Pattern diversities in cropping systems in tribal regions: a case study of Jhabua tribal district in Madhya Pradesh, India

Agricultural development has been analysed by studying the cropping pattern and cropping diversification and crop specialization in any agro-ecosystem in regional and temporal framework. Tribal regions are experiencing agricultural intensification through diversification of cropping systems and crop specialization as a result of ecological economic changes as well as impact of public policy of technology transfer and resource use intensification. The market forces also are influencing the crop intensification as a result of exogenous market demand. In this paper, an attempt is made to analyze the pattern of cropping system in inter regional framework and identify how these patterns have changed over a period of time in Jhabua tribal district of Madhya Pradesh. Such an analysis will help in taking policy decisions for diversification and specialization of crop production in the changing cropping systems in regional framework with the objectives of achieving higher level of regional food production, maximisation of production and income to the farmers through promotion of cash crops etc. The analysis of the pattern diversity in regional framework would indicate to the eco-regional and exogenous impacts of market and public policies following the law of entropy.Cropping pattern, diversification, tribal regions

Pattern Identification of Land use and Resource use efficiencies in Agriculture in Jhabua Tribal district in Madhya Pradesh

In the fifties and sixties of 20th century, the regional economists identified a regional process of circular and cumulative causation of under- development of resource-rich but backward regions (Myrdal) and core-periphery relation of developed industrial regions with resource hinterland regions (Friedman). In the seventies, environment and development conflicts were identified leading to ecological and socio-economic degradation in the resource regions. In the regional framework, the tribal regions as sub-national regions have come under serious anthropogenic impacts due to increasing demands for resource materials for trade and industries. Growing awareness of environmental degradation and depletion, the policy makers, planners, environmentalist and economists have focused their attention to examine the efficiencies of land use and the resource use in agriculture, identifying the ecological and economic efficiencies of the resource use pattern. Agriculture, being an organic economic activity, has a close relation with the natural resources like land and water. The tribal ecology is changing and the tribes have gradually adapted to agriculture activities and a distinct agro-ecosystem has grown in tribal areas. The tribes are trying to diversify the resource use for their ecological and economic sustenance. The government is also influencing resource use and land use as development strategy in the tribal region. It is necessary to examine the land use and the resource use efficiencies in the agricultural areas in regional and temporal framework. Land use and resource use efficiencies have been measured to evaluate ecologic and economic efficiency and growth in agriculture. Since, agriculture operates in system dynamic framework in which agriculture has close relation with other uses like forestry in ecological landscape in eco-regional framework and is affected by climatic change and other anthropogenic impacts resulting from industrialization and urbanization. it is necessary to identify the land use and resource use efficiencies in agriculture in the tribal eco-system. Along with land, other natural resources like water are important in agriculture. The efficiency of irrigation may be an indicator to identify the use of water resource and its efficiency in agriculture. The land use and irrigation intensity are used as an indicators for measuring land use and resource use efficiency in this study. In this paper, the land use intensity has been measured by (1) Analysis of the land use extension in agriculture in different tahsils of Jhabua district to identify the level of resource use in different regions. (2) The land use and irrigation intensity has been used as measure of resource use intensity and efficiency in different tahsils in study area (3) The agricultural land use efficiency has been measured using standard coefficient, which is a modified Kendall’s Ranking Coefficient method for agricultural land use zoning based on land use efficienciesPattern identification, land use and resource use efficiency, Kendall's Ranking coefficient

Agricultural development and regional carrying capacity measurement of agro-ecosystem in Jhabua tribal district in Madhya Pradesh

The agro-ecosystem is a system composed of population, natural resources and economic activities related in a dynamic interaction in terms of socio-ecological and socio-economic relations conditioned by endogenous and exogenous factors. With time, the agro-ecosystem undergoes changes. By analysing the agro-ecosystem dynamics over a period of time, we can plan the agro-ecosystem for higher level of production and productivity, achieving higher level of resource use and environmental efficiency and maximise food security as well as livelihood security. Due to the control of forest area by the government, the tribes are largely depending on agriculture. Jhabua district is tribal dominated with almost 86.84 percent tribal population of approximately 14 lakhs by 2001 Census. The geographical area of the district is 6793 sq. km. The net cultivated area is in the district is 64 percent to the total geographical area. The Jhabua district is located in the western part of Madhya Pradesh on the spur of the Vindhyas and along the western boundry of the Malwa plateau. It adjoins by Banswara district of Rajasthan in Northwest, by Panchmahal and Barodra district of Gujrat in the west, Dhulia district of Maharastra and West Nimar district of Madhya Pradesh in south, Dhar district in the east and Rutlam in the west. The Carrying capacity of agricultural ecosystem may be measured by taking production, productivity and socio-ecologic criteria. Food security, production and food availability and population and employment are used as indicators for measuring the carrying capacity of any agro-ecosystem. The carrying capacity measurement is important to check the capacity of the agro-ecosystem to support the population, the productivity changes of the ecosystem and food availability and other measures. In this paper, an attempt is made to analyse the adaptation of tribal population to agriculture and changes taking place in the agro-ecosystem and its productivity. It is necessary to identify population change, its density and spread, changes taking place in habitat in terms of land use changes and population and agro-ecosystem linkages in terms of landholding, population carrying capacity, food security, employment condition etc. Such an analysis would help to undertake agricultural development food security and employment security in the tribal regions with the objectives of eco-restoration, conservation and development.Population carrying capacity, ecosystem productivity, food security

Synchronous-Clock, One-Way-Travel-Time Acoustic Navigation for Underwater Vehicles

This paper reports the development and deployment of a synchronous-clock acoustic navigation system suitable for the simultaneous navigation of multiple underwater vehicles. Our navigation system is composed of an acoustic modem–based communication and navigation system that allows for onboard navigational data to be broadcast as a data packet by a source node and for all passively receiving nodes to be able to decode the data packet to obtain a one-way-travel-time (OWTT) pseudo-range measurement and navigational ephemeris data. The navigation method reported herein uses a surface ship acting as a single moving reference beacon to a fleet of passively listening underwater vehicles. All vehicles within acoustic range are able to concurrently measure their slant range to the reference beacon using the OWTT measurement methodology and additionally receive transmission of reference beacon position using the modem data packet. The advantages of this type of navigation system are that it can (i) concurrently navigate multiple underwater vehicles within the vicinity of the surface ship and (ii) provide a bounded-error XY position measure that is commensurate with conventional moored long-baseline (LBL) navigation systems [i.e., ] but unlike LBL is not geographically restricted to a fixed-beacon network. We present results for two different field experiments using a two-node configuration consisting of a global positioning system–equipped surface ship acting as a global navigation aid to a Doppler-aided autonomous underwater vehicle. In each experiment, vehicle position was independently corroborated by other standard navigation means. Results for a maximum likelihood sensor fusion framework are reported.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/86046/1/reustice-2.pd

Seasonal, annual and inter-annual features of turbulence parameters over the tropical station Pune (18°32' N, 73°51' E) observed with UHF wind profiler

The present study is specifically focused on the seasonal, annual and inter-annual variations of the refractive index structure parameter (Cn2) using three years of radar observations. Energy dissipation rates (ε) during different seasons for a particular year are also computed over a tropical station, Pune. Doppler spectral width measurements made by the Wind Profiler, under various atmospheric conditions, are utilized to estimate the turbulence parameters. The refractive index structure parameter varies from 10−17.5 to 10−13 m−2/3 under clear air to precipitation conditions in the height region of 1.05 to 10.35 km. During the monsoon months, observed Cn2 values are up to 1–2 orders of magnitude higher than those during pre-monsoon and post-monsoon seasons. Spectral width correction for various non-turbulent spectral broadenings such as beam broadening and shear broadening are made in the observed spectral width for reliable estimation of ε under non-precipitating conditions. It is found that in the lower tropospheric height region, values of ε are in the range of 10−6 to 10−3 m2 s−3. In summer and monsoon seasons the observed values of ε are larger than those in post-monsoon and winter seasons in the lower troposphere. A comparison of Cn2 observed with the wind profiler and that estimated using Radio Sonde/Radio Wind (RS/RW) data of nearby Met station Chikalthana has been made for the month of July 200
