Terra-i was invited to participate in the 12th Regional Workshop on Forest Monitoring GEO GFOI held at Instituto Nacional de Pesquisas Espaciais (INPE) in São José dos Campos, SP, Brazil (January 19th - 23th, 2015).

The goal of the 12th Regional Workshop on Forest Monitoring GEO GFOI was to showcase the existing methodologies for early warning deforestation systems and Near Real Time monitoring systems (NRMS) to the Latin American SilvaCarbon countries: Ecuador, Colombia, Peru and Mexico.
The country session included the status and plans of each participating country in developing and implementing Early Warning Systems (EWS) for deforestation. The presentation by the Peruvian officials demonstrated how Terra-i can be used as a tool for land use planning, to assist in decision making for climate change mitigation, forest and biodiversity protection and conservation, ecosystem services assessment, environmental enforcement and other uses.

The EWS session featured presentations of on-going work to development methodologies for improving EWSs using Modis and Landsat data both separately and combined, and the presentations also included commercial alternatives of recent developments that are available on the market.
Terra-i participated in the NRTMS for deforestation detection session, where we showed the system features and methodologies, highlighting the importance of NRTMS tools, such as Terra-i, for assessing deforestation at the regional scale and also as a tool to assist in decision making. The workshop also included a session presenting advances on Fire EWS and developments on fire forecast systems.

The Terra-i team thanks the US SilvaCarbon program and the INPE for the invitation and organization of this regional event. This set of events enhanced the institutions' decision making capabilities using geo-spatial information with the aim of achieving the common purpose of reducing deforestation.

Near real-time vegetation loss detection in Southwestern Ethiopia: calibration, validation, and implementation of the Terra-i system
The Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT) (the Alliance) conducted a training for local stakeholders on the use of Terra-i as part of the collaboration with the Netherlands Development Organisation – SNV in the Coffee Agroforestry and Forest Enhancement for REDD+ (CAFÉ-REDD) Project.
From May 8-12, 2017, the Terra-i team, together with staff from the DGOTA of Peru's Ministry of Environment, carried out the first field validation of vegetative land cover changes detected during Terra-i monitoring for 2016 and 2017, using the technology UAV. This work was carried out under the framework of the project “Sustainable Amazonian Landscapes”. The team carried out over-flights with a Phantom 3 advanced rotor drone and a fixed-wing Ebee drone in seven townships of Yurimaguas. The objective of this work was to recognize the dynamics of land cover and land use changes in the region while at the same time to validate the accuracy of the detections of forest loss being monitored by Terra-i in Yurimaguas.
The Terra-i team has worked hard on renovating Terra-i’s website since early this year. A set of new features on the website provides interactive contents and facilitates adaptation to the mobile devices of our users. The fresh website was developed using the latest update of an open-source, Java-based web system, Magnolia CMS 5.4.4. This update was customized to add different categories of interaction such as news, vegetation cover changes, and information, among others.
Globally more than 1 billion people depend on forests for their livelihoods. Forests play a crucial role in climate regulation, ecosystem services provision and regulation, water supply, carbon storage and many other functions that support biodiversity. Currently the global rate of deforestation is substantial, and there is a growing need for timely, spatially explicit data that flag natural vegetation changes due to human activities.
The latest update of Terra-i has been used with the Co$ting Nature ecosystem services assessment tool to understand the impacts of recent forest loss in Colombia on biodiversity and ecosystem services.
During the 1st and 12th of June 2015, the Terra-i team, together with the Instituto de Investigaciones de la Amazonía Peruana (IIAP) and the Universidad Nacional Agraria La Molina (VLIR-UNALM), conducted the second field validation of the data produced by the Terra-I system. This time, the study area was the Yurimaguas district, Alto Amazonas province, Loreto region (Peru). We used information on populated places, main roads, rivers and information on land cover changes detected for 2013, 2014 and 2015 to define the 65 sampling points (or Terra-I pixels) for the validation process (Figure 1).
