In the context of the prolonged Palestinian-Israeli conflict, the Gaza Strip has faced ongoing challenges including several wars, blockades, and severe humanitarian crises. The imposition of the Israeli blockade on the Gaza Strip since 2007 has contributed to dire living circumstances for the Palestinian people. All the literature on this specific issue has concentrated specifically on the effects of the Israeli blockade, and the consequences of wars. This study, however, aims to fill a significant gap in the literature by focusing on the impact of international humanitarian aid on immediate needs and the socio-economic development of the Palestinian people in the Gaza Strip. Adopting a qualitative approach by conducting interviews with representatives of different NGOs; here I use the data collected to gain a deeper understanding of how foreign aid has affected the socio-economic development of the Palestinian people in the Strip and address immediate needs. This study showed that international humanitarian aid positively influences socio-economic development under normal circumstances, fostering small businesses, and mitigating consequences of poverty and stable income. However, during ongoing conflicts a shift towards emergency initiatives becomes imperative. In this study, I conclude that international humanitarian aid is crucial in addressing immediate needs and fostering socio-economic development in the Gaza Strip. It emphasizes the necessity of international efforts to ensure aid access, adherence to international law, and immediate advocacy to alleviate the suffering of the affected population.
