Water eutrophication caused by agricultural production has become one of the most important factors that impede sustainable rural environmental governance in China. As a result, the Chinese central and local governments want to reduce the use of nitrogen and phosphorus fertilizer and gain socioeconomical profit simultaneously by promoting crayfish and rice integrated system (CRIS) in the rural areas with abundant water resources. In this article, we investigated whether CRIS in Qianjiang, Hubei, the origin place of the system in China, contributes to fulfilling the governments’ expectations. We found that CRIS efficaciously cuts the fertilizer rate in rice production and boosts farmers’ incomes because crayfish has a demand for water quality and holds a large internal market requirement. However, higher profit encourages farmers to expand crayfish production and thus discourages the initiatives in rice production. The area of the ditch for crayfish production expands ceaselessly and exceeds the limit of regulation of CRIS. As a result, the CRIS in the areas has emerged as a practice of aquaculture but in farmland. This is a regulatory gap. The input–output analysis of CRIS by material balance method can also reveal that excessive feed for crayfish has become a new source of agricultural pollution. Beyond that, due to the changed irrigation system and increased water exchange frequency of CRIS, the pollution has transformed from passive distribution to active, which will increase the risk of water eutrophication on a large area.

China was the first developing country to achieve the poverty eradication target of the 2030 Agenda for Sustainable Development Goals (SDG) 10 years ahead of schedule. Its past approach has been, mainly, to allocate more fiscal spending to rural areas, while strengthening accountability for poverty alleviation. However, some literature suggests that poor rural areas still lack the endogenous dynamics for sustainable growth. Using a vector autoregression (VAR) model, based on data from 1990 to 2019, we find that fiscal spending plays a much more significant role in reducing the poverty ratio than agricultural development. When poverty alleviation is treated as an administrative task, each poor village must complete the spending of top-down poverty alleviation funds within a time frame that is usually shorter than that required for successful specialty agriculture. As a result, the greater the pressure of poverty eradication and the more funds allocated, the more poverty alleviation projects become an anchor for accountability, and the more local governments’ consideration of industry cycles and input–output analysis give way to formalism, homogeneity, and even complicity. We suggest using the leverage of fiscal funds to direct more resources to productive uses, thus guiding future rural revitalization in a more sustainable direction.

Many Indonesians—primarily those living in rural areas—still follow customary law (adat). The precise rules and processes of that adat differ significantly from place to place, even within short distances. This chapter shows that for many decades, adat has been subservient to national law. State-made law overrode it, leaving it applicable only in a very small proportion of cases where no national law applied, where judges could apply it as ‘living law’. Even in these cases, many judges ignored adat or distorted it when deciding cases. The 1945 Constitution was amended in 2000 to require the state to formally recognize and respect customary law, as practised in traditional communities. The Constitutional Court has given effect to this in various judicial review cases, as have some statutes enacted in the past decade or so. However, this constitutional and statutory ‘protection’ has been impeded in practice by requirements for traditional communities to be formally ‘recognized’ by their local governments, many of whom have been unresponsive to calls for recognition.

The 2-tank intermittent aeration method is an anaerobic-aerobic activated sludge process of time-sharing type in which 2 complete mixing reaction tanks are connected in series, and aeration and agitation are periodically repeated in each tank. We have developed a new control system for the process which can secure anaerobic, anoxic and aerobic conditions through a combination of DO and ORP-Bending-point (corresponding to termination of denitrification) emergence time control. In the 1st tank, nitrification and phosphorus uptake occur in the aeration period, followed by denitrification and phosphorus release in the agitation. The 2nd tank performs nitrification and phosphorus uptake in the aeration and denitrification in the agitation. One cycle of aeration and agitation is approximately 2 hours. This control system was applied to the test plant (influent flow rate: 225 I/day) for two months under the conditions of HRT 16 hours and temperature 20 ±2 °C. We achieved stable and high removal ratios: TOC 94.9 %, T-N 89.4 %, and T-P 95.5 %. We also investigated the mechanisms of nitrogen and phosphorus removal and their material balance.

The use of water in agriculture should be monitored in order to be more efficient, with irrigation being the largest consumer of water in rural areas. Small farmers who are part of family farming have few resources to develop profitable activities and aiming their well-being, have created family irrigation kits which is a small drip irrigation system. The systems durability depends of some factors like clogging risk of drippers, which is often caused by the quality of the water used or the application of fertilizers to the irrigation water. This research aimed to analyze a family irrigation system with application of red potassium chloride, followed by a chemical agent to clear drippers (calcium hypochlorite) with water application before and after the fertilizer and chemical products (four treatments). At the after, the evaluations were analyzed with statistical quality control charts where the problem was detected in the final of application of the fertilizer, and the process capacity was analyzed showing that it was capable and also was analyzed the degree of system clogging in relation to the obstruction with the fertilizer and clearing with the chemical agent, which resulted in the recovery of the irrigation system (initial flow and distribution uniformity same the final) with recommendations for the use of fertilizers by drip irrigation like open the end lines after the fertigation and dissolve the fertilizer fully before application.

Agriculture is the primary source of livelihood for rural areas in Bihar. Agriculture being mostly dependent on monsoon is highly affected by scanty rainfall, weather variations, flood, etc. The study was conducted in Bhagalpur district of Bihar to assess role of different technologies in enhancing income and mitigate challenges faced by farmers. Three villages of Sabour block in Bhagalpur district namely Farka, Ghospur and English were selected for study. A total of 150 farmers (50 from each village) were selected randomly and data was collected using semi-structured interview schedule. Production innovations like high yielding varieties, new techniques, and home-made remedies of costly designs were identified, along with a marketing channel to sell vegetables from diara region. Some new crops like strawberry and fruits plantation in large area seemed to have good scope; poultry business also appeared to be promising. Some constraints were also identified which when rectified can give new potentials to agricultural production in this area.


with carrying out the decentralization reform public administration mechanisms play an important role in ensuring the comprehensive development of rural areas. Expanding the use of such mechanisms in the sphere of cooperation on the state level will facilitate development and support of small entrepreneurial forms, common use of material and technical basis, emerging new working places, building social infrastructure and engineering communications, providing qualitative services to citizens and preserving rural settlements. The objective of the article is to identify constituents of the comprehensive mechanism of public administration for development of service cooperation of rural areas in Ukraine and to integrate them into a coherent system which would facilitate realization of the state strategies and programmes to achieve the Sustainable Development Goals. The object of the research is a comprehensive mechanism of public administration for development of service cooperation. Research methodology is grounded upon the use of general scientific knowledge methods, in particular, logical and semantic, induction and deduction for formulating definitions, systemic and situational analysis for characterizing constituents of a comprehensive mechanism and identifying their interrelations. Based on the systemic approach it has been defined that comprehensive mechanism is an integrated system which combines interrelated and dependable functioning of legislative, institutional, organisational and economic, financial and credit, information and communication as well as staffing mechanisms in the sphere of developing cooperative movement in the rural localities. It is proved that every mechanism influences its particular direction and is formed at the international, national, regional and local levels based on cooperative values and generalized system of principles. Special attention is paid to the research of international and national legislation to generalize the system of principles of cooperation, intermunicipal cooperation, public authorities and public associations’ functioning, upon which the comprehensive mechanism for public administration of service cooperation development in rural areas of Ukraine is based.

The study aims to answer the question concerning how effectively cities of the Siklós district can involve the surrounding settlements in the tourism economy, thereby promoting the development of rural areas. In addition to local governments and tourism organizations, our important goal is to understand the ideas of service providers and their guests related to rural development, as well as the space use characteristics of the latter group. The key method is the questionnaire survey, the target group of which is the mayors of all settlements in the district, as well as the guests of the accommodations belonging to the different product types. The primary sources are based on two further series of interviews, which explore the opinions of service providers and professional organizations. Empirical experience shows that thematic trips can play a prominent role in the development of the less frequented small settlements. The essence of this is to connect the places offering traditional crafts and local products by a bike route.

Abstract   The demand for rural public transportation is dominated by people who cannot access private vehicles. In terms of the number of operating routes and the performance of their services, currently rural public transport services tend to decline. The mobility of rural communities to reach social facilities can be hampered if there is no public transportation service, which in turn will reduce the quality of human resources in rural areas. This study focuses on the movement characteristics of rural public transport passengers in Kuningan Regency. Several rural transportation routes were taken as samples, namely route 030 Cilimus-Linggarjati, route 061 Cilimus-Mandirancan, and route 037 Lengkong-Rancakeusik. This study shows that the characteristics of the movement of rural public transport passengers are an integral part in an effort to maintain rural public transport services. These characteristics of passenger movement can be used to improve the performance of public transportation, become input for public transport operators, and become material for local governments to make policies   Keywords: rural public transportation; public transport routes; public transport services; public transport performance.     Abstrak   Permintaan angkutan umum perdesaan didominasi oleh masyarakat yang tidak dapat mengakses kendaraan pribadi. Dari sisi jumlah trayek yang beroperasi dan kinerja layanannya, saat ini layanan angkutan umum perdesaan cenderung semakin menurun. Mobilitas masyarakat perdesaan untuk menjangkau fasilitas sosial dapat terhambat jika tidak ada layanan angkutan umum, yang pada akhirnya akan menurunkan kualitas sumber daya manusia di kawasan perdesaan. Studi ini berfokus pada karakteristik pergerakan penumpang angkutan umum perdesaan di Kabupaten Kuningan. Beberapa trayek angkutan perdesaan diambil sebagai sampel, yaitu trayek 030 Cilimus-Linggarjati, trayek 061 Cilimus-Mandirancan, dan trayek 037 Lengkong-Rancakeusik.

There are “urban-rural municipalities” in Polish administration nomenclature. They are territorial units where urban and rural areas have one name and one local government. There are also urban and rural municipalities that have one name but different local governments. That neighborhood of municipalities in Polish may be described as “municipalities bagel”. The aim of this article was to investigate whether and to what extent the “municipalities bagel” cooperate (coordinate) the exercising public tasks on the economic level. The article attempts to verify the research hypothesis: in “municipalities bagel” there is a lack of coordination of the exercising public tasks”. The research method was a diagnostic survey in which the questionnaire was conducted. In December 2019, questionnaire forms were sent to all “municipalities bagel” in Poland. The results of the research indicated a lack of coordination in the performance of public tasks between “municipalities bagel”. The result is a reduction of the efficiency of performance of public duties in such municipalities. The “municipalities bagel” are functionally related areas. This link is characterized by the subordination of the interests of the rural municipality (especially economic). The development of bagel rural communes is determined by the development and cooperation with their urban counterparts.
