Governance for adaptation in the shared basin of the Goascorán River

The work in Goascorán targeted several levels of decision-making to reinforce the basin’s governance through the vertical and horizontal articulation of socio-political platforms; all of this in order to achieve a multidimensional (multilevel and multisectoral) governance model for adaptation. At the community level, EbA measures were implemented in the field to improve food and water security. With municipalities, adaptation to climate change was incorporated into Environmental and Municipal Development Plans. At the micro-basin level, two Micro-basin Committees (one on each side of the border) were created as multi-stakeholder governance platforms, receiving training, preparing internal regulations and plans, and enabling wide-ranging advocacy (e.g. civil society, municipalities and municipal commonwealths). At the basin level, in El Salvador, where several Technical Tables operate, two Environmental Technical Tables were established for the north and south of La Union in order to articulate the basin’s shared management, and linkages were sought with the Goascorán River Basin Council that operates on the Honduran side. At the national level, the recent National Adaptation Plan of Honduras comprises the EbA approach, as does the new Regulation of the Honduran Climate Change Law

The participation of all basin stakeholders has been at the core of the conformation and training of new governance structures for the Lituy (Honduras) and Honduritas (El Salvador) microbasins. The integration of grassroots (community-based) organizations, such as water boards, producer associations, women's or youth groups, Community Development Associations and educational centers, has been important. Locally, the leadership shown by teachers, women and community authorities contributed significantly to social mobilization and the adoption and scaling-up of EbA measures, making these actors an essential part of the "learning by doing" processes of communities. The result is self-motivated communities that participate and take on responsibilities. At the basin level, the Goascorán River Basin Council on the Honduran side was expanded, while in El Salvador, the most appropriate figure to accommodate the broad membership required was the Environmental Technical Table, which is why two Tables (for the northern and southern areas of La Union) were created and strengthened. Many of the members have become advocates for the work of the Tables with the aim to have these structures recognized by local authorities and legalized in the medium term.

Adaptation to climate change is immersed in a series of uncertainties regarding future climate impacts and development trajectories. Therefore, adaptation must proceed under a flexible “learning by doing" approach, integrating flexibility into legal and policy frameworks, and into sequential and iterative decisions that generate short-term strategies in view of the long-term uncertainties. In Goascorán, the lack of regulatory and policy frameworks for the management of shared basins limits the capacity to jointly respond to climate change - and therefore to be flexible and learn. This limitation was remedied by integrating adaptation into various management instruments at the micro-watershed, municipal and national level, and in transboundary agendas between local actors. The effectiveness of these (and other new) frameworks should be evaluated in interim periods, to allow for revisions and adjustments as knowledge about climate change increases; the same is true for EbA measures in the short term. The information that underpins these iterative processes must integrate Western science with local knowledge. In this way, it is possible to be flexible and identify new adaptation options and criteria for its evaluation.

Governance for adaptation requires an ecosystemic vision, whereby actions implemented in the field for building up the resilience of natural resources focus more on protecting watershed ecosystem services (forest-water-soil) and less on responding only to problems found at the level of individual farms. For this reason, the prioritization of restoration areas is key, since it must be with a view to improving water capture and also productivity (local livelihoods). The three types of EbA measures implemented in the Goascorán River basin were: 1) restoration of water sources, 2) soil conservation, and 3) agroforestry systems. This combination recognizes the interdependence of the forest-water-soil components and allows communities to witness positive changes over intermediate periods, which in turn increases their confidence in the "natural solutions" being introduced for water and food security. Territorial management with a basin or micro-basin vision also contributes to the ecosystem approach that is required for sustainable development, that is, one that is adaptive to climate change.
