Biodiversity-rich regions often poorer due to colonial exploitation, study finds

A surprising paradox has emerged from recent research: regions boasting the richest biodiversity are frequently the poorest. This counterintuitive finding challenges the assumption that abundant natural resources equate to economic prosperity. The study, published in the journal 'Human Ecology' by Conor Wallock of Trinity College Dublin and his colleagues, investigates the intricate relationship between biodiversity and poverty.

Researchers have termed this phenomenon 'systematic biological inequality.' They hypothesize that something is transferring the abundance derived from biodiversity away from the regions where it originates. Analyzing data from 168 countries, including World Bank poverty statistics and historical records of colonialism, the study found a stark correlation: countries with higher biodiversity tend to suffer from greater poverty and inequality.

The burden of conservation is not distributed equitably relative to the differences in poverty and biodiversity between countries.

Historically, before the era of imperialism and colonialism, the principle that 'more biodiversity means more wealth' generally held true. However, the advent of colonialism fundamentally altered this dynamic. Areas rich in biodiversity became prime targets for colonization due to their abundant resources. European powers exploited these regions for their natural wealth and labor, often restructuring their economies to depend solely on the export of specific raw materials. This legacy left many post-colonial nations with weak and inefficient governance structures, perpetuating poverty and inequality.

The responsibility for conservation, whether direct or indirect, should first be borne by countries that bear the greatest responsibility for global biodiversity loss and have the least burden of poverty.

The study highlights cotton as a prime example of this 'ecologically unequal exchange.' While diverse varieties of cotton, including more productive tetraploid types, evolved in biodiverse regions like the Americas, the arrival of Europeans led to the enslavement of local populations. Their labor was exploited for mass cotton production, fueling European industries and economic growth. This process, coupled with the transatlantic slave trade and the expansion of plantation systems, exemplifies how the evolutionary diversity of tropical regions was systematically extracted for the benefit of colonizing powers, leading to underdevelopment in the Global South and economic advancement in the North.

Furthermore, the research points to an imbalance in the burden of conservation. Current international agreements often require biodiversity-rich, poorer nations to designate more protected areas. However, Africa, despite having high biodiversity and poverty rates, has a lower percentage of protected land compared to other continents. Conversely, European nations, with lower poverty and biodiversity, have designated a larger proportion of their land as protected areas. The study argues that this unequal distribution of conservation responsibilities, driven by a flawed premise that biodiversity automatically brings wealth, effectively shifts the environmental costs onto poorer nations, echoing the exploitative patterns of colonialism.

Transferring environmental costs to poor countries and telling them that 'preserving nature is the way out of poverty' is repeating the vicious cycle of past colonialism.
