Based on theoretical underpinnings and an empirical review of forest laws and regulations of selected countries throughout the Americas, we examine key components of natural forest management and how they are addressed in the legal frameworks of Argentina, Brazil, Chile, Costa Rica, Guatemala, Nicaragua, Paraguay, Uruguay, and the U.S.
The state of water quality of lakes is highly related to watershed processes which will be responsible for the delivery of sediment, nutrients, and other pollutants to receiving water bodies. The spatiotemporal variability of water quality parameters along with the seasonal changes were studied for Lake Okeechobee, South Florida. The dynamics of selected four water quality parameters: total phosphate (TP), total Kjeldahl nitrogen (TKN), total suspended solid (TSS), and chlorophyll-a (chl-a) were analyzed using data from satellites and water quality monitoring stations.
This river basin overview describes the state of the water resources and water use, as well as the state of agricultural water management in the La Plata basin. The aim of this report is to describe the particularities of this transboundary river basin and the problems met in the development of the water resources, and irrigation in particular.
This assessment focuses on three main services that plant protection impacts on soil can significantly affect: provisioning services for food, fibre, and fuel supply and regulating services for water quality and erosion. The Global Soil Partnership (GSP) at its 2016 plenary session requested that the Intergovernmental Technical Panel on Soils (ITPS) complete “an assessment at global level of the impact of Plant Protection Products on soil functions and ecosystems”. It is an activity under the strategic objective SO2 and indirectly contributing to all FAO strategic objectives.
Este trabajo evalúa la capacidad del modelo regional MM5 para representar las principales características del clima actual de Sudamérica. Se evalúa la distribución espacial de los valores medios estacionales, la variabilidad interanual y el ciclo anual de la precipitación y la temperatura, así como la variabilidad interna.
In the Latin American and Caribbean region (LAC), millions of families live under a constant threat of being evicted from the land and homes on which they live. The urbanization process across the region builds on an essentially unequal basis. As cities and urban populations grow, competing interest and demand for land also grows, be it for housing and food production, as well as for a variety for a variety of economic activities that depend on land.
Ecosystem services science has developed at a fast rate in Latin America, a region characterized by a high biological and cultural diversity, strong emphasis in foreign investment, and high socioeconomic inequities.
Policies play a pivotal role in determining land change. Uruguay has been subject to first a rise and then decline in plantations of exotic trees as a result of internal Uruguayan government policies, and a recent substantial increase in soybean cultivation that may be attributed to Argentinean policies. To properly assess the relationship between land change and changes in land-use policies, vegetation change for Uruguay from 2001 to 2009 was mapped using MODIS imagery.
Liu, X., Burras, C. L., Kravchenko, Y. S., Duran, A., Huffman, T., Morras, H., Studdert, G., Zhang, X., Cruse, R. M. and Yuan, X. 2012. Overview of Mollisols in the world: Distribution, land use and management. Can. J. Soil Sci. 92: 383â402. Mollisols â a.k.a., Black Soils or Prairie Soils â make up about 916 million ha, which is 7% of the world's ice-free land surface. Their distribution strongly correlates with native prairie ecosystems, but is not limited to them. They are most prevalent in the mid-latitudes of North America, Eurasia, and South America.
In this report, we present a review of the oilseed production and processing sector in Ukraine. We begin by analysing oilseed, oil and meal supply and demand, and concentrate more specifically on sunflower seed. We then proceed to discuss the main policy issues that currently have an impact in the crushing sector.
