Effects of agroforestry and climate on cocoa yield, pests and diseases por Asitoakor, B.K.

“…The crop is cultivated across many tropical regions, with the largest production from West Africa, where Ghana and Cote d’Ivoire contribute 70% of global production. Two major systems dominate cocoa production; a full-sun monocropping system where the cocoa crop is grown without shade trees, and an agroforestry system where cocoa is grown with deliberately planted or retained forest/fruit trees. …”

Nitrogen and phosphorus uptake by maize as affected by particulate organic matter quality, soil characteristics, and landuse history for soils from the West African moist savanna z... por Vanlauwe, Bernard, Aihou, K., Tossah, S., Aman, B.K., Diels, J., Lyasse, O., Hauser, S., Sanginga, P., Merckx, Roel

“…After addition of all nutrients except P, the total maize P uptake was linearly related to the Olsen P content. R2 increased from 0.56 to 0.67 in a multiple linear regression analysis including the Olsen P content and clay content (which explained 11% of the variation in P uptake). …”

How are climate, security, and human mobility dynamics interrelated in Pakistan? por Khalid, Shahab, Savelli, Adam, Vaselli, Alessandra, Carneiro, Bia, Pacillo, Grazia, Laderach, Peter

“…This paper identifies three key pathways through which these drivers interact, often in non-linear and overlapping ways. The first pathway illustrates how climate-induced disruptions to land, water, and food systems—especially in the Indus Basin—intensify livelihood loss and social tensions, increasing the likelihood of conflict and displacement. …”
