    Tracking the recent dynamics of Mt. Vesuvius from joint investigations of ground deformation, seismicity and geofluid circulation (2021)
    Springer Nature
    Details
    Publication Date: 2021-01-15
    Description: We reconstruct the composite dynamics of Mt. Vesuvius volcano in the period 2012–2019 from the study of ground deformation, seismicity, and geofluid (groundwater and fumarolic fluids) circulation and recognize complex spatio-temporal variations in these observables at medium (years) and short (months) time-scales. We interpret the observed patterns as the combined effect of structural changes affecting the volcanic edifice and variations of the dynamics of the hydrothermal system. In particular, we identify a change in the activity state of Mt. Vesuvius. After the activity reached minimum levels in 2014, the centroid of the surface manifestations migrated towards the SE. Episodic variations of co-seismic and aseismic deformation and fluid release, if analysed separately, would likely have been interpreted as pseudo-random oscillations of the background geophysical and geochemical signals. When organised in a comprehensive, multiparametric fashion, they shed light on the evolution of the volcano in 4D (x,y,z, time) space. These inferences play a crucial role in the formulation of civil protection scenarios for Mt. Vesuvius, a high risk, densely urbanized volcanic area which has never experienced unrest episodes in the modern era of instrumental volcanology.

    Self‐stated recovery from flooding: Empirical results from a survey in Central Vietnam (2021)
    Blackwell Publishing Ltd | Oxford, UK

    Publication Date: 2021-06-27
    Description: Social inequalities lead to flood resilience inequalities across social groups, a topic that requires improved documentation and understanding. The objective of this paper is to attend to these differences by investigating self‐stated flood recovery across genders in Vietnam as a conceptual replication of earlier results from Germany. This study employs a regression‐based analysis of 1,010 respondents divided between a rural coastal and an urban community in Thua Thien‐Hue province. The results highlight an important set of recovery process‐related variables. The set of relevant variables is similar across genders in terms of inclusion and influence, and includes age, social capital, internal and external support after a flood, perceived severity of previous flood impacts, and the perception of stress‐resilience. However, women were affected more heavily by flooding in terms of longer recovery times, which should be accounted for in risk management. Overall, the studied variables perform similarly in Vietnam and Germany. This study, therefore, conceptually replicates previous results suggesting that women display slightly slower recovery levels as well as that psychological variables influence recovery rates more than adverse flood impacts. This provides an indication of the results' potentially robust nature due to the different socio‐environmental contexts in Germany and Vietnam.

    Description: This paper, fish genetics and breeding in Nigeria addresses the application of genetics and breeding to fish farming with the view to enhanced aquaculture production in Nigeria. This production technique is not limited to the use of conventional breeding programs nor is it necessary to go through the basic developmental steps of selection and isolation that lead to the domestication and diversification of livestock and crops over thousands of years. With modern molecular genetic techniques and induced breeding, it is now possible to develop and create new fish species .

    Description: Biotechnology per se is not a panacea for the world's problems of hunger and poverty. However, genetic engineering in particular, offers outstanding potentials to increase the efficiency of animal improvement. Thus, biotechnology could enhance global food production and availability in a sustainable way. Case studies from Egypt and India also demonstrate that highly immune genetically modified fishes, transgenic fishes, chromosome engineering and gene banking are very appropriate for fish farmers and consumers in developing countries. As the entire technology can be packaged into the germ cells of fish, it can easily be integrated into traditional small-holder fish farming systems. Except for a few innovative transfer projects, though, the application of biotechnology until now remains concentrated in the industrialized world. Combined with insufficient own scientific and regulatory capacities, the increasing privatization of international aquacultural and fisheries research and the strengthening of intellectual property rights complicate the access of developing countries to biotechnology. Profound constitutional adjustments are therefore essential to ensure that biotechnology does not bypass the poor.

    Description: The estuarine catfish, Chrysichthys nigrodigitatus, is a prized food fish in Nigeria especially in the Niger Delta region. There is a growing concernrn over the sustainability of the fishery in the face of climate change and environmental variability. Studies were conducted on the fecundity, gonadosomatic index and the spawning period of the species. The objectives were to determine the average fecundity of the species and to use the gonadosomatic index to determine its spawning period with the aim of proffering management advice and prerequisites of the species in the face of climate change. A total of 44 females and 40 males were used for the study which spanned the period from May 2011 to April 2012. The fecundity of the species ranged from 3,730.5 eggs to 41,535.9 eggs. There was correlation between the total fecundity and fish weight (p~,01, r= 0.80, n= 44). The regression model for the relationship was expressed as fecundity = 4660.8+4.76 weight. The gonadosomatic index was highest in the month of May and dropped sharply in june signifying that spawning in Chrysichthys nigrodigitatus starts around this period. The implications of these findings in respect to sustainability of the species, and its aquaculture in the face of climate change are discussed.

    Description: A fisheries-dependent surveys was conducted to identify and quantify the species composition of shrimp by-catch and its effect on fishery sustainability. Samples were bought monthly, from October 2009 to June 2010 from landings site, at Apapa-Liverpool market Lagos. 25 fish species belonging to 18 families targeted in other inshore fisheries constituted the by-catch species. The percent of weight compositions of some economically important by-catch species were: Pseudotolithus senegalensis (5.76%),Ilisha africana (14.65%), Pentanemus quinquarius (2.94%), Pteriscion peli (6.60%), Galeoides decadactylus (3.17%), Cynoglossus senegalens is (6.76%) and Chloroscombrus chysurus (10.81%). About 80% of the shrimp by-catch species were juvenile fin fish. However, continuous harvest without appropriate mitigating measures poses a threat to sustainability of coastal capture fisheries. Recommendations are proffered in order to conserve the resources for sustainable development.

    Applying the Values of Geoethics for Sustainable Speleotourism Development (2020)
    Springer Nature
    Details
    Publication Date: 2020-09-01
    Description: Establishing sustainable and responsible speleotourism development is a major challenge and involves complex activities. Adequate theoretical starting point is the application of geoethical values related to the conservation and protection of the caves to be used for touristic purposes. Positive and negative cases of human behaviors towards speleological geoheritage are discussed, in order to highlight what should be done in cave management to avoid malpractices and on what elements could be founded adequate strategies aimed at promoting sustainable speleotourism. This is important to tourism management organizations involved in the promotion of caves and in creating economic opportunities for local populations, while respecting cave ecosystems. Modern cave management must be focused on the protection of the cave ecosystems, finding ways to achieve at the same time an economic development of local communities. But this approach needs the adoption of a geoethical framework of values to be shared by all stakeholders involved so that successful cooperation can be achieved despite differences in interests and expectations. The aim of this paper is to raise the awareness about the need to apply the values of geoethics to speleotourism, stimulating new fields of discussion within the scientific and technical communities involved in studies and activities related to geotourism and geoheritage. The possibilities of developing new ways to manage caves, in order to promote a sustainable socio-economic development of local communities, have to be balanced with the protection of natural environments as much as possible. The proposed theoretical frameworks have the goal to increase the discussion on the best ways of connecting speleotourism to sustainable and responsible cave management, presenting two case studies, and pointing out potential solutions.
