The Spot-billed Pelican (Pelecanus philippensis), a near threatened bird and one of eight pelican species in the world, can be found only in South and Southeast Asia over an area between 129000 and 181000 km2 with strongholds in India, Sri Lanka, southern Cambodia and coastal areas of Sumatra. In India,it is presently distributed in southern and northeastern India with concentrations in Andhra Pradesh, Tamil Nadu, Karnataka and Assam states. The present study deals how the spot- billed pelicans utilize the wetlands as well as their behaviour is noted in order to plan conservation and management strategies for the species.

Leafhopper genera and species of the tribe Mukariini from the Indian subcontinent are revised. Nine genera and 22 species including two new genera, one new subgenus and 12 new species are dealt with. The new taxa described are Aalinga gen. nov. with its type species Aalinga brunoflava sp. nov. (India: Andaman Islands), Buloria indica sp. nov. (India: Karnataka). Buloria zeylanica sp. nov. (Sri Lanka), Flatfronta bella sp. nov. (India: Karnataka; Bangladesh), Mohunia bifurcata sp. nov. (Myanmar), Mukaria omani sp. nov. (India: Gujarat, Karnataka, Madhya Pradesh), Mukaria vakra sp. nov. (India: Karnataka), Mukariella gen. nov. with its type species Mukariella daii sp. nov. (India: Manipur), Myittana (Benglebra) cornuta sp. nov. (India: Karnataka), Myittana (Myittana) distincta sp. nov. (India: Karnataka), Myittana (Savasa) subgen. nov. with its type species Myittana (Savasa) constricta sp. nov. (India: Andhra Pradesh, Gujarat, Haryana, Himachal Pradesh, Karnataka, Madhya Pradesh, Punjab, Tamil Nadu, Uttarakhand) and Scaphotettix arcuatus sp. nov. (India: West Bengal, Meghalaya, Mizoram). Genera Buloria Distant (new placement), Crispina Distant (new placement) and Myittana Distant (new placement) are placed in the tribe Mukariini. Genus Mohunia is redefined based on the study of its type species. Benglebra Mahmood & Ahmed 1969 is synonymised with Myittana Distant 1908 and considered as its subgenus. Myittana (Benglebra) alami (Mahmood & Ahmed) comb. nov., Myittana (Savasa) bipunctata (Mahmood & Ahmed) comb. nov.. Myittana (Benglebra) introspina (Chen & Yang 2007) comb. nov. and Mukariella bambusana (Li & Chen) comb. nov. are proposed; the first two species were earlier placed in the genus Benglebra, the third species in the genus Mohunia and the fourth in the genus Mukaria. Genera Flatfronta Chen & Li and Myittana are new records for India and Scaphotettix striata Dai & Zhang is a new record for the Indian subcontinent and Sri Lanka. All taxa dealt with are described and illustrated and keys for genera and their species are also given.

Indobanalia thyrsiflora is an endemic species occurring in peninsular India (Andhra Pradesh, Karnataka, Kerala and Tamil Nadu States) and Sri Lanka. A nomenclatural study of the basionym Banalia thyrsiflora, published by Moquin-Tandon in Candolle’s Prodromus (year 1849), is carried out and the name is lectotypified on a specimen deposited at P (barcode P00609924); isolectotypes are traced at K and CAL. A preliminary morphological characterization of the species is also given, based on field surveys and examination of herbarium specimens. We noted that I. thyrsiflora is highly variable. However, we prefer to avoid, for the moment, taxonomic conclusions about the various morphotypes found, waiting the complete results of this ongoing morphological and molecular investigations.

Groundnut, the most important edible oilseed crop in India and is the low priced commodity with valuable source of all the nutrients. It is the sixth most important oilseed crop in the world. It contains 48-50% of oil and 26-28% of protein, and is a rich source of dietary fiber, minerals, and vitamins. More than seventy percent of the area and production is found in Gujarat, Andhra Pradesh, Tamil Nadu and Karnataka. Anantapur district is the largest groundnut producing district The present study was carried out with the objective of exploring movement of produce along the value chain, the Value addition, Price spread and Profit margins incurred and found that there is a wide range of price gap observed from producer of oilseed to the final consumer of edible oil due to the number of stakeholders involved in the value chain.

This is a remarkable volume. Not so much for what it says as much as for what it never gets around to saying. The introduction states that this is the "first major research study to be published under the rural component" of the World Employment Programme. The volume consists of studies of various aspects of rural income distribution in: Pakistan (S.M. Naseem); Indian Punjab (Indira Rajaraman); Uttar Pradesh (Rohini Nayyor); Bihar (Rohini Nayyor); Tamil Nadu (C.T. Kurien); Bangla¬desh (A.R. Khan); Sri Lanka (E.L.H. Lee); West Malaysia (E.L.H. Lee); Java (Ingrid Palmer); Philippines (A.R. Khan); and China (A.R. Khan). There is also an anonymous introduction which attempts a synthesis and summary.

Soil erosion and soil loss is one of the common problems threatening the environment. This degrading phenomenon declines the soil fertility and significantly affects the agricultural activity. As a consequence, the productivity of soil is affected unquestionably. In this reason, there is a basic need to take up conservation and management measures which can be applied to check further soil erosion. Even though, soil erosion is a mass process spread cross the watershed, it is not economically viable to implement conservation techniques to the entire watershed. However, a method is a pre-requisite to identify the most vulnerable areas and quantify the soil erosion. In this study, Revised Universal Soil Loss Equation (RUSLE) has been accepted to estimate soil erosion in the Kummattipatti Nadi watershed part of the Coimbatore district of Tamil Nadu, India. This model has several parameters including runoff-rainfall erosivity factor (R), soil erodability Factor (K), topographic factor (LS), cropping management factor (C), and support practice factor (P). All these layers are prepared through geographical information system (GIS) by using various data sources and data preparation methods. The results of the study shows that the annual average soil loss within the watershed is about 6 t/ha/yr (metric ton per hectare per year). Higher soil erosion is observed in the land use classes of gullied wasteland, open scrub forest and degraded plantation. The soil erosion risk is extremely higher on the steep slopes and adjoining foothills. The proper conservation and management strategies has to be implement in this watershed for the development.
