Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems

Oikos, EarlyView.
Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.

The example of the Nigerian savanna [PDF]

, 2006
In Nigeria terrace agriculture can mainly be found in the so called "Middle Belt Economy" as FORDE (1946)1 coined this type which lies between the grain economy of males in the north and tuber cultivation of females in the south.

Bushmeat consumption frequency and preferences among rural households in a West African savanna landscape: Implications for food security and conservation

People and Nature, EarlyView.
Abstract The drivers of consumer demand for bushmeat are relatively well studied in tropical forest systems, but much less so in savanna areas. This is important because differing ecological and socio‐economic conditions lead to different factors affecting the relationship between local communities and their natural resources.

Pyramiding aphid resistance genes into the elite cowpea variety, Zaayura, using marker-assisted backcrossing

Heliyon
The cowpea aphid (Aphis cracivora) is a cosmopolitan insect pest that causes economic damage on cowpea. Although the pest persists at all the growth stages of the crop, in West Africa, aphids are the only major insect pests that farmers regularly control

Could large‐scale silicon supplementation of crop‐lands mitigate the impacts of climate change?

PLANTS, PEOPLE, PLANET, EarlyView.
Intervention strategies that involve supplementing crop‐lands with silicon have significant scope for carbon capture and drought mitigation, offering wide‐ranging societal impacts. These include contributing to decarbonisation goals, enhancing food security, providing economic benefits and reducing environmental damage associated with intensive ...

International Savanna Fire Management Initiative

Biodiversidade Brasileira, 2019
Due to colonisation, traditional ways of fire management have been suppressed across landscapes and as a result vast areas of country are poorly managed and degraded. Conventional methods of firefighting have largely failed. Climate change will make the

Spatial carbon, nitrogen and phosphorus budget of a village territory in the West African savanna : I. Element pools and structure of a mixed-farming system [PDF]

, 2004
La viabilité des systèmes agropastoraux de savane ouest-africaine dépend largement de la gestion des ressources organiques endogènes car celles-ci satisfont les besoins locaux en nourriture, en fourrage et en bois, et maintiennent la qualité du sol.

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

PLANTS, PEOPLE, PLANET, EarlyView.
Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased
