“…The reason for farmers' choice of growing sorghum and maize, than other crops could primarily be due to the fact that they are drought tolerant, versatile and meets farmers' need for both food and cash. This is in line with a study carried out by Kudadjie et al (2004) and Murungweni (2016) which revealed sorghum and maize as climate smart crops. The second reason could be that the sorghum crop can store well under local conditions and the stems can be eaten like sugarcane by Karamoja local people.…”

Uganda Government embarked on promoting sedentary agriculture in Karamoja agro-pastoral semi-arid livelihood zone, which experience rapid environmental and high soil quality (SQ) decline. However, studies on sedentary agriculture’s impact on soil quality using farmer’s knowledge is limited. Consequently, a survey was carried out in Karamoja (Iriiri, Matany Sub-counties of Napak of districts and Rengen sub-county of Kotido) to determine the soil quality indicator parameters based on the farmers knowledge in order to build a local soil knowledge data base to better inform sustainable land use strategies. Using a semi-structured questionnaire, forty indigenous farmers per sub-county, were interviewed between August and September, 2015. The study took into account the social demographic characteristics of the people, farming enterprises, methods of crops production, crops yields trends, causes of the perceived yields trends and soil quality indicators. Prospects of developing Karamoja indigenous knowledge data base lies in visible feature that predict soil quality. Farmers used 36 parameters to determine SQ. The parameters were clustered into five categories; soil, crop, biological, environmental and management each category contributing to 42, 19,14,8 and 17% of the total indicators, respectively. The relationship between age group and the perceived indicators of soil fertility was statistically significant (p-value = 0.045) with the majority stating that they use either soil colour, soil depth or soil texture to express the fertility of soil. The farmer’s soil quality indicators assessed in this study, is important in establishing indigenous-scientific hybrid knowledge data base to enhance soil fertility maintenance and better inform policy makers and other stakeholders on development of sustainable land use strategies.

“…This can be partially reached through growing drought-tolerant varieties while setting forth more rational strategies for exploiting landscape. The use of fertilizers and improving the soil water holding capacity represent other options (Murungweni et al, 2016). Additionally, application of innovative nanotechnologies in agriculture (including the advantageous nano-particles) has been shown to be a promising approach to improve crop production considerably (Lal, 2008;Liu & Lal, 2015).…”

Safflower is one of important crop in semi-arid regions of the world, where the precipitations are limited. In order to investigate the effect of foliar spray of nano-silicon dioxide (10 and 20 mM) and nano titanium dioxide (25 and 50 mM) and water-deficit stress (irrigation after 110 mm evaporation) on growth parameters and yield components of spring safflower a field experiment was carried out at the highland semi-arid region, in, North West of Iran. Water deficit stress significantly reduced morpho-physiological traits such as ground cover, canopy width, leaf fresh mass, leaf are and plant height) as well as yield components (e.g. capitulum diameter, seed mass and seed number per capitulum). However, the plants grown under water deficit condition showed the higher harvest index than well irrigated plants. Comparison of the foliar treatments showed that the both nano-particles (silicon and titanium) improved the plant growth and yield components over the control. However, the effect of nanosilicon was more prominent than titanium. The highest amount of seed oil was recorded under well irrigated condition (irrigation after 60 mm evaporation) with foliar application of nano-titanium. The percentage of palmitic acid, arachidic acid and myristic acid in seed increased by nano-titanium application. Altogether, principal component analysis indicated that spray of 10 mM nano silicon dioxide was best foliar treatments under all moisture regimes.Key words: safflower; agronomic traits; foliar spraying; nanoparticles; principal component analysis; semi-arid region IZVLEČEK UČINKI SILICIJA IN TITANA NA RAST ŽAFRANIKE (Carthamus tinctorius L.) V RAZMERAH POMANKANJA VODEŽafranika je pomembna poljščina v semiaridnih območjih, kjer so padavine omejene. Z namenom ugotavljanja učinkov pršenja listov z nano-silicijevim (10 in 20 mM) in nano titanovim dioksidom (25 in 50 mM) ter stresa zaradi vodnega deficita (namakanje po 110 mm evaporacije) na rastne parametre in komponente pridelka pomladanske žafranike je bil izveden poljski poskus na višinskem semiaridnem območju severno zahodnega Irana. Vodni deficit je značilno zmanjšal morfološko-fiziološke lastnosti (pokritost tal, širino krošnje, svežo maso listov, listno površino in višino rastlin) kot tudi komponente pridelka (premer koška, maso semen in število semen na košek). Kljub temu so imele rastline, ki so rastle v razmerah pomanjkanja vode večji žetveni indeks kot dobro namakane. Primerjava foliarnih obravnavanj je pokazala, da so oboji nano delci (silicijevi in titanovi) izboljšali rast rastlin in komponente pridelka v primerjavi s kontrolo. Učinek silicijevih nano delcev je bil bolj izražen kot titanovih. Največja vsebnost olja v semenih je bila v dobro namakanih rastlinah (namakanje po 60 mm evaporacije) s foliarno dodajanimi nano delci titana. Odstotki palmitinske, arahidonske in miristične kisline v semenih so se povečali po uporabi nano titanovih delcev. Analiza glavnih komponent je pokazala, da je bilo pršenje z 10 mM nano silicijeva dioksida najboljše foliarno...

“…With a mean annual rainfall of approximately 450 mm, much of the central part of southern Africa is classified as semi-arid ( Fig 2). In fact, semi-arid conditions in SSA regions are likely to increase with climate change, yet these regions are becoming more important to feed production zones due to increasing population pressure (Murungweni et al, 2015). Production systems in semi-arid regions of the world are often thought of as being particularly vulnerable to climate change.…”

“…Low lying areas tend to have less risk of crop failure during a drought but can be vulnerable to flooding. Therefore, farmers in semi-arid regions can reduce risk of total crop failure by making a clever use of both the low lying and the upland areas depending on crops of their interest (Murungweni et al, 2015). The Zimbabwe-based Africa Conservation Tillage Network (ACT), recommends breaking the soil only where seeds are to be planted, as ploughing entire fields can degrade soil.…”

“…For example, starting in December 2014, the Southern Region of Malawi received 400% higher rains than usual (compared to the Long Term Mean) causing the Shire River to reach its highest level in 30 years (OCHA, 2015). Recent studies indicated that smallholder farmers in Southern Africa are aware that climate is changing mainly through observations of rainfall and temperature trends over a long period of time; with reference to increase in temperatures and frequent drought both intra and between the seasons (Juana, Kahaka, & Okurut, 2013;Michigan State University, 2012;Murungweni, van Wijk, Smaling, & Giller, 2015).…”

Climate change has become a major threat to human developmental sectors in recent times. Agriculture is particularly vulnerable sector because it is highly dependent on climate variables. General decrease in total seasonal rainfall, accompanied by more frequent in-season dry spells are pervasive to sub-Saharan Africa, and significantly impact on crop and livestock production, and hence hamper food security in the region. The hardest hit by climate change is the rural smallholder farmers in the drier areas, owing to adaptive capacity and limited resources. As to carter the adaption needs of smallholder farmers to climate change, climate-smart agricultural approach provides much needed potential. However, to efficiently achieve climate-smart agriculture, evidence-base, and location specific framework that unpack complexity and define precise implementation pathway is urgently needed. This paper therefore, reviewed prospect of present and future climates change implications to smallholder farmers in developing countries. Thereafter, it drew upon a variety of current adaptation strategies within concept of climate smart agriculture, and assess the required support to increase the adaptive capacity of smallholder farmers' in semi-arid regions
