Sustainable management of floods, catchments and river banks in Manabí province En Manabí las autoridades locales y nacionales han elaborado e implementando planes de gestión  de inundaciones; sin embargo, las inundaciones aún causan grandes daños frecuentemente. El objetivo de la presente investigación es explorar técnicas que se podrían aplicar en Manabí para un manejo sostenible de inundaciones (SFM). Dos objetivos específicos son: explorar los enfoques y técnicas para i) SFM basado en manejo de cuencas hidrográficas, y ii) SFM basado en manejo de ríos y riberas. Se realiza un análisis desde un punto de vista técnico, económico, social y ambiental. La revisión y el análisis revelan que, en cuanto a manejo de inundaciones basado en manejo la cuenca, existen proyectos y planes hidráulicos que han sido efectivos en cierta medida. Específicamente represas, muros para retención de escorrentía y encauzamiento de quebradas. Sin embargo, se ha venido dando un manejo inadecuado a las riberas de varios ríos. Sus taludes se limpian y quedan desprotegidos contra la erosión con posibles implicaciones para la sedimentación y el riesgo de inundación aguas abajo de las zonas intervenidas. Enfoques sostenibles incluyen la bioingeniería y la ‘ingeniería suave’. El presente análisis puede contribuir al debate sobre el camino a seguir para la gestión de inundaciones en la provincia.

Abstract In Manabí local and national authorities have implemented flood management plans; however, floods still cause major damages frequently. The objective of this research is to explore techniques that could be applied in Manabí for sustainable flood management (SFM). Two specific objectives are to explore the methods and techniques for i) SFM based on management of catchments, and ii)  SFM based on management of rivers and riverbanks. An analysis is undertaken from the technical, economic, social and environmental points of view. The review and analysis reveals that, regarding flood management based on catchment management, there are projects and hydraulic plans that have been effective to some extent. Namely: dams, runoff-retention walls and gully channelization and diversion works. However, an inadequate management has been given to the banks of many rivers. These river banks are cleaned and left unprotected against erosion, with possible implications for sedimentation and flood risk downstream of the intervened areas. Sustainable approaches include bioengineering and 'soft engineering'. The present analysis can contribute to the debate on the way forward for flood management in the province.

Hydrological Droughts

<p>In the context of proactive drought management plans, a key element consists of analyzing, selecting and allocating measures aimed at increasing resistance to droughts and reducing its potential impacts on the society, environment and economy. Currently, these measures, known as preventive drought management measures (Fatulová et al., 2015), are embedded within measures for flood management, catchment management plans, rural development plans, among others. This situation raises two issues. Firstly, information about potential preventive drought management measures (PDMM) is commonly fragmented and it is not a trivial task find or select measures that could be implemented as PDDM. Secondly, even though the same measure can be implemented from different management perspectives (Flood management, land degradation management, catchment management, rural development plans,) its applicability, advantages and limitations, may change according to the management perspective.</p><p>Considering the above, this study attempts to provide a review of PDMM that includes: measure description, applicability, limitations, mathematical representation (For further implementation in modelling systems) and classification, from a drought management perspective. It is worth to mention that this study is focused on hydrologically based measures, applicable for agricultural and hydrological drought management.</p><p>The research methodology is divided in three phases. The first phase consists of identifying drivers that trigger and/or enhance agricultural and hydrological droughts. This analysis is carried out from a hydrological angle, where land surface processes and human activities are potential drivers agricultural and hydrological droughts (Van Loon et al., 2016). The second phase examines an extensive list of technical documents, books, books sections, journal articles and case studies in order to identify those measures that could manage or mitigate the impact of potential drivers of agricultural and hydrological droughts. In this phase, PDMM are described in terms of applicability, advantages, limitations and mathematical representation for further implementation in modelling systems. Based on the analysis of the PDMM, the third phase of the study focusses on their classification, into three categories: nature-based solutions, grey infrastructure and changes in human water consumption</p>

Study Zone

Growing concern about the declining state of the catchment and river led to the formation of the Blackwood Basin Group in 1992. Funded primarily by the Natural Heritage Trust and using the river as the focus, the group aims to provide leadership and support to achieve sustainable management of natural resources in the catchment. Through an Integrated Catchment Management approach, the Blackwood Basin Group has managed a range of projects to improve the community's understanding and management of the Blackwood River and its catchment. A number of research, education, demonstration and on-ground action activities relating to river management have been undertaken in partnership with community and local, state and federal government organisations. Activities include demonstrations and evaluations of riparian restoration, funding riparian restoration activities, protection of high conservation value remnant vegetation, a flood risk study, zone action planning and monitoring the condition of the river and its tributaries.

Baseline Information

In this study, we evaluated stand status, dendrometric variables, and fruit production of Tamarind (Tamarindus indica L.) trees growing in bushland and farmland-use types in dryland areas of Ethiopia. The vegetation survey was conducted using the point-centered quarter method. The fruit yield of 54 trees was also evaluated. Tree density and fruit production in ha were estimated. There was a significant difference in Tamarind tree density between the two land-use types (p = 0.01). The mean fruit yield of farmland trees was significantly higher than that of bushland trees. However, Tamarind has unsustainable structure on farmlands. Differences in the dendrometric characteristics of trees were also observed between the two land-use types. Predictive models were selected for Tamarind fruit yield estimations in both land-use types. Although the majority of farmland trees produced <5000 fruit year−1, the selection of Tamarind germplasm in its natural ranges could improve production. Thus, the development of management plans to establish stands that have a more balanced diameter structure and thereby ensure continuity of the population and fruit yields is required in this area, particularly in the farmlands. This baseline information could assist elsewhere in areas that are facing similar challenges for the species due to land-use change.

In protected areas (PAs) in Bangladesh, as policies shift from net deforestation, conservation initiatives and various management plans have been implemented to reduce deforestation and include public participation at multiple levels. However, the interactive effect of land-related policies on deforestation in PAs is poorly understood. In this study, land-use change analysis using geographic information system data was performed to investigate how policies affected land use and land cover change in Rema-Kalenga Wildlife Sanctuary (RKWS), particularly the National Forest Policy (1979~), National Land Policy (2001~), and Agricultural Land Policy (1999~), using a series of Landsat images captured at different times. Our analyses showed that the total forest area increased in the 1994–2005 period when a plantation program was implemented, and also that many forest areas were replaced with noncommercial agricultural land areas in the 2005–2013 and 2013–2018 periods, when land zoning and co-management programs were implemented under different land-related policies. Commercial and non-commercial agricultural land expansions were the main drivers of deforestation, suggesting that several programs under the different land-related policies could have had synergetic effects on deforestation even in PAs. Our findings emphasize the importance of considering the undesirable effects of land-related policies in Pas, and the need to support the community for forest conservation.

Of Greece

Riparian areas, especially in the Mediterranean, offer many ecosystem services for the welfare of society benefits from their sustainable management. This study presents different tools used to assess riparian areas of Greece and their results. Riparian areas with different land-uses/vegetation covers along streams or torrents were assessed. The assessment tools were visual protocols, bioindicators, geographic information systems (GIS), vegetation indices, and a model. These tools differ in scale, accuracy, and difficulty of implementation. The riparian areas had Low and Moderate quality in Greece because of agricultural activities and hydrologic alterations. Vegetation appeared more important for the integrity of riparian areas than stream flow (perennial or intermittent). In addition, territorial variables (distance from dam and sea) were more influential compared to climatic variables. Visual protocols and GIS were effective for preliminary assessments. GIS can be applied at a greater scale but was less accurate than the protocols. Bioindicators can provide more cost-effective monitoring than physicochemical water variables. Finally, vegetation indices and models can be used for larger spatial and temporal scales, but require specialized personnel. Overall, riparian areas of Greece seem to be degraded, and monitoring would contribute to the development of a database on riparian areas that should form the basis for sustainable management plans in Greece.

Future Challenges

Water is a central resource supporting human activities and ecosystems and it is required for different purposes and uses that are often conflicting. Existing water-related problems are expected to increase and conventional water resource management systems are not likely to be able to face future challenges. There is the need for an integrated water resources management, which should be participatory, technically and scientific informed and which should be based on bottom-up approach. The Directive 2000/60/EC is based on principles of integrated planning and calls for stakeholder involvement in water management. Involving stakeholders is an important step to ensure that catchment management plans take into consideration local needs, experiences and interests. This paper presents a stakeholder analysis methodology that was developed to support stakeholder participation in water management. The methodology was implemented as a preliminary step in a stakeholder participation project in an alpine sub-catchment in Northern Italy.
