Resident perceptions of natural resources between cities and across scales in the Pacific Northwest

As the global population becomes increasingly urban, research is needed to explore how local culture, land use, and policy will influence urban natural resource management. We used a broad-scale comparative approach and survey of residents within the Portland (Oregon)-Vancouver (Washington) metropolitan areas, USA, two states with similar geographical and ecological characteristics, but different approaches to land-use planning, to explore resident perceptions about natural resources at three scales of analysis: property level (“at or near my house”), neighborhood (“within a 20-minute walk from my house”), and metro level (“across the metro area”). At the metro-level scale, nonmetric multidimensional scaling revealed that the two cities were quite similar. However, affinity for particular landscape characteristics existed within each city with the greatest difference generally at the property-level scale. Portland respondents expressed affinity for large mature trees, tree-lined streets, public transportation, and proximity to stores and services. Vancouver respondents expressed affinity for plentiful accessible parking. We suggest three explanations that likely are not mutually exclusive. First, respondents are segmented based on preferences for particular amenities, such as convenience versus commuter needs. Second, historical land-use and tax policy legacies may influence individual decisions. Third, more environmentally attuned worldviews may influence an individual’s desire to produce environmentally friendly outcomes. Our findings highlight the importance of acknowledging variations in residents’ affinities for landscape characteristics across different scales and locations because these differences may influence future land-use policies about urban natural resources.

Fauna of plant-parasitic nematodes in natural and cultivated areas of the Amazon forest, Mato Grosso State, Brazil

The aim of this work was to study the diversity of the fauna of plant-parasitic nematodes in preserved areas of the Amazon forest, Mato Grosso state (MT), and to assess the effect of agricultural land use on plant-parasitic nematode communities. Soil and root samples were collected in each location in the late spring during the rainy season of 2005, in two areas of primary vegetation in Nova Maringa (Northwest) and Guaranta do Norte (North) and two adjacent areas planted with teak trees (Tectona grandis) and pasture (Brachiaria brizantha). Four-teen taxa of plant-parasitic nematodes were identified at species level: Discocriconemella degrissei, D. limitanea, Dolichodorus minor, Helicotylenchus erythrinae, H. pseudorobustus, Meloidogyne exigua, M javanica, Mesocriconema ornata, Paratrichodorus minor, Pratylenchus loosi, P zeae, Rotylenchus caudaphasmidius, Xiphinema ensiculiferum and X luci (for the first report of this in Brazil) and five at genus level (Atalodera sp., Hemicriconemoides sp., Meloidogyne sp., Paratylenchus sp., and Trophotylenchulus sp). These taxa, mainly those from primary vegetation, belong to families with different parasitic behavior, probably due to great plant diversity in the Amazon forest. Comparison between the two preserved areas revealed low index of similarity, as a consequence of the endemic flora in the Amazon forest, and no similarity was observed between preserved native vegetation and adjacent cultivated areas, demonstrating the high influence of agricultural activity on the plant-parasitic nematode communities. There is evidence of recent introduction of plant-parasitic nematodes in these cultivated areas; therefore measures should be taken to prevent the loss of economic sustainability in Amazonian soils. Keywords: abundance, Amazonia, diversity, Brachiaria brizantha, plant-parasitic nematode fauna, Tectona grandis.

Economic rents, institutions and growth: International aid and natural resources: A comparative analysis

A Work Project, presented as part of the requirements for the Award of a Masters Degree in Economics from the NOVA – School of Business and Economics

Sustentabilidad del monocultivo de soja y otras alternativas agrícolas, en relación a los recursos suelo y agua, en la Región Centro-Norte de Córdoba. Sustainability of soybean monoculture and another agricultural alternatives, in relation to soil and water natural resources, in the north-central area of Cordoba (Argentina).

En este proyecto se pretende demostrar que existen alternativas sustentables al monocultivo de soja y económicamente factibles si se consideran los costos ambientales.Se cumplirán los siguientes objetivos específicos:- Caracterizar la sensibilidad de indicadores de calidad del suelo: infiltración, densidad aparente, penetrometría, C orgánico, fracciones de la MO y un índice químico de disponibilidad de N. - Medir escurrimiento y erosión en dos microcuencas con manejos contrastantes donde existe instrumental instalado y registros desde hace mas de 10 años.- Establecer rangos para las situaciones encontradas en los suelos representativos de la región.- Integrar los parámetros considerados en un sistema de diagnóstico de calidad/salud del suelo, para las condiciones de la región. - Aplicar el sistema de Calidad/salud del suelo para situaciones con monocultivo de soja y otras alternativas.- Calibrar y aplicar el modelo de simulación de la materia orgánica AMG, al monocultivo de soja y otras alternativas, a distintas escalas temporales y espaciales.- Estimar los costos ambientales de monocultivo a partir de los datos obtenidos.- Extrapolar los resultados del monocultivo y las otras alternativas a los suelos característicos, para estimar la sustentabilidad de los suelos en el centro-norte de la provincia de Córdoba.Se trabajará en dos áreas piloto en campos de productores, con y sin erosión hídrica. Se evaluarán parámetros indicadores del estado de los suelos, se los integrará en un sistema, se evaluarán los suelos con situaciones de monocultivo de soja y manejos contrastantes y se los correlacionará con su historial de intervención antrópica. Se brindará una herramienta apta para el ordenamiento territorial.
