The World Summit on Sustainable Development, held in 2002 in Johannesburg, South Africa, pledged for a significant reduction in the current rate of biodiversity loss. During the summit, representatives from various countries came together to discuss and commit to sustainable development goals. One of the major focuses of the summit was addressing the loss of biodiversity and its implications for the environment and human well-being. The pledge made was to take significant actions to reduce the current rate of biodiversity loss, aiming to protect and conserve the Earth’s diverse ecosystems and the species that inhabit them. The summit aimed to promote biodiversity conservation as a crucial aspect of sustainable development for the benefit of present and future generations.
(2) Biodiversity hotspots are regions with exceptionally high levels of species richness and high endemism. The
concept of biodiversity hotspots was introduced by British ecologist Norman Myers in 1988. Myers identified 10 biodiversity hotspots. In 1999, Conservation International collaborated with Myers and expanded the number of hotspots to 25. Since then, Conservation International has continued to reassess and update the
list, leading to the current total of 36 recognized biodiversity hotspots. (3) While increasing agricultural production is an important goal for many countries, it was not the primary focus or pledge made at the World Summit on Sustainable Development in 2002.

the central theme of the World Summit on Sustainable Development in 2002.
