Abstract

Accurate information of paddy fields over wide areas is essential to support sustainable agricultural and a food security program. Monitoring of these lands continuously, using remote sensing technology, will provide information related to the cropping intensity in the field, as well as its dynamics change. We characterized seasonal vegetation dynamics from long-term multi-temporal MODIS satellite datasets in order to determine cropping intensity and to analyze the dynamics change in paddy field of Java. The results indicate that the methodology employed in this research distinguished many specific uses in paddy fields as means of their cropping intensity. Moreover, the seasons were the most important factor affected the dynamics change in the agricultural system. Extreme climate variability caused many paddy fields, especially in non-irrigated land, to remain barren as well the planting time was postponed. Indeed, characterizing the long-term vegetation dynamics of paddy field provides information about the characteristics and trends in these land use types, either caused by natural factors or human activities.

Highlights

Information on agricultural land use over wide areas is essential to support sustainable agriculture and a food security program
According to [3], about 70.62% of Java is considered to be agricultural land use; paddy fields, mixed gardens, uplands/dry lands, open grass, fishponds, and plantations, with as much as 5.43% of the area covered by settlements
The number of cultivation cycles in paddy fields that occur yearly depends on the availability of water, and regarding the EVI patterns, the rice paddy fields in Java could be sorted into several types of cropping systems

Summary

Introduction

Information on agricultural land use over wide areas is essential to support sustainable agriculture and a food security program. As population growth drives demand for food, at least agricultural production must be increased following the rate of population growth; otherwise, there is a need to import food to fulfill those demands [1,2]. The Indonesian government estimates that its people rely on rice for roughly 40%–50% of their daily protein and caloric requirements, respectively [3]. For Indonesia’s population of more than 237 million people, the status of its domestic rice supply is synonymous with its food security [1]. Understanding the potential production of paddy fields accurately including its future trends is necessary to improve the effectiveness and efficiencies of the agricultural land development programs
