Abstract

Although the concurrent impacts of pollution and climate change on livelihoods of fishermen are well established, the mechanics within the livelihoods are less known. To understand the mechanics, this paper evaluates the responses of fishermen on the impact of pollution and climate change on livelihoods, using field surveys of 124 fishermen. The result indicated that plastic and domestic wastes are the major lagoon pollutants identified by the respondents. Also, almost all the respondents noted that climate change and lagoon pollution impact negatively on the lagoon which subsequently affect their fishing activities. The fishermen reported difficulty in meeting basic livelihood essentials including feeding their family, paying of their children school expenses, paying of hospital and utility bills. The analysis of logistic model indicated that the likelihood of fishermen landing a high volume of fish catch was statistically significantly influenced by the number of days of fishing in a week, lagoon water temperature, other jobs and formal education. Considering the fact that the main factors impacting on fishing activities are extrinsic without controls of the fishermen, there is need for policy makers within the Cape Coast Metropolis to address drainage systems that feed pollutants into the lagoon.

Abstract

Climate change has negative consequences for the biophysical environment and an observable impact on flows of ecosystem services. Considering the high relevance of ecosystem services, it is imperative to analyze the present status of ecosystem services flows, for effective planning to cope with natural and anthropogenic catastrophes. It is equally important to identify drivers of natural resource deterioration. In a study conducted among 545 randomly selected households in 91 villages along an altitudinal gradient (1801 m asl (zone C)) in Pauri District, Uttarakhand, India, a multi-disciplinary bottom-up, indicator-based approach was applied for identification and normalization of indicators pertaining to ecosystem services. The greatest reduction in ecosystem services was recorded in zone A (0.56), followed by zone B (0.46) and C (0.35). The greatest estimated deterioration was seen in supportive (0.48) and regulatory (0.47) services. The perspective provided can facilitate adaptive management of ecosystems along an altitudinal gradient in the Himalayas, e.g., the district-level quantification of ecosystem services can guide policy-makers and planners towards more efficient adaptation planning and help minimize the gap between local requirements and policy/program formulation.
