  • The elements that determine the success of development projects on goats and the prerequisites for ensuring this are discussed in the context of the bewildering diversity of goat genetic resources, production systems, multifunctionality, and opportunities for responding to constraints for productivity enhancement. Key determinants for the success of pro-poor projects are the imperatives of realistic project design, resolution of priorities and positive impacts to increase investments and spur agricultural growth, and appropriate policy. Throughout the developing world, there exist 97% of the total world population of 921 million goats across all agroecological zones (AEZs), including 570 breeds and 64% share of the breeds. They occupy a very important biological and socioeconomic niche in farming systems making significant multifunctional contributions especially to food, nutrition and financial security, stability of farm households, and survival of the poor in the rural areas. Definitions are given of successful and failed projects. The analyses highlighted in successful projects the value of strong participatory efforts with farmers and climate change. Climate change effects on goats are inevitable and are mediated through heat stress, type of AEZ, water availability, quantity and quality of the available feed resources and type of production system. Within the prevailing production systems, improved integrated tree crops - ruminant systems are underestimated and are an important pathway to enhance C sequestration. Key development strategies and opportunities for research and development (R and D) are enormous, and include inter alia defining a policy framework, resolution of priority constraints using systems perspectives and community-based participatory activities, application of yield-enhancing technologies, intensification, scaling up, and impacts. The priority for development concerns the rainfed areas with large concentrations of ruminants in which goats, with a capacity to cope with heat tolerance, can be the entry point for development. Networks and networking are very important for the diffusion of information and can add value to R and D. Well formulated projects with clear priority setting and participatory R and D ensure success and the realisation of food security, improved livelihoods and self-reliance in the future.

  • Discourses on global environment are not only limited to the matter of simple environmen-tal protection but also going to an imperative that every country should take the environ-mental aspects into more consideration, and if necessary even proceed to modify its own strategies for economic growth. It is because scores of existing International conventions and agreements on environmental caused tend to combine the environmental issues with trade sanctions and financial assistances in order to ensure a mandatory power in pushing themselves through on a global dimension. Particularly noteworthy is the so -called Green Round(GR) which substantially associates the Issues of environmental protection with some sanctions in international trade, its rationale is quite simple. The differentiated production costs rising from the difference in environmental standards among different countries may affect national competitiveness in in-ternational trade, therefore a need does exist to countervail this difference. In reality, however, severe dissention seems to have been exposed between the developed and developing countries around this matter, because national interests and priorities in national goals considerably differ among respective countries. Greenhouse gases such as carbon dioxide which caused global warming are mostly released from the combustion of fossil fuels. The perfect removal of released $CO_{2}$ is impossible with existing technologies, and moreover, it's not payable in economical terms. Therefore it will be more effective and desirable to make more efforts to prevent the release of the $CO_{2}$ it- self through energy conservation involving the development and promotion of clean and high-efficient energy technologies and energy sources, and the development and promotion of new & renewable energy resources, and so on. One of important national tasks In our country is to establish an Energy Policy consider-ing environmental impacts since Korea depends most of its energy consumption on the fossil fuels such as oil and coal.

  • This mini review examines the habitat connectivity and effectiveness of Korean Marine Protected Areas (MPAs) in the Yellow Sea Large Marine Ecosystem (YSLME) region. We first reemphasize that the Korean region of the YSLME is a single ecosystem (ecoregion) given the biophysical distribution patterns. The MPAs within the YSLME contribute about 50% to the total MPAs in Korea, accounting for about 10% of the territorial sea waters of Korea and 20% of the waters of YSLME on the Korean side. By area, national parks account for nearly 45% of the MPAs, followed by the wetland protected areas at 25%, with other types of MPA comprising the remaining 30%. Large MPA (> 100 km2) is the dominant type of MPA, accounting for 90% of the total area. We find that MPAs in the region are connected physically and perhaps also genetically. However, the level of protection was found to be low, and a no-take zone is rarely implemented. In addition, interrupted freshwater discharge caused by river-mouth dams poses a major hindrance to the physical connectivity of the MPAs. Restoration of the river-mouth dams and strengthened regulation on MPAs, with further expansion of MPAs in line with the current development of post-2020 global biodiversity frameworks, should be priorities for better management of marine resources. The newly revised law incorporating the concept of "Marine Ecosystem Axis Management" would reinforce the processes, and their effectiveness together with overall management of MPAs in Korea should be evaluated by designing appropriate measurement tools.

  • 최근 환경부의 야생동 식물법의 멸종위기 야생식물I급과 II급에 해당하는 종들은 멸종이라는 용어를 사용하면서 국내(남한)에 분포하는 자료나 빈도를 중심으로 취합한 자료로서, 전세계적으로 감소 추세 및 위협요인에 대한 정보가 없거나 반영하지 않은 경우이다. 본 연구는 전세계 범주에서 IUCN 적색목록의 정확한 범주(category)와 평가기준(criteria)으로 64종에 대한 평가를 실시하여 4개 유형(Groups I-IV)으로 나누었다. 동북아사이에 매우 넓게 분포하면서 우리나라 일부 집단에서만 발견되는 분류군으로서 멸종과는 전혀 관련이 없는 종(Group I, 28종, 43.8%), 일본이나 중국에서 희귀식물로 판정하여 국지적으로는 멸절위기에 있지만 다른 국가에서는 매우 흔하게 분포하거나 혹은 멸종 위협이 낮은 분류군(Group II, 5종, 7.83 %), 우리나라에만 분포하면서 집단내에서 개체수가 감소하거나 집단이 환경적 요인에 의해 위협을 받고 있는 진정한 멸종위협 식물로 판정되는 식물(Group III, 15종, 23.4%), 현재 알려진 정보에 의하면 우리나라에서도 멸절위험이 있을 뿐만 아니라 중국, 러시아 등지에서도 희귀해서 전세계적 수준에서 IUCN 평가를 통해 IUCN 적색목록에 등재될 가능성이 있는 분류군 (Group IV, 16종, 25.0%)등으로 확인되었다. 이중 적색목록에 의해 평가한 15종 (Group III)중 5종은 CR, 3종은 EN, 4종은 UV, 3종은 DD로 평가되었고, Group IV의 16종은 DD로 평가하였다. 따라서, 환경부의 멸종위기 식물 I과 II등급중 약 33종(Group I+ II)은 최소한 등재 목록에서 제외하는 것이 바람직하다. 이런 문제점은 목록을 작성한후 국가적으로 기초 자료 수집 단계에 대한 정책의 일관성이 없고, 또한, 목록화에 대한 이의제기에 의한 재평가 제도가 없어 정책의 과학적 진보와 수정을 원천적으로 차단하는 닫힌 정책이 원인이다. 따라서 현재 환경부에서는 목록을 새로 정비할 필요가 있으며, 이런 목록을 수정하는 과정에서 전세계 수준에서 멸종위기 식물을 목록화가 필요하다. 특히, 목록 작업이 완성되면 해당 분류군에 대한 기본적인 자료 수집과 장단기 조사과정으로서, 해당 분류군에 대한 멸종위협 요인을 수집하고, 이 자료를 근간으로 정량적으로 IUCN 적색목록 평가방식이 추진할 필요가 있다.

  • The availability and efficient use of the feed resources in Asia are the primary drivers of performance to maximise productivity from animals. Feed security is fundamental to the management, extent of use, conservation and intensification for productivity enhancement. The awesome reality is that current supplies of animal proteins are inadequate to meet human requirements in the face of rapidly depleting resources: arable land, water, fossil fuels, nitrogenous and other fertilisers, and decreased supplies of cereal grains. The contribution of the ruminant sector lags well behind that of non-ruminant pigs and poultry. It is compelling therefore to shift priority for the development of ruminants (buffaloes, cattle, goats and sheep) in key agro-ecological zones (AEZs), making intensive use of the available biomass from the forage resources, crop residues, agro-industrial by-products (AIBP) and other non-conventional feed resources (NCFR). Definitions are given of successful and failed projects on feed resource use. These were used to analyse 12 case studies, which indicated the value of strong participatory efforts with farmers, empowerment, and the benefits from animals of productivity-enhancing technologies and integrated natural resource management (NRM). However, wider replication and scaling up were inadequate in project formulation, including systems methodologies that promoted technology adoption. There was overwhelming emphasis on component technology applications that were duplicated across countries, often wasteful, the results and relevance of which were not clear. Technology delivery via the traditional model of research-extension linkage was also inadequate, and needs to be expanded to participatory research-extension-farmer linkages to accelerate diffusion of technologies, wider adoption and impacts. Other major limitations concerned with feed resource use are failure to view this issue from a farming systems perspective, strong disciplinary bias, and poor links to real farm situations. It is suggested that improved efficiency in feed resource use and increased productivity from animals in the future needs to be cognisant of nine strategies. These include priorities for feed resource use; promoting intensive use of crop residues; intensification of integrated ruminant-oil palm systems and use of oil palm by-products; priority for urgent, wider technology application, adoption and scaling up; rigorous application of systems methodologies; development of adaptation and mitigation options for the effects of climate change on feed resources; strengthening research-extension-farmer linkages; development of year round feeding systems; and striving for sustainability of integrated farming systems. These strategies together form the challenges for the future.

  • The integrated solid waste management for Seoul Metropolitan city can be established on the basis of the following hierarchy of priorities: 1. Efforts for source reduction should be propelled by both government and citizens to achieve the effects of resource conservation. The adequate production and consumption which are environmentally amenable and sustainable can be induced by the reasonable imposition of deposit money for waste treatment to one-time use products. To accomplish source reduction effectively, the induction of legal and institutional regulation of producer and consumer participation is requisite. 2. For resource recovery, wastes generated should be recycled as far as practicable. Community residents are responsible to separate discharge, the authorities concerned have responsibility of separate collection, and recycling industry should be assissted through tax reduction and financing. Resource separation facilities can be constructed at Kimpo Metropolitan landfill site for wastes not separately collected due to some unavoidable circumstances. 3. Garbage should be composted. Garbage is uneconomical for incineration, because it has high moisture content and low calorie, thus there is no reason for the incineration of garbage even though garbage is classified into combustibles. Composting facilities can be located at sites which are not densely populated and easily accessible to transportation, for example, Kimpo Metropolitan landfill site. Compost produced can be managed by the authorities for the use of fertilizer to a green tract of suburban land and farms. 4. Nonhazardous combustible wastes not recyclable can be utilized for thermal recovery at the incinerators which are completely equipped with pollution control devices. According to the trend of local autonomy and the equity principle of local autonomous entities, incineration facilities of minimal capacity required can be constructed at each districts of Seoul Metropolitan city which have organized local assembly. In case of Yangcheon district, the economically combustible waste quantity is about 260 tons/day which exceeds 150 tons/day, the incineration capacity of existing facility. But, from now on, waste quantity can be reduced substantially by the intensive efforts of citizens for source reduction and recycling and the institutional support of administrative organizations. Especially, it is indispensable for the government to constitute institutional and technological bases that can recycle paper and plastics form 43% of waste generated. A good time for constructing of incineration facilities for municipal solid waste can be postponed to the time that pollution control technologies of domestic enterprises are fully developed to satisfy the standards of air pollution prevention, because the life expectancy of Kimpo Metropolitan landfill site is about 25 years. Within this period, institutional improvements and technological advancements can be attained, while the air qual. ity of Seoul Metropolitan city can be ameliorated to the level to afford incineration facilities. 5. For final disposal, incombustibles and ash are landfilled sanitarily at Kimpo Metropolitan landfill site.

  • Urban problems are constantly occurring around the world due to rapid industrialization and population decline. In particular, as the number of vacant houses is gradually increasing as the population decreases, it is necessary to prepare countermeasures. A plan to utilize vacant houses has emerged to restore the natural environment of the urban ecosystem where forest destruction, damage to habitats of wild animals and plants, and disconnection have occurred due to large-scale development. Through connectivity analysis, it is possible to understand the overall ecosystem flow based on the movement of species and predict the effect when vacant houses are converted into green spaces. Therefore, this study analyzed the green area network to confirm the possibility of greening of vacant houses neglected in Jeonju based on circuit theory. Using Circuitscape and Least-cost path, we tried to identify the connectivity of green areas and propose an ecological axis based on the analysis. In order to apply the resistance values required for analysis based on previous studies, the 2020 subdivision land cover data were integrated into the major classification evaluation items. When the eight forests in the target site were analyzed as the standard, the overall connectivity and connectivity between forests in the area were high, so it is judged that the existing green areas can perform various functions, such as species movement and provision of habitats. Based on the results of the connectivity analysis, the importance of vacant houses was calculated and the top 20 vacant houses were identified, and it was confirmed that the higher the ranking, the more positive the degree of landscape connectivity was when converted to green areas. In addition, it was confirmed that the results of analyzing the least-cost path based on the resistance values such as connectivity analysis and the existing conceptual map showed some differences when comparing the ecological axes in the form. As a result of checking the vacant houses corresponding to the relevant axis based on the width standards of the main and sub-green areas, a total of 30 vacant houses were included in the 200m width and 6 vacant houses in the 80m width. It is judged that the conversion of vacant houses to green space can contribute to biodiversity conservation as well as connectivity between habitats of species as it is coupled with improved green space connectivity. In addition, it is expected to help solve the problem of vacant houses in the future by showing the possibility of using vacant houses.
