To study the impact of pesticide uses in agriculture on human health, data were collected to represent the spatial dynamics of pesticide uses over time: i) a database of agricultural practices regarding the use of pesticides and their evolution over 50 years for the main three gr... |
Dufleit, Victor; Barbarin, Florian; Henaff, Axel; Taizieres, Benjamin; Bonnal, Vincent; Cattan, Philippe; Chery, Jean-Pierre; Tran, Annelise, 2024, "Banana, sugar cane and market gardening plots, Guadeloupe, 1987", https://doi.org/10.18167/DVN1/LYC8N8, CIRAD Dataverse, V1
A map of banana, sugarcane and market gardening plots was produced from scanned paper maps of Guadeloupe in 1987 published by the French Agriculture and Forestry Department. Paper maps have been digitized and georeferenced to be integrated into a Geographic Information System env... |

A map of banana and sugarcane plots was produced from scanned paper maps of Guadeloupe in 1969 published by the French National Geographic Institute. Paper maps have been digitized and georeferenced to be integrated into a Geographic Information System environment. Then, vectoriz... |
Andriamampianina, Zaka; Rajaonson Nosy, Vokatsoa Lahatra; Andriamampionona, Lôla; Dupuy, Stéphane; Muller, Bertrand, 2023, "Itasy, Vakinankaratra - Madagascar - 2023 - Land cover reference spatial database", https://doi.org/10.18167/DVN1/5GHE96, CIRAD Dataverse, V1
This reference database in vector format (ESRI shape format) is organised according to a multi-level nomenclature. It is used to train an image classification algorithm with a view to producing land use maps for the Itashy and Vakinankaratra regions as part of the DINAAMICC proje... |
Dupuy, Stéphane; Lebourgeois, Valentine; Gaetano, Raffaele, 2023, "Itasy, Vakinankaratra - Madagascar - 2022-2023, Land cover map", https://doi.org/10.18167/DVN1/TKTPCH, CIRAD Dataverse, V1
The land use maps published here were produced for the communes studied by the DINAAMICC project for the period 2022-2023 (based on GPS collected in the field in March 2023). They partially cover the Itasy and Vakinankaratra regions. The reference database used to produce this ma... |
