for friendly relations to resume between Turkey and Israel: an apology for the May 2010 Gaza flotilla raid (Prime Minister Netanyahu had delivered an apology to Erdogan by telephone on 22 March 2013), the awarding of compensation to the families affected by the raid, and the lifting of the Gaza blockade by Israel. The Turkish prime minister also explained in the Hürriyet interview, in relation to the April 2013 Gaza visit, "We will monitor the situation to see if the promises are kept or not." At the same time, Netanyahu affirmed that Israel would only consider exploring the removal of the Gaza blockade if peace ("quiet") is achieved in the area. Agriculture Since the beginning of the Israeli–Palestinian conflict, the conflict has been about land. When Israel became a state after the war in 1948, 77% of Palestine's land was used for the creation on the state. The majority of those living in Palestine at the time became refugees in other countries and this first land crisis became the root of the Israeli–Palestinian conflict. Because the root of the conflict is with land, the disputes between Israel and Palestine are well-manifested in the agriculture of Palestine. In Palestine, agriculture is a mainstay in the economy. The production of agricultural goods supports the population's sustenance needs and fuels Palestine's export economy. According to the Council for European Palestinian Relations, the agricultural sector formally employs 13.4% of the population and informally employs 90% of the population. Over the past 10 years, unemployment rates in Palestine have increased and the agricultural sector became the most impoverished sector in Palestine. Unemployment rates peaked in 2008 when they reached 41% in Gaza. Palestinian agriculture suffers from numerous problems including Israeli military and civilian attacks on farms and farmers, blockades to exportation of produce and importation of necessary inputs, widespread confiscation of land for nature reserves as well as military and settler use, confiscation and destruction of wells, and physical barriers within the West Bank. The West Bank barrier With the construction of the separation barrier, the Israeli state promised free movement across regions. However, border closures, curfews, and checkpoints has significantly restricted Palestinian movement. In 2012, there were 99 fixed check points and 310 flying checkpoints. The border restrictions impacted the imports and exports in Palestine and weakened the industrial and agricultural sectors because of the constant Israeli control in the West Bank and Gaza.
