Insect decline, an emerging global environmental risk

A new paper in Current Opinion in Environmental Sustainability reports that the Earth’s entomofauna seems in an ongoing state of collapse. Insect decline could pose a global risk to key insect-mediated ecosystem functions and services such as soil and freshwater functions (nutrient cycling, soil formation, decomposition, and water purification), biological pest control, pollination services and food web support that all are critical to ecosystem functioning, human health and human survival.

At present the attention for insect decline is low in all domains, ranging from scientific research to policy-making to nature conservation. Scientists made urgent calls to prioritise insect conservation. An international treaty for global pollinator stewardship and pollinator ecosystem restoration is urgently needed to counteract the current crisis.

A review of insect pollinator conservation policies found that despite scientific calls and public outcry to develop polices that addresses declines, governments have not delivered such legislation, nor have they met basic monitoring needs recommended by experts.

Pollinators and Global Food Security: the Need for Holistic Global Stewardship

Over the past decades, both wild and domesticated insect pollinators are in dramatic decline, which puts at stake the existence of species, ecosystem resilience and global food security. Globally, 87 of major food crops depend on animal pollination. Together these account for 35 % of the world food production volume. Pollinator mediated crops are indispensable for essential micronutrients in the human diet. Many ornamental plants as well as crops for fibre, fodder, biofuels, timber and phytopharmaceuticals also depend on insect pollinators. This article aims to map the current situation of pollinators worldwide, with a focus on the critical role of pollinators in the human food chain and ecosystem sustainability, their intrinsic and extrinsic value, as well as the causes of their declines and the interventions needed to conserve them, in order to develop an argument for the importance of conserving and restoring pollinator populations and diversity. The present pollinator crisis threatens global and local food security, can worsen the problems of hidden hunger, erodes ecosystem resilience, and can destabilise ecosystems that form our life support system. An integrated approach that simultaneously addresses the key drivers is needed. This includes creation and restoration of floral and nesting resources, a global phase out of prophylactic use of neonicotinoids and fipronil, improvement of test protocols in authorisation of agrochemicals, and restoration and maintenance of independence in regulatory science. The authors argue that an international treaty for global pollinator stewardship and pollinator ecosystem restoration should be initiated in order to systemically counteract the current crisis.
