“…11 Currently, there is global loss of pollination services resulted in a $302 billion reduction in the value of production across all sectors and regions representing a 0.39% decrease from the 2004 baseline. 12 This was due to human induced impacts such as habitat destruction, land use change, use of chemicals (pesticides and herbicides), climate change, and invasive species. 3,13 These also induce a reduction of both the number and species of native insect pollinators of crops and wild plants.…”

Pollination and pollinators provide important ecosystem service for human well being. Identifying and managing diversity of pollinators in Ethiopia have significant effect on the conservation and improvement of agricultural yield in terms of quality and quantity on farms. Thus, improvement of yield needs understanding of farmers' perceptions and knowledge on pollination services and the importance of insect pollinators' for agricultural production among other key production and management factors considered. Therefore, the aim of this study was to investigate and document farmers' perception on the importance of insect pollinators, their current status, distributions and farmers' knowledge of the role of insect pollinators in a farmland habitat of the area. Transect sampling, household surveys of 131 house hold heads, focus group discussion, and direct field observation method was used to collect data. The result showed that most farmers 94 (77%) had no knowledge on pollination and the importance of insect pollinators. In addition more than half 76 (62.3%) revealed that they did not know insect pollinators except honeybee. There is also significant difference in their views. Eighty three (68%) of the respondents could not identify the role of honeybees and other insect pollinators in agricultural seed set with a significant differences. More than half of the respondents 76 (62.3%) were unaware that insect pollinators feed or drink from the plants. Education, knowledge on pollen and/or nectar, and source of information significantly affected knowledge of farmers about pollination and the importance of insect pollinators. However, more than half of the respondents 75 (61.5%) revealed that they have knowledge of the impact of agricultural input (insecticides and herbicides) on insect pollinators' activity. Most farmers 103 (84.4%) thought that insect pollinators population show a declining trend from year to year and 78.7% perceived that the trend was due to spray of herbicides and insecticides, coupled with drought and deforestation. The study revealed that most of the farmers lack knowledge of pollination and the importance of insect pollinator in agriculture production. Therefore, awareness creation on the importance of pollinators and pollination is urgently needed for the farmers to conserve pollinators.

“…The concerns raised are certainly justifiable. The global pollination industry has suffered estimated losses of more than $100 billion in recent years (Bauer and Wing 2016), and neonicotinoids have been linked to losses in several non-pollinator organisms. But most of existing research has focused singularly on the negative consequences of neonicotinoid use, without considering the bigger picture of realized impacts from widespread NeoST adoption.…”

This study exploits a novel dataset containing more than 89,000 farm-level surveys over a 17-year period to investigate how neonicotinoid seed treatments in maize, now ubiquitous, have affected the use of other insecticides. Neonicotinoid insecticides are the most used class of insecticides in the world, but they are controversial because of their high toxicity to honeybees. In the United States, maize production accounts for the majority of neonicotinoid use, mostly as seed treatments. We find that neonicotinoids substituted for other major insecticides: plots planted with neonicotinoidtreated seeds were 52% and 47% less likely to be treated with a pyrethroid and organophosphate insecticide, respectively. Although honeybees have been put at greater risk by neonicotinoids, the changed pattern of pest control instruments has reduced toxicity risk for mammals, birds, and fish. We also find that adoption of genetically engineered insect-resistant maize varieties significantly reduced the use of organophosphate and pyrethroid insecticides, thereby reducing toxicity exposure to all examined taxa. Policies aimed at restricting neonicotinoid use may need to account for undesirable unintended consequences.

1. Pollination is an ecosystem service that directly contributes to agricultural production, and can therefore provide a strong incentive to conserve natural habitats that support pollinator populations. However, we have yet to provide consistent and convincing pollination service valuations to effectively slow the conversion of natural habitats.2. We use coffee in Kodagu, India, to illustrate the uncertainties involved in estimating costs and benefits of pollination services. First, we fully account for the benefits obtained by coffee agroforests that are attributable to pollination from wild bees nesting in forest habitats. Second, we compare these benefits to the opportunity cost of conserving forest habitats and forgoing conversion to coffee production. Throughout, we systematically quantify the uncertainties in our accounting exercise and identify the parameters that contribute most to uncertainty in pollination service valuation.3. We find the value of pollination services provided by one hectare of forest to be 25% lower than the profits obtained from converting that same surface to coffee production using average values for all parameters. However, our results show this value is not robust to moderate uncertainty in parameter values, particularly that driven by variability in pollinator density. Synthesis and applications.Our findings emphasize the need to develop robust estimates of both value and opportunity costs of pollination services that take into account landscape and management variables. Our analysis contributes to strengthening pollination service arguments used to help stakeholders make informed decisions on land use and conservation practices.
