Los catastros y registros de aguas resultan ser herramientas indispensables para garantizar la gestión integrada y desarrollo ambientalmente sustentable de las aguas subterráneas. Ellos constituyen instrumentos fundamentales ya no solo para asegurar el control y vigilancia respecto a quién o quienes se otorgan estos permisos, derechos o usos -y a quienes éstos son transmitidos-; sino también, y fundamentalmente, para determinar qué cantidad, qué calidad y qué regularidad se tiene o posee del recurso hídrico subterráneo. A pesar de estar legislados en normas provinciales, no en todas se hallan implementados. He aquí unos breves contrastes surgidos entre un análisis comparativo de legislación sobre aguas de la Provincia de Buenos Aires y Mendoza. ; Cadastres and registers of water are indispensable tools for integrated management and environmentally sustainable development of groundwater. They are fundamental instruments not only to ensure the control and surveillance in reference to who give these permissions, rights or use -and to whom these are transmitted-; but also to determine how much, what quality and what regularity has the groundwater. Despite being legislated in provincial order, not all are implemented. Here is a brief comparative analysis of legislation on waters of the province of Buenos Aires and Mendoza. ; Instituto de Cultura Jurídica (ICJ)

17 pages, 3 figures. Contributing authors: Anna Marthe Elegersma, Olafur Arnalds. ; This chapter explains how sustainable development can be translated into principles of sustainable land management. In Chapter 5 these principles will be related to European soil protection law. One of the conclusions of the SCAPE case studies described in Chapter 4 is that although principles are known, they are sometimes ignored. Maybe there are good reasons for ignoring principles and accepting soil and land degradation as a consequence. However, in most cases the choices or risks are not debated. This is partly because too frequently, decision makers do not have access to the correct information or influence. Knowing the principles is only half of the problem; the second half is requiring people to act upon them, which is a question of political will and prevailing norms. The anecdotes described in the next section show what can happen with soil conservation advice in practice. These examples are mainly from Spain and Norway, but they could have come from almost anywhere in Europe. ; Scape Project. ; Peer reviewed

[ES] La investigación se centra en el proceso de transformación de la vivienda colectiva, de interés social, en Quito. Si bien hay estudios sobre estos procesos, existen vacíos de conocimiento sobre este tema, desde un enfoque arquitectónico. El trabajo apunta a ser un pequeño aporte al conocimiento de la vivienda social en la capital del Ecuador. La construcción de vivienda de interés social ha sido, generalmente, uno de los importantes ofrecimientos de los políticos que gobiernan, en sus respectivas campañas electorales. Ya en el poder han sido muy variadas las estrategias para abordar este tema. Se pretende establecer un estudio comparativo entre las diferentes y principales propuestas de vivienda colectiva, de promoción pública, observar sus características, partiendo de las premisas del diseño, programa, tamaño (área), estructura, ubicación y contexto socio-político, indicadores que marcan una pauta objetiva para establecer parámetros de análisis y observar qué dirección está tomando la vivienda colectiva de interés social en Quito-Ecuador dentro de la arquitectura. ; [EN] The research focusses on the process of collective social housing transformation in Quito. Even though there are studies about these processes, there are gaps about this field from an architectural point of view. This work aims to be a small contribution to build on the knowledge about social housing in the capital of Ecuador. The construction of Social housing has been, generally, one of the main offerings that politicians that govern, in their correspondent electoral campaigns. When these politicians are already in power, the strategies to handle this topic have been applied in diverse fashions. It is intended to establish a comparative study among the different and main proposals for collective housing promoted by the state, observe their features, starting from their design premises, program, size (area), structure, site and socio-political context. These features mark an objective reference in order to establish analysis parameters ...

It will potentially lead to such eventualities as drought and famine, which some of the CWANA countries have already experienced. The capacity of national governments and communities to mitigate disasters will be limited in the short to medium term, rendering them still vulnerable to the adversities of climate change. Climate change is a global issue with regional implications. Many multilateral environmental agreements address these issues, and some countries of the region have ratified some such agreements (CWANA, 2009). Effects of climate change on land use refers to both how land use might be altered by climate change and what land management strategies would mitigate the negative effects of climate change (Dale, 1997). Asia is the most populous continent, population in 2002 was reported to be about 3,902 million, of which almost 61% is rural and 38.5% lives within 100 km of the coast (Duedall & Maul, 2005). Asia is divided into seven subregions, namely North Asia, Central Asia, West Asia, Tibetan Plateau, East Asia, South Asia and South-East Asia. ; Peer reviewed

Soil degradation has both indirect and direct effects on the quality of surface and ground waters. In this sense, agriculture is one of the key activities causing water quality degradation in many parts of Mediterranean systems. In the European Union, the purpose of the Water Framework Directive (European Commission, 2000) is to establish a framework for the protection of inland surface, transitional, coastal and ground waters too. A major source of surface and ground water pollution is the diffuse contamination caused by nitrates in agricultural lands. This specific water protection was regulated by the Nitrates Directive (ND, 1991/676/EC), which in Spain was developed by a Royal Decree (261/1996/BOE), and in Andalusia region by a Decree (36/2008/BOJA) for the designation of water quality vulnerability zones (22 zones) and an Order of the Regional Government of Andalusia (18.11.2008/BOJA) to establish the action programs (1 unique program) to be implemented by farmers. However, the Nitrates Directive considers that different action programs may be established for different vulnerable zones or parts of those areas. Also, these action programs must take into account scientific and technical information that are available on each particular soil and climatic conditions, such as rainfall erosivity, length of the growing season, slope, soil infiltration and soil denitrification capacity. Within this context, the agro-ecological decision support system MicroLEIS DSS (technology developed by CSIC-IRNAS and transferred to Evenor-Tech, www.evenor-tech.com) is considered a very appropriate tool to include the soil and climatic attributes for a better identification of vulnerable zones and formulation of action programs. In this paper, the MicroLEIS DSS modelling infrastructure to predict soil erosion and contamination risks (ImpelERO and Pantanal models, basically) is discussed, as a scientific approach to identify detailed vulnerable areas, and formulate site-specific management plans for sustainable water use and protection in Andalusia region. The high variability of the results from this agro-ecological land evaluation research in Water Quality Vulnerability Zones demonstrates the importance of using soil information in decision-making regarding the formulation of site-specific soil use and management strategies. ; Peer Reviewed

10 pages, 1 figure, 1 table, 60 references.-- Trabajo publicado en la Section 2: Country Reports.-- El volumen consta de 202 páginas.-- Meeting at Soil Survey and Land Research Centre Cranfield University, Silsoe, UK., que tuvo lugar del 21-22, abril, 1998. ; Meetings of European Union Heads of Soil Survey Organisations were held in 1989 and 1994 respectively. Both were followed by publication of monographs describing the state-of-the-art in each of the member countries (Hodgson 1991; Le Bas & Jamagne 1996). Limited progress has been made in Spain since then, except for a proposal for an ambitious macroproject (PNCTA), the prospects for which now seem somewhat uncertain. Readers interested in historical aspects of Spanish pedology and/or soil mapping can refer to studies by Díaz Fierros (1979 and 1997) Mudarra (1989 and 1994); Sunyer (1996), Ibáñez el al. (1991, 1997), Boixadera and Ibáñez, (1996) and Guerra, (1997). This paper describes progress in soil survey from 1994 to 1998 and provides additional information on monitoring and soil databases developed in Spain. Nevertheless, some Spanish soil databases arising from some initiatives in Pan-European programmes are not included in the discussion here due to their particular scope. The Spanish contribution to the ICP Forest programme, recently published on a CD-ROM that holds morphological, taxonomic and analytical information corresponding to 453 soil profiles, is a case in point (Montoya & López-Arias, 1998). ; Peer reviewed

12 pages, 6 figures, 3 tables, 74 references ; Soil C sequestration through changes in land use and management is one of the sustainable and long-term strategies to mitigate climate change. This research explores and quantifies the role of soil and land use as determinants of the ability of soils to store C along Mediterranean systems. Detailed studies of soil organic C (SOC) dynamics are necessary in order to identify factors determining fluctuations and intensity of changes. In this study, SOC contents from different soil and land use types have been investigated in Andalusia (Southern Spain). We have used soil information from different databases, as well as land use digital maps, climate databases and digital elevation models. The average SOC content for each soil control section (0–25, 25–50 and 50–75 cm) was determined and SOC stocks were calculated for each combination of soil and land use type, using soil and land cover maps. The total organic C stocks in soils of Andalusia is 415 Tg for the upper 75 cm, with average values ranging from 15.9 Mg C ha−1 (Solonchaks under "arable land") to 107.6 Mg C ha−1 (Fluvisols from "wetlands"). Up to 55% of SOC accumulates in the top 25 cm of soil (229.7 Tg). This research constitutes a preliminary assessment for modelling SOC stock under scenarios of land use and climate change. ; This research has been partly funded by the Ministry of Economy, Innovation and Science (Research Project 851238) and the Regional Ministry of Environment (Research Project 0501/0268) of the Andalusian Government.

A new report from Nordic Innovation shows that the Nordics have a large and untapped potential as a sustainable supplier of the raw materials the world needs to become a low-carbon emission society. The green energy transition is crucial to achieve the climate goals, and it involves a transition from non-renewables to renewables-based production, storage, transmission and use of energy. At the same time, we see an increased need for minerals that are crucial in the production of most of the technologies that are central in achieving this transition, like batteries and windmills. Today, there are not enough raw materials available to meet the basic demands needed to implement the world's climate action plan. The EU has defined certain raw materials, which are important for the economy and associated with supply risks, as critical raw materials (CRM). In addition to the fact that the Green Energy Transition is dependent on several CRMs, these raw materials are also used in existing industries and technologies, which entails fierce competition for them. We also know now that todays' extraction and the current and forecasted recycling of CRM is not able to meet the total demand of transition to a low-carbon society and to mitigate climate change. For example, International Energy Agency (IEA) forecasts that the global demand for lithium and graphite, which are among of the most important raw materials for electric car batteries, will probably be 40 times higher by 2040 if the world is to reach its climate goals. Even complete recycling of used car batteries will only cover 10 % of the demand for minerals such as copper, nickel, lithium and cobalt, according to the IEA forecast. The new report shows that the Nordics has a major potential in their bedrock to provide a secure supply of almost the full range of metals and minerals needed for the Green Energy Transition. In mineral-richness, the Nordic bedrock can be compared with the most mineral-rich areas of the world, such as Canada, the USA, Brazil and Australia. The mineral deposits represent an unexploited economic potential in our region; we already have the mining experience and technology, and knowledge about unexplored raw materials could give better utilization of and added value to existing mining operations and to our industries.
