The inability to monitor wetland drag coefficients at a regional scale is rooted in the difficulty to determine vegetation structure from remote sensing data. Based on the fact that the backscattering coefficient is sensitive to marsh vegetation structure, this paper presents a methodology to estimate the drag coefficient from a combination of SAR images, interaction models and ancillary data. We use as test case a severe fire event occurred in the Paraná River Delta (Argentina) at the beginning of 2008, when 10% of the herbaceous vegetation was burned up.

Los Sensores Remotos se han convertido en los últimos tiempos en una herramienta importante para la planificación territorial, debido a la originalidad metodológica con la cual operan y el amplio espectro de observación de la superficie terrestre. El número de algoritmos disponibles en la literatura científica, permiten tratar individualmente muchas de las coberturas terrestres y caracterizarlas en base a su comportamiento espectral. En el presente trabajo se han aplicado dos métodos de clasificación de imágenes: árboles de decisión o reglas y clasificación no supervisada.

This paper analyses the climate change projected for the near and distant future in South America using MRI/JMA (Japanese Meteorological Agency) global model simulations with resolutions of 20 and 60 km. Changes in mean climate, as well as in the annual cycles and interannual variability of temperature and precipitation are discussed. An analysis is also made of the uncertainties of the 60 km resolution model experiments. For the near and distant future, both, the 20 km and 60 km resolution MRI/JMA models project that temperature changes will be positive in all seasons.

Considers the cultural dimension of applying the land information system (LIS) concept to lands held under customary land tenure. The article recognizes that the LIS concept has been developed primarily to serve the needs of countries with a western-style land market where individual land rights are the norm. However, many countries where customary landholdings exist, or predominate, are also interested in establishing LISs to manage their land resources better. The article has three main sections.

The Mekong region has undergone rapid socio-economic growth over the past two decades alongside pronounced transformations in a number of key sectors and relations between the rural majority and increasingly-aff

This analysis and recommendations stem from USAID/Kenya’s request for an assessment of Kenya’s draft National Land Policy (dNLP).4 It was conducted under the global task order: Property Rights and Resource Governance Program, a mechanism designed and supervised by USAID-EGAT’s Land Resources Management Team under the Office of Natural Resources Management.

The consultancy required a Project Completion Report of DFID’s support to the Kenya Land Alliance (KLA) and advice to DFID on possible future activities that would support pro poor land reform in Kenya. This final report has been prepared following the comments on the draft report by the Hon Kimunya, Minister of Lands and Settlement, and senior managers in the Ministry, the responsible DFID-Kenya officials and KLA’s Co-ordinator.

Land Tenure Service (SDAA) of the Rural Development Division embarked on the preparation of a land tenure "Thesaurus", mainly covering the following sectors: legal, institutional, historical, description of space, traditional or written land tenure regulations, topographical, land management, as well as land tenure related information techniques. It is expected that the Thesaurus will serve as reference material both for the normative divisions at FAO Headquarters as well as for field experts engaged in the implementation of projects with a land tenure component.

A Land Portal Foundation se orgulha de apoiar pessoas interessadas na terra ao redor do mundo para nutrir um crescente ecossistema de informação que está informando e melhorando as decisões, políticas e práticas relacionadas à terra em todos os níveis.

Um dos principais aspectos do quadro legal moçambicano de terras é que os cidadãos Moçambicanos podem adquirir direitos de posse por herança, por ocupação pacífica ou por canais costumeiros. Estes usufruem de direitos de posse, conhecidos pelo acrônimo em língua portuguesa 'DUAT' (Direito de Uso e Aproveitamento da Terra), que podem ser possuídos individualmente ou em conjunto.

Este documento informativo é baseado nos resultados e lições aprendidas em projectos realizados recentemente em Moçambique, financiados pelo programa LEGEND do DFID, nas análises mais amplas conduzidas por esse programa, e no conhecimento e experiência prática dos autores. O documento é um resumo de um Documento mais longo sobre Política e Práticas de Norfolk, S., Quan, J. & D.
