The REGFLUD-project, commissioned by Germany's Federal Research Ministry (BMBF), addresses the problem of reducing diffuse pollution from agricultural production. The objective of the project is the development and application of multi-criteria scientific methods, which are able to predict diffuse pollution in river basins subject to economic feasibility and social acceptability. The selected river basins (Ems and Rhine basins) cover a variety of landscape units with different hydrological, hydrogeological and socio-economic characteristics. This paper focuses on the analysis of the effects of certain policy measures to reduce diffuse pollution by nitrogen. For this purpose a model system consisting of an agricultural sector model, a water balance model and a residence time/denitrification model was developed and applied. First results indicate a wide range of annual nitrogen surpluses for the rural areas between less than 10 kg N/ha up to 200 kg N/ha or more depending on the type and intensity of farming. Compared to the level of nitrogen surpluses the level of nitrogen inputs into the surface waters is relatively moderate because of degradation processes during transport in soil and groundwater. Policy impact analysis for a nitrogen tax and a limitation of the livestock density stress the importance of regionally tailored measures.

During the period from 2006 to 2011, 80 frontline demonstrations were conducted on the horsegram production technology to transfer the technologies among the farmers of Bhilwara district in semi-arid region of south Rajasthan with the objective to evaluate the economic feasibility of technology transfer and adoption. Adoption of improved technology had significant impact on seed yield vis-a-vis yield gaps in horsegram. Improved technology enhanced horsegram yield from 294 kg/ha (farmer’s practice) to 537 kg/ha (improved practice), an overall increase of 40.83%. There was a wide yield variation between potential and demonstration yields of horsegram mainly due to technology and extension gaps. Extension yield gaps varied to the extent of 96 to 180 kg/ ha whereas technology yield gaps varied from 288 to 413 kg/ ha. Technology index varied from 34.91 to 50.06 %, which indicate for further scope of improvement in productivity of horsegram in the region. The marginal difference between benefit-cost ratio of improved practice and farmer’s practice proves of adoption of improved technologies by the farmers. However, to further bridge up the gap between technology developed and technology transferred, there is a need to strengthen the extension network besides emphasis on specific local recommendations.

Despite the steady growth and price reductions of solar photovoltaic (PV) market in the United States (U.S.), the solar PV market still depends on financial support and incentives due to its high initial investment cost. Therefore, this study aimed to conduct a break-even analysis and impact analysis of residential solar PV systems by state in the U.S., focused on state solar incentives. Three indexes (i.e., net present value, profitability index (PI) and payback period) were used to evaluate the investment value of the residential solar PV systems considering state solar incentives. Furthermore, PI increase ratio was used to analyze the impact of state solar incentives on the economic feasibility of the residential solar PV systems in each state. As a result, it was found that 18 of the 51 target cities have reached the break-even point and seven of the 51 target cities showed great improvement of the economic feasibility of solar PV systems in the U.S. due to excellent state solar incentives. The results of this study can help policy makers to evaluate and compare the economic impacts of the residential solar PV systems by state in the U.S.

Macro-algae flora of the mussel culture zones in Gouqi island, Zhejiang Province, was surveyed from 2014 to 2015. Seventy species of macro-algae were identified, belonging to 31 genera, 21 families, 14 orders, and three phyla. Thirty-eight species from 16 genera belong to Rhodophyta, 21 species from seven genera belong to Phaeophyta, and 11 species from eight genera belong to Chlorophyta. Rhodophyta, Chlorophyta, and Phaeophyta contributed to 54.29%, 30%, and 15.71% of the total number of species, respectively. The dominant species were Undaria pinnatifida, Sargassum horneri, Grateloupia livida, Grateloupia turuturu, Ulva pertusa, Ulva lactuca, Hypnea boergesenii, Ulva linza, Cladophora utriculosa, and Amphiroa ephedraea. Seasonal alternation of macro-algae species was evident; there were 52 species in spring, 42 species in winter, 38 species in autumn, and 30 species in summer. Macro-algae biomass was highest in spring and lower in autumn > summer > and winter. The diversity of macro-algae communities also changed seasonally; the diversity index (H’) was highest in autumn and lower in summer > winter > and spring. The results of de-trended correspondence analysis suggested that temperature was the most important environmental factor affecting the distribution of the macro-algae in mussel culture zones. Wind, water currents, and human disturbances were also important factors affecting algal communities.

The article presents economic feasibility evaluation for using high-priced drugs in the regimens for treatment of tuberculosis patients with extensive drug resistance.Subjects and Methods. Treatment efficiency was evaluated in 175 tuberculosis patients with extensive drug resistance, treated by four different regimens, including third line drugs and without them; the economic impact of each regimen was evaluated. Two types of pharmaco-economic analysis were used: costs – effectiveness and budget impact analysis.Results of the study. Despite the significant costs of regimens containing moxifloxacin, linezolid, and bedaquiline, the co-efficient of costs – effectiveness turned out to be the lowest. When using models for comparing costs and losses over 5 year period of XDR TB patients treatment it was found out that regimens containing moxifloxacin, linezolid and bedaquiline possessed significant economic predominance which required major investment at the initial stages of introduction, and by the end providing savings from 46.3 to 65.3% of the budget compared to the regimens without these drugs. The obtained results provide the evidence that use of regimens containing new highly effective drugs (moxifloxacin, linezolid and bedaquiline) in rational combinations with basic and reserve drugs, prescribed with consideration of drug resistance profile allow achieving the significant economic effect.

Abstract PV system is an eco-friendly option to meet the need for energy due to its lower carbon footprint when compared to the fossil-fueled power plants. In this research, we performed techno-economic and regulatory impact analysis on a rooftop PV system on a mosque in Purworejo, Indonesia under a net metering mechanism. The use of PV system on the mosque rooftop can reduce its entire carbon emission from its annual energy usage, which equals to 4 tonnes of carbon dioxide equivalent. However, the economic feasibility of the PV systems, measured by the NPV of the electricity bill saving, shows negative values for all PV system configuration, defined by the type and number of panels. This low financial attractiveness is resulted from several unsupportive regulations: the subsidized electricity tariff, the minimum grid electricity usage limit and the less rewarding net metering scheme. The abolishment of minimum usage limit incurs the greatest increase of NPV to the PV system that is designed to entirely supply the load demand. While the implementation of higher electricity tariff incurs the highest increase of NPV for the PV systems with partial supply scenario. This study shows that at the current electricity tariff, costs of components, and the implemented regulations around the adoption of PV system, it is financially unfeasible to install a PV system on the mosque rooftop.
