Integrating Remote Sensing, Proximal Sensing, and Probabilistic Modeling to Support Agricultural Project Planning and Decision-Making for Waterlogged Fields

چکیده

Waterlogging in agriculture poses severe threats to soil properties, crop yields, and farm profitability. Remote sensing data coupled with drainage systems offer solutions monitor manage waterlogging agricultural systems. However, implementing projects such as is associated high uncertainty risk, substantial negative impacts on profitability if not well planned. Cost–benefit analyses can help allocate resources more effectively; however, scarcity, uncertainty, risks the sector make it difficult use traditional approaches. Here, we combined a wide range of field remote data, unsupervised machine learning, Bayesian probabilistic models to: (1) identify potential sites susceptible at scale, (2) test whether installation would yield positive benefit for farmer. Using K-means clustering algorithm water vegetation indices derived from Sentinel-2 multispectral imagery, were able detect investigated (elbow point = 2, silhouette coefficient 0.46). combination statistical model A/B test, show that system increase by 1.7 times per year compared existing management. The posterior effect size yield, cropping area, time (year) was 0.5, 1.5, 1.9, respectively. Altogether, our results emphasize importance data-driven decision-making project planning resource management wake smart food security adaptation climate change.

Decision-Support Planning and Tools: Planning to Support Decision-Making

As the Army increases its focus on decisive action, more units are emphasizing decision-support templates and matrices as part of the planning process. Unfortunately, these tools have only minimally impacted tactical decision-making and mission outcomes because leaders are using these tools as another synchronization tool rather than focusing on decision points. When used correctly, decision-su...

Application of a Gis as a Modeling Tool for Remote Sensing Image Analysis of Agricultural Fields

In the context of the analysis of remotely sensed data the question arises of how to analyse large volumes of data. In the specific case of agricultural fields in flat areas these fields can often be modelled in terms of geometric primitives such as triangles and rectangles. In this case the options are classical i.e. bottom-up, starting at the pixel level and resulting in a segmented, labelled...

Mapping Cropland in Smallholder-Dominated Savannas: Integrating Remote Sensing Techniques and Probabilistic Modeling

Traditional smallholder farming systems dominate the savanna range countries of sub-Saharan Africa and provide the foundation for the region’s food security. Despite continued expansion of smallholder farming into the surrounding savanna landscapes, food insecurity in the region persists. Central to the monitoring of food security in these countries, and to understanding the processes behind it...
