Sealed, stone-built channels that diverted runoff water to exterior channels and moats were in use in cities such as Dan, Tel el-Ajjul, Tel Beit Mirsim, and Gezer.

Wet cultivation was only expanded in the post-independence period. ‘Hill farmers seem to have had little opposition to the clearing of some land for wet rice, even though this has meant that it could no longer be used for dry cultivation. In most villages the areas in which wet cultivation is possible are more or less limited, it never yet having occurred to a Garo that hillsides might be terraced; and the threat of alienation of the land has not yet seemed particularly serious. Strangers, and sometimes even non-Garos, have been allowed to settle and clear new land. At the present time the laws passed by the Garo Hills District Council in an effort to encourage wet rice cultivation provide that if local villagers do not take advantage of suitable land, others will have the right to convert it to paddy fields. In some cases new settlers have probably paid the nokma or even the a’king owners (title-holders) a fee to permit its use and alienation. Some might interpret this as a’wil, the fee that is traditionally paid to the a’king owner by non-villagers who wish to use dry fields, though ordinarily a’wil confers only a temporary right. Others might interpret it as purchase price for the land; or, finally, it might be considered a bribe, since no such purchase is recognized as legal by the government. However regarded, such a fee might help to smooth over any antagonism toward the new arrival, though in practice it appears that the villagers have often failed to appreciate the value of potential paddy land and have let it go with little or no opposition.’ §REF§Burling, Robbins 1963. “Rengsanggri: Family And Kinship In A Garo Village”, 304§REF§ The code reflects dry rather than wet cultivation."

            "description": " 'The Garos may be roughly divided into Hill Garos and Plains Garos, and both classes inhabit the district which owes its name to the tribe.' §REF§Playfair, Alan 1909. “Garos”, 4§REF§ The primary subsistence strategy of the hill country is slash-and-burn/dry cultivation, whereas wet cultivation is practiced in the plains. Wet cultivation was expanded in the post-independence period: ‘There would appear to be somewhat less mutuality in labor exchange in areas of intensive wet rice agriculture. Not only can land be loaned to others on a sharecropping basis, but agricultural labor can sometimes be hired, especially at transplanting and harvest, when the demands of labor are particularly heavy. Labor is also sometimes hired for house-building, a practice unknown in Rengsanggri. Even when labor is given without payment, it is more often calculated and paid back in closely equivalent amounts, and less often given freely, than in the more traditional areas. In some plains areas, unlike Rengsanggri, money is also loaned at interest. Perhaps the relatively diverse origins of the people of wet rice areas makes traditional free labor exchange more difficult. One cannot so easily rely on the ancient bonds of kinship to supply the help that may be needed.’ §REF§Burling, Robbins 1963. “Rengsanggri: Family And Kinship In A Garo Village”, 310§REF§ ‘Hill farmers seem to have had little opposition to the clearing of some land for wet rice, even though this has meant that it could no longer be used for dry cultivation. In most villages the areas in which wet cultivation is possible are more or less limited, it never yet having occurred to a Garo that hillsides might be terraced; and the threat of alienation of the land has not yet seemed particularly serious. Strangers, and sometimes even non-Garos, have been allowed to settle and clear new land. At the present time the laws passed by the Garo Hills District Council in an effort to encourage wet rice cultivation provide that if local villagers do not take advantage of suitable land, others will have the right to convert it to paddy fields. In some cases new settlers have probably paid the nokma or even the a’king owners (title-holders) a fee to permit its use and alienation. Some might interpret this as a’wil, the fee that is traditionally paid to the a’king owner by non-villagers who wish to use dry fields, though ordinarily a’wil confers only a temporary right. Others might interpret it as purchase price for the land; or, finally, it might be considered a bribe, since no such purchase is recognized as legal by the government. However regarded, such a fee might help to smooth over any antagonism toward the new arrival, though in practice it appears that the villagers have often failed to appreciate the value of potential paddy land and have let it go with little or no opposition.’ §REF§Burling, Robbins 1963. “Rengsanggri: Family And Kinship In A Garo Village”, 304§REF§ The code reflects dry rather than wet cultivation."

The long-term causes (the salinisation of agricultural fields, the collapse of the network of irrigation canals, and the decline of the local administrative systems) were combined with the effects of the more recent wars, the political instability, and the invasions. The latter eventually led to famines and epidemics, a drastic reduction of the population, and low birth rates.\" §REF§(Liverani 2014, 469)§REF§ \"Ruins of reservoirs have been discovered along with water intakes, spillways and outlets and even the sewerage systems dating as far back as the Pre-Archaemenid and Assyrian (1500-600 BC) periods.\" §REF§(Mahmoudian and Mahmoudian 2012, 97) Angelakis A N, Mays L W, Koutsoyiannis, D. 2012.Evolution of Water Supply Through the Millennia.
