Opis:
Within the framework of the OPCOM project, operational and pre-operational tools have been developed to help the local players and decision-makers in managing the coastal environment. In this context operational or pre-operational model systems were applied to four very different coastal zones. The results were analysed for coastal zone management purposes according to the specific local demands for coastal man-agement in close co-operation with possible first users. This publication describes the experience and most important conclusions derived in the OPCOM project regarding the importance and application possibilities of local operational models in integrated coastal zone management.

Opis:
The study aimed to investigate effectiveness of forest management zoning in conserving biodiversity of Mabira forest reserve. The study sites buffer, production, and strict nature reserve management zones were purposively selected. This was undertaken through investigating woody species diversity, composition and structure. A total of 60 sampling plots with a size of 20 m x10 m were used to collect vegetation data. Variables such as woody plant species identification and counts as well as diameter at breast height (DBH) of trees were done. The result depicted a total of 65 woody species; 39 in buffer, 19 in productions and 37 in strict nature reserve. Of these, only 9 trees species were found common to all zones and their Sorensen similarity coefficient was 0.2213. The population structure of the buffer and strict nature reserve zones was found to be a J - shape pattern, whereas the production zone shown an inverted J-shape pattern. Higher woody species diversity was depicted in the buffer and strict nature zones with (H’=2. 73512) and (H’=2. 68412) respectively, and lower in a production zone (H’=1. 63628). The evenness index value of a buffer zone was (J =0. 746574), strict nature (J= 0.743335) and production (J=0. 555719). The production zone had shown higher IVI values followed by buffer and strict nature reserve zone. The most important woody species identified based on their IVI value were Broussonetia papyrifera (Production), Acalypha neptunica (Buffer), Funtumia Elastica (strict nature reserve). The existing forest management is effective in conserving the biodiversity of the forest reserve. Nevertheless, the production zone was still suffering from exploitation of the surrounding community, hence serve for protecting the remaining management zones from further human interference. Further investigation is also required on the adjacent community perceptions of the forest management zoning.

Opis:
Various types of utilization, conflicting interests and environmental problems call for coastal water management as part of an integrated coastal zone management. This is especially necessary for the Oder (Odra) estuary at the German/Polish border. The river Oder causes severe, ongoing and large scale eutrophication, which limits the ecological and economic value of its adjacent coastal ecosystems. Simulation models are an important tool with which to tackle these practical problems and support management. We present a general concept of a decision support system with an integration of sub-models. Two types of models for long-term water quality forecasts and scenario simulations, as well as short-term prediction of water pollution are available at present. Spatial human-pathogenic virus transport and decay simulations are used as an example to demonstrate their practical use.

Sustainable Coastal Index
Opis:
Integrated Coastal Zone Management is an emerging research area. The aim is to provide a global view of different and heterogeneous aspects interacting in a geographical area. Decision Support Systems, integrating Computational Intelligence methods, can be successfully used to estimate useful anthropic and environmental indexes. Bayesian Networks have been widely used in the environmental science domain. In this paper a Bayesian model for estimating the Sustainable Coastal Index is presented. The designed Bayesian Network consists of 17 nodes, hierarchically organized in 4 layers. The first layer is initialized with the season and the physiographic region information. In the second layer, the first-order indexes, depending on raw data, of physiographic regions are computed. The third layer estimates the second-order indexes of the analyzed physiographic regions. In the fourth layer, the global Sustainable Coastal Index is inferred. Processed data refers to 13 physiographic regions in the Province of Trapani, western Sicily, Italy. Gathered data describes the environmental information, the agricultural, fisheries, and economical behaviors of the local population and land. The Bayesian Network was trained and tested using a real dataset acquired between 2000 and 2006. The developed system presents interesting results.

Opis:
In the rural areas 90% of the Ugandans use plants for their medicinal uses. Communities around Mabira Central Forest Reserve (CFR) harvest plants for medicinal purposes. The increased uptake of herbal medicine is a threat to the abundance and health of medicinal trees. This research determined the species population structure and regeneration status of most abundant woody medicinal plant species in Mabira CFR. Sixty nested plots measuring 20×10 m were established adjacent to transects, 20 plots per management zone. The species sampled were identified, counted, and their diameter at breast height (dbh) taken. Their density was computed. Using the dbh classes and density data, dbh distributions were established. Using Kruskal- Wallis test we ascertained if significant differences existed in medicinal plant species densities for size classes in the 3 zones. Using linear regression we got relationship between plant density and dbh. A regression analysis of In (Ni+1) against di was made to cater for the zero values of abundance per hectare. The population had a steep negative slope, meaning that it is stable and naturally replacing itself. There was a general decline in species density with dbh. The <5 dbh size class had the biggest number of individuals per hectare in the production zone. The production zone had a high regeneration potential due to most individuals being in the smallest size class. Density had a negative linear relationship with dbh. There was a significant relationship between dbh and density of species. The tree species sampled were generally naturally regenerating.

Opis:
The coastal zone is an interactive and dynamic complex of sub-systems, where human activities and natural processes in one sub-system may adversely affect other sub-systems. Therefore, one of the most important issues in the area of coastal zone management (CZM) is to avoid conflicts and to prevent overlapping of development interests of the various resource sectors such as tourism development, land use planning, etc. The GMS-Decide is the software designed to create, organise and analyse data as it relates to the geographical information. It can be used for scientific investigations, resource management and development planning. For CZM purposes, GMS might allow emergency planners and decision-makers to easily calculate emergency response in the event of a natural disaster. In the strictest sense, a GMS is a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information, i.e. data identified according to their locations, which is extremely useful to deal with coastal areas.

Opis:
Pakistan has a population of over 199 million and total road network of approximately 264,400 kilometers that serve about 16.2 million vehicles of all types. According to WHO estimates, there were approximately 30,000 annual Road Crash Fatalities (RCF) in Pakistan in year 2010. Work zone crashes account for significant proportion of all traffic crashes in Pakistan due to higher crash rate as compared to other parts of the highway network. Highway work zone is referred to road area where highway construction, maintenance or activity related to utility maintenance takes place. Workers in highway work zone are exposed to a variety of hazards and face risk of injury and death from construction equipment as well as passing motor vehicles. Safety measures and better understanding of risks involved while moving through the work zone have significant effects on the overall safety climate at work zones. Mismanaged work zone traffic increases the travel time delays, safety issues, vehicle operating costs (VOC) and other associated costs. Performance measures for the work zone traffic management includes user costs (travel time delay, crash cost, VOC), incident response and clearance time, queue length and community complaint. Different work Zone Traffic Management methodologies are being practiced worldwide and extensive research has been carried out at international level on country specific highway work zone safety but in Pakistan very few studies have been carried out on highway work zones. This research aims to critically analyze the impacts of the different Work Zone Traffic Management methods and recommend the best option for Expressways/Motorways in Pakistan. For the purpose of research, the author has selected a section of Motorway (M-2). Two different work zone traffic management methods are being followed in rehabilitation of M-2 .i.e. Parallel/Adjacent Method and Median Cross-Over Method. Performance measures selected for purpose of analysis are Travel Time Delay, Crash Cost (Safety) and VOC and data collected on section of M-2. After critical analysis, it is concluded that Parallel / Adjacent Method results in lesser Travel Time delay and lesser VOC due to higher operating speeds and thus has higher savings, whereas Median Cross over Methods yield more Crash Cost savings. Keeping in view the driving habits / skills, poor maintenance of vehicles in Pakistan and risk of fatal accidents involved in parallel/adjacent method, median cross over method is preferred.

Opis:
The main objective of the paper is to present the performance of special economic zones (SEZs) by province over 25 years of their operation and their role in reducing regional economic disparities. SEZs were created with the aim to mitigate the unemployment problem revealed by the transformation of the Polish economy. It was hoped that, thanks to investment incentives, capital would flow primarily to the regions most affected by the transformation. However, these intentions failed to receive statutory protection. As a result, SEZ investments could be found in southern, central and western Poland, i.e., they were scattered across almost the entire country. Only the eastern, poorest voivodeships enjoyed significantly less interest. This was a consequence of the ownership structure of capital because the zones were clearly dominated by foreign investors. The Polish Investment Zone, the successor to the SEZs, brought some changes in this respect. Simple statistical analyses suggest that, contrary to assumptions, the SEZs have not contributed to the reduction in regional disparities measured by GDP per capita, and may even have increased them. Resolving this question would require more in-depth research.
Głównym celem artykuły jest zaprezentowanie wyników specjalnych stref ekonomicznych (SSE) w układzie wojewódzkim osiągniętych w ciągu 25 lat działalności oraz ich roli w ograniczaniu regionalnych nierówności gospodarczych. SSE utworzono z myślą, aby łagodzić trudności związane z bezrobociem, które ujawniła transformacja polskiej gospodarki. Liczono, że dzięki zachętom inwestycyjnym kapitał napłynie przede wszystkim do regionów najbardziej dotkniętych zmianami. Intencje te nie znalazły jednak ustawowego zabezpieczenia. W efekcie inwestycje strefowe koncentrowały się w południowej, centralnej i zachodniej Polsce, czyli znalazły się na terenie niemal całego kraju. Tylko wschodnie, najbiedniejsze województwa cieszyły się wyraźnie mniejszym zainteresowaniem. Było ono pochodną struktury własnościowej kapitału. W strefach zdecydowanie dominowali bowiem inwestorzy zagraniczni. Pewne zmiany w tym zakresie przyniosła Polska Strefa Inwestycji, następczyni SSE. Proste analizy statystyczne sugerują, że, wbrew założeniom, strefy nie przyczyniły się do zmniejszenia regionalnych dysproporcji mierzonych poziomem PKB na mieszkańca, a nawet mogły oddziaływać w kierunku ich wzrostu. Rozstrzygniecie tej kwestii wymagałoby bardziej pogłębionych badań.

Opis:
To increase the level of management efficiency in the agricultural sector of the economy, it is necessary to substantiate environmental protection measures for the restoration and rational use of natural resources, to ensure the implementation of the sustainable environmental management principles, considering the spatio-temporal patterns of changes in climate and bioclimatic potential of the territory. Using the methods of multivariate statistics and time series forecasting, regularities of changes in climatic conditions in the Steppe zone of Ukraine for 1945–2019 were established, and a forecast of changes in the bioclimatic potential of the region until 2030 was made. It was established that during the research period the average annual air temperature increased by 3.5 °C. The amount of annual atmospheric precipitation varied within 186–778 mm with a variation level of 27.2%, in the last 20 years it was determined to decrease by 40% – to 500–300 mm. It has been proven that the inertial probability of repeating hot years is estimated at 0.58, and the possibility of repeating wet years at 0.46. As a result of forecasting, it was determined that if the trend of climatic conditions is maintained, there will be a stable trend-cyclic increase in the average annual air temperature by 0.06 °C per year and a decrease in the amount of annual precipitation by 62.0 mm per year. This resulted in an 18.7% increase in solar radiation on the soil surface and a 26.0% decrease in climatic losses on soil formation, which reduced the rate of the natural ability to reproduce soil fertility. In particular, the bioproductivity of plants decreased by 62.0%, and the probability of its further decrease by 20% is predicted. Over the past 20 years, the coefficient of natural humidification has decreased by 66.4%, and it is predicted to decrease by 20%. The obtained results confirm significant climatic changes and their negative manifestations on the reduction of bioclimatic potential in the Steppe zone of Ukraine, the deterioration of agricultural production conditions, the reduction of harvests, the self-regenerating and self-regulating function of steppe soils.

Opis:
Surveys were carried out in five local government areas of Ogbomoso Agricultural Zone Nigeria during planting season in 2010 to investigate rural farmers perceptions and management practices of insect pests of fruit vegetables. The survey involved 150 randomly selected farmers who were interviewed using structured questionnaire. Fruit vegetables planted by the farmers were okra, tomatoes, pepper and garden egg. Reasons given by farmers for cultivating fruit vegetables were significantly favored by age category, educational qualification, and secondary occupation of farmers (x2 = 4.757, P = 0.029). Field insect pests were perceived as the major production constraint to fruit vegetables in this zone. Majority of the farmer estimated 78.4 % rated insect pest as the most serious pest infesting fruit vegetables, the insect pests were grasshopper (Orthoptera), beetles (Coleoptera) and caterpillar (Lepidoptera). Integrated pest management module consisted basically of chemical and cultural control strategies, with weeding, shifting cultivation and crop rotation as main cultural control methods. More than 76.7 % of the farmers make use of cultural control because of unavailability and cost of chemical insecticides. Only 23.3 % had access to chemical insecticides in controlling insect pest of fruit vegetables.

Opis:
The Drentsche Aa catchment in The Netherlands, which has nearly untouched natural river valleys, is a designated Natura 2000 area. Agriculture is practiced on the adjacent higher-lying ground. A set of measures was drafted to achieve climate-proof solutions in the short term by reducing the effects of a drier climate on nature and agriculture. These measures must have no adverse effects. In order to check this, the Hunze and Aa’s Water Board investigated the feasibility of using groundwater for sprinkler irrigation in parts of the catchment. In the study, the SIMulation of GROundwater and surface water levels (SIMGRO) hydrological model was used in order to model future scenarios with different water level strategies and climate scenarios. The modelling examined various measures in the nature and agricultural areas to optimise the hydrological situation for both land use functions. In addition, the effect on the nature areas of abstracting groundwater for irrigation was determined for buffer zones of different widths. The findings have indicated the policy direction to be taken by both the water board and the province, as well as offer them opportunities to deal with the requests for withdrawals in the near future by the means of future-proof general rules.

According to UN experts, by 2030, about half of the world’s population will suffer from a shortage of fresh water, which may cause future hostilities and conflicts. In this regard, extraction of such a valuable mineral as groundwater must be rationally managed. However, practice has shown that managing and protecting the groundwater resources is a very challenging task. As part of the analysis pertaining to the problem of legal regulation of groundwater extraction from transboundary aquifers and complexes, it is proposed to consider this aspect on the example of Russia. The problems of regulation of rational use and protection of fresh water in the bilateral agreements of the Russian Federation were identified; a methodology for managing groundwater extraction in the territory of a transboundary aquifer was developed, dimensions, parameters and factors affecting the formation of a transboundary zone were determined (using the example of research and analysis of water intake activities in the border territories of the Russian Federation and the Republic of Estonia).

The involvement of a local public school, and the joint work of local teachers and of local and international researchers, was chosen as a dissemination method because of the role of the school as an educational centre and the natural interest and curiosity characterising the schoolchildren. As the subject of the experience of dissemination a beach-dune system was considered suitable because of it was near, familiar and easy to reach, and also because of the economic importance of such environments, which generate considerable income as a result of tourists frequenting them. In environmental education, however, less emphasis is placed on this particular environment. A test performed before and after a school trip to the beach showed an increase in knowledge among children about beach-dune systems. Correlations between the gender and background of the children with their previous knowledge and information acquired from the field experience were analysed, and found to be not significant. All the children were equally receptive to environmental issues, regardless of their gender or background (urban/rural environment). One of the main results obtained through this experience is the effectiveness of sharing knowledge with local people, as stakeholders of study sites. The next step in the process of disseminating scientific knowledge for the benefit of the local community should be to examine its possible long-term effects.
