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...
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.
The State of Food and Agriculture 2020
Intensifying water constraints threaten food security and nutrition. Thus, urgent action is needed to make water use in agriculture more sustainable and equitable. Irrigated agriculture remains by far the largest user of freshwater, but scarcity of freshwater is a growing problem owing to increasing demand and competition for freshwater resources. At the same time, rainfed agriculture is facing increasing precipitation variability driven by climate change. These trends will exacerbate disputes among water users and inequality in access to water, especially for small-scale farmers, the rural poor and other vulnerable populations. The State of Food and Agriculture 2020 presents new estimates o...
La situation mondiale de l’alimentation et de l’agriculture 2020
Les contraintes croissantes qui pèsent sur l’eau menacent la sécurité alimentaire et la nutrition. Il faut agir d’urgence pour que l’eau utilisée dans l’agriculture le soit de façon plus durable et plus équitable. L’agriculture irriguée reste de loin le principal utilisateur des ressources en eau douce, mais ces ressources font l’objet d’une demande croissante et d’une concurrence accrue qui créent des situations de rareté de plus en plus préoccupantes. L’agriculture pluviale, confrontée à la variabilité des précipitations sous l’effet du changement climatique, n’est pas non plus épargnée. Ces tendances ne feront qu’exacerber les conflits entre les div...
2020年粮食及农业状况
愈演愈烈的缺水问题对粮食安全和营养构成威胁。因此，迫切需要采取行动，在农业生产中更可持续、更公平地利用水资源。灌溉农业依然是淡水资源的最大用户，但随着对淡水资源的需求和竞争不断升级，淡水资源短缺问题正日益加重。同时，雨养农业正面临气候变化带来的降雨波动幅度不断加大的问题。这些趋势将加剧水资源使用者之间的矛盾纠纷和水资源获取方面的不平等，尤其对小农、农村贫困人口及其他弱势群体而言。《2020年粮食及农业状况》就灌溉农业中普遍存在的水资源短缺问题、雨养农业中普遍存在的水资...
2020 حالة الأغذية والزراعة
إنّ القيود المكثّفة المتصلة بالمياه تهدّد الأمن الغذائي والتغذية. وبالتالي، ثمة حاجة ملحّة إلى اتخاذ الإجراءات اللازمة لجعل استخدام المياه في الزراعة مستدامًا ومنصفًا على نحو أكبر. ومع أنّ الزراعة المروية لا تزال أكبر القطاعات المستخدمة للمياه العذبة على الإطلاق، إلا أن ندرة المياه العذبة تطرح مشكلة تتفاقم أكثر فأكثر بسبب تزايد الطلب والمنافسة على موارد المياه العذبة. وفي الوقت ...
El estado mundial de la agricultura y la alimentación 2020
Limitaciones cada vez mayores del abastecimiento hídrico amenazan la seguridad alimentaria y la nutrición. Por consiguiente, se hace necesario actuar con urgencia a fin de lograr un uso más sostenible y equitativo del agua en la agricultura. La producción agrícola de regadío sigue siendo, de lejos, el principal usuario de agua dulce, pero la escasez de este recurso constituye un problema cada vez mayor debido al incremento de la demanda y a la competencia por su utilización. Al mismo tiempo, la agricultura de secano se enfrenta a la creciente variabilidad de las precipitaciones como consecuencia del cambio climático. Estas tendencias exacerbarán las disputas entre usuarios del agua ...
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...

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
