Keywords: Carrying capacity, river basin, silt yeild
Abstract: Ecological Carrying Capacity provides physical limits as the maximum rate of resource usage and discharge of waste that can be sustained for economic development in the region. This provides theoretical basis with practical relevance for the sustainable development of a region. Carrying Capacity of a river basin refers to the maximum amount of water available naturally as stream flow, soil moisture etc., to meet ecological and social (domestic, irrigation and livestock) demands in a river basin. Monthly monitoring of hydrological parameters reveal that stream in the catchments with good forest (evergreen to semievergreen and moist deciduous forest) cover have reduced runoff as compared to catchments with poor forest covers.

Subject: Reclamation of Mine Regions at Bisgod Approaches and Challenges.
Keywords: Mine reclamations, Bisgod, Aprroaches and Challenges
Abstract: Mine reclamation entails restoring landscapes so as to regain its earlier ecological status. Although the process of mine reclamation occurs with the cessation of mining, planning of mine reclamation activities need to be done prior to mining in a region. This helps to provide protection and mitigate the adverse environmental impacts while improving the aesthetics of the area. Mine closure plan needs to focus on the beneficial post closure use to all stakeholders including proximate communities. Mining is a temporary use of a natural resources such as land and are disturbed by the operations that needs to be rehabilitated after completion of mining.

Keywords: Beekeeping, Sustainable Livelihood Option, Uttara Kannada, Central Western Ghats, Karnataka
Abstract: Beekeeping is a forest and agro-based industry, which is beyond the ordinary realms of industry, in the sense that the humans derive benefits from interaction between two living things like plants and bees without affecting adversely both. On the contrary plants, including many crops, prosper with abundance of bees (as pollinating agents) and the bees, sheltered both by nature and humans provide mainly honey and other by-products like beeswax, bee-pollen, propolis and royal jelly. Bee-keeping, systematically adopted as a supplement to farming, can bring prosperity to the villages of Uttara Kannada, a district endowed with species rich forests and cultivation of a high diversity crops. Unlike intensive farming or fishing that can corrode the natural resource base, abundance of honey bees in a natural environment benefits both crops and wild plants.

Subject: Adopting clustering approaches - ecology integrated sustainable development of Uttara Kannada
Keywords: Clustering approaches, Ecology Integrated Sustainable Developoment, Uttara Kannada.
Abstract: The concept of economic clustering and trade guilds in India has roots in pre-history. The cocoons and silk processing industry has traditionally existed in clusters, in places such as Banaras, Kancheepuram, Kashmir etc. Cluster-based economic development has become an increasingly popular topic for researchers and economic development professionals. The approach is considered an important aspect of a broader re-orientation of research and economic policy towards laying the foundations of a microeconomic approach for prosperity and growth. The past decades were under the spell of macroeconomics and the creation of market institutions in developing economies. While there is now fairly broad consensus on the type of macroeconomic and legal conditions neccessary to achieve economic progress, it is also becoming clearer that these conditions are not sufficient. As a new approach to help economies reap the full potential of an improved macroeconomic and legal context cluster-based efforts have recieved a potential of an improved macroeconomic and legal context cluster-based efforts have received a lot of attention. Clusters are groups of companies and institutions co-located in a specific geographic region and linked by interdependencies in providing a related group of products and/or services. Because of the proximity among them - both in terms of geography and of activities - cluster constituents enjoy the economic benefits of several types of positive location specific externalities.

Abstract: This study explores the feasibility of using airborne lidar surveys to construct high-resolution digital elevation models (DEMs) and develop an automated procedure to extract levee longitudinal elevation profiles for both federal levees in Atchafalaya Basin and local levees in Lafourche Parish, south Lousiana. This approach can successfully accommodate a high degree of levee sinuosity and abrupt changes in levee orientation (direction) in planar coordinates, variations in levee geometries, and differing DEM resolutions. The federal levees investigated in Atchafalaya Basin have crest elevations between 5.3 and 12 m while the local counterparts in Lafourche Parish are between 0.76 and 2.3 m. The vertical uncertainty in the elevation data is considered when assessing federal crest elevation against the U.S Army Corps of Engineers minimum height requirements to withstand the100-year flood. Only approximately 5% of the crest points of the two federal levees investigated in the Atchafalaya Basin region met this requirement.

Abstract: Rice is the most consumed staple food in the world and a key crop for food security. Much of the world ' s rice is produced and consumed in Asia where cropping intensity is often greater than 100% (more than one crop per year), yet this intensity is not sufficiently represented in many land use products. Agricultural practices and investments vary by season due to the different challenges faced, such as drought , salinity, or flooding , and the different requirements such as varietal choice , water source , inputs , and crop establishment methods . Thus, spatial and temporal information on the seasonal extent of rice is an important input to decision making related to increased agricultural productivity and the sustainable use of limited natural resources. The goal of this study was to demonstrate that hyper temporal moderate-resolution imaging spectroradiometer (MODIS) data can be used to map the spatial distribution of the seasonal rice crop extent and area. The study was conducted in Bangladesh where rice can be cropped once, twice, or three times a year. MODIS normalized difference vegetation index (NDVI) maximum value composite (MVC) data at 500 m resolution along with seasonal field-plot information from year 2010 were used to map rice crop extent and area for three seasons, boro ( December/January -April), aus (April/May-June/July), and aman (July/August-November/December), in Bangladesh. A subset of the field -plot information was used to assess the pixel-level accuracy of the MODIS-derived rice area. Seasonal district-level rice area statistics were used to assess the accuracy of the rice area estimates. When compared to field-plot data, the maps of rice versus non-rice exceeded 90% accuracy in all three seasons and the accuracy of the five rice classes varied from 78% to 90% across the three seasons. On average , the MODIS -derived rice area estimates were 6% higher than the sub-national statistics during boro,7% higher during aus , and 3% higher during the aman season. The MODIS -derived sub-national areas explained (R? values) 96%, 93%, and 96% of the variability at the district level for boro, aus, and aman seasons, respectively. The results demonstrated that the methods we applied for analysing and interpreting moderate spatial and high temporal resolution imagery can accurately capture the seasonal variability in rice crop extent and area. We discuss the robustness of the approach and highlight issues that must be addressed before similar methods are used across other areas of Asia where a mix of rainfed , irrigated, or supplemental irrigation permits single, double, and triple cropping in a single calendar year.

Abstract: A non-linear iterative method is used to replace the traditional spectral slope technique in initializing the total absorption decomposition model. Based on comparison of absorption coefficient by QAA and two band semi-analytical model (TSAA) models with field measurements collected from the West Florida Shelf waters and Bohai Sea, it is shown that both models are effective in estimating absorption coefficients from the West Florida Shelf waters, but the TSAA model is superior to the QAA model. Use of the TSAA model in estimating absorption coefficient in the West Florida Shelf and Bohai Sea decreases the uncertainty of estimation by 1.3-74.7% from the QAA model. The TSAA model ' s sensitivity to the input parameters was evaluated by varying one parameter and keeping the others fixed at their default values. Our results indicate that the TSAA model has quite a strong noise tolerance to addressing the field data of the total absorption coefficient.

Abstract: This paper examines the use of canopy reflectance for different units of measurements of caretenoids estimation. Field spectral measurements were collected over cotton in different intensive field campaigns organized during the growing seasons of 2010 and 2011. Three units of measurements were evaluated carotenoids expressed as a mass per unit soil surface area (g/m? ), a mass per unit leaf area (?g/cm?) , and a mass per unit fresh leaf weight (mg/g) , respectively. Four methods were compared to retrieve amount of carotenoids : stepwise multiple linear regression (SMLR) , published spectral indices , band combination indices , and partial least square regression ( PLSR) . Results show that maximum sensitivity of reflectance to variation in different units of measurement of carotenoids was found in the green region at 515-550 nm, and at 715 nm and 750 nm regions in the far-red wavelengths. The predictive accuracies of Car (g/m?) , Car (?g/cm?) and Car (mg/g) were tested on validation data set and the results show that the highest R? values between estimations and observations were 0.468 for Car (g/m?), 0.563 for Car (?g/cm?) , and 0.456 for Car (mg/g) , with relative root mean square error (RMSE% , RMSE/mean) of 48. 72%, 22.07% and 21.07%, respectively. Compared to Car (g/m?) and Car ( mg/g), the model performance indices for Car (?g/cm?) show degree of consistency among the R? values and RMSE% and MAE% values . Further comparison were performed among the estimation accuracies of different unit carotenoids and among the different approaches used in the study by a paired -t-test. The results indicate that although the best estimation results for Car (?g/cm?) and Car (mg/g) were both obtained based on PLSR , they can be estimated by all four adopted methods without significant differences (p>0.1) . Whereas for Car (g/m?) , the best estimation results were obtained based on published vegetation indices clred-edge , which were significantly better than the estimation results based on SMLR (P<0.000) . In Summary , the results of this study show that even the carotenoids expressed on concentration (mg/g) or content (?g/cm?) basis at leaf level can be estimated with the same prediction accuracies to the carotenoids expressed as a mass per unit surface area (g/m?) at canopy level using reflectance measurement at canopy level.

Abstract: For the soil moisture retrieval from passive microwave sensors, such as ESA ' s Soil Moisture and Ocean Salinity (SMOS) and the NASA Soil Moisture Active and Passive (SMAP) mission , a good knowledge about the vegetation characteristics is indispensable. Vegetation cover is a principal factor in the attenuation, scattering and absorption of the microwave emissions from the soil; and has a direct impact on the brightness temperature by way of its canopy emissions. Here, brightness temperatures were measured at three altitudes across the TERENO ( Terrestrial Environmental Observatories) Rur catchment site in Germany to achieve a range of spatial resolutions using the airborne polarimetric L-band Multibeam Radiometer 2 (PLMR2) . The L-band Microwave Emission of the Biosphere (L-MEB) model which simulates microwave emissions from the soil -vegetation layer at L-band was used to retrieve surface soil moisture for all resolutions. A Monte Carlo approach was developed to simultaneously estimate soil moisture and the vegetation parameter b ' describing the relationship between the optical thickness T and the Leaf Area Index (LAI) . LAI was retrieved from multispectral RapidEye imagery and the plant specific vegetation parameter b` was estimated from the lowest flight altitude data for crop , grass , coniferous forest , and deciduous forest. Mean values of b `were found to be 0.18, 0.07, 0.26, and 0.23, respectively. By assigning the estimated b` to higher flight altitude data sets , a high accuracy soil moisture retrieval was achieved with a Root Mean square Difference (RMSD) Of 0.035 m? m-3 when compared to ground -based measurements.

Abstract: Ground Based Interferomatric Synthetic Aperture Radars (GB-In SAR) have proved to be fully operational tools for the monitoring of ground displacement and structural deformation. The main limiting factor of the existing systems is the time to acquire a single image, typically ranging from few seconds to few minutes. This paper presents the validation and the operational use of a new system- Mimo Enhanced LInear Short SAr (MELISSA), belonging to a new class of GB-InSAR devices. MELISSA is based on a Multiple Input Multiple Output Synthetic Aperture Radar (MIMO SAR) and is capable of acquiring and processing image data at an unprecedented high speed . A configuration of the system acquiring a 0.96 m synthetic aperture and 260 m swath image in 2.6 ms was tested in a controlled environment. The results prove its ability to reach an image refreshing time smaller than 4 ms and Line-Of- Sight (LOS) displacement accuracies better than 10?m . Thus, MELISSA was able to help with the monitoring of the Costa Concordia ship movements in the immediate aftermath of grounding during both the rescue operations and subsequent wreckage removal. The accurate displacement measurements of specific points of the structure are presented in a global interferogram sequence (2-D displacement maps of the whole structure) . The collected data contributed to a precise wreck deformation reconstruction. MELISSA ' S ability to update the information almost every second has proven to be extremely reassuring as early warning on potentially catastrophic movements

Abstract: Defining pixel correspondences among images is a fundamental process in fully automating image-based 3D reconstruction . In this contribution, we show that an adaptive local stereo -method of high computational efficiency may provide accurate 3D reconstructions under various scenarios, or even outperform global optimizations. We demonstrate that census matching cost on image gradients is more robust, and we exponentially combine it with the absolute difference in colour and in principal image derivatives. An aggregated cost volume is computed by linearly expanded cross skeleton support regions. A novel consideration is the smoothing of the cost volume via a modified 3D Gaussian kernel , which is geometrically constrained; this offers 3D support to cost computation in order to relax the inherent assumption of ?fronto-parallelism? in local methods. The above steps are integrated into a hierarchical scheme, which exploits adaptive windows. Hence, failures around surface discontinuities, typical in hierarchical matching, are addressed. Extensive results are presented for datasets from popular benchmarks as well as for aerial and high-resolution close -range images.
