Habitat Connectivity

Habitat connectivity and matrix restoration: the wider implications of agri-environment schemes, Donald & Evans (2006) refer to the threat that agri-business has on indigenous wildlife and the long-term problems this dynamic poses to both human and non-human species. Almost half of all land surfaces on the planet are consumed by agricultural endeavors, note the authors. Agricultural develop threatens species diversity more so than overpopulation itself. Monocrops and cash crops like soybean, rubber, and oil palm are only the most obvious means by which habitats are destroyed.

When any pristine landscape is compromised by human development, the result is an irreversible fragmentation. Agro-business does, tend to pose the greatest threat to environmental integrity and diversity. As developing nations devote increasing amounts of space to agro-business, the situation will only worsen. "Habitat Connectivity and Matrix Restoration" illustrates the political, social, and ecological implications of agro-business and inspires possible solutions. Birds, according to the authors, are one of the great indicators of habitat integrity, change, and connectivity.

Mono-crops, especially the types grown currently in developing nations, do not support species diversity, discourage indigenous bird populations, and in general alter the entire ecological integrity of the entire region. Biodiversity has an impact not just on local bird populations but other species as well. Especially considering the importance of habitat connectivity, agricultural systems must become more intelligent. Agro-environment schemes (AES) are one of the political responses to the encroaching damage of agro-business and intensive habitat destruction.

With agro-environment schemes, farmers are offered incentives that will repair past damage and make way for increased species diversification, heterogeneity among habitat connectivity, and environmental integrity. The goal of AES is matrix restoration, but the scope of AES is currently limited to wealthy and developed nations. For AES to become more meaningful, they need to be applied equally worldwide without regard for climate, geopolitics, or landscape type. England, Europe. And the United States are currently leading the way for AES, as Donald & Evans (2006) point out.

The AES are costly but may ultimately prove cost-effective as they are the equivalent of preventative medicine for ecosystems. The authors outline two types of AES, one of which is lower cost but has less of an impact; and the other which is more expensive but more effective. Long-term benefits of AES have yet to be fully realized. Yet some participants do report substantial reintroduction of species and increased biodiversity overall.

The extensive impact of AES may be significant, especially in areas where biodiversity was hurt the most by agro-business in the first place. Moreover, the authors point out that AES is effective in different landscapes and ecosystems from coastal wetlands to inland plains. Each ecosystem will require a unique AES to suit its needs. Yet there are some mitigating circumstances and variables that need to be taken into account when developing and implementing an AES. Island biogeography.
