A research study was conducted in the state of Arunachal Pradesh in order to identify the various problems faced by the rice (Oryza sativa L.) and maize (Zea mays L.) grower in the state due to climate change and the various mitigation and adaptation measures undertaken by them in view of the problems faced by them. The study was carried out for the time period from 1987 to 2018 in two districts viz. East Siang and Lohit of Arunachal Pradesh; being the highest producing district of rice and maize in the state respectively. The study showed that the respondents perceived climate change and reported to have observed a change in the timing and duration of rainfall received along with changes in temperature. They reported various problems faced by them in the duration of the study while ranking decreasing yield as the most important problem faced by them, followed by pest and disease infestation and weed infestation in the fields. The farmers also adopted various means in order to counter the problems faced due to climate change like changing the cropping time and pattern, introducing climate resilient varieties and switching to more economically profitable crops. In view of the observations made during the study, some policies and future course of actions suggested for the problems faced by the farmers can include adoption of sustainable and diversified form of agriculture, involvement of Government, cooperative and self help groups to reduce price risk. Farmers can adopt water saving technologies like controlled irrigation, development of crop monitoring, climate forecasting and mapping the climate susceptible areas are the immediate need of the hour.

A New Species

A new species of nemachilid loach Aborichthys barapensis, is described based on two adult specimens (91 and 97 mm SL) from the Barap Stream (a tributary of the Brahmaputra River basin) in the southeastern most part of the state of Arunachal Pradesh bordering Myanmar. The new species is distinguished from its congeners in having a narrow black basicaudal bar without a black ocellus on the upper end (vs. present); and in having a very low dorsal and ventral adipose crests (vs. prominent; absent in A. waikhomi). The new species is further distinguished from its congeners by the following combination of characters: body with 24–26 oblique bars along the flank; interspace narrower than bars on body; moderately rounded caudal fin with five distinct black to brown cross bars; vent closer to the caudal-fin base (44.1–45.1 % standard length) than to snout tip.

A three year study (from December 2011 to December 2014 and in June 2015) on butterflies covering four major forest sub-types as classified by H.G. Champion & S.K. Seth in 1968 in ‘Forest Types of India’, which occupy 60% of the forest area lying below 2,500m across Arunachal Pradesh State in the eastern Himalaya of India, revealed 415 taxa belonging to six families (Hesperiidae: 74 species of 42 genera; Papilionidae: 37 species of 10 genera; Pieridae: 36 species of 15 genera; Lycaenidae: 85 species of 49 genera; Riodinidae: 7 species of 3 genera & Nymphalidae: 176 species of 71 genera, respectively).  These included many endemic and rare species typical of these forest sub-types, i.e., (i) 2B/1S1 Sub-Himalayan Light Alluvial Semi-Evergreen Forest (32 species), (ii) 2B/ C1(a) Assam Alluvial Plains Semi-Evergreen Forests (5 species), (iii) 2B/2S2 Eastern Alluvial Secondary Semi-Evergreen Forests- (15 species) and (iv) 3/1S2 (b) Terminalia-Duabanga (3 species), respectively.  The relative number of species and individuals sampled were the highest at altitudes below 500m, and gradually declined as the altitude increased to 2,000m, and above 2,500m species richness declined sharply.  The number of species and their relative abundance were the highest during July–August (Monsoon-first peak) and then again in November-December (Autumn-second peak), while the numbers were lowest during winter.  These findings suggest that these four forest types are important both for the purpose of ecotourism as well as conservation of endemic and rare taxa found in the eastern Himalaya and northeastern India at altitudes below 2,000m.  A complete list of all the taxa sampled is given along with relative abundance status during sampling, Indian Wildlife (Protection) Act, 1972 status, and distribution in different forest types in the state.  Ten potential butterfly ecotourism zones are suggested for the state.  Planning land-use for biodiversity conservation based on butterfly-forest type associations, by taking forest sub-types as units of conservation, is suggested as an option for the eastern Himalaya.

The genus Usnea Dill.ex Adans. is worked out based on the new collections and represented by 29 species in the state of Arunachal Pradesh, a biodiversity hotspot in north-east India. Six species viz. Usnea angulata Ach., U. compressa Taylor, U. himalayana Bab. U. montisfuji Motyka, U. perplexans Stirt., U. picta (J. Steiner) Motyka are new additions to the state lichen biota. Two species namely U. cineraria Motyka and U. thomsonii Stirt. are endemic to the Himalayan region. The genus is a potent source of phytomedicine and has multifarious ethnobotanical, phytochemical and pharmacological significance. An identification key to all the species is provided to facilitate their identification while new additions to the state are dealt briefly along with their photographs and a table showing the distribution of species within the state. Indian species of Usnea need thorough phytochemical screening to record their unique uses for the human benefits.

Northeastern India, situated within the Indo-Burma and eastern Himalaya biodiversity hotspot complex, is known for its high diversity of wild felid species.  For most of these species, however, data on distribution and population trends are limited.  Here, we present photographic records of the Marbled Cat Pardofelis marmorata and Asiatic Golden Cat Catopuma temminckii from outside protected areas in the state of Nagaland.  These records are from community forests around the Dzükou Valley in Nagaland and are some of the few records of the species from the state.  The confirmed presence of the two species highlights the pivotal role of community-managed forests in the conservation of endangered species in the region.

Disaster Capitalism

As today’s catastrophic Covid-19 pandemic exacerbates ongoing crises, including systemic racism, rising ethno-nationalism, and fossil-fuelled climate change, the neoliberal world that we inhabit is becoming increasingly hostile, particularly for the most vulnerable. Even in the United States, as armed white-supremacist, pro-Trump forces face off against protesters seeking justice for African Americans, the hostility is increasingly palpable, and often frightening. Yet as millions of Black Lives Matter protesters demonstrated after the brutal police killing of George Floyd, the current, intersecting crises – worsened by Trump’s criminalization of anti-racism protesters and his dismissal of science – demand a serious, engaged, response from activists as well as artists. The title of this article is meant to evoke not only the state of the unusually cruel moment through which we are living, but also the very different approaches to performance of both Brecht and Artaud, whose ideas, along with those of others – including Benjamin, Butler, Latour, Mbembe, and Césaire – inform the radical, open-ended, post-pandemic theatre practice proposed in this essay. A critically acclaimed dramatist as well as Professor of English and Playwriting at California State University, Northridge, Mitchell’s published volumes of plays include Disaster Capitalism; or Money Can’t Buy You Love: Three Plays; Brecht in L.A.; and Ventriloquist: Two Plays and Ventriloquial Miscellany. He is the editor of Experimental O’Neill, and is currently at work on a series of post-pandemic plays.
