Carbon, Nitrogen, and Corresponding Stable Isotope Signatures Reveal Channel Banks as Major Sediment Sources in a Tropical Agricultural Watershed

Land Degradation &Development, EarlyView.
ABSTRACT Uncertainties about the applicability of δ13C and δ15N as tracers of sediment sources in tropical river basins highlight the need for more in‐depth investigations of these isotopes. This study therefore assessed the effectiveness of δ13C and δ15N signatures in discriminating sediment sources in an agricultural catchment in Northeast Brazil ...

THE DYNAMICS OF LAND-COVER CHANGE IN WESTERN HONDURAS: SPATIAL AUTOCORRELATION AND TEMPORAL VARIATION [PDF]

This paper presents an econometric analysis of land-cover change in western Honduras. Ground-truthed satellite image analysis indicates that between 1987 and 1996, net reforestation occurred in the 1,015.12 km2 study region.

Species identity and spatial scale drive context‑dependent tree diversity effects in a Finnish forest experiment

Oikos, EarlyView.
Tree species diversity is known to affect tree growth and leaf traits, which in turn can influence various ecosystem processes. However, the reported direction of these tree diversity effects is inconsistent, indicating that their outcomes depend strongly on ecological context.

Site Suitability Assessment of Native Tree Species in Angat Watershed using GIS-based Multi-Criteria Decision-Making [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Forests are one of the Philippines’ most valuable resources but due to reasons such as deforestation, its forest cover drastically decreased, requiring reforestation efforts.

Understanding contingency in wolf‐mediated livestock predation across a mosaic of land uses: An agent‐based modelling approach

People and Nature, EarlyView.
Abstract The return of grey wolves to multi‐use landscapes in North America and Europe raises concerns over accompanying risks of livestock predation. While local‐level risk factors have received attention, it is difficult to explore the role that landscape‐scale variables, such as landscape connectivity, play in driving livestock losses.

The Composition of Nitrogen-Fixing Microorganisms Correlates With Soil Nitrogen Content During Reforestation: A Comparison Between Legume and Non-legume Plantations

Frontiers in Microbiology, 2019
Numerous reforestation projects have been conducted to improve soil fertility in degraded forests, often causing alterations to the soil microbial communities.

Digital nature in the AI era: How human and AI‐generated representations shape future visions of rewilding

People and Nature, EarlyView.
Abstract Rewilding has gained significant influence in nature conservation, offering hopeful narratives that address the interconnected challenges of climate change and biodiversity loss while enabling people to reconnect with ‘wildness’ in the Anthropocene.

Reforestation in a high‐CO2 world—Higher mitigation potential than expected, lower adaptation potential than hoped for

Geophysical Research Letters, 2016
We assess the potential and possible consequences for the global climate of a strong reforestation scenario for this century. We perform model experiments using the Max Planck Institute Earth System Model (MPI‐ESM), forced by fossil‐fuel CO2 emissions ...

Reforestation challenges 2018

REFORESTA, 2018
The conference on "Reforestation Challenges" took place on 20-22 June 2018 in Belgrade, Serbia, at Faculty of Forestry of the University of Belgrade. This was the fourth meeting on reforestation challenges, after three successful meetings in three previous years (2015 – Belgrade, Serbia; 2016 – Krakow, Poland; 2017 – Session at the IUFRO Congress in ...
