Radical Listening as a Governance Innovation: Integrating Planetary Health and Community‐Led Forest Conservation in Indonesia

Environmental Policy and Governance, Volume 36, Issue 4, Page 1128-1146, August 2026.
ABSTRACT While REDD+ prioritizes carbon sequestration, its narrow focus often overlooks forest‐health linkages critical to community well‐being. This paper examines the holistic model of Health in Harmony (HIH) and Alam Sehat Lestari (ASRI), which integrates forest conservation with healthcare through radical listening—a decolonial community engagement

Swish‐Gumbel: A New Activation Function for Image Classification

Concurrency and Computation: Practice and Experience, Volume 38, Issue 14, July 2026.
ABSTRACT In this study, we present Swish‐Gumbel, a new family of activation functions generated by combining the Swish and Gumbel functions through both multiplication and linear composition. We evaluate their performance on several image classification benchmarks, including MNIST, CIFAR‐10, Imagenette, and Beans, using different deep learning ...

Enforcing environmental law in the Amazon

People and Nature, Volume 8, Issue 7, Page 2281-2294, July 2026.
Abstract This article identifies the underlying obstacles to enforcement of laws against environmental crimes such as illegal logging, mining and ranching. With four departments (provinces) from Colombia as case studies, it assesses enforcement of the country's main environmental law, Law 2111, which is one of Latin America's strongest. The article has

Activity recognition in motor-manual cross-cutting operations by machine learning on multimodal data

Forest Science and Technology
In forest operations, established time-study methods, such as the use of a stopwatch and video recording, have dominated for several years. Advancements in machine learning and innovative data loggers present opportunities to reconsider and enhance these

Regulating bark beetles with mechanical bark treatments: Trade‐offs among pest control, operational efficiency and biodiversity

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Three times harvester processing and motor‐manual bark gouging effectively reduce bark beetles, enabling two options: permanent on‐site retention for biodiversity conservation, or up to 2 years of intermediate on‐site storage with no treatment effect on blue‐stain fungi colonization or energy content, thereby buffering operational bottlenecks during ...

Investigation on the ergonomic aspects of the noise caused by chainsaw in bucking operation (Case study: Kheyrud forest research station) [PDF]

مجله جنگل ایران, 2013
Forestworkers are exposed to many noise sources such as chainsaw. Chainsaw these days is the only cutting trees instrument used in Caspian forests. The purpose of this study is to measure the noise of pressure levels of chainsaw and to determine the ...

Growth, mortality and regeneration responses to ecological forestry treatments are shaped by local factors, species, and initial treatment impact

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
In mixed stands, coniferous species showed growth benefits when coexisting with broadleaf species, possibly due to reduced intraspecific competition or improved access to resources mediated by broadleaf neighbours. This growth advantage was not observed for broadleaf species, indicating asymmetric benefits in mixed stands.

Therapeutic Bark Gouging as an Effective Complement for the Management of Ips typographus and Pityogenes chalcographus While Preserving Habitat for Secondary Scolytine (Coleoptera: Curculionidae) Species

Journal of Applied Entomology, Volume 150, Issue 6, Page 780-790, July 2026.
ABSTRACT Norway spruce will likely remain an important tree species in Europe over the next few decades despite efforts to transform forests and reduce its distribution range more to its natural range. Consequently, Ips typographus will remain one of the most relevant forest pests the management of which will become increasingly challenging due to ...
