The non conventional energy has derived mainly from the biomass which is utilized towards the sector of rural economy. The North-East India has consumed in from firewood cow dung and crop residues are used for gas production and it can replace much other energy oil from biogas production. The economic analysis of biogas plants has showed that the installation of biogas is economically very important. This paper throws light on the techniques of biogas production and its use in North-East India.

Guwahati derives its name from the Assamese word “Guwa” means areca nut and “Haat” means market. However, the modern Guwahati had been known as the ancient Pragjyotishpura and was the capital of Assam under the Kamrupa kingdom. A beautiful city Guwahati is situated on the south bank of the river Bramhaputra. Moreover, It is known as the largest city in the Indian state of Assam and also the largest metropolis in North East India. It has also its importance as the gateway to the North- East India. Assamese and English are the spoken languages in Guwahati.  In 1667, the Mogul forces were defeated in the battle by the Ahom forces commanded by Lachut Barphukan. Thus, in a sense Guwahati became the bone of contention among the Ahoms, Kochas and the Moguls during the medieval period.  Guwahati the administrative headquarters of Lower Assam with a viceroy or Barbhukan was made by the Ahom king.  Since 1972 it has been the capital of Assam. The present paper will discuss the changes happened in Guwahati over the period of late 1970s till the present time. It will focus on the behavior of people, transformed temples, Panbazar of the city, river bank of Bramhaputra, old Fancy Bazaar, chaotic ways, festivals and seasons including a fifth man made season etc. It will also deal how over the years a city endowed with nature’s gifts and scenic views, has been changing as “a dirty city”. Furthermore, it will also present the insurgencies that have barged into the city. The occurrence of changes will be discussed through the perspective and point of view of Srutimala Duara as presented in her book Mindprints of Guwahati.

In India, higher education is a need of hour. The excellence of Higher Edification decides the production of skilled manpower to the nation. Indian education system significantly teaching has not been tested too economical to form youths of our country employable in line with the requirement of job market. Despite the rise in range of establishments at primary, secondary and tertiary level our young educated folks don't seem to be capable of being used and recovering job opportunities. Reason being they need not non-heritable such skills essential for demand of the duty market. The present study is aimed at analyzing the status of higher education institutions in terms of Infrastructure, various courses of the institute, quality Initiatives and skill development program offered by the Institutes, in the North-East India region, so as to see whether the Higher Educational Institutes of this region are in the process of gradually developing the skills of the students in attaining excellence. The paper also laid emphasis on the measures adopted by these institutes for quality improvement, and to find out their role in combating the adversity acclaimed in the region, since this region’s development is impeded by certain inherent difficulties However, this paper focuses attention on high quality education with special emphasis on higher education for forward linkages through value addition.

The study used a large farm household level data to assess the economic impact of crop diversification and also identifies the factors influencing the extent of diversification in the north east region of India. The crop sector was found to be skewed towards specialization. The result of instrumental variable technique showed that crop diversification has a positively significant impact on the income among the households. Further, fractional logit estimation found that variables like family members in the working age group, landholding size, crop loss experience, extension contact, participation in training positively affected diversification. Irrigated area, access to institutional credit, etc negatively affected the same. Diversification towards high value crops may accelerate the agricultural growth of the region and improve the wellbeing of the farmers. Measures for improvement of basic infrastructural facilities and extension services for improving backward and forward linkages are required.

The Sergipe-Alagoas Basin, situated in the north-east Brazilian margin, has a long tradition of oil and gas production and the presence and distribution of evaporites play an important role in petroleum systems in the basin. However, little research has focused on the structural evolution of the older, synrift evaporitic sections of the basin. We have focused explicitly in the detailed subsurface structural characterization of the rift in the Alagoas subbasin and the distribution of the Early Aptian evaporites. To accomplish this objective, we interpreted selected 2D and 3D seismic and well data located in two areas known as the Varela Low (VL) and Fazenda Guindaste Low (FGL). We identified diverse deformation styles in those two basin depocenters. Our interpretation indicates that VL consists of a half-graben with a significant rollover structure, controlled by two listric northeast–southwest border faults. The deformation in the hanging wall is also accommodated by release faults and minor antithetic faults. In this depocenter, we mapped in the seismic and the well data an older evaporitic sequence within the Coqueiro Seco Fm., known as Horizonte Salt. This evaporitic section occurs in the internal part of the VL half graben, where it is limited by release and antithetic faults. Significant salt strata growing toward the antithetic fault is observed. Whereas, the FGL represents a graben elongated along the north-east direction and is controlled by several types of structures. We recognized normal synthetic and antithetic faults, transfer zones, release faults, and rollover anticlines in the seismic throughout this depocenter. We mapped an evaporitic section within the Maceió Fm., known as Paripueira Salt, which consists of disconnected salt bodies, restricted to the hanging walls of synrift faults.

Most rural people in Kenya rely principally on human and animal muscle power in their work as subsistence farmers, herdsmen, fisherman, or small-scale crop farmers. All the agricultural processes (ranging from ploughing to harvesting) are done largely by hand, with some help from draft animals and simple tools. Firewood is their principal cooking and heating fuel while kerosene in used for lighting. Their economic growth is hence blocked by the energy crisis. Due to their heavy dependence on biomass – mainly firewood, crop residues, and animal dung – they deprive the soil of essential nutrients and pose a threat to the agricultural lands due to deforestation and the resulting soil erosion. The problem of rural energy, therefore places the provision of food and other basic needs at risk. A technology which extracts a more useful and convenient form of fuel from biomass without destroying its fertilizer value than the traditional conversion method of direct combustion is highly desirable. Anaerobic digestion of agricultural residues generates biogas which can be used directly for lighting, cooking, electricity generation, or to power an IC engine for water pumping or milling. The remaining sludge forms a good fertilizer. This paper reviews the role of biomass in meeting Kenya's energy needs and how biogas can contribute in alleviating the rural energy crisis. Biogas production and utilization technology was introduced in Kenya in 1954 but by 1986 there were less than 200 installed biogas plants and less than 25% of these were operational. A survey of installed biogas plants (across the country) was carried out (using questionnaires and interviews) to identify the factors that have inhibited the adoption of biogas technology in Kenya; and the problems which have caused the failure of many of the installed plants. The paper gives a detailed discussion of the findings. The survey showed that amoung the reasons for nonadoption are: lack of capital and sufficient input materials (animal dung and water); limited dissemination of technical knowledge and experience to operate biogas plants; and the lack of credit and extension facilities. It was also found that problems such as scum build-up and corrosion, and the lack of sufficient knowledge on the operation and maintenance of the digesters especially on feeding and feedstock dilution (leading to low gas production) has resulted to many failures. The paper attempts to answer some of the problems which have resulted to the many failures and hindered widespread acceptance of biogas technology in Kenya. Finally the issue of dissemination is discussed.

The North-East Region (NER) of India which comprises of eight states, namely Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura shares most of its boundary with China, Bangladesh, Bhutan and Myanmar. The NER accounts for about eight per cent of the country's geographical area and about four per cent of population. Tribals account for more than 30 per cent of the total population of NER. Inadequate and poor infrastructure, inhospitable terrain and a com¬paratively late start in the development process are some of the reasons for economic back¬wardness of the region. However, the NER has certain strengths in different angles to achieve economic development in easy way. From the geo-political angle, the NER is located in a strategic location as it is bounded by these several foreign countries. Naturally it has got both advantages and disadvantages due to its location. So far advantages are concerned it is connected with the South-East Asian countries mainly China, Myanmar, Bhutan, Bangladesh, Malaysia, Thailand, Philippines, Cambodia and Indonesia etc where almost half of the world’s population live. There is no doubt that this vast population could have great advantage for establishing any kind of trade and commerce. But the vary geographical condition basically the rivers and mountains of the country stand as a barrier and create geo–political tensions which ultimately act as most disadvantages factors in creating a conducive atmosphere in the path of developing trade relation among those countries.
