Workers in Brazil and the United States have followed parallel and entangled histories for many centuries. Recent experiences with progressive, popular presidents and authoritarian, populist presidents in the two most populous countries in the hemisphere have underscored important similarities. The contributors in this volume focus on the comparative and transnational histories of labor between and across Brazil and the United States. The countries' histories bear the marks of slavery, racism, transoceanic immigration, and rapid urbanization, as well as strong regional differentiation and inequalities. These features decisively shaped the working classes. Brazilian and US labor history debates have erupted and subsided at different times. This collection synthesizes those debates while adding new topics and new sources from both countries. The international group of historians' methodologically innovative chapters explore links, resonances, and divergences between US and Brazilian labor history. They widen the scope of analysis for themes and problems that have long been familiar to historians of work and workers in the two countries, but have not provoked close dialogues between scholars in the respective places. Though the histories themselves were often entangled, the debates about them have too rarely intertwined.

This collection features five peer-reviewed reviews on weed management in regenerative agriculture. The first chapter provides an analytical review of the adoption of Conservation Agriculture (CA) in Sub-Saharan Africa by smallholder farmers, focusing on the challenges posed by weed management. The chapter assesses chemical and non-chemical weed control methods and their benefits in CA systems. The second chapter considers the adoption of integrated weed management (IWM) in organic cropping systems, focussing on the key challenges that can arise as a result of this adoption. It also presents examples of successful integration between preventive, cultural and direct tactics in an IWM strategy. The third chapter highlights an increasing need for IWM strategies in the face of herbicide-resistant weeds, soil degradation and environmental contamination by herbicides. The chapter reviews the cultural techniques available to manage weeds in a sustainable manner. The fourth chapter introduces the concept of using crop rotations and cover crops as an effective and sustainable strategy for controlling weeds and looks ahead to future research in this area. The final chapter utilises four detailed case studies from across Europe to illustrate the effectiveness of combined methods to control weeds and preserve/improve farmers’ income.
