India: para alimentar satisfactoriamente a 1.2 millones de personas, será necesaria una segunda green revolution. Y, para nosotros, y para el mundo, será interesante observar como India soluciona ese problema
(2008-05)
período agrícola 2007-2008, la producción
mundial de cereales está complicada. Nada
nuevo. Ha estado deficitaria toda la década1.
La producción global para el 2008 se estima en
2102.6 millones de toneladas (m.t.); 4.6% más
que el período anterior...
ningún estudio serio demuestra que el “efecto invernadero” ya esté afectando en las producciones agrícolas. Quinto: No echarle la culpa al empedrado sino remediar la propia cojera Así queda demostrado que la supuesta crisis alimentaría se reduce...

Biodiversidad en viñedos : el caso del Valle de Apalta
(Universidad de Chile, 2022)
los paisajes agrícolas y rurales. La homogeneidad de los cultivos resultante de esta intensificación es un signo de la poca diversidad de especies presentes. El caso de la viticultura y la producción de la vid es parte de esta agroindustria, donde por...
Análisis la implementación de invernaderos calefaccionados con geotermia en Chile y su comparación con países bajos
(Universidad de Chile, 2022)
El presente estudio de caso corresponde a una recopilación y análisis de información actual pertinente en materia de uso de energía geotermal para la producción en invernaderos en Chile. A raíz de las nuevas dinámicas territoriales que se han ido...
This case study corresponds to a compilation and analysis of relevant current information on the use of geothermal energy for production in greenhouses in Chile. As a result of the new territorial dynamics that have been configured with both economic and population growth, new food needs have arisen throughout the country. The use of heat from various geothermal sources is essential for the economic development of the territories in the south of the country and the opportunity for exploitation grows based on the comparative advantages with respect to the existing natural resources. However, the main disadvantage has to do with the limited technological development for the exploitation of these resources. Between Chile and the Netherlands, there is an important gap both public and private, in the development of geothermal energy for agricultural purposes. The main definitions of geothermal energy and its scope in terms of the main heating systems for greenhouses both in the Netherlands and in Chile were addressed. The methodology used sought to make a diagnosis and evaluate the possibility of implementing agricultural projects in the study area through the bibliographic compilation and the field visit to interview the main actors and protagonists who today experiment with said technology in success cases. The analysis of the information allowed establishing a panorama for decision-making, both private and government entities for the promotion of initiatives in this area. During the discussion, both experiences were compared, both in Chile and in the Netherlands, to elucidate the existing gap and the strategies that Chile could address. Finally, an analysis was carried out to conclude the comparative advantages, strengths and opportunities that Chile has in order to set a roadmap towards the real implementation of said policies as a trend towards a new way of producing....

Impacto de la minería de áridos sobre el paisaje cultural agrícola, estudio de caso: Estación Experimental Germán Greve Silva, Rinconada de Maipú
(Universidad de Chile, 2014)
Originalmente en la Estación Experimental (EE) Germán Greve Silva de la Universidad de Chile, existía un paisaje natural, sin intervención, que evolucionó a causa del hombre hasta un paisaje cultural agrícola, a través de un proceso de...
Originally in the Germán Greve Silva Experimental Station (ES) of the Universidad de Chile existed a natural landscape, without intervention, evolved for man until an agricultural landscape, through an artificialization process of landscape. Parallel to the agricultural activity, introduced in this landscape the aggregates production, is an industrial activity and performed on agricultural soils in the SE, competing both activities for the same soil. The cultural landscape according Gastó (2012), considered three fundamental elements for its realization: Territory, Parties, Technology and Institutions and Regulations. Impacts that this extractive activity occurs on the agricultural landscape in the ES are the objective of this work. It analyzed, for each of the landscape components used by Gastó (2012). This analysis was conducted in two spatial scales (local and regional) and two timescale (before and after aggregates production). An economic analysis was also performed of the Soil Without Production (SWP) of the agricultural land (t1) and Exploited Soil Not Rehabilited (SENR) of the agricultural land whit aggregates production (t2) for a corn crop, comparing the net actual values (VNA) of both situations, to estimate the economic loss in the property for the farmer in a corn crop. According to research, with the arrival of mining joined parties and weighing technology to property not previously existed and modified the agricultural landscape, as miners and tuckers. Chilean law there is many institutions which have power about aggregates production. However, the key situation and allowing this conflict in facing two productive activities complement opposite is the legal vacuum that exists. This legal vacuum whereby extracted this highly requested material in the construction industry is subject to the mining law, does not consider the aggregates as minerals and grantable materials, but will continue extracting with the objective of explore and exploit other minerals considered themselves industrial and grantable for the mining law. Respect the economic analysis, a difference was obtained in yield of a 38% in the crop, resulting for a SWP and SENR a VNA of 1.626.914 y -1.848.143 respectively. In conclusion, the aggregates production, in the ES Germán Greve Silva property, more modifies the territory and also, performs the extractive work illegally....
