Abstract:
The development of ecological economics is a major strategy for development in the 21st century. Although scholars have been rising more and more interesting for ecological economic over the past 10 years, it is still unclear what is the change will be facing in the future. In order to provide a theoretical basis for the future development of ecological economy, our article analyzes the current research progress of ecological economy on the basis of a bibliometric analysis. The results show that (1) sustainable development of an ecological economy is a hot research topic; (2) there is little cooperation and exchange between institutions and among scholars regarding ecological economics; (3) the number of publications on ecological economics is increasing, with a relatively large number being published in China. Therefore, we must strengthen the cooperation between institutions and among scholars and improve the research content, vision, and methods in this field. This study provides a theoretical basis for the future development of ecological economy.

Abstract:
In this study, an analysis of organic fertilizer of an agro-waste (Sesame straw) plus cow dung was carried out using an epigeic earthworm species Eisenia fetida and Perionyx sansibaricus. Sesame straw is abundantly produced after each harvesting of the crop in Kharif season in arid region of tropical India. The compost produced in presence and absence of earthworm exhibit significant (P0.05) changes in physicochemical properties respectively. In control bedding, the values of water holding capacity enhanced significantly (P<0.05) by 1.28 fold, while organic carbon and C/N ratio decreased significantly (P<0.05) by 19.93% and 31.25% respectively after 60 days of composting.Working of E. fetida in the bedding material showed significant (P<0.001) difference in the level of pH, electrical conductivity, water holding capacity, organic carbon, total nitrogen, C/N ratio, available phosphorous and available potassium. After 60 days of working of P. sansibaricus, these physicochemical properties of the bedding substrate also changed significantly (P<0.001). Analysis of vermibed showed a gradual increase in electrical conductivity, water holding capacity, total nitrogen, available phosphorus and available potassium by 1.51, 1.86, 1.95, 1.78 and 1.75 fold respectively. While the values of pH, organic carbon and C/N ratio declined by 9.30%, 41.80% and 71.48% respectively within 60 days of decomposition. Thus, E. fetida and P. sansibaricus can be applied for production of organic fertilizer of sesame chaff plus cow dung to fulfill the requirement of bio-fertilizers for organic farming and agro-waste management in arid environment.

Abstract:
The water network plays an important role in maintaining the stability of regional water resource and ecological environment. It is also affecting the harmonious development between environment and economy. Guangxi is one of the provinces with relatively rich water resources in China, while the ecological water network exists deficiencies and faces challenges. The current situation and defects of ecological water network in Guangxi province will be discussed. By studying the experience of the establishing and the preserve of ecological water network in various regions at home and abroad, some suggestions and targeted measures will be mentioned for a better ecological water network in Guangxi.

Abstract:
Agricultural systems result of the coevolution between social and natural systems, where biodiversity and natural resources play an important role, emerging interactions between crops and the natural environment that allow the development of ecological processes which interact with external inputs. This research aims to describe the agricultural practices developed by the Guarani Indigenous People in the agricultural systems located within the biodiversity corridor of the Upper Paraná Atlantic Forest. This exploratory study is focused on multiple cases, with a qualitative approach and data were collected during 2017 and 2018 in eleven indigenous communities. The main practices developed for the management of biodiversity are polyculture, rotation, and embroideries; they also practice agroforestry and livestock-raising. The main difficulty they face is the reduction of the surrounding biodiversity, which affects the sustainability of the system. This study shows ways for nature-based solutions and ecosystem-based adaptation according to current needs for greening the economy.

Abstract:
This work aims at studying different green spaces’ experiences in developed countries and extrapolates the experiences to Oromia cities in Ethiopia; in order to investigate and promote greenery infrastructure in selected cities. To do that greenery practice performance data were collected in four cities, which were classified into two groups as good and weak performers. As a result, Adama and Bishoftu cities were good urban greenery performers whereas Burayu and Sebeta were weak performers. The cities were also selected non-randomly to investigate the current urban greenery practice and different green areas in each city. Eight green areas were taken as samples for observation, where qualitative and quantitative data were collected from primary and secondary sources. The assessment of data confirmed that green areas along the roadside, recreational parks, open areas, and nursery sites existed in most cities. The urban plan of some cities does exclude most green area components. Greenery sites in Bishoftu and Adama are relatively better, while in Burayu and Sebeta urban greenery are highly abused for changing to another type of land use, e.g., residential and institutional areas. The technical skills of tree planting, care, protection, and management were also observed as a collective resource.

Abstract:
The effects of different nitrogen application levels on rice yield and greenhouse gas (NO2, CH4) emissions from rice fields under the combined action of straw and milk vetch. Two treatments were set up in the main area of this experiment: R0 (no straw returned to the field, 0); R1 (amount of straw returned to the field under normal conditions, 6000kg·hm-2). Before turning the straw back into the field, use a circular knife to cut the straw into 10~13cm.And 3 kinds of nitrogen application treatments in the sub-district: N1 (no nitrogen application, 0), N2 (nitrogen application, 15 kg·hm-2), N3 (nitrogen application, 30kg·hm-2), two-factor cross-combination,and a non-nitrogen control CK, total of 7 treatments. The results showed that in 2017, early rice R1N2 treatment increased the most obvious yield, which was 32.44% higher than CK, and late rice R1N1 treatment increased the most significantly, which was 17.91% higher than CK. CH4 emissions is positively correlated with the amount of straw returned to the field, while the amount of N2O is the opposite.The N2O emission flux was highest in the treatment of R1N3, and the CH4 emission flux was the highest in the treatment of R1N2.

Abstract:
Pigments play an essential role in imparting colors to the various organs of invertebrates particularly, insects. Genetic evolution and adaptive pigmentation of invertebrates have been studied which depicted that insect colors respond to the climatic changes. The physical, chemical and structural properties of insect pigments are being studied by researchers for years to elucidate their evolutionary aspects of physiology, metabolism, and economic importance for human welfare. Color development in insects varies within the species of different genera. In this state-of-the-art literature review, we discuss the variety of pigments other than visual ones found in different species of insects. The review also highlights the potential benefits or functions of pigments to insects.

Abstract:
The effects of chemical agent (Sodium Azide) on Onion growing in organic and inorganic fertile soil was to be examined during this study. The analysis work was carried out within the green house of the research laboratory technology of the Oke Ogun Science Laboratory Technology, Saki, Oyo State. Onion seeds were soaked inside different beakers containing the mixture of Sodium Azide and water mixed with 10 ml of Phosphate solution for 4 hours. Also, the control was soaked with normal water and 10 ml of Phosphate buffer solution. The treated seeds of onions was planted in plastic containers containing 4.2 g of weighed humus soil within the green house at the Department of research lab Technology of The Oke Ogun polytechnic school, Saki Oyo State. The samples parameter were taken daily for six consecutive months. The result obtained was additionally subjected to statistical analysis by using DMRT techniques. The results showed that the stem length was ranged from 11.39±0.62 and 9.98±0.52 with sample of onion without sodium Azide and inorganic had the highest stem length values and samples of onion with Sodium Azide and inorganic had very cheap stem length. However, the leave length ranged from 29.63±0.12 and 22.45±0.10 with the Onion samples with inorganic and Organic fertilizers which had the highest leave length and sample of onion without Sodium Azide was very low leave length. The results of this study showed that each one the parameters studied within the plant were low with Sodium Azide treatment. The decrease in plant growth, plant heights, root lengths, and Phaonerogam survival, fruit yield per plant and height at maturity with agent concentration. It is hereof suggested that Sodium Azide (NaN3) was expected to produce mutation in onion that area unit extremely liable to harmful pathogens and making them cheap to be useful for farmers.
