“…6b). This indicates that the intercropped cereal most often took an advantage when growing with legumes confirming that the cereal is the most competitive species independent of cropping strategy (Vandermeer et al 1998). …”

“…These increasing concerns about environmental impacts and reduction of inputs require a transformation of current cropping systems for improved efficiency and sustainability (Cox and Atkins 1979;Jackson and Piper 1989;Vandermeer et al 1998;Griffon 2006). Organic farming is thus regarded as one prototype to enhance the sustainability of present agriculture and cereal-rich cropping systems because organic farming does not allow the use of chemicals and is also in general assumed to rely on higher crop diversity than its conventional counterpart.…”

“…Organic farming is thus regarded as one prototype to enhance the sustainability of present agriculture and cereal-rich cropping systems because organic farming does not allow the use of chemicals and is also in general assumed to rely on higher crop diversity than its conventional counterpart. Indeed, diversification of farming systems by increasing the number of cultivated species and including a larger proportion of legumes was proposed as a global response to the challenges of future agriculture (Vandermeer 1995;Vandermeer et al 1998;Altieri 1999;Griffon 2006;Malézieux et al 2009). Instead of using synthetic nitrogen fertilizers to increase farmland productivity in the short term and the overall farm production like for the Green Revolution, new systems could be designed based on symbiotic N 2 fixation by legumes.…”

“…It is defined as the simultaneous growth of two or more species in the same field for a significant period of time (Willey 1979a) but without necessarily sowing or harvesting at the same time (Vandermeer et al 1998;Malézieux et al 2009). Niggli et al (2009) describe intercropping as an eco-functional intensification practice which has been widely used to boost crop productivity (Qin et al 2013), increase the land utilization ratio (Agegnehu et al 2008) and emit significantly lower amounts of greenhouse gases compared to sole crops (e.g.…”

World population is projected to reach over nine billion by the year 2050, and ensuring food security while mitigating environmental impacts represents a major agricultural challenge. Thus, higher productivity must be reached through sustainable production by taking into account climate change, resources rarefaction like phosphorus and water, and losses of fertile lands. Enhancing crop diversity is increasingly recognized as a crucial lever for sustainable agro-ecological development. Growing legumes, a major biological nitrogen source, is also a powerful option to reduce synthetic nitrogen fertilizers use and associated fossil energy consumption. Organic farming, which does not allow the use of chemical, is also regarded as one prototype to enhance the sustainability of modern agriculture while decreasing environmental impacts. Here, we review the potential advantages of eco-functional intensification in organic farming by intercropping cereal and grain legume species sown and harvested together. Our review is based on a literature analysis reinforced with integration of an original dataset of 58 field experiments conducted since 2001 in contrasted pedo-climatic European conditions in order to generalize the findings and draw up common guidelines. The major points are that intercropping lead to: (i) higher and more stable grain yield than the mean sole crops (0.33 versus 0.27 kg m −2 ), (ii) higher cereal protein concentration than in sole crop (11.1 versus 9.8 %), (iii) higher and more stable gross margin than the mean sole crops (702 versus 577€ha −1 ) and (iv) improved use of abiotic resources according to species complementarities for light interception and use of both soil mineral nitrogen and atmospheric N 2 . Intercropping is particularly suited for low-nitrogen availability systems but further mechanistic understanding is required to propose generic crop management procedures. Also, development of this practice must be achieved with the collaboration of value chain actors such as breeders to select cultivars suited to intercropping.

“…Ejemplo de esto son los territorios de muchos pobladores campesinos de Latinoamérica, donde son comunes los paisajes que incluyen fragmentos de vegetación silvestre, barbechos de distintas edades y campos cultivados. También es común que al realizar tala selectiva de la vegetación, los campesinos manejen dentro de las parcelas agrícolas relictos del bosque, franjas de vegetación y árboles aislados que se usan como alimentos, fibras, entre otros (Vandermeer et al, 1998;Caballero & Cortés, 2001). En la Argentina, Capparelli et al (2011), postulan que los distintos "paisajes construidos", entendidos como aquellos con cambios sustanciales ligados a transformaciones en la gestión de los recursos, que forman parte de nuestra actualidad, son el resultado de la diversidad biológica, cultural y social, donde el aprendizaje y la adaptación a distintas circunstancias ambientales delinearon su estructura.…”

Summary: Grimaldi, P. A. & C. Trillo. 2018. Traditional practices and uses of "cerco" and "monte" by the criollos of San Marcos Sierras (Córdoba, Argentina). Bonplandia 27(1): 81-97.An updated contribution about the ecological knowledge of "criollos" of San Marcos Sierras about practices that originated and maintain the different landscape units is made. From semistructured interviews with key informants and participatory walks, the names of the managed units, the species, uses, and associated practices were documented. The "criollos" recognize and name 2 units of landscapes: "cerco" and "monte". A total of 57 ethnospecies were recorded, 33 for the "cerco" and 55 for the "monte". Both units share 54% of the species that receive different uses and management according to the unit where they are located. Medicinal, food, firewood and fodder are the main uses. All practices and uses were taught by the family group and belong to the traditional heritage of the farmers. Increased ethno-ecological and ecological analyzes are necessary to understand the changes in the floristic composition of the forest and / or the abundance of some woody species. Se realiza un aporte actualizado del conocimiento ecológico de los pobladores criollos de San Marcos Sierras sobre prácticas que originaron y mantienen las diferentes unidades de paisaje. A partir de entrevistas semi-estructuradas a informantes clave y caminatas participativas se documentaron los nombres de las unidades manejadas, las especies presentes, sus usos y las prácticas asociadas. Los pobladores reconocen y nombran 2 unidades de paisaje, "cerco" y "monte". Se registró un total de 57 etnoespecies, 33 citadas para el "cerco" y 55 para el "monte". Ambas unidades comparten el 54% de las especies que reciben usos y manejos diferentes según la unidad donde se encuentran. Los usos principales que satisfacen las unidades son medicinal, alimentario, leña y forraje. Todas las prácticas y usos fueron enseñadas por el grupo familiar y pertenecen al patrimonio tradicional de los ganaderos. Se hacen necesarios mayores análisis etnoecológicos y ecológicos para comprender las modificaciones en la composición florística del bosque y/o la abundancia de algunas especies leñosas.Palabras clave: Criollos, etnoecología, prácticas tradicionales, unidades de paisaje.1 Proyecto D-Tec 0016/13.
