This work presents a remote sensing application to estimate the leaf area index (LAI) in two rice (Oryza sativa L.) varieties (IDIAP 52-05 and IDIAP FL 137-11), as a proxy for crop performance. In-field, homogeneous spectroradiometric measurements (350–1050 nm) were carried in two campaigns (June–November 2017 and January–March 2018), on a private...
Abstract: La mina de oro de Remance está ubicada en el pueblo de Remance, distrito de San Francisco, Provincia de Veraguas República de Panamá. La mina ha sido explotada en periodos intermitentes, la última explotación minera se dio entre los años de 1989 a 1999 por la compañía minera Remance S.A. [1], a través del proceso de cianuración. Producto...
It is an ethnobotanical research that deals with the rescue of the traditional knowledge of the Ngäbe-Buglé ethnic group and the use of native medicinal plants in the community of Santa Marta, district of Jirondai, corregimiento of Tu gwai, Ñokribo region, Comarca Ngäbe-Buglé. Ngäbe- Buglé knowledge about the healing properties of plants is being l...
The Remance gold mine, in Veraguas (central Panama), had its last mining operation in 1999, using the cyanidation process for Au separation. As a result of this activity, three waste tailings were exposed to the weather, in addition to mine dumps and the open pit mining areas. Currently the area is inhabited by peasants who develop subsistence agri...
Mining affects the environment, particularly through the persistence of accumulation of tailings materials; this is aggravated under tropical climatic conditions, which favours the release of potentially toxic elements (PTEs) bioavailable to the local flora and fauna and supposing a risk to human health. The Remance gold mine (Panamá), exploited in...
Throughout the years the human has managed to adapt to its environment by empirically applying bioclimatic design strategies, which has allowed it to survive over the years. Today these strategies have been studied and perfected. This paper shows the direct relationship between different tree configurations and the decrease in electricity consumpti...
In this article supervised classification methods for the analysis of local Panamanian rice crops using Near-Infrared (NIR) spectral signatures are assessed. Neural network (Multilayer Perceptron-MLP) and Tree based (Decision Trees-DT and Random Forest-RF) algorithms are used as regression and supervised classification of the spectral signatures by...
In the Panama context, energy consumption in the building sector is mostly related to the conditioning of indoor spaces for cooling and lighting. Different nature strategies can be mimic to strongly impact these two aspects in the building sector, such as the ones presented here. A comprehensive analysis regarding literature related to biomimicry-b...
This study deals with the estimation of the carbon associated to the Above Ground Biomass, in a permanent plot of measurement located in the Cerro Pelado Tropical Hydrology Observatory in Gamboa, Panama. The objective is to highlight the contribution made by one-hectare of this forest to the local Climate Change mitigation. We employed a relation t...
The objective of this work is to perform a prospective analysis of the wavelengths that can be used to recognize a rice crop due to its phenological status and variety. For this purpose, field measurements of spectral signature in the 350 nm -1049 nm range were employed. The rice cultivars FCA 616FL and IDIAP 54-05 were used. The study site was loc...
Panamá es un país con extensos recursos hídricos que determinan en gran medida sus actividades económicas (Espinosa, 1997). Posee de una precipitación promedio anual de 3000 mm, que alimenta alrededor de 500 ríos y 52 cuencas, que están clasificadas en vertientes del Pacífico y Atlántico (MiAmbiente A, 2011). La calidad del agua en los ríos de Pana...
This study focuses on the floristic diversity of the forest trees found at Cerro Pelado Tropical Hydrology Observatory in Gamboa, Colon, Panama. Field work for the quantitative inventory was carried out in November 2012. Data were collected by assessing the status of the forest in terms of tree species diversity and structure from one-hectare plot...
