Analysis of recent land management initiatives in Nicaragua from the perspective of the "ecosystem approach".

In the world there are approximately 608 million farms, of which 84% are small farms and produce 35% of the food of the world population. Training programs have been promoted by different organizations to achieve a more sustainable and efficient agricultural practice. Within this context, this article has classified a set of smallholders located in central Nicaragua with regard to how they apply Land Use Management Initiatives (LUMI). The aim is to outline their weaknesses and strengths and thus identify key elements that can contribute to improving soil resource management. We focus on the LUMI carried out in Nicaragua in the municipalities of El Tuma-La Dalia, El Cuá and Waslala between 1992 and 2022. To conduct this study, eight LUMI were identified and analysed, and 25 indicators linked to the Malawi Principles were extracted and selected for the design of a survey in order to collect land use management information from 455 farms in the study area. Simple random sampling was used to select the farms. Subsequently, the collected data were analysed using descriptive statistics and Multivariate Analysis techniques. The results reveal that in the study area, the LUMI incorporate between one and five Malawi Principles. The multivariate analysis techniques employed identified three clusters of farms, with either Active, Moderate or Improvable ecosystem management. The study area as a whole displays strengths in social participation, local capacity building, soil and environmental conservation practices, with the farm as the main source of income. Weaknesses lie in the fact that indicators referring to household income and productivity are less frequent. In terms of farm management, the results revealed that combined male and female management was similar in percentage to male-only management. The results highlight the need to continue with the implementation of environmental goals linked to the design of initiatives that promote productivity, income and gender equity in farm management in an integrated manner. At the same time, existing local capacities for sustainable soil and ecosystem management should be brought together and strengthened.

Set of indices to assess dune development and dune restoration potential in beach-dune systems on Mediterranean developed coasts.

The purpose of this paper is to contribute with a tool to guide decision makers with some level of understanding of coastal dynamics as to the most appropriate management measures to adopt. A set of indices for assessing beach-dune systems and their potential for dune restoration are presented. The systems analysed are described using variables related to physical and anthropic factors, and the sites are classified according to the intervention actions required. Fifty beach-dune systems representing the range of types of beaches, the degree of urbanisation, and the dune morphologies found on the Catalan coastline (NE Iberian Peninsula) are sampled. The results show that beaches with the most developed dunes usually have high scores for management and low scores for urbanisation, while the less developed dunes are found on beaches with very low scores for management. Regarding the potential for dune restoration, the beaches are classified into four groups according to the management measures recommended: dune conservation, dune restoration, dune recovery, and renaturalisation of beaches where only incipient dunes can be developed.
