Socioenvironmental implications of Jatropha curcas cultivation for biodiesel supply in postmining communities

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The long‐term viability of Jatropha curcas as a biodiesel feedstock has been widely debated. Many early initiatives failed to deliver consistent economic returns despite promising environmental attributes. This study re‐evaluated J. curcas‐based systems within an integrated environmental–economic framework, focusing on their potential role in ...

Farmers’ response to COVID-19 disruptions: The case of cropland allocation decision

open access: yesSustainable Futures, 2022
This study provides new evidence on the determining factors of cropland allocation decisions within the context of the COVID-19 pandemic by using the seemingly unrelated regression (SUR) model on 309 farm households.

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

The Yield and Pest Trade-Off: An Analysis of Insecticide Spray Frequency on the Performance of a Genetically Modified Cowpea in Ghana

open access: yesAgronomy
A field trial was conducted at two locations in northern Ghana over two successive years to determine the optimal insecticide application timings for mitigating non-lepidopteran pest infestations in a cowpea (Vigna unguiculata (L.) Walp.) variety ...

Spatial metrics in fire ecology: seeking consistency amidst complexity

open access: yesBiological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Classifying avian drinking behaviour: ecological insights and implications in a changing world

open access: yesBiological Reviews, EarlyView.
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

Growth and Fruit Yield of Okro as Influenced by Genotypes and Mulch in the Guinea Savannah Conditions of Ghana

open access: yesInternational Journal of Agronomy, 2017
The experiment was carried out to assess the suitability of different mulch materials in enhancing the growth and fruit yield of okro. Ten okro genotypes were evaluated in a split plot design with 3 replications. Three treatments of mulch (black plastic,
