Salmon farming vulnerability to climate change in southern Chile: understanding the biophysical, socioeconomic and governance links

Submitted by NENRE Concepcion on 11 June 2019

Here we describe an assessment of climate-change vulnerability for the salmon farming sector in southern Chile using a model that combines semi-quantitative measures of Exposure (risks), Sensitivity (economic and social dependence), and Adaptation Capacity (measures that prevent and mitigate impacts).  The evaluation was carried out in 8 pilot communes representative of salmon production (marine grow-out).

Impact of Caligus Treatments on Unit Costs of Heterogenous Salmon Farms in Chile

Submitted by NENRE Concepcion on 10 June 2019

We measure the impact that sanitary treatments that control ectoparasite Caligus rogercresseyi abundance have on unit production costs of Salmo salar farms in Chile. We follow complete production cycles for a sample of farms between 2009 and 2015. We estimate a simultaneous salmon biomass growth and Caligus abundance model. The statistical analysis determines the effect of antiparasitic treatments, location of farms, environmental conditions and Caligus abundance on the salmon growth profile.

Pending Issues and Challenges of Salmon Farming in Chile: A Socioeconomic Perspective

Submitted by NENRE Concepcion on 10 June 2019

We identify and discuss the main problems and challenges in sustainable development faced by the salmon farming industry in Chile from a socio‐economic perspective. This perspective is broad, in that it includes how the industry interacts with society and the environment, but also limited, in that it only assesses the impact on different social groups and economic agents. First, we present a brief description of the structure and socio‐economic relevance of salmon farming in the country.

Co-management of small-scale fisheries and ecosystem service

Submitted by NENRE Concepcion on 9 June 2019

Marine ecosystem services are in global decline which requires new transformational changes in governance to cope with multiple anthropogenic stressors. We review the biodiversity and ecosystem services outcomes of a governance transformation towards comanagement through the allocation of territorial user rights to artisanal fisher associations (TURFs). Through a systematic review we synthesize the implications of more than 25 years of establishing a TURFs policy over ecosystem services in Chile.

Exploring Dual Discount Rates for Ecosystem Services: Evidence from a Marine Protected Area Network

Submitted by NENRE Concepcion on 9 June 2019

This paper presents a joint estimation of willingness to pay for conservation activities aimed to preserve the flow of ecosystem services provided by a marine protected area network and respondents´ personal discount rate using a contingent valuation survey. It contributes to the literature on identifying people´s discount rates moving beyond the use of the exponential schemes, to include a hyperbolic discount rate through variations in the timing and duration of the provision of public goods.

Ocean Acidification, Consumers’ preferences, and Market Adaptation Strategies in the Aquaculture Industry

Submitted by NENRE Concepcion on 9 June 2019

Ocean acidification (OA) is one of the largest emerging and significant environmental threats for the aquaculture industry, jeopardizing its role as an alternative for supporting food security. Moreover, market conditions, characterized by price volatility and low value-added products, could exacerbate the industry’s vulnerability to OA.

Implications of climate change for semi-arid dualistic agriculture: a case study in Central Chile

Submitted by NENRE Concepcion on 9 June 2019

The nexus between climate change, agriculture, and poverty has become a major topic of concern, especially for dry regions, which represent a large share of the world’s population and ecosystems vulnerable to climate change. In spite of this, to date, few studies have examined the impacts of climate change on agriculture and the adaptation strategies of vulnerable farmers from emerging semi-arid regions with dualist agriculture, in which subsistence farms coexist with commercial farms.

Interaction between crop insurance and technology adoption decisions: The case of wheat farmers in Chile

Submitted by NENRE Concepcion on 9 June 2019

This paper examines relationships between crop insurance and input technology decisions among Chilean wheat farmers. Using nationwide farm-level data, a bivariate probit model is estimated. We investigate the extent to which the adoption of production input technologies is associated with farmers’ participation in the
