Carbon sequestration and greenhouse gas emissions for different rice cultivation practices

چکیده

Traditional rice farming systems require large amounts of water for irrigation, labour transplanting culms and tending fields, therefore, emit greenhouse gases such as carbon dioxide (CO2), nitrous oxide (N2O) methane (CH4). Adopting alternative practices could reduce gas emissions increase (C) sequestration. In this study, an on-site field experiment was conducted to assess the contribution by farm operations involved in three types cultivation practices: conventional (CVN), system intensification (SRI), zero-tillage (ZTL). The study aimed examine indices under different methods ecosystem services disservices associated with sequestration emission. Results showed that fertilizer application significantly contributed GWP among cultivations. CVN ZTL plots, higher CH4 N2O.

Monitoring Carbon Sequestration and Greenhouse Gas Emissions from Irrigated AgroEcosystems

Conventional field cropping systems have been criticized as being unsustainable because they contribute to on-farm and off-farm environmental degradation, and are often economically uncertain. Methods to increase environmental and economic sustainability are needed. There is a critical need to develop management technologies to maximize yield and crop quality yet improve environmental impacts o...

Greenhouse gas emissions from rice

Rice provides the staple food for over 60% of the world’s population. Globally 80% of rice is grown by small farmers in low income and developing nations, and in India rice farming is a key source of employment for the 60% of Indian workers still dependent on agriculture for work. Yet rice production is also an important source of greenhouse gas emissions, for example responsible for between 3 ...

Rice Cultivation and Greenhouse Gas Emissions: A Review and Conceptual Framework with Reference to Ghana

Rice is an essential crop in Ghana. Several aspects of rice have been studied to increase its production; however, the environmental aspects, including impact on climate change, have not been studied well. There is therefore a gap in knowledge, and hence the need for continuous research. By accessing academic portals, such as Springer Open, InTech Open, Elsevier, and the Kwame Nkrumah Universit...

Greenhouse gas emissions - do carbon taxes work ?

During the last decade, Norway has carried out an ambitious climate policy by implementing a relatively high carbon tax already in 1991. The Norwegian carbon taxes are among the highest in the world. Data for the development in CO2 emissions provide a unique opportunity to evaluate carbon taxes as a policy tool for CO2 abatement. We combine a divisia index decomposition method and applied gener...
