    Field investigation carried out by the Sicilian botanists in the last 20 years enabled them to identify eight habitat types of high biogeographic and conservation interest, neglected by the Directive 92/43, which deserve ad hoc conservation measures. For each of these habitats, a syntaxonomic interpretation of the corresponding plant communities, their main ecological, physiognomic and syndynamic traits and a list of diagnostic species are provided. Their classification into the macrotypes listed in the Annex I of the Directive 92/43 and the respective correspondence in EUNIS habitat classification are proposed. The habitats here described integrate those already proposed by the Italian Botanical Society, with the hope of an adequate recognition at national at supranational level.

    The evaluation of the effects of conservation agriculture during the transition from conventional tillage to no-tillage requires numerous indicators to be considered. For this purpose, we monitored changes in a multi-parameter dataset during a three-year experiment that combined three tillage intensities (conventional tillage—CT; minimum tillage—MT; and no tillage—NT) with three soil covering managements (tillage radish cover crop, winter wheat cover crop and bare soil). Using a multivariate analysis, we developed a Relative Sustainability Index (RSI) based on 11 physical (e.g., bulk density and penetration resistance), chemical (e.g., soil organic carbon and pH) and biological soil properties (e.g., earthworm density) to evaluate cropping systems sustainability. The RSI was most affected by tillage intensity showing higher RSI values (i.e., better performances) in reduced tillage systems. Specifically, the RSI under NT was 42% greater than that of CT and 13% greater than that of MT. Soil covering had little impact on the RSI. Among the tested parameters, the RSI was increased most by saturated hydraulic conductivity (+193%) and earthworm density (+339%) across CT and NT treatments. Our results suggest that conservation agriculture and, particularly, reduced tillage systems, have the potential to increase farm environmental and agronomic sustainability.

    Purpose Eco-museums safeguard the cultural authenticity and the historical identity of the place in which they operate. Conventional organizational models and management practices are generally employed to achieve this institutional aim. Conversely, innovative solutions – such as digitization – are overlooked. Adopting a service quality management perspective, the article intends to examine the role of managerialization and professionalization in triggering eco-museums' digitization. Design/methodology/approach An empirical analysis involving 126 eco-museums operating in Italy as of 2018 was designed to investigate the implications of managerialization and professionalization on the eco-museums' propensity to embark on a digitization process. Two different forms of digitization were examined: (1) the presence of eco-museums in the digital environment; and (2) the exploitation of digital tools for service delivery. The mediating role of two “soft” total quality management (TQM) practices, i.e. people centredness and strategic focus on visitors' experience, was contemplated in the empirical analysis. Findings The research findings suggest that managerialization and professionalization have ambiguous effects on eco-museums' digitization. Nevertheless, they indirectly contribute to a greater digital presence of eco-museums and to a larger use of digital tools for service delivery through an increased use of soft TQM practices. Research limitations/implications Managerialization and professionalization are likely to foster the digital transition of eco-museums, which advances their ability to protect and promote the local cultural heritage. Soft TQM practices intended to achieve people-centredness and to enhance the visitors' experience should be exploited to stimulate the eco-museums' digitization. Originality/value The article examines the triggers of eco-museums' digitization, providing some food for thought to scholars and practitioners.

    Fodder galega (Galega orientalis) is a perennial, wintering plant with great potential for agricultural development. The species has a large yield potential and exceptional adaptability to various environmental conditions. The sensitivity of G. orientalis to herbicides, however, as well as the photosynthetic performance of the species, are generally unknown. Our study aimed to evaluate the effects of the application of selected phenoxy herbicides (MCPA, MCPB) and the imidazoline family herbicide (IMA) on the parameters of primary photosynthetic processes as understood through fast chlorophyll fluorescence kinetics (OJIP). The effect of cultivation temperature was also investigated in the plants grown at 5, 18 and 25 °C. Time courses of OJIP-derived parameters describing photosystem II functioning after foliar application revealed that the plants showed negative responses to the herbicides in the order MCPB–MCPA–IMA within 24 h after the application. The application of herbicides decreased the values of maximum chlorophyll fluorescence (FM) and increased minimum fluorescence (F0), which led to a reduction in the maximal efficiency of PSII (FV/FM). Applications of MCPA and MCPB decreased variable chlorophyll fluorescence at 2 ms (VJ), 30 ms (VI) and VP, as well as the performance index (PIABS), which is considered a vitality proxy. The application increased absorption flux (ABS/RC), trapped energy flux (TRo/RC) and dissipated energy flux (DIo/RC). The effects were more pronounced in plants grown at 18 and 25 °C. The study revealed that the OJIP-derived parameters sensitively reflected an early response of G. orientalis to the foliar application of herbicides. Negative responses of PSII were more apparent in MCPA- and MCPB- exposed plants than IMA-exposed plants.

    A conservação das florestas é de grande interesse de toda a sociedade, pois garante os serviços ambientais básicos que sustentam a vida e a economia do país. Nesse estudo, realizou-se um diagnóstico do uso da terra e cobertura vegetal visando avaliar os conflitos entre as atividades antrópicas e as áreas de vegetação nativa remanescente de Cerrado na sub-bacia do Córrego do Veado e propor ações de adequação, do ponto de vista da conservação dos recursos naturais e da biodiversidade, com base na legislação pertinente e nas características físicas da bacia. O estudo se baseou em imagens orbitais e dados vetoriais, processados em Sistema de Informação Geográfica para a geração de produtos cartográficos. Na bacia, foram registradas 81 propriedades rurais, a maioria composta de imóveis com menos de quatro módulos fiscais, onde a principal forma de uso da terra foi a Pastagem sobre áreas consolidadas. A bacia contém em torno de 20% da área coberta por vegetação nativa de Cerrado, porém grande parte das propriedades não apresenta área de Reserva Legal e muitas nascentes de afluentes e do Córrego encontram-se degradadas. As ações propostas referem-se à recuperação das faixas de vegetação ciliar que descumprem o mínimo de largura estabelecido pela legislação, e das áreas de Reserva Legal; à readequação do uso em áreas voltadas à conservação da biodiversidade e à avaliação do potencial turístico da região, como forma de uso sustentável em áreas com alta declividade, solos altamente erodíveis e onde a vegetação de Cerrado encontra-se preservada. The conservation of forests is of great interest to all of society, as it guarantees the basic environmental services that support the life and economy of the country. In this study, a diagnosis of land use and vegetation cover was carried out in order to assess the conflicts between human activities and the areas of native Cerrado remnant in the sub-basin of the Córrego do Veado and propose adaptation actions, from the point of view of the conservation of natural resources and biodiversity, based on the legislation and the physical characteristics of the basin. The study was based on orbital images and vector data, processed in a Geographic Information System for the generation of cartographic products. In the basin, 81 rural properties were registered, the majority consisting of properties with less than four fiscal modules, where the main form of land use was Pasture over consolidated areas. The basin contains around 20% of the area covered by native Cerrado vegetation, however most of the properties do not have a Legal Reserve area and many tributary and stream springs are degraded. The proposed actions refer to the recovery of the strips of riparian vegetation that do not comply with the minimum width established by the legislation, and the areas of Legal Reserve; the readjustment of use in areas aimed at the conservation of biodiversity and the evaluation of the tourist potential of the region, as a form of sustainable use in areas with high declivity, highly erodible soils and where the Cerrado vegetation is preserved.Keywords:River Basin, Conservation, Ecosystem Service, Forest Code.

    This study explores the asymmetric effect on the rupiah exchange rate on every subsector agriculture export in Indonesia during 2006-2020. The non-linear ARDL method is used in this study to analyze the asymmetric relationship between exchange rate and export. NARDL method includes short-run and long-run coefficient estimates and embraces the asymmetric effect. The previous studies generally used the linear models on the aggregated data and ignored the differences in each export of the agricultural sub-sector, then they offered ambiguous results. The latest studies have preferred to use the method of NARDL on the agricultural sector in general data. Instead of using agricultural export data for each subsector, this paper considers subsector export data of agriculture. The estimated NARDL results indicate an asymmetric effect of the rupiah exchange rate on exports of the agricultural sub-sector in the long run. In general, there is no asymmetric effect in the short run. Generally, depreciation and appreciation of the Rupiah have a negative effect on exports of the agricultural sub-sector in the long run. However, rupiah appreciation positively impacts lag 2, and depreciation caused a different effect on each sub-sector. The NARDL results suggest that positive movements have lesser impacts than those of negative movements in the exchange rate on the agriculture sector both in the short and long run

    Enteric methane (CH4) emitted by ruminant species is known as one of the main greenhouse gases produced by the agricultural sector. The objective of this study was to assess the potential the potential for CH4 mitigation and additionally the chemical composition, in vitro gas production, dry matter degradation (DMD), digestibility and CO2 production of five tropical tree species with novel forage potential including: Spondias mombin, Acacia pennatula, Parmentiera aculeata, Brosimum alicastrum and Bursera simaruba mixed at two levels of inclusion (15 and 30%) with a tropical grass (Pennisetum purpureum). The forage samples were incubated for 48 h, and a randomized complete block design was used. Crude protein content was similar across treatments (135 ± 42 g kg−1 DM), while P. purpureum was characterized by a high content of acid detergent fiber (335.9 g kg−1 DM) and B. simaruba by a high concentration of condensed tannins (20 g kg−1 DM). Likewise, A. pennatula and P. aculeata were characterized by a high content of cyanogenic glycosides and alkaloids respectively. Treatments SM30-PP70 (30% S. mombin + 70% P. purpureum) and BA30-PP70 (30% B. alicastrum + 70% P. purpureum) resulted in superior degradability at 48h than P. purpureum, while in the AP30-PP70 (30% A. pennatula + 70% P. purpureum) was lower than the control treatment (p ≤ 0.05). At 24 and 48 h, treatments that contained P. aculeata and B. alicastrum yield higher CH4 mL g−1 DOM than P. purpureum (p ≤ 0.05). The inclusion of these forage species had no statistical effect on the reduction of CH4 emissions per unit of DM incubated or degraded at 24 and 48 h with respect to P. purpureum although reductions were observed. The use of fodders locally available is an economic and viable strategy for the mitigation of the environmental impact generated from tropical livestock systems.
