Ubuoh, E. A, Uka, A. and Egbe, C.
The study focused on the Effects of Flooding on Soil Quality in Abakaliki Agro-ecological Zone of South-Eastern State, Nigeria, for proper soil and flood management to avert soil l degradation. Soil samples were collected from three different floodplains and from arable land at the middle of the stream as control at the depth of 0-30cm, and were used for the determination of the selected soil quality. The treatments were replicated five times and data collected were analyzed using analysis of variance for complete randomized (CRD). All the soil properties assessed were significantly different (p<0.05) among the study locations. The results further showed that apart from sand, BD, gravimetric moisture that were higher in control, silt, clay and porosity were recorded highest mean values than control. Mean pH in floodplains recorded mean value of 5.9 being acidic than control with the mean of pH5.38. Also apart from Avail.P(38.50ppm),OC(1.89cmol/kg), Nitrogen (0.15cmol/kg), ECEC(18.16%) and BS(89.65%) being higher in control than floodplains, the mean of OM (2.5cmol/kg), Ca (10.5cmol/kg), Mg(4.7cmol/kg),K(0.14cmol/kg), Na(1.06cmol/kg) and EA(2.07) were higher in floodplains than control, which could support farming during flood cessation for increased food productions. Based on the results, it is recommended that flood best management practice should be encouraged in order to retain soil nutrients, reduce soil and water pollutions for ecosystem sustainability

Active recovery is one method to reduce post-exercise blood lactic acid concentration. Active recovery performed in warm water has not been well-recognized. The objective of this study was to find the effect of active recovery in warm water on the reduction of post-exercise blood lactic acid concentration. This study employed separate sample pre-test post-test group design using 28 male healthy white Rattusnorvegicus rats aged 3-4 weeks, with body weight of 150-200 grams, they were selected randomly. Samples were divided into four groups, K0, K1, K2 and K3, to be subjected to blood lactic acid concentration measurement. The four groups received different treatment. K0 (control group) received no treatment, while the K1 group received momentary exercise program. K1 and K2 groups received treatments of momentary physical exercise and warm water recovery. The temperature for K1 was of 35-37 oC and K2 was 33-35 oC. Momentary physical exercise in this study was swimming activity in fresh water, which achieving 80% of maximum working capacity and a load of 9% of body weight. Recovery program, comprising swimming exercise without load for 5 minutes, was performed immediately after physical exercise. Result revealed that after active recovery in 35-37 oC water, the concentration of lactic acid became 1,60 mMol/l and reach 2,1 mMol/l at 33-35 oC water temperature. Data were processed using descriptive statistics and inferential statistics (normality test, homogeneity test, anacova test, LSD (least significant difference) test, and independent t test), with significance level of 5%. Independent T test revealed reduction of lactic acid concentration of 4,5 mMol/l in group receiving recovery treatment in warm water 35-37 oC . Both group showed significant difference (p = 0.00) in that treatment. So the treatment of active recovery in warm water can be alternative way to reduce levels of blood lactic acid and it need to develop further research in humans or by the method of applying warm compresses on the active muscle. The further research may applicate in environments with a wide range of temperature variation to find the optimal temperature in the recovery

Gender divisions of labor, roles and responsibilities influence the access, use and management of natural resources especially among rural communities. Forests are the key components of biodiversity and main source of livelihood in Kenya. The main purpose of this study was to investigate the practical and strategic needs of different gender groups in relation to access, use and management of forest resources in Elgeyo Marakwet County, Kenya. The total sample size for this study was 167 respondents, three focus group discussion involving community forest associations and five key informants. The study utilized descriptive analysis techniques where quantitative data was analyzed and presented using frequencies and percentages while qualitative data were summarized and interpreted in line with the research objective. Results are presented in form of figures and tables. The findings shows that 28.4% of the male obtained poles; 23.0% of obtained timber whereas 35.6% of the women obtained firewood and 23.5% obtained medicine from the forest. Further, 12.8% of the females and 7.1% of the males depended on the forest for food. Results shows 37.0% women and 31.0% men reported that food security was an important factor in the access, use and management of forest resources. Some 28.4% male and 23.3% female reported the utilization of forest is aimed at protecting land and watersheds, whereas, 21.8% male cited conservation of biodiversity as compared to 18.5% of the female respondents. The findings show that women livelihoods were engaged more with food and other food related forest resources such as fruits and vegetables; whereas men were more engaged with construction and furniture making. The study findings shows that involvement of men and women in decision making on matters concerning the use of forest resources was a key element in achieving sustainable forest resource management. For effective and sustainable management of forest resources there is need for participatory management where the government departments and community work together to co-manage forest resources especially involving County governments.

Waters of Kura River are main sources for drinking water in Azerbaijan. Therefore, any decrease of quality of water creates danger for environmental protection issues of the whole region. Heavy metals (HM) are one of the main pollutants of the water. Diluted and highly-dispersed forms of HMs forming various complexes with the components of natural environment, then can be transferred by the water flows as well as they can be accumulated in the bottom sediments (BS) and water organisms. For efficient assessment of ecological state of the environment, it is necessary to have sustainable control of HMs content in all links of the following hain: abiotic environment (water, bottom sediment) - biotic environment (benthophage, plankton, phytophages euryphage predator). Present study is devoted to detection of general tendency of content and distribution of HMs in waters, bottom sediment of lower reaches of Kura River and bioaccumulation of toxic metals in organs and tissues of fishes of various ecological groups.

En Côte d’Ivoire le point le plus sensible, en ce qui concerne la pression anthropique sur les écosystèmes, est certainement la zone lagunaire d'Ebrié, au niveau de laquelle s’est développée la ville d’Abidjan. Pour évaluer le niveau de contamination de certains éléments potentiellement toxiques ou PHE (Potential Harmful Elements) dans les eaux de ce système aquatique, 32 échantillons de sédiments de fond ont été prélevés. Les concentrations en PHE (Cu, Zn, As et Pb) ont été mesurées dans la fraction fine (<63μm) de ces sédiments. Aussi, les facteurs d’enrichissement (EF) et la contribution anthropique dans les concentrations déterminées, ont été calculés. Les résultats obtenus montrent des concentrations en PHE, évoluant de 31,7 μg.g-1 (Cu) à 515,14 μg.g-1 (Zn). Plus de 70% des échantillons analysés présentent des valeurs de concentrations en PHE comprises entre les valeurs seuils ERL (Effects Range-Low) et ERM (Effects Range-Median), qui sont des références internationales pour évaluer la qualité des sédiments. Ces résultats traduisent ainsi la mauvaise qualité environnementale des sédiments de la lagune Ebrié. La contribution anthropique en PHE dans les concentrations totales mesurées, est supérieure à 50%, excepté le Cu (38,51%). Sur l’ensemble de la zone étudiée l’enrichissement en PHE est modéré, voir significatif notamment pour la zone nord (baies de Cocody et du Banco) et la zone sud (baie de Biétry), avec des EF compris entre 2 et 10. Ces trois zones peuvent donc présenter des risques sanitaires pour les activités de pêche et d’aquaculture, vu le niveau de contamination. Cette contamination en PHE dans ces trois zones provient majoritairement des activités industrielles, mais également des dépôts atmosphériques et des activités domestiques
Summary: In the Ivory Coast the point with the most sensitive as regards the anthropogenic pressure on ecosystems, is certainly the lagoon area of Ebrié, at the level of which has developed the city of Abidjan. To assess the level of contamination of some potentially toxic elements or PHE (potential harmful elements) in the waters of this aquatic system, 32 samples of bottom sediments were collected. The concentrations in PHE (Cu, Zn, As, and Pb) have been measured in the fine fraction (<63μm) of these sediments. Also, enrichment factors (EF), and the anthropogenic contribution in the concentrations determined, have been calculated. The results obtained show concentrations of PHE, evolving from 31.7 μg.g-1 (Cu) to 515,14 μg.g-1 (Zn). More than 70% of the samples analyzed have values of concentrations in PHE understood between the threshold values ERL (Effects Range-Low) and ERM ( Range-Median effects), which are international references to assess the quality of the sediments. These results thus reflect the poor environmental quality of the sediments of the Ebrié lagoon. The anthropogenic contribution in PHE in the total concentrations measured, is greater than 50%, except Cu (38.51%). On the whole of the area studied the enrichment in PHE is moderate, see especially significant for the Northern Zone (bays of Cocody and the banco) and the Southern Zone (Bay of Biétry), with EF between 2 and 10. These three areas can therefore present health risks for fisheries and aquaculture activities, given the level of contamination. This contamination in PHE in these three areas is dominated by industrial activities, but also of atmospheric deposition and domestic activities.

The present study aimed to calculate water quality index (WQI) by the analysis of different physico-chemical parameters on the basis of Weighted Arithmetic Index in order to assess the suitability of water for drinking, irrigation purposes and other human uses. The different Physico-chemical parameters like Temperature, Transparency, Turbidity, Total Dissolve Solid, Total Suspended Solid, Total Solid, pH, EC, Chloride, Alkalinity, Total Hardness, Ca as Ca Hardness, Ca as CaCO3 Hardness, DO, BOD, COD, Nitrate, Nitrite and Total Phosphate (TP) were measured periodically at 7 sampling sites during March to May 2016. The WQI values in the present investigation were reported to be less than 53 (52, 48, 50, 47, 42, 44 and 48) at all the sampling site i.e. Sphatikshila, Arogyadham, Jankikund, Pramodvan, Ramghat, Karwi bridge and Surajkund Stations respectively. It indicates that the water quality is bad and not totally safe for human consumption. In the present study an attempt has been made to apply the WQI as useful method in assessing the suitability of water for various uses.

Basavarajappa H.T, Dinakar S and Manjunatha M.C
Principal Component Analysis (PCA) analyzing the patterns in high resolution on satellite data is an Advent Statistical Technique (AST) that shows its application in enhancement of linear features. PCA works on basic assumptions such as, linearity, pattern recognition, large existing variances & extraction of linear relationship among a set of variables. The present aim is to enhance the linear features using PCA technique on IRS-1D LISS-III image. PCA plays an important role in Remote Sensing for geological information extraction of fault, fissures, joints etc. Efforts have been made to evaluate the PCA analysis on all bands of Visible and Near-Infrared and Short-Wave Infrared of Indian Remote Sensing (IRS) satellite image using GIS software’s. The results show the ability to enhance the lineaments focusing on groundwater investigations in Southern tip of Karnataka State.
