Abstract To guarantee food security and job creation of small scale farmers to commercial farmers, unproductive farms in the South 24 PGS, West Bengal need land reform program to be restructured and evaluated for agricultural productivity. This study established a potential role of remote sensing and GIS for identification and mapping of salinity zone and spatial planning of agricultural land over the Basanti and Gosaba Islands(808.314sq. km) of South 24 PGS. District of West Bengal. The primary data i.e. soil pH, Electrical Conductivity (EC) and Sodium Absorption ratio (SAR) were obtained from soil samples of various GCP (Ground Control Points) locations collected at 50 mts. intervals by handheld GPS from 0–100 cm depths. The secondary information is acquired from the remotely sensed satellite data (LANDSAT ETM+) in different time scale and digital elevation model. The collected field samples were tested in the laboratory and were validated with Remote Sensing based digital indices analysisover the temporal satellite data to assess the potential changes due to over salinization. Soil physical properties such as texture, structure, depth and drainage condition is stored as attributes in a geographical soil database and linked with the soil map units. The thematic maps are integrated with climatic and terrain conditions of the area to produce land capability maps for paddy. Finally, The weighted overlay analysis was performed to assign theweights according to the importance of parameters taken into account for salineareaidentification and mapping to segregate higher, moderate, lower salinity zonesover the study area.

Abstract Background: Small-scale mining, referred to as galamsey in Ghana, is an important source of income for many rural populations. Although concerns have been raised in the media about the significant threats galamsey poses to the environment, and human health and livelihoods, there is a representational paucity of evidence regarding its links with local food systems, particularly from the perspective of affected mining communities. The current study explored community perceptions and experiences of galamsey and its perceived effects on food security and livelihoods in the East Akyem Municipality in the Eastern region of Ghana. Methods: Primary data was collected in the East Akim District of Ghana, using photography, interviews based on the photographs, and a photo exhibition, all conducted . Thirty-six male and female adults were purposively selected with the help of a community focal person and advertisements in the study community. Respondents participants in a one-day photography training and thereafter, deployed to take at least fifteen photos that portray the effect of galamsey on food security and health. Subsequently, each participant was asked to selected five of the photographs and to explain the image and why they captured that in the photo. A photo exhibition was held to facilitate community conversation and perspectives on the effects of galamsey on food and nutrition security. Results: Galamsey has resulted in degradation of, otherwise, fertile agricultural land, and contamination of freshwater sources. As a consequence, there is reduced cultivable land, reduced crop production, shortage of essential staple foods, increase in food price, and increased consumption of ultra-processed foods. There is also perception of increased exposure to heavy metals like mercury in locally-produced food. Conclusions: Given the adverse health consequences of both food and nutrition insecurity, and increased consumption of processed foods, it is important that public and policy discussions to minimize the effects of galamsey in Ghana should include considerations about food and nutrition insecurity in mining communities.

Commuting helps to keep balance between residence and workplace of workers. With growing accessibility and connectivity, the importance of commuting is increasing all over the world. It is becoming a major substitute to migration. In commute-studies, commute-pattern is an important chapter. It highlights commuters’ directions of movement, distance they cover, modes of transport they use, the time they take to commute, etc. Unlike the urban-based commute pattern, commute pattern in rural areas are relatively an under-researched issue. In fact, traditionally rural people are thought to carry a sedentary lifestyle. Using primary data, this study aims to explore the commute patterns of rural workers located in the village of Gandharbapur of Barddhaman district of West Bengal, India. All the commuters were found to be engaged in non-farm work. Commuters stem from two major groups. One group of commuters is accumulated farm-income induced. They possess sufficient agricultural land. Investing their surplus farm-income, they have established non-farm works. The second group of commuters is poverty-driven. They are landless poor or are marginal farmers and to escape poverty, they have slipped into these works. Located beyond the suburban area (Memari being the nearest town), most commuters commute to nearby rural areas. Due to non-availability of public transport, women commute less than men do. Regular-paid government employees commute longer than other workers commute. The article concludes with a summary of findings and recommendations for further research.

Agricultural productivity in the Peruvian region of Amazonas is being jeopardized by conflicts and inadequate land use, that are ultimately contributing to environmental degradation. Therefore, our aim is to assess land suitability for potato (Solanum tuberosum L.) farming in the Jucusbamba and Tincas microwatersheds located in Amazonas, in order to improve land-use planning and enhance the crop productivity of small-scale farmers. The site selection methodology involved a pair-wise comparison matrix (PCM) and a weighted multicriteria analysis using the Analytical Hierarchy Process (AHP) on selected biophysical and socioeconomical drivers. Simultaneously, land cover mapping was conducted using field samples, remote sensing (RS), geostatistics and geographic information systems (GIS). The results indicated that for potato crop farming, the most important criteria are climatological (30.14%), edaphological (29.16%), topographical (25.72%) and socioeconomical (14.98%) in nature. The final output map indicated that 8.2% (22.91 km2) was highly suitable, 68.5% (190.37 km2) was moderately suitable, 21.6% (60.11 km2) was marginally suitable and 0.0% was not suitable for potato farming. Built-up areas (archaeological sites, urban and road networks) and bodies of water were discarded from this study (4.64 km2). This study intends to promote and guide sustainable agriculture through agricultural land planning.

Seasonal migration is a common livelihood strategy among marginal and landless people of the western part of West Bengal. The National Sample Survey Organisation (NSSO) and Census data have failed to provide information on seasonal migration and livelihoods at the micro-level. The present study focuses on the nature, characteristics and factors of seasonal migration with its importance as a livelihood strategy among women agricultural labourers (WALs) in Soul Ponamara mouza of Hirbandh block at the micro-level. The study is based on primary data collection using a purposive sampling method and a semi-structured questionnaire, personal interview and focus group discussion. This study reveals that seasonal migration from Soul Ponamara to the adjacent agriculturally prosperous districts viz. Purba Bardhaman and Hooghly (4 to 6 times in a year) is a common livelihood strategy among WALs in the study area, and its proportion is almost equal to when compared to male migrants. The small size of agricultural land holding, existing monoculture system, lack of irrigation facilities, a limited job opportunity in the Soul Ponamara mouza and its surrounding area (Amjhuri, Bijardihi, Chaka Doba, Moshiara, Bamni and Rangametia) provoke women labourers to move out in searching of works. In contrast, high wage and massive demand for skilled and semi-skilled agricultural labourers during sowing and harvesting season in the destination area, that is, paddy and potato fields of Purba Bardhaman and Hooghly districts acted as a magnet to absorb these immigrants into the workforce. This study concludes that seasonal migration opted for employment and income generation is the primary livelihood strategy adopted by the rural WALs of this mouza to cope up with the existing poverty and food insecurity.

<p>The estimation of Suspended Sediment Concentration (SSC) on the surface of the Pearl River is of great significance to the management of water and soil erosion and water quality in the Pearl River. Previous studies lack of measured reflectance data and enough field samples and the distribution of sediment-concentration field samples were uneven. In response to the above problems, we combined the sediment concentration data (proceed by filtered weighing method) collected on the spot, high-precision ground measured spectral data (obtained by ASD) with multi-source remote sensing satellite images (MODIS and Sentinel-2), employing simple linear regression model (single logarithmic transformation) and neural network learning algorithm to fit the relationship model between SSC and surface reflectance (Surface Reflectance, SR). The preliminary results showed that SSC and the surface SR based on the red band (wavelength=665 nm) had a stable correlation (R2>0.83), and the red band of Sentinel 2 was appropriate for the estimation of SSC. Compared with previous studies, this study synthesized higher-precision spectrum measured data and higher-resolution remote sensing satellite data to improve the estimation accuracy of SSC. In addition, based on the SSC model under study, we will couple long-time series of satellite data to explore the spatiotemporal variation characteristics of SSC in the Pearl River, so as to provide a reference for soil erosion monitoring and water resources management in the Pearl River Basin.</p>
