EMSN051 : Agriculture Products

The Context

Following the multiple storms and hurricanes the state of agricultural surfaces is unknown to the Haitian authorities. What was the percentage of plots affected ? Have some activities been more affected than others ? Following the hurricane, have the lands seen a change in their use? Current information does not make it possible to take stock of Hurricane Matthieu.

Products

The purpose of these products is to obtain a detailed map of agricultural activities in the selected areas of interest, a product of crop classification and the status of agricultural land with its evolution, where current land use data are compared to baseline data, collected before the event. This product must lead to a change in land use, conversion, or abandonment of land.

During the Copernicus EMS R&R 051 activation different maps were produced:

  • 3 detailed map products of pre-Matthew agricultural activities (Jérémie, Port-Salut and Les Cayes)
  • 3 detailed map product of post-Matthew agricultural activities (recent status for Jérémie, Port-Salut and Les Cayes)
  • 3 detailed map product of agricultural land status and its change (Jérémie, Port-Salut and Les Cayes)

Transmission of products

The maps produced and the corresponding files were sent to CNIGS, CIAT and ONEV for printing and local distribution.

A training session was held in December 2018 to train the experts in the production and operation of the product and the corresponding database. The methodology was presented, then a practical work was done. The CNIGS has also benefited from databases and cartographic products.

Feedback from experience

For this product, it was particularly easy to extract the woody vegetation, and to reclassify it according to a surface / density criterion.

Nevertheless, in order to highlight the permanent low vegetation and cultivated areas, it is necessary to treat a large volume of images (at different resolutions) on each study area in order to better cover the annual cycle of vegetation.

It is still impossible to differentiate the type of crops, because there is no field data, nor images that can cover crop seasons, and the agricultural calendar in Haiti is far too complex (subsistence agriculture, and not intensive).

Moreover, there are many study areas to be treated, and the size of the plain of Les Cayes is very important. There are also many occurrences of change, and it is necessary to aggregate and highlight only the most relevant ones.
