Urban containment: An effective tool for environmental protection?

This paper examines the effectiveness of urban containment policies to protect forestland from residential conversion and to increase the provision of forest public goods in the presence of irreversible investments and policy uncertainty. We develop a model of a single landowner that allows for switching between competing land uses (forestry and residential use) at some point in the future. Our results show that urban containment policies can protect (even if temporarily) forestland from being developed but must be supplemented with policies that influence the length and number of harvesting cycles if the goal is to increase nontimber benefits. The threat of a development prohibition creates incentives for preemptive timber harvesting and land conversion. In particular, threatened regulation creates an incentive to shorten rotation cycles to avoid costly land-use restrictions. However, it has an ambiguous effect on forestland conversion as the number of rotation cycles can also be adjusted to maximize the expected returns to land. Finally, in the presence of irreversibility, forestland conversion decisions should be done using real option theory rather than net present value analysis

As razões justificativas deste apontamento sobre a presença e o papel históricos do arco, enquanto instrumento bélico, na Baixa Idade Média inglesa decorrem da inclusão do Professor Hélio Osvaldo Alves no júri de doutoramento da dissertação Príncipe dos Ladrões: Robin Hood na Cultura Inglesa (c.1377-1837), por nós apresentada à Faculdade de Ciências Sociais e Humanas da Universidade Nova de Lisboa em Julho de 1996. Embora nessa altura conhecêssemos já o fascínio do Professor Hélio Alves por figuras, movimentos e projectos ‘marginais’ ou ‘marginalizados’ (fascínio que, diga-se de passagem, nos habituámos a atribuir também à sua transbordante humanidade, à capacidade alquímica de fundir inconformismo e compaixão e ao exercício solidário --- e às vezes decerto solitário --- do direito à indignação moral e cívica), foi ainda assim com surpresa que deparámos, numa das suas últimas obras e a propósito dos Luditas, com “Robin Hood revisitado” (Alves, 2002: 77-96).
