisted in 120 randomly selected villages throughout the country, and 93 percent of those households were bean-producing households. The listing exercise revealed that 28 percent of bean farmers had grown at least one HIB variety in at l...
Smallholder farming and crop variety choice
Zinc is an important nutrient for human health, especially for the growth of children (Caulfield and Black 2004). In 2011 Pakistans National Nutrition Survey found that zinc deficiency is high (47 percent) among children under-five years of age and women of child-bearing age. Nearly 42 percent of non-pregnant women, 48 percent of pregnant women, and 37 percent of children are estimated to be zinc deficient.
A technical review of modern cassava technology adoption in Nigeria (1985-2013)
In recent times, results of various adoption studies have been mixed, raising questions regarding why some improved farm technologies are still not widely adopted several years after their first introduction. Many improved cassava varieties have been introduced to millions of farm households across Africa south of the Sahara. Using an extensive review of cassava-adoption literature focused on Nigeria, this paper discusses the uptake of improved cassava varieties. Generic measurement and methodological issues in the literature are illuminated and alternative approaches suggested. The literature can be improved to better inform policy by considering issues such as attribution constraint due to...
Assessing the adoption of improved bean varieties in Rwanda and the role of varietal attributes in adoption decisions
Beans are grown by nearly all rural households in Rwanda, provide a large share of calorie intakes, and are a vital source of proteins and micronutrients. Because of the importance of this crop, significant research efforts have been devoted to select, breed, and disseminate bean varieties with superior production, consumption, and market attributes, while addressing challenges related to climate changes and food insecurity. As a result, nearly 100 bean varieties have been released in Rwanda over the last four decades. This study aims at documenting this effort; it assesses adoption of improved bush and climbing bean varieties, identifies determinants of and barriers to adoption, and analyze...
Assessing the Adoption of High Iron Bean Varieties and Their Impact on Iron Intakes and Other Livelihood Outcomes in Rwanda
An impact assessment (IA) study was conducted in Rwanda in 2015 Season B in order to establish the adoption rates of HIB varieties among rural bean producing and to generate useful information on delivery and breeding efforts by analyzing the facilitating/hindering factors to adoption and diffusion of HIB varieties. A nationally representative listing exercise preceded the main household survey for the impact assessment. The listing exercise was conducted across 120 rural villages in 29 provinces of Rwanda and was administered to a total of 19,575 households. The aims of the listing exercise were to determine the adoption rate of High Iron Beans (HIBs) and to inform second-stage sampling for the main impact assessment survey that was to follow. This report presents results from the listing exercise.
Smallholder farming and crop variety choice
Micronutrient deficiency, especially vitamin A deficiency, is a major problem in developing countries (Aguayo and Baker 2005; Black et al. 2008; Kennedy et al. 2003). Various strategies have been developed to combat vitamin A deficiency, including vitamin A supplementation (in the form of capsules), food fortification, and the promotion of household vegetable gardens. In Zambia, where more than half of preschool children are at risk for vitamin A deficiency (Micronutrient Initiative 2009), biannual capsules are provided to children in combination with vaccinations, and sugar is fortified with retinol, the pure form of vitamin A (Fiedler et al. 2013). Unfortunately, rural households are harder to reach with supplementation, and they do not consume many of the fortified processed foods.
Journalism in the Generation Z Age
This book examines how Generation Z, defined by their orientation as “social media natives,” grew up in a media system centered around social media. D. Jasun Carr and Mitchell T. Bard explore how Gen Z consumes news media differently than other cohorts, and how this shift in consumption affects both the members of Gen Z, the media, and media scholarship. The authors take a media ecology approach to laying out the new media landscape in which Gen Z was raised, before looking at how this new ecology affects many of the traditional theories and underpinnings of media effects, media psychology, and journalism. Through the use of original experimental research and the compilation of extant theory and survey data, Carr and Bard argue that while members of Gen Z eschew the more traditional structures of the media ecosystem in favor of those that incorporate a social element, they nevertheless behave, in many ways, similarly to those who came before. Scholars of communication, media studies, social media, and journalism will find this book of particular interest.
Crop Improvement, Adoption and Impact of Improved Varieties in Food Crops in Sub-Saharan Africa
Following on from the CGIAR study by Evenson and Gollin (published by CABI in 2003), this volume provides up-to-date estimates of adoption outcomes and productivity impacts of crop variety improvement research in sub-Saharan Africa. The book reports on the results of the DIIVA Project that focussed on the varietal generation, adoption and impact for 20 food crops in 30 countries. It also compares adoption outcomes in sub-Saharan Africa to those in South Asia, and guides future efforts for global agricultural research
