Can we increase agricultural production without threatening biodiversity?

The world population is expected to reach 9.8 billion by 2050. This increase in population will put pressure on agriculture to produce more food. Many studies have reported that land-use changes, such as cutting down forest to make new farmland, can lead to a loss in the number of species living in an area, known as the biodiversity. It is important to maintain biodiversity because it supports healthy ecosystems and ultimately a healthy planet. A recent analysis of previously published scientific articles suggests that when farming efforts are intensified, agricultural production increases but the number of species supported by the farm decrease. This means that increasing agricultural production comes at a cost.

Community and home gardens are hotspots for pollinators in cities

Pollinators, such as bees, are important parts of the environment since they are required for plant success and fruit production by humans and animals alike. However, populations of pollinators have been declining worldwide due to a number of issues, including widespread pesticide use and loss of habitats. A recent study conducted by researchers in the UK and their colleagues examined pollinator use of urban areas, comparing community gardens, home gardens, cemeteries, and other spaces. The researchers show that the abundance and diversity of many pollinator groups was highest in community and home gardens, and suggest that urban planners should increase these spaces to boost pollinator populations.
