An integrated method is required for comprehensive assessment of the environmental impacts and economic benefits rice production systems. Therefore, objective this study was to apply different footprinting approaches (carbon footprint (CF), nitrogen (NF), water (WF)) determine return on organic farming (OF) conventional (CVF) at farm scale. Over 4-year period (2018–2021), results showed lower net greenhouse gas (GHG) emissions in OF (3289.1 kg CO2eq ha−1 year−1) than CVF (4921.7 year−1),...

Soil microorganisms play an important role in determining nutrient cycling. The integration of fish into rice fields can influence the diversity and structural composition soil microbial communities. However, regarding rice-fish co-culture (RF) farming system Thailand, study microbes is still limited. Here, we aim to compare diversity, community composition, functional structure bacterial communities between RF monoculture (MC) systems identify environmental factors shaping composition....

Rice straw and stubble burning is widely practiced to clear fields for new crops. However, questions remain about the effects of fire on soil bacterial communities properties in paddy fields. Here, five adjacent farmed were investigated central Thailand assess changes after burning. Samples prior burning, immediately 1 year obtained from depths 0 5 cm. The results showed that pH, electrical conductivity, NH4-N, total nitrogen, nutrients (available P, K, Ca, Mg) significantly increased due an...

Increasing production costs for rice monoculture and concerns about farming households’ food security have motivated farmers to adopt integrated rice–fish farming. To date, there has been little research that comparatively assesses the ecosystem services (ESVs) of both co-culture system in Thailand. Therefore, this study aims estimate ESV values these systems based on Millennium Ecosystem Assessment. A total 19 farms were investigated, covering three regions Thailand (northern, northeastern,...

Numerous studies have been undertaken to determine the optimal land use/cover classification algorithm. However, there not many that compared and evaluated performance of maximum likelihood (ML), random forest (RF), support vector machine (SVM), regression trees (CART) using ASTER imagery, especially in a mining district. Therefore, this study aims investigate (LULC) change over three decades (1990–2020), comparing ML, RF, SVM, CART learning algorithms. The Landsat data were retrieved Google...

The hill tribes in Thailand traditionally depend on rotational shifting cultivation (RSC). However, insufficient understanding remains post-fire soil properties and erodibility ( k -values) with fallow years. To address this gap, the levels of organic carbon (SOC), total nitrogen (STN), nutrients, after fire RSC were investigated. Topsoil (0–10 cm) samples from sites 4 (RSC-4Y), 5 (RSC-5Y), 7 (RSC-7Y) years Chiang Mai Province, northern Thailand, taken at four time points: before burning,...

Soil microbial communities are ubiquitous and essential for the functioning of soil system. The use fire is a common practice in rotational shifting cultivation (RSC) to clear land after cutting vegetation cultivation. However, three main questions remain unanswered: (1) What more sensitive between bacteria fungi RSC fields? (2) kinds bacterial fungal taxa resistant (3) Does affect complexity networks To address these questions, surface samples (0–2 cm depth) were collected from sites with...

Fire is a common practice in rotational shifting cultivation (RSC), but little known about the dynamics of bacterial populations and impact fire disturbance northern Thailand. To fill research gap, this study aims to investigate soil communities examine how soil’s physicochemical properties influence RSC fields over period one year following fire. Surface samples (0–2 cm depth) were collected from sites with 6 (RSC-6Y) 12 (RSC-12Y) years fallow Chiang Mai Province, Thailand at six different...

Since fire is still necessary for rotational shifting cultivation (RSC), the vertical distribution and slope effect on soil properties surface loss after a remain unclear. To address these research gaps, study aims to achieve following objectives: 1) investigating post-fire in RSC, 2) assessing RSC. Soil samples were collected from two stages of RSC: 6 years (RSC-6Y) 12 (RSC-12Y), located Chiang Mai Province, Northern Thailand. A continuous 15-year left fallow field (CF-15Y) was used as...

Particulate pollution is a continual problem which usually caused by the burning of crop residues in highland agricultural systems. The objectives this study are to investigate crop-residue management and estimate amount pollutant emissions from for each land-use pattern (grain maize, seed maize integrated farming), chemical compositions PM2.5 Mae Chaem basin, Chiang Mai Province, Thailand. purposive sampling method was used sample selection. A door-to-door questionnaire survey obtain...

Understanding the effect of environment, crop types, and land management practices on organic carbon sequestration top soil is crucial for adopting strategies in highland agricultural areas. The objectives this study are: (1) to estimate density (SOCD) different types (2) analyze factors controlling SOCD layers from 0 30 cm depths were collected Mae Chaem basin, Northern Thailand. results showed that highest was found used growing upland rice, which contained an average 58.71 Mg C ha−1.

The first case of COVID-19 infection was confirmed in Thailand on January 13, 2020; since then, work from home and lockdown measures have slowed the spread COVID-19. A more stringent, curfew regulation imposed April 3, 2020. Under these measures, activities businesses, transportation, industrial sectors were reduced or temporally closed. Therefore, this study aims to investigate changes nitrogen dioxide (NO₂) level whole specifically Bangkok metropolitan area. concentrations tropospheric NO2...
