3.1. Adaptation Actions to Climate Change in the C6 Project
According to The National Institute of Ecology and Climate Change [
42] and the Mexican Fund for the Conservation of the Nature [
60], the core adaptation actions to climate change implemented through the interventions made on the C6 project were: 1) management of agroecosystems and reduction of change pressures in the use of the soil through forest conservation, restoration and sustainable management, (cornfield modules with fruit trees, generation of riparian corridors); 2) Management of habitat and corridors around nature protected areas; 3) conservation of forest fragments suffering deforestation pressure; 4) livefences, restoration of soils, sustainable coffee growing and meliponiculture for the conservation; 5) interinstitutional coordination activities (networks, forums and learning communities) with different actors; 6) Installation of nurseries for endangered species and creation of nurseries networks with seed banks; 7) agroecological modules; 8) reforestation actions; and 9) Design of Action Plans for the Integrated Management of Watersheds (PAMIC) for the Tuxpan, La Antigua, Xamapa and the Gulf of Mexico basins. These actions respond to the communities' necessities to prepare the agricultural and climate systems for climate change and use the ecosystems as natural barriers to confront the extreme hydrometeorological phenomena. They also act as providers of environmental services and contribute to reducing vulnerability in climate change scenarios (increase of temperature, reduction or excess of rain and its impacts).
3.2. Contribution of the C6 Project to the SDGs and Sustainable Development
The C6 project, by its nature, contributed mainly to three SDGs: SDG 6 (clean water and sanitation), SDG 13 (climate action), and SDG 15 (Life of earth ecosystems). However, in this section, we will present the contributions of the interventions referred to other SDGs, which might be identified as additional benefits to the project and collateral contribution to the SDGs
Figure 3 shows the 29 adaptation interventions to climate change performed in the five territories. These interventions supported 14 of the 17 DSGs. There were 24 interventions to SDG 13, 20 to SDG 15, and seven to SDG 6. The collateral SDGs that received significant support were SDG 4, with 26 interventions; SDG 1, with 24; and SDG 16, with 23.
From the number of adaptation actions executed during interventions that contributed to some of the SDGs, and considering the SDGs globally in each one of its dimensions (environmental, economic, and social), the social dimension (persons) was the one with more actions support, since 41% of the total actions performed are related with the SDGs 1, SDG 2, SDG 3, SDG 4 and SDG 5 (
Figure 3). The results of the social dimension are 1.5 times superior to those of the environmental dimension (planet) and 2.5 superior to the contribution to the economic dimension (prosperity).
3.3. Identification of the SDGs and Their Impact on Sustainable Development through Interventions Performed in Each One of the Watersheds of the C6 Project
The Civil Society Organizations executed the 29 SDGs interventions performed through the C6 project in five watersheds. In general terms, the interventions supported 14 of the 17 SDGs. The project C6 objectives that did not receive support (through interventions) were SDG 9 (industry, innovations, and infrastructure), SDG 11 (cities and sustainable communities), and SDG 14 (sea life).
Figure 4 shows the contribution of the interventions in each one of the watersheds to the dimensions of sustainable development.
When comparing the dimensions of sustainable development on the five hydrological basins where interventions were performed through the C6 project, we observe that on the social dimension, the Tuxpan basin stands since it was there where the highest climate change actions (CCA) (47%) focused on social dimension were applied. This social dimension is formed by SDG 1 (end of poverty), SDG 2(zero hunger), SDG 3(Health and well-being), SDG 4(Quality education), and SDG 5 (Gender Equality). This watershed was the one that contributed with the highest number of hectares (155 Ha) of agriculture through good practices (SDG 2) and with the most significant amount of efficient technologies to reduce the contamination of close spaces through the installation of 769 wood-saving stoves (SDG 3).
Referring to the economic dimension when comparing the five watersheds, the actions performed on the Huatzuntlan-Temoloapa watershed were the ones of higher support to this dimension with a 21% total of actions contributing to the following SDGs: SDG 7 (accessible and not contaminant energy), SDG 8 (decent work and economic growth) and SDG 10 (reduction of inequalities). Referring to SDG 7, it was in this watershed where the highest quantity of biodigesters was installed (87). Within the frame of SDG 8, the highest number of honey modules were installed (59), together with the highest intercrop fruit-corn modules (38). Interestingly, this watershed was where the largest indigenous population was involved (9,957 persons).
Referring to the environmental dimension, the highest actions were executed in the La Antigua and Jamapa watersheds (31 and 32%, respectively), corresponding to SDG 6 (clean water and sanitation), SDG 12 (responsible production and consumption), SDG 13 (climate actions), and SDG 15 ( life of the earthly ecosystems). In terms of SDG 12, it was in the Jamapa watershed where most of the demonstratives' modules of agroecological coffee were installed (79 modules). In the Antigua watershed, the highest amount of organic maneuver modules was implemented (250 modules). Referred to SDG 15, the highest number of species favoring connectivity between vegetation fragments was established in the La Antigua watershed. (4,810.86 Ha).
In what refers to the peace dimension, 100% of the interventions performed in the Jamapa and Usmacinta watersheds were through actions aimed at SDG 16 (peace, justice, and solid institutions) supported by local institutions.
Regarding partnerships or alliances, the watersheds of La Antigua and Usmacinta were the ones that mainly contributed to SDG 17 (alliances to achieve the objectives). In the case of La Antigua, the alliances that supported the interventions were: 1) the Coalition of the Bioregion Organizations Jamapa and La Antigua (COBIJA), 2) The Monitoring Community Water networks, 3) melipona honey growers and beekeeping networks (Tabasco), and 4) the Biodiversity Nurseries network.
The analysis of the variance of two factors (basins and dimensions) did not find significative differences in the support percentages to the dimension of sustainable development per watershed (P=1, F=2.09E-14). Still, significant differences in the mean support percentages for sustainable development among dimensions (P = 01.096E-18, F = 47.61) were found. As regards the result of the two factors (basins and SDGs), significant differences were found in the number of interventions per watershed (P = 0,005; F = 4.80) and for each SDG (P = 2.46E-08; F = 7.49).
4. Discussion
Since the appearance of the Action Plan
To Transform Our World: 2030 Agenda for Sustainable Development, with its 169 goals and 17 Sustainable Development Objectives as an international agenda to lead countries to sustainable development [
52], the 17 SDGs have become a conceptual and a normative reference frame under which environmental, social and economic policies are designed. The SDGs are an input to the sustainable development concept [
61], through which the input to these dimensions can be visualized. In the case of the Government of Mexico in the current policy to confront climate change, both at the
Mexico National Level Determined Contribution Actualized Version 2020 (MNLDC) [
62] and the
Special Program for Climate Change 2021-2024 (SPCC) [
63] the action lines and priority objectives respectively relay to the 17 SDGs as a way to visualize the synergy between the climate and sustainable development agendas (2030 Agenda). The 27 action lines of the MNDC and the objectives of the SPCC are closely related to the 17 SDGs.
In this context, the relation between the 17 SDGs, the environmental, social, and economic dimensions of sustainable development, and the adaptation actions to climate change were executed through the C6 project interventions. Therefore, although the C6 project was conceived to support only three SDGs: SDG 6 (clean water and sanitation), SDG 13 (climate action), and SDG 15 (Life of Earthy Ecosystems), the results of this research show that the actions performed contributed to 14 SDGs. According to authors like Pérez et al. [
28], this additional support is a collateral result.
To support the relationship between the SDGs and the social and economic dimensions of sustainability, we considered what authors like Gómez-Gil [
58], Díaz-Barrado [
61], and Pérez et al. [
28] expressed: that the SDGs integrate and balance the three dimensions of sustainable development, in such manner that if a project supports the SDGs in different dimensions, then it is contributing to sustainable development.
An essential aspect of the SDGs is that their general terms give the possibility of considering an infinity of actions in each of them, adapting them as a reference frame to identify different actions in local contexts. However, this same characteristic has been criticized by those who consider the SDGs as ambiguous, rhetorical, idealists, and of short viability [
54,
58].
In terms of the C6 project, through adaptation interventions performed by the Civil Societies Organizations in the watersheds of La Antigua, Jamapa, Huatzuntlan-Temoloapa, and Usmacinta, changes in the social and natural systems of those territories were achieved to allow gaining larger adaptation capacities that enable them to reduce vulnerability to climate change. These interventions supported 14 environmental, social, and economic SDGs.
The analysis that related the intervention aspects of climate change with the SGGs showed that the interventions within the C6 project frame contributed to the DSGs in the three dimensions of sustainable development. Such identification was possible by analyzing the change factors (interventions) and the impacts on the systems (measured through indicators).
The CCA performed by the C6 project supported the SDGs in the social, economic, and environmental dimensions of sustainability. This situation can be explained by Yim [
6], who reveals that climate change's economic, social, and environmental aspects are widely interlinked with sustainable development considerations since the CCA and sustainable development share many of the objectives of reducing vulnerability. These considerations also agree with what authors like Simonet and Fatoric [
12] and Vranic and Milutinovic [
5] mention: the CCA is a tangible application of sustainable development to adopt a better quality of life. Therefore, adaptation strategies have become a practical way to achieve sustainable development.
The support for sustainable development through the execution of adaptation measures to climate change can be observed in Objective 1 of the
Special Climate Change Program 2021-2024 (SCCP) [
63], referred to: "Reduce the population, ecosystems, and biodiversity vulnerability to climate change, as well as the productive systems and the strategic infrastructure through the impulse and strengthening of the adaptation processes and increase of resilience." This situation is related to 10 of the SDGs divided into these dimensions: environmental(5), social (2), economic(1), Peace (1) and Alliances (1).
The CCA performed through the C6 project contributed more significantly to the five SDGs within the social dimension (end of poverty, zero hunger, health and well-being, quality education, and gender equality). This result could be explained because adaptation needs are related to social systems to reduce poverty and inequality, improve the conditions of life resources and sub-existence strategies, and access to education and information.
In some cases, the adaptation actions executed through the C6 project directly supported only one indicator. For instance, the indicator resilience to climate change was achieved in the case of agriculture and cattle under good practices. However, we could also consider that it impacts SDG 2 (zero hunger). In this case, it is essential to clarify that this situation indicates that this practice may add up to achieving zero hunger. Nevertheless, it may be questionable whether food security could be achieved only by promoting familiar vegetable gardens, which would aim to end poverty. This indicator exemplifies that applying different actions through the adaptation focus may help fulfill the other SDGs and, thus, the dimensions of sustainable development.
On the other hand, the CCA strategies are closely related to subjects such as social and food security, health, and education [
10]. The social sector must be considered to achieve consensus on the need and benefits of the CCA to reduce short- and long-term disasters [
64]. However, it might also be because the SDGs are more centered on social than environmental inclusion [
65]. In the case of the Tuxpan basin, which was the one that most contributed to the social dimension compared to the other basins, this may be explained by the need to improve health in the population of the high basin by using wood stoves at the same time that the pressure on the natural vegetation in the mesophile mountain woods is reduced. [
45]. On the other hand, there is also the necessity to perform better agriculture practices since rainfed agriculture, such as orange cultivation, has generated intense pressure on the basin [
45].
On the other hand, the CCAs performed within the C6 frame contributed to four of the five SDGs of the environmental dimension since physical actions were performed to 1) keep the ecosystemic services, 2) reduce the vulnerability to climate change in water scarcity situations, 3) stop the loss of biodiversity, and 4) diminish the damages caused by the frequency and seriousness of natural disasters [
10,
66,
67]. In the case of the Antigua and Jamapa basins, which contributed the most to the environmental dimension, we could explain why, in the Jamapa basin, the actions performed responded to the agricultural sector (coffee growth) [
60]. In the case of La Antigua, the performed activities respond to keep the natural coverage, favoring connectivity between vegetation fragments.
In a minor but still relevant proportion, the CCA performed within the C6 project frame contributed to the economic dimension of sustainability by contributing to three of the five SDGs in this dimension. This result is significant since a successful adaptation should help the livelihoods and the production means to be more resilient to climate change and reduce vulnerability through the sector mobility of those in poverty [
27,
68]. Besides, climate change involves different aspects of the economy and society, such as production, finances, work, consumption, and politics, to set up production changes and consumption and promote more sustainable lifestyles [
69]. Furthermore, since the population with fewer economic resources has a double inequity: poverty and climate change, the adaptation measures must be placed at the center of decisions for this population affected by inequalities [
70]. The particular case of the Huazuntlan-Temoluapa basins in the C6 project was the one that most contributed to the economic dimension compared with other basins due to the need to generate income through entrepreneurship with environmentally friendly solutions to reduce pressures on the ecosystems.
Regarding the Partnerships, more than half of the interventions were involved in some alliance to empower its action potential to confront climate change, which confirms what [
71] and Monterroso and Conde [
72] affirmed on the importance of having alliances to access information, training, share knowledge and widen the impact of the actions. These results are also explained because those actions are part of the social capital of Civil Society Organizations [
73,
74]. These organized interventions in the communities enabled them to widen their knowledge in other areas [
73], helped them to increase their adaptation capacity to climate change, and, thus, transferred them to the communities [
75,
76].
The results of this research explain the effects that Civil Society Organizations have on the communities to achieve capacities of adaptation to climate change and, at the same time, how these interventions have incidence in the natural and social systems so that they may adapt to this phenomena and also to the 17 SDGs leading towards sustainable development. As Garro-Gil [
26] indicated, the interventions performed in any territory should be studied from an open-view approach to capture all relations and effects in the whole system.
The resultant information from this research was contrasted with the Determined Contribution at the National Level (DCNL) for Mexico (2020) [
62], which refers to the adaptation component (conformed by five axes and 27 action lines). In this respect, these action lines of the adaptation component contribute to the social dimension in the following proportion: 27% to the economic, 44% to the environmental, 3% to peace, and 2% to Alliances. Thus, the DCNL contributed mainly to the environmental dimension, and the C6 project, even if it is a project that faces climate change, primarily contributed to the social dimension. It is essential to mention that the DCNL for Mexico, besides considering climate change, also promotes sustainable development, lining up both policies [
77].
According to Vranic and Milutinovic [
5], climate change adaptation and sustainable development policies are mainly performed isolated. However, as stated in the present research, it is necessary to create integrated policies that focus simultaneously on climate change and development. In this sense, the visualization of SDGs input in Mexico's climate change policy is already advanced. However, coordination between institutions to achieve the climate change policy may impact economic and social factors and environmental areas, which is really required.
Lessons learned by the C6 project will help guide new actions to increase the adaptive capacities in the communities, as stated in Article 11 of the Paris Agreement [
78]. We also have to highlight what the UNO (2020) [
67] indicates about considering all the challenges humanity has had regarding development. For instance, the recent world crisis due to the COVID-19 pandemic [
79] should prepare humanity for significant climate change crises. In this sense, the concept of human development based on nature could help to face the critical challenges of our times: to reduce the climate change impacts and adapt to it, at the same time that biodiversity is protected and human well-being is guaranteed for all persons [

5. Conclusions
The study of the interventions performed by the Civil Society Organizations within the C6 project framework in different territories from a systemic perspective enabled the identification of changes that may be achieved and how these changes help to increase the adaptative capacities that support the SDGs and have an incidence on the sustainable development of a region. Using an evaluation frame oriented to the system's general aspects contributed to understanding and relating the climate change actions performed through interventions with the indicators for each one of the SDGs.
Through the performed analysis, we could prove that the adaptation solutions to climate change applied through their C6 Project contributed not only to the SDGs considered in the project design but also to the additional or collateral SDGs in the three dimensions of sustainable development.
On average, its most outstanding input was the social dimension, followed by the environmental and economic one, considering the five hydrological watersheds of the states of Veracruz and Tabasco. Therefore, we may conclude that one way to lead to sustainable development could be through implementing actions to confront climate change, particularly adaptation.
When performing the analysis of the different intervention territories (hydrological watersheds), the one in Tuxpan contributes mainly to the social dimension, the watershed Huazuntlan-Temoloapa to the economic dimension, the ones from Jamapa and Antigua to the environmental dimension, while the La Antigua and Usumacinta to the Alliances dimension. This result has to do with the natural vocation of the usage of the soil, the natural and transformed vegetation coverage, the principal agriculture and livestock sector activities, and, in general, the characteristics of the population, as, for instance, the presence of the Indigenous population, as well as the characteristics of the Civil Society Organizations that supported the communities to implement their actions.
In future projects to support climate change, it is advisable to identify the indicators supporting each SDG to instrument the corresponding evaluations within the sustainable development framework.
