Perception-Based Study on the Value of Nature to People and Land Sparing for Nature in Brazil and Poland

Perception-Based Study on the Value of Nature to People and Land Sparing for Nature in Brazil and Poland

Understanding perception about nature is paramount to understanding human behavior and decision making on the environment. It was performed a survey-based study in Brazil and Poland to better understand the perception of land sparing for nature and the perceived value of nature. The countries were selected by intentional sampling and given their importance for local and global biodiversity conservation, and complex socio-ecological context of conservation versus agroforestry business. It was applied an online questionnaire (N = 1030) in Brazil and face-to-face interviews in Poland (N = 322). Brazilian respondents demonstrated more pro-environmental attitudes than Polish survey participants. Regarding the question: “How much nature that is left should be spared?”, nearly 51% of Brazilians answered “everything”, compared with 13% of Polish respondents. Just under half of the respondents from Poland (45.6%) indicated that half of the nature that is left should be spared. Brazilian respondents also perceived the intrinsic value of nature to a greater extent compared with Polish respondents; in total, 76% of Brazilians respondents entirely agreed that “Nature, its plants and animals have a value on their own, independent of their usefulness for us” versus 25% of Polish respondents. Our study contributes to a better understanding of the leverage points driving pro-environmental attitudes in both countries.

Set ambitious goals for biodiversity and sustainability

Global biodiversity policy is at a crossroads. Recent global assessments of living nature and climate show worsening trends and a rapidly narrowing window for action. The Convention on Biological Diversity (CBD) has recently announced that none of the 20 Aichi targets for biodiversity it set in 2010 has been reached and only six have been partially achieved. Against this backdrop, nations are now negotiating the next generation of the CBD’s global goals [see supplementary materials (SM)], due for adoption in 2021, which will frame actions of governments and other actors for decades to come. In response to the goals proposed in the draft post-2020 Global Biodiversity Framework (GBF) made public by the CBD (5), we urge negotiators to consider three points that are critical if the agreed goals are to stabilize or reverse nature’s decline. First, multiple goals are required because of nature’s complexity, with different facets — genes, populations, species, deep evolutionary history, ecosystems, and their contributions to people — having markedly different geographic distributions and responses to human drivers. Second, interlinkages among these facets mean that goals must be defined and developed holistically rather than in isolation, with potential to advance multiple goals simultaneously and minimize trade-offs between them. Third, only the highest level of ambition in setting each goal, and implementing all goals in an integrated manner, will give a realistic chance of stopping — and beginning to reverse — biodiversity loss by 2050.

Each cell shows a potential goal (in bold) at a particular level of ambition in attaining it, and some consequences of reaching it, including effects on the other facets of nature and NCP. Only the scenario in green would contribute substantially to “bending the curve” of biodiversity loss. See supplementary materials for further details

Nature: Global priority areas for ecosystem restoration

Extensive ecosystem restoration is increasingly seen as central to conserving biodiversity and stabilising the Earth’s climate. Although ambitious national and global targets have been set, global priority areas accounting for spatial variation in benefits and costs have yet to be identified. Here, for the first time we develop and apply a multicriteria optimisation approach that identifies priority areas for restoration across all biomes and estimates their benefits and costs. We find that restoring 15% of converted lands in priority areas could avoid 60% of expected extinctions, potentially saving 320 thousand species, while sequestering 299 GtCO2, or 30% of total CO2 increase in the atmosphere since the industrial revolution. Including multiple biomes is key to achieving multiple benefits, and cost-effectiveness can increase up to sevenfold with optimised multicriteria spatial allocations. Our results confirm the vast potential contributions of restoration to global challenges while underscoring the necessity of pursuing these goals synergistically.   Link to the article

Nature: Area-based conservation in the twenty-first century

Humanity will soon define a new era for nature—one that seeks to transform decades of underwhelming responses to the global biodiversity crisis. Area-based conservation efforts, which include both protected areas and other effective area-based conservation measures, are likely to extend and diversify. However, persistent shortfalls in ecological representation and management effectiveness diminish the potential role of area-based conservation in stemming biodiversity loss. This study shows how the expansion of protected areas by national governments since 2010 has had limited success in increasing the coverage across different elements of biodiversity (ecoregions, 12,056 threatened species, ‘Key Biodiversity Areas’ and wilderness areas) and ecosystem services (productive fisheries, and carbon services on land and sea). To be more successful after 2020, area-based conservation must contribute more effectively to meeting global biodiversity goals—ranging from preventing extinctions to retaining the most-intact ecosystems—and must better collaborate with the many Indigenous peoples, community groups and private initiatives that are central to the successful conservation of biodiversity. The long-term success of area-based conservation requires parties to the Convention on Biological Diversity to secure adequate financing, plan for climate change and make biodiversity conservation a far stronger part of land, water, and sea management policies.

Associations between socio-environmental factors and landscape-scale biodiversity recovery in naturally regenerating tropical and subtropical forests

Natural regeneration is key for large-scale forest restoration, yet it may lead to different biodiversity outcomes depending on the socio-environmental context. We combined the results of a global meta-analysis to quantify how biodiversity recovery in naturally regenerating forests deviates from biodiversity values in reference to old-growth forests, with structural equation modeling, to identify direct and indirect associations between socioeconomic, biophysical, and ecological factors and deviation in biodiversity recovery at a landscape scale. Low deviation within a landscape means higher chances of multiple sites in naturally regenerating forests successfully recovering biodiversity compared to reference forests. Deviation in biodiversity recovery was directly negatively associated with the percentage of cropland, forest cover, and positively associated with the percentage of urban areas in the surrounding landscape. These three factors mediated the indirect associations with rural population size, recent gross deforestation, time since natural regeneration started, mean annual temperature, mean annual water deficit, road density, land opportunity cost, percentage cover of strictly protected forest areas, and human population variation in the surrounding landscape. We suggest that natural forest restoration should be prioritized in landscapes with both low socioeconomic pressures on land-use conversion to pasturelands and urban areas and a high percentage of forest cover. Direct and indirect associations between socio-environmental factors and deviation in biodiversity recovery. Colored panels indicate different pathways (blue–percentage of forest cover (Forest); purple–percentage of urban areas (Urban); pink–percentage of cropland (Cropland), with solid (direct paths) and dotted lines (indirect paths). Blue lines represent positive associations and red lines, negative associations. Def = gross deforestation rate, Rpop = rural population density, Pop = human population variation, Oppt = land opportunity cost, Road = road density, Time = time since natural regeneration started, WD = water deficit, Temp = mean annual temperature, SPA = strictly protected forest areas. Estimates and standard deviation (in parentheses) are given for each path. R2 values showed independent variables symbols represent the fraction of deviation in biodiversity recovery explained by four multiple generalized linear regressions included in the Structural Equation Model

Bending the curve of terrestrial biodiversity needs an integrated strategy

Bending the curve of terrestrial biodiversity needs an integrated strategy

Plant and animal species across the world are steadily disappearing due to human activity. Without ambitious, integrated action combining conservation and restoration efforts with a transformation of the food system, turning the tide of biodiversity by 2050 or earlier will not be possible. Biodiversity  has been declining at an alarming rate for many years. It is clear that we cannot allow the current trend to continue. If it does, there will simply not be enough nature left to support future generations. While ambitious targets have been proposed, practical issues such as feeding the Earth’s growing human population could make reaching such targets a challenge. The study, which has been published in Nature and forms part of the latest World Wide Fund for Nature (WWF) Living Planet Report, for the first time set out to explore biodiversity targets as ambitious as a reversal in global biodiversity trends and shed light on what integrated future pathways to achieving this goal might entail. According to Bernardo Strassburg, IIS Executive director, Professor of Sustainability Science at PUC-Rio and one of the co-author of the study,  there are major challenges to make the future more sustainable but without a doubt, are worth it. “We have demonstrated that it is possible to combine agricultural production growth with nature conservation and regeneration, and its vital systems, including to the human life. This requires a fully feasible combination of optimized conservation and restoration efforts with reduced food waste, sustainable intensification of production, less impacting diets and more sustainable international trade. It requires political will and the mobilization of consumers and producers, but the rewards would be enormous: by reversing the age-old process of degradation of nature, we would be the first human generation to leave the planet more sustainable than we found it, with enormous benefits for us and for the future generations”, says Strassburg. “If we move away from burning and deforestation and the inevitable loss of value and markets, Brazil has a proven potential to lead this global transition, adding value to agribusiness by positioning itself as the cleanest producer on the planet”. Using multiple models and newly developed scenarios to explore how addressing these elements in an integrated way might help reach biodiversity targets, the study provides key information on pathways that could materialize the 2050 vision of the UN Convention on Biological Diversity – “Living in harmony with nature”. For global trends of terrestrial biodiversity as affected by land use change to stop declining and start recovering by 2050 or earlier, the researchers say that action is needed in two key areas: Bold conservation and restoration efforts together with increased management effectiveness, will have to rapidly be stepped up. The study assumes that protected areas quickly reach 40% of global terrestrial areas. This should happen in tandem with large efforts to restore degraded land (reaching about 8% of terrestrial areas by 2050 in the study scenarios) and land use planning efforts that balance production and conservation objectives on all managed land. Without such efforts, declines in biodiversity may only be slowed down rather than halted and any potential recovery would remain slow. Food system transformation: As bold conservation and restoration efforts alone will likely be insufficient, additional measures are needed to address global pressures on the food system. Efforts to bend the curve of global terrestrial biodiversity include reduced food waste, diets that have a lower environmental impact, and further sustainable intensification and trade. Integrated action would however need to be taken in both areas simultaneously to bend the biodiversity loss curve upward by 2050 or earlier. Conversely, scenarios that combined increased conservation and restoration efforts with efforts to transform the food system showed that opportunities for ambitious conservation and restoration efforts were larger, and potential adverse food security impacts defused, thereby securing a bending of global trends in global terrestrial biodiversity as affected by land use change by 2050. Finally, such transformative change in food and land use systems would also deliver significant co-benefits such as a large contribution to ambitious climate mitigation targets, reduced pressure on water resources, reduced excess of reactive nitrogen in the environment, and health benefits.

Economic Benefits of Protecting 30% of Planet’s Land and Ocean Outweigh the Costs at Least 5-to-1

Economic Benefits of Protecting 30% of Planet’s Land and Ocean Outweigh the Costs at Least 5-to-1

In the most comprehensive report to date on the economic implications of protecting nature, over 100 economists and scientists find that the global economy would benefit from the establishment of far more protected areas on land and at sea than exist today. The report considers various scenarios of protecting at least 30% of the world’s land and ocean to find that the benefits outweigh the costs by a ratio of at least 5-to-1. The report offers new evidence that the nature conservation sector drives economic growth, delivers key non-monetary benefits and is a net contributor to a resilient global economy. The findings follow growing scientific evidence that at least 30% of the planet’s land and ocean must be protected to address the alarming collapse of the natural world, which now threatens up to one million species with extinction. With such clear economic and scientific data, momentum continues to build for a landmark global agreement that would include the 30% protection target. The United Nations Convention on Biological Diversity has included this 30% protected area goal in its draft 10-year strategy, which is expected to be finalized and approved by the Convention’s 196 parties next year in Kunming, China. This new independent report, “Protecting 30% of the planet for nature: costs, benefits and economic implications,” is the first ever analysis of protected area impacts across multiple economic sectors, including agriculture, fisheries, and forestry in addition to the nature conservation sector. The report measures the financial impacts of protected areas on the global economy and non-monetary benefits like ecosystem services, including climate change mitigation, flood protection, clean water provision and soil conservation. Across all measures, the experts find that the benefits are greater when more nature is protected as opposed to maintaining the status quo. Currently, roughly 15% of the world’s land and 7% of the ocean has some degree of protection. The report finds that the additional protections would lead to an average of $250 billion in increased economic output annually and an average of $350 billion in improved ecosystem services annually compared with the status quo. The nature conservation sector has been one of the fastest growing sectors in recent years and, according to the report, is projected to grow 4-6% per year compared to less than 1% for agriculture, fisheries, and forestry, after the world recovers from the COVID-19 pandemic. Protecting natural areas also provides significant mental and physical health benefits and reduces the risk of new zoonotic disease outbreaks such as COVID-19, a value that has not yet been quantified despite the extraordinarily high economic costs of the pandemic. A recent study estimated the economic value of protected areas based on the improved mental health of visitors to be $6 trillion annually. “Our report shows that protection in today’s economy brings in more revenue than the alternatives and likely adds revenue to agriculture and forestry, while helping prevent climate change, water crises, biodiversity loss and disease. Increasing nature protection is sound policy for governments juggling multiple interests. You cannot put a price tag on nature — but the economic numbers point to its protection,” said Anthony Waldron, the lead author of the report and researcher focused on conservation finance, global species loss and sustainable agriculture. The report’s authors find that obtaining the substantial benefits of protecting 30% of the planet’s land and ocean, requires an average annual investment of roughly $140 billion by 2030. The world currently invests just over $24 billion per year in protected areas. “This investment pales in comparison to the economic benefits that additional protected areas would deliver and to the far larger financial support currently given to other sectors,” said Enric Sala, co-author of this report, explorer-in-residence at the National Geographic Society and the author of the forthcoming book The Nature of Nature: Why We Need the Wild (August 2020). “Investing to protect nature would represent less than one-third of the amount that governments spend on subsidies to activities that destroy nature. It would represent 0.16% of global GDP and require less investment than the world spends on video games every year.” According to Dr. Bernardo B. N. Strassburg, CSRio Coordinator and Professor of the Department of Geography and the Environment, Pontifical Catholic University of Rio de Janeiro and Executive Director of International Institute for Sustainability, “The report is a very robust addition to a growing body of evidence that conserving and restoring nature is a sound investment decision. In addition to benefitting society as a whole, the report crucially demonstrates that conserving nature pays off even for sectors such as agriculture. This underscores that nature conservation should be at the heart of societies’ economic plans for recovering from the Covid crisis and can foster development over the coming decades.” The Campaign for Nature (CFN), which commissioned this report, is working with a growing coalition of over 100 conservation organizations, and scientists around the world in support of the 30%+ target, and increased financial support for conservation. CFN is also working with Indigenous leaders to ensure full respect for Indigenous rights and free, prior, and informed consent. CFN recommends that funding comes from all sources, including official development assistance, governments’ domestic budgets, climate financing directed to nature-based solutions, philanthropies, corporations, and new sources of revenue or savings through regulatory and subsidy changes. As 70-90% of the cost would be focused on low and middle income countries because of the location of the world’s most threatened biodiversity, these countries will require financial assistance from multiple sources.

The Review of Biomass Potential for Agricultural Biogas Production in Poland

The Review of Biomass Potential for Agricultural Biogas Production in Poland

Adequate management of biomass residues generated by agricultural and food industry can reduce their negative impacts on the environment. The alternative use for agricultural waste is production of biogas. Biomass feedstock intended as a substrate for the agricultural biogas plants may include energy crops, bio-waste, products of animal and plant origin and organic residues from food production. This study reviews the potential of selected biomass residues from the agri-food industry in terms of use for agricultural biogas production in Poland. The most common agri-food residues used as substrates for biogas plants in Poland are maize silage, slurry, and distillery waste. It is important that the input for the agricultural biogas installations can be based on local wastes and co-products that require appropriate disposal or storage conditions and might be burdensome for the environment. The study also discusses several limitations that might have an unfavourable impact regarding biogas plants development in Poland. Given the estimated biomass potential, the assumptions defining the scope of use of agricultural biogas and the undeniable benefits provided by biogas production, agricultural biogas plants should be considered as a promising branch of sustainable electricity and thermal energy production in Poland, especially in rural areas.

Games and the Communication of Ecosystem Services to Non-Scientific Audiences

Games and the Communication of Ecosystem Services to Non-Scientific Audiences

Scientific results should also be disseminated to non-scientific audience. Communication and knowledge exchange are, generally, not treated as priority for scientists possibly due to lack of time, interest or reward. We conducted an environmental education activity through an active learning method in a high school of Rio de Janeiro, which aim to explain activity concepts of environmental resources management, tragedy of commons, tipping point and reproduction rate. The game was focused on fisheries, but similar concepts are used in the management of other commons such as water, air, and increasingly soils. The activity and the results are presented in a short video:

Biochar amendment improves degraded pasturelands in Brazil: environmental and cost-benefit analysis

Biochar amendment improves degraded pasturelands in Brazil: environmental and cost-benefit analysis

Most deforested lands in Brazil are occupied by low-productivity cattle ranching. Biochar has been shown to improve soil properties and agricultural productivity when added to degraded soils, but these effects are context-dependent. The impact of biochar, fertilizer and inoculant on the productivity of forage grasses in Brazil (Brachiaria spp. and Panicum spp.) was investigated from environmental and socio-economic perspectives. We showed a 27% average increase in Brachiaria production over two years but no significant effects of amendment on Panicum yield. Biochar addition also increased the contents of macronutrients, soil pH and CEC. Each hectare amended with biochar saved 91 tonnes of CO2eq through land sparing effect, 13 tonnes of CO2eq sequestered in the soil, equating to U$455 in carbon payments. Biochar could improve productivity of degraded pasturelands in Brazil if investments in efficient biochar production techniques are used and biochar is subsidized by low emission incentive schemes. Watch below videos about on-farm biochar production and its practical applications in Brazil:

Global restoration opportunities in tropical rainforest landscapes

Global restoration opportunities in tropical rainforest landscapes

Over 140 Mha of restoration commitments have been pledged across the global tropics, yet guidance is needed to identify those landscapes where implementation is likely to provide the greatest potential benefits and cost-effective outcomes. By overlaying seven recent, peer-reviewed spatial datasets as proxies for socioenvironmental benefits and feasibility of restoration, we identified restoration opportunities  in lowland tropical rainforest landscapes. We found restoration opportunities throughout the tropics. Areas scoring in the top 10% are located largely within conservation hotspots (88%) and in countries committed to the Bonn Challenge (73%), a global effort to restore 350 Mha by 2030. However, restoration hotspots represented only a small portion (19.1%) of the Key Biodiversity Area network. Concentrating restoration investments in landscapes with high benefits and feasibility would maximize the potential to mitigate anthropogenic impacts and improve human well-being.
