A sign posted a few kilometres north of Beersheba, the Negev's main city, announces plans to plant a total of a million trees over a large area of desert that has already been designated "God-TV Forest".
The Jewish National Fund, an international non-profit organisation in charge of forestation and developing Jewish settlements in Israel, received $500,000 from God-TV to plant some of the trees, according to the channel's filings to US tax authorities last year.
A coalition of Jewish and Bedouin human rights groups have denounced the project, accusing God-TV and the JNF of teaming up to force the Bedouin out of the area to make way for Jewish-only communities.
Standing next to the "God-TV Forest" sign, Alec thanked thousands of viewers for making donations to "sow a seed for God", adding: "I tell you Jesus is coming back soon!"
Part of the forest has been planted on land claimed by the Aturi tribe, whose village, al-Araqib, is nearby.
Al-Araqib has been demolished eight times in recent months by the Israeli police as officials increase the pressure on the 350 inhabitants to move to Rahat, an under-funded, government-planned township nearby.
Earlier this year, Joe Stork, the deputy director of Human Rights Watch's Middle East and North Africa division, criticised the repeated attempts by Israeli authorities to eradicate the village and displace its residents.
"Tearing down an entire village and leaving its inhabitants homeless without exhausting all other options for settling long-standing land claims is outrageous," he said.
Human Rights Watch and other international human rights groups have criticised Israel for harsh measures taken against the people of al-Araqib and the other 90,000 Bedouin who live in Negev villages that the Israel refuses to recognise. They accuse the government of trying to pre-empt a court case moving through Israeli courts aimed at settling the Bedouin ownership claims.
God-TV's involvement in the dispute has prompted fresh concern.
Neve Gordon, a politics professor at Ben Gurion University in Beersheba, said the JNF, which has semi-governmental status in Israel, had set a "dangerous precedent" in accepting money from God-TV.
"The Israeli authorities are playing with fire," he said. "This dispute between the Israeli government and the Bedouin is a long one that until now focused on the question of land rights. But the involvement of extremist Christian groups like God-TV is likely to turn this into a religious confrontation, and that will be much harder to resolve."
The JNF did not respond to questions about its involvement with God-TV or the Negev forest.
Gordon said it was particularly worrying that Alec was using the language of Biblical prophecy in justifying his decision to finance the forest.
