(FLACSO Ecuador, 2018)En el presente artículo se reconstruyen históricamente los territorios periurbanos de Córdoba, con foco en los destinados a la producción hortícola para suministro de la ciudad, sistematizando investigaciones y ... -
Geoscience and remote sensing on horticulture as support for management and planning
(Open Access Pub, 2019)The importance of horticulture around the large cities, called green belt (GB), or proximity food production area is related to its contribution to the provision of food as well as its role on social, cultural and ecological ... -
Mapping and characterizing the Green Belt of Córdoba: land dynamics and the urban-rural transformation process
(Open Access Pub, 2019)In Córdoba, Argentina, the peri-urban horticulture is in conflict with industrial agriculture and urban development. This problem is partly due to urban expansion to rural areas occurred in the last years and to monoculture ... -
The use of nutritional blocks as a tool for grazing management in extensive sheep husbandry
(Asociación Argentina de Ecología, 2021-09-05)The improvement in grazing spatial distribution is an important goal for the efficient and sustainable management of rangelands. However, extensive livestock systems such as the Patagonian rangelands generally fails due ... -
Importance of human capital, field knowledge and experience to improve pest locust management
(2021-07-27)BACKGROUND: A poorly organised risk management system may dysfunction when used. The consequences can be dramatic for those supposed to be protected. Since the 1960s, preventive control strategies, with field officers as ... -
