Rivers are the lifeline of Bangladesh economy and serve as the source of water supply, fisheries, irrigation for agriculture, low-cost transport, generate electricity and conserve biodiversity. The Ichamati River situated in Pabna, Bangladesh is also a blessing for the city. However, recently, due to the irregular and unplanned activities adjacent to the riverside, the life, flow and water quality of the river is in a vulnerable condition. This study aims to identify the present status of the Ichamati River and provide an effective design approach and policy measures in restoring the river flow and control water pollution. The data was collected from the questioner surveys, key informant interviews and focus group discussions. Results suggest that several factors such as the construction of an illegal settlement, unplanned waste dumping, disposal of fiscal sludge through sewerage connection, lack of awareness among people regarding the importance of river biodiversity and absence of riverfront development and conservation plan are responsible for water pollution, inconsistent water flow and damaging the life cycle of Ichamati river. The design approach and policy measures were developed based on the perceptions of local community people, experts and government officials. The suggested policy measures will help to restore the flow of the river and reduce the water pollution, and the design approach will ensure the economic benefit of the riverfront development in future.

In order to reduce the demand for the forest based raw materials by the organised industrial sectors like the large integrated pulp and paper mills, the Government of India started promoting several small-scale pulp and paper mills based on non-wood agricultural residue raw materials. However promotion of these small mills has created another environmental problem i.e. severe water pollution due to non-recovery of chemicals. Because of the typical characteristics like high silica content etc. of the black liquor produced and the subsequent high capital investment needed for a recovery system, it is not economically feasible for the small Indian mills to recover the chemicals. While the quantity of wastewater generated per tonne of paper produced by a small mill is same as from a large integrated pulp and paper mill with a chemical recovery system, their BOD load is four times higher, due to non recovery of chemicals. However the existing wastewater disposal standards are uniform for large and small mills for e.g. 30 mg BOD/l. To meet these standards, the small mills have to install a capital intensive wastewater treatment plant with heavy recurring operating costs. Therefore the feasible alternative is to implement various pollution abatement measures, with the objective of not only reducing the fibre/chemical loss but also to reduce the investment and operating costs of the final wastewater treatment system. To illustrate this approach, a case study on water pollution abatement and control in a 10 TPD mill, will be discussed.

Abstract Background The demographic situation in the Split-Dalmatia County (SDC) is characterized by negative trends in the new millennium. Such a demographic picture entails many societal challenges. Considering the far-reaching consequences of population decline, the goal is to show what maternity data have been like in the SDC in the last decade. Methods Individual birth reports from health institutions in the SDC were used in the presentation of the maternity data. Demographic indicators were calculated based on data from the Croatian Bureau of Statistics. Results In 2018, in the SDC were reported 4,438 deliveries (13% less vs 2009; 5,103 deliveries) with a total of 4,577 children delivered, whereof 4,561 were live births and 16 were stillbirths. From a total of 4,516 live births, 13 live-born neonates died during the first week of their life. Most of women in labor (89%) were residents of the SDC. The average age of the new mothers was 28.9 years (in 2009; 26.9 years). Childbirth was most frequently recorded in the maternal age group 30 -34 (1,556 deliveries, i.e. 110,9/1,000 women of said age group; 92/1,000 in 2009). Among childbearing women with known data on earlier deliveries (4,431), 2,029 or 45.8% had their first deliveries, 1,549 or 35% had their second deliveries, 808 or 18% had their third or higher birth order deliveries. According to an estimate in 2018, 448,071 people lived in the SDC, less 1.5% from the last census (2011). The live birth rate was 9.5 /1,000 in 2018 (2009; 10.9/1,000). The total fertility rate was 1.53 in 2018 (2009; 1.6). The natural increase rate in 2018 was negative at -1.8 (-830 persons) (2009; 0.5 (250 persons)). Conclusions Depopulation, low birth rates and fertility, are the demographic reality of Split-Dalmatia County as well as Croatia, which requires adoption and implementation of various public policy measures that positively affect fertility to improve the demographic picture. Key messages Depopulation, low birth rates and fertility, are the demographic reality of Split-Dalmatia County as well as Croatia. Adoption and implementation of various public policy measures that positively affect fertility to improve the demographic picture are needed.

The paper first presents evidence from the engineering literature on air and water pollution control, which shows that, when the pollution abatement technologies are in place, large reductions in pollution have been achieved at costs that are small relative to the costs of production. A simulation model is then developed to study the effects of technical progress on pollution abatement, and applied to particular cases in developing countries. The results are compared with the projections of an environmental Kuznets curve: they reproduce the latter if policies were not to be introduced until per capita incomes reached levels comparable to those of the industrial countries when they first introduced their policies; but show dramatically lower and earlier peaks if policies were to be introduced earlier. The conclusion is shown to apply more generally, and it is argued that developing countries can aspire to addressing their environmental problems at a much earlier phase of development than the industrial countries before them.

Abstract This article presents the main elements of the creation of the pro-innovation policy as a new public policy. For understanding this kind of policy we should analyse the structural and functional aspects this public policy. The main concept of structural description pro-innovation policy is a National Innovation System. NIS is being analysed as a sub-functional part of the political system as a whole. This sub-functional political system should also have social and institutional connections. Furthermore, pro-innovation activity is connected with the market, state, and social aspects. The pro-innovation policy and system must be based on social endogenous resources, needs, and possibilities. These are the basic factors for legitimisation and participation, which are crucial elements for the effective implementation of the pro-innovation policy.

Marine ecosystems are affected by water pollution originating from coastal catchments. The delivery of water pollutants can be reduced through water pollution abatement as well as water pollution treatment. Hence, sustainable economic development of coastal regions requires balancing of the marginal costs from water pollution abatement and/or treatment and the associated marginal benefits from marine resource appreciation. Water pollution delivery reduction costs are, however, not equal across abatement and treatment options. In this paper, an optimal control approach is developed and applied to explore welfare maximizing rates of water pollution abatement and/or treatment for efficient diffuse source water pollution management in terrestrial-marine systems. For the case of diffuse source dissolved inorganic nitrogen water pollution in the Tully-Murray region, Queensland, Australia, (agricultural) water pollution abatement cost, (wetland) water pollution treatment cost and marine benefit functions are determined to explore welfare maximizing rates of water pollution abatement and/or treatment. Considering partial (wetland) treatment costs and positive water quality improvement benefits, results show that welfare gains can be obtained, primarily, through diffuse source water pollution abatement (improved agricultural management practices) and, to a minor extent, through diffuse source water pollution treatment (wetland restoration).
