The Impact

Honey bees and the pollination services they provide are fundamental for agriculture and biodiversity. Agrochemical products and other classes of contaminants, such as trace elements and polycyclic aromatic hydrocarbons, contribute to the general decline of bees’ populations. For this reason, effects, and particularly sublethal effects of contaminants need to be investigated. We conducted a review of the existing literature regarding the type of effects evaluated in Apis mellifera, collecting information about regions, methodological approaches, the type of contaminants, and honey bees’ life stages. Europe and North America are the regions in which A. mellifera biological responses were mostly studied and the most investigated compounds are insecticides. A. mellifera was studied more in the laboratory than in field conditions. Through the observation of the different responses examined, we found that there were several knowledge gaps that should be addressed, particularly within enzymatic and molecular responses, such as those regarding the immune system and genotoxicity. The importance of developing an integrated approach that combines responses at different levels, from molecular to organism and population, needs to be highlighted in order to evaluate the impact of anthropogenic contamination on this pollinator species.

The Impact

Ecosystem services (ES) such as pollination are vital for the continuous supply of food to a growing human population, but the decline in populations of insect pollinators worldwide poses a threat to food and nutritional security. Using a pollinator (honeybee) exclusion approach, we evaluated the impact of pollinator scarcity on production in four brassica fields, two producing hybrid seeds and two producing open-pollinated ones. There was a clear reduction in seed yield as pollination rates declined. Open-pollinated crops produced significantly higher yields than did the hybrid ones at all pollination rates. The hybrid crops required at least 0.50 of background pollination rates to achieve maximum yield, whereas in open-pollinated crops, 0.25 pollination rates were necessary for maximum yield. The total estimated economic value of pollination services provided by honeybees to the agricultural industry in New Zealand is NZD $1.96 billion annually. This study indicates that loss of pollination services can result in significant declines in production and have serious implications for the market economy in New Zealand. Depending on the extent of honeybee population decline, and assuming that results in declining pollination services, the estimated economic loss to New Zealand agriculture could be in the range of NZD $295–728 million annually.

Total Economic Value

Wild and managed bees provide pollination services to crops and wild plants, as well as a variety of other services beneficial to humans. Honey bees are the most economically valuable pollinator worldwide. It has been calculated that 9.5% of the total economic value of agricultural production comes from insect pollination, thus amounting to just under USD 200 billion globally. More than 100 important crops depend on pollination by honey bees. The latter pollinate not only a wide number of commercial crops but also many wild plants, some of which are threatened by extinction and constitute a valuable genetic resource. Moreover, as pollinators, honey bees play a significant role in every aspect of the ecosystem by facilitating the growth of trees, flowers, and other plants that serve as food and shelter for many large and small creatures. In this paper, we describe how the reduction in honey bee populations affects various economic sectors, as well as human health.

Abstract The most important ecosystem service for sustainable crop production is pollination, the mutualistic interaction between plants and animals. Honeybees are being indispensable role in this process. The total economic value of crop pollination worldwide has been estimated at €153 billion annually. Animal pollination of agricultural crops is provided by both managed and wild pollinators. The aim of this study was to determine the economic value of pollination services and vulnerability of Ethiopian agriculture in the face of pollinator decline. An improved approach to determine the economic value of pollination (EVP) services is applied to multiply a crop’s total value by a coefficient between zero and one representing the crop’s dependency on pollination services for production. The potential production value loss due to lack of pollinators is also computed as the ratio of EVP to economic production value. Then EVP was $ 815.2 million dollars and vulnerability of Ethiopian agriculture due to lack of pollinators 16% in the 2015/16 crop production season. The regional state of Oromia benefited the most followed by the regional states of Amhara and South Nation Nationality People (SNPP). Coffee, the leading crop, has the highest EVP in the country followed by Faba beans and Nug (Guizotia abyssinica). Ethiopia has highly benefited from biological pollinators, so protecting them has significant role in the country’s economy. Most crops in Ethiopia have no pollination dependency ratio and some minor crop has no production data, incorporating them possible to better estimation of EVP service for the future.

Coffee Farm

On-farm pollination experiments were conducted in 30 different small-scale coffee fields to determine monetary value attributable to pollination services in coffee production and to identify the degree of influences of various socio-ecological drivers in Uganda. Ecological-economic approaches were applied to determine the economic value of pollinating services. Economic value of bees increased significantly with increase in coffee farm size, bee diversity, and cover of seminatural habitats. The value of bees declined sharply (P<0.05) with forest distance and cultivation intensity. Economic values of pollinating services associated with coffee fields established in regions with low intensity were found to be high. Organically managed small-scale coffee fields were 2 times more profitable than commercially managed farms. The annual value of pollinating services delivered by wild bees oscillated between US$67.18 and US$1431.36. Central Uganda produces in total 0.401 million tons of coffee beans for an approximate economic value of US$214 million from which US$149.42 million are attributable to pollination services. Policy makers should strengthen environmental/agricultural extension service systems to better serve farmers. Farmers are recommended to protect/increase the cover of natural and semi-natural habitats in the vicinity of their coffee fields to receive high economic benefits from pollinating services delivered by bees.

Abstract Using a production function approach, we estimate that the economic value of biotic pollination to Georgia’s agriculture increased from $425 million in 2009 to $488 million in 2017 in real terms. We perform spatial analysis to reveal county-level spatial patterns and temporal trends in that value. Using a unique set of pollinator survey data, we also compare the locations of biotic pollinators to the areas they bring the most economic value to, which provides insights on the variation in the dependency of the crop mix to pollination services.

Pollinating Insects

Scientific studies state that a considerable part of the economic value of crop plant production should be attributed to the free services of pollinating insects. Such calculations are available for several EU and North American countries, and the present paper evaluates the value of pollination services to 19 important Polish crop plants. It is estimated that the market value of 19 entomogamous crops reaches the sum of approx. 7.5 billion PLN (thousand million) (approx. 1.8 billion EUR), 39% of this may be attributed to the insect activities, the most important being bees (the service value of approx. 2.5 billion PLN/0.6 billion EUR) and dipterans (almost 0.3 billion PLN/ 74 billion EUR). The paper discusses also the challenges and pitfalls of similar estimations and the need for conservation actions directed on crop plant pollinators.

Abstract This paper estimates the economic value of ecosystem services provided by Brazilian native bee, Xylocopa spp. Latreille (Hymenoptera: Apidae), pollination on a scale relevant to individual smallholder farmers that produce yellow passion fruit (Passiflora edulis Sims). The study areas are located in the vicinity of Pedro de Toledo and Itariri (Sao Paulo State—Brazil), in the Atlantic Forest region. The local economy is based on family farms, small stores, and ecotourism. The value was obtained using the ecological economics Avoided Cost Method, also known as replacement cost. Farms from this region informally hire temporary day laborers to supplement natural pollination with manual pollination of passion fruit flowers, so the cost of contracting temporary laborers was used to estimate the economic value of bee pollination. The value of pollination services was estimated at US$ 2,583.00 per hectare over 2 yr of P. edulis farming. Our estimates based on passion fruit farmer surveys and ecological valuation over 2 yr suggest that manual pollination accounts for 44–48% of production costs and results in a loss of ~58% of profits when wild bee pollination services are not available and manual pollination is required. We suggest that smallholder farmers follow the suggestions of previous studies and conserve adequate forest habitat for bee nesting and foraging, plan pesticide use around flowering and pollination, and supplement bee populations to maximize the benefit of the pollination ecosystem service and profits.
