Finished the mapping of permanent preservation areas throughout the impacted area from the Fundao dam to Candonga. This study, which followed in detail the guidelines of the Forest Code, addresses the qualification of the mapping carried out after the collapse. The identification of the tributaries and springs was done initially by means of satellite images and, soon after, measured by the field teams. This way, in addition to repairing the damage caused, it will be possible to define the areas on impacted properties that are subject to environmental regularization. Based on this material, the planning for forest restoration in these areas will be carried out in a more objective manner and there will be direct communication with the rural producer and bodies responsible for approving the actions of the Renova Foundation.
On 01/22 and 01/23, technical visits were made by companies in order to contract services for vegetable gardens and orchards. The scope of the contracts was divided into 2 parts: Package 1 - Mariana; and Package 2 - Barra Longa, Rio Doce, Ponte Nova, S. C. do Escalvado and Backyards of Barra Longa. The technical visit has the objective of aligning the specifications of the services to be executed with the candidate companies as a way of guaranteeing the quality of the contracting, avoiding delays in the execution of the services.

In December/2018, the closing date was reached for receiving proposals from public and private institutions interested in participating in the Tender ATER Sustainability - Resumption of Agricultural and Livestock Activities. The Technical Assistance and Rural Extension (ATER) actions will support the process for resuming agricultural activities on affected properties, according to clause 125c of the Transaction and Conduct Adjustment Term (TTAC). The Tender was developed in partnership with the State Secretariat for Agrarian Development (SEDA) and the Technical Board of Economy and Innovation of the Interfederative Committee (CIF).

The product was ranked among 8 finalists of the WWF-sponsored Environmental Challenge and was granted some of the world's top design awards.
On 12/19/2018, the SAF (Agroforestry Systems) Implementation Workshop took place. The workshop was conducted in an Communal Work format to launch the first SAF Demonstration Unit of the “Renewing the Landscape” project. The goal is to teach techniques for restoring forests and degraded areas by planting multiple crops together with tree species.
On 12/05/2018, a training session was held on Agroecological Vegetable Gardens. The course was taught by the rural producer Waldir Pollack, affected by the Fundao dam collapse, with the objective of teaching sustainable practices of organic agriculture. The classes take place on his property in the community of Paracatu de Cima (MG) on a bi-weekly basis.

The actions of these Programs are being reported in an integrated way among the environmental programs: 17 (Resumption of Agricultural Activities), 25 (Recovery of Environmental Area 1) and 40 (Promotion of CAR and PRA), due to the simultaneous repair and improvement actions on the same rural properties impacted by the Fundao dam collapse.

In November, forest restoration began in Front 4 (Rio Doce, Ponte Nova and Santa Cruz do Escalvado).
Furthermore, technicians of the Renova Foundation were invited for interviews by several communication channels, such as Jornal Nacional, Jornal Hoje, Band SP, Band MG, NBR, Radio Itatiaia, etc. The great demand for information came with the 3-year mark of the Fundao dam collapse.
On 11/08, the tender for research projects was launched in partnership with the Foundations for Supporting Research of the States of Minas Gerais and Espirito Santo (FAPEMIG and FAPES), seeking the implementation of actions to produce knowledge associated with the second round of economic losses recovery, social and environmental consequences of the collapse of the Fundao dam in Mariana (MG).
On 11/13, a SAFs (Agroforestry Systems) course was organized by WRI, which aims to teach techniques for restoring forests and degraded areas by multiple cropping with tree species.
Between 11/21 and 11/23, the Second Brazilian Conference on Ecological Restoration took place in Belo Horizonte, organized by SOBRE (Brazilian Society for Ecological Restoration) where several works by UST were presented.

The actions of these Programs are being reported in an integrated way among the environmental programs: 17 (Resumption of Agricultural Activities), 25 (Recovery of Environmental Area 1) and 40 (Promotion of CAR and PRA), due to the simultaneous repair and improvement actions on the same rural properties impacted by the Fundao dam collapse.

In October, training courses were offered in Mariana on organic horticulture for 17 people. The main objective of the initiative is to generate alternative income production and strengthen family farming on farms. Producer Waldir Pollack, hired by the Renova Foundation, taught 2 courses in October (10/24 and 10/31) on this topic.
The forest restoration process was started in Front 3 (Barra Longa) and Front 4 (Ponte Nova, Rio Doce and Santa Cruz do Escalvado), already resulting in field visits and soil sampling analysis.
End October, the registration process for the second ATER Sustainability Tender - Resumption of Agricultural and Livestock Activities, developed in partnership with the State Secretariat for Agrarian Development (SEDA) and the Technical Board of Economy and Innovation of the Interfederative Committee (CIF). The objective is to support the process of environmental readjustment and the application of sustainable production practices on rural properties affected by the Fundao dam collapse, within the range of the municipalities of Mariana, Barra Longa, Santa Cruz do Escalvado, Ponte Nova and Rio Doce. Registration for the Tender goes until the beginning of December. Public and private institutions may participate.
In October, the first evidence of natural regeneration was obtained in the Doce River basin in the areas affected by the tailings. With the results of an experiment carried out by the partnership between the Federal University of Vicosa and the Renova Foundation, a greater predominance of pioneer species was observed in mud-affected environments compared to reference environments.
In addition, 25 retention basins were constructed and 333 soil samples were collected in October.

The actions of these Programs are being reported in an integrated way among the environmental programs: 17 (Resumption of Agricultural Activities), 25 (Recovery of Environmental Area 1) and 40 (Promotion of CAR and PRA), due to the simultaneous repair and improvement actions on the same rural properties impacted by the Fundao dam collapse.

On 08/27, the contracting process started for the Productive Restructuring of impacted properties in the Municipalities of Mariana, Barra Longa, Rio Doce, Ponte Nova and Santa Cruz do Escalvado. The contractor will act in managing the pasture of these producers, increasing soil fertility and productivity, being one of the main vectors of the Resumption of Agricultural Activities. These activities are scheduled to end in March 2020.

On 08/24, the contracting process started for the Forest Restoration services on properties impacted in the municipalities of Barra Longa, Rio Doce, Ponte Nova and Santa Cruz do Escalvado (fronts 3 and 4). The contractor will act in the Environmental Recovery of these properties, with a total of 495 hectares to recover. It is worth noting the efficient negotiation, in which a reduction of approximately 20% in the cost per hectare was achieved in relation to the contract in February for fronts 1 and 2 (Mariana and Barra Longa). It is expected that the contractor will start activities by: 09/24.

On 08/23, a theoretical course on Agroforestry Systems was held in Barra Longa for those affected and interested in becoming one of the five Demonstration Units on this topic. Ten affected individuals were trained, in addition to those from the Renova team. On 08/29, there was an exchange program on a model farm located in Araponga/MG to continue the training of these stakeholders. The Demonstration Units are a key delivery of the Resumption of Agricultural and Forest Restoration programs, as they promote training and exposure to technologies for diversification of the local economy.

From July 16 to 18, awareness-raising workshops were held in the municipalities of Mariana, Barra Longa and Rio Doce. These workshops, attended by approximately 80 affected rural producers, have the objective to motivate families to adhere to sustainable production technologies for the Resumption of Agricultural Activities and setting up SAF Demonstration Units (agroforestry systems), Silviculture of Native Species and Ecological Pastures.

Also through the Renewing Landscapes Project, on July 26 and 27, two other workshops were held with local leaders for identifying critical success factors and mapping of parties associated with landscape restoration, part of the ROAM application (forest restoration analysis methodology) in the territory of the extended Gualaxo do Norte.

In July, emergency support was initiated for producers of the Pequeno River/Juparana Lagoon. Due to the flooding of the region in front of the barrier constructed for preventing the possible entry of tailings material, pasture lease is underway for the relocation of cattle from rural producers in the region. Still as part of this emergency action, provision of silage and fence material for sheep farmers.

We already issued 197 PASEA and completed 207 Sustainability Assessments (ISA) for 236 eligible properties, of which 228 have an active Rural Environmental Registry and 179 have already been rectified; 72.0 hectares of forest have been restored from a total of 647 hectares that might be reforested; 21,186 tons of silage were delivered to impacted producers; 2,666 hours of technical assistance and rural reach were provided for 166 properties.

In June, a specialist in Geographic Information Systems joined the Sustainable Land Use team. He became responsible for the organization, standardization, publication and generation of indicators from the geographic data collected by the various disciplines.

This professional will rotate through several areas, supporting the planning process for the contracting of services that involve the generation of spatial data, as well as the use of this information to ensure the definition of indicators and the monitoring of the Sustainable Land Use actions. It will also apply geotechnologies for the use of the field teams, which will contribute to the agility in the execution of all these steps to increase the quality of the information generated.

This change will also bring positive impacts for the elaboration of projects resulting from the solutions defined in the Socioeconomic and Environmental Adequacy Plan (Pasea), which is focused on reparatory actions and the Individual Property Project (IPP), for those properties that are being compensated through the programs. This is because the change will allow the monitoring of its evolution through an online platform, meeting the new demands of the governance of the Foundation, public agencies and civil society.

This program’s actions are reported in the section dedicated to Program 17, which deals with the integrated action between socioenvironmental and socioeconomic initiatives to repair and adapt rural properties impacted by the collapse of the Fundao dam.

A partnership was approved with the Federal University of Ouro Preto (UFOP) for sample collection and comparative analysis of the presence of trace metals in the soil, in wildlife that feed on the flowers, and the parts that we consume as food (bioavailable fraction). The results of these studies will provide answers on the toxicity of the tailings and its possible effects on the food chain.

These studies will also serve as a basis for research on ecological risks and human health, which will be conducted by the Renova Foundation. The first stage of this activity are the field expeditions to collect samples.

In March, fencing activities of the Permanent Preservation Areas (PPAs) started for the forest restoration of lots 3 and 4 (Barra Longa to Rio Doce). This action deals with the execution of preliminary services for planting activities, which is scheduled to start in October 2018.

An agreement was signed with the Federal Universities of Minas Gerais and Vicosa (UFV/UFMG) to begin technical/scientific monitoring of forest restoration. The scope of the agreement involves technical guidance for adaptation, implementation of alternative ecological restoration techniques, as well as assisting in the monitoring and definition of the indicators.

The program has filed a report with the CIF and the Forestry Technical Board on the completion of the regulation works on channels, banks and of erosion control of the Gualaxo do Norte, Carmo and Doce Rivers. In addition, it signed an agreement with the Federal University of Vicosa (UFV) for technical/scientific monitoring of the forest restoration.

It continued the maintenance of the bioengineering works for the rainy season and carried out the fourth campaign to monitor the erosion control and rehabilitation of tributaries/main channel between the Fundao and Candonga.

It started the forest restoration work on fronts 1 and 2 (Mariana and Barra Longa, Minas Gerais) and presented the report in response to phases 3 and 4 of the WATU operation, carried out by the State Department of Environment and Sustainable Development (SEMAD), to support the actions of the Renova Foundation for environmental recovery.

Whereas the restoration contracting process of fronts 3 and 4 is under analysis by the Renova sourcing sector.

In January, the program continued the activities for fencing the Permanent Preservation Areas (PPA's) that will be recovered, including the main river channel PPAs, forest fragments and springs in the municipality of Mariana (MG). So far, 36.8 km of fences have been installed on 55 affected rural properties.

Bioengineering maintenance services were also carried out in the tributaries classified as G02, G03 and G04, in compliance with the Ibama report on Phase IV of Operation Augeas. To ensure the quality of these bioengineering services, and others already completed, and to verify the need for new interventions, Renova is continuously monitoring the field.

In January, priority areas 7 and 15 underwent detailed corrective maintenance including the following services: shredding, riprap and revegetation. The maintenance of the areas is programmed until stability is guaranteed, taking as a reference the pre-collapse situation.

The completed tributaries are also undergoing maintenance. For tributaries without access, or with difficult access, monitoring is being performed by aerial images (UAV and drones) to follow the process of natural regeneration.

Another vegetation monitoring campaign, via aerial imaging, is being carried out by Geopixel.

Forest restoration activities started in the Mariana and Barra Longa region of Minas Gerais with kick-off meetings with Emflortec and Agroflor. Also, in Barra Longa (MG), the team visited properties for the selection of Demonstration Units of Ecological Pasture, for reforestation with low-cost native trees (Verena Project) and agroforestry systems. The same work is being done in Santa Cruz do Escalvado (MG).

The teams of this program carried out the fencing of the Permanent Preservation Areas (PPAs) to be recovered, including those of main river channels, part of forests and springs on 37 rural properties of the municipality of Mariana (MG).

In the non-priority areas 19, 25 and 27, the erosion control works and the regularization of river channels and banks were completed. The activities carried out in these areas included the conformation of soil, restoration of drainage systems, dibbling, fertilization, manual sowing and application of biodegradable blankets and sediment retainers.

Priority areas 15A and 15B and non-priority areas 21 and 22A underwent corrective maintenance through dibbling, sowing, fertilization and irrigation. The completed tributaries are also going through the maintenance process.

Technicians of the program conducted field trips during the 3rd intervention monitoring campaign. The release of the results is scheduled for April 2018.

The Permanent Preservation Areas (PPAs) to be recovered in the municipality of Mariana (MG), including main river channels, forest fragments and springs, were fenced. So far, 17 km of fences have been installed on 37 affected rural properties.
Work was done in areas 19, 25 and 27, non-priority, to regularize channels and banks and for erosion process control. The activities underway in these areas include soil conformation, drainage systems restitution, dibbling, fertilization, manual sowing, as well as application of biodegradable blankets and sediment retainers.
To ensure the quality of bioengineering services, field monitoring was performed to verify the efficiency of the activities performed and the need for interventions. In areas where plant coverage and erosion process containment systems do not meet the criteria of the technical specification, whether due to natural non-development or due to owner interventions (such as cattle trampling), timely maintenance of bioengineering services will be scheduled. There is currently a company full time involved with these services.
In November, areas 15A, 15B (priority areas), 21 and 22A (non-priority areas) underwent corrective maintenance, such as dibbling, sowing, fertilization and irrigation.
The completed tributaries also go through this maintenance process and those without access are monitored by aerial images (VANT and Drones) to verify the natural regeneration process. In November, another campaign was carried out to monitor the vegetation, through aerial images captured by the company Geopixel.
The hiring process of the companies to carry out the services of Forest Restoration and Fencing of PPAs in Barra Longa, Ponte Nova, Santa Cruz do Escalvado and Rio Doce (MG) also moved forward in November.

In Mariana (MG) the fencing activities of the Permanent Preservation Areas (APP) are ongoing. So far, 10.2 km of fence has been installed on 19 affected rural properties.

Works to regulate river channels and banks and control erosive processes in the non-priority areas 19, 25, and 27 are ongoing. The activities underway in these areas include soil conformation, drainage systems restitution, dibbling, fertilization, manual sowing and application of biodegradable blanket and sediment retainers.

Renova monitored the efficiency of the activities carried out and the verification of the need for interventions to guarantee the quality of bioengineering services. In areas where the covering of plants and erosion process containment systems do not meet the criteria of the technical specification, regular maintenance of bioengineering services is scheduled. Currently, there is a company providing these services full time. In October, priority areas 3, 5, 6, 7, 8, 10, 11, 13 and 15 and non-priority areas 19, 23 and 24 went through regular corrective maintenance such as dibbling, seeding, fertilization and irrigation.

The completed tributaries also go through the maintenance process. Those without access are monitored by aerial images (VANT and Drones) to monitor the natural regeneration process. In October another vegetation monitoring campaign was started, via aerial images carried out by the company Geopixel.

The third campaign to collect information on the monitoring of priority interventions was completed, which will allow the evaluation of the effectiveness of the environmental recovery interventions carried out in the stretch between the S4 dam and the Candonga reservoir.

Initiation of the fencing activities of the Permanent Preservation Areas (APP) to be reforested as of December 2017.

The activities of soil conformation, drainage systems restitution, making holes for planting, fertilization, manual sowing and application of biodegradable blanket and sediment retainers in non-priority areas are still underway.

In areas where the covering of plants and erosion process containment systems do not meet the quality criteria, whether because there is no natural development of the vegetation or because of interventions, such as trampling of cattle, timely maintenance of bioengineering services will be scheduled. Currently, the company that’s responsible is fully focused on these services.

The completed tributaries will also go through the maintenance process and the areas that are difficult to access are being monitored by aerial images (Satellites and Drones) to follow the process of natural regeneration.

The working plan, to comply with Clause 160 of the Transaction and Conduct Adjustment Term (TTAC), was presented to the Inter-Federative Committee (CIF) and is aimed at the reconformation of the channels, banks and erosion control in the rivers Gualaxo do Norte, Carmo and Doce in the municipalities of Mariana, Barra Longa, Rio Doce and Santa Cruz do Escalvado, in Minas Gerais.

The environmental rehabilitation activities were completed in the non-priority areas, with the topographic reconformation of the channels and flood plains of the main rivers, as well as revegetation, surface drainage and erosion process control. The non-priority areas were defined based on the geomorphology study that indicated the sites with lower tailings deposition and/or less environmental fragility.

These actions seek to avoid new loads of sediments from the river banks to the river channel and its tributaries, through measures of control of drainage, rockfall and bioengineering. To ensure the establishment of revegetation, the areas will also be preserved by using top dressing and reseeding methods.

The works to regulate river channels and banks and control erosive processes in the non-priority areas 19, 21, 25, 26 and 27 are in progress. At these locations, tailings volumes are relatively small, representing less risk. Immediate access to these points is more difficult because of the small flood plains. The activities underway in these areas include soil conformation, drainage systems restitution, making holes for planting, fertilization, manual sowing and application of biodegradable blanket and sediment retainers.

The areas with completed works are periodically monitored to demonstrate the efficiency of the activities performed and to identify sites in need of maintenance.

The Renova Foundation presented to the Technical Board for Forestry Restoration and Water Production (CTFLOR) the working plan for the recovery of 2 thousand hectares in environmental area 1.

Completion of environmental rehabilitation activities in priority areas. Topographic reconformation of the main river basins and plains, as well as revegetation, surface drainage and erosion process control. The works to regulate channels and banks and control of erosive processes in non-priority areas are in progress.

Monitoring of the areas with completed works with the purpose of demonstrating the efficiency of the activities performed and identifying sites that need maintenance.

Completion of aerial survey of vegetation by means of drones. With the aim of quantifying the revegetation area and biomass above ground, the initiative will provide the data needed for the second campaign of the Priority Intervention Monitoring Plan.

Preparation has started of the working plan for the recovery of two thousand hectares in the environmental area 1, which will be approved by the Inter-Federative Committee (CIF).

In June, the environmental rehabilitation activities of the 101 mapped impacted tributaries were completed. The topographic reconformation of the channels and plains of the main rivers, as well as revegetation, surface drainage and erosion process control were completed in all 16 priority areas, defined based on the geomorphology study, which indicated the sites with the highest deposition of tailings and/or greater environmental fragility. The actions seek to avoid new loads of sediments from the river banks to the river channel and its tributaries, through measures of control of drainage, rockfall and bioengineering.

Work has begun on the reconformation of channels and margins in three non-priority areas. In these locations, tailings volumes are relatively small, representing less risk. In addition, immediate access to these points was more difficult because of the small flood plains.

In May, another 16 tributaries were recovered, reaching 98 watercourses (tributaries), out of a total 101 mapped.

The actions seek to avoid new loads of sediments from the river banks to the river channel and its tributaries, through measures of control of drainage, rockfall and bioengineering. In order to ensure the establishment of revegetation, the areas will be maintained using top dressing and reseeding methods, when necessary.

Work has begun on the reconformation of channels and margins in non-priority areas. In these locations, tailings volumes are relatively small, representing less risk. In addition, immediate access to these points was more difficult because of the small flood plains.

In April, eight other tributaries were recovered, reaching 82 watercourses, out of the total 101 mapped. In the priority areas of Gesteira, Paracatu de Cima, Ponte do Gama and Bicas, erosion control services were carried out.

Ongoing are the development of engineering projects in non-priority areas and the recovery actions in priority areas, including services of channel regulation and embankment and control of erosion processes in the Gualaxo do Norte, Carmo and Doce rivers.

In March, another 4 tributaries were recovered, reaching a total of 74 recovered tributaries of the 101 mapped. Ongoing are the development of engineering projects in non-priority areas and the recovery actions in priority areas, including services of channel regulation and embankment and control of erosion processes in the Rivers Gualaxo do Norte, Carmo and Doce. In total, 921 people were mobilized by the actions of the program.

935 employees were involved in the activities related to environmental recovery. There was a 65% progress regarding the environmental recovery services of the priority areas and a 67% progress regarding the environmental recovery services of the tributaries. 15 tree species have been planted on 78 sites across the Permanent Preservation Areas (PPAs), in addition to the implementation of 579 plots of vegetation to assess the percentage of actual covering vegetation. Finally, 45 rulers for sediment accumulation monitoring have been installed in several priority areas.

From January 2016, 63 tributaries were recovered and 52% of channel reconformation works and erosion control works of the priority areas were executed. The revegetation pilot test with native species was initiated in impacted permanent preservation areas, in addition to the issuance of recovery projects of the non-priority areas.

The report of the long-term leaching tests confirm that it is unlikely that the soil and affected sediment release high concentrations of metals into the ground water in submerged conditions or during bad weather exposure conditions. Because of their low content of trace metals and their more crystalline nature, the tailings possibly don’t contribute significantly to the further mobilization of metals.

Whereas the evaluation report of the metal presence in floodplains shows that it is likely that the soils affected by the tailings are suitable for agricultural production of crops that are more tolerant of these metals (As, Co, Mn and V), such as cotton, Nile grass and potato and native plants for the revegetation of the area and restoration of the natural ecosystem. Precautions should be taken to produce crops such as rice, barley, radish and soybean in the area where arsenic and manganese in the soil exceed the Ecological Soil Indicators for plants. High concentrations of these elements in the soil of the affected flood plains are largely due to the type of soil of the basin or the local geology. Evidence indicates that arsenic, cobalt, manganese and vanadium concentrations are relatively low in the tailings samples collected in the Fundão tailings dam, as shown in the Golder report (2016).

From January 2016, 60 tributaries were recovered and 52% of channel reconformation works and erosion control works of the priority areas were performed. Such areas now also include monitoring structures. Furthermore, the development of projects for non-priority areas has begun, as well as maintenance to the initial emergency revegetation of 800 hectares. Leaching tests were performed to simulate different depositional environments for 20 weeks. Such tests help the Renova Foundation to understand the chemical stability of the materials deposited downstream of the Fundão tailings dam and in different deposition areas in the long run. The results confirm that it is unlikely that the affected soil and sediment release high concentrations of metals into the ground water in submerged conditions or during bad weather exposure conditions. Because of their low content of trace metals and their more crystalline nature, the tailings possibly don’t contribute significantly to the further mobilization of metals. According to the Evaluation Report of Metal Presence in Floodplains, it is likely that the land affected by the tailings in floodplains are suitable for agricultural production of crops which are more tolerant to such metals, such as Nile grass, potatoes and also native plants to be used in revegetation of the area and restoration of the natural ecosystem. Precautions should be taken for the production of crops such as rice, barley, radish and soybean in the area where arsenic and manganese in the soil exceed the Ecological Soil Indicators for plants.

From January to November, 60 tributaries were recovered and 48% of channel reconformation works and erosion control works of the priority areas were performed.

Precautions should be taken for the production of crops such as rice, barley, radish and soybean in the area where arsenic and manganese in the soil exceed the Ecological Soil Indicators for plants.

In October, the recovery of a tributary, the detailing of bioengineering activities in the priority areas and the preparation of a technical manual for the standardization of the drainage works were completed. In the same period, data were made available on the WebGis of environmental agencies (tool that allows the integration of spatial geo-referenced and tabular information and make them available for interactive query).

56 tributaries have been completed, as well as the alignment with environmental organizations about the solutions to be implemented in the reconformation works on the river channels.
