| Abstract: | The present study on the dynamics of land use in recently settled forest areas. In the course of events, tribals lost their land; the demographic structure of Attappady changed; the cropping pattern got diversified; traditional techniques of production were ruined; new crops and new techniques of cultivation came to stay; and the entire cost and return structure of production underwent radical change. Migration to Attappady is essentially a continuation of the Malabar migration process from Travancore, through, some people from Tamil Nadu also had migrated to this region earlier. The demographic structure, along with land structure, has changed in favour of the settlers within a short span of time. Lack of security of ownership has acted as a strong reason for wanton exploitation of land resources. The major influencing factors on crop choices among settlers were labour endowment, date of settlement and education. Attappady is an unique ecosystem in Kerala characterized by many interdependables. The latest hand of environmental degradation is a grave danger especially on sloppy terrains,which are under cultivation of tapioca and dry annual crops like groundnuts, cotton, grams etc. Soil erosion as a result of the unplanned cultivation of these crops has resulted in dramatic decline in soil fertility and hence low crop productivity. This calls for a watershed management approach for the sustainable development of the region. A progressive agrarian transformation is warranted to maintain the homegarden as a sustainable production system in ecological and socio-economic terms. |

| Abstract: | The primary aim of this work has been to develop a cost effective process that can be operated at room temperature for developing latex reclaim with superior mechanical properties. With this objective in mind the researcher proposes to study the reclaiming action of four different chemicals on latex products waste. Waste latex products are chosen because it has a higher potential to generate good quality rubber hydrocarbon since all latex products are based on either high quality concentrated latex or creamed latex. Moreover, all latex products are only lightly crosslinked and not masticated and hence not mechanically degraded. The author also proposes to fully explore the possible application of latex reclaim in various fields.. |
