Abstract: The present study assessed climate change vulnerability in agricultural sector of low-lying Sagar Island of Bay of Bengal. Vulnerability indices were estimated using spatially aggregated biophysical and socio-economic parameters by applying principal component analysis and equal weight method. The similarities and differences of outputs of these two methods were analysed across the island. From the integration of outputs and based on the severity of vulnerability, explicit vulnerable zones were demarcated spatially. Results revealed that life subsistence agriculture in 11.8% geographical area (2829 ha) of the island along the western coast falls under very high vulnerable zone (VHVZ VI of 84–99%) to climate change. Comparatively higher values of exposure (0.53 ± 0.26) and sensitivity (0.78 ± 0.14) subindices affirmed that the VHV zone is highly exposed to climate stressor with very low adaptive capacity (ADI= 0.24 ± 0.16) to combat vulnerability to climate change. Hence, food security for a population of >22 thousands comprising >3.7 thousand agrarian households are highly exposed to climate change. Another 17% area comprising 17.5% population covering 20% villages in north-western and eastern parts of the island also falls under high vulnerable (VI= 61%–77%) zone. Findings revealed large spatial heterogeneity in the degree of vulnerability across the island and thus, demands devising area specific planning (adaptation and mitigation strategies) to address the climate change impact implications both at macro and micro levels.

TL;DR: The present study highlights the adaptive capacity of crop planning including abiotic stress-tolerant cultivars to monsoon rainfall variability for sustaining rainfed rice production vis-à-vis food and livelihood security in vulnerable islands of coastal ecosystem.
Abstract: In the Sagar Island of Bay of Bengal, rainfed lowland rice is the major crop, grown solely depending on erratic distribution of southwest monsoon (SM) rainfall. Lack of information on SM rainfall variability and absence of crop scheduling accordingly results in frequent occurrence of intermittent water stress and occasional crop failure. In the present study, we analyzed long period (1982–2010) SM rainfall behavior (onset, withdrawal, rainfall and wetness indices, dry and wet spells), crop water requirement (CWR, by Food and Agriculture Organization (FAO) 56), and probability of weekly rainfall occurrence (by two-parameter gamma distribution) to assess the variability and impact on water availability, CWR, and rice productivity. Finally, crop planning was suggested to overcome monsoon uncertainties on water availability and rice productivity. Study revealed that the normal onset and withdrawal weeks for SM rainfall were 22nd ± 1 and 43rd ± 2 meteorological weeks (MW), respectively. However, effective monsoon rainfall started at 24th MW (rainfall 92.7 mm, p > 56.7 % for 50 mm rainfall) and was terminated by the end of 40th MW (rainfall 90.7 mm, p 7 days in duration and reflected a significant (p < 0.05) increasing trend (at 0.22 days year−1) over the years (1982–2010). The present study highlights the adaptive capacity of crop planning including abiotic stress-tolerant cultivars to monsoon rainfall variability for sustaining rainfed rice production vis-a-vis food and livelihood security in vulnerable islands of coastal ecosystem.

TL;DR: In this paper, a set of relevant morphodynamic variables like rainfall, discharge, groundwater, geology and soil, and also human factors have been considered for understanding the nature of river bank erosion.
Abstract: River banks are multifaceted earth-forms where different geomorphic processes act together in a complex manner. River bank erosion is an episodic event by which an unstable bank tries to reach into a stable one. This is very common in deltaic meandering river systems. The River Ichamati, located in the eastern part of the Ganga delta region, is susceptible to severe bank erosion. This is because of its diurnal and seasonal fluctuation in the tide-dominated discharge, which is favoured by its channel geometry and local land use. The present paper is based on filed level observations and measurements followed by analysis with reference to theoretical perspectives of channel morphometry as provided by renowned scholars in the field. A set of relevant morphodynamic variables like rainfall, discharge, groundwater, geology and soil, and also human factors have been considered for understanding the nature of river bank erosion.

TL;DR: In this paper, the authors examined the role of man as an important controlling element of a river system and examined the human interventions over river, as a control system, and discussed about the associated changing characters of river behaviour as the response, e.g. longitudinal profile has been changed temporally due to human impact; cross profiles have been changed due to the impact of bridge and other human influences; and the tidal discharge of the river has been altered downstream upward due to intake of water for different purposes.
Abstract: With the advancement of human civilization, the river cascading system has been converted into a control system and man has a significant role in it. This paper has examined how the rivers, flowing across the highly populated Ganga–Brahmaputra Delta, are being obliterated due to the close contact of human civilization, as is an example of Ichamati River, an important distributary channel in the district of North 24 Parganas, India. The Ichamati River drains the east and south sides of the North 24 Parganas district and is covered by deep Quaternary sediments produced under tropical monsoon climate in India. The district is densely populated. GIS and a detail field investigation along with two case studies have been incorporated to extract the relationship between man and river, as a control system. This study significantly will draw the attention how the river has modified itself against imprudence human attitude towards environment without any proper river management. This paper has examined the human interventions over river, as a control system, and has discussed about the associated changing characters of river behaviour as the response, e.g. (1) longitudinal profile has been changed temporally due to human impact; (2) the characters of cross profiles have been changed due to the impact of bridge and other human influences; (3) the tidal discharge of the river has been changed downstream upward due to intake of water for different purposes. The primary objective of this article is to examine the role of man as an important controlling element of a river system.

TL;DR: In this paper, remote sensing and geographic information system techniques in assessing groundwater potential zones by the manipulation and analysis of the individual layer of spatial controlling data in a part of Deccan Volcanic Province, Maharashtra.
Abstract: This article deals with the remote sensing and geographic information system techniques in assessing groundwater potential zones by the manipulation and analysis of the individual layer of spatial controlling data in a part of Deccan Volcanic Province, Maharashtra. Available geology, geomorphology, and soil maps were collected. Land use and land cover (LULC) and Lineament maps had been prepared using the LANDSAT-8 (TM and OLI) Satellite Image (November 2015). The SRTM DEM (resolution: 30 m) data had been employed for the preparation of slope and drainage maps. These maps were converted into the raster format. Analytic hierarchy process was applied to weight, ranking, and reclassify these maps in the ArcGIS version 10.4. Then, groundwater prospect map had been prepared by overlaying the maps. The results show that five groundwater potential zones such as very poor (11.77%), poor (21.73%), moderate (30.13%), good (25.34%), and very good (11.02%) exit. Sensitivity analysis reveals that the lineament density, LULC, and slope increase the area slightly only in the very poor to poor potential zones. Besides, the well yields, groundwater level fluctuation corresponding rainfall data had been utilized to validate. The yield values vary from 5.94 to 14.88 l/s in the good to very good potential zones, whereas 0.38 to 1.37 l/s within the poor to very poor potential zones. In addition, cross-correlation coefficients among groundwater level and rainfall is well-related to the groundwater potential index (R2 = 0.84), which will help to construct artificial recharge structures and the planning of sustainable groundwater management.

TL;DR: In this article, the authors trace some key elements of the neoliberal approach to housing and its impact on the enjoyment of the right to housing in different contexts and times, taking the World Bank's 1993 manifesto as a starting point and the subprime crisis as its first great international flashpoint.
Abstract: Over the last few decades we have witnessed a global U-turn in prevailing housing and urban policy agendas, spread around the world by the driving forces of globalization and neoliberalism. The new paradigm was mainly based on the withdrawal of states from the housing sector and the implementation of policies designed to create stronger and larger market-based housing finance models. The commodification of housing, together with the increased use of housing as an investment asset within a globalized financial market, has profoundly affected the enjoyment of the right to adequate housing. Taking the World Bank's 1993 manifesto as a starting point and the subprime crisis as its first great international flashpoint, this essay traces some key elements of the neoliberal approach to housing and its impact on the enjoyment of the right to housing in different contexts and times. The reform of housing policy — with all its components of homeownership, private property and binding financial commitments — has been central to the political and ideological strategies through which the dominance of neoliberalism is maintained. Conversely, the crisis (and its origins in the housing market) reflects the inability of market mechanisms to provide adequate and affordable housing for all.
