A list of freshwater fishes inhabiting lakes, reservoirs and rivers of Armenia is presented which include 39 species and subspecies belonging to 5 orders, 9 families and 29 genera. A brief description of the ecology, distribution and present status (introductions, threats, commercial value) of these fishes is given.

The most appropriate way to measure the social benefits of conserving built cultural heritage sites is to ask the beneficiaries of conservation interventions how much they would be willing to pay for them. We use contingent valuation - a survey-based approach that elicits willingness to pay (WTP) directly from individuals - to estimate the benefits of a nationwide conservation of built cultural heritage sites in Armenia. The survey was administered to Armenian nationals living in Armenia, and obtained extensive information about the respondents' perceptions of the current state of conservation of monuments in Armenia, described the current situation, presented a hypothetical conservation program, elicited WTP for it, and queried individuals about what they thought would happen to monument sites in the absence of the government conservation program. We posit that respondents combined the information about the fate of monuments provided by the questionnaire with their prior beliefs, and that WTP for the good, or program, is likely to be affected by these updated beliefs. We propose a Bayesian updating model of prior beliefs, and empirically implement it with the data from our survey. We found that uncertainty about what would happen to monuments in the absence of the program results in lower WTP amounts. © 2008 Pion Ltd and its Licensors.

The forest has a crucial ecological role and the continuous forest loss can cause colossal effects on the environment. As Armenia is one of the low forest covered countries in the world, this problem is more critical. Continuous forest disturbances mainly caused by illegal logging started from the early 1990s had a huge damage on the forest ecosystem by decreasing the forest productivity and making more areas vulnerable to erosion. Another aspect of the Armenian forest is the lack of continuous monitoring and absence of accurate estimation of the level of cuts in some years. In order to have insight about the forest and the disturbances in the long period of time we used Landsat TM/ETM + images. Google Earth Engine JavaScript API was used, which is an online tool enabling the access and analysis of a great amount of satellite imagery. To overcome the data availability problem caused by the gap in the Landsat series in 1988- 1998, extensive cloud cover in the study area and the missing scan lines, we used pixel based compositing for the temporal window of leaf on vegetation (June-late September). Subsequently, pixel based linear regression analyses were performed. Vegetation indices derived from the 10 biannual composites for the years 1984-2014 were used for trend analysis. In order to derive the disturbances only in forests, forest cover layer was aggregated and the original composites were masked. It has been found, that around 23% of forests were disturbed during the study period.

A raíz del pavoroso terremoto que tuvo lugar en el Eje Cafetero colombiano en 1999, que causógrandes pérdidas humanas y una gran destrucción, sobre todo del inventario inmobiliario, hubo ungran movimiento nacional de solidaridad tanto estatal como privado para socorrer las víctimas. Elprincipal rubro fue de recursos en la forma de subsidios a los afectados para que compraran nuevasviviendas, pero no se tomaron precauciones con respecto al mercado de tierras, a pesar de que lalegislación tiene valiosos instrumentos de gestión del suelo. En este estudio se hace una estimacióndel monto de estos subsidios que en realidad fueron apropiados por los propietarios de los terrenos,en la forma de elevación de precios del suelo y no por los damnificados. El caso es interesante porquelo observado tal vez pueda aplicarse al sistema general de subsidios de vivienda que constituyeel eje central de la política gubernamental

Este trabajo recoge el resultado de un proceso investigativo que da cuenta de los imaginarios urbanos generados en los ciudadanos a raíz del terremoto de Armenia, Quindío, en el año 1999. La investigación centra su atención en las formas mediante las cuales se reconfiguraron las estructuras sociales y culturales de los ciudadanos, cómo esto transformó el curso de la ciudad y trazó nuevas territorialidades, hasta el punto de convertir el hecho en un referente que permitió pensar la ciudad a partir de un antes y un después del sismo.
