The chief accomplishment of Andriantsitakatrandriana's reign was the initial transformation of the vast Betsimitatatra swamps surrounding the hill of
Analamanga into fertile rice paddies through the construction of dikes. Until his time, only
zozoro (an indigenous sedge), rushes, and clusters of trees grew in the marshy lands around the capital city of
Antananarivo, which his father had at last wrested from its
Vazimba occupants several decades before. After clear-cutting the marshes, Andriantsitakatrandriana ordered the construction of a dike at the southern end of the swamp near Andriantany. The marshes to the west of Antananarivo were the first to be planted as rice paddies. Successive sovereigns would continue this work and progressively transform the entire Betsimitatatra into a continuous patchwork of rice paddies. Oral history relates that Andriantsitakatrandriana devised a ruse to chase his second wife and her son from his territory, although a justification for this uncharitable act is not explicitly stated. According to legend, Andriantsitakatrandriana made an unusual request of his second wife, Rafoloarivo: he asked her to travel to the village of Ambohitrakely to give
hasina to her son (i.e. engage in actions that were believed to multiply his metaphysical worth)—an act that a woman was viewed as unfit to enact for the benefit of a royal male. The queen expressed reluctance to transgress this taboo, but her husband assured her that her concerns should be mitigated by his magnanimous intent to likewise transmit hasina to his first son. He declared that he would reward the queen for her obedience by changing the name of his newly constructed rice paddies from his own name to that of her son. Rafoloarivo complied and departed for Ambohitrakely where she organized a celebration that attracted all the inhabitants of the village of Mahatsinjo. While Mahatsinjo was empty and unguarded, Andriantsitakatrandriana stealthily set fire to the buildings. The distraught populace noticed the blaze and cried out, "Queen, look at this terrible misfortune that has befallen us!" Rafoloarivo and her son escaped the angry crowd and first fled north to
Ilafy, then west and south to Mahatsinjo and Ankosy, all without finding a single person willing to open their doors to the pair. Early in the morning they reached Ambohitrinimanjaka where, at last, the people offered them shelter. Her son, sighting a rocky outcropping in the distance that the locals called Anosivato, declared an interest in continuing to the more distant location, but the queen preferred to remain at Amohitrinimanjaka where Andriamanjakatokana is buried. Locals would traditionally visit the tomb to pray to his spirit whenever a heavy fog descended. The tomb of Andriamanjakatokana's son, also named Andriamanjakatokana, can be visited at Anosivato. ==Death==
