Not AvailableSUSTAINABLE LAND MANAGEMENT DECISIONS AT ALL SCALES REQUIRE SOLID, SCIENCE - BASED INFORMATION. SOIL QUALITY ASSESSMENT CAN PROVIDE THIS REGARDING SOIL PHYSICAL, CHEMICAL AND BIOLOGICAL CHARACTERISTICS AND THE ABILITY TO PROVIDE ECOSYSTEM AND SOCIETAL SERVICES. OUR OBJECTIVE WAS TO MAKE A REGIONAL ASSESSMENT OF SOILS IN THE GARHWAL HIMALAYAS TO DETERMINE THEIR ABILITY TO PERFORM VARIOUS FUNCTIONS AND RESPOND TO EXTERNAL INFLUENCES. FIVE FUNCTIONAL CATEGORIES WERE ASSESSED USING 13 SOIL PARAMETERS FOCUSED ON ECOLOGICAL SUSTAINABILITY . HUMAN LAND USE EFFECTS ON SOILS WERE REFERRED TO NATURAL WOODLANDS AT EACH LANDSCAPE POSITION. WITHIN UPPER SLOPE REGIONS, FLORA AND FAUNA HABITAT, MOISTURE RETENTION , ORGANIC MATTER AND NUTRIENT CYCLING, AIR AND WATER INFILTRATION AND RESISTANCE TOEROSION DECREASED 35,27, 24,AND 9% RESPECTIVELY. AT MID - SLOPE POSITIONS THE ORDER AND MAGNITUDE OF DECREASE WERE ORGANIC MATTER AND NUTRIENT CYCLING, FLORA FAUNA HABITAT AND MOSITURE RETENTION (26,22 AND 16% RESPECTIVELY) . CHANGES WITHIN THE VALLEY WERE LOWEST AVERAGING - 3% FOR FLORA AND FAUNA HABITAT AND 13% FOR ORGANIC MATTER AND NUTRIENT CYCLING. WE CONCLUDE THAT THE MINIMUM DATA SET (MDS) USED PROVIDED A REPRESENTATIVE ASSESSMENT OF SOIL QUALITY AND COULD SERVE AS A BASIS FOR ASSESSMENT IN SIMILAR TROPICAL WATERSHEDS.Not Availabl

Not AvailableTHE NOTE DEALS WITH WORKING OUT OF FUEL WOOD YIELDS FROM HYGIENIC THINNINGS OF 3 YEAR 9 MONTHS OLD EUCALYPTUS HYBRID PLANTATION , RAISED ON BOULDERY RIVERBED IN DOON VALLEY IN JULY, 1982. TO ESTIMATE THE FUEL YIELD FROM DBH , IT WAS PLOTTED AGAINST ACTUAL VOLUME COVERING 1.3 - 10.9 cm DBH RANGE. BASED ON THE DATA QUADRATIC REGRESSION WAS ESTABLISHED FOR THE PREDICTION OF INTERMEDIATE YIELD (VOLUME) FROM THINNING OF FOLLOWS: Y= (-) 0.0005 ( + ) 0.00037 X (=) 0.00019 X2 (R2 = 0.945) WHERE Y = VOLUME (CUM) PER TREE AND X = dbh (cm) . THOUGH NO DIRECT RELATIONSHIP COULD BE ESTABLISHED BETWEEN dbh WEIGHT OF WOOD, THE AVERAGE YIELD/TREE FROM THINNING WAS FOUND TO BE 2.1 KG CORRESPONDING TO 1.4t/ha.Not Availabl

Not AvailableN THE ARTICLE PRESENTS THE RESULTS OF A STUDY UNDERTAKEN BY CSWCRTI , DEHRADUN TO STABILISE AND REHABILITATE AN ABANDONED LIMESTONE MINE AREA LOCATED AT SAHASTRADHARA NEAR DEHRADUN THROUGH A PACKAGE OF VEGETATIVE , MECHANICAL AND STRUCTURAL MEASURES. IT HIGHLIGHTS THE VEGETATIVE MEASURES WHICH INCLUDED PROTECTING THE SITE FROM BIOLOGICAL INTERFERENCE TO INDUCE NATURAL GROWTH AND ALSO REVEGETATING THE AFFECTED AREA WITH SUITABLE GRASS, SHRUB AND TREE SPECIES. THE SUCCESSFUL SPECIES HAVE BEEN NAMED AND DISCUSSED.Not Availabl

BAUHINIA PURPUREA , GREWIA OPTIVA, EUCALYPTUS TERETICORNIS, LEUCAENA LEUCOCEPHALA AND OUGEINIA OOJEINENSIS ARE PRESENTED. THE STUDY INDICATES THAT BULK OF THE ROOTS OF THE FIVE TREE SPECIES ARE FOUND NEAR THE SURFACE, BUT OBSERVATION ON SOIL MOISTURE AND NUTRIENT CONTENT DOES NOT INDICATE VARIATION UNDER THE TREE CANOPIES AND IN OPEN , HENCE THERE MAY NOT BE ROOT COMPETITION IN INITIAL YEARS OF PLANTATION.Not Availabl

IT HAS BEEN OBSERVED THAT ABOUT 8400 cu m OF DEBRIS HAS BEEN RETAINED DURING MONSOON PERIOD OF 1984 BY THE ENGINEERING STRUCTURES. FINER SUSPENDED SEDIMENTS ARE TRAPPED BY GABION THUS REDUCING THE CHANCES OF THEIR GOING TO RIVER. WATER QUALITY PARAMETERS LIKE CALCIUM, MAGNESIUM , SULPHATES AND CHLORIDES ARE REDUCED DUE TO TREATMENT OF ABANDONED MINE AREA, WHICH HELP IN CONTROL OF WATER POLLUTION.Not Availabl

Not AvailableCOMPARATIVE PERFORMANCE OF LEUCAENA LEUCOCEPHALA CULTIVARS VIZ HAWAIIN , SALVADOR, PERUVIAN AND CUNNINGHUM WAS STUDIED AT TWO SITES REPRESENTING DEEP LOAMY SOILS AND RIVERBED BOULDERY SOILS IN DOON VALLEY. THE GROWTH OF ALL THE CULTIVARS WAS HIGHER IN GOOD SOILS THAN IN BOULDERY LANDS. THE DIFFERENCE BETWEEN THE CULTIVARS WERE NOT SIGNIFICANT IN GOOD SOIL BUT IN BOULDERY SOIL 'K-8' CULTIVAR SHOWED SIGNIFICANTLY BETTER GROWTH OVER OTHER CULTIVARS .

Not AvailableTHE AUTHORS BRINGS OUT THAT ENCRAOCHMENT INTO THE FERTILE AGRICULTURAL AND FOREST LANDS THROUGH BANK CUTTING AND DEBRIS DEPOSITION BY MEANDERING AND VIOLENT TORRENTS IS ONE OF THE MAJOR FORMS OF LAND DEGRADATION IN THE FOOTHILLS OF THE HIMALAYAS AND SHIWALIKS . IN DOON VALLEY , ABOUT 1/3 RD OF THE GEOGRAPHICAL AREA IS UNDER THE INFLUENCE OF THE HILL TORRENTS. IN A TORRENT CONTROL RESEARCH PROJECT TAKEN UP AT BAINKHALA TORRENT AT SELAKUI IN WESTERN PART OF THE VALLEY, VARIOUS MECHANICAL AND VEGETATIVE MEASURES WERE TRIED. IN THIS PAPER THEIR RELATIVE EFFICACY AND LIMITATIONS ARE DISCUSSED. CONTROL MEASURES USED IN THE PROJECT WERE REPELLING SPURS, RETAINING WALLS, CROSS BARRIERS AND VEGETATIVE HEDGE ROWS SUPPORTED BY VEGETATIVE SPURS. ALL THESE MEASURES ACHIEVED LIMITED SUCCESS AS NONE OF THEM WAS FOUND TO BE CAPABLE OF HANDLING VIOLENT PEAK FLOW EVENTS. CONSIDERING INITIAL AND MAINTENANCE COST, RISK OF TOTAL FAILURE AND EFFICACY OF DIVERTING THE FLOWS, VEGETATIVE MEASURES AND REPELLING SPURS HAVE BEEN SUGGESTED.Not Availabl
