ContextRelationships between land surface temperature (LST) and spatial configuration of urban form described by landscape metrics so far have been investigated with coarse resolution LST imagery within artificially superimposed land divisions. Citywide micro-scale observations are needed to better inform urban design and help mitigate urban heat island effects in warming climates.ObjectivesThe primary objective was to sub-divide an existing high-resolution land cover (LC) map into groups of patches with distinct spatial and thermal properties suitable for urban LST studies relevant to micro-scales. The secondary objective was to provide insights into the optimal analytical unit size to calculate class-level landscape metrics strongly correlated with LST at 2 m spatial resolution.MethodsA two-tiered unsupervised k-means clustering analysis was deployed to derive spatially distinct groups of patches of each major LC class followed by further subdivisions into hottest, coldest and intermediary sub-classes, making use of high resolution class-level landscape metrics strongly correlated with LST.ResultsAggregation class-level landscape metrics were consistently correlated with LST for green and grey LC classes and the optimal search window size for their calculations was 100 m for LST at 2 m resolution. ANOVA indicated that all Tier 1 and most of Tier 2 subdivisions were thermally and spatially different.ConclusionsThe two-tiered k-means clustering approach was successful at depicting subdivisions of major LC classes with distinct spatial configuration and thermal properties, especially at a broader Tier 1 level. Further research into spatial configuration of LC patches with similar spatial but different thermal properties is required.

The role of the refugee crises in driving forest cover change and fragmentation in Teknaf, Bangladesh

The establishment of protected areas (PA) is one of the most prominent biodiversity conservation policies in the Philippines. Functions of the country’s PA policy include the reduction of deforestation, forest conservation, and decreasing human pressure on natural resources. This study aimed to assess the drivers of forest intactness and fragmentation in selected terrestrial PAs. Management Effectiveness Tracking Tool (METT) scores were used to consider the impact of drivers of land use and land cover (LULC) change, including economic development, population, road networks, cultivation, and PA management, on the percentage of forest cover and different fragmentation metrics in the PAs. The study conducted a Canonical Correlation Analysis (CCA) and Multiple Regression Analysis to identify the significant drivers of LULC change for each response variable. CCA and Multiple Regression Analysis results showed the most important predictors of LULC based on their canonical weights: cultivation within the PA, the human development index, and the regional gross domestic product. Aside from being the most important driving factor based on the CCA, cultivation inside the PA was also found to be a common significant variable for most dependent variables. Other significant factors were poverty index, population, and road density, which could all provide a basis for the observed PA fragmentation. The study also found that higher METT scores had a negative influence on the open forest and a positive effect on patch richness. This indicates that open forests tend to decrease as PA management improves while patch richness tends to increase. Furthermore, there is no data to support that METT scores have a significant influence on other response variables.

Land use change due to human activity can have serious, often irreversible effects on the environment. It affects ecosystem functions and the sustainability of protected natural areas. Problems such as fragmentation, low habitat connectivity or a decline in a territory’s ability to capture carbon are some of its consequences. By studying past land use trends we can simulate future land uses, and modeling such trends is essential if a preventive approach to the management of protected areas is to be adopted. The aim of this chapter is to simulate different change scenarios in protected natural areas in the urban region of Madrid, from National and Nature Parks to Special Areas of Conservation and Special Protection Areas. To this end we study land use changes both inside and around these protected areas. CORINE Land Cover maps from 1990, 2000 and 2006 are used. Cross-tabulation techniques are applied in order to study trends in land use change. Three scenarios are designed: a baseline or trend scenario, an economic crisis scenario and a green scenario. The CLUE model (based on logistic regression) is used. LCM (based on neural networks) is also used but only in the trend scenario. Biophysical, socio-economic and accessibility factors and incentives and restrictions are considered. FRAGSTATS and GUIDOS are used to analyse the effect of infrastructure and built-up land growth on connectivity and fragmentation. In recent decades, the region of Madrid has experienced intense urban and infrastructure development (48,332 ha). Protected areas have been affected by this urbanization process. Built-up areas have grown at an average annual rate of 5.52% in protected areas and around them. According to the trend scenario, the built-up area will increase by 28,000 ha over the period 2006–2025 to 7.6% of the study area. No fragmentation processes are expected in the National Park. However, fragmentation of agricultural and natural habitats around protected areas is expected to increase by 7.2% during this period. These findings should alert land use planners and the managers of protected areas to the potential threats.

trialspecies,therelativemeritsofdifferentapproachesto ensure the long-term persistence of those species remain highly contentious. Most would agree, however, that both establishing protected areas and exercising some form of restraint on extraction of forest resources are among the most effective of all viable conservation measures. Deforestation, wildfires, logging, and hunting are among the leading drivers of species losses in tropical forests, and de facto or de jure protection from these threats can be conferred by either effective enforcement of regulations or physical remoteness. Attempts to assess conservation success of protected areasatlargescaleshaverestedprimarilyonconventional use of remote sensing to quantify spatial or temporal differences in rates of change in land cover due to deforestation and wildfires, rather than on empirical demographic or community-level metrics (Gaston et al. 2008). Q2 However, the former approaches fail to detect most types of subcanopy anthropogenic disturbances that also result, directly or indirectly, in species losses (Peres et al. 2006). Moreover, the effects of habitat loss and degradation on population extirpations and declines are nonlinear, so vegetation cover alone is rarely a robust proxy for the viability of terrestrial biotas. Remotesensing data show vast tracts of apparently intact tropical forests, but in reality levels of hunting and other forms of extraction in these areas are often unsustainable (Peres & Lake 2003). Fundamental questions yet to be answered include whether ostensibly intact protected areas retain full complements of forest species and how the extent of cryptic patterns of disturbance is related to human population density in both protected and unprotected areas. I considered the global to regional emergence of sustainable-use reserves, emphasizing the world’s largest tropical forest region, Amazonia. Sustainable-use reserves often have intermediate levels of disturbance, so I examined the degree of use of natural resources by resident communities and used human population density as a proxy for level of extraction. In both protected and unprotected areas, I also estimated responses of game vertebrate assemblages to hunting on the basis of the relative biomassextractedfromasubsetoftheforestfauna.Iused analysesofcovariance(ANCOVA)toexaminetheassociationbetweenhumandensityandgamebiomassharvested across different reserve categories. Finally, I considered the long-term capacity of sustainable-use forest reserves to maintain populations of all resident species.

Assessing deforestation and fragmentation in a tropical moist forest over 68 years; the impact of roads and legal protection in the Cockpit Country, Jamaica

Strengthening research efforts to understand the combined impacts of conservation and livelihoods in protected areas (PAs) will increase the collective contribution that PAs can make towards meeting global goals for sustainable development in the next decade. As an example of such efforts, in 2014 the Chinese Academy of Sciences (CAS), the Kenya Wildlife Service (KWS) and the United Nations Environment Programme (UN Environment) jointly initiated the “Sustainable Management of Protected Areas in East Africa” project. This paper provides a brief overview of the project’s research background, goals and research tasks. The study is based on a look at the PA management system in East Africa and a review of the literature on the impact of PAs in the region. Results show that East African nations have expanded the coverage of PAs and established a complex set of PA management systems over the past century. The mandate for PAs in East African nations has changed recently from protecting biodiversity to alleviating poverty and supporting livelihoods. However, a combination of human activities and ecological processes inside and outside of PAs may not only impact biodiversity and ecosystem function over the long term, but also pose a threat to the capacity of PAs to maintain livelihoods and alleviate poverty in the local communities around them. The state of existing research in the field suggests there is an enormous need for additional research, the purpose of which is to help PA managers and policy-makers in East Africa understand how to achieve win-win outcomes for both ecosystems and human well-being. Against this background, the CAS-KWS-UN Environment joint research project aims to understand the dynamic interactions between ecosystems and human well-being around PAs in East Africa and identify good practices for PA management to reconcile conservation targets with the livelihood demands of local communities. It is intended that this research be shared with interested parties throughout the developing world. Significant progress has been made in the implementation of the project, in terms of data collection, exchanges of researchers, and the completion of case studies. In the coming year, success stories and examples of failures of PA management in the region will be systematically summarized and shared among scientists, managers and decision makers worldwide. Given its blueprint for building a “Beautiful China”, China can both supplement and benefit from East African knowledge and experience of PA management. This joint research effort promotes Sino-African cooperation on PA research and management.

The genus Sceloporus represents a diverse and ecologically significant group of lizards within the Mexican herpetofauna, particularly in the Trans-Mexican Volcanic Belt (TMVB), a region of exceptional endemism increasingly threatened by anthropogenic pressures. In this study, we conducted a comprehensive spatial vulnerability assessment of 17 species of Sceloporus that are present in the TMVB, integrating ecological niche modelling (ENM), habitat fragmentation metrics, land-use exposure and protected area overlap. Binary distribution maps were generated from the ensemble models optimised with biomod2. For each species, we calculated the habitat area, number of habitat patches and mean patch size, synthesising these values into a composite vulnerability index. Land-use pressures were quantified through spatial overlaying of urban, agricultural and pasture-land layers, followed by principal component analysis (PCA) and k-means clustering to generate a multivariate anthropogenic pressure zonation. Species distributions were also compared against those of state and federal protected areas. ​​The 17-species analysis revealed noteworthy variation in spatial dimensions and fragmentation of habitat, exhibiting high spatial vulnerability and high exposure to anthropogenic pressure. Furthermore, our results revealed that the predicted habitats of all 17 species overlap with highly transformed urban landscapes. A bivariate risk assessment identified S. megalepidurus as the only species with both high pressure and high vulnerability, while the species S. anahuacus, S. albiventris and S. minor, currently listed as “least concern” or “not evaluated” by the IUCN, showed alarming risk signals when spatially explicit metrics were incorporated. Our integrative framework underscores the need to revisit conservation assessments by incorporating habitat quality, fragmentation and exposure to land-use pressures, not just geographic range.

Area-based conservation is essential to safeguard nature’s diversity. In view of expanding human land use, increasing climate change and unmet conservation targets, area-based conservation requires efficiency and effectiveness more than ever. In this review, I identify and relate pressing challenges to promising opportunities for effective and efficient protected area governance and management, to enhance research, decision-making and capacity building in area-based conservation under uncertain future developments. I reveal that protected area management is particularly challenged by human land use, climate change, invasive species, and social, political and economic limitations. Protected area management often lacks the continuous availability of data on current states and trends of nature and threats. Biocultural conservation, climate-smart management and biosecurity approaches help to overcome challenges induced by human needs, climate change and invasive species, respectively. Economic valuation and shifts in funding priorities can boost protected area effectiveness and efficiency. In-situ monitoring techniques, remote sensing and open data infrastructures can fill data and information gaps for protected area planning and management. Moreover, adaptive management is an auspicious concept in the framework of systematic conservation planning to ensure the enduring effectiveness of protected areas despite unpredictable future developments. Post-2020 international biodiversity and sustainable development goals could be met earlier if protected areas were more effective. I consequently conclude with the need for a global information system that is to support area-based conservation by synthesizing challenges and opportunities for protected area management effectiveness and efficiency at the local to global level.

In the management of protected nature areas, arguments are being raised for increasingly integrated approaches. Despite an explicit ambition from the responsible managing governmental agencies, Swedish Environmental Protection Agency and Swedish National Heritage Board, attempts to initiate and increase the degree of integrated nature and cultural heritage conservation management in the Swedish mountains are failing. The delivery of environmental policy through the Swedish National Environmental Objective called Magnificent Mountains is dependent on increased collaboration between the state and local stakeholders. This study, using a group model building approach, maps out the system’s dynamic interactions between nature perceptions, values and the objectives of managing agencies and local stakeholders. It is identified that the dominance of a wilderness discourse influences both the objectives and management of the protected areas. This wilderness discourse functions as a barrier against including cultural heritage conservation aspects and local stakeholders in management, as wilderness-influenced objectives are defining protected areas as environments “untouched” by humans. A wilderness objective reduces the need for local knowledge and participation in environmental management. In reality, protected areas depend, to varying degrees, on the continuation of traditional land-use practices.

Protected areas are widely recognized as a cornerstone of biodiversity and natural resources management and sustainable development. Protected areas are a vital part of securing human prosperity and quality of life. In China, the legal framework for protected area management is scattered around various regulations. In order to better manage protected areas in China, the Chinese government has issued and revised some laws, regulations and policies on protected areas conservation and management. However, protected areas management is still facing some challenges. There is little legal literature on this issue and this paper tries to fill this gap. Firstly, it will briefly introduce the most relevant laws, regulations and policy on protected areas management. Secondly, it will analyze the recent challenges of protected areas management. Thirdly, some possible suggestions on how to better solve the recent challenges on protected areas management in China will be proposed. These suggestions include improving the management system, improving the relevant legislation, promoting public participation and establishing a diversified funding guarantee system.

Habitat loss from unrelenting human pressure is causing an unprecedented decline in global biodiversity. Protected areas (PAs) are meant to counteract loss and fragmentation of ecosystems and today PAs form the backbone of conservation strategies worldwide. However, anthropogenic climate change can severely reduce the effectiveness of PAs. Conservation professionals are in need of concrete spatial information on climatic changes within PAs in order to put forward practicable strategies to safeguard PA effectiveness in the face of climate change. In this study, we take advantage of openly accessible data on the disappearing climate index (DCI) to examine which PA characteristics are linked to climate change resilience on a global scale. DCI provides a measure of the relative area (percent of total area) within a PA that exhibits certain climatic conditions that will either disappear entirely or move outside the boundaries of the PA by the year 2070. Our results show that topographic diversity is highly correlated with reduced climate change impacts in PAs worldwide. We analyzed three different PA characteristics representing topographic diversity: PA area, maximal elevational difference (MED) and median terrain ruggedness (TR). All three characteristics are highly correlated with a decrease in the disappearing climate index (DCI). These results hold true across localities and even PA management practices. IUCN management category IV (habitat/species management area) and V (protected landscape/seascape) exhibit on average the highest DCI values. As an indicator for PA resilience under climate change, topographic diversity can be assessed easily through publicly available data and remote sensing products. This ease-of-use leaves topographic diversity standing in marked contrast to overall environmental diversity as an actionable conservation metric. Of course, topographic diversity alone is not a sufficient criterion on which to base conservation decisions. However, neither should the potential usefulness of topographic diversity be underestimated. As an actionable and complementary metric in combination with biological information topographic diversity can be an exceptional tool for decision making by PA managers, conservation practitioners and politicians.

Forest fragmentation can lead to habitat reduction, edge increase, and exposure to disturbances. A key emerging policy to protect forests is payments for ecosystem services (PES), which offers compensation to landowners for environmental stewardship. Mexico was one of the first countries to implement a broad-scale PES program, enrolling over 2.3Mha by 2010. However, Mexico's PES did not completely eliminate deforestation in enrolled parcels and could have increased incentives to hide deforestation in ways that increased fragmentation. We studied whether Mexican forests enrolled in the PES program had less forest fragmentation than those not enrolled, and whether the PES effects varied among forest types, among socioeconomic zones, or compared to the protected areas system. We analyzed forest cover maps from 2000 to 2012 to calculate forest fragmentation. We summarized fragmentation for different forest types and in four socioeconomic zones. We then used matching analysis to investigate the possible causal impacts of the PES on forests across Mexico and compared the effects of the PES program with that of protected areas. We found that the area covered by forest in Mexico decreased by 3.4% from 2000 to 2012, but there was 9.3% less forest core area. Change in forest cover was highest in the southern part of Mexico, and high-stature evergreen tropical forest lost the most core areas (-17%), while oak forest lost the least (-2%). Our matching analysis found that the PES program reduced both forest cover loss and forest fragmentation. Low-PES areas increased twice as much of the number of forest patches, forest edge, forest islets, and largest area of forest lost compared to high-PES areas. Compared to the protected areas system in Mexico, high-PES areas performed similarly in preventing fragmentation, but not as well as biosphere reserve core zones. We conclude that the PES was successful in slowing forest fragmentation at the regional and country level. However, the program could be improved by targeting areas where forest changes are more frequent, especially in southern Mexico. Fragmentation analyses should be implemented in other areas to monitor the outcomes of protection programs such as REDD+ and PES.
