AGROFORESTRY PRACTICES AND ITS CONTRIBUTION TO COMBAT CLIMATE CHANGE IN SUBTROPICAL REGION OF PAKISTAN
SULEMAN SHAH
Abstract
Agroforestry systems could have an indirect impact on C sequestrations by reducing the pressure on natural forests, which are the largest C sink in the terrestrial ecosystem. This research work was conducted in the subtropical region of Pakistan. Tehsil Takht Bhai District Mardan was selected for research study. The geographical coordinates of the study area was 34° 16' 55" North, 71° 55' 42" East. The total area of Takht Bhai is 404 km2 (40,400 ha). Two types of sampling techniques were used for data collection. A questionnaire was compiled for the collection of information on agroforestry practices, while a multi-stage stratified random sampling method was used to collect data and made measurements about carbon contents stored in these agroforestry systems. Total 15 trees species were found associate with agricultural practices belonging to 7 families. 4 species were belonging to Moraceae family. One species belongs to Meleiaceae, Myrtaceae and Simaroubaceae each, 4 species to Fabaceae and 2 species belongs to Rhamnaceae family. Total area under agro-forestry practices was about 22,866.4 hectares. The major agro-forestry system was Agrisilviculture system which was under practice in 11433.2 hectares land area, followed by Silvopastoral system which occupied 6859.9 hectares while area covered by Agrisilvipastoral system was 4573.2 hectares. For obtaining farmers approaches towards different agro-forestry system 275 farmers were interviewed. Through final analysis it was found that 67% farmers were practicing pure Agrisilviculture system, 21% farmers were in favor of Silvopastoral system and 12% farmers were liked to practice Agrisilvopastoral system. The greatest amount of carbon was stored by Silvopastoral system (76.33 t.ha-1) followed by Agrisilvopastoral system which was calculated as (68.05 t.ha-1) while the less not the least amount of carbon stored by Agrisilvicultural system and was calculated as 11.61 t.ha-1.
