| Summary: | Availability of irrigation water causes changes occur in the cropping pattern and
cropping intensity. These changes will lead to changes in the use of farm inputs which in
turn will lead to changes in income, and the possibility of changes in income distribution.
This study aims to analyze: (i) the effect of irrigation on cropping intensity, (ii) the effect of
irrigation on rice production, (iii) the effect of irrigation on paddy rice farm income, (iv) the
effect of irrigation on income distribution lowland rice farming, (v) influence on the
distribution of irrigated rice land tenure, and (vi) the effect of climate change on planted
area, production and productivity of paddy rice.
The basic method used in this research is descriptive analytical method. The
experiment was conducted at the Pekik Jamal Irrigation Area that was in Kulon Progo
Regency, Yogyakarta Province. The type of data used is primary data, interviews with
farmers using a sample list of questions that have been prepared and secondary data years
1980 - 2011 in the form of rainfall, acreage, production, and productivity. The analytical
method used is multiple regression analysis and trend.
The results showed that the Irrigation yell Jamal increase cropping intensity. Upland
irrigated rice cropping intensity 31% higher than the downstream. While in the nonirrigated
rice field area 84% higher. Production of paddy rice farming is affected by the use
of chemical fertilizers (Urea, TSP, KCl, ZA, and Ponska) and the use of human labor (labor
within the family and outside the family labor). Rice production on irrigated land is higher
than the 0.44% non-irrigated paddy production (rainfed) rice production and farmers in the
irrigated areas upstream 0.53% higher than the farmers in irrigation areas downstream.
Factors that affect the paddy rice farm income was broad land, the price of chemical
fertilizers, machinery and labor. Income of farmers on irrigated land is 0.76% higher than
the income of farmers in non-irrigated paddy fields (rainfed) and income of farmers in the
irrigated areas upstream 0.88% lower than the farmers in irrigation areas downstream.
Furthermore, the distribution of income and tenure paddy farmers in irrigated fields
more evenly distributed when compared with rainfed land (non-irrigated). Gini ratio value
of rice farming income on irrigated land and 0.7133 for non-irrigated paddy fields (0.7081)
while the value of Gini ratio of land tenure on land irrigated paddy rice fields 0.7087 and
non-irrigated (0.6869). Thus, improving irrigation paddy rice farming income distribution
and the effect on the distribution of paddy land tenure. During the period 1980-2011 there is
an increase in harvested area, production and productivity of paddy rice. The more extreme
type of climate will adversely affect the harvested area, production and productivity of
paddy rice.
