Soil erosion as a resilience drain in disturbed tropical forests

Soil erosion as a resilience drain in disturbed tropical forests

Tropical forests are threatened by intensifying natural and anthropogenic disturbance regimes. Disturbances reduce tree cover and leave the organic topsoil vulnerable to erosion processes, but when resources are still abundant forests usually recover. Across the tropics, variation in rainfall erosivity – a measure of potential soil exposure to water erosion – indicates that soils in the wetter regions would experience high erosion rates if they were not protected by tree cover. However, twenty-first-century global land cover data reveal that in wet South America tropical tree cover is decreasing and bare soil area is increasing. Here we address the role of soil erosion in a positive feedback mechanism that may persistently alter the functioning of disturbed tropical forests. Based on an extensive literature review, we propose a conceptual model in which soil erosion reinforces disturbance effects on tropical forests, reducing their resilience with time and increasing their likelihood of being trapped in an alternative vegetation state that is persistently vulnerable to erosion. We present supporting field evidence from two distinct forests in central Amazonia that have been repeatedly disturbed. Overall, the strength of the erosion feedback depends on disturbance types and regimes, as well as on local environmental conditions, such as topography, flooding, and soil fertility. As disturbances intensify in tropical landscapes, we argue that the erosion feedback may help to explain why certain forests persist in a degraded state and often undergo critical functional shifts.

Bernardo Strassburg is one of the leader authors of the new report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)

Nature is declining globally at rates unprecedented in human history — and the rate of species extinctions is accelerating, with grave impacts on people around the world now likely, warns a landmark new report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the summary of which was approved at the 7th session of the IPBES Plenary, meeting last week (29 April – 4 May) in Paris. The report has two major main messages. On the one hand, it shows a tragic picture of the devastation of the planet’s nature and the enormous negative consequences of this devastation for human well-being. On the other hand, based on multiple scientific studies and practical success stories, it illuminates ways to reverse this situation and at the same time achieve a state of equilibrium in our relationship with the rest of nature and the major sustainable development goals that humanity has set for itself. It brings out the warning of the catastrophic situation and the ways out of it. “The overwhelming evidence of the IPBES Global Assessment, from a wide range of different fields of knowledge, presents an ominous picture,” said IPBES Chair, Sir Robert Watson. “The health of ecosystems on which we and all other species depend is deteriorating more rapidly than ever. We are eroding the very foundations of our economies, livelihoods, food security, health and quality of life worldwide.” The Brazilian researcher Bernardo Strassburg, IIS´s Executive Diretor, Professor at the Pontifical Catholic University of Rio de Janeiro (PUC-Rio) and coordinator of the the Centre for Conservation and Sustainability Science (CSRio)  is one of the leader authors of the assessment. His main contributions focused on the fifth chapter, on possible ways out of today’s dire situation for a sustainable future. The main message is that only with transformative changes, coordinated within different sectors we will achieve a sustainable future. “The good news is that we do not need any new invention, all the elements needed for the transition to sustainability are already being implemented successfully in several regions of the planet, albeit on a small scale and in isolation,” stresses Strassburg. Among the several proven measures are the expansion of protected areas and indigenous lands, an integrated spatial planning that reconciles areas for agricultural production, areas for conservation and areas for nature restoration. These elements were illustrated in the report with Brazilian success stories, which have already led to the largest deforestation reduction the world has seen in a short time (in the Amazon between 2005 and 2012) and the remarkable experiences that combine production, conservation and restoration. “These Brazilian examples of success stories in the global report reinforce our unique potential to lead the world in a transition that reconciles protection to nature and its multiple contributions to us with sustainable rural development and an international differential. For the agricultural sector, such a scenario will avoid the current degradation of soils, water resources and pollination, while at the same time positioning Brazilian agribusiness in the leadership of green agriculture, which is already becoming a requirement in large consumer markets “, concludes Strassburg. “The member States of IPBES Plenary have now acknowledged that, by its very nature, transformative change can expect opposition from those with interests vested in the status quo, but also that such opposition can be overcome for the broader public good,” Watson said. The IPBES Global Assessment Report on Biodiversity and Ecosystem Services is the most comprehensive ever completed. It is the first intergovernmental Report of its kind and builds on the landmark Millennium Ecosystem Assessment of 2005, introducing innovative ways of evaluating evidence. Compiled by 145 expert authors from 50 countries over the past three years, with inputs from another 310 contributing authors, the Report assesses changes over the past five decades, providing a comprehensive picture of the relationship between economic development pathways and their impacts on nature. It also offers a range of possible scenarios for the coming decades. In addition to Strasssburg, contributed to the study IIS´s Executive Director, Professor at the Pontifical Catholic University of Rio de Janeiro (PUC-Rio) and coordinator of the the Centre for Conservation and Sustainability Science (CSRio)  Agniezka Latawiec and IIS´s research assistant Fernanda Tubenchlak. Based on the systematic review of about 15,000 scientific and government sources, the Report also draws (for the first time ever at this scale) on indigenous and local knowledge, particularly addressing issues relevant to Indigenous Peoples and Local Communities. The Report finds that around 1 million animal and plant species are now threatened with extinction, many within decades, more than ever before in human history. The average abundance of native species in most major land-based habitats has fallen by at least 20%, mostly since 1900. More than 40% of amphibian species, almost 33% of reefforming corals and more than a third of all marine mammals are threatened. The picture is less clear for insect species, but available evidence supports a tentative estimate of 10% being threatened. At least 680 vertebrate species had been driven to extinction since the 16th century and more than 9% of all domesticated breeds of mammals used for food and agriculture had become extinct by 2016, with at least 1,000 more breeds still threatened. To increase the policy-relevance of the Report, the assessment’s authors have ranked, for the first time at this scale and based on a thorough analysis of the available evidence, the five direct drivers of change in nature with the largest relative global impacts so far. These culprits are, in descending order: (1) changes in land and sea use; (2) direct exploitation of organisms; (3) climate change; (4) pollution and (5) invasive alien species. The Report notes that, since 1980, greenhouse gas emissions have doubled, raising average global temperatures by at least 0.7 degrees Celsius – with climate change already impacting nature from the level of ecosystems to that of genetics – impacts expected to increase over the coming decades, in some cases surpassing the impact of land and sea use change and other drivers.

Sustaining the earth from the bottom up: developing a conceptual model for valuing ecosystem services for tropical soils

Sustaining the earth from the bottom up: developing a conceptual model for valuing ecosystem services for tropical soils

Soils provide the basis for food production and help to control the damaging consequences of climate change by regulating greenhouse gases and water. Nevertheless, soil remains a neglected resource by governments and, consequently, farmers and decision-makers underestimate its value. Brazil has an abundance of agricultural and forest areas, which is fundamental for global food security and climate regulation. While vast areas are being deforested, agricultural areas also suffer from overexploitation and inadequate soil management, which leads to the degradation of this natural resource. For example, livestock is one of the leading agricultural activities in the country; however, the majority (75%) of the areas under pasture is degraded. In this context, the project ‘Sustaining the land from the bottom up: developing soil carbon and soil ecosystem services valuation frameworks for tropical soil’ aims to show the importance of soil ecosystem services for ecosystems functionality, the food chain and sustainable land management. The project includes environmental analyses of pasture data; base on the results, soil services will be valued. Subsequently, we will inform and translate scientific results for decision-makers, that is, farmers and public policymakers. The dialogue between science, society and politics has the potential to contribute to the improvement of soil management in Brazil and worldwide. The project is coordinated by Agnieszka Latawiec, who is also the coordinator of CSRio. ‘This project is also an opportunity to show how natural and social sciences should integrate and collaborate to benefit land use, explains Agnieszka, who is also a professor at the Department of Geography and Environment at PUC- Rio and executive director of the International Institute for Sustainability (IIS). The project is funded by the Newton Fund Advanced Fellowship, Royal Society (U.K.), the Carlos Chagas Filho Foundation for Research Support in the State of Rio de Janeiro (FAPERJ), the National Council for Scientific and Technological Development, and the Pontifical Catholic University of Rio de Janeiro (PUC-Rio). The project is being conducted through three work packages that are linked to its main objectives. 1. A systematic review of soil ecosystem services in tropical regions The theme of soil ecosystem services emerges as an innovative approach with the potential to contribute to reducing the process of soil degradation. It encourages better communication of scientific results to decision-makers, supporting a more reliable connection between science and politics. Exploring the theme of soil ecosystem services in the tropical region is important because i) important forest landscapes are located in countries in this region, such as Brazil and Indonesia, and consequently can suffer a lot from processes of deforestation and soil degradation; ii) includes leading countries in the production of agricultural products; III) includes the poorest countries and, therefore, the most vulnerable populations regarding social and environmental injustices. Studies that seek to contribute to the understanding the current scenario and guide efforts for the next researches in the tropical region are urgent and necessary, as it is through soil conservation measures that we will guarantee the functioning of ecosystems. 2. Evaluation of soil ecosystem services, modelling and valuation of experiments with different methods of forage management and forest restoration in Brazil One of the biggest challenges regarding soil ecosystem services is modelling and evaluation, as both topics are rarely addressed in publications. During the workshops discussions among project’s participants and collaborators, allowed us to move forward in knowledge on these topics. After research on the necessary data, a field protocol will be developed to assess some of the soil ecosystem services. Also, we will perform respirometry, and analyse the soil’s water retention capacity. We will analyse the data obtained in the field experiment, and add details of the proposal in the seedling and pasture experiment. Data will be obtained from a two-year experiment (2016 – 2017) on the impact of different management methods (such as liming, fertiliser, biochar and legumes) on soil quality and forage productivity. The experiment involved 80 experimental plots with three different tropical forage grasses in multiple crop cycles and provided a robust data set that will be used, in a pioneering way, to propose new approaches to evaluate the SES. The SES will initially be classified according to the Millennium Ecosystem Assessment (MEA, 2004), as proposed by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), and by other models that emerge during the first stage of the research. Then, the most appropriate evaluation option will be chosen based on the existing literature and the contribution of stakeholders. 3. Collection, exchange and dissemination of knowledge at the science-public policy interface The results will be disseminated to scientific and non-scientific audiences through workshops and other activities of knowledge exchange and communication on soil ecosystem services. We believe that this is necessary for the framework to contribute to better soil management. Finally, we will present recommendations on soil valuation methodology and propose the inclusion of SES in the context of Brazilian public policies. We held four workshops until August 2020, two in Brazil and two in England. In June 2019, we carried out an environmental education activity using an active learning method at a school in Rio de Janeiro. We introduced the concepts of environmental resource management, the tragedy of common goods, inflexion point and reproduction rate. We conducted a review on soil ecosystem services in public policies in Brazil, which we presented at the third workshop, held at PUC-Rio, in October 2019. The network of collaborators was expanded, and we are developing a communication strategy with decision-makers. In 2021, we will perform interviews and workshops with policymakers, experts who lead the knowledge exchange process about SES and with farmers. Project-related publications: • Latawiec, A.
