The decline in maize production may mainly be attributed to improper or excessive use of fertilizers, leading to significant soil nutrient losses. The integrated use of crop residues and synthetic fertilizers is more profitable and beneficial in meeting crop nutritional needs, ensuring long-term production and environmental protection. Advances in...

Winemaking in Chile is a long tradition that is recognised around the world. It is especially important in the Maule region where more than 40% of the total wine in the country is produced. However, there is a lack of studies related to soil erosion in vineyards in Chile, especially considering the extreme rainfall events that occur in the country....

Agricultural lands are sources and sinks of greenhouse gases (GHGs). The identification of the main drivers affecting GHGs is crucial for planning sustainable agronomic practices and mitigating global warming potential. The main aim of this research was to evaluate the impact of environmental drivers (soil temperature and water-filled pore space, W...

The intensification of specific land management operations (tillage, herbicide, etc.) is increasing land degradation and contributing to ecosystem pollution. Mulches can be a sustainable tool to counter these processes. This is particularly relevant for rural areas in low-income countries where agriculture is a vital sector. In this research, the e...

Accurate soil thermal conductivity (λ) measurements are needed in experimental agri-environmental research. This study design and build of new heat-pulse probe (HPP) based on transient state technology to measure λ. The HPP consists of three main components: an electronic control system, a measurement chamber, and sample rings. The performance of t...

A refined investigation of new trends in urban analysis assuming a sustainable design of Areas of Public Space and Meeting (APSM) is a fundamental response to the challenges of inclusive and efficient cities. Even though the APSM are districts regarded as urban structuring systems, there is a lack of territorial planning instruments and conceptual...

Agricultural activity is the major anthropogenic source of nitrous oxide (N 2 O) emissions from terrestrial ecosystems. Conservation agriculture including crop residue management can play a key role in enhancing soil resilience to climate change and mitigating N 2 O emissions. We investigated the effects of crop residue rates, including 100 % (R 10...

Farmland shelterbelt system (FSS) in oasis desert ecotones can effectively improve ecosystem services, especially in fragile agricultural areas. However, the spatial-temporal heterogeneity of its ecological effects still needs further clarity, because the interactions are complex and multiple. Understanding this allows us to know the key practical...

The design and application of multiple tools to spatially assess soil properties are key to efficient land management plans. While soil micronutrients are paramount soil properties for multiple purposes, collecting a representative number of samples is time-consuming and expensive. The main aim of this research was to evaluate different scenarios i...

To evaluate the response of saffron to animal manure, and biological and chemical fertilizer in an arid climate, an experiment was performed as split plots based on a randomized complete blocks design with three replications during three consecutive crop growth seasons (2015–2018) at the Research Farm of University of Gonabad, Iran. The experimenta...

Appropriate management of crop residue plays a key role in mitigating greenhouse gas emissions. However, it has been inadequately implemented in general agricultural management practices. In a field investigation using static chambers, we evaluated the effects of crop residue at three different rates - 100% (R100), 50% (R50), and residue removal (R...

This study explores the possibility to decipher if changes in the total area of a karst wetland due to land use, economy and population variations over a long‐term period (35 years) can affect microclimate changes (1958‐2019). To achieve this goal, we focused on Huangcaozhou, a national karst wetland park located in China. Our results showed that f...

El manejo del suelo es un tema clave para la correcta conservación del territorio, que permite contribuir al cuidado del medioambiente y garantizar la seguridad alimentaria. Su gestión poco sostenible, debido al uso de herbicidas, el laboreo o la intensificación de las plantaciones, dificulta la compleción de dichas metas. En la costa meridional de...

Soil loss from root crops is an increasingly significant problem studied for some species, such as potatoes, sugar beets, carrots, celery, and onions. It reduces soil fertility and, subsequently, soil productivity. For leek and groundnut, however, there is little information to date. More research on this topic could help farmers reduce the process...

This research examines the level of intellectual production of the human capital in the creative cities (as declared by UNESCO) of Colombia and Latin America. The methodological framework is based on the review of academic production in Web of Science in the period 2009 - 2019. In Colombian cities territorial development should create linkages betw...

Resumen La comprensión de las tensiones sociales y políticas actuales genera un renovado interés en el estudio de los procesos de construcción identitaria. Sin embargo, el concepto de “identidad”, pese a su gran presencia en los discursos públicos, sigue siendo afectado por una profunda ambigüedad definitoria que limita su utilidad analítica y difi...

This study is the first analysis of the influence of the design of the logos of the National and Natural Parks of Spain on social attitudes toward these protected areas (PAs). The effect of certain elements in the logo of a PA on its attractiveness and on support for its conservation was explored through a questionnaire survey of groups of universi...

This study analyzes the phenomenon of “localized transnationalism.” The concept refers to the prolonged and intense maintenance of cross-border connections by migrants whose capacity for geographic mobility is very limited. The study is based on ethnographic research which focused on Senegalese migrants in southern Spain. The results contribute to...

The coastal strip of the western peri-urban area of Barranquilla in the Atlántico Department (Colombia) is experiencing changes in human-environment interactions through infrastructure, residential, and tourism projects in a vulnerable landscape. In the hilly area, fragments of biodiverse tropical dry forest still exist in various states of conserv...

En el contexto geográfico iberoamericano, el análisis de la fauna silvestre se ha insertado tradicionalmente en el campo de la zoogeografía, mientras que el estudio de la ganadería y de la fauna cinegética se ha abordado desde la geografía rural y del turismo y, en menor medida, desde la geografía del paisaje. En la geografía anglosajona, sin embar...

La presente investigación muestra cómo el mercado laboral puede marcar profundamente las maneras en las que la religión es comprendida y practicada en el contexto migratorio. En la actualidad existen evidencias empíricas sólidas que indican que en diversos países de destino la población migrante, con frecuencia, se ve sobrerrepresentada en nichos l...

Barranquilla is known as a dynamically growing city in the Colombian Caribbean. Urbanisation induces land use and land cover (LULC) changes in the city and its hinterland affecting the region's climate and biodiversity. This paper aims to identify the trends of land use and land cover changes in the hinterland of Barranquilla corresponding to 13 mu...

Since 1971 the programme Man and the Biosphere (MaB) of UNESCO has been dedicated to promoting Protected Areas in which conservation of nature is closely linked to territorial development that is beneficial to local communities. In Spain the first area declared as a Biosphere Reserve was Sierra de Grazalema (1977). The history of the management of...

Changes in the ways of living in the Sierra Nevada region, its new functions as well as the effects of sectoral policies, such as forestry or protection measures, have led to profound changes in the planning model and the landscape. This paper, based on the analysis of the aerial photographs of 1956 and 2006, analyses landscape evolution in order t...
