Published: July 25, 2023

Land use/land cover (LULC) change is a prominent problem and source of greenhouse gas (GHG) emissions in tropical forests. However, little to no evidence available on the contribution biosphere reserves reversing LULC trajectories reducing GHG emissions, particularly Afromontane The objective this study was quantify change-induced from 1999 2020 forests that were designated Sheka Forest Biosphere Reserve (SFBR) by MAB program UNESCO 2012. IPCC Tier 1 approach used estimate emissions. results showed aggregated 0.4 tonnes CO2e ha−1 yr−1 1999, while they climbed 1.46 2010 5.2 2020. Deforestation forest degradation, expansion cropland, development tea plantations, settlement expansion, degradation wetlands contributed increased 40.4%, 32.2%, 17.6%, 8.3%, 1.5% 60%, 20%, 5.2%, 14.4%, 0.33% 2020, respectively. As result, compared 9.03 overall mitigation potential SFBR decreased 12.6% 40.2% findings suggest SFBR's capacity reduce neither enhanced nor maintained its designation as reserve. Therefore, regularly monitoring effectiveness interventions reconciling conflicting land use priorities would be essential for maintaining Promoting tree planting, afforestation, reforestation, restoring degraded landscapes play vital role minimize enhance ecosystem.

Using vegetation and chlorophyll indices to model above ground biomass over time in an urban arboretum in subtropical queensland

Remote Sensing Applications Society and Environment, Journal Year: 2024, Volume and Issue: 34, P. 101202 - 101202

Published: April 1, 2024

As urban forests grow, they can provide a range of ecosystem services, including by sequestering carbon in the form above ground biomass (AGB). Data from satellites is starting to be used estimate ecological functions AGB. In this study, we compare individually and combination five vegetation index three chlorophyll specific indices based on Sentinel-2 satellite images spring (September November) newly planted multi-species arboretum over eight years subtropical Queensland, Australia. There was variation within arboretum, but some clear patterns among time reflecting growth forest. Using published simple regression model AGB as function Leaf Area Index (LAI), found Modified Soil Adjusted Vegetation (MSAVI) Chlorophyll Absorption Ratio (MCARI) best predicted (r-square=0.52 r-square=0.84, respectively), gave (r-square=0.85). The performance these chlorophyll-specific (MSAVI MCARI) reinforces their benefits traditional characterizing could complement field-based sampling when modelling sequestration potentials mixed species forests.

Published: Oct. 10, 2023

Global climate change is one of the major challenges facing world, and spatial optimization land use patterns has been regarded as critical in realizing carbon mitigation. In this study, linear programming model Markov Chain are integrated different scenarios to optimize structure for low-carbon development. The pattern then simulated through adjusted convolutional neural network cellular automata model, taking Guangzhou City case study area. results reveal that construction with high economic efficiency will increase its area, reaming types experience slight changes, 2035 natural development scenario priority scenario. Ecological such forest land, grassland, water partly occupied by urban–rural fringe areas. total emissions decrease 2.32% 1.57% these two scenarios. low-carbon-oriented scenario, expansion restricted, grassland undergo great expansion. emission decreases 18.95%—a figure much larger than Our paper embeds needs constraints planning into pattern, which provides valuable references city future.

Abstract. Marimpan LS, Purwanto RH, Wardhana W, Sumardi. 2022. Carbon storage potential of Eucalyptus urophylla at several density levels and forest management types in dry land ecosystems. Biodiversitas 23: 2830-2837. Tropical forests can store high amounts carbon because they have suitable environmental factors. Furthermore, are different from others that grow areas, which tend to experience limited rainfall. Ampupu (Eucalyptus urophylla) is an endemic tree East Nusa Tenggara, continuously damaged. This caused by various anthropogenic activities, increase along with the population around forest. Therefore, this study aims estimate content stored natural areas E. use types. Field inventory was carried out location using stratified sampling method, after were divided into three groups, viz. high, medium, low. Sampling then 3 land-use including production, protection, conservation forests. a total 90 plots used, where each type consists 30 size 25 m × 40 m. The results showed low, medium high-density 108.20, 185.24, 291.33 MgCha-1, respectively.

The chapter delves into the complex dynamics of post-industrial landscapes, exploring dual impacts industrialization on economic growth and environmental degradation. It emphasizes existence abandoned industrial structures as significant remnants heritage underscores urgent need for biodiversity restoration lands through contemporary ecology. Despite constituting a mere one percent global land surface, these areas hold potential environmental, social, benefits redevelopment green spaces. highlights challenges faced in initiatives, including contamination limited finances, but argues their crucial role sustainable use mitigating impacts. Various landscape types, drivers post-industrialization, factors influencing are explored. importance ecosystem services provision is underlined, emphasizing correlation between increased enhanced services. Post-industrial offer range services, contributes to improved well-being. Strategies restoration, phytoremediation habitat creation, discussed, along with such fragmentation invasive species proliferation. Successful case studies from around world provide insights diverse approaches outcomes, highlighting evidence-based practices.
