Israel Finkelstein Paper Suggests LB Collapse In Canaan Fueled by Drought

That’s apparently what the paper says. In any case, since the population of Canaan grew during the Late Bronze collapse [citation not needed], and olives could certainly be grown on the slopes of the hills of Samaria during the Late Bronze Age [citation not needed], in the case of Canaan, it seems that it was the end of Egyptian rule over Canaan and the corresponding sudden shift in social structure that led to the Late Bronze collapse and the revival of olive cultivation there. Things were probably different in the cases of Cyprus and the Alawite coast, and, possibly, the cases of Anatolia and Greece. I still hope to see the results from the Sea of Galilee core-they might be interesting.

See Chronology page for explanation.
Note that the Palestinian climate began worsening in the 23rd century BC and continued to worsen well into 15th century BC. Yet, this period of climatic degradation began with the Three Hundred Years’ Anarchy (as I like to call the Intermediate Bronze Age), continued into a revival of Canaanite civilization between the 19th and 16th centuries BC, and ended with another period of destruction, anarchy, and an end to the vast majority of fortified settlements (the Late Bronze IA).
Also, I corrected the coordinates of the location of the Neolithic settlement of ‘Ain Ghazal, Jordan, on Wikipedia. You have only me to thank for this.
I have also added a Quotes page today.

Those Canaanites…

According to Genesis 10, Canaan was the father of Sidon (Greater (on land) and Lesser (on sea)) his firstborn, and of the Hittites (Indo-European and Canaanite), Jebusites (from Jerusalem), Amorites (most of the Levant), Girgashites (completely unknown, Canaanite tribe), Hivites (Hurrians? probably some Canaanite tribe W. of Jordan), Arkites (Irqata/Arka, 34°31’50″N, 36° 2’48″E), Sinites (Ugaritic Siyannu, at Tell Siyanu, 35°21’56″N, 36° 0’10″E), Arvadites (Isle or Arvad), Zemarites (Amarna Sumur, 34°42’30″N, 35°59’10″E) and Hamathites (Hamah).
