Using data from villages in three districts of Western Rajasthan, this paper describes the decline in area and deterioration in quality of common property resources over three decades. The decline of common property resources is associated with institutional changes in the villages.

The water resources of a Miocene limestone aquifer in northwest Sri Lanka were investigated. The limestone aquifer receives recharge although it is buried beneath a thick sequence of Quaternary deposits of low permeability which cover the whole basin. Hydrochemical and pumping-test data show that this recharge occurs as leakage through the semi-permeable cover.

The important attributes of macrobenthic community structure viz., species composition and number, population density, biomass, and dominance and diversity indices were measured at different depths and discussed in relation to pollution of Lake Naini Tal. The zone below 7 m depth, where anoxic conditions prevailed for most part of the year, showed complete absence of macrobenthos.

Porpax Lindi. is a small genus found only in the mainland of Asia. It differs from its close relative Eria Lindl. in having the sepals joined into a tube and having a very short pseudobulb which is wider than long. While on an exploration to Silent Valley a curious population of Porpax was located. Comparing with other known species of the genus, the plants were described here as a new species. The plants were growing on lichen covered tree trunks in moist shady places.

Brief studies of microearthquakes in four separate parts of eastern Afghanistan reveal a high level of seismicity over a broad area. In general, the activity is not concentrated on well-defined faults, nor does it define new faults, but seismicity on or close to the Chainart and Sarubi faults attests to their activity. First motions of P waves are consistent with left- and right-lateral strike-slip motion, respectively, on these two faults.

Information available on the present status of genetic diseases in India is relatively meagre, considering the number and varieties of its populations. Data, based mainly on those from uurban referral units, suggest that the incidence is fairly high with the preponderance of certain defects in particular areas and subpopulations.
