El manejo tradicional de los sistemas productivos (SP) característico de las comunidades maya–yucatecas, como el huerto familiar y la milpa, se fundamenta en una racionalidad ecologista de diversificación del aprovechamiento de los recursos del entorno natural, permitiendo  la subsistencia y reproducción social de las comunidades por milenios. Actualmente, factores externos como los programas productivos emanados de políticas públicas, inciden en el patrimonio biocultural de los pueblos originarios, en deterioro de la sinergia entre la sociedad y la naturaleza. El presente artículo sintetiza, a través de un enfoque etnográfico cualitativo, el perfil de la comunidad de Chimay en Yucatán y la incidencia de la implementación del Programa Productivo Social Familiar del Traspatio (PPSFT) sobre el manejo tradicional del huerto, desde un enfoque de la ecología política con apoyo de la teoría de control cultural. Los hallazgos señalan que, a pesar de que los beneficiarios han adoptado ciertos elementos introducidos por el programa, existen elementos impuestos y enajenados en la implementación del PPSFT—como el formato de los talleres y la dependencia en el programa para la adquisición de semillas—que inciden sobre las prácticas, los saberes y en el tejido social de la comunidad. El estudio identifica una ambivalencia en la implementación del programa, donde  determinados elementos externos importados con el programa, deterioran ciertos valores tradicionales, favoreciendo una racionalidad economicista, que propicia una relación asistencialista y de dependencia entre los beneficiarios y el Estado. Por otro lado, el programa fomenta la apropiación y el uso de nuevas técnicas que contribuyen a maximizar la producción del huerto familiar. El panorama se presenta complejo y se hace  necesario entonces reflexionar y considerar las implicaciones de los programas socio-productivos, desde un enfoque holístico y multidisciplinario.Palabras claves: Patrimonio biocultural, huerto familiar, solar, control cultural, sistemas productivos

AbstractThe present study is aimed at the analysis of possibilities for shading southern frontage of street oriented along the E-W axis by the single row of trees, parallel to the southern elevations. The effectiveness of solar control shading was tested depending on the geometric relationships between trees and buildings. Numerical simulation analyses were conducted in Rhinoceros® program for the street located in humid continental climate in city Płock, Poland (52°32′50 “N 19°42’00 “E), for the day of the highest degree of total solar radiation in the year i.e. June 7th, during hours: 8.00a.m - 5.00 p.m. The analysis has proved that a row of 20–25 year old Sycamore Maple ‘Rotterdam’ in the street 30 m wide and 18 m high (H/W = 0.6), can provide solar protection for the southern frontage, especially when trees are located no more than 4 m away. Location of greenery within the range of 4 to 5 m from the buildings leads to a radical reduction in the possibility of shading the wall surfaces (at 5 m to 0%). Over 90% of the shading area of the ground floor façade walls was found when trees were within the distance 2 and 3 m away from the building.

The following article is intended to discuss the issues concerning the introduction of passive measures aimed at improving solar protection in multi-family buildings. A system of classifying these methods into two groups of solutions (architectural and material-building) was applied. The first group includes issues concerning facade design, the spatial features of which (such as loggias, balconies and other overhangs) can be treated as one of the solar protection methods. The authors’ own studies are presented and expressed in a sequence of formulas. The formulas enable assessment of the effectiveness of the above elements, depending on external conditions. As far as the second group is concerned, material-construction solutions for building facades and roofs are discussed. The solutions mentioned include solar-control glazing, spatial shading elements (such as venetian blinds, roller blinds), roof and façade vegetation, and the thermal mass of the building. The essence of the functioning of the analysed solutions in relation to the characteristic functional specificity of multi-family buildings is discussed. Problematic areas of application of the above methods are indicated. As shown in the study, problematic areas may include a group of utilitarian-operating, economic and aesthetic issues, in the case of which the use of passive solutions encounters limitations. In conclusion, the possibilities for alleviating these limitations are highlighted. The authors’ own solutions presented in the following paper can contribute to energy savings and may thus prove beneficial for environmental reasons, thereby serving the aims of sustainable development.
