“…Asimismo, en la medida en que se utilicen gramíneas leguminosas asociadas con mayor densidad de árboles y arbustos como fuente de forraje, estos ayudan a almacenar carbono, fijación simbiótica del nitrógeno atmosférico al suelo por las leguminosas, aumentan el bienestar y la producción animal (29,40), y de esta manera mejorar la sostenibilidad del sistema. La intensificación de las prácticas agro-pastorales se ve como una forma de reducir la presión sobre los bosques nativos (41), causada por el aumento de la agricultura intensiva que se incentiva por una mayor expansión del uso de monocultivos y el pastoreo incidiendo en las fronteras forestales. En los sistemas de producción extensiva, los animales son libres de moverse, lo que permite mejores actividades fisiológicas y funciones de comportamiento.…”

In the small ruminant sector, there is a great interest in measuring and improving their production systems and their environmental performance, since its great adaptability and inhabits a wide variety of ecosystems, with a great biodiversity of food resources, grazing in turn, generates economic-productive and environmental benefits. However, unplanned management and overexploitation of the natural resources of these areas have caused erosion, water depletion and even desertification, in the same manner intensive production systems and intensive agriculture that feeds these farming systems. To compare scientific innovations in the sustainability of the different production systems of small ruminants a bibliometric analysis was carried out to describe the advantages and disadvantages of the management of extensive, semi-intensive and intensive-stable production systems in the sustainability of small ruminants. There is concern in society about the environmental impact of animal production systems and that these have been carried out in a sustainable way. This trend influences the production of sheep, goats, and white-tailed deer, which are develop in intensive, semi-extensive and extensive systems. Due to the pressure to increase the volume and efficiency of production and to cope with demand, intensive systems are best suited, but face greater environmental such emission of greenhouse gases (GHGs), which contribute to global warming and animal environmental problems. On the other hand, semi-extensive and extensive systems also emit GHGs, however are associated with greater animal welfare and cleaner production. However, are affected by seasonal variations for forage production to maintain production levels.

“…In this study, we provide the perspective of landscape connectivity to discuss buffer zone delineation in nature reserves. Some related researches provided suggestions through AHP technique and by establishing ecological corridors; however, species activities and quantified indices for effect verification were considered insufficiently [7,10]. De Matos [11] developed a forest sustainability index on the basis of landscape structural factors; however, the function of each patch was difficult to obtain without using patch importance indices such as dPC.…”

“…However, since habitat fragmentation has become one of the key drivers of species loss worldwide [9], buffer zones should be planned considering their ability to maintain not only habitat quality but also connectivity. Brayan [10] conducted research in Rio Doce State Park on recovering connectivity by establishing ecological corridors in buffer zones, reforestation, and environmental enrichment; nevertheless, few quantitative indices were applied to verify the effects of these efforts. The latest study by Dematos [11] developed a forest sustainability index on the basis of landscape structural factors to determine the best plans for landscape restoration in protected areas and their surroundings, while the study did not focus on different functions of patches in maintaining connectivity.…”

Since habitat fragmentation results in species losses worldwide, considering the influence of buffer zones on the maintenance of connectivity provides a new perspective for buffer delimitation. In our study, the implications of buffer zones around nature reserves were studied at four sites in Fuzhou from the perspective of landscape connectivity based on a distance threshold of 1 km. We applied Graph-based connectivity indices at the landscape level and patch level to reveal the overall connectivity and patterns of change in patch importance for maintaining connectivity with various buffer zones. Based on the results of these analyses, we showed the relationship between structural factors and changes in patch importance by Spearman correlation analysis and redundancy analysis. The results indicate that in the sites with smaller habitat proportion (HP), the connectivity is relatively lower, and the changes in patch importance will be greater when the buffer zone increases. Different buffer zone sizes are suggested in four sites to maximize its benefits. Relatively small patches with high shape complexity and close proximity to patches outside the boundary contribute greatly to connectivity by acting as stepping stones.

“…They often have ambiguous rules, making their establishment and management a complicated task for both government and non-government agencies [50,51]. However, they provide a number of important functions, such as increasing the amount of available habitat and connectivity between forest fragments, enhancing the conservation of species with high mobility, acting as physical barriers to human encroachment, reducing edge effects, and enhancing environmental services provided by the PA [51][52][53]. Because of their role in the protection or re-allocation of land away from agricultural or other land use, historically the formal establishment of ecological corridors has not been without contention.…”

Many Philippine species are at risk of extinction because of habitat loss and degradation driven by agricultural land use and land-use change. The Philippines is one of the world’s primary banana and pineapple producers. The input-intensive style of plantation agriculture for these typically exported crops has many adverse effects on the environment. While global studies have attempted to understand the biodiversity impacts of agricultural goods, there are few studies that have investigated the Philippines specifically. In this study, Philippine policies and data are investigated to better characterize the nexus between agriculture, biodiversity, and trade. An analysis of key national policies highlights that more stringent definitions and protections for biodiversity are needed to recognize the increasing roles that agricultural production, and importantly, its global trade, have on threatened Philippine species. A geographical analysis shows that many banana and pineapple plantations in Mindanao and their surrounding agricultural impact zones overlap with ecologically important areas, such as Protected Areas and Important Bird Areas. Overlaps of recorded species occurrence are observed within the immediate zones surrounding 250 plantations for banana and pineapple in Mindanao, with 83 threatened species of Philippine fauna and tree at risk of exposure to the impacts of intensive agriculture.
