As the capital of the province of East Kalimantan, Samarinda City developments has a rapid progress from year to year. Samarinda City Development has a tendency oriented towards infrastructure development without regard to the existence of the quality of the existing environment. Imbalance of development in Samarinda city is to start decreasing the water catchment area, so its make increasing intensity of flood in the Samarinda City. The purpose of this study was to analyze the impact of changes in land use in the Samarinda city on the ability of the water catchment area. This research method using descriptive approach, the data collection system of primary and secondary. Intensity flood in the Samarinda city  is increasing from year to year, this condition happened as a problem that always occurs during the rainy season. Current development trends, always take an area that should be an infiltration  area for Samarinda City. Culture and inadequate infrastructure conditions such as lack of system of drainage and polder, was another factor causing the high intensity of flood  in Samarinda City. Therefore, the relevant regulations development guidelines for Samarinda  City must consider all aspects of planning, in this case especially the important of a balance of cultivated land and protected areas or zones.Keywords: Changes in land use; intensity of puddles; Samarinda

The Impact

The main sources of potential ‘organic' pollutants (essentially pathogens, nutrients, floatables, suspended solids and detergents) discharged to the Gulf of Trieste by sewers and rivers are briefly reviewed; about 470,000 people live in the coastal area, and nearly 400,000 of them discharge sewage effluents to the Gulf. This brief review is followed by an evaluation of the impact of such discharges on the quality of marine waters, with reference to the impairment of uses such as bathing and shellfish cultivation. The sanitary and aesthetic aspects of faecal pollution which typically affect coastal waters are examined together with the water quality standards pertaining to bathing waters and shellfish cultivation areas; the extent of pollution of the coastal waters is determined. Experience gained at some wastewater treatment and disposal works is cited. On the whole, the Gulf of Trieste appears to be in a satisfactory condition: more than 85% of the shoreline (totalling 42 km in Yugoslavia and 93 km in Italy) is unpolluted, according to the pertaining standards. Ameliorations are, however, urgently needed in many respects. Recommendations regarding adequate forms of sewage treatment and disposal are made.

The decline in the quality of ecosystem services in Bogor Regency is indicated by the existence of various natural disasters in recent years. Prudent development must be carried out to minimize the impact of a decrease in the ecosystem services index. The purpose of this research is to map ecosystem services for food supply, water supply, water and flood management, and tourism aspects within 2000-2017. The data used were land cover and land facet maps at a scale of 1:25,000 obtained from BIG, accompanied by a reinterpretation process. The data sources were Indonesia's topographic maps (RBI), Citra SPOT 7, DEMNAS, and field surveys. The ecosystem services index (ESI) is calculated based on an analysis of changes in land use and land facets. The value of ESI was weighted using analytic hierarchy process approaches to each of the variables assessed by experts. The results showed that the largest changes in land use occurred in residential and forest areas. The residential area increased by 1.96%, while the forest area decreased by 1.8% in 17 years. Bogor Regency is dominated by forest and rice fields which are spread over four main landforms, namely volcanic, structural, fluvial, and karst. The most significant increase of 5.65% was found in the clean water provisioning function, while the most significant decrease of 38.47% was found in the tourism and ecotourism sector. Accumulatively, the increase in ESI was 23%, while the decrease was 20.64%.  Mitigation efforts that can be done are to maintain the availability of green open space by implementing strong regulations.

The Impact

The study assessed the impact of land-use types on the groundwater quality of the mid River Njoro catchment, Kenya. Groundwater samples were collected from eight boreholes between the period of October 2017 to February 2018 and analyzed for pH, temperature, electrical conductivity, dissolved oxygen, nitrate, ammonium, and total phosphorus. These parameters were used to calculate the Groundwater Quality Index (GQI) value of the study area. The concentration maps (“primary maps I”) were constructed using Kriging interpolation of ArcGIS software from the seven groundwater quality parameters. The “primary maps I” were standardized with the KEBS and WHO standards to the “primary maps II” for ease of integration into a GIS environment. The “primary maps II” were then rated and weighted using a polynomial function to generate “rank maps” before calculating the GQI using spatial analyst tools of ArcGIS software. The land use map was prepared from a high-resolution Google earth satellite imagery of 2015. The mean GQI values for the different land use polygons were calculated and compared using GIS techniques. The GQI ranged from 68.38 to 70.92, indicating a high groundwater quality of mid River Njoro catchment. The major land-use types identified include settlement area, forest cover, agricultural land and mixed area. The agricultural land dominated the study area, followed by settlement area, forest cover and finally mixed area. The mean GQI value in each land use type varied minimally and this could be because of the diffuse nature of the land use types of the study area. Settlement area had low GQI, followed by agricultural land, mixed area and the forest cover had the highest mean GQI value, which corresponds to good quality of groundwater. Even though the variation is insignificant in this particular study, it somehow indicates the adverse effects of different land use on the quality of groundwater.

Effects Of Land Use

A ocupação extensiva e, por vezes, indevida do solo pode resultar em uma série de problemas ambientais que aceleram a degradação de uma bacia hidrográfica, com consequências diretas na qualidade dos seus recursos hídricos. Esse trabalho avalia o impacto do uso e cobertura da terra em parâmetros quantitativos e de qualidade das águas superficiais da bacia hidrográfica do rio Pirapozinho. A produção cartográfica consistiu de mapa de uso e cobertura da terra, declividade, rede de drenagem, mapa de área de preservação permanente e mapa de Índice de Qualidade da Água (IQA). Tanto a coleta quanto as análises das águas superficiais da bacia foram desenvolvidas seguindo os procedimentos do Standard Methods. Os resultados das análises foram comparados com os valores de referência CONAMA, n° 357/05, alterada pela Resolução 410/2009 e pela 430/2011, sendo os padrões estabelecidos para rios de classe 2, mesma classe que se enquadra os corpos hídricos inseridos na bacia em estudo. Conclui-se que há um desequilíbrio ambiental na bacia do rio Pirapozinho. O mapa de uso e cobertura aponta que aproximadamente 90% da área da bacia encontra-se ocupada por pastagem e culturas. Outro aspecto é que mais de 84% da área de preservação permanente encontra-se desprovida de vegetação arbórea. Embora o mapa do IQA revele que a água da bacia possa ser classificada como boa (IQA entre 52 e 79) predominantemente, as análises laboratoriais apontam que há pontos na área com contaminação. Isto pode ser atribuído a atividades industriais e agropastoris desenvolvidas na bacia em estudo. Recomenda-se ações de manejo sustentável na bacia do rio Pirapozinho para a recuperação dos seus recursos naturais. A B S T R A C TExtensive and unduly occupation of soil may result in several environmental problems those contribute to accelerate the degradation of a hydrographic basin bringing diretly consequences to quality of its water resources. This paper evaluates the impact of land use and occupation on quantitative parameters and of superficial waters quality of the hydrographic basin of the Pirapozinho river. The cartographic products designed consisted of land use and occupation map, declivitity map, drainage network map, permanent preservation area map and map of Water Quality Index (WQI) of hydrographic basin. Both collection and analysis of the superficial waters samples were developed following the Standard Method procedure. The results of the laboratorial analyses were compared with the reference values at CONAMA 357/05 and 430/11 resolutions. We conclude that there is an environmental disequilibrium at the hydrographic basin of the Pirapozinho river. The land use and occupation map shows that approximately 90% of the area of the basin is occupied by pasture and crop fields. Other finding is that there is no arboreal vegetation in 84% of the permanent preservation area of the hydrographic basin. Although the WQI map revels that water of the basin can be classified as good (WQI among 52 and 79) predominately, the laboratorial analyses point out taht there is some points in area with contamination of water. This may be related to the industrial and agricultural activities performed in the area. We recommend sustainable management actions in the Pirapozinho river basin to recovery of its natural resources.Keywords: Cartographic production; water quality; environmental analysis; hydrographic basin.

The authors aimed at showing in the publication the impact of the construction of selected water reservoirs in Poland on the surrounding environment, basing on the satellite imagery. For this purpose, for four test objects, i.e. the Dobczyce Reservoir, the Klimkow Reservoir, the Czorsztyn Reservoir and the Domaniowski Reservoir analyzes were carried out concerning the changes in the structure of land use for the state before and after reservoir construction, and indicators such as NDWI, SAVI and TSAVI were calculated. In the case of the analysis of changes in the land use structure, the direction of these changes was determined first of all, and for SAVI and TSAVI indices, the percentage change in their value and the direction of these changes were calculated.

The impact of land use on the water quality of foothill microcatchment areas The impact of land use on the water quality of foothill microcatchment areas. In this paper a comparison is made between the impact of land use methods on the quality of water in the streams which drain various catchment areas. For this purpose three microcatchments were selected which are located in agricultural, rural settlements, and forested areas. Water samples were physically and chemically analysed in order to determine: nitrates, nitrites, ammonia, phosphates, sulphates, chlorides, calcium, magnesium, dissolved oxygen, reaction and conductivity. The above studies were conducted in the 2006 and 2007. Our analysis of the collected materials allows us to affirm that land use methods have a significant impact on the water quality of the streams which drain the area. Rural settlement has the most negative influence on the water quality, followed by typical agricultural use. Based on the direct quality evaluations of single water samples, it has been found that only water from forested areas can be qualified as belonging to the 1st cleanness class.
