In the lateritic tract of South-West Bengal Sal coppice forests, JFM programme had started in late 1990s and is apparently successful. But the major factor for the continuity of the programme depends on the viability and buoyancy of the institutions i.e. Forest Protection Committees (FPCs) formed for this purpose. In this study attempts were made to assess the income of the FPC members from different sources and resources in Midnapore District of West Bengal, selecting sample FPCs all over the district. How far such income is encouraging to keep them involved in the programme and the ways and means to enhance income have also been indicated and suggested.

JFM is a recent concept adopted by various States of India, which is an institution building process (not a silvicultural management system) by which it is easier to manage the forests through active participation of the fringe people. But the viability and continuity of these institutions rest on certain factors. The most important is the sustainability of the development process by which the benefits received by the FPC members should be commensurate, at least to some extent, with the services rendered by them in managing the forests effectively. Attempts are made in this article to examine this from institutional, economic and ecological point of view of this programme and suggest improvements. Income of the beneficiaries may not be complementary, but definitely it can be supplemented to great extent, if certain technical and technological measures can be taken. Above everything, motivation and interaction with the FPCs are vital and imparting training for value addition of natural resources is an important factor to augment the income.- An Introspect into Management Aspects of the Institutions - Case Study of the Selected FPCs in the Forest Divisions of Midnapore District, West Bengal

In West Bengal canes occur naturally within the agro-climatic zones of Sub-Himalayan Bhabar and Tarai. With the exception of two high altitude canes, other eight species appear in wet mixed plain forests in the swampy pockets. In the recent past, canes were extracted on a cutting cycle of 3 to 5 years. But over-exploitation surreptitiously, extraction of immature plants and clearfelling of natural forests depleted these valuable resources, which were much in demand in local rattan industries. At present, discontinuing clearfelling in natural forests under the provision of Forest Conservation Act, ban on extraction of cane in Working Plan prescription and resorting to artificial regeneration in suitable habitat help rehabilitation of cane in this State.- The Strengths and Weaknesses of the Joint forest Management in West Bengal

In West Bengal the site and situation are different in different parts of the State. The South-West lateritic tract was in severe degradiation. Therefore, priority was given to this area first to form the protection committee, under Joint Forest Management programme and gradually extended to other areas. The strength and weakness of the programme and their remedial measures are suggested.- Geology of Great Nicobar Island

The Joint Scientific Expedition to the Great Nicobar Island provided opportunity for obtaining a comprehensive knowledge of the major geological features of the island. The various rock formations were examined and their stratigraphic sequence was established. Major structural features were noted and the geological history of the island is reviewed. This reveals a close similarity with the geology of Andaman Islands. Other aspects studied are economic geology, nature of soils and water resources.- Photochemical Behaviour of [Co(NH3)5HC2O4]2+ in Microheterogeneous Media

In the present work a comparative study of the photochemical behaviour (steady-state photolysis) of oxalatopentaamminecobalt (III) perchlorate, [Co(NH3)5HC2O4](ClO4)2, in pure aqueous as well as in premicellar and micellar solutions of three different (anionic, cationic and non-ionic) surfactants has been undertaken. The photochemical reactivity of the complex has been found to charge in the following respects. (1) The photoaquation of ammonia does not take place in micellar solutions of all the three surfactants used. (2) The quantum yield of Co2+(ΦCo2+) changes as the concentration of surfactant changes with a concomitant change in the structure of the solution. The manner in which ΦCo2+ varies depends on the nature of the surfactant. The CMC of a surfactant can be determined from the plot of ΦCo2+ vs. -log [Surfactant]. (3) The effect of [CH3COO-] variation on ΦCo2+ is more prominent in micellar solutions.- Comparative Evaluation of Reference Evapotranspiration Estimation Models In New Bhupania Minor Command, Jhajjar, Haryana, India

Accurate quantification of reference crop evapotran-spiration (ETo) plays a significant role in determining crop water requirements in irrigated agriculture. A plethora of methods for the estimation of ETo are available. However, the regional suitability of these methods needs to be assessed given the limited availa-bility of meteorological data. In this study, daily estimates of 11 ETo models were selected and compared with the FAO-Penman–Monteith equation (FAO-PM). The select-ed methods were Blaney–Criddle (BC), Jaisen–Haise (JH), Hargreaves method (HM), McGuinness–Borndne (MB), Chapman (CM), Abtew model (AM), Turc method (TM), FAO-PM equation, Penman equation (PM), Prie-stley–Taylor (PT) and Matt–Shuttleworth (MS). Evalua-tion of these models was carried out during 2016–20 in the New Bhupania Minor Command of the Dulhera dis-tributary, Western Yamuna Canal Command (WYCC), Haryana, India. The selected models were evaluated to find a substitute for the FAO-PM equation based on different statistical indices. It was observed that the PT method performed best and was in line with the FAO-PM equation with correlation coefficient, root mean square error, mean absolute error, Nash–Sutcliffe co-efficient and mean bias error as 0.92, 0.74, 0.48, 0.83, 0.171 respectively. Based on this study and statistical error indices values, the models can be ranked as PT > CM > TM > JH > AM > PM > MS > HM > BC > MB. Thus, we recommend using the PT model for the esti-mation of ETo in the study area with available meteoro-logical parameters for irrigation scheduling.Keywords
