“…Below is a selection of said variables that will help to identify the factors influencing LA21 planning approaches. Based on [22,24,26,27], among others, LA21 presents the following difficulties and challenges: non existence of real interdisciplinarity at municipal level, giving rise to sector type adjustments which do not include an integral, interconnected vision of the problems; inadequate organisational structure at local government level; weak participative tradition and limited tradition of collective responsibility; insufficient investment (of economic, material and human resources) in the participative processes as opposed to other dimensions; many LA21 led by elected political representatives and even external agents (as private consultants); compelling and urgent need to resolve everyday problems demanded by citizens and stakeholders which detracts from the ability to reflect, debate, participate and plan; scanty contribution from social networks, especially business organisations; lack of political leadership and consensus in town councils, and short-term vision; decision-making on local issues taken at other levels, with no clear definition of the role of supramunicipal entities; lack of training for technical experts and politicians on sustainability issues; a planning and programming vocation based on an exhaustive diagnostic of the territory, with expert knowledge taking precedence over others (methodologies oriented at developing intangibles such as knowledge, social relations and empowerment are rarely applied); need for flexible implementation and monitoring systems.…”
