Policy Development for Environmental Licensing and Biodiversity Offsets in Latin America

Attempts to meet biodiversity goals through application of the mitigation hierarchy have gained wide traction globally with increased development of public policy, lending standards, and corporate practices. With interest in biodiversity offsets increasing in Latin America, we seek to strengthen the basis for policy development through a review of major environmental licensing policy frameworks in Argentina, Brazil, Chile, Colombia, Mexico, Peru and Venezuela. Here we focused our review on an examination of national level policies to evaluate to which degree current provisions promote positive environmental outcomes. All the surveyed countries have national-level Environmental Impact Assessment laws or regulations that cover the habitats present in their territories. Although most countries enable the use of offsets only Brazil, Colombia, Mexico and Peru explicitly require their implementation. Our review has shown that while advancing quite detailed offset policies, most countries do not seem to have strong requirements regarding impact avoidance. Despite this deficiency most countries have a strong foundation from which to develop policy for biodiversity offsets, but several issues require further guidance, including how best to: (1) ensure conformance with the mitigation hierarchy; (2) identify the most environmentally preferable offsets within a landscape context; (3) determine appropriate mitigation replacement ratios; and (4) ensure appropriate time and effort is given to monitor offset performance.     

Histoplasmosis: Epidemiology in Latin America

Histoplasmosis is a frequent health problem in Latin American countries, but the fact that it is not a reportable disease prevents reliable estimates of its real incidence and impact on public health. Epidemiologic and clinical data remain patchy in general, and in some countries the information available is very limited. Histoplasmosis has a significant public health impact in susceptible populations such as immunosuppressed individuals, in whom the disease is associated with poor outcomes. Limited availability of diagnostic tools in many regions of Latin America is an additional problem, as many patients are already severely ill by the time of the diagnosis. Efforts are therefore necessary to ensure early diagnosis and appropriate treatment, limit the severity of the disease manifestations, and reduce morbidity and mortality. This paper reviews important aspects of the epidemiology of histoplasmosis, the most clinically significant endemic mycosis in Latin America.

Eltor cholera in Latin America

Cholera epidemics in South and Central America in the period 1991-1999 are characterized. The mechanisms of existence of Vibrio eltor in environmental objects have been substantiated. The causes and conditions of endemic foci formation which determine the infection spread not only within the countries of the subcontinent, but also far beyond its borders are shown. The effectiveness of cholera control interventions is evaluated.
