TL;DR: In this article, the promotion of conservation agriculture (CA) in smallholder farming systems in sub-Saharan Africa is discussed, where the authors identify the situations for where CA (and which form of CA) is appropriate and make recommendations where research is required to address key knowledge gaps.

TL;DR: In this article, the authors compare experiences with conservation agriculture from the tropical Cerrado region of Brazil and from temperate conditions of Europe, focusing on agronomic performances, environmental impacts and economical results.

TL;DR: In this article, the impact of surface crop residue on water use and production risk associated with rainfall variability is analyzed for two contrasting tropical sites, La Tinaja in semi-arid Mexico and Planaltina in humid Brazil.

TL;DR: In this paper, the authors assessed yield gaps of main staple rainfed crops across contrasting family farming systems in Senegal (millet, subsistence oriented systems), central Brazil (maize, market oriented systems) and Vietnam (machinery, upland rice, subsistence-oriented systems) in 2-3 agricultural seasons in a network of farmers' fields, covering the diversity of soils and farmers' management practices.

TL;DR: In this paper, the relative effects of surface crop residue levels on the performance of a set of agro-ecological functions compared with a no-till bare soil were studied.
