    Efecto de la retención de agua y las propiedad físicas del suelo, por la aplicación de tres tipos de coberturas, en el cultivo de lechuga Lactuca sativa, regado mediante goteo
    (2016-04-26) León Pacheco, Eugenia Esperanza; Belesaca Morocho, Iván Robalino
    Water consumption of treatment with pine needles introduced more effective water consumption. Reducing temperature fluctuations soil efficiency of three padded shown. The bulk density of the soil in the three toppers expressed above control values. While the pH and conductivity no differences were determined. The production of lettuce (Lactuca sativa) with pine needles was 0.91kg / plant, polyethylene with 0.87kg / plant, witness with 0.86 kg / plant and rice husks with 0.77 kg / plant. The mean diameters of the bud and stem diameters no significant differences

    Influencia de la estructura agraria en la economía campesina agroecológica y no agroecológica en estudios de caso en las comunidades indígenas Cañaris de Shiña y Chunazana, cantón Nabón
    (2018) Santacruz Salazar, Lina Jeanneth; Minga Ochoa, Nancy Marlene
    Agrarian structure conditions the development of small-scale peasant agriculture, as well as its breakdown by linking it in a progressive manner to the market economy and agro-industry. This study evaluates how agroecology contributes to halting the advance of the impacts of capital on the familiar economy, determining for this the influence of the agrarian structure on peasant economies with an agro-ecological and non-agro-ecological productive matrix. The research was conducted in indigenous communities of Nabón canton, Azuay province, based on nine study cases focused on three types of Family Peasant Agriculture: consolidated agro-ecological, in transition to agroecology, and conventional. The Methodology of Economic-Ecological Evaluation of Agroecosystems (Petersen et al., 2017) was used and adapted to measure the levels of autonomy and sustainability of agroecosystems. In addition, a review of secondary sources and semi-structured interviews with key actors were also used. The results suggest that access to land is the determining factor that limits economic reproduction in all types of Family Peasant Agriculture, subjecting them to a progressive process of minifundization, despite the fact that these are located in indigenous territories. Other factors such as access to water, direct markets, and technified irrigation affect differently the types of Family Peasant Agriculture. Despite these limitations, the cases of agro-ecological and transitional agriculture show higher levels of productive autonomy and sustainability with respect to conventional agriculture. Those factors are determinant to avoid - prevent the breakdown of this type of economies
