Under an ecosystem approach, efforts seek to improve the livelihoods and resilience of ecosystems in order to reduce the vulnerability of local communities to the challenges of erratic rains, changing pf seasons, storms and consequent loss of crops. The EbA measures promoted are:

• Restoration of riverbank forests to prevent river bank erosion during extreme storms and flash floods. This is promoted with annual Binational Reforestation Days and guided by a Restoration Opportunities study in river banks. 
• Agrodiversification was undertaken with local farmers to increase the number and varieties of crop species, fruit and wood trees in their plots, while combining with animals. This aim to improve the resilience of the system against erratic rainfall and changing seasonal patterns. The model is locally named as "integral farms".
• Learning and exchange through a network of resilient farmers with knowledge on EbA.
• Organization of agrobiodiversity fairs for the promotion and rescue of endemic seeds.

The model used a "learning by doing" approach and the adoption of iterative decisions that identify short-term strategies in light of long-term uncertainties. Learning and evaluation allows new information to be considered and inform policies at different levels. 

The EbA measures implemented in the sub-basin focused on water and soil ecosystem services, on productive diversification and on mitigating the impacts of climate change on crops and community assets. Together with >100 producers from the upper part of the sub-basin, fruit and timber trees were introduced into agroforestry systems bordering 7 water sources, and organic agriculture was encouraged, allowing families to diversify their income and reduce the vulnerability of their crops, productive infrastructure and housing, which are affected by strong winds. This, in combination with soil and water conservation practices (hillside irrigation ditches, non-burning and crop residue incorporation), has helped to reduce soil erosion caused by extreme rainfall, as well as improved moisture retention in crops, soil fertility, and water infiltration and capture in the area. The EbA measures not only generate more resilient agro-ecosystems, but also increase the availability of water, which benefits >400 families in the sub-basin. These actions have raised awareness of the need for ecosystem and adaptive approaches to territorial management in the face of climate change.

Supporting producers to implement EbA measures that improve their productive practices and increase the resilience of agro-ecosystems, generates an "action learning" process that allows other actors to witness the benefits of these measures and creates conditions for their sustainability and up-scaling.

• The socio-environmental vulnerability of communities and their livelihoods is examined, in a participatory way, in order to then prioritize EbA measures and their location.
• Technical support is provided to producers, complemented with their traditional knowledge, to plan and implement the EbA measures (improvements to agroforestry systems).
• Training and exchanges of experience are carried out on transboundary cooperation; integrated management of water resources; AbE; policy frameworks and legislation on water and climate change; and policy influencing and communication.
• Monitoring of food and water security is carried out with 14 families.
• The governance and management capacities of community and municipal entities linked to water resource management is strengthened.

The increase in skills and knowledge strengthens social capital and contributes to community empowerment and to valuing ecosystem services and their management for the benefit of all.

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.

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.

After analysing vulnerabilities and adaptation establishing priorities, the ejido La Azteca and ejido Alpujarras sought to protect the ecosystem services provided by their forests (water capture, biodiversity, soil and fertility structure) aiming to benefit their livelohoods and resilience to climate change.

The following EbA measures and actions were implemented to face heavy rains, storms, erosion and to improve ecosystem resilience, soil water retention and water downstream. 

1. Protection and restoration of the cloud forest in the Tacaná Volcano Reserve. Specific actions were: 

• natural regeneration of forest degraded areas

• reforestation with native species

• wildfire preventative measures such as firebreaks

• soil conservation practices
• surveillance to prevent illegal logging, illegal hunting and extraction of flora and fauna, forest fires, and to detect outbreaks of pests

2. Optimization of agroforestry systems,: 

• Soil conservation practices (e.g. live fences, terraces and breakwater small natural constructions). Live fences use plant species to divide plots, provide shade and protect againts erosion.
• introducing forest and fruit species into coffee plantations (shade-grown).

Measures helped to improve and maintain the resilience and integrity of the natural forest.

An "action learning" approach consisted of training and supporting communities to implement EbA measures. 

• A socio-environmental vulnerability assessment of 2 ejidos (211 families) was carried out in a participatory manner to identify and prioritize EbA measures.
• Technical support is provided complementing families' traditional knowledge, to ensure that EbA measures contribute to food and water security.
• Exchanges and trainings are organized for producers, ejido authorities and municipalities on climate change, food security, sustainable forest management and soil conservation.

Furthermore, the solution focused on generating evidence on the benefits of EbA measures on water and food security:

• In collaboration with IUCN and the International Center for Tropical Agriculture (CIAT) household surveys were carried out to study the benefits of the EbA measures or food security.  The joint methodology was also applied in five other countries.
• A methodology to understand the effectiveness of EbA on water security was developed and was applied in La Azteca and Alpujarras. The methods include: interviews, focus groups and environmental  data collection in the field (e.g. water quality).

The ejido Conquista Campesina wanted to restore mangrove forests and the ecosystem services that these provide (biological diversity, water quality, protection against storms) with a view to strengthening its food security and resilience in the face of climate change.

The opening of hydrological channels was first carried out to replenish with water areas damaged by sedimentation; then the collection, translocation and sowing of propagules in the degraded areas was coordinated. Through the ‘payment of laboured days’ as restoration incentives (Payment for Environmental Services), these efforts also achieved economic benefits for the community. While the water open surface was improved in fishing areas, the community was also protecting itself against winds and storm surges in areas used for collecting, fishing and housing. In addition, family gardens (orchards), agroforestry and apiculture were implemented in some plots to diversify the products used by families for self-consumption. These processes provided important means of learning for ejido members, both men and women, who acquired technical knowledge (on mangrove restoration and managing plants in association) and a better understanding of the relationship between climate change, conservation and food security.

Supporting ejido community members to implement EbA measures generates a process of "action learning" that, in addition to teaching, aims to generate evidence on the benefits of EbA and create conditions for their sustainability and up-scaling.

• CRiSTAL Community Risk Assessment
• Mangrove restoration (4.1 ha) and surveillance are considered priority EbA measures.
• Technical support is provided to 33 community members (men and women), complemented with their traditional knowledge, to learn about mangrove restoration techniques and carry out the restoration of degraded areas.
• 5 community technicians are trained to monitor and evaluate the restored areas (measurements of tree diameter, physical-chemical parameters and sediments).
• Monitoring and evaluation is carried out to learn about the food security with 10 families (sample) and study the benefits of restoration on livelihoods on dry and rainy season. Household social surveys used as methodology (guidelines to be published).
• Joint learning on the advantages of income diversification, such as gardens (orchards), agroforestry and beekeeping.

The increase in capacities and knowledge strengthens human capital and contributes to community empowerment and with that, to more possibilities for political advocacy and accessing financial resources.

Dredging, recognized as a serious threat to the marine turtles, was identified by IUCN as a priority.  IUCN, with experts from the Species Survival Commission’s Marine Turtle Specialist Group designed and developed a dredging protocol to be followed during port operations. These included installing turtle deflectors on all dredger drag-heads to help ensure turtles were not pulled into the dredger. Trained observers were assigned to all dredgers to monitor this process. These observers would check screens on inflow and overflow pipes on a 24/7 basis. These measures (deflectors, screens, and human observers) were put in place to ensure that the dredging was “turtle friendly”. Such measures were the first to have been put in place in the history of dredging activities in India.

Lighting was the second major threat identified because excess glare is known to distract turtle hatchlings as they instinctively move towards brightly lit areas and away from the sea. For this, the IUCN Commission experts provided specific guidelines for the port’s lighting plan, which was adopted by the port authorities. IUCN further supported Tata Steel in identifying the right design for these lights. Today, Dhamra Port is the first and only port in India to have installed “turtle friendly” lighting.
