Abstract: Sustainable development of coastal systems and low-laying inland areas require replacement of artificial coastal stabilization and protection structures with “soft” transplanting techniques of native, salt-tolerant plant species. They can effectively minimize erosion and reduce storm damages with minimal negative impacts to natural ecosystems. Ecosystem services require searching for well adapted plants with extensive root systems and studying their ability for erosion and flooding control. Although, the Bulgarian Black Sea Coast is relatively protected from sea floods due to the small amplitude tides, extreme storms may cause flooding, erosion and destruction of communities of dominant sand stabilizers Leymus racemosus (Lam.) Tzvelev subsp. sabulosus (M. Bieb.), Ammophila arenaria (L.) Link and Carex ligerica J. Gay. In such cases Galilea mucronata (L.) Parl. colonizes territories from these dune pioneers and become a major dune stabilizer. This study aims to establish the viability of this species and possible negative consequences during simulated flooding experiments and thereby to investigate its capacity as dune stabilizer. The experiments established that G. mucronata were very tolerant to immersion impact and salt stress. Whole plants stay viable longer than the flood with a maximum duration along the Bulgarian Black Sea Coast, and rhizomes were able to regenerate after 30 days in seawater. Statistical analysis of experimental data shows that the water itself as a defining factor increase rhizomes viability, biomass and roots to shoots allocation, whereas other factors, such as duration of immersion and temperatures of sea water have not significant effect. G. mucronata were much less tolerant to water immersion than other psammophytes, but demonstrate a high potential to be a key species for dune stabilization and could contribute to the protection of coastal sands during storms.

Abstract: Groundwater can be effectively managed when reliable information is available for planning purposes. The integration of GIS and RS provides a significant approach for assessing groundwater potentiality. This study assessed the role of GIS and RS in groundwater resources management and planning in Afikpo sub-basin of Nigeria, based on the integration of thematic maps such as geology, slope, lineament, land use/land cover and drainage map of the study area. The study revealed that the groundwater potential zones in the study area had excellent, very good, good, moderate and poor prospects with an aerial extent of 136.31 km2, 1035.44 km2, 1432.26 km2, 472.48 km2 and 13.22 km2 respectively. The large aerial extent of favorable groundwater recharge potentiality in Afikpo sub-basin was found to have been as a result of the high amount of lineaments and the sedimentary geologic environment. The study further showed that for effective water resources management and planning, the integration of GIS and RS, which could serve as decision support tool needs to be adopted effectively in Nigeria.

Abstract: This commentary was written as part of a travel symposium organized by the Calotte Academy between Finland, Russia, and Norway entitled “Resilience Related to Sustainable Development in Globalization” which occurred from the period of May 30 to June 5, 2016. The focus is in particular on environmental perspectives towards industrial mining and nature protection at community level. As the socio-economic and political systems of communities evolve in time and space through globalization, the challenge remains for humans to meet the needs of present without compromising the ability of future generations. One of the crucial examples in today’s world includes locating industrial mines near protected areas. In general, this raises concerns of endangering ecological landscapes and undermining human needs. However, there are possibilities for sustainable development to the immediate community. For instance, by means of employment in the mining sector incorporated with the establishment of sustainable environmental management schemes. Using a method approach of document review, a case study of Hannukainen mine near Pallas-Yllas National Park in Finnish Lapland is analyzed. This paper responds to the 2013 Environmental Impact Assessment report by Northland Mines Oy which planned to re-open mining operations in 2016 but faced resistance. Both problems and benefits posed by mining to the human and natural environment are highlighted including human reactions to such problems. It then concludes by proposing possible implications for sustainable development at community level.

Abstract: This work was carried out to assess nutraceutical values of two prominent wild edible fruit, Hyphaene thebaica (L.) Mart. and Borassus aethiopum Mart. from family Arecaceae. Determination of phytochemical, proximate, minerals and antioxidant potentials were carried out. The proximate analysis of the moisture, ash content and crude fat reveals (6.74%, 6.88%, 7.29%, 6.53% and 7.10%, 7.23%) for H. thebaica and B. aethiopum respectively. The B. aethiopum ranked highest in crude fibre (32.15% ), while the highest carbohydrate content was determined in H. thebaica (65.90% ), the protein content of both fruits were observed to be low (8.33±1.4%) and (3.34% ) for H. thebaica and B. aethiopum, respectively. The mineral analysis revealed that in both samples sodium (Na) was highest 14.06mg/g in B. aethiopum and 14.54mg/g, in H. thebaica, Calcium (Ca) 6.20mg/g in B. aethiopum and H. thebaica 5.00±0.06, Potassium (K), 4.57mg/g in B. aethiopum and H. thebaica 5.60mg/g, Magnesium (Mg) 2.03mg/g, in B. aethiopum and H. thebaica 1.53mg/g. The antioxidant activity of the aqueous extracts were determined and compared with the standard vitamin C, using stable 2, 2-diphenyl-1-picryl-hydrazyl (DPPH) and ascertained by measuring reducing power, the extracts showed promising antioxidant activity at 0.5mg/ml, and the IC50 values were calculated using linear regressions (0.86, 0.98, and 1) for vitamin C, B. aethiopum and H. thebaica, respectively. The results indicated that B. aethiopum and H. thebaica fruits possessed nutraceuticals values very much comparable with the commercial fruits reported earlier such as Magnifera indica, Anarcadium occidentalis, and Psidium guajava just to mention but few.

Abstract: Inadequate access to safe water use remains a global issue and a threat to the wellbeing of people. This led to the dependence of households sourcing water from unprotected means. As a result of shortcomings in the nations water supply system, there is a prevalence of some sanitation and water related diseases like cholera, diarrhoea, among others. Important relationship between household access to safe water use and diarrhoea incidence were identified as well as other determinants of diarrhoea which include socioeconomic and environmental such as age of child, toilet facility, place of residence, mother’s literacy level and household wealth status. Policy actions were identified as synergy between water and sanitation sector should reflect in the reduction of water related diseases in the country.
