Fujian province is one of the coastal provinces with rapid economic growth after the reform and opening to the outside world. Being one of the two basic strategies of China in the new era, sustainable development plays a directive role in the coordinated development of socio-economy, natural resources and ecology of Fujian. This paper analyses some important issues influencing sustainable development in Fujian in the next 20 years, such as the sustainable development of economy, investment environment improving and further opening to the outside, urbanization and coordinated development of city system, rational exploitation of natural resources, environmental conservation and ecological rehabilitation, and narrowing intraprovincial gap. Corresponding countermeasures are put forward. 展开更多

Developing the Changjiang(Yangtze) River and building a developed economic zone along the bank area of the Chanajiang River is a great strategic decision of the national macroeconomic development distribution. This decision has both given an impetus to fast development of the regional economy and exacerbated the contradiction among economy and resources and environment. In this paper, some major problems ekisting in economic sustainable development, such as scattered industrial structure, duplicated construction of the great projects, enlarging the development gap of the regional economy and deteriorated environment etc., have been studied. The results show that scattered structure and duplicated distribution of some key industries and projects, especially automobile, electronics and petrochemical industry and communication, power installations, is one of the reasons for low industrial economic benefit; the great development gap among upper, middle and lower reaches areas are enlarging since the 1990’ s; soil erosion, nood disaster and environmental pollution are still exacerliating due to unreasonable over-development. Based on the above analysis, this paper brings out some countermeasures and proposals for increasing the ability of regional sustainable development, including transregional reorganization of industrial structure linking by assets and speeding the process of regional economy integration; gradually controlling and reducing the development gap arnong upper, middle and lower reaches areas through regional cooperation on a mutually beneficial basis; as well as strengthening ecological construction and environmental protection and increasing environmental bearing capacity etc. 展开更多

Globally, about one third of all food produced is wasted every year. Losses take place along the entire food chain and they need to be analyzed and monitored due to their impact on the development of the food sector. In addition to quantitative losses, irrational use of food contributes to the depletion of natural resources (water and energy) and poses a threat to the environment, constituting a barrier to sustainable development of the food sector. The aim of this study was to establish the causes and effects of food waste throughout the food supply chain and to propose mitigation measures. Identified causes of food waste can be divided into two groups. The first are those that lead to the fact that food cannot be consumed (e.g., inadequate conditions of agricultural production and interruption of the cold chain). In the second, those that cause food cannot be sold (e.g., wrong label and wrong product weight). Most of the identified causes of food waste can be avoided (e.g., by improving the conditions of production, storage, and transportation). However, it is not possible to eliminate all potential errors leading to food waste. It is therefore necessary to consider what action to take to use food as intended. One way to reduce losses and food waste can be re-distributing to charity. 展开更多

The evolution of the lakes during Holocene can be divided into three periods. Since Ming Dynasty, owing to natural factors and human activity, the lakes have accelerated the shrinking process. This has resulted in a series of rural and urban environmental problems, such as the disasters of flooding, inundation, and water\|logging; declination of aquatic resources; increase of diseases; swamping of lake districts; and deterioration of urban environment (taking Wuhan City into consideration). In order to realize sustainable development in this area, several corresponding countermeasures should be taken. 展开更多

Mathematics is a key factor in achieving the Sustainable Development Goals (SDGs), because of its applicability to real situations. To achieve the set goals in SDG, this paper suggests some mathematical methods that will be useful for solving real situations in relation to goals 2 and 12 of SDGs approved by UN when modeled mathematically. The Northwest Corner Method (NWCM), Least Cost Method (LCM), and Vogel Approximation Method (VAM), which are the initial solution methods were examined to ascertain the ideal route of transporting commodities from production facilities to requirement destination while the optimal solution methods involve Stepping Stone Method (SSM), and Modified Distribution Method (MDM), that give the feasible solution which will enhance minimum transportation cost were also thoroughly defined. Subsequent research shall focus on application of the methods in relation to SDGs problems in comparison with other existing methods. 展开更多

The mathematical and statistical modeling of the problem of poverty is a major challenge given Burundi’s economic development. Innovative economic optimization systems are widely needed to face the problem of the dynamic of the poverty in Burundi. The Burundian economy shows an inflation rate of -1.5% in 2018 for the Gross Domestic Product growth real rate of 2.8% in 2016. In this research, the aim is to find a model that contributes to solving the problem of poverty in Burundi. The results of this research fill the knowledge gap in the modeling and optimization of the Burundian economic system. The aim of this model is to solve an optimization problem combining the variables of production, consumption, budget, human resources and available raw materials. Scientific modeling and optimal solving of the poverty problem show the tools for measuring poverty rate and determining various countries’ poverty levels when considering advanced knowledge. In addition, investigating the aspects of poverty will properly orient development aid to developing countries and thus, achieve their objectives of growth and the fight against poverty. This paper provides a new and innovative framework for global scientific research regarding the multiple facets of this problem. An estimate of the poverty rate allows good progress with the theory and optimization methods in measuring the poverty rate and achieving sustainable development goals. By comparing the annual food production and the required annual consumption, there is an imbalance between different types of food. Proteins, minerals and vitamins produced in Burundi are sufficient when considering their consumption as required by the entire Burundian population. This positive contribution for the latter comes from the fact that some cows, goats, fishes, ···, slaughtered in Burundi come from neighboring countries. Real production remains in deficit. The lipids, acids, calcium, fibers and carbohydrates produced in Burundi are insufficient for consumption. This negative contribution proves a Burundian food deficit. It is a decision-making indicator for the design and updating of agricultural policy and implementation programs as well as projects. Investment and economic growth are only possible when food security is mastered. The capital allocated to food investment must be revised upwards. Demographic control is also a relevant indicator to push forward Burundi among the emerging countries in 2040. Meanwhile, better understanding of the determinants of poverty by taking cultural and organizational aspects into account guides managers for poverty reduction projects and programs. 展开更多

China's economy in 2005 chalked up another year of 9.9 percent surging growth. In 2005 the government's attention was focused on the many negative consequences of China's past unbridled economic growth, from rural poverty to environmental degradation and wide income disparities, calling for more "sustainable growth" or "balanced development ". The new development paradigm fit nicely into President Hu Jintao's concept of "scientific development" and was embraced by the 11th Five-Year Program (2006- 2010). The year 2006 might go down in China's economic history as an important turning point, as the Hu-Wen leadership will start new development strategies to fix problems previously associated with strong economic growth. Strictly speaking, many of China's "growth problems " from regional disparities to environmental degradation, are actually quite inevitable - as a part of the development process. But their gravity has often been aggravated by poor governance, blatantly pro-growth policies, and local corruption. Overall, the Chinese leadership has come to realize that its past development patterns are physically unsustainable, and politically and socially unacceptable. It has embraced the need to change. But all development changes will take a long time to yield concrete results. 展开更多

The Yellow River Delta (YRD) is one of the biggest deltas that have not been developed in the world. During the turn of the centuries, YRD development is listed in the two major projects in the new century by Shandong provincial government. According to the plan, YRD will become an important energy, chemical and agricultural production base in 15-20 years. In view of its location and natural conditions, so far there exist a lot of environmental problems in YRD. Thus the principle of economic development coordinating with environmental protection must be implemented during YRD development. Forestation is one of the vital measures to cope with environment degradation. Therefore, strategies of forestry development and techniques of tree planting in different land use types are discussed in the paper based on site classification with specific problems involved . 展开更多

The Sendai Framework for Disaster Risk Reduction 2015−2030’s(SFDRR)framing moved away from disaster risk as a natural phenomenon to the examination of the inequality and injustice at the root of human vulnerability to hazards and disasters.Yet,its achievements have not seriously challenged the long-established capitalist systems of oppression that hinder the development leading to disaster risk creation.This article is an exploratory mapping exercise of and a collective reflection on Sustainable Development Goals(SDGs)and SFDRR indicators-and their use in measuring progress towards disaster risk reduction(DRR).We highlight that despite the rhetoric of vulnerability,the measurement of progress towards DRR remains event/hazard-centric.We argue that the measurement of disaster risk could be greatly enhanced by the integration of development data in future iterations of global DRR frameworks for action. 展开更多
