Abstract
The Evaluation Model of Multi-use Appropriateness of Marginal Agricultural lands For adapting to the issues of trade liberalization and food security, many countries with advanced agriculture have been gradually progressing revolutions of agriculture and farmland policies to promote agricultural competitiveness, stabilize farmers’ income and ensure the sustainable use of agricultural land resources. Because the agricultural land was expanded from its simple economic function of food production to the multifunctionality for promoting quality of life and maintaining ecological environments, to properly maintain agricultural land resources is the utmost importance to manifest ecological and cultural multifunctions of agriculture. Therefore, build appropriate multi-use strategy for marginal agriculture lands is necessary and urgent. However, the appropriation of strategy should be based on the potential of local place. The aim of this project is to propose the analytical framework of multi-use strategy for marginal agriculture lands, through the case study we try to draw up the coordinated sets of measures of the multi-use of marginal agriculture lands for the chosen-area in this project. Tasks and contents of this project will include: 1. to summarize the international literature and measures of marginal agricultural land. 2. to explore the indicators of marginal agriculture lands for our country, for example, the productivity, impact level of environment and social and economic factors. 3. to build an analytical framework for multi-use of margina agricultural land, and apply it on an area, based on the results we will draw up the coordinated sets of measure for multi-use of marginal agricultural land in Taiwan. The accomplishment of this project is expected to provide strategies of multi-use of agricultural land and suggestions for adjusting the existing agricultural land policies and practices. This will benefit to reach a rational use of marginal agricultural land in Taiwan. A Study on Multifunctional Value Loss and Compensation Mechanism for Farmlands Programs Objectives (2017)This study intends to collect and review foreign and domestic literature and systems concerning multifunctional value assessment and ecological (environmental) compensation for armlands. From the multifunctional perspective of farmlands, this study investigated the methods for assessing multifunctional value loss of farmlands caused by illegal occupation, improper use or change of use of farmlands in Taiwan, as well as performed case analyses. Moreover, according to the assessment results of empirical model, this study developed the ecological (environmental) compensation mechanism for loss or pollution of farmlands, as well as other supporting measures for reducing impacts. Furthermore, this study proposed suggestions on existing policies of farmlands. Structure (Important Work in 2017)1.To arrange and analyze foreign and domestic literature and systems concerning multifunctional value assessment and ecological (environmental) compensation for farmlands. 2.To investigate the methods for assessing multifunctional value loss of farmlands caused by illegal occupation, improper use or change of use of farmlands in Taiwan and to perform case analyses. 3.To develop the ecological (environmental) compensation mechanism for loss or pollution of farmlands, as well as other supporting measures for reducing impacts.4.Topropose the suggestions on existing policies of farmlands.5.To hold 2 forums with scholars and experts to summarize their comments as reference for this study. Expected Benefits1.To complete the assessment and analysis of multifunctional value loss of farmlands. 2.To develop the ecological (environmental) compensation system for loss and pollution of farmlands and other supporting measures for reducing impacts. 3.To hold at least 2 forums to exchange and discuss with experts and scholars in relevant fields. Study on the Model of Development of Agricultural Industry for Agricultural Zone in Urban Planning District In the past, agricultural zone in urban planning district is often regarded as land reservation for urban development. The needs of the farming industry were seldom taken into consideration in the planning and usage of farmlands. In Japan, via the Basic Law on the Promotion of Urban Agriculture of Japan, emphasis is put on city farming to provide multiple functionalities such as fresh produce, leisure agriculture, air purification, and water preservation. In this project, we propose to study the development, positioning, and improvement of agricultural zone in urban planning district and agricultural land in the vicinity of developments, in order to preserve the agricultural resources. The work items include: 1. Analyze the laws of urban agriculture and methods of development of agricultural industry in Japan as references for our development. 2. Study the status of agricultural zone in urban planning district and agricultural land in the vicinity of developments. 3. Case study of the development of agricultural land; comparative study of the benefits and improvements. 4. Propose of supplementary measures for agricultural land management. 5. Hold two seminars to gather opinion from experts. The Establishment of Classified Management of Water and Soil Resourcesand Early Warning Mechanism As a result of the unbalanced rural and urban planning and development, many farming communities are threatened by wastewaters from industrial, livestock, and domestic sources, which have caused damages to agricultural production and endangered food safety and human health. In view of this, the effective monitoring of irrigation water quality, integrative management of water resources, and effective management of regional farmland have become urgent and critical issues. In this project, the major task is to establish hierarchical indicators to classify the quality of farmlands, and to develop zoning management strategies of farmlands. In order to earmark funds of government effectively. For regions under risk of heavy metals pollution, we also plan to evaluate transport pathways of contaminants between irrigation water, sediment and soil in order to analyze the agricultural tolerance capacity of pollutants. In addition, we also plan to evaluate analyze method of anion time-lapse ion-exchange resin capsules, to expand the use of the time-lapse ion-exchange resin capsules on the monitoring of heavy metals concentrations of irrigation water. Finally, according to the research achievements that are mentioned above, to establish integrated management strategies of early warning system for the protection of agriculture environment.
