Abstract: The present study was conducted to characterize carbohydrate and protein fractions in Phalaris minor seeds (a novel feedstuff) in comparison to conventional energy sources fed to livestock. The crude protein of P. minor seeds was similar to wheat and was higher (P<0.05) than other conventional cereal grains evaluated. P.minor seeds recorded the highest (P<0.05) level of ether extract, total ash, lignin, neutral and acid detergent insoluble protein. P.minor seeds had lower (P<0.05) level of total carbohydrates than conventional cereal grains. Wheat grains exhibited highest (0<0.05) level of non-structural carbohydrates followed by maize, P.minor, pearl millet and barley. Proteins fractions PB1 and PB2 in P.minor seeds were similar to maize. Total digestible nutrients in P.minor seeds were higher Total digestible nutrients in P.minor seeds were higher (P<0.05) than pearl millet and barley. P.minor seeds could be considered as promising energy supplement for livestock as indicated by its chemical conditions.

Abstract: Obstacle avoidance and navigation is a demanding task for an autonomous underwater vehicle (AUV) due to the complex nature of the underwater environment. However, an automatic detection and tracking system is the primary element for an AUV or an aqueous surveillance network. Tracking underwater objects in an active context represents an ongoing challenge in the field of signal processing. In order to detect the target ' s presence under water, the echoes reflected by that target are analysed by the receiver. Track accuracy is one of the paramount performance measures of tracking system. Towards this, various methods such as Kalman filter (KF), extended Kalman filter (EKF) and least squares (LS) have been explored. However, all these methods have their own drawbacks. In this study, a new approach called modified gain EKF has been implemented on the simulated data for tracking of underwater moving object using bearing and elevation measurements.AUV fitted with a single sonar is used for validating the proposed bearing and elevation only tracking (BEOT) algorithm. The performance of the algorithm is evaluated in Monte Carlo simulations and results are presented in stipulated geometries.

Abstract: Using data from a household survey of 2660 farm-families in Bihar state of Eastern India, Terai of Nepal and coastal Bangladesh, we explore the significance climatic and non-climatic factors in affecting farmers ' decision to change their farming practices over time in a wide range of environments. We find evidence across all sites, irrespective of rainfall and climatic stresses, that market-related forces (such as higher yields and better market opportunity) and resource issues (such as declining fertility, labour shortage and biotic factors) have been a strong driver changes in farming practices over the last ten years relative to climatic factors. Food sufficient households are likely more adaptable to a changing climate, as they are undertaking new agricultural practices. The results suggest that social protection measures aimed at enhancing the food security situation of marginal and smallholder households will increase the likelihood of them being in a better position to innovate and adopt improved agricultural practices. Our findings also indicate that additional strategies and policies aimed at more widespread uptake of new agricultural practices will also be needed, and will have to be targeted to particular environments and vulnerable groups, and special attention to institutional, resource management and market development issues if they are to succeed.

Abstract: This study evaluates the impacts of climate change on maize yields in Tamil Nadu, and assesses the efficacy of adaptation strategies, using a novel multi-climate, multi-crop model approach based on AgMIP Protocols (www.agmip.org).While the climate models displayed consistent changes to rainfall and temperature, substantial uncertainty exists between the different climate-crop model responses that warrant further study. Adaptation strategies proved beneficial under current climate context, but showed diminished efficacy under future climate conditions. We recommend that future work focus on identifying the main sources of climate-crop model uncertainty, and that additional work may focus on more transformative adaptation measures.

Keywords: Adoption, climate change, laser land leveling, rice-wheat system, zero-tillage.
Abstract: Small landholders can implement a range of climate-smart agricultural (CSA) practices and technologies, in order to minimize the adverse effects of climate change and variability, but their adoption largely depends on economic benefits associated with the practices. To demonstrate the potential economic benefits of CSA practices, we conducted a study with smallholder farmers in the Indo-Gangetic Plains (IGP) of India. Among the CSA practices and technologies including use of improved crop varieties, laser land leveling, zero tillage, residue management, site specific nutrient management, and crop diversification, a majority of the farmers prefer to use improved crop varieties, crop diversification, laser land leveling and zero tillage practice. We estimated the cost of adoption, change in yields and income for the implementation of three major CSA practices in rice-wheat system. The average cost of adoption were +1, 402, +3, 037 and -1, 577 INR ha-1 for the use of improved crop varieties, laser land leveling and zero tillage respectively. Results show that farmers can increase net return of INR 15, 712 ha-1yr-1 with improved crop varieties, INR 8, 119 ha-1yr-1 with laser leveling and INR 6,951 ha-1yr-1 with zero tillage in rice-wheat system. Results also show that the combination of improved seeds with zero tillage and laser land leveling technologies can further improve crop yields as well as net returns. The econometric analysis indicates that implementations of CSA practices and technologies in smallholder farms in the IGP of India have significant impacts on change in total production costs and yield in rice-wheat system.

Abstract: It is imperative to understand the effects of climate change on household members and the vulnerability level in and across agricultural households for India in general, and for eastern coastal part of the country in particular. This study covers primary data from 150 households from 2 blocks of Kendrapara district in Odisha. The household level unit of analysi is policy driven and follows the IPCC model on Vulnerability Analysis and Climate Change Adaptation Research. The model is expanded to include the livelihood strategies of the households, in order to empirically assess their vulnerability and adaptive responses. This study uses an econometric model on household vulnerability and adaptive capacity of rural households. The results imply that access to credit facilities and experiences of the households in farming are important factors to improve farmers ' adaptation to climate change.

Abstract: Vulnerability of communities and natural ecosystems, to potential impacts of climate change in developing countries India, and the need for adaptation are rapidly emerging as central issues in the debate around policy responses to climate change. The present study presents an approach to identify and prioritize the most vulnerable districts, villages and households in Karnataka State, through a multi-scale assessment of inherent vulnerability to current climate variability. It also identifies the drivers of inherent vulnerability, thereby providing a tool for developing and mainstreaming adaptation strategies, in ongoing developmental or dedicated adaptation strategies, in ongoing developmental or dedicated adaptation programmes. The multi-scale assessment was made for all 30 districts at the state level in Karnataka, about 1220 villages in Chikballapur district, and at the household level for two villages-Gundlapalli and Saddapalli-in Bagepalli taluk of Chikballapur district. At the district, village and household levels, low levels of education and skills are the dominant factors contributing to vulnerability. At the village and household level, the lack of income diversification and livelihood support institutions are key drivers of vulnerability. The approach of multi-scale vulnerability assessment facilitates identification and prioritization of the drivers of vulnerability at different scales, to focus adaptation interventions to address these drivers.

Abstract: Adaptation strategies that can minimize the negative effects of climatic risk were implemented in over 2000 farms in 12 villages of Mewat district in Haryana, India. Detailed household (HH) level data from 120 farm families for two periods (prior to intervention and end of project period) indicated: (i) agricultural profit of adapted farmers was more than that of non-adapted farmers in all strata according to the difference in difference model; (ii) non-adapted farmers in <4 acre groups have to either alter the existing agricultural practices to reduce management cost and increase profit or incur additional cost for adaptation; (iii) large farmers may have to rationalize their management investments for gaining more profits; (iv) the profit is not directly proportional to the cost of adaptation, if any, among different strata of farmers; (v) agricultural income alone cannot sustain small and marginal farm (<4 acre) families, however with adaptation a self-sustaining agriculture could be achieved; (vi) suitable adaptation can reduce the cost of farm operations, and increase agricultural profits as well as adaptive capacity to climatic risks; (vii) additional cost is not always required for adaptation, and rationalizing agricultural expenditure is essential to adapt to climatic risks. At community level differential costs of adaptation and profits are likely. Policies for incentivizing these ' responsive adaptation ' costs for small and marginal farmers would be required. However, in-vestments may be required for establishing permanent agricultural-infrastructure for managing water and agricultural produce in order to sustain agricultural profitability.

Abstract: One of the primary drivers of climate change has been the continuous increase in anthropogenic greenhouse gas emissions. If these emissions continue to increase at the current rate then it would push the carbon cycle out of its dynamic equilibrium which may lead to irreversible changes in the climate system. Thus, it is imperative to initiate systematic changes through various socio-economic and technological interventions to mitigate emissions and enhance sinks. This paper attempts to present a conceptual framework of such interventions and highlights the synergies between mitigation and adaptation.

Keywords: Adaptation, central India, climate change, resilience, rural livelihood.
Abstract: Resilience has moved from being a peripheral ecological concept to a central goal, in the development discourse. While the concept has become popular, operationalizing resilience has been difficult. Many frameworks have been proposed to operationalize resilience but no common framework has been agreed upon. The present article demonstrates a step by step method to operationalize livelihood resilience analysis, for communities that are affected by climate change by taking the case of rural household livelihoods in villages around Ratapani Wildlife Sanctuary in Central India. The article combines the Sustainable Livelihood Framework (SLF) with the Cross Scale Resilience Analysis (CSRA), as a way to operationalize resilience. The CSRA is found to be simple, systematic and applicable in diverse contexts. The systematic and holistic asset, process and institution-based analysis under the SLF, supports the CSRA by defining the system and identifying associated important shocks that affect the system. Through the analysis, it was realized that the impact of shifts in government policies on rural livelihoods is much greater than the impacts of climate change. The livelihood is worst affected when the shift in government policies coincides with impacts of climate change. The article argues that combining the SLF with the CSRA can provide a standardized method for livelihood resilience analysis of poor natural-resource dependent communities in developing countries. Handling the dynamic nature of these complex adaptive social-ecological systems in the resilience analysis should be the next goal to tackle.

Abstract: In developing countries, the major role of agricultural extensions is to disseminate farm technologies developed by the public funded research organizations, through demonstrations, field visits and farmers ' meetings or through media and others. Earlier, the extension personnel were involved in technology diffusion, but in the last two decades, the nature of agricultural technology design and integration is drawing attention of the extension professionals and practitioners across the globe. In India, different models for transfer of farm technology have been tested and also robust extension education approaches have been validated. Furthermore, the frontline extension system of the country has been sharpened through more farmer-centric approaches for technology adaptation and dissemination. Globally too, the adjustment in public extension system is seen. Using China and USA as case studies, we highlight the changes the public extension system has undergone. The operational paradigm of the country ' s extension system has been suggested to move beyond technology and beyond commodity through ensured reciprocal farmer-research-extension linkages.

Abstract: An estuary is a region where a river meets the sea. In these estuarine regions three exists a strong physico-chemical and compositional gradient in the water properties that varies rapidly from freshwater to sea water. Estuaries are important areas as they filter out suspended particulate matter (SPM), sediments and pollutants from the rivers before entering the sea and keep the coastal seas healthy. The concentration of SPM varies from river end to sea end of the estuary, and high SPM concentrations along the transect are controlled by several factors, including the action of tides, gravity circulation, density stratification, resuspension and flocculation, or due to the combined action of one or more of these forces.

Abstract: Rivers provide ecological and socio-economic benefits despite being highly threatened ecosystems. They continue to face anthropogenic and natural stresses. The aglar in the Indian Himalaya is an important tributary of the Yamuna River, and hosts the annual ' fish-festival ' of the region. Field studies have revealed that this festival could harm endemic/threatened fish species of the Aglar. Lethal methods such as the use of bleaching powder and electricity should be banned; instead angling and cast netting in a regulated way could be promoted.
