“…Expert knowledge incorporated into SEADSS's database queries was obtained by surveying agroforestry professional using questionnaires to determine the following: 1) desired morphological and habit characteristics of species for each agroforestry practice, 2) economic and environmental services obtained from an agroforestry system, and 3) optimal plant characteristics for different environmental services (e.g. erosion control) (Ellis et al 2000). SEADSS's intended end-users are landowners and extension agents, and their inputs and participation are essential during the validation and evaluation process.…”

Successful design of agroforestry practices hinges on the ability to pull together very diverse and sometimes large sets of information (i.e., biophysical, economic and social factors), and then implementing the synthesis of this information across several spatial scales from site to landscape. Agroforestry, by its very nature, creates complex systems with impacts ranging from the site or practice level up to the landscape and beyond. Computer-based Decision Support Tools (DST) help to integrate information to facilitate the decision-making process that directs development, acceptance, adoption, and management aspects in agroforestry. Computer-based DSTs include databases, geographical information systems, models, knowledge-base or expert systems, and 'hybrid' decision support systems. These different DSTs and their applications in agroforestry research and development are described in this paper. Although agroforestry lacks the large research foundation of its agriculture and forestry counterparts, the development and use of computer-based tools in agroforestry have been substantial and are projected to increase as the recognition of the productive and protective (service) roles of these tree-based practices expands. The utility of these and future tools for decision-support in agroforestry must take into account the limits of our current scientific information, the diversity of aspects (i.e. economic, social, and biophysical) that must be incorporated into the planning and design process, and, most importantly, who the end-user of the tools will be. Incorporating these tools into the design and planning process will enhance the capability of agroforestry to simultaneously achieve environmental protection and agricultural production goals.

“…Geographic Information System (GIS) enables the users to explore spatial data visually, allowing specialized searches on, and analysis of, both spatial and non-spatial (attribute) data. With the increasing use of geographical data in real-world applications GIS has been widely used in various types of business, government and university projects and has emerged as a fruitful area for research [1,2]. In recent years, as the use of the Internet became more widespread there came a remarkable growth in web-based GIS(WebGIS), which allows geographic information to be received, visualized, shared, and analyzed through Internet.…”

WebGIS serves as an important means of communicating, conveying and presenting geographical information and knowledge to the public through Internet. However, due to its technical complexity and inability of tailored functions, communities lacking the expertise and resources cannot make full use of this technology. This paper presents a novel development approach for WebGIS based on dynamical integration of distributed components technology, which is potential to overcome the problems. WebGIS applications developed with this approach can run at multi-mode, including stand-alone and network, and allows users to add expected GIS components to the system at run time. The mechanism of each working mode is explained and key technologies supporting the mechanism are discussed. To validate feasibility of the approach, a prototype called FreeXGIS is proposed, and the architecture design and implementation of several elementary components of the FreeXGIS are discussed in detail. It provides a paradigm for developing WebGIS applications by employing distributed GIS components. Also several future works to enhance the performance and practicability of WebGIS developed with this approach are presented at last.

“…Remote sensing techniques have been utilized successfully in certain areas of application, including forestry, watershed management, agriculture and related fields, especially in developed countries where agriculture patterns are well defined and methodologies are developed. However, these technologies have yet to be used extensively in agroforestry 10 . In a spatial database approach, suitable areas for agroforestry were estimated in subSaharan Africa and suitable areas of Annona cherimola agroforestry system were determined in Southern Ecuador 11 .…”

Agroforestry is a traditional and ancient land use practice, having deliberate integration of trees with crop and livestock components. In India, agroforestry practices are prevalent in different agro-ecological zones and occupy sizeable areas. These practices have great potential for climate change mitigation through sequestration of atmospheric CO 2 . Carbon sequestration potential was studied in four districts of Gujarat (Anand, Dahod, Patan and Junagarh), for which field survey was conducted to collect primary data on existing agroforestry systems. The extent of agroforestry area in these districts was estimated by sub-pixel classifier using medium resolution remote sensing data (RS-2/LISS III). By sub-pixel classifier, the highest area under agroforestry was estimated in Dahod (12.48%) followed by Junagarh district (10.95%) with an average of 9.12%. Sapota (Manilkara zapota) based agroforestry was also mapped in Junagarh district, which occupied an area of 1.13%. An accuracy of 87.2% was found by sub-pixel classifier in delineation of sapota-based agroforestry in the district. Dynamic CO2FIX model has been used to estimate total carbon (biomass + soils) and net carbon sequestered in existing agroforestry systems. Net carbon sequestered over a simulated period of 30 years in Anand, Dahod, Patan and Junagarh districts was found to be 2.70, 6.26, 1.61 and 1.50 Mg C ha -1 respectively. Total carbon stock in all four districts for baseline and simulated period of 30 years was estimated to be 2.907 and 3.251 million tonnes respectively. Thus, agroforestry systems in Gujarat have significant potential in carbon storage and trapping atmospheric CO 2 into biomass and soils. Hence, CO2FIX model in conjunction with remote sensing techniques can be successfully applied for estimating carbon sequestration potential of agroforestry systems in a district or a region.
