The potential loss of rice production due to wetland conversion in East Java
IOP Conference Series: Earth and Environmental Science, 2019
East Java is one of the biggest rice producers in Indonesia. This statement is supported by the availability of wetland resources which are relatively larger than the area of wetland in other provinces. However, over the past few years, East Java is experiencing a significant decline in the wetland area, which can lead to a potential loss of rice production. This research aim to know the aggregate amount of potential loss of rice production that occurred in East Java due to the conversion of wetland. The data used are secondary data from Indonesian Central Bureau of Statistics from 2006 to 2015, including the data of wetland area, rice production and productivity in East Java as well as paddy and rice conversion factors from Food Security and Extension Agency. The method used is descriptive method. The potential loss of rice production can be calculated by multiplying the area of wetlands that are converted with rice productivity, and then the data is adjusted to the available conversion factors. The analysis shows that during the last 10 years there has been a conversion of wetland area of 23.585 hectares in East Java. The loss of wetland area caused the potential loss of rice production is 81.025 tons. The potential for lost production is equivalent to rice consumption for 94.148 people per year in East Java with an average amount of rice consumption of 86 kg per capita per year.

The construction of the Kayu Agung-Palembang-Betung (abbreviated as Kapal Betung) toll road has an impact on changes in the income of rice farmers. The aim of this research was to analyze the changes of farmers' income after converting their non-tidal swamp land to toll road. The research method used in this study is the survey method. In this study the random sampling method used by incidentally. The samples were 60 persons. There was a change in farmers' income before and after converting their rice fields. The livelihoods of postconversion farmers also experience an increase in the variety of occupations. Even though the value of farmers' income after conversion of paddy fields has increased; but this condition needs special attention for policy makers, because of the decreasing number of farmers who will have an impact on national food sovereignty. KEY WORDS Farmers' income change, conversion, non-tidal swamp land, farmer.

Forest region management model in Indonesia applied the separated pattern between forest a real versus non forest areal although a portion of forest area in the form of unoccupied and neglected land already be used to agriculture, plantation, and settlement. The peoples at the surrounding forest regions had been depended of their life on the shifting cultivation pattern to get food during the long time ago. This cultivation cause degraded forest and lose out of the children education. This research was focused to replace the shifting cultivation with settled cultivation in order to minimize degraded forest at the forest regions using the intensive cultivation. The research was located at Mandau Talawang Sub-District, Kapuas District, Central Kalimantan Province, Indonesia at 2010to 2014. Data of paddy yileds from settled cultivation and shifting cultivation were got from 15households were taking by random. Data analysis using the homogenity test, analysis of varians and least signif...
Assessing Land Use Transformation in Kanhangad Town: A Special Emphasis on Wetland Ecosystems
Environment and Ecology Research, 2024
Kerala, renowned for its lush landscapes, is facing environmental challenges due to rapid urbanization, particularly in Kanhangad. This area, notable for its unique wetland ecosystem crucial for biodiversity and human livelihoods, is experiencing a conflict between residential development and wetland conservation. A comprehensive study in Kanhangad, employing diverse data sources such as open-source data, Google Earth Satellite Imagery, OpenStreetMap, and tools like ArcGIS, provides a detailed analysis of land use and its environmental impacts. The study combines digital data analysis with physical surveys to understand the ecological and developmental status comprehensively. The study reveals a dominant trend in Kanhangad's land use, with residential areas comprising 52% of the total land, mostly large, detached single-family homes. This reflects a societal shift towards viewing homes as status symbols, contributing to natural resource depletion. The research underscores the need for sustainable, low-cost housing, suggesting vertical housing as a potential solution to balance residential demands with environmental conservation. Kanhangad's wetlands, essential for local biodiversity and livelihoods, face threats from urban development and infrastructural expansion. The study shows a drastic reduction in wetland area, from 12.9 km² in 2004-05 to just 1.66 km² by 2020-21, indicating severe ecological degradation. Despite the Kerala Conservation of Paddy land and Wetland Act of 2008, which aims to protect these ecosystems, its limited effectiveness is evident from the ongoing depletion of wetlands. This situation calls for stricter enforcement of environmental regulations and greater public involvement in conservation efforts. Furthermore, the research examines the Kerala Paddy and Wetland Conservation Act-2008, analysing its role and effectiveness in local environmental governance. The Act, focusing on prohibiting wetland and paddy land conversion, is vital for regional conservation. However, gaps in its implementation are highlighted, especially considering the exacerbation of the 2018 and 2019 Kerala floods due to land conversion practices. The study emphasizes the urgent need for more robust environmental protection measures
Determinants of Paddy Fields Conversion in Java Island, Indonesia
Proceedings of the International Conference on Science and Technology (ICOSAT 2017), 2018
Rice is a main staple food of Indonesia. Availability of rice is not separated from Java island as the largest rice supplier in Indonesia. Almost 52% of Indonesia's rice production is produced on the Java island. However, production growth is only 0,7% given the increasing number of people. One of the causes is the increasing land conversion over the past 7 years. This study aims to 1) to identify how much land conversion in Java island from 1994 to 2014, 2) to analyze what factors affect the conversion of paddy fields in Java island, and 3) to calculate the impact of paddy field conversion on paddy production and economic value of farmer job for 21 years in Java island. The results indicate that during the period of 1994 to 2014, Java island experienced a conversion of rice fields of 1.2 million hectares or about 60 thousand hectares per year. Productivity of paddy rice, economic growth (GRDP), length of asphalt road, and population growth have significant effect on the conversion of paddy fields in Java island. For 21 years, Java island has lost the opportunity to produce rice by 6.7 million tons with a value of Rp 24,282 trillion rupiah.
