Country Specific

A country-oriented methodology for attaining absolute environmental sustainability (ES) is proposed and demonstrated on the environmental sustainability index (ESI) 2002. The optimal means of deriving the ES levels/scores of the participating countries from the various ESI 2002 constructs is established and, subsequently, encoded in a real-valued evolution strategy (EvS) for the viable and flexible country-specific ES improvement towards maximal ES. The EvS employs: (a) constraints concerning the number and combinations of constructs that can be concurrently improved; (b) limited and progressively decreasing construct improvements expressing the escalating difficulty of improving any construct as the construct and/or overall ES approach(es) maximum. Demonstrations on countries with diverse characteristics and comparisons with alternative optimization methodologies highlight the versatility and applicability of the proposed procedure to any country with data that is compatible to that of the participating countries.

Environmental Sustainability Index

Milk production in the northwestern region of Rio Grande do Sul has been particularly prominent among family farmers. Given the need to diversify production in their small farms, family farmers consider dairy farming a potential alternative to increase family income. However, the environmental dimension is often sidelined when implementing or maintaining this agricultural activity. Therefore, the aim of the present study was to evaluate the environmental sustainability of milk-producing family farms in the microregion of Carazinho-RS in order to identify the environmental reality in these properties. A total of 167 properties were sampled from the ten municipalities that have the most significant dairy production in the microregion. The environmental sustainability index of the properties was identified by applying a questionnaire. Research results showed that the microregion studied has a regular environmental sustainability index. This indicates the need for some adjustments, mainly in the indicators ‘land use’ and ‘legal reserve’, which were the ones that most compromised their environmental sustainability index.
