最佳实践的简短描述

Soil amendments, plantation along the ridges, slopes, soil moisture conservation and water harvesting were undertaken in the completely degraded and barren patch land (mostly fly ash in place of soil) for the formation of Green Belt. Pit ash treated with surface soil, FYM, Vermicompost, Rice husk, Neem oil cake, DAP, Lime and Micronutrients per plant before plantation of suitable tree species. The project has transformed the area into well established Green belt leading to improvement in soil quality, afforested area and extent of dust pollution has been reduced substantially.|

根据哪些标准和/或指标（与战略无关），在确定建议的实践和相应的技术是否被认为是“最佳”时，应该基于哪些标准和/或指标（与战略无关）？

The methodology adopted for the selection of species, soil amendments was based on soil quality and species most suitable for that kind of soil and climate. The entire methodology including soil testing, soil treatment, and selection of most suitable species for the prevailing climatic and edaphic condition around project site was based on thorough literature survey and reports from previous successful work done on similar sites and its recommendations. The project site was kept under constant monitoring and data related with plantation growth and soil characteristics were recorded. |

最佳实践解决的主要问题

Reclamation of stress site

概述最佳实践解决的具体土地退化问题

The project has been implemented on a highly stressed site and the land quality was totally degraded. Through the project it was expected to meet with the problem of degraded soil quality soil erosion, soil moisture conservation and further amendments in the soil quality.  The project area would also convert in to green belt, which was totally unproductive, before the project was taken up.|

本技术的简要说明和技术规范

With the aim of green belt development around Chandrapura Thermal Power Station, Chandrapura, Dhanbad soil amendments, plantation along the ridges, slopes, soil moisture conservation and water harvesting were undertaken in the completely degraded and barren patch land (mostly fly ash in place of soil) for the formation of Green Belt. A hi-tech nursery equipped with all the modern facilities including mist chambers, green house and root trainers was  established for raising quality seedlings of Acacia mangium, A. auriculiformis, Albizzia lebbek, Alstonia scholaris, Azadirachta indica, Bombax ceiba, Bouhinia variegate, Delonix regia, Dalbergia sisoo, Eucalyptus tereticornis, Gmelina arborea, Melia azadiracht, Sesbania grandiflora, Pongamia pinnata, Syzygium cumini, Terminalia arjuna, Swietenia mahogani, Spathodia campanulata, Peltopherum ferrugineum, Cashew nut etc. Two types of afforestation approach were followed. The first was afforestation on ridges and slopes of Ash pond areas with pit ash treated with surface soil, FYM, Vermicompost, Rice husk, Neem oil cake, DAP, Lime and Micronutrients per plant before plantation of suitable tree species (28500 in number). The second was afforestation on degraded forest lands (20 ha). 15000 seedlings were planted after pit soil treatments of good surface earth, Vermicompost, Rice husk, Neem oil cake, DAP, Lime and Micronutrients per plant before plantation. The project has transformed the area into well established Green belt leading to improvement in soil quality, afforested area and extent of dust pollution has been reduced substantially. The transformation of the degraded land has been reflected in excellent growth of tree species and remarkable regeneration of herb and shrub flora; a sign for establishment of successional process.|

描述现场影响（按类别划分的两类主要影响）

The project has been implemented on unproductive, fly ash site. The site was completely degraded and it was completely barren patch. |
The project has transformed the area into well established Green belt leading to improvement in soil quality, afforested area and extent of dust pollution has been reduced substantially. The invading species of grasses n herbs has also been increased.|

描述两个主要的场外影响（即不是发生在现场，而是发生在周围区域）

The project led to spread general awareness among people living in and around the area towards importance of afforestation for improvement of environment.

对生物多样性和气候变化的影响

解释原因:

The factors related to climate change has not been assessed but with respect to biodiversity aspect, the situation has been improved as grass, herbs, shrubs and even tree species have started regenerating in the reclaimed site. Due to this development the faunal population including birds has been seen in large number in the site.|
