Pakistan Experience in Dryland Afforestation

Pakistan Experience in Dryland Afforestation

K. M. Siddiqui and B. H. Shah

ABSTRACT

Pakistan has a long history of and vast experience in the practice of dry affoestaiton because about 60-70% area in arid and semi-arid parts in Pakistan is subjected to desertification to varying degree for climatic reasons and due to misuse of land for agricultural and pastoral purposes over a long period of time. A number of government agencies have been engaged in the afforestation of vast dry areas in the country. Most of the efforts in this regards have so far been patchy, sporadic and scattered, and ware therefore, impact over a long period in the face of increasing pressure of growing human and cattle population. The Pakistan Forest Institute started systematic research on efficient use of available rain water for dryland afforestation in the 1980's under PL-480 Assistance Programme of the Pakistan Agricultural Research Council and USAID Forestry Planning and Development Project on both public and private lands. A number of water conservation, harvesting and planting techniques were investigated for the establishment of tree plantations in the dry regions. The roaded catchments, microcatchments, and individual basins proved effective and economical for dry affoestation. Plastic mulching, drip irrigation, pitcher irrigation and deep planting were also successfully used for this purpose. A number of multipurpose tree species adapted to the desert environmental conditions in Thal were identified. These were Acacia albida, Acacia tortilis, Acacia elata, Tecoma undulate, Acacia victoriae, Tamarix aphylla, Acacia modesta, and Prosopis cineraria. For semi-arid area of Kharian, Eucalyptus camaldulensis, Acacia saligna, Acacia elata, Acacia albida and Leucaena leucocephala were found to be quite successful.
