Research paper thumbnail of Beyond the tradition: Using Fuzzy Cognitive Maps to elicit expert views on coastal susceptibility to erosion in Bangladesh

The geomorphological characteristic of the coastal area is highly dynamic where land erosion and accretion with different rates are constant phenomena. This research focuses on three coastal zones: western, central and eastern that comprise the entire coastal area of the country. Using 'Mental Modeler' software this study quantified experts' judgements on the issue and developed FCMs by way of arranging workshops. At the basis, this study identified 33 factors of susceptibility to erosion for current baseline conditions. Considering future projections of hydro-climatic phenomena, this study accentuated potential factors of susceptibility to erosion for future scenario under three time-slices: near-future (2020), future (2050) and far-future (2080). The results generated from FCMs show that some factors such as sedimentation, soft and unconsolidated soils, shelf bathymetry, funnel shape of the Bay of Bengal, wave action, river discharge, monsoon wind, cyclone and storm surges, excessive monsoon rain, high tidal energy, variations of tidal range and sea level rise are highly influential that yielded higher centrality scores for both current and future susceptibility of the area to erosion. The experts' interpretations demonstrate that the future susceptibility to erosion might be higher in the central zone compared to the western and eastern zones of the coastal area. This is the first time that FCM based approach was applied to evaluate expert views on coastal susceptibility to erosion for 2 the country. This study suggests coastal managers, planners and policymakers to consider the current and future factors of susceptibility of coastal lands for taking specific measures options. This study is also significant from socioeconomic and demographic contexts of any densely populated coastal area like Bangladesh.

The geomorphological characteristic of the coastal areas is highly dynamic where land erosion and accretion with different rates remain a constant phenomenon. This study focuses on three coastal zones: western, central and eastern that comprise the entire coastal area of the country. At its core, this study uses the past 30 year Landsat satellite images. This research reveals that the rate of accretion in the study area is slightly higher than the rate of erosion. Overall land dynamics indicate a net gain of 237 km² (7.9 km² annual average) of land in the area for the whole period from 1985 to 2015. The results also demonstrate that the rates of both erosion and accretion are higher in the central zone compared to the western and the eastern zones of the coastal area. This is the first time that the entire coastal areas of Bangladesh have been considered for assessment. This study also recommends that coastal managers, planners and policymakers to consider the identified dynamic trends of coastal land before opting for any specific measure. Constant monitoring using the GIS and remote sensing techniques would be a viable management for this purpose. This study has identified some causes of land dynamics, particularly for the three coastal zones, that might be helpful for policymakers in identifying the nature of interventions needs to be taken for specific coastal zones.

Written at an introductory level, it explains the interacting components of this system : what the greenhouse effect is; and how scientists seek to predict climate change. It makes accessible the technical and heavy science literature to the 'non-science' student. Global warming is one of the major environmental problems facing the world today. But it is an issue surrounded by great contention because it is based largely on scientific prediction and has yet to be proven. Opinion is divided regarding whether global warming will occur and, if it does, what the effects will be. In order to appreciate the uncertainties surrounding this issue, it is necessary to understand the workings of the climate system and the methods by which scientists seek to predict climate change. 'Global Warming' aims to make accessible the heavily technical literature to the non-science student, providing a bridge between the highly scientific and the popular non-academic texts. Placing global warming within the broader context of climate change, this textbook details the interacting components of the climatic system, reviewing the importance of changing carbon dioxide levels for the evolution of the Earth's atmosphere and climate. Utilising observed and modelled data, it presents the latest evidence for and against global warming whilst highlighting the difficulties involved with analysing both types of data and introducing areas of controversy within research. The book also addresses the important problem of making policy decisions for the future, based on the uncertain science of global warming.

Research paper thumbnail of Surface-observed and satellite-retrieved cloudiness compared for the 1983 ISCCP Special Study Area in Europe

Journal of Geophysical Research, 1987

(1982). The aim of the study was to establish whether surface-observed cloud information could be usefully exploited to benefit satellite-based cloud retrievals. Observations from 124 surface stations at 1200 UT for the 20-day period from July 22 to August 10, 1983, were compared with retrievals made from METEOSAT radiances measured at 1130 UT. The comparisons for total and low-cloud amount are made for France and southern Britain. The high-cloud amount comparison was limited to 34 stations in southern Britain. The location and time period were selected to coincide with one of the regions designated for special study in the International Satellite Cloud Climatology Project (ISCCP) (Schiffer, 1982). For total cloud amount, 29% of the retrievals were fully in agreement with the surface observations and 64% of differences were within •1 okra (•1 eighth of sky cover). In the case of layer cloud amounts, 64% of the low-cloud amount differences and 50% of the high-cloud amount differences were within •1 okra, although many of these successes (71% in the low-cloud amount) were for cases of totally clear or totally cloudy skies. Surface observations, which offer the only source of accurate low-cloud amount evaluation in any multilayered situation, were found to identify thin cirrus which was not detected by the satellite retrieval and to detect small gaps in cloud decks and small clouds missed by the satellite retrieval. In addition, cloud retrievals in coastal locations seemed to be more successfully accomplished by surface observers than by the satellite retrieval algorithm used here, which does not take into account land-sea partition. 1. INTRODUCTION It has been widely recognized that the radiative properties of clouds need to be better known and understood [Global Atmospheric Research Program (GARP), 19781. To this end a new global cloud climatology is at present being compiled under the auspices of the International Satellite Cloud Climatology Project (ISCCP) [$chi•er, 1982; $chi•er and Rossow, 1983, 1985]. This will be a 5-year archive, beginning in 1983, and is being compiled from satellite data. One of the stated objectives of the research component of ISCCP is "investigation of methods to infer additional cloud properties from satellite observationsf [Rossow et al., 1985, p. 901]. In order to achieve such an objective it is first essential to establish which cloud properties are readily and successfully derivable from satellite data and which are less accessible. One approach is to compare results from a range of different cloud retrieval algorithms. Such a comparison (described by Rossow et al., [1985]) formed the basis for the construction of the ISCCP algorithm. The fact that cloud fields are three-dimensional suggests an alternative, complementary approach: comparison of surface (bottom-up) and satellite (top-down) cloud retrievals. As part of the research component of the ISCCP, a joint venture by United Kingdom and French scientists has focused on a comparison of surface observations and satellite retrievals of clouds. It must be recognized that the comparison described here tilayered, overlapping, and dynamic cloud scene. In order to capture the fullest description of clouds, the best possible approach might be the strategy adopted by the U.S. Air Force, which includes as much information as possible: surface observations, satellite retrievals and aircraft reports [Fye, !978]. On the other hand, this practice leads inevitably to heterogeneity [e.g., Hughes and Henderson-Sellers, 1985]. Another way to help resolve the dilemmas of insufficient data and ambiguous satellite retrievals is to exploit additional information or retrieval methods only where they can improve the cloud characterization substantially. One example of this is to improve cloud cover and type evaluation using statistical retrievals for selected scenes [Rossow et al., 1985]. In this paper, another question is examined: whether surface observations of clouds can be exploited to resolve ambiguities in satellite retrievals and to add lowerlayer information unobtainable from satellites. 2. DATA 5OURCES AND METhODS or COMPARISON 2.1. Location and Timing The location (France and southern Britain) and the time period studied (July 22 to August 10, 1983) were selected to coincide with one of the special study regions identified by ISCCP.

Observations for 12.00 GMT for the 20 day period 22nd July to 10th August 1983 were compared with retrievals made from }IETEOSAT radiances measured at 11.30 GET. The comparisons for total and low cloud amount were made for 204 stations covering France, southern Britain and West Germany although high cloud amount comparisons were not possible for France, so only 114 stations were used. The location and time period were selected to coincide with one of the regions designated for the validation phase of the International Satellite Cloud Climatology Project, ISCCP. The results are generally good: for total cloud amount 30% of retrievals were fully in agreement and 64% of the differences were within +1 okta. As anticipated, the surface observations offered additional information on low cloud cover in multi-layer situations. Surface observers were also found to identify thin cirrus which was not detected by the satellite retrieval and to detect small gaps in cloud decks and small clouds missed by the satellite retrieval.

Observations for 12.00 GMT for the 20 day period 22nd July to 10th August 1983 were compared with retrievals made from }IETEOSAT radiances measured at 11.30 GET. The comparisons for total and low cloud amount were made for 204 stations covering France, southern Britain and West Germany although high cloud amount comparisons were not possible for France, so only 114 stations were used. The location and time period were selected to coincide with one of the regions designated for the validation phase of the International Satellite Cloud Climatology Project, ISCCP. The results are generally good: for total cloud amount 30% of retrievals were fully in agreement and 64% of the differences were within +1 okta. As anticipated, the surface observations offered additional information on low cloud cover in multi-layer situations. Surface observers were also found to identify thin cirrus which was not detected by the satellite retrieval and to detect small gaps in cloud decks and small clouds missed by the satellite retrieval.
