Land degradation in Australia is a persistent national problem. Australian governments, in partnership with community groups, are addressing land degradation through initiatives such as the Decade of Landcare Plan and the National Landcare Program (NLP). The NLP has funded over 3500 projects, through various sub-programs since the start of the Decade of Landcare in 1990. The Commonwealth Government is currently evaluating these programs as Australia enters the middle of the decade. To assist this evaluation, the Bureau of Resource Sciences has developed a spatial information system - LANDCARE GIS - to provide an integrated analytical approach. LANDCARE GIS has been used to identify and analyse the spatial relationships between the NLP, land resource condition and land use practices. It presently contains five main categories of data including: details of projects; national and State surveys of land condition; State surveys of landcare groups; surveys of landcare and land management practices; and other resource, biophysical and socio-economic data. LANDCARE GIS is one of the first examples of spatial information technology developed for the evaluation of Australian Government programs and policies. It is able to provide information on the effectiveness of programs and on the strategic allocation of resources within priority areas. A preliminary assessment of landcare activities is described, including (i) descriptions of NLP activities, (ii) the extent to which the NLP is targeting land degradation problems, (iii) a comparison of landcare and non-landcare farmer management practices, and (iv) an analysis of farmers' perceptions of land degradation. Many Australian Government departments are now adding geographic information systems (GIS) to their management 'tool kits'.
澳大利亚的土地退化是一个长期存在的全国性问题。澳大利亚政府与社区团体合作,通过“土地护理十年计划”和“国家土地护理计划”(NLP)等举措来解决土地退化问题。自 1990 年“土地护理十年计划”开始以来,NLP 通过各种分计划资助了 3500 多个项目。目前,澳大利亚已进入这十年的中期,联邦政府正在对这些项目进行评估。为了协助这一评估,资源科学局开发了一个空间信息系统——土地护理地理信息系统(LANDCARE GIS),以提供一种综合分析方法。LANDCARE GIS 用于确定和分析 NLP、土地资源状况和土地利用实践之间的空间关系。它目前包含五个主要类别的数据,包括:项目详细信息;国家和州土地状况调查;州土地护理团体调查;土地护理和土地管理实践调查;以及其他资源、生物物理和社会经济数据。LANDCARE GIS 是为评估澳大利亚政府计划和政策而开发的空间信息技术的首批示例之一。它能够提供有关计划有效性以及在优先领域内资源战略分配的信息。文中描述了土地护理活动的初步评估,包括(i)NLP 活动的描述,(ii)NLP 针对土地退化问题的程度,(iii)土地护理和非土地护理农民管理实践的比较,以及(iv)农民对土地退化看法的分析。现在,许多澳大利亚政府部门正在将地理信息系统(GIS)添加到其管理“工具包”中。
