| dc.description | In the present investigation entitled “Appraisal of carbon sequestration potential of Hardwickia binata Roxb. based Silvopastoral system” was studied at silvopastoral agroforestry system present at research farm of Directorate of Agro-ecology and Environment Centre and in block plantation of Hardwickia binata present at Dairy farm,Department of Animal husbandry and Veterinary science, Dr. PDKV, Akola to evaluate the biomass production and carbon sequestration potential of Hardwickia binata based Silvopastoral agroforestry system of 30-year age and sole plantation of Hardwickia binata of 28-year age trees. Moreover, such information helps to attain more clarity on the functional role of tropical agroforestry system with respect to diverse economic, social and ecological functions that may ultimately help to reduce atmospheric CO2 stock. Biomass production in any system reflects the potential production of their vegetation components (woody perennial trees, shrubs and crop/herb species) in a set of environment, number and types of constituent species, age and their management. The carbon storage in aboveground vegetation categories depends upon their management practices and prevailing ecological variations. Besides these factors, the decision-making process of selecting proper land use systems, species and their management practices influenced by socioeconomic factors also resulted in differences in productivity and carbon sequestration potential of systems. | en_US |
| dc.description.abstract | Agroforestry has been recognized as having the greater potential for biomass and carbon sequestration of all the land uses; however, understanding of C sequestration in very specific agroforestry systems is at rudimentary. The present investigation entitled, "Appraisal of carbon sequestration potential of Hardwickia binata Roxb. based Silvopastoral system “was carried out during the year 2016-2017 at silvopastoral system present at research farm of Directorate of Agro-ecology and Environment Centre and Dairy farm, Department of Animal husbandry and Veterinary science, Dr. PDKV, Akola and the laboratory work was carried out at Department of Soil Science and Agricultural Chemistry, Dr. PDKV, Akola. The vegetation study on four species viz., Hardwickia binata Roxb., Stylosanthes hamata, Cenchrus ciliaris and Agave americana L. were carried out for their biomass production and carbon sequestration potential analysis. The aboveground, belowground and total biomass i.e. 77.29, 22.62 and 99.91 t ha-1, respectively, was recorded in silvopastoral system in which trees of H. binata contributed 58.62 % to the total biomass of whole system. By the ash method, the mean organic carbon percent (%) of vegetation was found to be 49.70% i.e. approximately equal to 50% or 0.5 in fraction value. The total carbon density in the whole silvopastoral system was found to be 99.92 t C ha-1 by adding carbon stored in vegetation i.e. 49.86 t C ha-1 (aboveground carbon stock+ belowground carbon stock) and soil carbon density i.e. 50.06 t C ha-1. The litter carbon pool was found to be 0.13 t C ha-1. Soil pH was found to be slightly acidic to neutral in reaction. Soil organic carbon percent was found to be 1.12%. The major available nutrients viz., N, P and K were also significantly influenced by land use systems and altitudinal ranges. Significantly the available N, P, K and S were 325 kg ha-1,66.89 kg ha-1, 526.4 kg ha-1 and 28.62 kg ha-1 respectively, observed under land use system. Among all species, H. binata showed higher available NPK. The conc. of micronutrients i.e. Cu, Mn, Fe and Zn in silvopastoral system were found to be 2.14 mg kg-1, 17.72 mg kg-1, 13.5 mg kg-1 and 2.93 mg kg-1 respectively. In the context of comparative analysis between biomass production of H. binata based silvopastoral system and H. binata block plantation, it was found that the total biomass of silvopastoral system (99.91 t ha-1) was found to be 3 times higher than sole crop plantation of H. binata (33.40 t ha-1). The highest above ground carbon stock (38.62 t C ha-1) and below ground carbon stock (11.24 t C ha-1) was recorded in silvopastoral system as compared to the aboveground carbon stock (13.52 t C ha-1) and belowground carbon stock (3.17 t C ha-1) of block plantation of H. binata. Total carbon stock followed the same trend as above and belowground biomass carbon stock. The soil organic carbon percentage (1.12 %) and soil carbon density (50.06 t C ha-1) of the silvopastoral system was significantly higher than the soil organic carbon percentage (0.55 %) and soil carbon density (22.27 t C ha-1) of block plantation. The total carbon density of whole system (99.92 t C ha-1) and total CO2 sequestered of silvopastoral plot (366.7 t C ha-1) was found to be higher than that of H. binata block plantation (38.97 t C ha-1 and 143.01 t C ha-1 respectively). | en_US |

| dc.theme | Climate changing is already making our planet less inheritable such as increasing greenhouse gases emission among which CO2 emission is of major concern. Stabilizing the climate is perhaps the central challenge for humanity in the early decades of this century. Globally a massive switch to regenerative practices, appropriate technology, tree based land use system, agroforestry practices and regional self-reliance are essential to sequester carbon and reduced emissions. Agroforestry practices is already on the forefront of these efforts, but much more is required. Agroforestry practice is a multipurpose strategy and it have the potential to store carbon and remove atmospheric carbon dioxide through enhanced growth of trees and shrubs. Silvopastoral agroforestry system can incontrovertibly be used as low carbon agricultural technology since it embraces trees with pasture growing for producing quality fodder, increasing farm income and conservation of biodiversity besides offering greater potential of sequestering atmospheric carbon and an almost zero cost approach for restoration of badly degraded land through nitrogen – fixing trees, shrubs and herbs. Therefore, the investigation on carbon sequestration and emission potential of Hardwickia binata Roxb. based silvopastoral agroforestry system and practices currently in vogue is an attempt in this direction. | en_US |
