Los impactos del cambio clima?tico se hicieron ma?s evidentes en las u?ltimas de?cadas especialmente por la intensa quema de combustibles fo?siles que causo? la frecuencia e intensidad de los feno?menos naturales. Varios pai?ses se ven afectados por estos impactos, siendo algunos ma?s vulnerables que otros tal es el caso de la Repu?blica de Chile. Uno de sus efectos ma?s importantes es la disminucio?n de glaciares que no so?lo generara?

The Paraná delta, growing at a rate of c. 2 km2 yr-1 since 6,000 yrs, is one of the most complete record of late Holocene in southern South America. The evolution of this 17,400 km2 delta enclosed in Plata estuary, can be tracked by a series of 343 successive coastal-ridge showing a c.11 years period, in coincidence with sunspot cycle, also found in some North Hemisphere coastal-ridge successions.

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.

El objetivo del presente trabajo es abonar a la reflexión de la articulación entre la gestión de riesgo dedesastres y la equidad de género. Se presenta un estudio de caso en cuatro localidades del estado de Yucatán,México, sobre percepciones respecto al cambio climático y capacidades institucionales sobre gestión deriesgos.

This report presents a comprehensive regional assessment of the Mediterranean, Middle East, and Sahel in terms of climate change impacts, vulnerabilities, conflict/cooperation and human security at various scales and in a variety of contexts. The Climate Change, Hydro Conflicts and Human Security (CLICO) project builds on interdisciplinary and cross-comparative research covering a variety of geographical scales and historical contexts to unravel social, political, environmental/ ecological and economic conditions in relation to the environment.

This study has collated information on the role that pollution (air, water and soil pollution) has played in environmental degradation and the consequences of such degradation for human well-being, poverty. The report has primarily collated information from investigative studies that have been conducted in DFID priority countries of sub-Saharan Africa; additional information from key studies is also provided for South and
South East Asia DFID countries.

This paper focuses on water variability which is predicted to increase due to climate change. It highlights that such environmental changes may aggravate political tensions, especially in regions that are not equipped with an appropriate institutional apparatus.

Land-use and land-cover change (LULCC) represents one of the key drivers of global environmental change. However, the processes and drivers of anthropogenic land-use activity are still overly simplistically implemented in Dynamic Global Vegetation Models

South Africa experiences droughts on a regular basis, often associated with significant negative impacts on society and the economy. Droughts can be forecast, and South African climate scientists have been developing computer-generated models to forecast El Niño-induced droughts. Even so, there is a tendency to implement remedial interventions when droughts occur, rather than implementing proactive and preventative strategies. Being reactive seems to be a defining feature of South African water-resource management. This has also been the case with the 2015/2016 drought.

This policy brief by the Asian Development Bank argues that, given the negative impact of climate change on Mongolia, it is crucial to select mitigation actions that reduce vulnerability to climate change, support the achievement of national development goals, and are feasible given local constraints.

Key messages from the brief include:

• Mongolia’s total emissions are low, but its emissions per capita are relatively high and rising and are produced primarily by the energy and agriculture sectors.

Food cannot be grown without water. In Africa, one in three people endure water scarcity and climate change will make things worse. Building on Africa’s highly sophisticated indigenous water management systems could help resolve this growing crisis, but these very systems are being destroyed by large-scale land grabs amidst claims that Africa's water is abundant, under-utilised and ready to be harnessed for export-oriented agriculture.
