This book focuses on three important elements in the development of cereal and legume crops in semi-arid West Africa. The first section illustrates the socioeconomic factors that affect the food system for these crops and contains an overview of crop production and consumption in the region. Then, important inputs that affect system productivity are presented: preferences for new seed varieties, yield response to fertilizer, counterfeit herbicides, climate information, and the way farmers develop expectations about the weather events that shape cropping outcomes. The final chapter of section one is dedicated to understanding urban consumer preferences for processed food products derived …

Data and Datasets

We evaluated whether female or male bees were more abundant on sunflowers, whether female bees were more abundant on pollen-fertile or pollen-sterile sunflower cultivars, and whether the bee community differed between pollen-fertile and pollen-sterile sunflower cultivars. We further evaluated whether bee communities were shaped by local floral resources and landscape composition. We sampled bees visiting sunflowers (Helianthus spp.) from 14 farms in the Connecticut River Valley of western Massachusetts between 25 July to 27 September 2019, typically making two sampling visits to a farm. We also measured floral resource diversity and abundance at the farms, and categorized the landscape types …
