Development is a changing process to improve human standard of life that strongly related to the activities of natural resource utilization. It is frequently found that these activities change the ecosystems and their resources. Eventually, these changes wil l give ser ious impacts to the envi ronments. The most distinct environmental problems are caused by resident migration to the coastal areas, coastal developments, and land limitation. Coastal reclamation is an example of human effort to respond to the land limitation in the coastal areas as observed in coastal areas of Labakkang Subdistrict. Reclamation activity is doing along the coast of Pundata Baji Village, whereas, in other villages, cutting off of mangrove areas as an alternative land expansion is increasingly practiced by the local communities. This Research was aimed to observe the landscape change from 1980 to 2010 at coast area in Labakkang Subdistrict. Each review considers Landsat Image Map (acquired in 1980); Lands...
Landscape Process: coastal area transformation
ECLAS 2014 Conference: Landscape: A Place of Cultivation, 2014
The coastal areas are characterized by land-sea transitions, which have an important role in supporting the ecosystem diversity and also human activities depending on it. However, the current evolution of urban occupation, has took place in way that jeopardized coastal ecosystems. As a contribution to collective territorial valuation, the heritage concept has evolved from putting emphasis only in a single element to value the identity of urban complexes related with the dynamics of human processes. Moreover, the landscape, as a dynamic entity, contributed to way of making the “place” based on ecological conditions and contributing for bringing back the notion of nature to man, although artificialized. This communication intends to analyze coastal dynamics of Setúbal since the 20th century, taking into account its changing occupation patterns. Enabling the assessment of a sustainable territorial evaluation by proposing an interpretation landscape model for Setúbal.
Coastal Geomorphology and Landuse Changes
2016
GOA, endowed with natural & scenic beauty, is famous for its silvery sand & golden coastline. In the recent years, a lot of changes (both natural & man-made) have occurred rapidly which have direct impact on the human environment. These changes in the nature have to be delineated for better understanding and for taking the necessary mitigate or remedial measures. Further, the management of natural resources has become a complex task as more & more socio-economic activities such as urban development, agriculture, waste disposal, nature conservation, shipping, harbor development, fisheries etc., are taking place. Present paper discusses the geomorphology of coastal features as observed and maps the land use changes that have occurred during the period from January 1999 and March 2001 due to rapid pace of urbanization, detected on the basis of field observation and with the use of IRS-1C Satellite Imageries using RS & GIS methodologies. In all, about fourteen (14) coastal features have...

The aim of the research was to analyze the influence of the natural environmental on agriculture development in mountain parts of the river valleys in semiarid areas. The research area was the upper 130 km long part of Dades valley in the Southern Morocco within High Atlas borders. Dades is one-bed river of braided type with the permanent outflow. Its drainage area consists of a lot of tributaries. In the researched area the river is supplied by several dozen tributaries but they occur only episodically. The research was carried out in 2009-2010. A special emphasis was put on the fluvial processes forming the landform of the valley bed utilized by agriculture. The processes influencing the water and soil quality are also of the key importance for agriculture development in the high mountain part of the Dades drainage basin. In order to assess the level of conversion of the river bed, which are the most intensive during the raise water stages, the structure and dynamic of the main bed in the upper part of Dades was analyzed. The research enabled to specify the features of the spatial diversity of its structure and to learn the morphodynamic function in particular parts. The alluvial fan development in the estuaries of side beds was analyzed as well (detailed geomorphologic mapping with the use of GPS RTK). The results of the measuring enabled to make three dimensional fan models and to specify the scale of the farmland areas in the bed of the Dades valley, which were covered by material from the side valleys. As a result of the research the shapes and metric features of the fans were analyzed. The shapes of pebbles transported in the beds of the side streams, in the main river bed and terraces were analyzed either. The source of the material transported in beds was specified. The comparison of the shape of material in fans and in the main valleys indicates the significant material supply from side beds. It is confirmed by the big similarity of the shape of the material in fans and the accumulative forms in the Dades river bed below these fans. The assessment of the quality from the point of view of its use for agricultural irrigation was made on the basis of chemical analysis of several dozen samples of shallow underground water and surface waters. Salinity and the basic ionic composition of the analyzed water was analyzed. On the basis of the analyses results the spatial variability of the hydro chemical features were defined. The influence of the climate factors i.e. precipitation and steaming and weathering factor in the process of forming the chemical surface water and underground river basins in mountain areas of semiarid zone was assessed. Additionally the quality of water for irrigation was assessed with the use of the most often used factor of sodium absorption (SAR) and the water electric conductivity (SEC). Hydro chemical analyses carried out in the whole Dades-Draa valley indicated that the salinity of the surface and underground water gradually increases in the lower parts of the oued. However, in the mountain part, where in lithology there are sandstones and carbonate rocks, the changes of the chemical features are not significant and connected mainly with the lithology diversity. The water of the high mountain part of the Dades river represents mainly the hydrogen carbonate – calcium and hydrogen carbonate – magnesium. The changes of the water electric conductivity in the analyzed part of the river bed are not significant and oscillate between 300 to 600 μS•cm-1. The SAR factor doesn’t exceed 2, which means that it is water of low level of sodium concentration. Taking it into account it should be stated that surface and underground water are suitable for agriculture irrigation. Only down the valley more important is not water circulation but lack of water and bigger salinity, which near Mhamid oasis has its maximal value of more than 3000 μS•cm-1. In order to specify the soil quality and salinity a detailed analysis of soil was carried out. It covered the capacity humidity measurement, electric conductivity and physicochemical features of the soil. The mineral composition was marked by the roentgen diffraction method (XRD). Soil in the terraces in Dades valley is fertile Fluvisols. On the slopes of the valley there are degraded soil. As a result the possibilities of the agriculture development are limited to the valley bed, where there meet significant difficulties connected with accumulation of the clastic material brought on the fields during the raise water stages, especially within the flood plain, middle and even upper terraces. Among the main elements of the natural environment influencing the agricultural development the most often mentioned are the quality of soil and the quality and quantity of water. The carried out researches showed however, that the much more significant problem for the river beds of high mountains in the semiarid areas are the fluvial landforming processes. The lack of water retention in the mountain parts of the valleys, many times caused by human activity, results in lack or significant degradation of the plant cover on the valley slopes. As a results the water flow in the beds of main rivers and the tributaries is rising. The faster outflow from the upper part of the basin influences not only on the size of the flow in its lower part, but also on forming of the contemporary morphodynamic of the beds. The connected with it accumulation of materials from the side beds to the main bed influence on high rate of accumulation in the lowest parts of the beds and changes in its composition. A gradual accumulation of the rock material in the oued beds results in more extensive and frequency of flooding, and then also in bigger accumulation of the material transported by the river in the flood plain, middle and even upper terraces used by local people as farmlands. As a result even up to 20% areas of farmlands are destroyed by material accumulated there.

Dynamic of the Vegetation in the Surrounding Zones of the Coastal Village of
A study about the dynamic of vegetation during the last 50 years was made in the surrounding areas of the coastal village Playa Florida, south coast of the province of Camagüey, Cuba. The information to analyze the changes of the coastal vegetation, considered those located below the lever curve of 5 m, was obtained from 1:50 000 cartographic maps of 1956 and 1977, and a satellite photo of 2010. The covered area for every type of vegetation was calculated using digital cartography tools. It was observed an increase of the mangrove area that includes mangrove, lagoons and herbaceous vegetation up to the tide line. It is explained by the fact of the displacement of the mangrove to the terrestrial zone has been higher that the backward of the coastal line, mainly due to the natural sinking of the marine platform and the erosion produced in the beach by human activity.
The Effect of Topography on Settlement Patterns in The Nusa Penida Island, Bali, Indonesia
International Journal of Modern Agriculture, 2021
Nusa Penida Island's physical condition is an area with dry, calcareous, and steep topography, valley also hilly. Nusa Penida Island consists of 16 villages scattered in clusters in the northern and southern regions with coastal and hilly areas. The settlements in the south of the part have an organic settlement pattern following the pattern and height also the type of soil from the topography of the area. This research aimed to examine the topographical aspects of villages' settlement patterns in the southern part of Nusa Penida Island. The method used in this research is qualitative content analysis through an approach to the content aspects of studies on Nusa Penida, empirical conditions, and aerial photography analysis. The sample selection was limited by purposive sampling to two villages, namely Tangled Village and Batukandik Village. The results of this study indicate that there is a harmonious and integrated relationship between settlements and land: (1) the zone of worship (shrines/temples) and residential zones of houses; (2) rocky soil type as an option in residential construction; (3) soil layer with minimal rock content as an alternative to agricultural land; and (4) have an organic settlement pattern..
