Protection and preservation of the marine environment is a topical issue around the Baltic Sea. Not least does it refer to vessel-source pollution. The Baltic Sea is a particularly vulnerable sea area with its narrow waters, often severe climatic conditions, and growing tanker traffic, especially to and from Russian ports at the far end of the Gulf of Finland. By way of example, oil transports in the Gulf of Finland tripled in 1995 to 2003, recently reaching to some 78 million tons a year.

This article records the preliminary results of an investigation of some of the causes of the variations in the yield and composition of milk. The influence of the season of the year, and the influence of climatic conditions on the average yield and composition of the milk of a herd, are discussed.The relationships between the data are studied by means of simple corre-lation and also by means of partial correlation. The temperatures used are the average temperatures for the periods between the milkings. Thus the day-temperature is the average temperature of the interval between the morning and evening milking, and the night temperature is the average temperature of the interval between the evening milking and the next morning milking. The daily temperature is the average of these two temperatures.

Kodagu is the smallest district of Karnataka. It is considered as the Switzerland of the East and Kashmir of India. The district is basically an Agro-based economy. It is the second largest producer of coffee of the country and now added with eco-tourism because of its scenic beauty. Kodagu doesnot have any large scale industries but only agro based and MSME sector. It is because of its topography and climatic conditions. One such micro sector was the “Grinding stone production of the Paloor Village of Madikeri Taluka of the district. The grinding stones of this village was very famous not only in the district but also in the nearby districts like Mangaluru, Mysuru and also Bengaluru. The production was gradually decreasing and since two years it has come to a standstill due to lack of demand. Not only the stone grinders but also some of other rural enterprises are in the verge of fading away. This paper makes an attempt to focus on the realities and to find some remedies to the problem. KEY WORDS: Rural Enterprise, MSME, Stone Grinders

Red- and purple-leafed seedlings and clonal material selected for superior color and growth under northern climatic conditions may exhibit progressive color loss and reduced growth rates when exposed to the hot summers and high night temperatures of more southern climates. Studies were conducted to characterize the color loss associated with red-leafed seedlings of Acer palmatum Thunb. (Japanese maple), and to determine to what extent night temperatures affect the dark respiration, growth, and anthocyanin expression of A. palmatum `Bloodgood'. The percentage of seedlings within each of five color classes was determined for five dates from spring to early fall. Significant shifts in class distribution occurred on every evaluation date tested. The class changes contributing the most to these shifts varied with age of leaf material and date. Dark respiration rates increased by 0.09 mg CO2/g leaf dry weight per hour for every 1C rise in temperature, regardless of exposure duration. Dark respiration rates of 0.69 and 1.73 mg CO2/g per hour were found at 14 and 26C, respectively. The greatest amount of growth occurred during weeks 6 through 8 at a night temperature of 14C. Plant growth during this period increased by an average 51%, compared to that at warmer night temperatures. Ultimately, total plant growth at 14C decreased 7%, 19%, and 32% as night temperatures increased from 18 to 22 to 26C. Leaf redness index values at 14 or 18C were from two to seven times greater than those at warmer night temperatures.

The tribal communities live in about 15% of the country’s areas in various ecological and geo-climatic conditions ranging from plains and forests to hills and inaccessible areas. The tribal groups are at different stages of socio-economic and educational development. While some tribal communities have adopted a mainstream way of life, at the other end of the spectrum, there are 75 groups still not adopted mainstream life, Particularly Vulnerable Tribal Groups (PTGs), who were identified earlier for having the following characteristics:(a) pre-agriculture level of technology;(b) stagnant or declining population;(c) extremely low literacy and(d) subsistence level of economy

1. The problems involved in conservation of fodder in Northern Rhodesia are discussed in relation to climate and present day practices. Special reference is made to the conservation of grassland herbage.Climatic conditions do not appear suitable for haymaking.2. A number of silage samples were collected from dairy farms in the territory and from Mount Makulu Research Station. Chemical analyses of these samples are given and their nutritional value is discussed with special reference to their crude protein contents. The majority of the silages were found to have low crude protein.3. A type of miniature tower silo designed for experimental work is described.4. Three crops commonly used for ensilage, i.e. maize, maize with legume and Napier grass, were compared with giant Rhodes grass (Chloris gayana Kunth.) when ensiled in these miniature silos. The type of fermentation and loss of nutrients was studied. Rhodes grass ensiled at the early flowering stage was found to compare favourably with the other three. Napier grass (Pennisetum purpurem) cut when over 6 ft. high did not ensile well and had a low crude-protein content.5. Giant Rhodes grass was ensiled in miniature experimental silos at two different stages of growth. Cutting the grass at a height of 20 in., three times during the season, resulted in a higher yield of dry matter and crude protein per acre than cutting once at a height of 40 in. even when the resultant aftermath growth was included.
