tailieunhanh - Integrated Assessment of Health and Sustainability of Agroecosystems - Chapter 8

Mục tiêu chung của nghiên cứu này là để thực hiện một đánh giá tổng hợp về sức khỏe và tính bền vững sinh thái nông nghiệp với trọng tâm đặc biệt ở các trang trại quy mô nhỏ ở vùng cao nguyên trung tâm của Kenya (Chương 1). Khuôn khổ sinh thái nông nghiệp y tế được thành công phù hợp để sử dụng trong một Hệ sinh thái nông nghiệp quy mô nhỏ chiếm ưu thế (Chương 2). Phương pháp có sự tham gia (Chương 3), phân tích hệ thống (Chương 4), phương pháp hệ thống phần mềm. | 8 General Discussion SYNOPSIS The general objective of this study was to carry out an integrated assessment of agroecosystem health and sustainability with special focus on smallholder farms in the central highlands of Kenya Chapter 1 . The agroecosystem health framework was successfully adapted for use in a smallholder-dominated agroecosystem Chapter 2 . Participatory methods Chapter 3 systems analyses Chapter 4 soft systems methods Chapter 5 and conventional research approaches were combined in an open-ended adaptive research-and-development process. Two suites of health and sustainability indicators were developed. The first suite which was community driven enabled farmers and communities to assess the health and sustainability of their own agroecosystem. The second suite was research based and complemented the community-driven suite. This was used to assess the potential impact of community goals on health and sustainability of the Kiambu agroecosystem. Pulse process models Chapter 4 were used in these assessments. Correspondence analysis was used to refine the research-based suite of indicators Chapter 6 as well as to analyze data obtained using indicators Chapter 7 . SUSTAINABILITY Communities cognitive maps Chapter 4 and descriptions of their vision of a healthy and sustainable future Chapter 6 seem to indicate that they perceive sustainability as resulting from accelerated economic development. They do not perceive resource stocks as consumable piles but rather as consisting of renewable and nonrenewable portions with capacity for regeneration if the system is properly utilized. Their descriptions seem to indicate that they perceive it possible to gainfully and sustainably increase the utilization of their agroecosystems presumably through the use of technology to realign the way resources are utilized and to support the agroecosystem status and function. The growth concept of sustainability seems to be the most congruent with community perceptions.
