Belize Cattle Farms : potential to produce high value timber por Detlefsen Rivera, Guillermo., Ibrahim, Muhammad Akbar, Rosa Cruz, Adriano, Santos, Tanya

“…It addresses both landowners and the country, which could obtain more environmental goods and services, since, by incorporating and managing more trees in livestock farms, farmers can improve the yields and productivity of wood resources. At the same time, Belize can improve livestock productivity, as well as the commercialization of the products obtained, and contribute to the generation of ecosystem services.…”

Differential sensitivities of electricity consumption to global warming across regions of Argentina por Propato, Tamara Sofia, De Abelleyra, Diego, Semmartin, María Gisela, Veron, Santiago Ramón

“…We sought to characterize the relationship between the EC and daily T of different regions of Argentina and use these historical relationships to estimate expected EC under T future scenarios. We used a time series approach to model EC, removing trends and seasonality and accounting for breaks and discontinuities. …”
