Abstract:

Flood on March 17 in the Celeng River, Wukirsari Village, D.I. Yogyakarta became the biggest flood that ever happened on the Bog River. Floods are caused by heavy flow of water from the hills in the Imogiri and Dlingo areas. The Celeng River overflowed and submerged four hamlets in Wukirsari Village, Imogiri District. This study aims to determine flood control efforts in the Celeng sub-watershed area. The research location is in the Kali Celeng sub-watershed, Wukirsari, Imogiri, D.I.

Abstract:

Based on the long-term studies of water regime of the Oka River floodplain and its left tributary, the Pra River, the data on maximum water levels during the floods at the Ryazan gauging station have been summarized. According to the series of observations a downward trend in the maximum water level from 1945 to 2010 was revealed. During the years of maximum spring floods, backing of the Pra River by the Oka River waters reaches a distance of more than 160 km upstream. In 1997 the Oka floodplain was for the first time not flooded with water. An increase in average annual air temperatures has b

Bankline changes due to erosion and accretion and the total volumetric change in river channel were measured using Remote Sensing and Geographic Information System approaches. The study showed that erosion was more pronounced in both the right and left bank as compared to accretion. The study revealed that bank width area of the lower basin of Pra Ri

Abstract Illegal mining and inappropriate use of agrochemicals have exacerbated surface water pollution in Ghana. The quality of water has changed, and knowledge of their current condition is important for formulating policies to conserve the country's water bodies. This study assessed the quality of surface waters in Ghana's Pra River Basin. A survey of 344 local farmers randomly sampled was conducted and a physicochemical analysis of 33 water samples collected from 25 rivers in the basin. Boreholes are the main source of drinking water for 85% of farmers, and they assessed water quality by i

The indicator is a commonly used measure of water stress and defines thresholds of 1,700, 1,000 and 500 m3/capita/annum as water stress, water scarcity and absolute scarcity, respectively.

Abstract:

Policy effectiveness is a measure of whether or not the achievement of the goals of an organization achieves its goals. If an organization achieves its goals, it has run effectively. The research method used is descriptive research with a qualitative approach. Data collection is carried out by interview, observation, and documentation techniques. The data obtained were analyzed qualitatively with the approach to the theory of effectiveness proposed by Richard Steers, including goal achievement, integration and adaptation. This study aims to determine the effectiveness of policies and work prog

Abstract:

The content of trace elements from Crassostrea tulipa (Ostreidae, Bivalvia) from four localities (Pra Estuary, Densu Estuary, Kpone Beach, and Anyanui Creek) along the coast of Ghana has been used as a bioindicator of environmental pollution. The lowest values of heavy metals correspond to the Crassostrea shells from Densu Estuary and Anyanui Creek, whereas the highest contents are recorded in the shells from Pra Estuary and Kpone Beach. Densu Estuary and Anyanui Creek are located in areas not affected by major industries, and only Densu is located in a densely urbanized setting. Crassostrea s

Abstract:

Environmental degradation is closely related to unreasonable land use behaviors by farmers. In this study, participatory rural assessment (PRA) is used to conduct a detailed survey of farmers and plots and to collect relevant natural and social statistics. The accuracy of remote sensing data is verified by comparative analysis, and the change in status of various land use types in each research period is reflected by the change in the dynamic degree and change in range. We examine how farmers’ attitudes and behaviors affect environmental degradation, using a sample of 403 farmers in China’s Ma

Abstract:

The crystalline basement aquifer of the Pra Basin in Ghana is essential to the water supply systems of the region. This region is experiencing the ongoing pollution of major river networks from illegal mining activities. Water management is difficult due to the limited knowledge of hydrochemical controls on the groundwater. This study investigates its evolution based on analyses from a previous groundwater sampling campaign and mineralogical investigation of outcrops. The dominant reactions driving the average groundwater composition were identified by means of a combinatorial inverse modellin

Abstract:

Fishing is the most important traditional economic activity of the coastal communities in Bangladesh due to the availability of the diverse fishery resources. The Naaf River estuary is one of the large estuaries in Bangladesh coast, which plays a significant role in the socioeconomic condition of local community and considered as a major source of income through small-scale fishing. This paper highlights d the chronic problems and relative actions through sustainable management of small-scale fishermen of Naaf river.

Abstract:

Land consolidation is an effective means of promoting the regularization of fragmented arable land, optimizing the allocation of land resources and improving the environment in farming areas, as well as an important means of increasing the economic returns of farming households, and it is important to scientifically assess the ecological and economic benefits of agricultural land consolidation. In this study, participatory rural assessment (PRA) was used to investigate, in detail, the meaning, satisfaction and changes in farmland rehabilitation before and after implementation.
