Forty-seven (47) Vertical Electrical Sounding data were acquired with electrode spacing (AB/2) of 500m using Schlumberger electrode configuration. Conventional curve matching techniques were used to interpret the data and obtain initial model parameters. Results of the study showed 3-7 electric layers which indicate multiple aquifer system. QQH, QHK, KHK and QQHK models were the Vertical Sounding curves obtained. The aquiferous layers make up the third and fourth layers. The resistivity of the aquifer varies from 10.74Ωm to 13201Ωm with an average of 1013.58 Ωm. Aquifer depth ranges from 6.2m to 92.5m with an average aquifer depth of 27.07m, while the aquifer thickness varies from 2.3m to 55.87m with an average of 15.61m. Transverse resistance varies from 65.34Ωm 2 to 7079.14 Ωm 2 with an average of 9966.29 Ωm 2 ; and the longitudinal conductance varies from 0.00018Ω-1 to 1.65 Ω-1 with an average of 0.026 Ω-1. From the study, 49% of the study area falls under the poor protective rating while 21% falls under the weak rating with 25% and 5% which makes up the moderate and good ratings respectively. Using the average longitudinal conductance, it is observed that the study area is moderately protected.

Since WAEMU is part of ECOWAS, we distinguish their respective dynamics as they may sometimes differ. Evolution of intraregional trade from 1995 to 2010 is proxied by the ratio of intraregional exports over total national exports over detailed bilateral trade data. As widely recognized, intraregional trade has slowly evolved at low levels since 1995. Based on gravity equations and national data, our study disaggregates some determinants of intraregional trade. As expected, bad national infrastructures affect intraregional trade, so as sectoral economic trends such as industrial and manufacturing growth. We also study whether the existence of regional leaders has positive or negative influences over intraregional trade. Adverse effects seem not to exist as the leading economies' performance appears to be positively correlated to intraregional trade. Conversely, overall economic performance of RECs' does not systematically translate into increased intraregional trade. When differenciating exports by types of goods, differences between levels of industrialization and development of RECs become more salient. SADC appears to be less regionaly integrated and is more open to global trade. Conversely, ECOWAS and WAEMU are more integrated regionally but less integrated into global trade. Beyond a political processes, intraregional exports seems therefore to be a second best solution for these countries.

These two major changes coupled to the important internal changes the "development business" has been undergoing since the late 1990s imply a shift in the way we think international solidarity. These changes mean we have to reconsider the way our development policies are currently justified, designed and implemented. Moreover, the distinction between our development policies, our international policy practices and our national priorities may also have to be reconsidered as its boundaries are more a more blurry. Policy implications of such changes will entail designing effective global policies with clear objectives grounded on a nuanced fact-based/principle-guided approach, on building renewed and differentiated partnerships and on thinking strategically on the grounds of mutual interest and international social justice rather than international assistance or economic warfare.
