Land cover changes and inter-annual vegetation performance

Challenge Description

WFP’s interventions are not only related to emergency or crisis responses. WFP programs include interventions that aim to enhance the resilience of communities and the increase in community assets. These are known as FFA (Food for Assets) and may include things like the building of dams, restoration of irrigation capacity, afforestation, etc. WFP has an interest in monitoring not only if the asset was built, but also the degree to which the planned outcomes have been realized (e.g. X ha converted to irrigated vegetable gardens).

On the other hand, the emergence of large scale conflict in areas of WFP interest highlighted the need to provide a quantification of the amount of cropland abandoned due to conflict. Analysis of optical imagery (Sentinel-2 and Landsat archives) can provide a tool for automated land cover change detection, helping WFP to quantify:

1. The impact of WFP restoration activities on their local environment (irrigation canals, land rehabilitation, dams, roads, etc.),
2. The impact of conflicts on agricultural resources in hard-to-access areas (cropland abandonment, land degradation).

Results

The results below are divided into Software Repositories, Online Services and Data Products Repositories.
In case you would like to get in touch with us about specific results, please use the indicated reference codes (e.g. WFP-01-01-01).

Software Repositories

There are two categories of software repositories generated for the Challenge:

• GitLab repositories are hosting the reference software code, for use by the team members of a challenge only (restricted access)
• GitHub repositories are hosting the public software code (mirrors), for engagement and collaborative work with the broad community of software developers (public access)

Follow the links below to proceed to one or the other, and find an "Ellip Workflows (ewf)" software application implementing a data processing function.
You can adapt this software to your own context, commit a contribution to the related repository, or engage with the BETTER consortium to run it for a specific purpose (new area of interest, ...) by requesting Cloud resources to support (at) terradue.com

Data Processing as-a-Service

There are two categories of "Data Processing as-a-Service" application packages created for the Data Challenge:

• Data Processing Pipelines are controlling full EO data production campaigns, for use by approved members of a challenge only (authorized access),
• On-demand Processing Services are controlling individual EO data processing jobs, also for use by the approved members of a challenge only (authorized access).

Follow the links below to proceed to one or the other, via a dedicated Geobrowser application providing web access to one or the other of the Data Processing services.
You can engage with the BETTER consortium to request authorized access via support (at) terradue.com

Data Product Repositories

There is a dedicated client App publicly available for the visualization of the data products resulting from EO data processing challenges.

The results can consist of:

• Validation data: small amount of data products generated for approval by the Challenge promoter
• Production campaign data: full-time series/collection of data products answering the Challenge promoter question about Earth Observation data being used to help solve global societal challenges
