This paper aims to analyze Samih Al-Qasim's conceptions of land as manifested in his poetic discourse of eco-resistance from an ecopostcolonial perspective by drawing heavily on Graham Huggan and Helen Tiffin's postcolonial, ecocrtical theory and Mita Banerjee's conception of land witnessing. The paper also attempts to show which of A-Qasim's conceptions of land is given prominence in his poetry. Through the analysis of Al-Qasim's poetic treatment of the Palestinian land, four conceptions of land prominently emerge: land as a source of belonging, land as a witness to the scenes of devastation and the suffering of the Palestinian people, land as a form of resistance and land as a target of colonial exploitation. Al-Qasim gives the first priority to his illustration of the land as a source of belonging. The second priority goes to his conception of the land as a witness to the Palestinian suffering and the scenes of destruction. By focusing on these two priorities, Al-Qasim reveals how the land is approached differently by the colonized Palestinians and the Israeli occupiers.
