Converting vacant lands for urban agriculture has become a popular topic for American cities to engage in on a program and policy level. The advocates of urban agriculture cite a number of potential benefits, ranging from promoting sustainable urban development, fostering social interaction and educational opportunities, regenerating neighborhoods, and empowering residents. With the emergence of vacant lands in South Korea, different strategies have been implemented for productive use. Nonetheless, less attention has been paid to reinvent vacant lands for urban agriculture. Therefore, this study has examined the case of the City of Milwaukee's vacant land initiatives and programs that were known to have brought a series of positive neighborhood revitalization outcomes. Compared to the case of Milwaukee, intensive land use and high property prices have turned to be the major actors that prevent an active use of vacant land for urban agriculture within the context of South Korean cities. Thus, this paper proposes the possibility of using vacant lands in apartment complexes for urban agriculture.

BACKGROUND: Development of water recycle technologies is important for human health and sustainable agriculture. However, few studies have been conducted to examine the purification methods or the water quality of reclaimed wastewater in Korea. METHODS AND RESULTS: In this study, the different wastewaters including reclaimed wastewater and waste nutrient solution (NS) were evaluated. The changes of water quality in reclaimed wastewater and NS were determined using ultraviolet (UV) treatment and sand filtration with charcoal. Our results showed that one of the most critical limitations of reusing wastewater was the presence of harmful pathogens that possibly cause human health risks. CONCLUSION(s): This study suggests that the application of UV treatment or combined with sand filtration on reclaimed wastewater and waste NS effectively removes the total coliform bacteria below the harmful or acceptable level. For future studies, a long-term field monitoring after applying reclaimed wastewater or NS is needed.

우리나라 식생활교육은 2009년 식생활교육지원법이 제정되면서 건강, 환경, 배려를 핵심 가치로 삼아 변화되기 시작하였으며, 제3차 식생활교육 기본 계획(2020년-2024년)에서는 지속가능한 식생활로 함께 하는 농업, 건강한 국민, 포용하는 사회 실현을 비전으로 제시하고 있다. 그러나 4차 산업혁명의 디지털 문명은 학교 식생활교육에도 큰 영향을 미치고 있다. 따라서 이 연구에서는 우리나라 학교 식생활교육에서 지속가능한 식생활교육 내용을 살펴보고, 4차 산업혁명으로 인한 교육의 디지털 전환에 직면한 식생활교육 현상을 진단하고, 지속가능한 식생활 역량 함양을 위하여 포용적 식생활교육 구조와 내용 체계의 구체성을 통해 포용적 식생활교육의 방향을 탐색하였다. 포용적 식생활교육을 위해서는 인지적 학습, 정의적 학습, 실천적 학습이 포용적 방식으로 융합될 수 있는 구조와 체계가 필요하며, 지속가능한 식생활교육을 실천하기 위해서는 학습자 핵심 역량 함양에 중점을 두는 포용적 식생활교육의 방향에서 그 대안을 마련해야 할 것이다.

The Good Agriculture Practice (GAP) program, being established in China, is an optimal way for the sustainable utilization of the medicinal plant and animal resources. Most frequently used Chinese materia medica will be mainly produced from the GAP bases in the future. To assure the successful operation of GAP program, standard operating procedure (SOP) should be implemented for specific plants or animals. Both GAP and SOP include the requirements in many aspects from the ecological environment of cultivation place, germplasm and varieties, seedling and transplant, fertilization, irrigation, and field care, to harvest and process, package, transport and storage. As a complex system, GAP demands strong commitment from the pharmaceutical industry, local administrative involvement, long term R&D support, and years of time of development before a satisfactory result can be achieved.

Climate change is one of the major issues in both the developed and developing world. Greenhouse gas (GHG) emission is one of the implications for climate change. It is increasing rapidly. Although the emission is much less when compared to the rest of the world, Ethiopia has also faced this global issue. The major source for GHG emission in Ethiopia is agriculture. Therefore, the agriculture sector has to be given more attention in Ethiopia. To overcome the problem, Climate-Resilient Green Economy (CRGE) strategy has been initiated. One way of executing this target is to create a sustainable and environmentally friendly pathway to use agricultural byproducts. Sugarcane is one of the major plants in Ethiopia. Its byproducts are bagasse, molasses, and press mud. Since it is a waste product, it is economical and creates a sustainable and green environment by reducing GHG emissions. Sugarcane byproducts have versatile applications like as fuel, as cement replacing material, as a mitigation for expansive soils, as biosorbent for the treatment of water and wastewater and also as a wood material. However, Ethiopia has not used this byproduct massively as it is readily available. This paper reviews the possible applications of sugarcane byproducts to mitigate climate change.

Chlorella, one single-cell green algae organism that lives autotrophically by photosynthesis, can directly suppress some plant diseases. The objective of this study was to determine whether pre-spraying with Chlorella fusca suspension could induce systemic acquired resistance (SAR) in cucumber plants against anthracnose caused by Colletotrichum orbiculare. In order to illustrate SAR induced by algae, infection structures in host cells were observed under a transmission electron microscope (TEM). Cytological changes as defense responses of host mesophyll cells such as accumulation of vesicles, formation of sheath around penetration hyphae, and thickness of cell wells adjoining with intracellular hyphae were demonstrated in cucumber leaves. Similar defense responses were also found in the plant pre-treated with DL-3-aminobutyric acid, another SAR priming agent. Images showed that defense response of host cells was scarcely observed in untreated leaf tissues. These cytological observations suggest that C. fusca could induce SAR against anthracnose in cucumber plants by activating defense responses of host cells.

The management of municipal solid waste (MSW) is essential for every community; and, it is currently a major challenge in Nigeria. This paper provides an overview of the current MSW management trends in Nigeria and proposes new sustainable MSW management systems. Across Nigerian cities, MSW management is characterized by inefficient collection and transportation to disposal sites. Collection services do not reach some unplanned areas and slums due to poor street network. Even some planned areas are not reached by collection services. The informal sector contributes to waste collection, resource recovery and recycling; however, their activities are not recognized by the governments. Markets exist for recovered materials but more efforts need to be geared towards intensive recovery of materials and expansion of these markets. Despite the high proportion of putrescible matter in MSW, the only form of treatment commonly used currently is open burning for volume reduction. The high organic fraction presents a great opportunity for composting and anaerobic digestion. Ultimate disposal is currently done in open dumpsites. This needs to be upgraded to engineered landfills that are properly sited and adequately operated by well trained personnel. There is an emerging waste stream of concern, electronic-waste (e-waste), that requires urgent sustainable management as e-waste are currently co-disposed with other waste streams or burnt in the open posing detrimental health impacts.

This study compares and contrasts the Wales and England Organic Action Plans (WOAP and EOAP) and a Korean regional Life-Food Development Plan (KLFDP) in order to facilitate the development of the organic sector in Korea. Early action plans, for example, the first WOAP (1999) focused support on developing the supply of organic products whereas later action plans focused on marketing and consumer. OAPs may not only provide specific issue-solving roles by proposing new policy measures but also perform a regulatory role as a controller for organic sector development as a whole. The current KLFDP seems to stick to the former role but hardly has the latter role such as setting priorities, harmonizing various conflicting policy measures and factors and performing evaluation process for further progress. To secure better harmonized and sustainable development of Korean organic farming sector, constructing comprehensive national-level organic action plan, which has policy developing, implementing, regulating, evaluating and evolving functions, might be the most efficient choice.
