  • Flood processes and morphological changes in aggradational ephemeral
           rivers. Reconstruction of the October 1957 flood in the Rambla Castellarda
           (Spain)

    • Authors: Carles Sanchis Ibor, José Luis Iranzo Quevedo, Francisca Segura-Beltran
      Pages: 3 - 21
      Abstract: During the latter half of the twentieth century, Mediterranean ephemeral rivers underwent a profound metamorphosis. Fluvial adjustment processes narrowed the channels, simplified their planform pattern and notably reduced sediment availability. Today, this makes it extremely difficult to analyse the behaviour of this type of river in former aggradational contexts, such as those seen at the middle part of the twentieth century. For this reason, this paper addresses a reconstruction and analysis of the 1957 flood that occurred in the Rambla Castellarda, a tributary of the Turia river. The research is based, among other sources, on a series of extraordinary, high-precision aerial photographs carried out a few weeks after the flood. These images make it possible to recreate the processes observed in this ephemeral river and map the post-event river forms. Results show the behaviour of a Mediterranean aggradational ephemeral stream, very different from the current processes, and allows a comparative reflection to be made about flood processes in different sedimentary contexts. The study reveals that in-channel agricultural activity was, together with floods, the most relevant factor conditioning the river channel adjustment trajectory in that sedimentary context. Finally, the analysis of the impact of the flood in the Tura river highlights the importance of overflows – and therefore the connection between channel–floodplain – both for in-channel processes and in the lamination of floods.

  • Desertification and Degradation Risks vs Poverty: A Key Topic in
           Mediterranean Europe

    • Authors: Jesús Rodrigo-Comino, Rosanna Salvia, Gianluca Egidi, Luca Salvati, Antonio Giménez-Morera, Giovanni Quaranta
      Pages: 23 - 40
      Abstract: Land degradation and, subsequently, desertification processes are conditioned by biophysical factors and human impacts. Nowadays, there is an increasing interest by social scientists to assess its implications. Especially, it is relevant to the potential changes and landscape deterioration on population, economic systems and feedbacks of local societies to such adjustments. Assessing social facets should also be related to desertification risks, integrated socio-economic inputs and environmentally sustainable development perspectives. However, investigations about the effects of land degradation conditioned by global socioeconomic-factors from a holistic point of view are scarce. In this review, we pretend to discuss past and recent findings on land degradation risks related to poverty, especially based on Mediterranean Europe. To achieve this goal, we focused on key socioeconomic forces such as developmental policy, production and market structure, social change and population mobility. Our review showed that regional disparities based on complex dynamics of demographic forces (e.g. migration, fertility and ageing) and economic drivers of change (e.g. industrial concentration, urbanization, crop intensification, tourism pressure, coastalization) are keys to understand Mediterranean regions such as Southern Italy, a region exposed to high desertification risk in Europe. We concluded that the overexploitation of territories, soil and water degradation urban expansion, tourism and unplanned industrialization are some sectors and activities which can be highly affected by political and socioeconomic forces leading to unsustainable forms of land management and types of development. Special attention should be paid to social policies, education and training schemes to reduce rural migration and potentiate territorial knowledge to avoid land degradation, considering other social issues such as poverty or centralization. The potential role of win-win policies abating poverty and reducing desertification risk is evident in Mediterranean Europe and achieving land degradation neutrality necessary.

  • Identification of levels of anthropization and its implications in the
           process of desertification in the Caatinga biome (Jeremoabo, Bahia-Brazil)
           

    • Authors: Nívea Oliveira Santos, Ricardo Augusto Souza Machado, Rubén Camilo Lois González
      Pages: 41 - 57
      Abstract: Desertification is one of the most serious current environmental problems and corresponds to the impoverishment and decrease of moisture in sandy soils located in regions with a sub-humid, arid and semiarid climate, with its main causes related to climatic variations and the resulting negative impacts of human activities. Studies show that the soils located in the Brazilian semiarid and especially in the Caatinga biome have been suffering an intense process of desertification due to the replacement of natural vegetation as a result of economic activities. Most municipalities that have an economy based on agropastoral activities are at the centre of desertification in several centres in Brazil. Based on this context and considering that the original vegetation cover is a preponderant factor for soil conservation, and subsequently for the maintenance of the ecological stability of the Caatinga biome, this work aimed to map the vegetation cover of the Vaza-Barris watershed corresponding to the municipality of Jeremoabo (Bahia-Brazil), with the purpose of identifying and quantifying, in terms of surface, the main types of interaction between human activities and the remnants of the vegetation cover, listing the potential impacts that have a direct consequence on the desertification processes. The delimitation of the vegetation cover was the result processing Sentinel 2A satellite images and the use of the Soil Adjusted Vegetation Index - SAVI. Five thematic classes representative of the study area were identified, classified according to the increasing level of anthropization that allowed us to conclude that desertification causes damage to agriculture, making the areas unproductive, as well as excessive agriculture with inappropriate practices causes the loss of fertility of the soils, aggravating the desertification process. With this, the environmental and social quality is threatened, considering that the main source of income in the municipality of Jeremoabo comes from agricultural activities and these are dependent on climatic conditions, soil conservation and water resources.

  • Identification of desertified and preserved areas in a conservation unit
           in the state of Paraíba – Brazil

    • Authors: Leandro F. da Silva, Bartolomeu I. de Souza, Rafael Cámara Artigas
      Pages: 59 - 78
      Abstract: The objective of this study is to identify and analyse the main characteristics of areas potentially degraded by desertification and of preserved areas using the Soil Surface Moisture Index (SSMI), alongside the Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI). The study is based on a set of points obtained in the field and from the RGB false colour image for the Environmental Protection Areas (EPA) of the Cariri, in the semi-arid region of Paraíba, using a space-time cross-section covering both rainy and dry periods. The results showed that at all points in Desertified Areas, the main characteristics were a low SSMI, high LST and low NDVI in both periods. The Preserved Areas, on the other hand, presented a high SSMI, moderate LST and high NDVI in the rainy period, with the same characteristics repeated in the dry period for SSMI and NDVI, but with a low LST. Timely identification of these characteristics, both in areas degraded by desertification and in better preserved areas, can provide useful information for future decisions relating to the physical and territorial management of the Conservation Unit.

  • Subgrid snow depth coefficient of variation spanning alpine to sub-alpine
           mountainous terrain

    • Authors: Graham A. Sexstone, Steven R. Fassnacht, Juan I. López-Moreno, Christopher A. Hiemstra
      Pages: 79 - 96
      Abstract: Given the substantial variability of snow in complex mountainous terrain, a considerable challenge of coarse scale modeling applications is accurately representing the subgrid variability of snowpack properties. The snow depth coefficient of variation (CVds) is a useful metric for characterizing subgrid snow distributions but has not been well defined by a parameterization for mountainous environments. This study utilizes lidar-derived snow depth datasets spanning alpine to sub-alpine mountainous terrain in Colorado, USA to evaluate the variability of subgrid snow distributions within a grid size comparable to a 1000 m resolution common for hydrologic and land surface models. The subgrid CVds exhibited a wide range of variability across the 321 km2 study area (0.15 to 2.74) and was significantly greater in alpine areas compared to subalpine areas. Mean snow depth was the dominant driver of CVds variability in both alpine and subalpine areas, as CVds decreased nonlinearly with increasing snow depths. This negative correlation is attributed to the static size of roughness elements (topography and canopy) that strongly influence seasonal snow variability. Subgrid CVds was also strongly related to topography and forest variables; important drivers of CVds included the subgrid variability of terrain exposure to wind in alpine areas and the mean and variability of forest metrics in subalpine areas. Two statistical models were developed (alpine and subalpine) for predicting subgrid CVds that show reasonable performance statistics. The methodology presented here can be used for characterizing the variability of CVds in snow-dominated mountainous regions, and highlights the utility of using lidar-derived snow datasets for improving model representations of snow processes.

  • Temporal variability of the urban heat island in Zaragoza (Spain)

    • Authors: José M. Cuadrat, Roberto Serrano-Notivoli, Samuel Barrao, Miguel Ángel Saz, Ernesto Tejedor
      Pages: 97 - 110
      Abstract: We analyse the temporal intensity and variability of the urban heat island (UHI) in the city of Zaragoza (Spain), and assess the role of wind as an important atmospheric conditioning factor. Based on the time data provided by the city’s urban mesoscale meteorological network, the temperature difference between two observatories, one urban (Plaza Santa Marta) and one located on the outskirts of the urban area (Ciudad Deportiva), was calculated for the 2015-2020 period. The results indicate that the temperature in the city centre is very frequently 1º or 2ºC higher than in the surroundings, sometimes even more than 8ºC higher. The UHI is more intense in summer (an average of 2.5ºC per hour) than in winter (an average of 2.2ºC per hour) and more intense during the night than during the day. The maximum UHI value is reached in calm atmospheric situations; however, this value is very limited with winds over 10 km/h and it practically disappears with wind speeds over 50 km/h.

  • Identification of changes in the rainfall regime in Chihuahua's state
           (México)

    • Authors: Indalecio Mendoza Uribe
      Pages: 111 - 132
      Abstract: The impacts of Climate Change are not homogeneous globally or for a country or region as a whole. Consequently, it is essential to carry out studies to identify its effects in particular areas. Due to its geographical and topographic characteristics, Chihuahua's state is vulnerable to the adverse effects of Climate Change. The scarce availability of water resources leads to problems of social pressure and economic impact. This paper analyzes the alteration of the rainfall regime in Chihuahua's state and its association with Climate Change. For this, historical characterization is used; trend analysis using the Mann Kendall test; and calculation of 10 indices of climatic extremes proposed by the Group of Experts for Detection and Climate Change Indices for the precipitation variable. The results showed that the precipitation patterns in the south and southeast of Chihuahua's state have been gradually modifying, with a downward trend in annual accumulated and reduction of wet days. Still, in counterpart, there is a slight intensification of extreme rainfall. This fact added to the growing demand for water resources in the entity, requests for public policies for sustainable management and responsible use by users. Otherwise, there is a risk of experiencing negative effects associated with the over-exploitation of water, not only for the resource users but also for the environment.

  • Strategies for adaptation to climate change in vineyards in the
           Mediterranean basin: the case of the DOCa Rioja

    • Authors: Teodoro Lasanta, Carlos Baroja-Sáenz, Melani Cortijos-López, Estela Nadal-Romero, Ignacio Martín, Enrique García-Escudero
      Pages: 133 - 156
      Abstract: Climate change is promoting increasingly hot and dry conditions in the vineyards of the Mediterranean basin, affecting both the physiology and phenology of the vine, as well as the production and quality of the grape. In this context, adaptation and mitigation measurements against climate change are necessary to maintain high quality wines and varietal typicity, as well as to respond to market demands. The objective of this study is to show adaptation strategies that are being carried out or considered by winegrowers of the Denomination of Origin Qualified Rioja (DOCa Rioja). Among the strategies, the following should be highlighted: changes in the location of the vineyard, either towards areas with irrigation possibilities and very fertile soils (mainly low terraces), or towards higher altitude areas (mainly high glacis), thus trying to avoid the effects of water stress and increased temperatures; and (ii) modifications in the strain conduction system, often replacing the vessel conduction with the trellis conduction, in order to match a greater degree of mechanization of the agronomic tasks and the improvement of the improvement of the vine’s microclimate, especially in the new plantations in very fertile soils. These strategies will be increasingly relevant, taking into account the foreseeable increase in temperatures and droughts in the future climate scenarios. However, the question arises as to whether these strategies will be sufficient or whether it will be necessary to eliminate current restrictions imposed by DOCa Rioja, such as expanding the vineyard in mountain areas or introducing new varieties.

  • Climatic changes and distribution of plant formations in the state of
           Paraíba, Brazil

    • Authors: Rafael Cámara Artigas, Bartolomeu Israel de Souza, Raquel Porto de Lima
      Pages: 157 - 174
      Abstract: The state of Paraíba in northeast Brazil contains four of the seven biomes present in the country: Mata Atlântica, Cerrado, Caatinga and Matas Serranas. On the other hand, Amazônia, Pantanal and Pampa were not found in this area. This special situation allows us to analyse changes in the distribution of these four large Brazilian biomes according to bioclimatic conditions, using the methodology of bioclimatic regime types. Based on the analysis of variables from periods of hydric and thermal vegetation stagnation, obtained from hydric and bioclimatic balances, average monthly temperature and rainfall, that methodology enables us to establish a typology of 27 types of bioclimatic regimes and 243 bioclimatic regime subtypes with the 9 Thornthwaite ombrothermal levels. In Paraíba 4 types of bioclimatic regimes are currently identified (mesophyllo, tropophyllo, xerophyllo and eurythermophilous) and 9 subtypes according to ombrothermal levels. In order to analyse the changes, extreme change situations were chosen: a past scenario with the Last Glacial Maximum (40 ky); and an RCP 8.5 climate change scenario for the CMSS 4.0 model for the year 2070. This enabled 3 bioclimatic regime maps of each of the 3 aforementioned situations to be obtained, providing a map of potential distribution of the plant formations of Paraíba state according to the specific field knowledge and bioclimatic mapping obtained for the present. This paper concludes that a retrocession of the Mata Atlântica can be seen from the Last Glacial Maximum up to the present, losing its optimal bioclimatic conditions and therefore remaining in a highly fragile relict situation in the face of anthropic pressure (sugarcane cultivation and urban expansion); an advance toward 2070 of the Caatinga in its shrub form as a predominant formation is indicated by the projection of climate change in 2070 for the analysed situation, specifically resulting from anthropic pressure, in this case due to livestock activities which have affected this biome in Paraíba since the mid-19th century.

At the landscape level, the challenge is determining the allocation and management of various land cover options. Therefore, for natural resources planning and management, a study characterizing and analysing the territory of interest should be included. This work aimed to analyse the changes and land cover patterns in the city of Pereira, Colombia, within the framework of the Colombian Coffee Cultural Landscape. The evaluated period was between 1997 and 2014, and a Geographic Information System, ENVI 4.8 programme and QGIS programme were used for multitemporal analysis. To describe the land cover transitions, two temporal moments were analysed with Landsat satellite images: one moment was for the year 1997, which was taken in August (Landsat 5), and the other moment was for the year 2014, which was taken in July (Landsat 8). At level 1 of CORINE (Coordination of information on the environment), the areas of land cover corresponding to agricultural areas, forests and semi-natural areas decreased most in the analysis period, while artificial surfaces increased. At level 3, the cover with the greatest decrease in territory was coffee crops, which showed a negative annual loss rate of -3.97%, followed by permanent crops (-2.67%). The continuous and discontinuous urban fabric showed the greatest growth with a positive annual rate of 4.14%. In conclusion, the land cover that lost the most territory was coffee crop, mainly due to political-economic factors, such as the dissolution of the International Coffee Agreement and the National Federation of Coffee Growers that discouraged coffee cultivation and permanent crops. Likewise, sociocultural factors, such as smallholder farmers have guided the changes in land cover and have stimulated productive styles to adapt and remain, increasing heterogeneous agricultural areas.

      Abstract: QGIS is the most popular free geospatial software in the world. QGIS belongs to the Open-Source Geospatial Foundation (OSGeo). Among the main strengths of this Geographic Information Systems are: the incorporation of tools via plugins, and a community of users and developers in constant growth. Despite the importance on the use of QGIS on the scientific community, to date there are no systematic studies indicating how the acceptance of this software has evolved through time. Therefore, the objective of this research was to characterize the scientific production and extent where QGIS has been used as their main geospatial tool. We conducted a bibliometric analysis of documents published in Scopus from 2005 to 2020 (931 manuscripts). The annual rate of publications increase was 40.3%. We found strong and positive correlations regarding the number of contributing code programmers (r=0.66, p<0.005); and the total income of the QGIS project (r=0.88, p<0.001). Seventy-two percent of the publications were included in six fields of study, being Earth and Planetary Sciences the most representative. Italy was the country with larger scientific production, while the USA was the most influential country (being the first, regarding the number of citations). In terms of the countries, the larger number of papers found were from Portugal, Italy, Brazil, and France. The International Archives of the Photogrammetry Remote Sensing and Spatial Information Sciences - ISPRS Archives stands among journals with the largest number of publications (47). In terms of collaborative networks among countries, we found strong links between authors from Germany, Switzerland, Greece, and Spain. Author network analysis showed three solid networks in different fields of study. We observed a favorable trend in the acceptance of QGIS across the world and a widespread development of collaborative networks. The present paper allowed increase the knowledge of geographic information systems, especially the development of scientific production using QGIS.
