Charting the Path to Increased Oil Palm Output in Ghana Beyond Area Expansion: Technology or Managerial Capacity — Which Leads the Way?

Agribusiness, EarlyView.
ABSTRACT This study sets out to investigate the prospects for raising oil palm output in sub‐Saharan Africa, particularly Ghana, without further expansion of cropland. Given global concerns about oil palm's role in deforestation and land use change, the focus is on enhancing productivity on existing farmlands.

Soil salinity effects on pollen and pollinator visitation in a buzz‐pollinated glycophyte, Solanum carolinense

American Journal of Botany, EarlyView.
Abstract Premise Human activity has significantly altered the salt cycle, affecting an estimated 2.5 billion acres of soil worldwide. Elevated soil salinity is a well‐known plant stressor, but it may also affect interactions between plants and insects, which are often sodium limited.
