Pisando na terra invisível: sobre a importância de comunicar o valor dos solos

Para entendermos melhor a percepção do solo pelas pessoas, realizamos entrevistas e dinâmicas na Polônia e no Brasil. Descobrimos que grande parte dos entrevistados o associa à superfície onde as plantas crescem e a alguns serviços ecossistêmicos específicos. A maioria disse precisar aumentar o entendimento sobre a importância do recurso e ressaltou a necessidade de um maior engajamento dos jovens. Tendo este resultado como ponto de partida e buscando ampliar o conhecimento sobre os benefícios do solo a partir de uma abordagem interessante e inovadora, desenvolvemos uma música, dois curtas-metragens documentais e duas oficinas artísticas. Além da finalidade de divulgação científica, as últimas iniciativas ainda foram utilizadas para coletar dados sobre a percepção do solo. Esta é uma nova abordagem para envolver partes interessadas relevantes e promover uma gestão de recursos mais sustentável. Assista aos documentários, ouça a música e aprecie os resultados das pinturas: Com uma proposta interessante e inovadora de coleta e disseminação de informações científicas, o vídeo apresenta depoimentos de moradores locais, turistas e cientistas visitantes sobre suas percepções do solo e sua relação pessoal com o recurso em quatro diferentes ecossistemas do estado do Rio de Janeiro. Unindo a ciência às artes, o vídeo retrata duas atividades artísticas realizadas com materiais do solo por dois grupos diferentes: cientistas e profissionais da saúde na linha de frente do combate ao COVID-19. Nele é explicado como as oficinas foram concebidas e conduzidas, assim como o solo e outros elementos naturais foram coletados e preparados. Além disso, foram registrados os depoimentos dos participantes sobre o que buscaram representar nas suas pinturas e quais significados atribuíram ao solo. Por fim, é apresentada uma música buscando chamar a atenção sobre a importância do recurso. As pinturas também serão usadas para exposições em universidades, jardins botânicos, escolas e instituições de pesquisa relacionadas à educação voltada para o solo no Rio de Janeiro.Related: manifesto cccp significato, ankh found in south africa, what nationality is judge john schlesinger, sweet revenge novel sylvia and simon by nuit, atlantic starr member dies, brian sullivan obituary, stephen cooper obituary, the retreat liverpool, ny lunch menu, is the medical center area in houston safe, who is the killer in i love you ara, miller wedding hashtags, harley street psychologist, obituary 2020 death, john jay financial aid disbursement dates, medicine hat emergency wait times,Related: chicken leek and mushroom pie maggie beer, nick riewoldt wife cancer, donna grant lauren graham, how do you get 9999 enchantments in minecraft, industry risk premium by sic code, my dad never says he’s proud of me, abc 7 sarasota news anchors, steven spielberg maine house, distancia de siembra de la guayaba, dog limping 1 year after tplo surgery, leon hart net worth, does non alcoholic beer make you bloated, why did john marshall jones leave in the cut, north woods law rabid bobcat, painter wanted craigslist,Related: mobile homes for sale berkeley springs, wv, will and tessa balcony scene, osmotic pressure of urea, sister rosamund lupton ending explained, identogo nj service code, judge jaclyn medina bergen county, sealed bearings vs greasable bearings, sailormen talentreef applicant portal, why do armenians drive nice cars, who is jett williams married to, inhaled mold dust from lemons, how to hatch a carbonemys egg in ark, game of life rockstar edition rules, placer county court case search, what does pork mean in marines,Related: christian dior executive team, uva fraternity rush 2020, narda comedor chocolate cake recipe, does alec cabacungan have teeth, 2016 honda civic 12v power outlet, supercross champions by year, parkway high school famous alumni, new homes for sale in weeki wachee, fl, championship rugby player salary, the man who did not smile yasunari kawabata, stipendio netto ricercatore tipo b, cheryl mcadams flight attendant real, lane county election candidates 2022, uscis preparer’s contact information, certification, and signature form, roller skating in bend oregon,Related: short professional teacher bio examples, jesse lingard mother and father, sims 4 faster university mod, michigan utility easement law, kent state athletic department salaries, jeff wittek injury photos, simulate chicken nuggets, does anthropologie restock sold out items, genesis women’s shelter donation drop off, pssa job in royal adelaide hospital, aceite de coco en el ombligo para adelgazar, cuisinart coffee maker error code eeo, richfield ut police scanner, funniest obituaries ever written, is lamium toxic to dogs,Related: charcuterie board delivery california, corpus christi parish priest, el komander wife, mci shirley famous inmates, how old was richard egan when he died, what does it mean to complete tinder, coors field diaper bag policy, signification trompette dans la bible, la quinta california real estate, no communication with pcm, country club of sapphire valley initiation fee, spin the wheel football teams champions league, functionalist perspective on human trafficking, norfolk, ne arrests and citations, basketball or nothing: where are they now,Related: jeffrey gunter ambassador, john michael cree denton county, sally boyd rafael campos, jason white lubbock, liverpool fans convicted heysel names, arizona wildcats softball roster, sophisticated backpacks for fabric, what happened to bruno hauptmann’s son, sherri and terri funeral, wakefield express obituaries page, dogeminer 2 hacked save, example of manpower requirements in business plan, ed gein house location, fraser river pollution, clione limacina for sale,

Economic Analysis of Biochar Use in Soybean Production in Poland

Economic Analysis of Biochar Use in Soybean Production in Poland

Soybean (Glycine max L.) is one of the most important crops grown globally. Biochar has been proposed as an alternative to aid sustainable soybean production. However, comprehensive studies that include both the economic aspects of soybean production and biochar are scarce. Poland, with an economy largely based on agriculture, is an interesting case to investigate the cost-effectiveness of using biochar in soybean production. This study shows that the use of biochar at rates of 40, 60 and 80 t/ha is unprofitable compared with a traditional soil amendment, such as NPK fertilization. The breakeven price for biochar to be economically viable should be USD 39.22, USD 38.29 and USD 23.53 for 40, 60 and 80 Mg/ha biochar, respectively, while the cost of biochar used for this experiment was USD 85.33. The payback period for doses of 40 and 60 Mg/ha was estimated to be three years. With a carbon sequestration subsidy of USD 30 per ton of CO2, the use of biochar may be profitable in the first year of soybean production. This is the first comprehensive economic analysis of the use of biochar in soybean production in Poland and one of the few published worldwide. Efficiency of using biochar (in tonnes of soybean per hectare, Y axe) from sunflower husk (BA) and wood chips (BB). Axe X indicates doses of biochar used in the experiment. Wilks Lambda = 0.67323, F (12, 606.17) = 8, 1485, p = 0.00000.

Socioeconomic impacts of urban restoration in the Atlantic Forest, Brazil

Socioeconomic impacts of urban restoration in the Atlantic Forest, Brazil

Ecological restoration provides a range of ecosystem services. However, the social aspects of restoration are rarely reported. This study assesses the socioeconomic effects of the restoration project called “Mutirão Reflorestamento” (MR), located in an urban fragment of Atlantic Forest in Rio de Janeiro. It was conducted a survey in eight communities, involving 139 residents, where 62 worked for the MR Project, and 77 were not directly involved. Data was collected from focus groups (N = 23, totalling 62 participants) and personal interviews (N = 44). They found out that the main positive contributions of the MR Project were job creation and increased income. The presence of Forest was also associated with the improvement of air and life quality, for example through the provision of recreational areas. The lack of formal work benefits and recently reduced budget for the project were indicated as negative aspects of the MR Project. The main recommendations to improve the Project were: enhance communication between city hall, residents and MR participants, and the appraisal and recognition of the project participants. The results represent the voices of communities directly involved and impacted by restoration, and they may contribute to improving restoration projects in tropical countries. Ranking of the participants’ perceptions (project participants – PP and non-project participants – NPP) about “What the forest means to you?” (number of PP = 64 and NPP = 35).

Areas of global importance for conserving terrestrial biodiversity, carbon and water

Areas of global importance for conserving terrestrial biodiversity, carbon and water

To meet the ambitious objectives of biodiversity and climate conventions, the international community requires clarity on how these objectives can be operationalized spatially and how multiple targets can be pursued concurrently. To support goal setting and the implementation of international strategies and action plans, spatial guidance is needed to identify which land areas have the potential to generate the greatest synergies between conserving biodiversity and nature’s contributions to people. Bernardo Strassburg, CSRio coordinator, is coauthor of a paper published in Nature Ecology & Evolution journal  that presents results from a joint optimization that minimizes the number of threatened species, maximizes carbon retention and water quality regulation, and ranks terrestrial conservation priorities globally. They found that selecting the top-ranked 30% and 50% of terrestrial land area would conserve respectively 60.7% and 85.3% of the estimated total carbon stock and 66% and 89.8% of all clean water, in addition to meeting conservation targets for 57.9% and 79% of all species considered. The data and prioritization further suggest that adequately conserving all species considered (vertebrates and plants) would require giving conservation attention to ~70% of the terrestrial land surface. If priority was given to biodiversity only, managing 30% of optimally located land area for conservation may be sufficient to meet conservation targets for 81.3% of the terrestrial plant and vertebrate species considered. The results provide a global assessment of where land could be optimally managed for conservation. Finally, they discuss how such a spatial prioritization framework can support the implementation of the biodiversity and climate conventions.

Early Response of Soil Properties under Different Restoration Strategies in Tropical Hotspot

Early Response of Soil Properties under Different Restoration Strategies in Tropical Hotspot

The Brazilian Atlantic Forest has undergone adverse land-use change due to deforestation for urbanization and agriculture. Numerous restoration initiatives have been taken to restore its ecosystem services. Deforested areas have been restored through active intervention or natural regeneration. Understanding the impact of those different reforestation approaches on soil quality should provide important scientific and practical conclusions on increasing forest cover in the Brazilian Atlantic Forest biome. However, studies evaluating active planting versus natural regeneration in terms of soil recovery are scarce. This study evaluates soil dynamics under those two contrasting strategies at an early stage (<10 years). Reforestation was conducted simultaneously on degraded lands previously used for cattle grazing and compared to an abandoned pasture as a reference system. It was examined soil physicochemical properties such as: pH, soil organic matter content, soil moisture, N, P, K, Ca, Mg, Na, Fe, Mn, Cu, Al, and soil texture, and presented the costs of both methods. It was found significant differences in restored areas regarding pH, Na, Fe, Mn content, and the cost. Soil moisture was significantly higher in pasture. This research can contribute to better decision-making about which restoration strategy to adopt to maximize restoration success regarding soil quality and ecosystem services in the tropics.

More effort is needed to implement and disseminate soil protection measures for tropical soils

More effort is needed to implement and disseminate soil protection measures for tropical soils

A soil-centric approach is required to protect soils, to enable these soils to deliver their SES at edaphic maxima and thus support wider above and below-ground ecosystems. To protect Brazil’s wider natural capital, and that of other tropical countries, soil protection measures, such as the incorporation of SES in decision-making needs to be explicitly considered in environmental policy and laws. Combining a SES approach with monetary and non-monetary valuation, and subsequently communicating it using a strategic plan, this paper proposes corridors of understanding about the value of soil and importance of adequate land management for biodiversity and goods provision for local and global population. Through such an approach, a range of stakeholders can be reached and mobilised to encourage sustainability of soil stewardship and to elevate appropriate management of soil resource on decision-makers’ agenda.

Payment for water-ecosystem services monitoring in Brazil

Payment for water-ecosystem services monitoring in Brazil

The reduction of tropical forests has generated a loss of ecosystem services across the globe. In Brazil, essential biomes related to water provision (such as the Atlantic Forest and Savanna) have been degraded, compromising water-ecosystem services. Payment for water- ecosystem services (water PES) has been implemented as a tool to stimulate changes in the use and management of these areas. Many water PES projects have emerged in Brazil using forest restoration, aiming to improve water ecosystem services. In this context, this study identified the types of monitoring carried out in Brazilian water PES projects, to include their main characteristics and gaps. Five Brazilian projects were selected for analysis as case studies. Interviews were then conducted with stakeholders to get current data on their monitoring practices. The data from the literature review, case study approach, and interviews were analyzed from the perspective of monitoring guides recommendations. Different aspects were analyzed, such as objectives, institutional arrangements, type of monitoring, indicators, and frequency of monitoring. The study indicates that there is a lack of standardized methods, making it difficult to specify the results of the implemented actions. The central gap is related to benefit monitoring. It is necessary to establish a holistic monitoring system, dealing with the ecosystem as a complex socio-ecological system. Some perspectives to solve the problems were proposed. The results of this work may help not only improve the current and future PES schemes in Brazil but also in other countries, especially developing ones, where vulnerable populations depend upon them.

Soil ecosystem services in tropical regions: a systematic review

Soil ecosystem services in tropical regions: a systematic review

Soil ecosystem service (SES) approaches evidence the importance of soil for human well-being, contribute to improving dialogue between science and decision-making and encourage the translation of scientific results into public policies. In this study, through systematic review, the researchers assess the state of the art of SES approaches in tropical regions. Through this review, 41 publications were identified; while most of these studies considered SES, a lack of a consistent framework to define SES was apparent. Most studies measured soil natural capital and processes, while only three studies undertook monetary valuation. Although the number of publications increased (from 1 to 41), between 2001 and 2019, the total number of publications for tropical regions is still small. Countries with the largest number of publications were Brazil (n = 8), Colombia (n = 6) and Mexico (n = 4). This observation emphasizes an important knowledge gap pertaining to SES approaches and their link to tropical regions. With global momentum behind SES approaches, there is an opportunity to integrate SES approaches into policy and practice in tropical regions. The use of SES evaluation tools in tropical regions could transform how land use decisions are informed, mitigating soil degradation and protecting the ecosystems that soil underpins.

Soil dynamics in forest restoration: a data set for temperate and tropical regions

Soil dynamics in forest restoration: a data set for temperate and tropical regions

Restoring forest ecosystems has become a global priority. Yet, soil dynamics are still poorlyassessed among restoration studies and there is a lack of knowledge on how soil is affected by forestrestoration process. The study compiles information on soil dynamics in forest restoration based on soil phys-ical, chemical, and biological attributes in temperate and tropical forest regions. It encompasses 50 scien-tific papers across 17 different countries and contains 1,469 points of quantitative information of soilattributes between reference (e.g., old-growth forest) and restored ecosystems (e.g., forests in their initial orsecondary stage of succession) within the same study. To be selected, studies had to be conducted in forestecosystems, to include multiple sampling sites (replicates) in both restored and reference ecosystems, andto encompass quantitative data of soil attributes for both reference and restored ecosystems. We recordedin each study the following information: (1) study year, (2) country, (3) forest region (tropical or temper-ate), (4) latitude, (5) longitude, (6) soil class, (7) past disturbance, (8) restoration strategy (active or pas-sive), (9) restoration age, (10) soil attribute type (physical, chemical, or biological); (11) soil attribute, (12)soil attribute unit, (13) soil sampling (procedures), (14) date of sampling, (15) soil depth sampled, (16) soilanalysis, (17) quantitative values of soil attributes for both restored and reference ecosystems, (18) type ofvariation (standard error of deviation) for both restored and reference ecosystems, and (19) quantitativevalues of the variation for both restored and reference ecosystems. These were the most common dataavailable in the selected studies. This extensive database on the extent soil physical, chemical, and biologicalattributes differ between reference and restored ecosystems can fill part of the existing gap on both soilscience and forest restoration in terms of (1) which are the critical soil attributes to be monitored duringforest restoration? and (2) how do environmental factors affect soil attributes in forest restoration? Thedata will be made available to the scientific community for further analyses on both soil science and forestrestoration. Soil information gaps during the forest restoration process and their general patterns can beaddressed using this data set. There are no copyright or proprietary restrictions.

Survey-based qualitative analysis of young generation perception of sustainable development in Poland

Survey-based qualitative analysis of young generation perception of sustainable development in Poland

Understanding the perception of Sustainable Development can help to identify misconceptions surrounding the concept in order to design better education plans and public policies on this subject. Evaluating the perception of sustainability issues by focusing on the young generation as is an important proxy to imagine what the future holds for in terms of addressing sustainable development. We conducted 177 in-person interviews on a heterogeneous group of students and random volunteers in four cities in Poland to assess their perception of Sustainable Development. The vast majority (89.3%) of the respondents were familiar with the term ‘Sustainable Development’. However, part of them (57%) associated it only to the human and social development dimensions and its institutions, whereas 17.5% related it with its environmental aspects. The results supported by the literature review highlight challenges concerning the path towards a comprehensive perception of Sustainable Development and hence the achievement of the SDGs. Based on these results, we identify opportunities and incentives to bring Poland towards 2030 Agenda.
