Frequent burning promotes invasions of alien plants into a mesic African savanna [PDF]
, 2010 Fire is both inevitable and necessary for maintaining the structure and functioning of mesic savannas. Without disturbances such as fire and herbivory, tree cover can increase at the expense of grass cover and over time dominate mesic savannas ...

Genetic control of earliness in cowpea (Vigna unguiculata (L) Walp)
Heliyon, 2022 Global climate change is expected to further intensify the already harsh conditions in the dry savannah ecological zones of sub-Saharan Africa, posing serious threats to food and income security of millions of smallholder farmers.

Rootzone storage capacity reveals drought coping strategies along rainforest-savanna transitions
Environmental Research Letters, 2020 Climate change and deforestation have increased the risk of drought-induced forest-to-savanna transitions across the tropics and subtropics. However, the present understanding of forest-savanna transitions is generally focused on the influence of ...

The biodiversity cost of carbon sequestration in tropical savanna
Science Advances, 2017 Forest expansion into Brazilian savanna due to fire suppression causes precipitous species loss. Tropical savannas have been increasingly viewed as an opportunity for carbon sequestration through fire suppression and afforestation, but insufficient ...

Performance of maize populations under different nitrogen rates in northern Ghana
Annals of Agricultural Sciences, 2018 This study evaluated grain yield performance, stability and agronomic nitrogen-use efficiency (AE) of twelve maize populations under three nitrogen (N) rates at two locations in the Guinea and Sudan savannah zones of Ghana in 2014 and 2015.
