Article
Full-text available
Human modification of hydrological connectivity of landscapes has had significant consequences on ecosystem functioning. Artificial drainage practices have fundamentally altered northern landscapes, yet these man made channels are rarely considered in ecosystem management. To better understand the effects of drainage ditches, we conducted a landsca...
Article
Monitoring the changes in soil organic carbon (SOC) pools is critical for sustainable soil and agricultural management. This case study models total and active organic carbon dynamics (2015/16 to 2019/20) using digital soil mapping (DSM) techniques. Model predictors include topographic variables generated from LiDAR data; soil and vegetation indice...
Preprint
A critical tool to succeed in sustainable spatial planning is accurate and detailed maps. To meet the sustainable development goals and enable sustainable management and protection of peatlands, there is a strong need for improving the mapping of peatlands. Here we present a novel approach to identify peat soils based on a high-resolution digital s...
Article
Full-text available
Spatially extensive high-resolution soil moisture mapping is valuable in practical forestry and land management, but challenging. Here we present a novel technique involving use of LIDAR-derived terrain indices and machine learning (ML) algorithms capable of accurately modeling soil moisture at 2 m spatial resolution across the entire Swedish fores...
Article
Increasing soil organic carbon (SOC) can improve the capacity of agricultural systems to both adapt to and mitigate climate change. Despite its importance, the current understanding of the magnitude or even the direction of SOC change in agricultural landscapes is limited. While changes in land use/land cover (LULC) and climate are among the main d...
Thesis
Globally, the agriculture sector is constantly being challenged by multiple climate change-induced stresses while agricultural activities are responsible for a large portion of global greenhouse gas emissions. At the same time, agroecosystems have a sizable potential to mitigate climate change through the sequestration of atmospheric carbon-dioxide...
Article
Climate change is presenting sizeable challenges for agricultural production around the world. In some regions, shifting precipitation patterns in the spring and fall are negatively impacting farm operation by reducing the number of “workable days” or the days fields can be worked with heavy equipment without damaging soil structure. This can be pa...
Article
Full-text available
We combined multi-layer perceptron (MLP) neural network and Markov Chain (MC) modeling with object-based image analysis (OBIA) to map and predict land use and land cover (LULC) changes in Stoney Creek Watershed (SCW), British Columbia, Canada. Unsupervised classification was performed using Landsat Thematic Mapper (TM) and Operational Land Imager (...
Article
The performance of digital soil mapping (DSM) model is highly reliant on the intensity and spatial distribution of the input soil data points. Increasing the number of soil data points (i.e. samples) improves the accuracy of the prediction, but it also raises the sampling effort, including the time, money and labor required for field and laboratory...
Article
Full-text available
Dhaka city the capital of Bangladesh experienced unprecedented urban growth since the country’s independence in 1971. A significant portion of the urbanization took place in the encroached surface water body and floodplain (SWB and FP) areas. We thus aimed to capture the depletion of SWB and FP in Dhaka city from 1967 to 2008 using geospatial analy...
Article
Land use – land cover (LULC) change and the associated risk of soil erosion have become a global environmental concern. We herein presented a geospatial analysis to detect LULC changes (1984-2010) in a Canadian watershed by using object based classification of Landsat satellite images. We found that the watershed experienced a substantial increase...
Conference Paper
Managing agricultural soil is a significant challenge given the changing climate and the intensification of farming practices. For example, shifting precipitation patterns, caused by climate change can impede a farmer’s capacity to manage their fields with heavy equipment without causing long-term damage to the soil. This is highly problematic as h...
Article
Full-text available
Object oriented image classification (OOIC) and neural network aided Markov Chain (MC) modeling tools were used to map and predict land use and land cover (LULC) changes. A case study in the Kiskatinaw River Watershed (KRW) of Canada was presented. With an overall classification accuracy of 90.45%, the multi-temporal Landsat satellite images of KRW...
Article
Groundwater-surface water (GW-SW) interaction plays a vital role in the functioning of riparian ecosystem, as well as sustainable water resources management. In this study, temporal dynamics of GW-SW interaction were investigated under climate change. A case study was chosen for a study area along the Kiskatinaw River in Mainstem sub-watershed of t...
Conference Paper
Background/Question/Methods: Advancement of new technologies including high precision GPS, remote sensing and GIS has greatly improved our ability of the spatial prediction of soil properties using digital soil mapping (DSM). DSM is considered highly valuable for planning and implementing agro-ecological projects, or evaluating the availability o...
Conference Paper
Remote sensing (RS) servesasa non-destructive and cost-effective alternativefor biomass estimation in agricultural lands. Recently,data captured by unmanned aerial vehicles(UAV)hasgained popularity for biomass mapping due to its high resolution, cost effectiveness,and flexibility of image acquisition. Typically,methodsfor biomass mapping using RS d...
Conference Paper
Background/Question/Methods: Downscaled climate models predict warmer temperatures and shifting precipitation patterns for the delta of British Columbia’s Fraser River, one of the most productive agricultural regions in Canada. Shifting precipitation has already resulted in wetter soil conditions during spring and fall when mechanized operations a...
Conference Paper
Delta, one of the most productive agricultural regions in British Columbia, faces numerous challengesfor maintaining soil quality.Current intensive production practices coupled with shifting precipitation patterns are contributing to soil compaction, increased soil salinity and loss of soil organic carbon(SOC). Often these changes in soil quality a...
Conference Paper
Kiskatinaw River Watershed (KRW) in north-eastern British Columbia of Canada serves as a crucial water resource for the Peace River Regional District. Over decades, the dominant land use activity in this densely forested watershed has been forestry and agriculture, but rapid and intensive natural gas development in recent years has greatly affected...
Article
Full-text available
The effects of land use change on surface water quality in an intensively used watershed in northern British Columbia were investigated. The water of the Kiskatinaw River watershed (KRW) was analyzed for its total organic carbon (TOC) concentration in 2004-2005 and 2010-2011, and the variation of water quality within sampling sites over time was ex...
Thesis
This thesis study was conducted to capture the land use and land cover (LULC) change dynamics in Kiskatinaw River Watershed, BC, Canada. A combination of remote sensing, GIS and modeling approach was utilized for this purpose. Landsat TM and ETM+ satellite images of the years 1984, 1999 and 2010 were analyzed using object oriented image classificat...
