Sharma, N.Rawal, S.Kadian, M.Arya, S.Bonierbale, Merideth W.Singh, B.P.[Evaluation of advanced potatoes clones for drought tolerance in arid zone in Rajasthan, India.]Evaluation of advanced potatoes clones for drought tolerance in arid zone in Rajasthan, India.

patial self-organization of dryland vegetation constitutes one of the most promising indicators for an ecosystem’s proximity to desertification. This insight is based on studies of reaction–diffusion models that reproduce visual characteristics of vegetation patterns observed on aerial photograph...


Bastiaansen, R.Jaibi, O.Deblauwe, V.Eppinga, M.B.Siteur, K.Siero, E.Mermoz, S.Bouvet, A.Doelman, A.Rietkerk, M.[Multistability of model and real dryland ecosystems through spatial self-organization]Multistability of model and real dryland ecosystems through spatial self-organization

Studies on the enabling factors for household food security (HFS) most often used simplified econometric models looking into the links with a selected set of variables. In this research, a livelihood approach of HFS was used and aimed at determining the most significant livelihood assets for HFS ...


N’Danikou, S.Vodouhe, R.S.Bellon, M.R.Sidibe, A.Coulibaly, H.[Foraging is determinant to improve smallholders’ food security in rural areas in Mali, West Africa]Foraging is determinant to improve smallholders’ food security in rural areas in Mali, West Africa

Reference evapotranspiration (ETo) is a key factor in determining the amount of water needed for crops, which is crucial to correct irrigation planning. FAO Penman-Monteith (EToPM) is among the most popular method to estimate ETo. Apparently sometimes it is difficult to compute ETo using Penman-M...


Gafurov, ZafarEltazarov, S.Akramov, BekzodYuldashev, TulkunDjumaboev, KakhramonAnarbekov, Oyture[Modifying Hargreaves-Samani equation for estimating reference evapotranspiration in dryland regions of Amudarya River Basin]Modifying Hargreaves-Samani equation for estimating reference evapotranspiration in dryland regions of Amudarya River Basin

The use of animal draft power for soil tillage has long been a major theme of agricultural development programmes in semi-arid West Africa. The rationale for animal traction utilization ranges from increasing agricultural productivity and income to relieving the drudgery in farm work. Yet, its ad...

In this millennium, global drylands face a myriad of problems that present tough research, management, and policy challenges. Recent advances in dryland development, however, together with the integrative approaches of global change and sustainability science, suggest that concerns about land deg...

The paper summarizes research conducted at International Center for Tropical Agriculture (CIAT) on responses of cassava to extended water shortages in the field aided by modern gas-exchange and water-relation techniques as well as biochemical assays. The aim of the research was to coordinate basi...
