Climate Change Implications for Crop Production in Pacific Islands Region

The purpose of this chapter is to bring to the fore implications of climate change on the status of crop production in the Pacific Islands region. The Pacific Island people derive their livelihood or secure their food security from natural resources sectors including agriculture,forestry, fisheries and aquaculture; that is, their livelihood is depended on the environment. Any threat or impact on their environment will have profound impact on people’s livelihoods. The PICTs limited land resources are under constant pressure from many factors including climate change. Agricultural crops contribute substantially to people’s food security status.

Land degradation and sustainable land management practices in Pacific Island Countries

Land degradation in many Pacific Island Countries (PICs) has become an emerging concern in recent years. The causes of land degradation in PICs include: deforestation, inappropriate agricultural practices, overgrazing, mining, population pressure, land tenure issues and changing climate. Deforestation and inappropriate agricultural practices especially on sloping lands often lead to soil erosion, a key process leading to land degradation. On-site effects of accelerated soil erosion include decline in soil physical properties, loss of soil organic carbon and loss of plant nutrients and subsequently low crop productivity. This threatens the environment and food security for the growing population in PICs. The PICs are embarking on sustainable land management practices to address land degradation and safeguard the resource for their future generation. However, limited resources, lack of capacity and awareness on land degradation amongst the population are serious obstacles to implementation of sustainable land use plans and management.

Mapping the economic costs and benefits of Coral Triangle Initiative (CTI) and Mangrove Rehabilitation Projects (MRP) in Solomon Islands: a study of two MPAs and one MRP

This paper reports a study of costs and benefits of Coral Triangle Initiatives (CTI) and Mangrove Rehabilitation Projects (MRP) in the Solomon Islands. It was observed that the communities have different attitudes and perceptions toward climate change challenges. The different scales and magnitudes of climate change impacts that are perceived at these sites, and the different subsistence realities make them have varied responses and points of view regarding such impacts. For instance, respondents from Oibola experienced the most adverse impacts from climatic change events compared to those living in the Naro and Sairaghi sites. Introduction of CTI and MRP has driven the villagers to travel out far from their traditional fishing grounds to catch enough fish to sell and support their families. This implies higher fishing costs and time for commute. From a social perspective, this weakens the communal bond in the community. In spite of these trade-offs, the respondents expressed satisfaction with the level of benefits received from the projects, which included the rehabilitation of the ecosystems and breeding grounds for fish and habitats around the area. We mapped the costs and benefits of these projects to the villagers, and although no amounts or figures were disclosed, the benefits are compared against corresponding costs. One key factor for the success of the initiatives was the cooperation and involvement of recipient villagers, and even including the management MPAs.

A ‘Cost Barrier’ Perspective to Adaptation on a Coral Triangle Initiative (CTI) and Mangrove Rehabilitation Projects (MRP) in Solomon Islands

Mangroves are among the most fragile ecosystems in the world. At the same time, they are under considerable pressure from processes associated with climate change such as increases in temperature, salt intrusion through storm surges and sea level rise. There is a paucity of research which look at the connections between climate change and conditions of mangroves under an anthropogenic perspective. This paper reports a study of “cost as a barrier” to adaptation on a case study of Coral Triangle Initiative (CTI) and Mangrove Rehabilitation Projects (MRP) in the Solomon Islands. Questionnaires were used as instruments to obtain information from project participants to identify the cost related barriers the project participants perceived to obtain from these conservation projects. The study has identified the fact that the communities have different attitudes and perceptions toward climate change challenges. The different scales and magnitudes of climate change impacts that are perceived at the study sites, and the different subsistence realities showed that project participants have varied responses and points of view regarding such impacts. Because of this, the project participants are constrained by a set of different barriers as obstacle in their process of adapting to the new environment conservation policies at these sites. A mapping on the socio-economic costs and benefits of these projects to the villagers was performed, and identified the fact that costs of conservation programs acts as barriers to long term adaptation at these sites.

Limits and Barriers to Transformation: A Case Study of April Ridge Relocation Initiative, East Honiara, Solomon Islands

Increasing vulnerability to extreme environmental events (EEEs), exacerbated by climate change, is making adaptation inevitable for rural communities in Small Islands Developing states (SIDs), including the Pacific Island Countries and Territories (PICTs). Particularly the communities’ located along the coastal areas that are experiencing sea level rise and coastal erosions, storm surges and flooding. Governments and development agencies across the Pacific have begun to implement adaptation policies to climate change at the community level to build resilience. This paper reports what limits and barriers rural household face for long-term adaptation, using community relocation from Mataniko Riverside to April Ridge, East Honiara, Solomon Islands, as a case study. Two hundred forty six (246) families were affected by the flash flood of Mataniko Riverside in April 2014. The Solomon Island government offered flood victims plots of land in an area safe from flooding. As of July 2015, the date of the study, the relocation process had been stalled, with flood victims still waiting for the promised plots of land. Questionnaires, oral interviews and focus group discussions with flood victims identified vulnerability, flood prone area and changing weather patterns as major limits, and government failures and the socioeconomic reality of these households as major barriers to adaptation. The study determined government failures to include a complicated land tenure system, absence of infrastructure development at the new site, inconsistent commitment to ensure completion of the land transfer to the settlers, and the lack of access to credit. Socioeconomic attributes including insufficient income, lack of formal education and skills, and consequential limited livelihood alternatives, also act as crucial barriers. The research findings indicate the need to design a relocation policy that addresses the limits and barriers identified here, specifically the land tenure system, and the financial support available to facilitate the relocation process.

Transformation of rural communities: lessons from a local self-initiative for building resilience in the Solomon Islands

ABSTRACT Solomon Islands is vulnerable to negative impacts from climate change, where people’s livelihoods and their well-being are threatened, especially the viability of isolated communities. Realising the increasing risks from climate change on communities, government, in partnership with aid-donor partners, has invested millions of dollars in climate change projects, through mitigation and adaptation strategies. As a form of adaptation, the government invests in programmes aimed at increasing the adaptive capacity of the vulnerable communities through landscape and seascape projects across the rural communities. Focusing on the “transformation concept” as a long-term adaptation strategy and enlargement of climate engineering and ecological resilience concepts, the paper discusses why building resilience from transformation of rural communities, as well as from landscape and seascape projects, would benefit communities and relevant authorities. This paper describes the findings of a study on two rural villages, Keigold and Mondo, from Ranogha Islands, Western Province, in Solomon Islands, where 80% of households decided to relocate from their old village “Mondo” to their new home “Keigold” after an earthquake in 2007, as part of a self-initiative. The reallocation process can be seen as a case of pro-active community transformation that provides valuable lessons to other rural communities that may be forced to move due to impacts from natural catastrophes, including those explained by climate change risks. Lessons from this experience suggest that policy-makers and non-government organisations should consider and empower local transformation initiatives as a way to building long-term adaptation to climate change.
