Towards Zero Hunger – Hands-on: Monitoring Land Degradation

with Sentinel 3 Data
using the Land Cover Data and
Band Maths Tool
in SNAP & QGIS

This hands-on tutorial is part of a series of online learning materials.

Towards Zero Hunger will give you insights into the potential of remote sensing technologies to support the United Nations’ Sustainable Development Goal 2: Zero Hunger.

This tutorial teaches how to use SNAP software to detect active fires with Sentinel-3 SLSTR data, using the June 2017 wildfires in Portugal as a case study. It provides step-by-step guidance on pre-processing data, including radiance-to-reflectance conversion, resampling, and subsetting. The tutorial demonstrates algorithms for daytime and nighttime fire detection and emphasizes creating cloud masks to improve analysis accuracy. The goal is to enhance the ability to monitor and analyze active fire events, contributing to better wildfire management and environmental assessment.

SDG 2: Zero Hunger Relevance

Wildfires can devastate agricultural lands, degrade soil quality, and disrupt food production, all of which can negatively affect food security. Effective monitoring and management of active fires are essential for protecting agricultural resources, maintaining soil fertility, and supporting sustainable food systems. Early detection of wildfires enables timely responses, minimizing damage to croplands and grazing areas, which are critical for food production. Additionally, managing fire-affected areas helps restore degraded lands, improving agricultural resilience and supporting food security. By integrating advanced fire detection tools like Sentinel-3 SLSTR, efforts to mitigate wildfire impacts, stabilize agricultural outputs, and enhance food security can be strengthened, contributing to global efforts to achieve Zero Hunger.
