Coexistence of Fisheries with River Dolphin Conservation

Abstract: Freshwater biodiversity conservation is generally perceived to conflict with human use and extraction (e.g., fisheries). Overexploited fisheries upset the balance between local economic needs and endangered species’ conservation. We investigated resource competition between fisheries and Ganges river dolphins (Platanista gangetica gangetica) in a human‐dominated river system in India to assess the potential for their coexistence. We surveyed a 65‐km stretch of the lower Ganga River to assess habitat use by dolphins (encounter rates) and fishing activity (habitat preferences of fishers, intensity of net and boat use). Dolphin abundance in the main channel increased from 179 (SE 7) (mid dry season) to 270 (SE 8) (peak dry season), probably as a result of immigration from upstream tributaries. Dolphins preferred river channels with muddy, rocky substrates, and deep midchannel waters. These areas overlapped considerably with fishing areas. Sites with 2–6 boats/km (moderately fished) were more preferred by dolphins than sites with 8–55 boats/km (heavily fished). Estimated spatial (85%) and prey–resource overlap (75%) between fisheries and dolphins (chiefly predators of small fish) suggests a high level of competition between the two groups. A decrease in abundance of larger fish, indicated by the fact that small fish comprised 74% of the total caught, may have intensified the present competition. Dolphins seem resilient to changes in fish community structure and may persist in overfished rivers. Regulated fishing in dolphin hotspots and maintenance of adequate dry season flows can sustain dolphins in tributaries and reduce competition in the main river. Fish‐stock restoration and management, effective monitoring, curbing destructive fishing practices, secure tenure rights, and provision of alternative livelihoods for fishers may help reconcile conservation and local needs in overexploited river systems.     

A Critical Analysis of Forest Policies of Pakistan: Implications for Sustainable Livelihoods

Pakistan has very low forest cover, but these forests are very diverse in nature and of significant importance for the livelihood security of millions of rural people who live in and around these forests. Policies, institutions and processes form the context within which individuals and households construct and adapt livelihood strategies, on the other hand these institutionally shaped livelihood strategies may have an impact on the sustainability of natural resource use. The present paper aims to critically analyse the forest policies of Pakistan. Implications for sustainable forest management and livelihood security of forest dependent people are also given. The first forest policy of Pakistan was announced in 1955 followed by the forest policies of 1962, 1975, 1980, 1988 as part of the National Agricultural Policy, 1991, and the latest in 2001. Most of the forest policies were associated with the change of government. There was much rhetoric in some recent policies regarding the concept of “participation” and “sustainable livelihoods” but in practice these policies are also replica of the previously top-down, autocratic and non-participatory forest policies. Pakistan needs to develop a sustainable, workable, research-based, and people-friendly forest policy enable to catering to the changing needs of stakeholders including government.     

Responding to security threats: livelihoods under protracted conflict in Sri Lanka

Populations affected by violent conflicts often withstand threats to their security as well as threats to their livelihoods. Their response to the former threats nontrivially affects their response to the latter threats, and vice versa. This paper examines the interplay between protection and livelihood strategies using a sample of households selected from the Anuradhapura district of Sri Lanka. The fieldwork for this study was completed in 2008, producing evidence that the protection and livelihood strategies employed by households affected by the protracted conflict in Sri Lanka are interlaced. In addition, the research discovered that Muslim and Sinhalese households largely responded to the protracted conflict in ways that are unique to their ethnic group. Certain vulnerabilities that impinge on protection and certain opportunities that support livelihoods are shown to be ethnicised. Hence, the final livelihood outcome, which is defined narrowly here as the household's income, also appears to be ethnicised.     

Recovering from disasters: a study of livelihoods in post‐quake villages in northern Pakistan

The October 2005 earthquake in northern Pakistan severely affected the livelihoods of 1.5 million people. With the destruction of material assets and communications infrastructure, the quake had a devastating impact on people's way of life in this remote mountainous region. This paper explores livelihood revival interventions undertaken during the earthquake response, and considers how differentiated livelihood outcomes were achieved. In addressing this objective the paper examines livelihood rehabilitation schemes in terms of structural aspects, working strategies, key factors, strengths of interventions and the role of human agency in influencing livelihood trajectories of quake‐affected communities. Primary data for this study was gathered in northern Pakistan between October 2008 and January 2009. The study identifies structural shortcomings and strengths of the programmes attempting to revive the livelihoods of poor and vulnerable households. It identifies how households in two villages made the most of opportunities to improve their lives and move towards favourable outcomes.     

Resource users as land-sea links in coastal and marine socioecological systems

Coastal zones, which connect terrestrial and aquatic ecosystems, are among the most resource-rich regions globally and home to nearly 40% of the global human population. Because human land-based activities can alter natural processes in ways that affect adjacent aquatic ecosystems, land-sea interactions are increasingly recognized as critical to coastal conservation planning and governance. However, the complex socioeconomic dynamics inherent in coastal and marine socioecological systems (SESs) have received little consideration. Drawing on knowledge generalized from long-term studies in Caribbean Nicaragua, we devised a conceptual framework that clarifies the multiple ways socioeconomically driven behavior can link the land and sea. In addition to other ecosystem effects, the framework illustrates how feedbacks resulting from changes to aquatic resources can influence terrestrial resource management decisions and land uses. We assessed the framework by applying it to empirical studies from a variety of coastal SESs. The results suggest its broad applicability and highlighted the paucity of research that explicitly investigates the effects of human behavior on coastal SES dynamics. We encourage researchers and policy makers to consider direct, indirect, and bidirectional cross-ecosystem links that move beyond traditionally recognized land-to-sea processes.
