Realizing “30 × 30” in India: The potential, the challenges, and the way forward

AbstractOf the goals and targets specified by the Kunming‐Montreal Global Biodiversity Framework, Target 3, often referred to as “30 × 30,” has garnered widespread attention globally. In this paper, we critique India's potential to meet this target. We find that with its vast network of ecosystems that are under some form of protection and through the recognition of other effective area‐based conservation measures sites, India has the potential to meet the quantitative target of conserving and managing at least 30% of its area by 2030. However, the qualitative attributes of the target might be more difficult to realize owing to several challenges, such as inadequate landscape connectivity, insufficient representation of habitats in the current protected area model, and the exacerbation of socioeconomic vulnerabilities of resource‐dependent communities. To achieve strategic, inclusive, and equitable conservation, we suggest a four‐pronged approach involving landscape‐level biodiversity conservation, socially just and collaborative safeguarding of biodiversity, and relevant policy (re)formulation, informed and underlain by long‐term research and impact monitoring. Although we focus on India, the issues we discuss are of broader relevance, especially for countries across the Global South that are also likely to be significantly impacted by the implementation of the target.

Geospatial investigation of site suitability for ecotourism development using AHP and GIS techniques in Uttara Kannada district, Karnataka state, India

The study aimed to spatially examine the viability and site suitability of ecotourism in the Uttara Kannada district, India. Karnataka is a fantastic destination for a variety of travel and has a lot of potentials to promote ecotourism, which has acquired popularity in recent years. Ecotourism is important to the conservation and safeguarding of biodiversity. Consequently, the current research aims to find potential ecotourism areas in the Uttara Kannada district, utilizing the analytic hierarchy process (AHP) and Geographical Information System-Remote sensing (GIS-RS) methodologies. The study is based on the application of GIS-RS factors for landscape naturalness, climatic features, accessibility parameters, topographic attributes, protected and reserved regions, and natural attractiveness in the GIS platform via a weighted overlay method. To analyze and appraise the ecotourism potential in the study area, the research uses satellite and weighted overlays of auxiliary data from AHP. As an outcome, 53.54 % of the highly suitable land was found over the forest regions and finally, the Unsuitable regions were mainly indicated over the miscellaneous area (47.46 %). The majority of the most suitable ecotourism sites that fall under category S1 are located in the Taluks like Joida (27 %) and Karwar (15 %). The outcome of this paper as expected is that very high and moderately suitable regions were initiated in the forest region. The study's findings and methodology will be useful to decision-makers and planners.

Global assessment of the biodiversity safeguards of development banks that finance infrastructure.

Infrastructure development is a major driver of biodiversity loss globally. With upward of US$2.5 trillion in annual investments in infrastructure, the financial sector indirectly drives this biodiversity loss. At the same time, biodiversity safeguards (project-level biodiversity impact mitigation requirements) of infrastructure financiers can help limit this damage. The coverage and harmonization of biodiversity safeguards are important factors in their effectiveness and therefore warrant scrutiny. It isequally important to examine the extent to which these safeguards align with best-practice principles for biodiversity impact mitigation outlined in international policies, such as that of the International Union for Conservation of Nature. We assessed the biodiversity safeguards of public development banks and development finance institutions for coverage, harmonization, and alignment with best practice. We used Institute of New Structural Economics and Agence Française de Développement's global database to identify development banks that invest in high-biodiversity-footprint infrastructure and have over US$500 million in assets. Of the 155 banks, 42% (n=65) had biodiversity safeguards. Of the existing safeguards, 86% (56 of 65) were harmonized with International Finance Corporation (IFC) Performance Standard 6 (PS6). The IFC PS6 (and by extension the 56 safeguard policies harmonized with it) had high alignment with international best practice in biodiversity impact mitigation, whereas the remaining 8 exhibited partial alignment, incorporating few principles that clarify the conditions for effective biodiversity offsetting. Given their dual role in setting benchmarks and leveraging private finance, infrastructure financiers in development finance need to adopt best-practice biodiversity safeguards if the tide of global biodiversity loss is to be stemmed. The IFC PS6, if strengthened, can act as a useful template for other financier safeguards. The high degree of harmonization among safeguards is promising, pointing to a potential for diffusion of practices.

Lianas (Vitis spp.) reduce growth and carbon sequestration of light‐demanding tree species in a temperate forest

Governments worldwide are seeking natural climate solutions that can provide economic stimulus while meeting climate goals. Forests provide essential carbon dioxide (CO2) sequestration services, but their potential may be limited by elevated liana densities often resulting from human disturbance. Here we report the first estimate of liana (Vitis spp.) impacts on CO2 removal rates by trees in temperate Appalachian forests and suggest liana removal with biodiversity safeguards as a potential strategy for improved forest management. Shade‐intolerant tree species without lianas removed CO2 20% faster than conspecifics with lianas (p = 0.025). We did not detect significant impacts of liana presence on the CO2 removal rates for shade‐tolerant species (p = 0.838). Additionally, the merchantable boles of trees without lianas increased in volume 9% faster annually compared to trees with lianas, for all species (p = 0.003). Our findings indicate that thinning lianas—particularly from light‐loving species such as Liriodendron tulipifera—may improve sustainability of forest management and increase carbon storage while mitigating climate change.

How do consumers perceive open‐source seed licenses? Exploring a new credence attribute

AbstractCritical consumerism is the conscious choice of purchasing or avoiding products for ethical or environmental reasons. As an increasing share of consumer attempts to purchase sustainably produced food, credence attributes, which are product qualities that are not easily observable or verifiable during purchase or consumption, gain importance. Variety ownership has so far not played any role in food consumption choices but is a new type of credence attribute that may gain relevance through the recent introduction of open‐source seed licenses. Such licenses aim to safeguard agrobiodiversity, ensure long‐term access to plant genetic resources and counter current privatization trends in the seed industry. The labeling of open‐source produce could help to upscale the concept and enable consumers to support the safeguarding of biodiversity through their consumption choices. However, as the first open‐source varieties become available for purchase, consumers’ perspectives on open‐source seed licenses remain unclear. In this paper, we, hence, examine German consumers’ perceptions of open‐source seed licenses. The analysis of 228 thinking‐aloud protocols, based on qualitative data collected in a conventional and an organic supermarket in Berlin, Germany, serves as an empirical basis. We find that most consumers have a highly positive evaluation of open‐source seed licenses, regardless of whether they fully understand the concept or not. The license is widely perceived to provide a counter‐model to current industrial seed‐ and agricultural production. Specifically, it is believed to (1) prevent the privatization of plant genetic resources, (2) contribute to the conservation and enhancement of agrobiodiversity, (3) support (small‐scale) farmers and (4) prevent market concentration. To what extent these perceptions coincide with personal preferences for taste, health, safety and quality remains to be explored. The concept may specifically cater to certain consumer segments, including highly educated, young to middle‐aged, organically minded consumers.

Aromatic and medicinal plants used in traditional medicine in the region of Tiaret, North West of Algeria

Herbal medicine is gaining an increasing importance in the management of various ailments, but little is known about traditional practices in Algeria. This ethnopharmacological study aims to document medicinal and aromatic plants used in traditional medicine in the region of Tiaret (northwest of Algeria) in order to contribute to safeguard the local pharmacopoeia as cultural heritage, and to provide a scientific basis for developing novel strategies for such practices which can help for drugs discovery. Semi-structured interviews with 64 traditional healers and herbalists were realized in the region of Tiaret (Algeria) throughout field studies achieved from December 2018 to May 2020. Interviews covered sociodemographic information, popular and vernacular names of the medicinal plants, mode of use and toxicity among other data. Results reveal the use of 107 plant species belonging to 45 families and 97 genera for the treatment of various ailments. Lamiaceae, Apiaceae and Asteraceae were the most represented families. The most frequently cited species were Senna alexandrina Mill. (FC=27), Atriplex halimus L. and Bunium incrassatum Amo (FC=23 each), Foeniculum vulgare Mill. (FC=22), and Matricaria chamomilla L. (FC=21). However, the higher use values were reported for Nigella sativa L. (UV=1.5), Trigonella foenum-graecum L. (UV=1.38), Thymus serpyllum L. (UV=1.2), Ziziphus lotus (L.) Lam. (UV=1.14), Urtica dioica L. (1.13), and Senna alexandrina Mill. (UV=0.52) respectively. Interestingly, Bunium incrassatum Amo, Echinops spinosissimus Turra, Cucurbita moschata Duchesne, Pennisetum glaucum (L.) R.Br and Malus domestica Borkh. were reported for the first time as medicinal plants in the north Africa and Algeria. Moreover, 246 new therapeutic uses were described. It should be noted that Pistacia atlantica Desf., Tetraclinis articulata (Vahl) Mast., Oudneya africana R. Br., Euphorbia guyoniana Boiss. & Reut, Teucrium polium L. and Marrubium deserti (Noë) Coss. are endemic to North Africa-Algeria, Northern and Central Sahara. Furthermore, Artemisia herba-alba Asso, Anacyclus pyrethrum (L.) Lag., Cuminum cyminum L., Saussurea costus (Falc.) Lipsch., Boswellia sacra Flueck. and Pistacia atlantica Desf. are considered threatened, rare or endangered species. Our findings are relevant not only for the future studies and experiments in the search for novel compounds, but also for the safeguard of traditional knowledge and biodiversity.

Unlocking the Entomological Collection of the Natural History Museum of Maputo, Mozambique

BackgroundThe collections of the Natural History Museum of Maputo have a crucial role in the safeguarding of Mozambique's biodiversity, representing an important repository of data and materials regarding the natural heritage of the country. In this paper, a dataset is described, based on the Museum’s Entomological Collection recording 409 species belonging to seven orders and 48 families. Each specimen’s available data, such as geographical coordinates and taxonomic information, have been digitised to build the dataset. The specimens included in the dataset were obtained between 1914–2018 by collectors and researchers from the Natural History Museum of Maputo (once known as “Museu Alváro de Castro”) in all the country’s provinces, with the exception of Cabo Delgado Province.New informationThis paper adds data to the Biodiversity Network of Mozambique and the Global Biodiversity Information Facility, within the objectives of the SECOSUD II Project and the Biodiversity Information for Development Programme. The aforementioned insect dataset is available on the GBIF Engine data portal (https://doi.org/10.15468/j8ikhb). Data were also shared on the Mozambican national portal of biodiversity data BioNoMo (https://bionomo.openscidata.org), developed by SECOSUD II Project.

Soil Arthropod Responses in Agroecosystem: Implications of Different Management and Cropping Systems

The EU’s Common Agricultural Policy (CAP 2014–2020) on soil management points to the combination of sustainable food production with environmental protection, reduction of CO2 emissions, and safeguarding of soil biodiversity. In this study, three farms (in the Emilia-Romagna region), managed with both conventional and conservation practices (the last ones with and without sub-irrigation systems), were monitored from 2014 to 2017 to highlight the impact of different crops and soil managements on soil arthropods, in terms of abundance, composition, and soil biological quality (applying QBS-ar index). To do this, linear mixed models were performed, whereas arthropods assemblages were studied through PERMANOVA and SIMPER analysis. Soil communities varied among farms, although most differences were found among crops depending on management practices. Nonetheless, conservation systems and a wider reduction in anthropogenic practices provided better conditions for soil fauna, enhancing QBS-ar. Moreover, arthropod groups responded to soil practices differently, highlighting their sensitivity to agricultural management. Community assemblages in corn and wheat differed between managements, mainly due to Acari and Collembola, respectively. In conservation management, wheat showed the overall greatest abundance of arthropods, owing to the great number of Acari, Collembola, and Hymenoptera, while the number of arthropod groups were generally higher in crop residues of forage.

Italian local goat breeds have better milk coagulation properties than cosmopolitan breed

Native goat breeds play an important role both in the safeguarding of biodiversity and the development of local economy. This study aimed to evaluate milk coagulation properties (MCP) of local (Garganica, Girgentana, Maltese, Mediterranean Red) and cosmopolitan (Saanen) goat breeds. From May to August 2018, 46 goats were sampled monthly in an experimental farm; milk samples were analysed for fat, protein and lactose percentages, pH, SCC and MCP. Data were evaluated through a mixed linear model with repeated measures, including breed, month of lactation and parity as fixed effects. Month of lactation affected all studied traits, and breed affected MCP, protein percentage, lactose percentage and pH. Milk composition and coagulation properties were better in local breeds than Saanen. In particular, milk of local breeds was richer in protein percentage, and coagulated and reached 20 mm of curd firmness on average 3.14 and 2.56 min earlier than Saanen, respectively. Moreover, the firmest curd was observed in Girgentana (31.44 mm) and the weakest in Garganica (21.72 mm). Rennet coagulation time and curd firmness decreased towards the end of lactation, differing significantly between May (10.62 min and 31.69 mm, respectively) and August (8.33 min and 20.69 mm, respectively), whereas curd-firming time only differed between May and June–July. In conclusion, milk of local breeds showed better milk coagulation ability than the cosmopolitan breed. Highlights Breed and month of lactation were important sources of variation of goat MCP. Local goat breeds showed better MCP than Saanen. Valorisation of the milk from the local breeds might be a tool to preserve native genetic resources.

Best-practice biodiversity safeguards for Belt and Road Initiative’s financiers

With thousands of projects being built along eight transcontinental corridors, China’s Belt and Road Initiative (BRI) is driving the global infrastructure boom. BRI is likely to have a sizeable biodiversity footprint as its corridors overlap several priority areas for conservation and 150,000 km2 of critical habitat. Biodiversity safeguards for the initiative therefore warrant scrutiny. Biodiversity safeguards are policies or standards (adopted by regulators, project proponents or financiers) that specify biodiversity impact mitigation measures. Here we examine a key source of safeguards—lending requirements of BRI’s financiers. We compare them with International Finance Corporation’s Performance Standard 6, which is often regarded as international best practice and which requires projects affecting ‘critical habitat’ to achieve a ‘net gain’ of biodiversity through impact mitigation. We find that of the 65 financiers identified (35 Chinese and 30 international), just 17 require biodiversity impact mitigation and 12 require a ‘net gain’. Among those with biodiversity safeguards, 16 are international, and despite the Chinese financiers accounting for over 90% of BRI’s financing (by quantum of investment), only 1 of the 35 we identified has biodiversity safeguards. Because most BRI finance is not subject to biodiversity safeguards, we conclude that potential impacts of BRI linear infrastructure projects may remain unmitigated, despite approximately 369,000 km2 of critical and natural habitat occurring within the 25 km buffer zone of such projects. We therefore argue for urgent adherence to best-practice safeguards for all institutions financing the BRI. An analysis reveals only 17 out of 65 financiers require biodiversity impact mitigation measures, and overall the initiative falls short of international best practices

Step back from the forest and step up to the Bonn Challenge: how a broad ecological perspective can promote successful landscape restoration

We currently face both an extinction and a biome crisis embedded in a changing climate. Many biodiverse ecosystems are being lost at far higher rates than they are being protected or ecologically restored. At the same time, natural climate solutions offer opportunities to restore biodiversity while mitigating climate change. The Bonn Challenge is a U.N. programme to restore biodiversity and mitigate climate change through restoration of the world's degraded landscapes. It provides an unprecedented chance for ecological restoration to become a linchpin tool for addressing many environmental issues. Unfortunately, the Forest and Landscape Restoration programme that underpins the Bonn Challenge, as its name suggests, remains focused on trees and forests, despite rising evidence that many non‐forest ecosystems also offer strong restoration potential for biodiversity and climate mitigation. We see a need for restoration to step back to be more inclusive of different ecosystem types and to step up to provide integrated scientific knowledge to inform large‐scale restoration. Stepping back and up will require assessments of where to restore what species, with recognition that in many landscapes multiple habitat types should be restored. In the process, trade‐offs in the delivery of different ecosystem services (e.g. carbon, biodiversity, water, albedo, livestock forage) should be clearly addressed. We recommend that biodiversity safeguards be included in policy and implemented in practice, to avoid undermining the biophysical relationships that provide ecosystem resilience to climate change. For ecological restoration to contribute to international policy goals will require integrated large‐scale science that works across biome boundaries.

Large-Scale Mapping of Tree-Community Composition as a Surrogate of Forest Degradation in Bornean Tropical Rain Forests

Assessment of the progress of the Aichi Biodiversity Targets set by the Convention on Biological Diversity (CBD) and the safeguarding of ecosystems from the perverse negative impacts caused by Reducing Emissions from Deforestation and Forest Degradation Plus (REDD+) requires the development of spatiotemporally robust and sensitive indicators of biodiversity and ecosystem health. Recently, it has been proposed that tree-community composition based on count-plot surveys could serve as a robust, sensitive, and cost-effective indicator for forest intactness in Bornean logged-over rain forests. In this study, we developed an algorithm to map tree-community composition across the entire landscape based on Landsat imagery. We targeted six forest management units (FMUs), each of which ranged from 50,000 to 100,000 ha in area, covering a broad geographic range spanning the most area of Borneo. Approximately fifty 20 m-radius circular plots were established in each FMU, and the differences in tree-community composition at a genus level among plots were examined for trees with diameter at breast height ≥10 cm using an ordination with non-metric multidimensional scaling (nMDS). Subsequently, we developed a linear regression model based on Landsat metrics (e.g., reflectance value, vegetation indices and textures) to explain the nMDS axis-1 scores of the plots, and extrapolated the model to the landscape to establish a tree-community composition map in each FMU. The adjusted R2 values based on a cross-validation approach between the predicted and observed nMDS axis-1 scores indicated a close correlation, ranging from 0.54 to 0.69. Histograms of the frequency distributions of extrapolated nMDS axis-1 scores were derived from each map and used to quantitatively diagnose the forest intactness of the FMUs. Our study indicated that tree-community composition, which was reported as a robust indicator of forest intactness, could be mapped at a landscape level to quantitatively assess the spatial patterns of intactness in Bornean rain forests. Our approach can be used for large-scale assessments of tree diversity and forest intactness to monitor both the progress of Aichi Biodiversity Targets and the effectiveness of REDD+ biodiversity safeguards in production forests in the tropics.

GBIS: the information system of the German Genebank.

The German Federal ex situ Genebank of Agricultural and Horticultural Crop Species is the largest collection of its kind in the countries of the European Union and amongst the 10 largest collections worldwide. Beside its enormous scientific value as a safeguard of plant biodiversity, the plant genetic resources maintained are also of high importance for breeders to provide new impulses. The complex processes of managing such a collection are supported by the Genebank Information System (GBIS). GBIS is an important source of information for researchers and plant breeders, e.g. for identifying appropriate germplasm for breeding purposes. In addition, the access to genebank material as a sovereign task is also of high interest to the general public. Moreover, GBIS acts as a data source for global information systems, such as the Global Biodiversity Information Facility (GBIF) or the European Search Catalogue for Plant Genetic Resources (EURISCO).Database URL: http://gbis.ipk-gatersleben.de/

Impacts of Logging Road Networks on Dung Beetles and Small Mammals in a Malaysian Production Forest: Implications for Biodiversity Safeguards

Various international bodies and non-governmental organizations (NGOs) have proposed guidelines for safeguarding biodiversity. Nevertheless, quantitative criteria for safeguarding biodiversity should first be established to measure the attainment of biodiversity conservation if biodiversity is to be safeguarded effectively. We conducted research on the impact of logging on biodiversity of dung beetles and small mammals in a production forest in Temengor Forest Reserve, Perak, Malaysia. This was done to develop such quantitative criteria for Malaysian production forests while paying special attention to the effects of road networks, such as skid trails, logging roads, and log yards, on biodiversity. Species assemblages of dung beetles as well as small mammals along and adjacent to road networks were significantly different from those in forest interiors. Therefore, minimizing the road network density will contribute to retaining biodiversity; this will allow us to use road network density as a quantitative criterion for safeguarding biodiversity in production forests. Additionally, road network density is easily measurable and verifiable by remote sensing, which enables us to check the implementation of the criteria.

Restoration Reserves as Biodiversity Safeguards in Human-Modified Landscapes

Globally, human populations are rapidly converting large blocks of tropical old-growth forests into ragged quilts of small forest patches, embedded within human-modified landscapes, consisting mostly of agricultural fields and pasture lands (Chazdon et al. 2009). Such landscapes impose a myriad of threats to native biodiversity, including those related to habitat loss and fragmentation, overexploitation of forest resources and matrix-mediated perturbations (Gardner et al. 2009). As human-modified landscapes exhibit increasing levels of biotic impoverishment and homogenization (Lobo et al. 2011), scientists, environmentalists, and policy makers are looking for a modus vivendi between conservation and ongoing human demands for land (Phalan et al. 2011).

The interim REDD + Partnership: Boost for biodiversity safeguards?

Despite the unsatisfactory progress under the UNFCCC, the REDD+ debate has raised hopes for successfully tackling the unsustainable use of forests in developing countries. However, its approach of focusing on the sequestration capacity of forests is potentially at odds with other environmental objectives. In order to cope with the risk of unintended impacts on biodiversity, the UNFCCC agreed on environmental safeguards that have yet to be specified and implemented through national REDD+ strategies. Employing theoretical considerations regarding non-binding institutions and transparency, we investigate whether and how the voluntary setting of the REDD+ Partnership can support the development of effective environmental safeguards.The analysis shows that the Partnership, despite its non-binding features, represents a promising complementary policy approach to the UNFCCC. Consisting of public and private actors it has laid the foundation for a more comprehensive view on REDD+ by focusing on information exchange on practical implementation issues, e.g. on the specification of the safeguards agreed under the UNFCCC. If efforts to ensure accountability through transparency and stakeholder inclusiveness can be further improved, the setting may significantly contribute to establishing horizontal accountability, and hence, trigger a ‘race to the top’ on environmental standards.

A framework for integrating biodiversity concerns into national REDD+ programmes

The UNFCCC mechanism for Reducing Emissions from Deforestation and Degradation in developing countries (REDD+) represents an unprecedented opportunity for the conservation of forest biodiversity. Nevertheless, there are widespread concerns surrounding the possibility of negative environmental outcomes if biodiversity is not given adequate consideration throughout the REDD+ process. We propose a general framework for incorporating biodiversity concerns into national REDD+ programmes based on well-established ecological principles and experiences. First, we identify how biodiversity distribution and threat data, together with data on biodiversity responses to forest change and management, can be readily incorporated into the strategic planning process for REDD+ in order to identify priority areas and activities for investment that will deliver returns for both carbon and biodiversity. Second, we propose that assessments of changes in biodiversity following REDD+ implementation could be greatly facilitated by paralleling, where possible, the existing IPCC architecture for assessing carbon emissions. A three-tiered approach is proposed for biodiversity assessment, where lower tiers can provide a realistic starting point for countries with fewer data and lower technical capacities. Planning and assessment of biodiversity safeguards for REDD+ need not overburden an already encumbered UNFCCC process. Immediate progress is already possible for a large number of developing countries, and a gradual, phased approach to implementation would minimise risks and facilitate the protection of additional biodiversity benefits from REDD+ activities. Greater levels of coordination between the UNFCCC and CBD, as well as other agencies and stakeholder groups interested in forest conservation are needed if biodiversity safeguards are to be fully adopted and implemented.

BIODIVERSITY OF SICILIAN FRUIT TREES: STUDIES ON PLUMS

The Sicilian territory contains a wide reserve of biodiversity of fruit tree species that, over a period of several centuries, have found there propitious pedoclimatic conditions for their establishment, and genetic diversification. The indigenous germplasm characterized Sicilian agriculture until less than one century ago but, after the diffusion of new cultivars originating from genetic improvement programs, a great part of this germplasm was replaced and now these important resources are at high risk of genetic erosion. Recently, public interest in the safeguarding of biodiversity and the development of a new interest in genetic resources and their scientific, economic and cultural importance, inspired several political actions aimed at the valorisation and conservation of this material. The present study, funded by the Sicilian government, aims to improve knowledge concerning Sicilian plum germplasm, which accounts for a great number of the accessions on the Island, through an action of characterization that includes various steps: biometric, qualitative and nutraceutical. The study was preliminarily carried out on 26 accessions as a preliminary study to facilitate the development of an efficient methodology prior to extending it to other accessions localized in the Sicilian territory.
