  Energy consumption is increasing rapidly in the world and it is expected that unrenewable energy sources will expire in the future; therefore, new methods of energy production are becoming more common all over the world. Biogas is one of the new and clean energies, which is produced from anaerobic fermentation of biomass. Guilan province with 238,000 hectares of paddy lands has significant potential for biogas production from organic residues. In this way, this study was carried out to investigate the process of biogas production from the combination of rice straw and animal waste with the ratios of (0-100), (5-95), (10-90), (15-85), (20-80) respectively in three repetitions. The experiment was performed at mesophilic temperature by anaerobic digestion method in the 1/5 lit bottles. An economic and environmental assessment for replacement of biogas produced in this process with fossil fuels was implemented in the village of Pounel in Guilan Province. The results showed that the ratio of 10% of rice straw had the highest biogas production efficiency and by replacing the biogas, 21 percent will save in fossil fuel consumption. It will also prevent the emission of 328.42 kg of CO2 gas into the atmosphere per year. Manuscript profile

  Water is one of the problems of today's world and it is necessary to conserve it. Many parts of the world are facing drought conditions. The purpose of this research is to analyze new and different techniques in modern agriculture. In this regard, it has been tried to introduce new methods using super absorbents. With the advancement of science and technology, excellent polymer materials have been developed to retain water. In this article, water retention agents based on natural and synthetic polymers have been reviewed in the last 10 years. Finally, the synthesis of two types of natural and synthetic super absorbents using recycled materials is described. Hydroxyethyl cellulose has excellent characteristics of a superabsorbent such as being biodegradable, non-toxic, high water absorption, and is one of the derivatives of cellulose, which is used in water extraction, wastewater treatment, electrolytic membranes, pharmaceuticals, and pesticides. Alternative soil has many applications in agriculture. And its use can be expanded by combining with different polymers. This combination allows the formation of new biomaterials with improved properties and various applications. As a result of preparing a water retention agent with a practical perspective in agriculture, it not only enhances water absorption and water retention in the soil, but also is resistant to salinity and has mechanical strength, re usability and economic value. is. All these features are present in the introduced super absorbents. Manuscript profile

  During the last century, science and technology have grown and developed significantly, however, this development, along with all the advantages and added values for the quality of human life, has brought inappropriate effects on the environment. Unfortunately, the human conflict with the problems which has created for the planet, including wars and new diseases, has caused less attention to the impact of climate change on environment and especially the related agriculture activities. If the agricultural sector exposed by climate change and will not be able to meet human food needs, life will be near to its end point. Agricultural activities are not only exposed to these changes, but also by leaving possible negative effects on environment lead to these changes. Threatening food security, the reduction of biological diversity, the loss of soil, the reduction of water resources, and the conversion of forests into farms and their gradual destruction, turn the earth into an unlivable area with the unpredictable occurrence of storms, floods and temperature changes. Therefore, investigating the impact of climate change and its components on different ecosystems and species that affect agriculture can be a step towards achieving new management mechanisms to reduce and adapt to these changes and achieving sustainable environment and agriculture.
