Management of groundwater in Africa including transboundary aquifers: implications for food security, livelihood and climate change adaptation por Altchenko, Yvan, Awulachew, Seleshi Bekele, Brida AB, Diallo, H.A., Mogbante D, Pavelic, Paul, Tindimugaya, C., Villholth, Karen G.

“…There is therefore a need for ensuring sustainability and proper management of groundwater resources through instituting proper aquifer management practices such as the establishment of groundwater monitoring systems, better understanding of the role of groundwater storage and groundwater discharges in sustaining aquatic ecosystems, understanding the interactions between various aquifers (including transboundary aquifers) and assessing the impact of increased pumping from various aquifer systems on the sustainability of groundwater abstraction. This paper provides an overview of the regional hydrogeological framework, the current state of knowledge of aquifer systems, their development potential and climate change impacts on groundwater, research gaps, and policy implications for meeting the MDGs of accessing clean water and livelihood goals in Africa.…”

Impact of global change on large river basins: Example of the Yellow River basin por Cenacchi, Nicola, Xu, Zongxue, Yu, Wang

“…Particular climatic conditions, the rapid socioeconomic development, and the absence of defined water rights have led to excessive water abstraction. During the last 50 years agricultural water use has increased by more than 250 percent, while water demand from industry and domestic use has grown even more steeply. …”

Investir dans la gestion de l eau en agriculture au profit des petits exploitants agricoles du Burkina Faso. por Evans, Alexandra E.V., Giordano, Meredith A., Clayton, Terry

“…Motor pumps used upstream of reservoirs can support profitable dry-season vegetable cultivation, but care must be taken regarding over-abstraction, pollution and conflicts. Greater adoption of motor pumps could benefit some 332,000 farming households irrigating up to 4% of the total agricultural land area at a total investment cost of USD 121 million; and (4) Combination of a range of agricultural water management options ? …”

Tätt eller brett? por Landén Helmbold, Ebba

“…The qualitative analyses show that the general/master plan lacks authority as a governing document and that strategies presented in the plan may be abandoned due to a high degree of abstraction. It has also emerged from the study that evidence based methods do not seem to have an obvious place in municipal planning.…”
