Tackle Climate Change

Reduction in emissions is the key to tackle climate change issues and achieve environmental sustainability. The Gulf Cooperation Council member countries however, not only generate the highest quantity of MSW/capita when compared globally but also in most of these countries such waste is just dumped at different landfill stations. In Oman, the total quantity of MSW stood at 2.0 million tonnes/year. The emission from this waste is estimated at 2,989,467 tonnes/year (CO2 Equivalent). This article attempts to develop frameworks that considered landfilling, composting, and recycling of MSW and compared the emissions of these frameworks. The framework (F2) which proposes the landfilling and composting process for the organic waste which normally goes to landfills results in an increase of emissions by 7% as compared to landfill practice. Similarly, the samples of MSW collected in Oman show a good amount of recycling waste. The framework (F3) which considers the landfill, composting, and recycling reduced the total Greenhouse Gas emissions from 2,989,467 tonnes/year to 2,959,735 tonnes/year (CO2 Equivalent); representing a total reduction of 1% in emissions. Although composting increases the emissions, however, considering composting and recycling will not only reduce the burden on landfills but will promote agricultural and industrial activates.

Composting is an ecological method of recycling organic waste. It presents an effective solution to reduce the large volume of agricultural waste and provides an organic fertilizer and soil amendment. However, its implementation remains limited, especially in Morocco. The vast majority of farmers are unaware of the effectiveness of compost, and it is often considered as an inefficient product compared with chemical fertilizers. In order to develop a local marketing strategy for compost, this study aims to identify the perceptions and willingness of farmers to produce and use compost in agriculture, and to assess the factors shaping these perceptions and willingness, including socio-economic, agricultural and individual factors. The case of Morocco is investigated, where the vast majority of farmers practice inappropriate disposal of agricultural waste and excessive use of agro-chemicals. Data are collected using a standard questionnaire and face-to-face interviews with 350 farmers during their visit to the international agricultural exhibition in Morocco. Descriptive statistics and analysis of variance (ANOVA) are used for data analysis. The results showed a high level (80%) of acceptance by farmers of the production and use of compost. Farmers are also very willing to produce and use compost in agriculture. All the socio-economic, individual and agricultural factors, except gender, length of experience and cultivated area, had a highly significant influence on farmers’ perception and willingness to produce compost (p < 0.005). The positive perceptions of farmers and the high level of willingness to produce compost imply that the composting of organic waste should be encouraged by our local authorities. The production of compost will thus contribute to environmental sustainability and to the promotion of the ecological management of agricultural waste meeting the requirements of a circular economy.

Partners in the implementation of Community Service is the Kembang Lestari Peasant Women's Group located in Taman Village, Abian Semal Subdistrict, Badung Regency.  This group has problems with the high price of chemical fertilizers and vegetable pesticides for the treatment of cultivated crops.  This condition causes an increase in production costs and decreased profits. They have yet to find a solution to get cheaper, environmentally friendly plant-based fertilizers and pesticides that they will use in their organic farms in the future.   Therefore, it is necessary to provide an alternative to organic fertilizers while serving as vegetable pesticides that are easy to make, cheap, and environmentally friendly.  The alternative is an eco-enzyme that can be made from organic waste in the form of fruit peels. Eco-enzymes have the same benefits as liquid fertilizers, compost, anti-bacterial, midges, and disinfectants. Women's Farmer Groups of Kembang Lestari are given knowledge of eco-enzymes and their benefits, how to make and how to apply them to plants.  The methods carried out in the implementation of this activity are by interviewing, face-to-face, counseling, and practice methods directly. First, the authors held general counseling on what an eco-enzyme is, its benefits for plants, and environmental sustainability. Second, the authors provide hands-on training in the manufacture of eco-enzymes and how to implement them and conduct several evaluations to ensure farmers can make eco-enzymes independently and see what percentage of the increased production and increased profits earned by the farmer group after the implementation of these eco-enzymes.   Third, it motivates farmers to keep using eco-enzyme fertilizers continuously in cultivating crops.

The intensifi cation of agricultural production has led to the disruption of nutrient cycles in agroecosystems. In livestock farming, one of the key problems is the low degree of using secondary resources (organic fertilizers based on manure and manure). (Research purpose) To substantiate the basic principles of assessing the agroecosystem environmental sustainability and to develop engineering methods for ensuring environmental safety in livestock farming. (Materials and methods) To solve the problems of agroecological assessment, eff ective technology choice and intelligent system creation, the following indicators were used: 1. specifi c density of animals (mainly for macro-assessment); 2. nutrient balance (the diff erence in the amount of nitrogen available in the formed organic fertilizers with environmentally safe consumption); 3. nitrogen losses during the disposal of organic waste from livestock farming; 4.the eff ectiveness of implementing the best available techniques (BAT). (Results and discussion) Using the assessment of indicators 1 and 2 in the case of the Leningrad region, it was revealed that 3 districts are classifi ed as territories with an excessive risk to the environment, 1 district is classifi ed as a territory with a high risk, 5 districts – with an acceptable risk, and 8 districts – with a low risk to the environment. To solve problems in areas with excessive and high load, we conducted an assessment on indicators 3 and 4, which allowed us to explore technical solutions and select the BAT to reduce the environmental burden. The obtained results showed that among the main technical solutions in the fi eld of organic waste management of livestock farming are biofermentation and the introduction of liquid organic fertilizers. Biofermentation in special chambers can reduce emissions of polluting gases by more than 2 times, and speed up the processing process by more than 60 times. To work with liquid organic fertilizers, intelligent machines with low-emission working bodies have been developed to reduce nitrogen losses during application by up to 50 percent. To solve the problems of agricultural monitoring and engineering solution management, a digital system has been developed that allows to model scenarios of technological development and their impact on the agroecosystem environmental sustainability. (Conclusions) The results obtained allow us to systematically analyze the problems of agroecosystem environmental sustainability and propose specifi c technical and optimization solutions for livestock farming.

The high population growth rate results in an increase in the volume of waste. So far, most people still view waste as useless waste, not as a resource that needs to be utilized. According to SNI 19-3964-1994, municipal solid waste generation is 2 – 2,5 Liters/person/day or 0,4 – 0,5 kg/person/day, small town waste generation is 1,5 – 2 Liters/person/day or 0,3 – 0,4 kg/person/day, the waste generation for large/ metroppolitan cities is greater that 3 Liters/person/day (Center for Resettlement Research an Developmen, 2010). With the reduce, reuse, recycle (3R) program, the amount of waste generation can be reduced. To implement 3R based waste management, the waste reduction process begins with waste sorting. Sorting handling activities according to the type and nature. Based in data from the Balikpapan City Environmental Service, the averange waste production from January 2018 to May 2018 reached 344,73 tons/day. The program for sorting and processing waste from sources is still limited, in Gunung Bahagia Village the success rate has only reached 60%. Waste sorting based on characteristics, the importance of providing understanding and application of waste sorting to the community as a waste producer. Waste sorting is the first step taken to reduce the level of waste in the TPA. Waste sorting should be carried out from waste produciing sources. Waste sorting is carried out based on waste characteristics. Garbage has the characteristics of being easily biogefradable or what is called organic waste, it takes a long tim (years, decades, hundreds of years) to decompose or what is called inorganic waste, waste of hazardous and toxic materials. By sorting waste based on cheracteristics, waste processing can run effectively and efficiently, has econimic value and environmental sustainability. Organic waste has economic value from processing in the form of compost. Inorganic waste has economic value, because this type of waste can be reused and recycled. For hazardous and toxic waste materials, the sorting can reduce environmentals pollution, considering that this type of waste is very easy to react.

In this chapter, the authors explore stakeholders' understanding of what to do with organic waste within the UK. They discuss two projects that were both commissioned and funded under the same government research program specifically to support policymaking. Although looking at the same broad environmental sustainability issue of how to treat organic waste as a resource to be exploited rather than a waste product to be disposed of, the two projects use mapping and involve participants in different ways. Both projects also highlight how the use of quantitative survey data is informed by, and in turn informs, the use of diagrams within the overall methodology. The authors also look at these projects through the different ways diagrams can be used that were discussed in Chapter Two.

Cassava stalk can be converted into sugar-based product by using microorganism. Unfortunately, lignin act as a barrier of optimal bioconversion. Cassava stalk needs pretreatment process for removing this barrier. The effect of lime pretreatment on microstructure of cassava stalk fibers and the growth of Aspergillus niger FNCC 6114 were observed in this research. The cassava stalks were reduced into 0.147- 0.297 mm size and pretreated with 1 % Ca(OH)2. Lime pretreated and unpretreated cassava stalk was used as solid medium for Aspegillus niger FNCC 6114. The effect of pretreatment method on fibers microstructure of cassava stalk was evaluated through SEM micrograph. The growth and metabolism activities of Aspergillus niger FNCC 6114 were monitored through SEM micrograph of media after fermentation. The other parameters examined were changes in glucosamine, reducing sugar levels, and spores’ quantity. Lime pretreatment altered microstructure of cassava stalk fibers. However, cassava stalk without lime pretreatment gave better growth of Aspergillus niger FNCC 6144 based on metabolism activities parameters. Cassava stalks is suitable as media for Aspergillus niger FNCC 6144 through solid state fermentation. For better growth of Aspergillus niger FNCC 6144 fine-sized cassava stalk should not be lime pretreated. The results of this study  provide  information about the pretreatment of cassava stems which was effective in supporting the growth of Aspergillus niger. Enhancements the utilization of cassava stems by using fungi, for example Aspergillus niger can overcome the accumulation of organic waste that can interfere with environmental sustainability.
