“…The decrease of these areas represents a problem for the loss of landscape, social and cultural value, and in terms of ecological connectivity and biodiversity [6,45,[50][51][52]. Agricultural areas in which nonintensive activities are carried out represent a key component in the ecological connectivity of the landscape [6,50,53,54]. The 28-year loss of a vast surface of this land type has certainly undermined the integrity of the MCN's ecological network, reducing the resilience of habitats and increasing their fragility [6,29,45,55].…”

Nowadays, anthropic pressures are continuously transforming the landscape mosaic, leading to issues related to habitat fragmentation and the loss of ecosystem functions. In this study, a landscape-change analysis over the 1990–2018 timeframe of the case study area of Metropolitan City of Naples (MCN) (southern Italy) was performed to evaluate trends, causes, and results of the landscape transformations. We preliminary performed a spatial–temporal fragmentation-expansion analysis in the MCN through the landscape expansion index (LEI), and subsequently determined the impacts on the eco-mosaic. The multitemporal analysis (1990–2018) highlighted an urban expansion in the MCN. The LEI analysis depicted a dual tendency in the increased fragmenting of the MCN’s eco-mosaic. The urban landscape has compacted in the hollow areas, and in the meantime there has been a sprawling expansion of the urban fabric. The most impacted land-use category was “Agricultural areas”, of which 57.42 km2 have been lost in 28 years, with negative impacts on ecological connectivity. Finally, we investigated the relationship between the increase and type of landscape fragmentation and the demographic flows over time. We found that the areas affected by demographic growth were the same ones characterized by an edge expansion of the urban patterns. Conversely, where there has been a demographic decrease, an infilling behavior of urban fabric has been noted. This study highlights a possible correlation between the expansion type of the urban fabric and the demographic flows in a region as a main driver. The outcome of 30-year transformations is the actual ecological network in which Core Areas, Buffer Zones, and Primary Connections covered 35.3%, 11.1%, and 39.6%, respectively, of the total surface of the MCN, covering an overall area of 1008.4 km2.

“…Con esos antecedentes, la producción de alimentos debe planificarse teniendo en cuenta el equilibrio entre las interacciones de los ciclos biogeoquímicos y energéticos de las explotaciones agropecuarias dentro de un marco geográfico biorregional. Para tal fin, se debe avanzar hacia prácticas agroecológicas que superen los impactos del monocultivo agroindustrial (Altieri et al, 2015), pero ellas deben ser analizadas desde una perspectiva multicriterio para evaluar su viabilidad y sus consecuencias (Padró et al, 2020).…”

La presente Tribuna reflexiona sobre los efectos de la alteración de los ecosistemas y la biodiversidad en el incremento de problemáticas sanitarias y ambientales relacionadas, según evidencia la crisis mundial por la COVID-19. La generalización de modelos urbanos densamente poblados y en creciente expansión ha propiciado la contaminación ambiental, así como el incremento del riesgo frente a enfermedades e inundaciones. Igualmente, la industrialización de la cadena alimenticia ha favorecido la aparición de enfermedades como diabetes, así como de patógenos que provocan enfermedades infecciosas. Con la globalización, estas últimas se han transmitido rápidamente desde zonas rurales a poblaciones urbanas, en una acelerada expansión. Consecuentemente, se llama a una redefinición de las relaciones campo-ciudad en clave biorregional, y desde una aproximación socio-ecológica, para mantener y restaurar la estructura ecológica de soporte. Con ello se podría fortalecer la resiliencia territorial, a través de una configuración modular, flexible y policéntrica.

Objective: To analyze a coffee agroecosystem undergoing an agroecological transition —considered as an alternative for the efficient use and the conservation of resources— through an agroecological association design with three legumes and one cucurbit in coffee cultivation. Design/Methodology/Approach: Collection and identification of genetic resources found in the agroecosystem; agroecological association design with three legumes and one cucurbit in a coffee crop; zig-zag soil sampling for physical, chemical, and biological analyses; data analysis using JASP software version 0.16.2. Results: We identified 42 weed species with various uses within the coffee agroecosystem, as well as the criteria for the association of species according to use. The soil analysis showed a significant correlation between micronutrients and nitrogen-fixing bacteria. The boron variable also influences the growth of such bacteria. Study Limitations/Implications: The results apply to the agroecological model in transition presented. Findings/Conclusions: Agroecological transition in coffee agroecosystems is slow but contributes to improving soil conditions. It also allows for the reappearance of usable weed species. There is a significant correlation between boron and the development of nitrogen-fixing bacteria. Likewise, the physical properties of soil have a direct impact on the growth of such bacteria
