Soil erosion is viewed as a major process of land degradation in rubber-growing areas under hot moist sub-humid to humid agro-ecological region of Kerala and Karnataka in India. The bench mark survey with geo-reference at 121 locations was carried out with the objective of deriving soil-water conservation strategies in the extensive rubber-growing areas of Kerala and Karnataka (5.2 lakh hectares with productivity of 1514 kg/hectare). In the present study, Rainfall erosivity for 7 locations (considering
monthly rainfall 1971 to 2007) and soil erodibility (Epipedons of 121 bench mark soils) were used.
Monthly rainfall data, for the period 1971 to 2007 were used to compute the Modified Fournier index
(MFI) The results showed that June, July and August receive maximum rainfall with very high Modified
Fournier index (>160) from 433.4 (Trivandrum) to 2641.2 MJ mm ha−1 h−1 y−1 (Kannur) with an increasing from southward to northward. The soil erodibility (K) for five major soil subgroups of humults were 0.15 to 0.24 indicating that these soils are weakly susceptible to water erosion. Majority of the area (45.73% of TGA) is susceptible to extremely strong erosion followed by very strong erosion on 25.40 per cent of TGA and strong erosion in 22.28 per cent of TGA. The soil loss estimations can serve as effective inputs in prioritizing soil conservation strategies and management in rubber growing areas of Kerala and Karnataka.

The present study was undertaken with aim to understand the perceptions of indigenous communities about climate change pattern and its local impacts on climate variables, seasons, agriculture, biodiversity and adaptive strategies in geographical and technological-isolated Pangi valley situated in Chamba district, Himachal Pradesh. Randomly selected 120 respondents were interviewed and their perceptions were recorded on pre-designed questionnaire. The climate change impacts are experienced in the form of decreased snowfall (98.3%), temperature rise (97.5%), late onset of monsoon (90.8%), decreased rainfall (76.7%), reduced snow-melted water availability (86.7%) and increased drought incidences (85.8%) of over the years. Further, these climatic changes affecting agriculture through early shifts in crop season (80.8%), shorter growing season (91.7%), introduction of fruit and vegetable crops (90.8%), increased incidence of insect-pest (81.2%) and diseases (84.2%) and thereby decline in crop yield (70%). However, majority of the respondents undertaken adaptive strategies such as crop diversification, traditional mixed-cropping, mixed farming, crop rotation and agro-forestry/agro-horticulture systems to cope with climate change but they are either little or unaware of modern farming practices such as snow water/glacier runoff harvesting, agro advisory services, mulching and zero tillage as adaptation strategies.

Land suitability for irrigation in semi-arid regions is important for agricultural development and to overcome water scarcity. The detailed soil survey of Garakahalli micro- watershed (447 ha) of Karnataka was carried out and mapped into 85 mapping units. The soil units were evaluated for surface irrigation. The suitability maps showed 74.06 per cent arable land, out of which 69.19 per cent of land is suitable for surface irrigation and remaining is unsuitable due to the limitation of the topography and stoniness. The detailed land resource data base in association with GIS and remote sensing was highly efficient in modeling and developing land suitability maps which can be used as a planning tool to optimize the agriculture in semi-arid regions of Karnataka.

The length of growing period (LGP) of four micro-Iandfonns in Bankura district, West Bengal, was determined after estimating the per cent moisture content as well as the stored moisture of soils. Soil samples of profiles located at each landform, represented by a transect, were collected at regular incremental depth in the second week of November. Per cent moisture and stored moisture of soils were found to vary with landforms. Soil moisture (per cent) of landforms increased in the order: Tanr (ridge land) > Baid (back slope) > Kanali (toe slope) > Bahal (valley fill). It was observed that the actual moisture storage for soils < 1 m depth was less than the respective AWC values. However, for soils >1 m depth, the values remain unchanged. The duration of growing period was 150-160 days (Tanr), 160-170 days (Baid) as compared to Kanali (180-190 days) and Bahal (200-210 days). Keeping this in view, a rainfed cropping system compatible with the moisture availability period (LGP) of each landform was suggested. Baid landform was judged as the ideal area for growing alternative field crops such as redgram, cowpea, blackgram, sesame, sunflower, etc. instead of existing rainfed rice based on corrected LGP measurements
