Don plantations across an age sequence in the Pampean region of Argentina. Area of study: Plantations were ... -
Huertas familiares en el contexto de la agricultura pampeana: Caracterización de la actividad hortícola y percepción sobre los invertebrados presentes en las huertas del partido de San Antonio de Areco, Buenos Aires, Argentina = Family orchards in the context of Pampas agriculture: Characterization of horticultural activity and perception of the invertebrates present in the orchards of the district of San Antonio de Areco, Buenos Aires, Argentina
(Sociedad Entomológica Argentina, 2024-03)In recent years, horticulture in the northern region of the Buenos Aires province, Argentina, has increased. Accurate information on this activity is a prerequisite to address potential phytosanitary problems that farmers ... -
Human-nature interaction approached from a bibliometric analysis of Malthus and Boserup
(Ediciones INTA, 2024-05)The theoretical framework of Complex Adaptive Systems allows modeling human-environment interactions that are constantly evolving and have implications for sustainability. The aim of this paper is to identify which approach, ... -
