    Tropical coral reefs are amongst the most biodiverse and productive ecosystems on Earth. In recent decades, coral reefs have suffered an unprecedented decline in habitat-forming hard coral cover due to anthropogenic stressors, with severe impacts on ecosystem functioning and the provision of ecosystem services. Some of the pressing issues that coral reefs are facing can be mitigated through active reef restoration, such as coral transplantation, which aims to increase the hard coral cover, biodiversity, and structural complexity of a reef site. Studies on the passive benefits that increase the natural recovery potential and resilience of coral reefs following active restoration efforts remain scarce. In collaboration with Indo Ocean Project, this study aimed to compare benthic recruitment patterns between three coral sites located within the Nusa Penida Marine Protected Area, Indonesia. The reef sites included a restoration site with gardened Acropora corals, a natural site, and a rubble site that could serve as a restoration site. The experiment was conducted using standardized settlement tiles to measure and observe various response variables as indicators for the natural recovery potential and resilience capacity of the reef. The sites were also surveyed for their benthic reef cover, structural complexity, and fish abundance and community composition. The research objective was to find out how benthic recruitment patterns differ between restoration and natural reef sites, and why. The results confirm that active coral reef restoration efforts induce co-benefits in the benthic environment through enhanced structural complexity, leading to subsequent increases in overall fish abundance and particularly the number of herbivorous fish, and thus to a lower density of turf algae. These are promising findings for the later development of the reef site. The results do not imply that restoration efforts directly translate into enhanced coral recruitment or increases in crustose coralline algae abundance. However, the plentiful supply of spats observed at the restoration site indicates that local coral recruitment can improve over time after the transplanted corals have healed from transplantation stress and become fecund. Finally, the current rubble area can be expected to function as a restoration area in the future, as it appears to be within the reach of coral recruits. This study demonstrates that active coral reef restoration can yield benefits for the whole benthic ecosystem, and thereby aid recovery and strengthen resilience at localized scales. Given the accelerated rate of coral reef degradation, regular monitoring of restoration success is crucial to avoid loss of information regarding the benefits of active coral reef restoration for the fragile benthic ecosystem.

    In this thesis I focus on a novel disaster response and preparedness mechanism called forecast-based financing. The mechanism is linked to the changing paradigm of humanitarian response that calls for more localized and more resilience building solutions to addressing and preventing humanitarian crisis. It is also in the core of the anticipation agenda which argues that waiting for disasters to happen is not a sustainable option and that forecast data and pre-agreed triggers and actions should be used in order to prevent both loss of lives and mitigate the cost and impact of disasters. Main hypothesis is that climate related hazards to livelihoods and food security seems to be the sector where forecast-based financing could have most potential for increasing resilience and sustainability. Slow onset crises with long lead-time allow for better targeting and more variety of actions. As the lifetime of the action is longer, there is less chance of action which is in vain. Furthermore, the actions which are more localized, for example direct support to farmers, can decrease their vulnerabilities. I aim at taking a critical approach to assessing this potentiality associated with the forecast-based financing mechanism through case study. The three cases (Mongolia, Kenya, Zimbabwe) were selected from pilots implemented by the main actors: the Red Cross, World Food Programme (WFP) and Food and Agriculture Organization (FAO) and Start Network. This thesis uses a combination of evaluative and heuristic approach to qualitative case study analysis. To answer the first research question, 1) is the forecast-based financing mechanism successful in prioritization of actions in a way that best address the needs and resources of vulnerable populations, I aim at finding out if mechanism is effective (or potentially effective) in delivering impact. For the second research question, 2) are the actions sustainable and do they bring socio-economic benefits that go beyond meeting acute humanitarian needs, I will see if new pathways are found for confirming the defined hypothesis. I am using heuristic approach in terms of finding new links e.g. between actions and needs of either donors, actors or beneficiaries. I asses and analyse available reports and evaluations (secondary data) of the selected operations. I conducted eleven (11) semi-structured key informant interviews (primary data) using practitioner’s perspective for retrieving qualitative data, for further understanding and for triangulation. All key informants were affiliated to the cases. My analysis show that the potentiality for development impacts and long-term transformation of the forecast-based financing is there but it is not utilized in the cases reviewed nor is it perceived in a same way across practitioners of different backgrounds. Currently the mechanism is used more for effective response, not for addressing the root causes of vulnerability. In general, the entitlement or empowering of a person who is affected by disaster currently does not go beyond securing bridge over lean season, avoiding negative coping mechanisms or e.g. better yield or survival of livestock. Sustainability potential of the forecast-based financing seems to be currently underutilized and international funding envelopes do not offer an alternative to the humanitarian funding launched case-by-case. Most of the practitioners interviewed were clearly in favour of linking and using forecast-based financing in some way to long-term programming, thinking outside of the framework of humanitarian response, extending lead time significantly and adding positive reinforcement inputs. I argue that with a lead time that goes long in advance, towards development actions, the mechanism needs to be reframed for the donors and the sources of funding might need to be reconsidered. To implement meaningful resilience actions in slow onset cases, triggers need to be early enough and actions in two phases: 1) anticipatory and benefiting from forecast and 2) early response. At beneficiary level the actions should be geared up to better address underlying socio-economic vulnerabilities and take advantage of the long lead time.

    We have not succeeded to halt biodiversity loss despite international agreements. Conserving ecological connectivity is crucial when conserving biodiversity in the long run. This thesis studies policy instruments that promote ecological connectivity and conserve ecological processes. The aim of this study is to find out how Finnish environmental policy should be developed in order to promote ecological connectivity and biodiversity conservation. The research questions are: 1) How current nature conservation policy instruments promote ecological connectivity? 2) How policy instruments could promote ecological connectivity better? 3) Could green infrastructure approach help to conserve biodiversity? Ecological connectivity affects the biodiversity especially trough species dispersal. The environment is governed by different policy instruments, which have various effects on ecological connectivity. The green infrastructure is a new policy approach that underlines holistic planning. The green infrastructure is ecologically connected network of green and blue spaces that produces ecosystem services. The data comes from a SCALES project survey on Securing the Conservation of Biodiversity Across Administrative Levels and Spatial, Ecological and Temporal Scales. A link to the web-based questionnaire was sent to 214 Finnish experts of ecological connectivity and 47 persons answered to the questions. The data was analysed quantitatively and qualitatively. The main analysis methods were repeated measures ANOVA and cluster analysis. Content analysis was done from qualitative data. The experts thought that ecological connectivity is more important than the current consideration shows. The policy instruments that promote ecological connectivity in the best way are the instruments, which have a wide spatial cover and urban and small-scale instruments are considered worse. The potential of policy instruments to promote ecological connectivity is higher than the current implementation demonstrates. The integration of biodiversity conservation to the other sector policies is considered important. Nature conservation was thought to be more important aspect than ecosystem services in implementation of green infrastructure. The respondent believed that green infrastructure has could have potential of enhancing nature conservation.

    Food security is increasingly threatened in agrarian societies as environmental change has disrupted traditional food systems around the world, thus robbing the affected communities of their rights to food sovereignty. This thesis seeks to examine the role of traditional Indigenous (agri)cultural heritage maintenance in the present day, especially as impacted by climate change and land degradation. Using the case of Hek’o:we – or “waffle gardening” – in the Zuni Pueblo (known also as the Middle Place), the study aims to illuminate the benefits of youth-oriented education for the protection of food sovereignty, the continuance of ancestral knowledge, and the conservation of the land and natural resources. Existing literature was reviewed to evaluate the need for this research, as well as to illuminate the place of this study in the broad literature base of related topics in Western academia. The resulting literature review was compiled to serve also as a theoretical framework for narrowing down three key contexts in which this case study could be examined: 1. The history, development, and use of Hek’o:we, as understood currently in Western academia; 2. Indigenous food sovereignty; and 3. The role of youth education in the (re)production of agricultural knowledge. Much of the earlier research regarding Zuni (agri)cultural heritage maintenance and Hek’o:we agriculture has been conducted without considering the needs of the Zuni community. Thus, significant ethical considerations were central to the development of this study, including the goal of amplifying Zuni voices in the dissemination of the research results. Data collection was conducted over video chat; in a recorded group interview, organizers from the Zuni Youth Enrichment Project’s Food Sovereignty team shared stories and insight about the topics at hand. The results are presented primarily in the words of the participants. Three main topics emerged: Hek’o:we and community-wide resilience; intergenerational education that en-gages the whole family; and land-based considerations including climate change, water scarcity, and the overall notion of living with the land. Conclusions posit that traditional agricultural practices are promoting resilience, engagement with ancestral knowledge, conservation of the land and water, and many other ob-servable benefits. Climate change and land degradation, caused by intentional actions by the settler state, may pose threats to food sovereignty and the health of Zuni people, but the community is able to find strength in the practices developed by their ancestors.
