Rice cultivation in North East India is organic by tradition; however, the recent outbreaks of the rice-swarming caterpillar, Spodoptera mauritia Boisduval, have compelled rice-farmers to use synthetic insecticides. The outbreak in 2016 affected more than 56,768 ha of winter rice in 28 districts of Assam. About 25,545–42,576 L insecticide was applied in the state to combat the outbreak. This is one of the highest insecticide loads ever to be added to the rice ecosystem of Assam. Such a load, if added repeatedly with the reoccurrence of outbreaks, may affect the innate resilience of the rice ecosystem in the long run. In this paper, the outbreak of RSC has been analysed from an ecological perspective in order to replace the existing policy of exclusive dependence on insecticide. The review will help the researchers, extension workers and policy makers of the rice producing countries, more specifically in Asian countries, which together account for more than 91% of the world’s rice production.

The Act East Policy of India which actually succeeded India’s Look East Policy has deepened India’s engagement and ties with the East and Southeast Asian countries. The Act East Policy is a continuation of former Look East Policy of India which was introduced by P. V. Narasimha Rao Government in the early years of 1990s. If we, however, look at both the policies we could find the Act East Policy has reached far beyond in several areas where the former policy could not reach. The Act East Policy emphasizes on practicing more action oriented policies towards East and Southeast Asian Countries so that India can emerge as a major power in Asia. Under the Act East Policy, India’s linkages and connectivity with the Southeast Asian countries and ASEAN have been strengthened through a numbers of bilateral and regional trade agreements. The new Policy also aims at effective implementation of proposed policies and programs by developing better relations with these countries through bilateral talks, trade, business and economic, strategic and cultural ties. This paper tries to summarize the opportunities that the Act East Policy offers to India in general and to the North-East India, in particular. To point out the role Silchar and its strategic importance in the Act Policy is another objective of this paper. At the end, it highlights the major challenges which may harm the growth of Act East Policy of India.

This paper analyses the resource-productivity, technical efficiency (TE) and allocative efficiency of rain fed farmers in Nigeria. The results of the parameters that enter the production function shows that herbicide has the highest elasticities, then seeds, followed by fertilizer and land while labour has the least contribution to output. Also, the result for the allocative efficiency based on the computed <i>MVP<sub>x</sub></i> = <i>P<sub>x</sub></i> show that none of the respondents optimally allocated the inputs. However, a greater number of the respondents were found to underutilized variables like land, seeds, fertilizer and herbicide (<i>MVP<sub>x</sub></i> < <i>P<sub>x</sub></i>) while a greater number of the farmers over utilized labour (<i>MVP<sub>x</sub></i> > <i>P<sub>x</sub></i>). But in both cases, it was revealed that the use of more labour decreased the rice production from the study faster than any of the selected variables. The mean TE index was found to be 0.75. This suggests that 0.25 of rice yield is forgone due to inefficiency. The significant gamma (γ) value of 0.873 establishes the fact that a high level of technical inefficiency exists among the sampled farmers. Extension contact and access to credit are found to be significant determinants of TE among the farmers. Hence, agricultural policy makers in Nigeria should focus on how farmers could follow appropriate farm practices in the course of technology adoption to prevent under utilization of farm inputs via the intensification of extension activities in the country and accessibility to credit by farmers should be given more priority. Pursuing these will raise the productivity and efficiency of rice production in the country in the long run.

The North-East India (NEI) consists of eight states and it is a ‘mixed bag’ of several ethnic groups. The region is known for its unexploited natural and human resources which are the basic factors of economic development. So, the energetic entrepreneurs are necessary if we want to harness it properly. With the emergence of Globalization and more recently with the inception of ‘Look East Policy’, trade and commerce has become an important tool in linking this region with the Asian and South East Asian countries. Look-East Policy is expected to provide an opportunity to overcome the problem of distance from big markets. It is apparent that NE India as a whole needs a big push or a kick starts to launch the economy on the development path through trade and commerce. But, it is greatly handicapped by law and order situation or bandh and blockade in the region. Economic development of a region is quite illusive agenda without developing trade and commerce in the region. Peaceful environment in the region is the pre-requisite condition for economic development. Keeping this in mind, the question that arises is who will be the active agents in bringing peace in the region?

Rice is one of the most important food crops of India in terms of area, production and consumer preference. India is the second largest producer and consumer of rice in the world. Trends in global rice consumption largely follow those in global production, rising steadily over the last few decades. However population growth has outpaced growth in rice production, such that per capita production, and thus per capita consumption is declining. For future planning, it is therefore necessary to evaluate the growth pattern of rice production. An attempt has been taken in this paper to forecast (through Box-Jenkins technique) the production of rice in North-East states of India. The study finds that the respective models for best forecasting of Rice production are ARIMA (1,1,0) for Assam, ARIMA (1,0,1) for Arunachal Pradesh, ARIMA (1,1,2) for Nagaland, and ARIMA(1,0,0) for Sikkim. This study also finds that Forecasting for Mizoram is not possible under the present methodology since the data series is non-stationary and they are not becoming stationary even after second difference. Similarly forecasting of rice production of Tripura and Meghalaya is also not viable. The data series are I(1), but in the first differenced series there is no significant spike in ACFs, indicating that the first differenced series are white noise. Moreover forecasting indicates possibility of a decline in rice production in most of the states in North East India.


Subject Turbulence in India-Bangladesh relations. Significance Indian Prime Minister Narendra Modi earlier this week cancelled a scheduled visit to Bangladesh, due to concerns over the spread of COVID-19. India-Bangladesh relations have grown stronger since Modi came to power in 2014. In recent weeks, though, Dhaka has expressed concerns over India’s Citizenship (Amendment) Act (CAA), which fast-tracks claims to Indian citizenship by non-Muslim migrants from three majority-Muslim South Asian countries including Bangladesh. Impacts By investing in infrastructure development in the north-east, India will strengthen connectivity with South-east Asia as well as Bangladesh. India will step up cooperation with the United States and EU to execute development projects in Bangladesh. Delhi-Dhaka relations will be a key issue in Bangladesh’s next general election, likely to take place in 2023.

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.
