Risiko Kesehatan Dari Truk dan Kereta Kargo

Truk-truk dan kereta-kereta kargo barang-barang di seluruh Amerika Serikat mengeluarkan gas-gas dan partikel-partikel yang mengancam kesehatan manusia dan lingkungan. Ahli rekayasa lingkungan Profesor Tami Bond, Liang Liu, dan koleganya pada University of Illinois di Urbana-Champaign, Amerika Serikat, membuat model prediksi dampak dan risiko truk-truk dan kereta-kereta kargo barang terhadap kesehatan manusia dan lingkungan hingga tahun 2050 (University of Illinois, 11/2/2019).

Hasil riset itu dirilis oleh Nature Sustainability edisi awal 2019 (Liang Liu, Taesung Hwang, Sungwon Lee, Yanfeng Ouyang, Bumsoo Lee, Steven J. Smith, Christopher W. Tessum, Julian D. Marshall, Fang Yan, Kathryn Daenzer, Tami C. Bond, “Health and climate impacts of future United States land freight modelled with global-to-urban models.” Nature Sustainability, 2019). “Many studies use models of single systems. For example, trucks on roads, or how people use different goods as the economy grows, or how cities spread as their population increases. These systems all affect each other, so we had to connect them and see how they worked together,” ujar Profesor Bond (University of Illinois, 11/2/2019)

Riset itu melibatkan Profesor Yanfeng Ouyang dan ahli perencanaan kawasan Profesor Bumsoo Lee dan peneliti asal University of Washington, Pennsylvania State University, Pacific Northwest National Laboratory dan Argonne National Laboratory. Hasilnya, model “system of systems” yang memprediksi risiko lingkungan dan kesehatan dari tansportasi, perkapalan, kepadatan penduduk, dan kebijakan lingkungan hingga tahun 2050 (Science Daily, 11/2/2019).

“Yes, environmental policy changes could push us toward cleaner, more efficient modes of land transport or more urban compactness, but we have to think ahead and start building up the infrastructure that supports those changes now. For example, when petroleum prices spiked about 10 years ago, shippers wanted to switch from trucks to rail, but the capacity was really insufficient. Our model allows for a lot of flexibility, and this type of 'system of systems' approach should be routine when investigating policy change,” papar Profesor Tami Bond (University of Illinois, 11/2/2019)
