“…Many studies also employed CVM to quantify the benefits of nonmarketed environmental goods and attributes in such a way that they can enter directly into cost-benefit calculations predominantly in western, North American and East Asian advanced and developed countries (Carson et al 2010). The CVM methodology highlights diverse issues like improvements in water quality and sanitation (Howard et al 2010;Vörösmarty, et al 2010;Orgill et al 2013), valuing forestry (Canadell and Raupach 2008;Gelo and Koch 2012;Mason et al 2013), exposure to flood risk (Lantz et al 2012;Kellens et al 2013), wetland conservation (Yoon 2009;Kaffashi et al 2013;Turner 2013), offsetting carbon emissions and groundwater contamination, health economics (Georgiou and Turner 2012;Del Borghi et al 2013;Everard et al 2013;Andersson et al 2014), cultural economics (Carvalho et al 2010;Wicker et al 2012), transportation safety and economics (Hess et al 2012;Kristiansen 2013) and a wide range of environmental services (Ojeda et al 2008;Vo et al 2012).…”

This paper estimates Malaysian farmers' willingness to pay (WTP) for a planned adaptation programme for addressing climate issues in the Malaysian agricultural sector. We used the contingent valuation method (CVM) for a monetary valuation of farmers' preferences for a planned adaptation programme by ascertaining the value attached to address climatic issues in the Malaysian agricultural sector. Structured questionnaires were distributed among the sampled farmers. The study found that 74 % of respondents were willing to pay for a planned adaptation programme and that several socioeconomic and motivation factors have greater influence on their WTP. This paper clearly specifies the steps needed for all institutional bodies to better address issues in climate change. The outcomes of this paper will support policy makers to better design an efficient adaptation framework for adapting to the adverse impacts of climate change.

“…Pertanian berkelanjutan telah menjadi isu sentral pembangunan berkelanjutan yang menyangkut pengembangan sistem manusia-lingkungan yang kompleks (Pollock et al 2008;Wu et al, 2010). Dalam hal penggunaan lahan untuk sawah, karena pentingnya perannya sebagai pemasok pangan, penggunaan lahan perlu dilakukan secara bijaksana (Yoon, 2009;Kim et al, 2006).…”

Indonesian national food sovereignty is very dependent on the supply of rice from paddy fields in Java Island. Various factors influence the farmer's decision to continue using his farm. This study aims to analyze the sustainable use of paddy field, determinant factors and strategies for improving sustainability. The study was conducted in Karawang Regency, one of the centers of rice production in West Java. The methodology used is a multi-dimensional scaling (MDS) using 43 attributes of 5 dimensions (ecological, social, economical, technological and legal and institutional dimension). Against the sensitive attribute analysis resulting from MDS, a prospective analysis was conducted to determine the key factors of sustainability. Priority policies for improving sustainability are developed based on the location of the key factors in the prospective diagram. The research results showed that the land utilization for paddy field in Karawang is actually less sustainable. Increasing the sustainability can be done through intervention and improving performance, preferably on sensitive attributes resulting from leverage analysis, covering 16 attributes. Priority policies is directed in the 5 key factors resulting from prospective analysis. Policies suggested are the tightening of new permits for building, strict implementation of the official spatial land use planning and delineation of agricultural land for sustainable food crops, counseling the community, revitalizing the role of BULOG, provision of subsidies as well as capital assistance to farmers.

“…However, since in most cases only effects shortly after land use changes were studied, it is not clear if the related changes were caused by the type of management or rather reflected a response of microbial communities toward the disturbance of a balanced ecosystem. To address this question, we compared four paddy soils that have been cultivated with rice for different time periods (50 to 2,000 years) with a tidal wetland, which typically represents the parent material for agricultural land reclamation in China (39).…”

In many areas of China, tidal wetlands have been converted into agricultural land for rice cultivation. However, the consequences of land use changes for soil microbial communities are poorly understood. Therefore, we investigated bacterial and archaeal communities involved in inorganic nitrogen turnover (nitrogen fixation, nitrification, and denitrification) based on abundances and relative species richness of the corresponding functional genes along a soil chronosequence ranging between 50 and 2,000 years of paddy soil management compared to findings for a tidal wetland. Changes in abundance and diversity of the functional groups could be observed, reflecting the different chemical and physical properties of the soils, which changed in terms of soil development. The tidal wetland was characterized by a low microbial biomass and relatively high abundances of ammonia-oxidizing microbes. Conversion of the tidal wetlands into paddy soils was followed by a significant increase in microbial biomass. Fifty years of paddy management resulted in a higher abundance of nitrogen-fixing microbes than was found in the tidal wetland, whereas dominant genes of nitrification and denitrification in the paddy soils showed no differences. With ongoing rice cultivation, copy numbers of archaeal ammonia oxidizers did not change, while that of their bacterial counterparts declined. The nirK gene, coding for nitrite reductase, increased with rice cultivation time and dominated its functionally redundant counterpart, nirS, at all sites under investigation. Relative species richness showed significant differences between all soils with the exception of the archaeal ammonia oxidizers in the paddy soils cultivated for 100 and 300 years. In general, changes in diversity patterns were more pronounced than those in functional gene abundances.
