<strong>The</strong> <strong>Local</strong> <strong>Agenda</strong> <strong>21</strong> <strong>Planning</strong> <strong>Guide</strong><br />

Conclusions<br />

Risk-based priority setting has demonstrated that effective environmental management emanates not from the technical and<br />

quantitative information generated, but from the application of this information in a consensual priority-setting process.<br />

Risk-based priority setting has some limitations. By focusing the analysis of problems on the identification of present problems, the<br />

method can overlook opportunities to prevent risk in the first place. In addition, in some contexts increased emphasis should be put<br />

on future risk. Trends in rates of population growth, land use, and natural resource depletion may be so severe that the scale and<br />

impact of a given environmental problem in the future may vary drastically from the current risks these pose. By systematically<br />

comparing and setting priorities in a limited set of problems, risk-based priority setting also does not promote a systemic analysis of<br />

problems and can result in short-term symptomatic treatment. Finally, risk-based priority setting does not explicitly analyze and<br />

promote institutional reform of structures that contribute to the perpetuation of fundamental problems.<br />

Background<br />

Troyan is a community of 46,000 people located 54 kilometers east of Sofia, the capital of Bulgaria, in the northern foothills of the<br />

Balkan Mountains. Troyan is located at the edge of a biosphere reserve and national park. Environmental problems have<br />

compromised Troyan’s natural beauty and economic prosperity. Severe shortages of potable water are common and it is rationed in<br />

the summer and fall. Water quality is poor and cases of dysentery are common. Troyan’s drinking water comes from an upriver<br />
