  • An applicability test of the use of deposit-refund system for managing
           water-sachet litter in Ilorin, Nigeria

    • Abstract: This study used both quasi-experiment and contingent valuation survey to explore the applicability of deposit-refund system (DRS) to water-sachet litter management in Nigeria. In the experiment, a DRS was established to incentivize the participants to return emptied sachets of water. A contingent valuation survey of 454 sachet-water consumers selected using quasi-systematic sampling technique was conducted. Experimental results showed that the number of sachets returned by the experimental group – those subjected to DRS – was significantly greater than that of the comparison group – those not subjected to DRS. Logit regression results showed that refund size increased the odds of returning sachets by 42.0%. Increasing the redemption time decreased the odds of turning in sachets by about 16.0%. A one-minute increase in the time spent on redemption would result in about 2.4% decrease in the probability that participants would comply. Income decreased the odds of compliance by about 31.0%, while age reduced the odds of compliance by about 2.2%. These results imply that the DRS reduced water-sachet littering in the study area, and that income, refund amount, redemption time, age and perceived effectiveness of DRS influenced consumers’ compliance with DRS. Hence, an appropriate motivating DRS would reduce litter and its attendant problems, such as hygiene, plastic pollution, flooding, aesthetic loss, non-naturally degradable toxic compounds, degradation of natural habitat ant its endangered species. The government should, therefore, implement a DRS and set up recycling plants, or encourage private recycling firms, in order to accommodate used sachets that would end up piling up.

  • A review on household energy consumption behavior: how about migrated
           consumers'

    • Abstract: This paper reviews the literature on energy consumption behavior for both domestic and migrated/displaced population and aims to recommend crucial policy measures for creating awareness on the energy efficiency. Consumers’ adoption to the efficient usage of energy varies depending on demographic, behavioral and situational dynamics in their households and societies. The regional or national strategies to implement efficient technologies for the consumer engagement are crucial to change their behaviors. Migrants affect the energy usage patterns in the host country due to their different usage behaviors. Any type of measures for migrated population should include available, acceptable, accessible and affordable energy efficiency applications to engage them with the domestic population.

  • Assessment of ecological and economic efficiency of agricultural lands
           preservation

    • Abstract: The article substantiates the necessity to define and generalize the criteria for assessing the ecological and economic efficiency of using agricultural lands. Due to the transition of the agro-industrial complex to private forms of management, the problems of forming a strategy of rational, ecologically safe and sustainable development of land use in Ukrainian agriculture became of paramount importance. Therefore, systematic studies on the assessment of the ecological and economic efficiency of the agricultural land use need to be conducted. Harmonization of ecological and economic interests is of particular importance in the context of ensuring the conservation, resource-saving and reproductive nature of the agricultural land exploitation.A scientific study found that in Ukraine, the agrarian sector of the economy provides about 47% of GDP, but the question arises: At what price are these achievements given to us' Agricultural land development exceeds environmentally sound standards. Excessive cultivation of the territory leads to an annual increase of eroded lands by 80-90 thousand hectares. Land use is recognized as environmentally unstable, and there is a steady tendency to deteriorate the quality of soil. Each second hectare of cultivated land is erosion-hazardous, that is, these soils are subject to water and wind erosion. In this regard, it is recommended to introduce the world-wide experience of Climate Smart Agriculture (CSA), which provides an opportunity to provide food security to the country and to limit the negative impact of the environment, based on the introduction of organic production.It is proved that regardless of the size of farms and forms of management using resource-saving no-till technologies, enterprises received low cost of grown products, providing profitable activities. Ecological compatibility of the technology provides energy savings of at least 30% in comparison with traditional farming systems, the accumulation of not less than 30-40% of plant residues on the soil surface after harvesting of the predecessor, provides protection of the soil from wind and water erosion by minimizing the amount and depth of technological operations.It is confirmed that the most widespread evaluation of the agricultural lands use is the evaluation of the results of their use through volumes of gross and commodity products, income, and production profitability. The criteria for the environmental effectiveness of agricultural land use should be: the degree of functional use of land resources, ecological stability, the level of anthropogenic loading, the degree of erosional feature of land, etc.According to the study results, it was established that one of the main areas of agriculture is the application of minimal tillage in crop rotation, i.e. resource-saving no-till technology.The economic feasibility of technologies based on the use of different soil tillage systems has been confirmed.
