The escalating impact of climate change has become a significant global concern, particularly in urban environments through the risk of flooding, due to intensified precipitation patterns. Nature Based Solu-tions (NBS), offer effective strategies for mitigating flood risks by enhancing stormwater management and promoting urban resilience. Multicriteria Analysis (MCA) has shown to be useful for identifying suitable areas for NBS, however, there is limited research on its application specifically for urban flood resilience in Sweden. Therefore, this study aims to develop a GIS-based suitability mapping framework within MCA method for allocating suitable areas for two NBS measures: Retention Pond (RP) and Detention Basin (DB), applying it to a case study in Sweden. The study employs a mixed-method approach and consists of (1) framework develop-ment through a literature review, geospatial data assessment, and key-informant interviews, and (2) application of the framework to a case study area in Sweden. In the case study area, the resulting suitability map indicates that 7.5 % of DBs and 7% of RPs met all criteria. Key-informant interviews with local experts provided valuable insights, particularly the exclusion of hazardous zones as well as emphasizing the importance of considering not only biophysical characteristics, but also socio-cultural factors. In conclusion, this study contributes to the body of knowledge on NBS suitability mapping. The findings offer guidance to climate strategists and urban planners on a municipal level, selecting optimal locations for NBS strategies for urban flood resilience and stormwater management.

IN THE ENGLISH LANGUAGE The subject of my doctoral dissertation is an exploration of fishing rights as a collection of a wide range of legal norms regulating the behavior of the recipients only in the performance of fishing, but also in civil, administrative and criminal relations with the breeding and hunting fish related. Due to the current lack of scientific literature on this topic, the thesis also basic definition and status of the Czech Fishing rights in the legal system of the Czech Republic and important connections not only in relation to the institutions of environmental law, but also of civil and criminal law. Basic Institutes of fishing rights are always described as in historical context, as from the time of its inception developed, as well as in international comparisons of countries that their cultures are very close to us.

The aim of this doctoral dissertation is to assess the probable impact of ionizing radiation on the public health and the environment (including fauna and flora) in the vicinity of nuclear power engineering objects (in case of the Maišiagala near-surface radioactive waste repository – by evaluating the possible impact on the human health, while in case of the Ignalina NPP cooling basin, Lake Drūkšiai – by evaluating the possible impact on the freshwater ecosystem biota) by applying probabilistic methods as well as to determine whether this activity after assessment of its character and impact on the environment meets the standards valid in the Republic of Lithuania or in the European Union and is permissible at a selected site at present or in the future. In the work two main programs, RESRAD-OFFSITE and ERICA, using scattering of site-specific parameter values and probabilistic (correlation, regressive, sensitivity, etc.) analysis, have been applied. It has been determined that in the environment of the Maišiagala repository after installation of additional protective barriers the annual effective human exposure dose is significantly lower as compared to the limited dose and 95th percentile dose not exceed the exposure of 1 mSv per year regulated in the hygiene standards. The exposure dose rate of standardized organisms of Lake Drūkšiai, the Ignalina NPP cooler, freshwater ecosystem biota due to the INPP discharges and waterway radionuclide migration from a hypothetic...

Population escalation in the developing world has been associated with increased poverty, food insecurity and environmental degradation. The situation in Rwanda, with 2.82% annual population increase is no exception. The objective of the present study was to investigate an innovative integrated system of sustainable production suitable for resource-poor rural farmers, the Integrated Rabbit–Fish–Rice (IRFR) system. The study was targeted towards contributing to Rwanda government’s goals of eradicating extreme poverty and hunger, enhancing food security as well as abating environmental degradation. Three experiments, were carried out between 2008 and 2010, and designed to fertilise pond water with rabbit droppings and boost phytoplankton production. We also used results from our previous study, conducted in 2005 in the same ponds and under similar experimental conditions, especially rabbit and fish species and age, fishpond dimensions, as well as the fertilisation mode. The fishpond effluent was re-used to irrigate rice fields rather than being discharged into the environment. This study advocated the potential adaptation of rabbits to wetland conditions and the role of rabbit droppings as organic fertilisers in providing a better environment for fish production. On-farm resources, including rabbit droppings, were the main source of nutrients in the system. The analysis of nutrient flow revealed that 27% N and 79% P of the total nitrogen and phosphorus in fertilizing input in fishponds were supplied by rabbit droppings only. Nile tilapia Oreochromis niloticus were able to recover 18.5–37.6% N and 16.9–34.3% P of the total nitrogen and phosphorus inputs, the rest being accumulated in the pond water and the sediment, making them useful for soil fertilisation. The re-use of nutrient-rich effluent in rice irrigation increased rice production, allowing a successful complete substitution of inorganic fertilisers. The irrigation also reduced environmental pollution as the water seeping through rice field was 31.8 and 83.3% less concentrated in total phosphorus and nitrite pollutants, respectively, than was the pond water. Economically, the IRFR generated up to 597% net return over that of the rice inorganically fertilised, thereby substantiating the sustainability of the system. Overall, it is concluded that the IRFR system works well, is readily applicable, and capable of high, diversified, and sustainable production on limited land. As such, the study demonstrates the potentialities of the IRFR system to contribute successfully to poverty reduction, and the enhancement of food security in rural areas. The system promises economic returns and is environmental friendly. The research recommends the optimal range of rabbit density, that is, 800–1200 rabbits per hectare of pond, and the best fish stocking density, that is, 3 fish.mˉ², for a sustainable IRFR culture system. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.

A sustainable society is a society that satisfies its resource requirements without endangering the sustainability of these resources. The mineral endowment on the African continent is estimated to be the first or second largest of world reserves. Therefore, it is recognised that the African continent still heavily depends on mineral exports as a key contributor to the gross domestic product (GDP) of various countries. These mining activities, however, do introduce primary and secondary environmental degradation factors. They attract communities to these mining areas, light and heavy industrial establishments occur, giving rise to artisanal activities. This study focussed on satellite RS products as an aid to a mine’s operations and the monitoring of its environment. Effective operational mine management and control ensures a more sustainable and profitable lifecycle for mines. Satellite based RS holds the potential to observe the mine and its surrounding areas at high temporal intervals, different spectral wavelengths and spatial resolutions. The combination of SAR and optical information creates a spatial platform to observe and measure the mine’s operations and the behaviour of specific land cover and land use classes over time and contributes to a better understanding of the mining activities and their influence on the environment within a specific geographical area. This study will introduce an integrated methodology to collect, process and analyse spatial information over a specific targeted mine. This methodology utilises a medium resolution land cover base map, derived from Landsat 8, to understand the predominant land cover types of the surrounding area. Using very high resolution mono- and stereoscopic satellite imagery provides a finer scale analysis and identifies changes in features at a smaller scale. Combining these technologies with the synthetic aperture radar (SAR) applications for precise measurement of surface subsidence or upliftment becomes a spatial toolbox for mine management. This study examines a combination of satellite remote sensing products guided by a systematic workflow methodology to integrate spatial results as an aid for mining operations and environmental monitoring. Some of the results that can be highlighted is the successful land cover classification using the Landsat 8 satellite. The land cover that dominated the Kolomela mine area was the “SHRUBLAND/GRASS” class with a 94% coverage and “MINE” class of 2.6%. Sishen mine had a similar dominated land cover characteristic with a “SHRUBLAND/GRASS” class of 90% and “MINE” class of 4.8%. The Pléiades time-series classification analysis was done using three scenes each acquired at a different time interval. The Sishen and Kolomela mine showed especially changes from the bare soil class to the asphalt or mine class. The Pléiades stereoscopic analysis provided volumetric change detection over small, medium, large and recessed areas. Both the Sishen and Kolomela mines demonstrated height profile changes in each selected category. The last category of results focused on the SAR technology to measure within millimetre accuracy the subsidence and upliftment behaviour of surface areas over time. The Royal Bafokeng Platinum tailings pond area was measured using 74 TerraSAR-X scenes. The tailings wall area was confirmed as stable with natural subsidence that occurred in its surrounding area due to seasonal changes of the soil during rainy and dry periods. The Chuquicamata mine as a large open pit copper mine area was analysed using 52 TerraSAR-X scenes. The analysis demonstrated significant vertical surface movement over some of the dumping sites. It is the wish of the researcher that this dissertation and future research scholars will continue to contribute in this scientific field. These contributions can only assist the mining sector to continuously improve its mining operations as well as its monitoring of the primary as well as the secondary environmental impacts to ensure improved sustainability for the next generation. / Environmental Sciences / M.

La fin de la Seconde Guerre mondiale, la guerre froide, la cohabitation pacifique, les mouvements d’indépendances, la fin du monde bipolaire, les crises multiformes et successives (culturelle, sociale économique et financière), voici autant d’événements qui ont changé les conceptions et la vision même du monde. L’initiative privée est à nouveau plébiscitée sur la scène mondiale. En effet, la rencontre entre le savoir-faire (financier et technique) du secteur privé et un secteur public ambitieux mais très limité, symbolisée dans le sigle « PPP », devient la formule gagnante.De nouveaux espaces font leurs apparitions, encouragées par le vent de l’intégration régionale et économique. Le mouvement de décentralisation propulsant celui de la coopération transfrontalière, nous assistons de plus en plus à une lente mais très prometteuse reconfiguration des dynamiques transfrontalières un peu partout dans le monde. Certaines régions offrent des perspectives très intéressantes, aussi bien sur le plan de la coopération transfrontalière que des PPP. C’est notamment le cas de la région francophone de l’Afrique des Grands Lacs. Cerner les PPP et la coopération transfrontalière, vérifier leur complémentarité et enfin suivre le mécanisme de réappropriation de ces deux concepts dans la région francophone de l’Afrique des Grands Lacs : voici les principaux objectifs que s’est assigné ce travail de recherche. / The end of the Second World War, the cold war, the peaceful cohabitation, the movements of independences, the bipolar end of the world, the multi-form and successive crises (cultural, social economic and financial), here is so many events which changed the designs and the vision of the world. The private initiative is again approved by a large majority on the world scene. Indeed, the meeting enters the know-how (financial and technical) of the private sector and the ambitious but very limited public sector, symbolized in the initials "PPP", becomes the winning formula.New spaces make their appearance encouraged by the wind of the regional and economic integration. The movement of decentralization propelling that of the cross-border cooperation, we assist more and more a slow but very promising reconfiguration of the cross-border dynamics almost everywhere in the world. Certain regions offer very interesting perspectives, as well from the point of view of the cross-border cooperation as the PPP. It is in particular the case of the French-speaking region of Africa of Great Lakes. Encircle the PPP and the cross-border cooperation, to check their complementarities and finally to follow the mechanism of reappropriation of these two concepts in the French-speaking region of Africa of Great Lakes: here are the main objectives that assigned this research work.

vi Abstract Continental subspecies of the great cormorant (Phalacrocorax carbo sinensis) is the Czech Republic's most important fish-eating predator. It causes damage to production fish, as well as sport fishermen and even after its removal from the Czech list of endangered species in 2013, it did not disappear from the spotlight of both local fishermen and researchers. This thesis evaluates the qualitative and quantitative composition of the cormorant's diet during winter 2011/2012 at two selected locations: the Žehuň pond (Kolín district) and Berounka river in the natural reserve Zábělá near Pilsen. This work studies the main components of cormorant's diet in the selected locations and evaluates potential fluctuations and changes in its composition during winter. The study also conducted the analysis of the proportion of commercially harvested valuable fish in cormorant's diet and studied its diversity of the species spectrum. The resulting data for the two sites were compared with each other and with relevant literature. Regurgitated pellets analysis, as well as analysis of diagnostic bones and fish remains located at the sleeping roosts (night roosts) were used for the diet analysis. It was found that at both sites roach was the most caught fish, but from the point of view of total biomass, it was...
