Comparative field‐scale assessment of TLUD and Kon‐Tiki biochar systems: agronomic performance and net CO2e‐based techno‐economics

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Tropical dry forest recovery : processes and causes of change

, 2009
Seasonally dry areas are one of the preferred zones for human inhabitance in the tropics. Large forest areas are converted to other land uses and many are covered by secondary forests that grow naturally after cessation of disturbance.

Restoring Trust: Rebuilding the Forest Carbon Credit System Through Scientific Rigor

Biological Diversity, EarlyView.
ABSTRACT As pivotal nature‐based climate solutions (NbCS), forests are increasingly recognized for their climate mitigation potential. However, this potential is undermined by fundamental flaws in current carbon credit systems. Our analysis identifies four interconnected systemic challenges: (1) subjective additionality assessments arising from ...

Density Estimates of Endangered Endemic Rodents Suggest Broader Impacts of Invasive Burmese Pythons Following a Category 4 Hurricane in the Florida Keys

Biological Diversity, EarlyView.
Density estimates of two endangered rodent subspecies, endemic to Key Largo, Florida, USA. These findings illustrate the contrasting dynamics of two native species associated with the prevalence of invasive Burmese pythons and global change. The woodrats' decline emphasizes its potential risk of extinction as global change continues to impact island ...
