Marshaling science to advance large landscape conservation

AbstractApplying science to conservation requires deliberate planning and action infrequently taught in academic settings. To illustrate impactful analysis and science communication, we describe scientific activities targeting the needs of land trusts, NGOs, landowners, and government agencies working to conserve the Florida Wildlife Corridor (“Corridor”). This 7.2 million hectare area is prioritized for habitat connectivity conservation in the US state of Florida. Our activities are built on decades of science guiding Florida land conservation. We quantified threats (e.g., average of over 14,000 ha of development/year from 2001 to 2019) and socio‐ecological benefits of Corridor conservation, prioritized yet‐to‐be‐conserved Corridor areas, produced and shared a new statewide connectivity model, and convened groups to identify campaign science needs. The new connectivity model—the Florida Circuit Model—supported the geography of the Corridor, as designated, and facilitates local (10 km radius, or less) conservation planning. Our efforts have contributed to allocation of over $2 billion for land conservation and the permanent protection of over 82,000 ha within the Corridor by state agencies from June 2021 to March 2024. Targeting science to outreach and policy, planning, and management decisions can motivate public, media, researcher, and government support for land conservation, improve conservation interventions, and attract research funding.

Effects of fluid salinity and composition on subcritical crack growth in marble

Subcritical fracture growth of rocks in fluid-chemical environments played a crucial role in the weathering process of rocks and the preservation of stone building heritage. Fracture mechanics properties of marble under different fluid compositions and salinity conditions were investigated by carrying out double torsion tests. The subcritical crack growth index (SCI) exhibited different salinity dependencies in two salt solutions. In NaCl solution, the SCI decreased by 1.97 % – 40.50 % with increasing salinity due to the increase in solubility of calcite. The SCI decreased by 4.60 % and 14.01 % respectively as the Na2SO4 salinity increases from 0.01 mol/L to 1 mol/L, and then increased with the increase in salinity, which was related to the relationship between calcite solubility and salinity. Compared to Na2SO4 solution, the weakening effect of NaCl solution on Ka was smaller. In contrast, the fracture toughness (KIC) was insensitive to fluid composition and salinity in the short term, with KIC ranging from 0.65 to 0.79 MPa m1/2 in all salt solutions. The three-dimensional morphology results of the fracture surfaces indicated that the effect of salinity on the roughness of both fracture types was negligible. However, the microstructure of the marble was significantly affected by salinity, and apparent dissolution was observed. The results highlighted the dependence of the subcritical fracture behavior of marble on fluid chemistry, which had implications for the weathering assessment of stone masonry buildings and the permanent protection of stone heritage monuments. In these applications, fluid chemistry could either strengthen or weaken the rock, depending on variations in fluid composition and salinity.

Multicriteria Model for Prospective Locations for Sediment Dump Sites Coastal Dunes Management: Case Study from Barroquinha City, Northeast Brazil

Coastal zones are attractive for the development of economic interests (real estate and tourism) and are intensely occupied in a disorderly manner. Development in areas with available sediments can lead to conflicts between the natural movement of dunes and cities and communities and may result in burial processes. In addition, natural structures, such as dunes, play key roles in protecting against coastal erosion by balancing the beach-dune system with the sediment input, thus slowing the erosion process. This study aims to determine suitable areas for creating dune field dump sites in Barroquinha, Ceará, northeastern Brazil. The results showed that along the study area, the places with the greatest viability for creating dump sites were those furthest from the urban and permanent protection areas. In the stretch connecting Barroquinha City to the Bitupitá community on the CE-187 highway, 45 deposition points were monitored across five sectors under different environmental conditions. Sectors 2, 3, and 4 showed good responses to sediment fixation, in agreement with what was presented in the locational feasibility model. These results add to the discussion on urban infrastructure burying processes, making important contributions to urban planning and management in coastal areas. The results of this study will form an integral part of the Regional Contingency Plan for Incidents and/or situations of risk of environmental impacts in the coastal and/or oceanic zones of Ceará, which was conceived by the Chief Environment Scientist Program of Ceará State and contributes to the Action Plan against burying infrastructure by dune fields.

Seroja Tropical Cyclon Destruction Case Study: Permanent Slope Protection Evaluation at Downstream of Rotiklot Dam Nomenclature Building, East Nusa Tenggara, Indonesia

Abstract Rotiklot Dam was one of some infrastructures which was affected by the Seroja Tropical Cyclone in East Nusa Tenggara Indonesia in April 2021. There are several landslides at the downstream of the dam that can threaten the safety of the dam, especially at the downstream of the nomenclature building. The right design of permanent slope protection must be determined in a limited time. Geotechnical investigations such as boring, resistivity survey, standard penetration test, and water pressure test were conducted in a short time. Back analysis method was carried out to find extreme soil parameters conditions. The slope protection must meet the national standard minimum safety factor or greater than 1.5. Safety factors of slope protections are evaluated by a finite element method to get the safety factor and maximum total displacements. Every stage of slope protection can give the optimal safety factor values which are required or greater than 1.5, however backfill material will give more load and decrease the safety factor value.

Challenges for reducing carbon emissions from Land-Use and Land Cover Change in Brazil

Brazil, a crucial player in global climate change mitigation, faces challenges in reducing its carbon emissions, of which nearly half are from land use changes. Despite potential reductions that can be achieved through halting deforestation and fostering forest restoration, setbacks in environmental governance have heightened emissions. This article assesses challenges and proposes solutions for conserving and restoring Brazilian biomes in line with the Sustainable Development Goals (SDGs) and the Paris Agreement by 2030. Notably, net carbon emissions from land-use change and forestry increased twofold from 2017 to 2022 due to deforestation in the Amazon and Cerrado. Native vegetation clearing peaked at 2.8 Mha in 2022, the largest area since 2008. The deficit of native vegetation within Legal Reserves and Permanent Protection Areas must be addressed through restoration. Achieving SDGs by 2030 demands urgent action against illegal deforestation, reinforced legislation for secondary forest protection, large-scale restoration programs, and economic incentives for forest conservation through payment for ecosystem services to rural landowners.

Panel Data Analysis in Identifying and Mapping Caused Factors of Financial Crises and Monetary Instability in Developing Countries

This study aims to reveal the extent of macroeconomic instability, which has the characteristics of a financial crisis and inflation. To test the hypothesis, researchers use fixed effects and random effects estimators to assess the presence of individual and temporal effects. Macroeconomic fundamentals, especially the risk of devaluation and a drop in economic activity can be seen as early warning signs of banks becoming less solvent. They also play a big role in explaining how deposits changed during the crisis. Our findings highlight the unique features of the convertible monetary regime, reinforcing the belief that debtors will enjoy permanent protection against devaluation risks. This perception encourages the dollarization of bank portfolios, thereby increasing the financial system's solvency risks. There is also evidence that the regulatory framework in this area is weak when it comes to the financial system's exposure to devaluation risks and public debt risks. This is especially true when it comes to an institutional framework that makes it hard for government funding to be changed into other currencies. We find that inflation is a very persistent process during periods of high inflation. However, with the decline in inflation after the implementation of the convertibility regime, its persistence reduced significantly. The results show that non-rational persistence is currently not very high, suggesting that the costs of designing the economy should not be either. We find that univariate models tend to perform better over very short horizons. The results suggest that there may be advantages to using a combination of different models, provided they are informative about the relationship between inflation and its short- and long-run determinants.

Clarifying ‘long-term’ for protected areas and other effective area-based conservation measures (OECMs): why only 25 years of ‘intent’ does not qualify

The concept of ‘long-term’ is a key part of the definitions of both protected areas and other effective area-based conservation measures (OECMs). Draft principles for OECMs in Australia developed by the Australian Government propose a minimum period for OECMs of 25 years, where a landholder is not able to commit to in-perpetuity conservation. The proposal suggests this is consistent with IUCN Guidelines for Privately Protected Areas. As authors of the Guidelines for Privately Protected Areas we contend however that Australia’s proposed OECM guideline suggesting 25 years of “intention” to deliver biodiversity outcomes is ‘long-term’ is not supported by IUCN guidelines. Furthermore for protected areas, Australia has a long-established definition of ‘long-term’ – specifically a minimum timeframe of 99 years is required if permanent protection is not possible – embedded in both national policy and legal agreements. As national governments rapidly seek to define OECMs in response to the raised ambitions of the Kunming-Montreal Global Biodiversity Framework, there will be increasing interest in what counts towards Target 3. Ultimately, more land managed for conservation is good and all forms of area-based conservation should be encouraged. However, not all forms of area-based conservation qualify for inclusion in Target 3. Long-term intent and outcomes are fundamental, as outlined in the definitions of protected areas and OECMs.

A spider mating plug functions to protect sperm.

Mating plugs in animals are ubiquitous and are commonly interpreted to be products of mating strategies. In spiders, however, mating plugs may also take on functions beyond female remating prevention. Due to the vagaries of female genital (spermathecal) anatomy, most spiders face the problem of having to secure additional, non-anatomical, protection for transferred sperm. Here, we test the hypothesis that mating plugs, rather than (or in addition to) being adaptations for mating strategies, may serve as sperm protection mechanism. Based on a comparative study on 411 epigyna sampled from 36 families, 187 genera, 330 species of entelegyne spiders, our results confirm the necessity of a sperm protection mechanism. We divided the entelegyne spermathecae into four types: SEG, SED, SCG and SCD. We also studied detailed morphology of epigynal tracts in the spider Diphya wulingensis having the SEG type spermathecae, using 3D-reconstruction based on semi thin histological series section. In this species, we hypothesize that two distinct types of mating plug, the sperm plug and the secretion plug, serve different functions. Morphological details support this: sperm plugs are formed on a modified spermathecal wall by the spilled sperm, and function as a temporary protection mechanism to prevent sperm from leaking and desiccating, while secretion plugs function in postcopulation both as a permanent protection mechanism, and to prevent additional mating. Furthermore, with the modified spermathecal wall of S2 stalk, the problem of shunt of sperm input and output, and the possibility of female multiple mating have been resolved. Variation in spermathecal morphology also suggests that the problem of sperm protection might be resolved in different ways in spiders. Considering mating plugs of varying shapes and origins in the vast morphospace of spiders, we conclude that mating plugs might serve different purposes that relate both to mating strategies, as well as to sperm protection.

Review on Lightweight Mobile Flood Wall Barrier: Way Forward for Malaysia

Flooding is a persisting challenge in Malaysia. Combating flood risk has become a main priority for sustainable development in this country. The application of sophisticated engineering in hard structure approaches and flood control systems are often incongruous to the public. Therefore, there is a need to integrate the soft engineering approaches and the best practises of flood management to mitigate flood risk. There is also a need to integrate the concept of sustainable development into its planning policies towards flood hazard reduction. Mobile flood protection measures are useful as an alternative solution in flood protection and mitigation purposes. Mobile protective systems can be used for temporarily increasing the height of permanent flood protection structures during extreme events and can be utilised as emergency measure against flooding in unprotected low-lying areas. As the available mobile systems differ in the type of material, method of installation and available protection height, a description of their features, and potential application were examined including their respective opportunities and drawbacks. This article presents a review on different types of lightweight mobile flood wall barrier (MFWB) that were implemented to cope with floods in Malaysia with examples of application in other countries such as United Kingdom, Slovakia, and Netherlands. The MFWB products are reviewed and compared to each other according to the types, characteristics, mechanisms, drawbacks and how these measures are integrated into spatial planning. Based on the findings, several suggestions are given on how to improve the flood risk management in flood-prone areas and way forward for Malaysia.

An architecture for COVID-19 analysis and detection using big data, AI, and data architectures.

The COVID-19 epidemic is affecting individuals in many ways and continues to spread all over the world. Vaccines and traditional medical techniques are still being researched. In diagnosis and therapy, biological and digital technology is used to overcome the fear of this disease. Despite recovery in many patients, COVID-19 does not have a definite cure or a vaccine that provides permanent protection for a large number of people. Current methods focus on prevention, monitoring, and management of the spread of the disease. As a result, new technologies for combating COVID-19 are being developed. Though unreliable due to a lack of sufficient COVID-19 datasets, inconsistencies in the datasets availability, non-aggregation of the database because of conflicting data formats, incomplete information, and distortion, they are a step in the right direction. Furthermore, the privacy and confidentiality of people's medical data are only partially ensured. As a result, this research study proposes a novel, cooperative approach that combines big data analytics with relevant Artificial Intelligence (AI) techniques and blockchain to create a system for analyzing and detecting COVID-19 instances. Based on these technologies, the reliability, affordability, and prominence of dealing with the above problems required time. The architecture of the proposed model will analyze different data sources for preliminary diagnosis, detect the affected area, and localize the abnormalities. Furthermore, the blockchain approach supports the decentralization of the central repository so that it is accessible to every stakeholder. The model proposed in this study describes the four-layered architecture. The purpose of the proposed architecture is to utilize the latest technologies to provide a reliable solution during the pandemic; the proposed architecture was sufficient to cover all the current issues, including data security. The layers are unique and individually responsible for handling steps required for data acquisition, storage, analysis, and reporting using blockchain principles in a decentralized P2P network. A systematic review of the technologies to use in the pandemic covers all possible solutions that can cover the issue best and provide a secure solution to the pandemic.

Conservation from the bottom up: A forestry case study

There is currently great interest in increasing the total land area in ‘conservation’ by the year 2030 to stabilize biodiversity and reduce net carbon emissions to combat climate change; however, there remains a lack of clarity on what actually constitutes ‘conservation.’ Land placed into permanent protection from resource utilization falls under the category of land preservation (e.g. National Parks) where land ‘conservation’ can include resource utilization to meet human resource needs. Land ‘preservation’ is an effective means of protecting habitat, but isolation of preserved parcels can limit their effectiveness. The trade-off between land preservation and conservation requires that we consider land use strategies in a global context and as complementary of one another. Most assessments for increasing land conservation are based on vegetative and wildlife inventory, where far fewer assessments are based on soils or belowground accounting. Herein, we present a soil based perspective that could be useful in evaluating the capacity for different land management strategies to meet broader conservation goals, including 30 by 30 and provide a focus on forest management to demonstrate our approach. Our soils-based assessment of different land-use practices suggests that land management practices that cause minimal soil disturbance, generate minimal bare soil, and exhibit a dominance of native species would be effective at achieving meaningful land conservation benefits while continuing to meet human resource needs. Incentivizing conservation oriented land management practices could dramatically accelerate our ability to achieve large scale conservation objectives such as 30 by 30.

Providing permanent protection to refugees in Australia: Real change or window dressing?

This article argues that the recent changes to Australia’s rolling temporary protection regime do not mark a shift away from Australia’s flawed and unjust asylum system for two key reasons. First, the government did not repeal the temporary protection regime nor the fast track process. Secondly, the changes mobilise and perpetuate the inherent hostility of Australia’s asylum seeker policies targeting ‘irregular arrivals’. This article offers a critical analysis of the design and operation of Australia’s asylum system, as well as an examination of the 2023 changes and the political and journalistic discourse surrounding their announcement.

The Revolving Door of Im/Migration: Canadian Refugee Protection and the Production of Migrant Workers

This paper places the seemingly distinct projects of refugee protection and temporary foreign worker programs alongside one another to reveal their interlinked relationship. I argue that despite its seeming humanitarian exceptionality, refugee protection is deeply implicated in the production of both the category and supply of temporary foreign workers for the Canadian economy. I demonstrate that the defining limitations of refugee law in relation to questions of class and economic deprivation are integral to the conceptualization of the category of the migrant worker. I then engage with statistical data to show that patterns of refugee adjudications in Canada have contributed to maintaining the supply of temporary foreign workers. In particular, I show that Canada has consistently rejected refugee claims from key source countries of migrant workers, namely Jamaica and Mexico. By refusing these claims, Canadian refugee protection has constituted Jamaican and Mexican nationals as inappropriate subjects of permanent protection and, subsequently, primed them for incorporation as temporary foreign workers. In effect, Canadian im/migration has operated like a revolving door: pushing some nationalities out of the permanent protection of refugee status while pulling them into the precarious opening of temporary labour migration.

Development of a context-specific knowledge base for Inherently Safer Design (ISD) in confined spaces: A resource for designers and end users

Confined space work is an important activity in various industries and a significant cause of workplace fatalities worldwide. Accidents and fatalities persist despite international standards, regulations, and efforts to improve safety in confined spaces. To address this issue, it is crucial to understand and disseminate knowledge on accident prevention strategies for confined spaces, to raise awareness among safety practitioners, and to harmonize communication between designers and end-users to anticipate OHS risks throughout a structure's lifecycle. Besides, confined spaces are unique and context-dependent, which affects the flexibility of their design and modifications. This paper introduces a Confined Space Permanent Collective Protection (CSPCP) knowledge base as a set of design-oriented principles and sub-principles that can be integrated into confined spaces to protect workers. It incorporates data from legislative and normative safety management frameworks, Inherently Safer Design (ISD) principles, literature-based solutions, expert knowledge, and contextual guidance on 112 CSPCP solutions based on the analysis of 19 case studies. This guidance is finally presented as a relational database, considering input from experts and client-side designers to understand the advantages and limitations of CSPCP for retrofitting confined spaces or designing and manufacturing new ones. Moreover, it provides owners, designers, and safety specialists access through flexible queries to help them balance safety, profitability, and investment.

Review of terrestrial temporarily conserved areas in Canada, the United States, and Mexico.

The establishment of protected areas is a cornerstone of conservation, but permanent protection could be inefficient or even impossible in some situations. We synthesized the literature on temporarily conserved areas (TCAs) across Canada, the United States, and Mexico. We used a comprehensive search string to retrieve peer-reviewed articles published from 2000 to 2021 from the Web of Science. We identified 27 relevant peer-reviewed articles that examined the potential benefits of TCAs in the study area, indicating TCA is a relatively understudied area of research in the peer-reviewed literature. The TCA studies were highly clustered; 77% of studies focused on protecting a single life stage of migratory species and 61% of studies related to temporary conservation of breeding or staging habitats for migratory birds. Ninety-three percent of studies focused on preventing human-driven threats, mainly on public lands of coastal areas, the Great Plains, and the Mississippi Valley in the central United States. Short-term and experimental studies were the dominant study types. TCAs have the potential to complement permanently protected areas and provide protection when permanent protection is difficult. Some included studies examined their conservation value, but the ecological, social, and economic outcomes of TCAs are unclear. More TCA research is needed to determine the role they could play in conservation worldwide. Embracing the concept of TCAs as conservation tool could lead to more comprehensive and consistent reporting of the outcomes of temporary area-based conservation measures. However, a global review and analysis of effectiveness of TCAs will be required if they are to play a formal role in meeting international targets for biodiversity conservation.

Transformations in the world of healthcare work: workers and future challenges.

This article addresses the world of healthcare work, especially in the Brazilian Unified Healthcare System (SUS) in the context of the COVID-19 pandemic in Brazil. This study used data from the following surveys: "Working conditions of health professionals in the context of COVID-19 in Brazil" and "The Invisible health workers: working conditions and mental health in the context of COVID-19 in Brazil". Data analysis proves that the pandemic highlighted existing structural problems within SUS, involving the issue of healthcare workforce (HWF) management, which can be interpreted as another reflection of the socioeconomic inequalities that already exist in the country. This article highlights: the reduced provision of permanent education, the regulation of hybrid care, precariousness, a lack of protection in the work environment, as well as fragile biosecurity leading to tragic rates of illness and death of health workers. Our study concludes by showing the importance of formulating public policies in the scope of education and work management in SUS that ensure the discussion on hybrid care as a new way of acting without losing quality, together with the need to review issues related to permanent education, protection, valuation, and reduction of inequalities pointed out among the professional contingents analyzed in this article.

Breakeven price of CO2 credits driving farmers to use the area to plant forest instead of grain

Afforestation and reforestation were the challenges the farmer can seize to plant a culture that can capture more carbon than the amount emitted for cultivation. Assuming that the land was legally rented and owned, and part of an area that had not been obtained through recent deforestation, the main questions were: “why a farmer should have preferred to reserve the area to plant trees?”; and “How much did one ton of Carbon Dioxide [CO2] have to be rewarded to buy this opportunity?” This work had the target to estimate which was the minimum price for carbon credit so that the farmer will plant a forest instead of using the soil for grain cultivation. Based on the analysis that economic aspects and profit were the main drivers considered by the farmer to decide how to use the soil in case the area was not classified as Legal Reserve or Permanent Protection Area, seeking the usage which maximized the value per hectare. Considering a eucalyptus commercial forest planted under the premises of the current study, results showed that a price of around 24 BRL per ton of CO2 in 2021 is enough to turn it economically feasible. Business case had been estimated with and without profit coming from the commercial use of forest, and even assuming that no wood is cut and sold, the 2021 price of 40,48 BRL per ton of CO2 can ensure more profit than grain production over 14 years timeframe, allowing the farmer to make money beyond the usual commercial use of a forest.

Living in Limbo: The Experiences of People Seeking Asylum in Australia

Over the past two decades, the Australian policy environment has become increasingly focused on deterring asylum seekers. For people who arrived by sea between August 13, 2012 and January 1, 2014 (legally considered the “legacy caseload”), policy measures include border excision, the removal of permanent protection and family reunion, and restrictions on economic and social rights. This research reports the results of 15 In-depth, semi-structured interviews, with legacy caseload asylum seekers to explore how policy instruments affected and governed their lives. This research found that the prolonged refugee determination process excludes people seeking asylum from meaningful support. This research contends people seeking asylum in Australia exist in a liminal space—in a state of exclusion enforced by the government.
