Bangladesh-Barisal, Alamdanga

Overview

Our main focus is on estimating bio-physical parameters such as ground cover (fVeg) and leaf area index (LAI) at different scales. We have collected data on the ground and with a drone.
We also conducted a large campaign in order to determine the area of mung bean in the coastal region of Bangladesh.

Project Objectives

Mapping Agricultural Areas

Operational Implementation Plan

We have conducted a large study under the STARS project for the Barisal site (Fig 1). We collected information on croptypes for 2 years. In the coming season (winter 2016 – 2017), we will start a wheat blast monitoring project, for which we will continue to collect information on crop types.

Estimation of Biophysical Variables

Operational Implementation Plan

We are monitoring subsets of the AOI with an UAV, and some fields are left fallow during the dry winter months.

Biophysical Variables
  • Residue and Tillage mapping

Forecasting Agricultural Variables

Operational Implementation Plan

We will be monitoring soil moisture for irrigation experiments. We will also engage in a yield estimation study on farmers fields in the Dinajpur and Alamdanga regions. For that project, we will collect information on crop types and digitize field boundaries.
