‘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.

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.

This paper provides a detailed overview of the current situation of the coffee sector in the Rwandan economy and identifies the possible challenges that the sector is currently facing. The study has identified the economic and the livelihood indicators for farmers who are engaged in coffee production and also gives the Rwandan coffee sector’ situation and its position in the global coffee market. Also, the research has found out that in Rwanda, nearly 500,000 farmers produce coffee along with other crops, notably beans, savory banana and corn and found out that in 2012, coffee accounted for almost 30 percent of Rwanda’s total export revenue. On the other hand, the study revealed that the sector throughout all the coffee production process, has undergone different challenges especially climate change as it is reported by the Ministry of Agriculture and Animal resources. A low yield was reported in 2007 and climate variability was quoted among the causes. Insufficient rainfall in the last three months of 2006 (the period of coffee flowering) proceeding the short dry season in the first two months of 2007 was recorded. The reduced rainfall was also poorly distributed across coffee growing regions in Rwanda. In addition, the research revealed that even though the area under coffee production is increasing, the coffee production is decreasing due to unexpected climate change and variability in current years and also the improper use of chemical fertilizers by coffee farmers is very critical. The study concluded that adding value to the coffee supply chain of Rwanda is adding direct economic benefits and important indirect social benefits to the lives of individuals and to the health of communities in Rwanda. Moreover, more effort should continue to raise the profile of the Rwandan coffee sector suggesting that proper use of chemical fertilizers, solid marketing channels and climate change adaptations measures would be the fair ways of making the sector more profitable and considering national targets to increase coffee export revenues, a few simple measures to improve the performance of the sector could have substantial effects on the country’s economic growth.

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.

This article describes genesis and the advances of schooling, research and extension of animal nutrition science and practices in Bangladesh. It portrays sine qua non of the advancement of animal nutrition, fodder production and frontier knowledge of allied disciplines. Domestic growth of good practices and its global and regional competitive advantages are delineated for supporting the growing need of safe animal sourced food pillared with profit, people, planet and the ethics of sustainable production of farm animals. A vision of becoming world middle income country with a national population plateau of around 202.0 million and demographic shifts by 2050 may require the annual production of 130.0 and 27.0 thousand tons of manufactured dairy and beef feed furthering global trading competitions for feed ingredients. This competition may be minimized through the production and supply of domestic sourced unique quality feeds and value additions to roughages. Capacity enhancement in research, education and extension will boost socioeconomic and the production efficiency of farm animals and enhance sustainable growth of feed industry racing with regional and global competitions.

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.

In developing countries, consumption habits have changed with the increase in population, the development of technology and industrialization. For this reason, good management of the increase in the amount of solid waste by municipalities is very important for the health and sustainability of nature. The location of the facility to be established is important for the regular storage and efficient disposal of solid wastes. Site selection of landfill facilities in the ‘Site Management and Operation Guide for Landfill Facilities’ published by the General Directorate of Environmental Management; The ratio of the volume to the area, the distance to the buildings, the wind direction, the external view (landscape), the effect on the traffic on the side, the profit from the finished facility, and the effect on the water are evaluated under the sub-headings. With the ‘Konya Solid Waste Management Project’, ‘Aslım Sanitary Landfill’, which was used until 2017, was closed. Instead, the ‘Konya Solid Waste Landfill Site’, which was established in a different region to meet the need, was put into operation. In the study to be carried out in this context; Both fields were evaluated according to the specified criteria and compared with each other using the Analytical Hierarchy Method. As a result, it is aimed that the success rate of the location selection of the new solid waste storage area will be revealed and it will be a base for similar studies to be done in the future.

Bu çalışmada, İç Anadolu bölgesinde yılın büyük bölümünde kuruyan tuzlu bataklıklarda doğal olarak yetişen bazı otsu halofitlerin peyzaj tasarımında kullanılabilirlikleri araştırılmıştır. Araştırma kapsamında 2016 ve 2017 yıllarında Konya, Ankara, Aksaray ve Nevşehir civarında bulunan tuzlu habitatlarda vejetasyon döneminde periyodik olarak alan çalışmaları yapılmış ve halofit bitki türlerine ait fotoğraflar ve herbaryum örnekleri alınmıştır. Seçilen türlerin genel botanik ve ekolojik özellikleri verilmiş, estetik ve fonksiyonel özellikleri dikkate alınarak peyzaj tasarımında kullanım değerleri belirlenmiştir. Araştırma alanında bulunan tuzlu habitatlarda vejetasyon dönemlerinde yapılan saha çalışmaları sonucunda peyzaj tasarımında kullanılabilecek 19 familya ve 38 cinse ait 59 halofit bitki türü tespit edilmiştir. Bu türlerden 25 tanesi Türkiye için endemik olup endemizm oranı %42’dir. 11 tür ile Asteraceae en fazla temsil edilen familya olurken, ardından 9 tür ile Plumbaginaceae ve 8 tür ile Chenopodiaceae familyası izlemiştir. Plumbaginaceae familyasından Limonium cinsi, 8 tür ile peyzaj tasarımında en fazla kullanım potansiyeli olan cins olmuştur. Peyzaj tasarımında en yaygın kullanım alanları, 49 türle çatı bahçelerinde belirlenirken, 31 türle yer koruma ve erozyon önleyiciler izlenmektedir. Çoğu sukkulent olan bu halofit türler hem sulak hem de kurak alanlara iyi adapte olduklarından gelecekte yaşanabilecek küresel ısınma tehdidine karşı kurak ve çorak araziler için sürdürülebilir bir alternatif olacaktır. Bunun yanında çoğu endemik olan bu türlerin peyzaj tasarımında kullanılması aşırı tuzdan çoraklaşmış arazilerin restorasyonu, biyolojik çeşitliliğin korunması ve sürdürülebilir tarım uygulamaları için büyük önem taşımaktadır.

This study aims to determine the functionality and benefits of blockchain technology in food procurement. Within the scope of the study, Migros Trade Inc., a retail food supply company implementing blockchain technology in Türkiye, was examined as a case study. The study employed a qualitative research case study design, asking expert participants from Istanbul and Izmir to give their opinions on pre-designed themes, and conducting descriptive analyses of the data collected. The themes of the research are food supply chain, good agricultural practices, sustainability in food, blockchain applications in food supply and food safety. At the end of the study, it was found that the transparency and traceability principles of blockchain have a positive impact on consumers and supply chain stakeholders. However, challenges such as technical infrastructure and performance, as well as the reasons for not starting the process directly from the field, were the problems experienced. The data shows that blockchain technology is an efficient system that should be expanded in the food supply chain.

Healthy life in a sustainable environment is possible with accessible food production. The Covid-19 epidemic is a serious threat worldwide. This epidemic has revealed the importance of agricultural products. One of the most important areas of the epidemic affecting the whole world is exports; however, increased demand for agricultural products and exports in the epidemic process in Turkey. Turkey has a say in the trade of seedless dried grapes in the world. Seedless dried grape is on the healthy products list of the WHO. In 2019/2020, it had a share of 36% of world exports (with 246 thousand tons of export). This study was performed to evaluate their thoughts and farmers’ problems with the adoption of organic farming in Besni district of Adıyaman. The research conducted in-depth interviews with the farmers producing organic grapes. Also, a face-to-face survey was conducted with 50 farmers. According to the findings, the land width of the farmers is not much. It has an average growing area of 37.52 decares. An average yield of 1.808 kg da-1 is obtained from this area. Serious differences have been found between conventional and organic farming. Moreover, government supports, high product prices, income, health, sustainability, and environmental protection are reasons farmers switch to organic farming.  However, farmers argue that organic farming is less costly than conventional farming. Access to chemicals and marketing are major problems. As a result, farmers should be informed about organic farming. Additionally, it is thought that these studies will increase the productivity and product quality of the farmers. It is predicted that it will prevent rural to urban migration in the region.
