Djouhri Nesrine | Bouammar Boualem | Dadamoussa Mohamed Lakhdar
The objective of this study is to diagnose the potato sector in the El Oued region by highlighting the technical and environmental situation of this sector. For this purpose, a field survey was carried out at the level of 75 farms in the El Oued region. The Oued Souf region’s Farm Sustainability Indicator (IDEA) is important. The assessment of agro-ecological, socio-territorial and economic indicators indicates that the agro-ecological indicator is the most represented by (the indicator of fertilizer and agricultural practices) by 98 out of 100. The results of this study show that this crop presents a good adaptation to the conditions of the region. This sector is undergoing significant development and is of great importance because this agricultural activity represents an economic potential at the local, regional and national levels. However, this sector remains fragile in relation to various constraints of a technical nature (unreasonable irrigation and fertilization and high seed prices), economic (price fluctuations and disorganized markets) and environmental (diseases, weeds) which directly influence the functioning of farms and therefore their profitability. This is why it is necessary to face the problems encountered and fight against the factors that can hinder the sustainability of this sector and give a competitive value.

2021
Santosh Kumar Bhattarai | Suman Bhattarai | Chandan KC | Arun GC
‘Circular economy’ in agriculture centres on the production of agricultural commodities using a minimal amount of external inputs, closing nutrient loops and reducing negative discharges to the environment (in the form of wastes and emissions). This can be achieved through the (re)design of maintenance, repair, reuse, remanufacturing, refurbishing, and recycling. Under the principles of CE, products and materials approaching their end-of-life stage can be regenerated or restored or replaced. Circular agriculture is aimed at closing the loop of materials and substances, and reducing both resource use and discharges into the environment. New measures like environmental taxes, insurance for liability resulting from environmental damage, cap and trade system and environmental labelling can be explored to promote transition of a current linear model to a circular one. The circular economy in Nepal is in infant stage and there is plenty of works to be done in this sector. The results of the paper will be instrumental for the transition of Nepalese agricultural sector to a more circular one.

In this epoch, the tremendous increase in the world population accounts for the continuous supply of foodstuff. According to the FAO report, the global population is probable to cross the 9 billion in 2050. With constant population pressure, we are going to face the challenges of food shortage globally about agriculture. The animal production field provides a major share in the supply of foodstuff to compensate for the stress of food scarcity. By adopting the advanced technologies in the animal production field, its productivity can enhance significantly. Innovation in technology has made work easier with the development of different software and the internet. Technologic development made farmers work more contentedly hence, ultimately amplifying the animal production, proficiency, profitability as well as providing a prompt way for livestock sustainability. The animal production consists mainly of 8 factors including 3 major (animal breeding and genetics, animal nutrition, and reproductive performances) and 5 minor (health observation, farm management, water, manure, machinery, environment control, milking automation and electronic identification). The use of advanced technologies in these sectors is found to be fluent by intensifying the ratio of sustainable livestock farming and the welfare of mankind in terms of food security. In this review, innovative tactics and techniques for animal production are potted with positive research results and their drawbacks as well. The use of innovative technologies in their respective fields is close to taking control of whole world manufacturing under its hand to accomplish the world prerequisite regarding food scarcity.

2018
Cevher Özden
Competition is fierce in the world markets of agricultural products. It is especially harder for developing countries to compete with the wealthier industrialized countries. Canada entered in the lentil production mainly for export purposes in the early 1990s and exports nearly all of its lentil products every year. As Canada has become the dominant power in lentil trade, Turkey’s lentil production has declined notably. In the study, Turkey’s adaptation to this trend is investigated. Based on the results, it is concluded that Turkey’s market share has not changed in its traditional markets and its export has risen both in quantity and value. For instance, Turkey’s lentil export has increased from 127 Thousand tons in 1997 to 178 Thousand in 2013. This is achieved through partnerships between Canadian and Turkish entrepreneurs. Furthermore, lentil producers in Turkey have shifted to alternative crops, which yields higher income.

2017
Ertuğrul Karaş | İrfan Oğuz
Land use management requires controlling natural resources for sustainability. Soil erosion related to improper land use is a major issue around the world. Land degradation may harm the health of ecosystems. Defining the soil loss in a basin is the starting point in the restoration of soil quality for crop production. Reducing soil losses to a tolerable rate is one of the primary objectives for sustainability and soil conservation. Central Anatolia is under considerable risk due to an increase in the cultivation of marginal lands for food production. Cultivated lands have already been reached the final limits throughout the last 50 years. Moreover, forests and considerable areas of pasture have recently been converted to ploughed fields due to agricultural expansion. This study was conducted in the Sarısu basin to evaluate soil losses and land use management for sustainability. The Universal Soil Loss Equation model and Geographic Information System techniques were used to estimate the soil losses. The mean potential soil loss of the basin was calculated to be 1.88 t ha-1 per year with the Universal Soil Loss Equation model. These results are comparatively small when compared to the average value for Turkey of 13 t ha-1 yearly. Our calculated results are closer to the value for the Sakarya river basin, which is approximately 2.77 t ha-1 y-1. In this study, land usages in the Sarısu basin were evaluated in terms of soil losses, tolerable soil loss rates and soil conservation precautions.

Elif Duyuşen Kokulu | Eylül Ceren Özyürek
Current study intends to find out the carbon footprint of Dokuz Eylül University's Tınaztepe Campus and comprehensively assess its environmental impact in the process. The study provides a detailed analysis of carbon emissions resulting from the campus’s energy consumption, transportation, water usage, and other sources. Based on these analyses, the total CO2 emmission of the campus has been determined, taking into account the carbon sequestration capacity of the university's forested area. Calculations performed using the IPCC Tier 1 Model estimate that Tınaztepe Campus's total annual carbon footprint is 2,458.44 tons of CO2. Additionally, the annual carbon footprint per capita has been calculated as 0.059 tons of carbon footprint. According to the findings, the largest portion of carbon emissions is from natural gas consumption, while the smallest is from water consumption. In light of this data, various strategic recommendations have been developed to reduce the campus’s carbon footprint. These recommendations include measures such as increasing energy efficiency, adopting more sustainable transportation methods, and reducing water consumption. The results of this study provide valuable insights for universities to consider when developing sustainability policies.

2023
Zekeriya Can Erbil | Büşra Altay
Today’s cities show an unplanned and rapid development in direct proportion to the development of technology. As a result of rapid and unplanned development, the natural silhouette of the cities has deteriorated and the proportion of reinforced concrete structures has increased day by day. For these reasons, putting green areas in the second plan causes some ecological problems for the city. The existence and sustainability of green areas are among the most important approaches that can reduce these problems. If we look at the concept of sustainability and its derivatives, the university campuses in the city give the appearance of a small city model and the green campus, sustainable campus, eco-campus, etc. that have emerged in recent years. Due to these concepts, in this study, “Selçuk University Alaeddin Keykubat Campus”, located within the provincial borders of Konya, was chosen as the study area. The aim of the study was to determine the shadow lengths created by the buildings in the “Selçuk University Alaeddin Keykubat Campus” on the green areas and the new building or open green areas, and according to the light, shade and water requirements of the plants in the open green areas in line with the obtained data. Its contribution to ecological sustainability and green campus studies has been evaluated by revealing whether it is placed in areas with 2D (2D)-3D (3D) software and with different analysis techniques. In the light of the data obtained; It is seen that the shadow periods created by the buildings in Selcuk University Alaeddin Keykubat Campus are higher in December and February, and the shadow durations are less in other months. The shadow periods of the building’s immediate surroundings are longer than the open areas. It has been determined that the species in the vicinity of the building are adversely affected by this situation. Plants are exposed to the sun, especially in the summer months, so the water demand and consumption of plants increases.
