Community Health Services, Market Access, and Food Insecurity: Evidence From Ghana

open access: yesFood and Energy Security
The role of community interventions such as market infrastructure and health campaigns on household welfare are increasingly gaining attention of policymakers as they seek to identify pathways to achieve the sustainable development goals (SDGs) one, two,

Capsicum chinense as an African traditional vegetable: Culture, resilience, and opportunity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Capsicum chinense is central to everyday diets, cultural identity, and smallholder livelihoods across Sub‐Saharan Africa, yet remains overlooked in agricultural research and policy. This paper reframes C. chinense as a traditional, climate‐resilient vegetable shaped by centuries of farmer stewardship and cultural selection.

Brazil seed transfer zones: Supporting seed sourcing for climate‐resilient ecosystem restoration

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Brazil has tens of millions of hectares of degraded land that must be restored to meet national and global biodiversity and climate goals. Sowing genetically diverse native seeds is key to restoring degraded lands to climate‐resilient landscapes, but we still lack guidance on how to effectively match seed sources to restoration sites across broad ...

Peri‐urban agroforestry for climate mitigation in West Africa: Structural diversity and functional traits as key drivers of carbon storage

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Peri‐urban areas in West Africa are expanding rapidly, often with limited planning and growing exposure to climate risks. Our study shows that agroforestry systems in these landscapes, especially diverse home gardens, can store substantial amounts of carbon when they include structurally complex stands and species with traits that favor biomass ...

Recovery of rangelands : the functioning of soil seed banks in a semi-arid African savanna [PDF]

open access: yes, 2011
Rangelands in Africa provide important forage resources for herbivores; particularly perennial grasses provide grazing for domestic and wild herbivores.

Grass species and climatic season impact on Rhipicephalus microplus temporal abundance in a tropical region

open access: yesPest Management Science, EarlyView.
The interaction between grass species and climatic season shapes the population dynamics of the cattle tick, Rhipicephalus microplus. This information highlights the potential of forage species to influence off‐host tick dynamics. Additionally, minimum temperature and minimum relative humidity were the most influential microclimatic predictors of ...

On the evolutionary stability of the Uruguayan Savanna [PDF]

open access: yes
Tropical and subtropical grasslands have been the single-most valuable resource throughout the course of human evolution, and, to this point, despite fundamental errors associated with economic theory which suggest otherwise, these rangelands remain ...

Evaluating anisotropy‐based Monin–Obukhov similarity theory over canopies and complex terrain

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study shows that an anisotropy‐based generalization of Monin–Obukhov surface‐layer scaling (SC23) applies readily across a wide range of atmospheric conditions with variable terrain, canopies, and land‐cover complexity. This work focuses on the scaling of velocity variances for 7 years at the 47 sites in the National Ecological Observation Network

Savanna country [PDF]

open access: yes, 1976
savanna nTo the west only, beyond the head of the steady we caught glimpses of a level prairie land of vast green tracts like cultivated fields. This is the Savanna country so enthusiastically described by W.E.Cormack in his itinerary of 1822.DNE ...

Large‐scale characterization of horizontal forest structure from remote sensing optical images

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Sub‐meter resolution remote sensing data and tree crown segmentation techniques hold promise in offering detailed information that can support the characterization of forest structure from a horizontal perspective, offering new insights in the tree crown structure at scale.
