No results found.Understanding the role of forests in the global sustainable development agenda as well as the context of critical environmental and socioeconomic issues related to climate change are relevant aspects for the present day. Water scarcity and ecosystem restoration are major challenges on a local and global scale. This article attempts to address the main aspects of integrated water resources management, climate change and sustainable development in Brazil in recent decades. It is a fact that we need tools for climate-resilient water management approaches for the diverse biomes of the world. An analysis of the current model of the water-climate-forest nexus and an analysis of the integration of policies and governance in Brazil are presented with an emphasis on aspects of water regulation, conservation and restoration of hydrographic basin biomes. In the last two decades, the Southeast and Northeast Brazil are experiencing one of its worst periods of severe drought. Multi-purpose uses reservoirs were constructed to alleviate water shortage problems via redistributing water resources with temporal variability and spatial heterogeneity. Thus, a resilient approach to drought risk management, including reservoir operation methodologies for water scarcity situations, considering reliability, vulnerability and resilience are presented. The applicability of multi-seasonal streamflow generation models for hydrological drought risk evaluation is discussed. Five cases studies of reservoir operation rules as mitigation and adaptation strategies for building a green and resilient future with forests and watershed basins, belonging to three important biomes (savanna, caatinga and Atlantic Forest) are showed: the cases of Paraíba do Sul hydrographic basin (Rio de Janeiro), Cantareira reservoirs system (São Paulo) and the São Francisco river basin systems, including the Interbasin Water Transfer – PISF Project, the Piancó-Piranhas-Açu river basin and the Bocaina reservoir watershed.

ArticleThe social engagement in the forest landscape restoration (FLR): An experience with restoration opportunity assessment methodology in Minas Gerais, Brazil
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The Northern Gualaxo watershed in the Rio Doce basin in Minas Gerais State, Brazil, directly affected by the rupture of the mining tailings dam in 2015, among the actions to mitigation and compensation to reduce the impacts the Renova Foundation has applied the Restoration Opportunity Assessment Methodology (ROAM). ROAM is a toolbox that aims to support forest landscape restoration (FLR) planning process. The approach includes the engagement of local actors through discussions about motivation factors to join FLR efforts and the current situation of enabling conditions in the territory. All the analysis conducted under the ROAM application process had been validated by stakeholders and though these activities the governance local has strengthened. The results identified that income generation, water quality improvement and engagement were the three main motivational factors. From that, a spatial analysis identified the estimated areas that could support each of this factors that could support the establishment of the priorities in a land use planning process in the region. Also, based on the collective discussions the main identified gaps to implement FLR activities were the products commercialization, technical assistance, social engagement, and scalability. Based on this experience, strategies for solutions are being proposed and implemented in order to provide an enable environment FLR agenda with a strong social engagement in the process.

DocumentVariability in the early growth of Parkia timoriana (DC.) Merr. from Mount Makiling Forest Reserve, Luzon, Philippines and its applications in conservation and forest restoration

No results found.This study evaluated the early growth performance of selected mother trees of Parkia timoriana (Fabaceae) and characterized the suitable environmental (soil and light) factors for the growth of the species. P. timoriana seedlings from different mother trees from the Mount Makiling Forest Reserve (MMFR), Luzon, Philippines were grown in two soil media under greenhouse condition and field trial planted in the University of the Philippines Laguna-Quezon Land Grant (LQLG), where P. timoriana is not occurring naturally and soil and climate differ significantly with the MMFR. Early growth performances in height and ground basal diameter (GBD) or root collar diameter (RCD) both in the greenhouse and field trial plot were measured. Nursery-based performance showed that the average RCD was generally higher in MMFR than LQLG soil but the overall difference was not statistically significant. In contrast, overall average height was consistently higher in LQLG than in MMFR soil, but similar to RCD the difference was not statistically significant. Under different light conditions in the field trial, there was significant difference in mortality, tree height, and GBD. The differences in both the height and GBD may be attributed to the genotype of the mother trees, but height can additionally be attributed to the interaction of the genotype and the different light conditions. Results suggest that P. timoriana can be grown in areas of different soil condition, but it requires partial shade in order to achieve its full growth potential during the early stage of its growth. Hence, P. timoriana when used in reforestation or tree planting projects must consider differences in the early growth response of seedlings according to its genotype as well as light conditions. However, it is highly suggested that growth performances among provenances of P. timoriana and other environmental variables that may affect growth of the species should be looked into.
