Abstract

Gunungkidul is one of the regencies at Yogyakarta, Indonesia which is 90% occupied by dry land, and thus vulnerable to climate change impact. Since dryland relies on water only from rain to meet crop water requirement, part of land management is rainfed. This condition encourages farmers to make the right decision regarding their additional income to meet household needs. Under the limited land resources, farmers decided to plant upland rice once or twice a year. The aim of the study is to analyze the interrelationship of households economics activities of upland rice farmers in rain-fed farming based on production, labor allocation, and consumption. The research method is descriptive analysis, with research site Ponjong sub-district, determined by the purposive method. Sampling method using proportional random sampling. Economics model was determined by using simultaneous equation model, with 2 SLS estimation method. The results showed that the household economics model of upland rice farmers in the rainfed land can be explained by using farmers household model and there is a linkage between production, labor allocation, and consumption.
