CHOVE-CHUVA

The CHOVE-CHUVA project aims to develop a tool for monitoring territorial dynamics in Mato Grosso, in the Brazilian Amazon. This service will provide simple indicators on the evolution of climate and land use variables. Citizen data on the perception of climate change and on the location of rational land use practices will also be collected.

OVERVIEW

The Brazilian Amazon, and in particular the State of Mato Grosso, has long been the scene of intense socio-environmental transformations, at the heart of the challenges of global change. These transformations are mainly explained by a very dynamic agricultural sector that, beyond its expansion strategy, is evolving to intensify and diversify its practices. This evolution is taking place in Brazil in the context of a sectoral plan for climate change mitigation and adaptation (Plan ABC; Agricultura de Baixa Emissão de Carbono) whose objective is to encourage the adoption of sustainable management practices: restoration of degraded pastures and reforestation of riparian areas, promotion of reasoned agricultural practices such as crop-livestock integration or direct seeding...

However, tools that allow citizens and community associations to have synthetic access to the evolution of conditions in their territory are sorely lacking. However, there is a great diversity of spatial information on the subject that should be disseminated to as many people as possible in order to support and facilitate the adaptation processes of communities to these changes.

The objective of the CHOVE-CHUVA project is to develop a tool for monitoring territorial dynamics in Mato Grosso. This demonstrator will be based on two major components: 1) the dissemination of spatial information on the evolution of climatic variables and the dynamics of land use (forests, agriculture, water resources) and use (agricultural practices), and 2) the collection of citizen data on the perception of climate change by Amazonian communities and on the location of certain types of land use advocated under the ABC plan such as reforestation or plots cultivated in integrated systems.

RESULTS - FINAL PRODUCTS

The proposed tool has two purposes:

  1. Dissemination of spatial information

The primary objective of the tool is to make available to the greatest number of spatio-temporal indicators testifying to the territorial dynamics observed in Mato Grosso in connection with adaptation and mitigation strategies implemented by societies. Thus, we propose to mobilize information allowing, for a zone predefined by a user, to produce a "dashboard" of the territorial situation from synthetic indicators on 4 major themes:

  • Climate: precipitation evolution (quantities and seasonality)
  • Forests: changes in forest cover (deforestation and degradation)
  • Water: evolution of pressures on water resources (creation of water reservoirs and degradation of riverbanks)
  • Agriculture: evolution of agricultural surfaces (surface areas and practices)
  1. Citizen data collection

The second objective of the tool is to take advantage of user visits to collect citizen data that can be used for future research. Thus, the data collection consists of:

  • an online survey on the perception of climate change by local actors.
  • the possibility given to users to locate on a satellite map types of land use advocated in the framework of the ABC plan (e.g. plots in integrated crop-livestock systems, reforestation areas).
