Evidence-based guidelines for greener, healthier, more resilient neighbourhoods: Introducing the 3-30-300 rule

Cecil C. Konijnendijk

Summary: Urban trees and green spaces play important roles in climate moderation and public health. Having trees and vegetation in sight has mental health and performance benefits, and local tree canopy cover is associated with cooling and climate moderation. Proximity to public green spaces stimulates regular use and positively impacts mental, physical, and social health. The '3-30-300 rule' aims to provide equitable access to trees and green spaces by setting thresholds for tree visibility, tree canopy cover, and proximity to public green spaces.

Machine learning in crop yield modelling: A powerful tool, but no surrogate for science

Gunnar Lischeid, Heidi Webber, Michael Sommer, Claas Nendel, Frank Ewert

Summary: This study utilized machine learning methods to investigate the impact of climatic and soil hydrological factors on the yield of four crops, highlighting the uniqueness of key predictors. Random Forest and Support Vector Machine models achieved between 50% and 70% capture of spatial and temporal variance, with different sets of predictors performing similarly. In light of climate change, excess precipitation and heat effects are seen as important factors in crop breeding and modeling.

Mass fire behavior created by extensive tree mortality and high tree density not predicted by operational fire behavior models in the southern Sierra Nevada

Scott L. Stephens, Alexis A. Bernal, Brandon M. Collins, Mark A. Finney, Chris Lautenberger, David Saah

Summary: The study analyzed the behavior and patterns of the 2020 Creek Fire and found that dead biomass and live tree densities were key factors in predicting fire severity. The research highlights the vulnerability of frequent-fire forest conditions to large-scale fires, with past management decisions and drought and bark beetles being critical factors in driving the mass fire.

Global spatiotemporal consistency between meteorological and soil moisture drought indices

M. H. Afshar, B. Bulut, E. Duzenli, M. Amjad, M. T. Yilmaz

Summary: In this study, the consistency between meteorological and soil moisture drought indices was analyzed. The most consistent meteorological drought index with soil moisture drought index was identified as the best representative. The results showed that different meteorological drought indices have varying levels of correlation with soil moisture drought index in different climate and land use conditions. The K-Nearest Neighbor method was found to be the most effective in identifying the most correlated meteorological drought index with soil moisture drought index.

How to promote residents' use of green space: An empirically grounded agent-based modeling approach

Xin Liang, Tingting Lu, Gulinigaer Yishake

Summary: This study proposes an agent-based model to simulate the effectiveness of green space policy measures on residents' decision-making. The results illustrate the unequal effectiveness of different policy scenarios among different social groups and types of green space. Tailored policies are needed to meet residents' heterogeneous needs, and soft policies promoting social interaction and participation play a significant role in the appeal of green space use.

Scaling up nature-based solutions for climate-change adaptation: Potential and benefits in three European cities

Chiara Cortinovis, Peter Olsson, Niklas Boke-Olen, Katarina Hedlund

Summary: This research evaluates the potential and benefits of implementing Nature-based Solutions (NBS) for climate change adaptation in European cities, and how they relate to the urban structure. The study finds that green roofs have the greatest potential to reduce runoff and increase biodiversity, while tree planting contributes the most to heat mitigation and greenness. The results of each scenario can support policy-makers in designing targeted NBS strategies.

Summary: Wood resources have been essential for human welfare throughout history, and growing stock is a key forest attribute monitored by National Forest Inventories. The origins of forest inventories date back to times of wood shortage in Europe, leading to the exploration and planning of wood utilization. Over time, forest surveys have evolved to cover larger areas, with modern NFIs assessing a multitude of variables related to sustainable forest management.

Summary: This study in northeastern Washington State, USA, analyzed 150 fires occurring from 2001 to 2019 in conifer forests, and found that daily fire weather, annual precipitation anomalies, and species' fire resistance traits were important predictors of wildfire burn severity. Previous fires within the past two to three decades reduced the severity of subsequent burns, while prescribed burning was the most effective treatment at lowering subsequent burn severity. Overall, postfire management actions had a weak influence on the severity of subsequent fires, highlighting the importance of stabilizing feedbacks in active fire regimes.

Impacts of Climate Change on Blue Carbon Stocks and Fluxes in Mangrove Forests

Daniel Michael Alongi

Summary: Mangroves have a disproportionate amount of blue carbon stored in their deep soil, accounting for 74% of the total. The global carbon stock estimate of mangroves is equivalent to 15-24% of that in the tropical coastal ocean. They play an important role in carbon sequestration, with carbon burial in their soils averaging 184g/m2/year. Extreme weather events, increasing temperatures, and changes in rainfall can negatively impact carbon stocks and cycling. Forest responses to sea-level rise and rising CO2 are complex and species-specific.

Summary: This paper assesses the potential benefits of gardening on the mental well-being of Singapore residents during the Covid-19 pandemic. The results show that engaging in gardening activities can significantly improve mental resilience. Individuals who gardened regularly had higher mental resilience scores compared to an online community. The efficacy of the mediating effects may peak at a weekly gardening time of one to four hours. Home gardening can serve as an effective way for people living in densely populated cities to interact with nature and build mental resilience.

Design of wood-derived anisotropic structural carbon electrode for high-performance supercapacitor

Feng Wang, Lian Chen, Shuijian He, Qian Zhang, Kunming Liu, Xiaoshuai Han, Gaigai Duan, Shaohua Jiang

Summary: This study explores the development of thick carbon electrodes derived from basswood and their application in high energy density supercapacitors. The anisotropic structural carbon electrodes derived from wood exhibit different transfer kinetics of the electrolyte, which significantly impacts the electrochemical performance, especially at high current density. The results show that the cross-sectional wood-derived carbon with high specific surface area contributes to excellent electrochemical performance, attributed to its hierarchical porous structure that allows easy access for the electrolytes even at high current density. This work provides insights into the dynamic behaviors of electrolyte in different wood sections and can be extended to other wood species and wood-like structures for energy storage applications.
