Assessing Land Dynamics and Sustainability on the Pacific Coast of Nicaragua: A Method Based on Comprehensive Land Units

In the coastal zones, varied uses converge, some of them of priority interest. In this study, an integrated method for the planning and management of the territory is proposed, which includes the evaluation of sustainability. A total of 15 different land-use classes were estimated in 80 sampling units distributed regularly along the Pacific coastline of Nicaragua and classified to determine land management sectors. For each of the identified sectors, the ecological, economic, social, and productive dimensions were evaluated independently, handling a total of 53 variables from different databases, by means of ordination multivariate factor analysis. Subsequently, the four dimensions were integrated into a model and the results were evaluated based on their similarity with theoretical development scenarios, assessed by discriminant analysis. Among these, the scenarios considered as a goal for sustainability in the studied area were present. On the Pacific coast of Nicaragua, productive and economic activities are currently prioritized, without having an integrated planning scheme for the entire territory, which includes nature conservation. The main contribution has been to provide a method for evaluating the land in an integrative and multidimensional way, while at the same time qualifying the different territorial sectors from a sustainable development. Even under a context of relative scarcity of information for some relevant aspects, the dimension-values assessment is largely solved by ordering the territorial sectors with a multivariate strategy, so that they are classified in relative and not absolute terms, which allows the strategy to be very useful for countries lacking some databases and cartography. This holistic and comprehensive vision of the entire territory facilitates social participation and contributes to decision-making aimed at advancing toward sustainability.
