Adapting to water scarcity: constraints and opportunities for improving irrigation management in Khorezm, Uzbekistan por Tischbein, B., Manschadi, A.M., Conrad, C., Hornidge, A.-K., Bhaduri, Anik, Ul-Hassan, Mehmood, Lamers, John P.A., Awan, Usman K., Vlek, Paul L.G.

“…Like many irrigation schemes in Central Asia, the one in Khorezm faces a two-fold challenge: on the one side, the severe problems inherited from the past need to be remedied and on the other side, the rising supply-demand gap driven by sharpening competition for water and climate change must be dealt with. Located in the lower part of the Amu Darya basin, Khorezm irrigation and drainage scheme is particularly vulnerable to supply-demand gaps. …”

Do Anthropogenic Dark Earths occur in the interior of Borneo? Some initial observations from East Kalimantan por Sheil, Douglas, Basuki, I., German L, Kuyper, Thomas W., Limberg G, Puri, R.K., Sellato, B., Noordwijk, Meine van, Wollenberg, Eva Karoline

“…Some have argued that applying similar techniques could improve agriculture over much of the humid tropics, enhancing local livelihoods and food security, while also sequestering large quantities of carbon to mitigate climate change. Here, we present preliminary evidence for Anthropogenic Dark Earths (ADEs) in tropical Asia. …”

Climate-smart agriculture global research agenda: scientific basis for action por Steenwerth, KL, Hodson, AK, Bloom, A.J., Carter, M.R., Cattaneo, Andrea, Chartres, Colin J., Hatfield, Jerry L., Henry, K., Hopmans, JW, Horwath, WR, Jenkins, BM, Kebreab, Ermias, Leemans, R., Lipper, Leslie, Lubell, MN, Msangi, S, Prabhu, Ravi, Reynolds, Matthew P., Solis, SS, Sischo, WM, Springborn, M, Tittonell, Pablo A., Wheeler, SM, Vermeulen, Sonja J., Wollenberg, Eva Karoline, Jarvis, Lovell S., Jackson, L.E.

“…The first two themes comprise crop physiology and genetics, mitigation and adaptation for livestock and agriculture, barriers to adoption of CSA practices, climate risk management and energy and biofuels (theme 1); and modelling adaptation and uncertainty, achieving multifunctionality, food and fishery systems, forest biodiversity and ecosystem services, rural migration from climate change and metrics (theme 2). Theme 3 comprises designing research that bridges disciplines, integrating stakeholder input to directly link science, action and governance.…”

Genetic Structure of Hartebeest Populations Straddling a Transition Zone between Morphotypes por Ouma, C., Roca, A.L., Were, T, Raballah, E.O, Oguge, N.O, Jura, W.G.Z.O, Ochieng, J.W., Hanotte, Olivier H., Georgiadis, N

“…Previous analyses of mtDNA from hartebeest populations across Africa supported the refugium hypothesis; that present day hartebeest morphotypes diverged in allopatry, due to climatic changes. In this analysis of morphologically distinct populations in close geographical proximity, majority of genetic variation was found within populations, with relatively little distinction, and varying levels of subdivision, among populations. …”

Central America: fertile ground for Eco-Efficient agriculture = América central: Suelo fértil para la agricultura Eco-Eficiente por Guimarães, Elcio Perpétuo

“…Their efforts to escape from poverty are hindered by rampant degradation of soils, water, and forests, affecting about 75% of the total land area. Climate change will undoubtedly intensify the pressure on natural resources in the coming decades, making it more difficult than ever to raise agricultural productivity. …”

Turning local knowledge on agroforestry into an online decision-support tool for tree selection in smallholders' farms por Wolf, J. van der, Jassogne, Laurence T.P., Gram, G., Vaast, Philippe

“…This user-friendly and practical tool provides site-specific recommendations on tree species selection via simple graphical displays and is targeted towards extension services and stakeholders directly involved in sustainable agroforestry and adaptation to climate change. The tool is based on a simple protocol to collect local agroforestry knowledge through farmers’ interviews and rankings of tree species with respect to locally perceived key ecosystem services. …”
