Research Grant Award (№ ДФНП-17-43/26.07.2017), Program for Supporting Young Scientists and PhD Students – 2017 from the Bulgarian Academy of Sciences with the collaboration of Prof. Roumenina E.

Title: Remote Sensing monitoring of rapeseed crops in Northeast Bulgaria.

Period: 08.2017 – 01.2019.

Aim: The study aims to develop a methodology for assessing the condition of winter rapeseed (Brassica napus) crops based on experimental studies, theoretical analyzes and satellite data from Sentinel-2 mission. It is based on the hypothesis that there is a correlation between, satellite vegetation index images and phenological, biometric and physiological indicators of winter rapeseed crops. The existence of such a dependency makes it possible to propose a methodology for assessing the condition of winter rapeseed crops only by land remote sensing methods and to avoid labor-intensive classical methods and therefore to be able to monitor rapeseed crops on a regional and national level. The results of the survey will help improve farming practices in winter rapeseed

RESEARCH PROJECTS

Partner: Corteva-Agriscience

Title: Assess the functionalities of products that help farmers for precision agriculture and their acceptance by farmers in Northeast Bulgaria.

Period: 07.2019 – 08.2019

Aim: Over 20 flights were performed with the drone DJI Phantom 3 Advanced, equipped with RGB and NIR digital cameras, owned by Pioneer ™ Bulgaria over corn and sunflower fields. Determination of the capabilities of dronedeploy.com. Presentation of the results to farmers from Northeast Bulgaria and evaluation of their acceptance of the results.

Partner: Corteva-Agriscience

Title:  Application of Remote Sensing Methods and Geographic Information Systems in the Field of Precise Agriculture

Period: 03.2019 – 07.2019

Aim: The aim of this project is to apply the state-of-the-art technics in remote sensing for retrieval of agronomical and biophysical parameters such as plant density, plant height, biomass, leave chlorophyll content. The focus was given to the application of UAV and multispectral cameras. Further research was to monitor the effect of herbicide, pesticide and drought on different hybrids of sunflower and corn. Several field campaigns were carried. Multiple data and image processing were executed, including classical and patent protected classification techniques and machine learning regression algorithms. Multiple functional maps were produced to be used by the farmers.

Partner: Pioneer™ Bulgaria.

Title: UAV remote sensing monitoring of sunflower, corn and rapeseed 

Period: 03.2017-06.2018

Aim: Training for the use of the drone DJI Phantom 3 Advanced UAV equipped with RGB and NIR digital camera, property of Pioneer™ Bulgaria. Evaluation of Vegetation Indices from the images from the drone and Sentinel-2 for detection of change of vegetation status in sunflower, corn and rapeseed test fields of Pioneer™ Bulgaria in North East Bulgaria

Partner: Black Sea Basin Directorate – Varna

Title: Modelling the ecological niche of macrophythobenthos species along the Bulgarian Black Sea coast

Period: 09.2014-05.2015

Aim: This work is part of the effort to build statistically sound marine monitoring network to support the implementation of Article 11 (coordinated monitoring programmes) of the EU Marine Strategy Framework Directive (MSFD) in Bulgaria for the period 2014-2018. It is known that the existing monitoring is insufficient to meet the requirements of MSFD. A statistically sound sampling strategy is needed to provide adequate data for environmental status assessment. The first step in order to build a marine monitoring network is to develop an ecological niche model (ENM) of each ecosystem of the region. Because of the nature of the available field data, a presence-only ENM was selected and Maxent modelling tool was chosen. A Maxent model of Cystoseira barbata (brown algae) was developed and instructions are provided in order to develop an ENM for the rest of the ecosystems. The environment predictor variables used to develop the Maxent model are existing monitoring information combined with satellite-derived information
