Biodiversity Conservation in Tropical Agroecosystems
Ivette Perfecto,John Vandermeer +1 more
TL;DR: The new conservation paradigm should incorporate a landscape approach in which small farmers, through their social organizations, work with conservationists to create a landscape matrix dominated by productive agroecological systems that facilitate interpatch migration while promoting a sustainable and dignified livelihood for rural communities.
Home gardens: a promising approach to enhance household food security and wellbeing
TL;DR: In this paper, a review of the role of home gardening in crisis and post-crisis situations, as well as assessing their economic value and their impacts on food security, nutrition, economic growth, and gender issues is presented.

R. W. Willey,M. S. Reddy +1 more
TL;DR: In this paper, a field technique is described in which trenches were dug and vertical polythene partitions installed to eliminate below-ground interactions between component crops in intercropping, showing that the main determinant of yield advantage was an above-ground interaction between the canopies.
