Economic Economic impact of the avocado (cv. Hass) wilt disease complex in Antioquia, Colombia, crops under different technological management levels

Authors: Guillermo Ramirez-Gil, Joaquin; Gilchrist Ramelli, Elizabeth; Morales Osorio, Juan Gonzalo

The avocado wilt disease complex is the most important pathology in avocado crops worldwide. Despite its importance, research about its economic losses is limited. In this work, the objective was to determine the economic impact of the wilt disease in three regions located in Antioquia, Colombia, and its relationship with the technological level of farm management. Six nurseries and 20 fruit production lots were tested for economic losses due to the wilt disease, including all crops stages of development.

Food Carbon Literacy: A Definition and Framework Exemplified by Designing and Evaluating a Digital Grocery List for Increasing Food Carbon Literacy and Changing Behavior

Authors: Hedin, B.; Grönborg, L.; Johansson, G.

Public knowledge about the differences in greenhouse gas emissions caused by the production and transportation of different kinds of food are generally low. People with an interest in choosing food with low greenhouse gas emissions must therefore either increase this “food carbon literacy” or be provided with such information when they decide what food to buy. Research about this specific kind of food literacy is, however, scarce, lacking both well-defined terminology and interventions attempting

The economic impact of Scirtothrips perseae Nakahara (Thysanoptera : Thripidae) on California avocado production

Authors: Hoddle, M.S.; Jetter, K.M.; Morse, J.G.

In 1996, Scirtothrips perseae Nakahara (Thysanoptera: Thripidae) invaded California avocado orchards and moved pest management practices that relied almost exclusively on biological control to strategies dependent on insecticides to maintain thrips densities below economically damaging levels. By 1998, average losses due to thrips feeding damage in untreated infested groves reduced industry revenues by 12%. Producer costs increased by about 4.5% when S. perseae populations required management. In

Avocado Production and Local Trade in the Southern Highlands of Tanzania: A Case of an Emerging Trade Commodity from Horticulture

Authors: Juma, I.; Fors, H.; Hovmalm, H.P.; Nyomora, A.; Faith, M.; Geleta, M.; Carlsson, A.; Ortiz, R.O.

Avocado crop in Tanzania is sparingly investigated regardless of being an important fruit commodity. This study was undertaken to explore the yield and the value chain of this crop in the country. Data were collected mainly by face-to-face interviews with 275 avocado farmers, 231 avocado traders and 16 key informants. Descriptive statistics, Chi-square test and one-way analysis of variance were used for data analysis. The average crop yield ranged from 76 to 124 kg plant between regions. The average

Multilevel business power in environmental politics: the avocado boom and water scarcity in Chile

Authors: Madariaga, A.; Maillet, A.; Rozas, J.

The production and export of avocados in Chile have experienced explosive growth since the 1990s, severely threatening local communities' human right to water. Despite contentious activities and protest, there has been scant reaction from public authorities and policy continues to strongly support avocado exports. We explain this by analyzing the role that business plays in water politics and the different means it has to counter the search for political influence by aggrieved communities. We argue

Is smuggling welfare-improving? Evidence from avocados in Costa Rica

Authors: Metivier, J.; Bouet, A.

Does smuggling improve economic welfare? This paper provides a theoretical model of illegal trade and determines the impact of smuggling on economic welfare. We focus on Costa Rica’s recent prohibition of avocados imported from Mexico. Using unique data on trade, production, and the price of Costa Rican and Mexican avocados, we find that the quantity of avocados smuggled into Costa Rica on an annual basis ranges from 4,668 to 10,232 metric tons, representing up to four times the quantity of locally
