Impairing the largest and most productive forest on our planet: how do human activities impact phytoplankton?
2012
This article summarizes the outcomes of the 16th Workshop of the International Association for Phytoplankton Taxonomy and Ecology. Four major issues dealing with the impact exerted by human activities on phytoplankton were addressed in the articles of this special volume: climate change and its impacts on phytoplankton, the role of land use in shaping composition and diversity of phytoplankton, the importance of autecological studies to fully understand how phytoplankton is impacted by stressors and the role of ecological classification to evaluate community changes due to the different impacts. Case studies from different types of aquatic environments (rivers, deep and shallow lakes, reser…
Aspects of phosphorus transfer from soils in Europe
2008
Imbalanced nutrient management has caused soil phosphorus (P) to become an environmental rather an agronomic problem in more economically developed countries. This subject has been the topic of numerous journal special issues, conferences, and reviews but we consider yet another review of this subject is necessary with the main target of providing a point of view on non-point transfer from soils and control strategies for an improved environmental management of P. This review considers the causes of the excessive P transfer from soil to surface water in Europe and the scientific knowledge necessary to develop control strategies. There has been an increasing trend towards the P-research inte…
Urban development and evolution of Valencian seaside destinations
2018
Mass tourism activity entails resource consumption and land uses usually difficult to be managed in a satisfactory way by urban planners. In practice, urbanism becomes a key tool in the des...
The Evaluation Of The Influence Of Land Surface Temperature In Energy Balance Estimated By S-Sebi Model
2020
Evapotranspiration (ET) is one of the least understood components of the hydrological cycle. Its application is varied, from agricultural, ecological and hydrological monitoring, to control of the evolution of climate change. The goal of this work was to analyze the influence that uncertainties in the estimate of Land Surface Temperature (LST) can cause on ET estimates by S-SEBI model in Pampa Biome area. The results indicate that the daily evapotranspiration is higher when the pixel LST is lower, which also shows the influence of land use on the variability of ET. They also demonstrated the importance of LST's accuracy in the selection of the driest and wettest pixels in applying S-SEBI mo…
Assessment of bioenergy potential in Sicily: a GIS-based support methodology
2008
Abstract A Geographical Information System (GIS) supported methodology has been developed in order to assess the technical and economic potential of biomass exploitation for energy production in Sicily. The methodology was based on the use of agricultural, economic, climatic, and infrastructural data in a GIS. Data about land use, transportation facilities, urban cartography, regional territorial planning, terrain digital model, lithology, climatic types, and civil and industrial users have been stored in the GIS to define potential areas for gathering the residues coming from the pruning of olive groves, vineyards, and other agricultural crops, and to assess biomass available for energy cu…
The European Union can afford greater ambition in the conservation of its threatened plants
2021
The importance of Natura 2000 network for the conservation of natural habitats, wild flora and fauna at European level is undeniable. However, it may not have reached its full potential since the loss of biodiversity continues to increase year on year. Further on, a third of the plant species listed in the Habitats Directive to guide the declaration of European Union Natura 2000 network of protected areas is not threatened and there is broad agreement on the need to review and update the species list. Here, the effectiveness of Natura 2000 in the conservation of Spanish bryophytes and vascular plants included in the Habitats Directive Annex II is analysed and compared with the one offered t…
Hydrological consequences of natural rubber plantations in Southeast Asia
2020
Since the turn of the century, rubber plantations have been expanding their footprint across Southeast Asia in response to an increasing global demand for rubber products. Between 2000 and 2014, the area cultivated with rubber more than doubled. It is not clear how this major change in the agricultural landscape of Southeast Asia, the main area of rubber production in the world, is affecting land‐use patterns and water resources in the region. Here we use maps of rubber plantations and other croplands in conjunction with a hydrological model and remote sensing analyses to assess land‐use patterns and water resources affected by natural rubber plantations. Results show water requirements of …
The Traditional Mediterranean Polycultural Landscape as Cultural Heritage: Its Origin and Historical Importance, Its Agro-Silvo-Pastoral Complexity a…
2016
Today, the Mediterranean is characterized by landscape patterns whose compositions result from countless, long and complex cultural and historical processes. However, the pressure on these landscapes and their rapid transformation into more modern forms call out for a better knowledge of the more complex forms of traditional land use and relative landscapes. In this context, an identification and clarification of the role of such mixed and complex forms of agro-forestry systems and landscapes, named “giardino Mediterraneo” (“Mediterranean garden”) is necessary. This term is often applied to and associated with numerous different agricultural and agro-forestry systems as well as to numerous …
Automatic detection and agronomic characterization of olive groves using high-resolution imagery and LIDAR data
2014
The Common Agricultural Policy of the European Union grants subsidies for olive production. Areas of intensified olive farming will be of major importance for the increasing demand for oil production of the next decades, and countries with a high ratio of intensively and super-intensively managed olive groves will be more competitive than others, since they are able to reduce production costs. It can be estimated that about 25-40% of the Sicilian oliviculture must be defined as “marginal”. Modern olive cultivation systems, which permit the mechanization of pruning and harvest operations, are limited. Agronomists, landscape planners, policy decision-makers and other professionals have a grow…
REPRESENTATIONS OF BOUNDARIES IN THE CONTEXT OF PRIVATE AND PUBLIC RELATIONSHIPS: LATVIAN EXAMPLE
2012
In social practice boundaries often have been perceived and used as a tool of structuring of the space. Spatial structures appear as representations of different activities and patterns as public and private relationships. Formal regulations, public attitudes forming on the basis of values system, acceptance and rejection of norms create different forms of individual adaptation cases which are representing in planning practise and landscape as a contradictory public and private relationships. Baltic coastal areas, Riga agglomeration, settlements structure, local suburban land transformation processes are some of the areas have been explored. What are public and private in using of space, w…
