During the last decade, many local governments have launched initiatives to reduce CO2 emissions and the potential impact of hydro-climatic disasters. Nonetheless, PLANNING TO COPE today barely 11% of subtropical and tropical cities with over 100,000 inhabitants have a climate plan. Often this tool neither issues from an analysis of climate change or hydro climatic risks, nor does it provide an adequate depth of detail WITH TROPICAL for the identified measures (cost, funding mode, implementation), nor a sound monitoring-evaluation device. This book aims to improve the quality of climate planning by providing 19 examples AND SUBTROPICAL of analysis and assessments in eleven countries. It is intended for local operators in the fields of climate, hydro-climatic risks, physical planning, besides researchers and students of these subjects. CLIMATE CHANGE The first chapter describes the status of climate planning in large subtropical and tropical cities. The following six chapters discuss the hazards (atmospheric drought, intense precipitations, sea level rise, sea water intrusion) and early warning systems in various contexts. Nine chapters explore flood risk analysis and preliminary mapping, climate change vulnerability, comparing contingency plans in various scales and presenting experiences centred on adaptation planning. The last three chapters introduce some best practices of weather and climate change monitoring, of flood risk mapping and assessment.

    Profil des moyens d’existence des ménages Commune de Tondikiwindi – Département de Ouallam Région de Tillaberi, Niger Zone agro-pastorale avril 2012 1. DESCRIPTION GENERALE DE LA ZONE Situé dans la partie nord de la région de Tillabéri, dans le département de Ouallam, la commune de Tondikiwindi appartient à la zone agropastorale du Niger. Sa position géographique est située entre les latitudes 15° 20 ; 14°16 nord et 1° 10 et 2° 25 est. Tondikiwindi est entouré d’un massif rocailleux d’où son appellation en langue Zarma qui signifie « entouré de pierres ». Tondikiwindi rassemble 120 402 habitants sur une superficie de 11 092 Km2 dans 87 villages administratifs. Sa population est composée de Zarma (99%), de Peuhl, de Touareg, d’Haoussa et d’Arabes. Au total, le département de Ouallam compte 260 villages administratifs dont la majeure partie fut établie il y a une centaine d’années, à la recherche de terres de cultures, de pâturages et de points d’eau. Comme le montrent les cartes ci-dessous, le département est limité par trois autres départements de la région (Filingué à l’est, Kollo au sud et Tillabéri à l’ouest) et partage sa frontière nord avec la République du Mali. Le relief de cette commune est une vaste étendue de plateaux et de collines. On y remarque aussi la présence de quelques plaines pénétrées par des vallées relativement boisées. Les ressources forestières, fauniques et halieutiques connaissent des états de dégradation très avancés depuis plus d’une dizaine d’années et continuent de l’être ; conséquences de l’action anthropique et des aléas climatiques.

  • 2.3.2 Niger Border Crossing of Torodi
    2.3.2 Niger Border Crossing of Torodi Overview Daily Capacity Customs Clearance Other Relevant Information Overview The crossing at Torodi is set up the same way as the one at Gaya and share the same challenges. Torodi hosts a Customs Office, the CNUT, Soniloga and representatives from the Police Sanitaire that are charged with controlling incoming goods. The processes normally run smoothly and can be expected to be completed within two working days. Delays can arise due to problems with internet connection, and the crossing can in period be congested. A perpetual challenge is the ratio of trucks with Nigerien registration that is enforced by the CNUT and transporters union. The rule is that two thirds (2/3) of trucks for any combined cargo should be registered in Niger. However, there is often not enough Nigerien trucks available at the ports to clear the cargo and Togolese trucks are generally cheaper. Thus the rule is often violated which can lead to problems when crossing.

Indeed, I would argue that since the paper was written there has been little advance in addressing the two fundamental issues that Lévi-Strauss raises: firstly, whether shamanistic curing techniques are in fact effective and, secondly, if they are, how they achieve their ends.1 These are questions that anthropology has to address with as much honesty as possible.

  • 12 Flood Risk Preliminary Mapping in Niamey, Niger33
    Maurizio Tiepolo31 and Sarah Braccio32 12 Flood Risk Preliminary Mapping in Niamey, Niger33 Abstract: Flood mapping is still rare in the large cities South of Sahara. The lack of information on the characteristics of floods, the orography of the sites and the recep- tors hampers its production. However, even with scant information, it is possible to create preliminary risk mapping. This tool can be used by local administrations in decision making on emergency plans or on climate change (CC) action plans. From 2010 onwards, the River Niger at Niamey (1.1 million inhabitants, 123 km2 in 2014) swelled at unseasonal times. This new river flood pattern can be linked to CC. Each flooding event affected thousands of people and homes. The steady development of areas that did not appear to be flood prone in the past is the main cause of these impacts. These areas require special measures if further impact is to be avoided in the future. This chapter presents the preliminary flood risk map of Niamey 1:20,000. The map was built up using an historic approach (flooded area derived from satellite images) and considering risk (R) as the result of hazard (H) and damage (D), R = H * D. Risk was measured according to two scenarios: medium and high probability of flooding. The inverse of the return period of river and pluvial flooding (H) and the potential damage to buildings and crops according the water depth were used. Infor- mation to measure risk components was sourced by daily rainfall and daily discharge of the River Niger from 1946 to 2014, and from high-resolution satellite images (2014).

Correia the Chaco's agricultural boom: Extensive deforestation also scars the region. Roughly 14% of the Chaco forest was cut down between 2001 and 2014. The Mennonites' success in transforming the Chaco into a ranching powerhouse now undermines their own long-sought solitude, endangers this famous forest and threatens the very existence of indigenous people who've lived in the region since time immemorial. South America’s bi-oceanic highway, which will stretch from the Pacific to the Atlantic – cutting right through Paraguay – is scheduled for completion in 2022. Credit: Joel Correia, Author provided The "new Panama Canal"—that's how some are hailing a highway now under construction in South America that spans the continent, from the Atlantic to the Pacific.
