the kibbutzim in Israel experienced during the 1980s, many kibbutzim began adopting an action-oriented market economy and concluded that basing the economy on the volunteer workforce was not a profitable model. Meanwhile, some kibbutzim gradually began to employ foreign workers from Thailand in the agricultural sector of the kibbutz and Israeli workers in the industrial and services sectors. Following the intensification of the Israeli–Palestinian conflict during the last decades of the 20th century, and in particular after the Second Intifada started in 2000, many countries ceased to cooperate with the project and as a result there was a significant decrease in the number of the kibbutz volunteers. The decrease hit its lowest point in 2001, when only 100 volunteers arrived in Israel. In recent years, there has been a slight increase in the number of volunteers, and in 2007 approximately 1,500 kibbutz volunteers came to Israel. In total, 350,000 volunteers from 35 different countries have volunteered in various kibbutzim in Israel since 1967, with most of the volunteers through the years coming from the United Kingdom (circa 50,000), South Africa (circa 40,000), Sweden (circa 25,000), Denmark (circa 20,000), and Germany (circa 15,000).
