“…RANET is a USAID-funded dem-onstration project, which includes the Soudano-Sahel nations of Senegal, Niger, and Chad, along with three nations in eastern and southern Africa. (Kirshen and Flitcroft 2000;Ingram et al 2002), no progress has been made for drought-prone West Africa since Glantz's (1977) responses to several hundred questionnaires administered in the region, the study identifies the sources and pathways of climate information flow, and assesses the accessibility to such information among rural inhabitants, planning agencies, and policy makers 30 yr after the zone was first devastated by a drought that triggered the subsequent global focus on extreme regional climate variability (Lamb 2002 (Hess et al 1995;Bello 1996). Such high variability complicates the rain-fed agricultural activities and cattle herding on which a large majority of the population depends, making the socioeconomic fabric of the zone highly tenuous.…”

“…The growing season is the period of the rainfall duration from rainfall onset to cessation. It is known as the wet season, which extends from March to October in Southwestern Nigeria (Adejuwon et al, 1990;Bello, 1996;Adejuwon, 2010). In the regression analysis, the dependent variable was the yield of cassava while the independent variables were mean annual rainfall and temperature (maximum and minimum).…”

This study examined cassava yield response to variable climate in the humid forest agro-ecological zone of Nigeria. The data employed for this study was sourced from the archives of Nigeria Meteorological Agency, Lagos State and Ogun State Agricultural Development Program, Abeokuta. Bivariate correlation, multiple regression and Z-distribution were employed for data analysis. Results show that monthly, seasonal and annual rainfall did not affect the yield of cassava but monthly, seasonal and annual minimum and maximum temperature was significantly related to cassava yield at p ≤ 0.05. Non-climatic factors have a greater influence on cassava yield than climatic factors in the study area. Nevertheless, climatic factors influenced cassava yield more at Abeokuta than Ijebu-Ode. Cassava yield was lower from 1987-1993 (with negative significant impact in 1987 and 1988 at p ≤ 0.01) than 1994-2012. These results demonstrated that climate variability needs to be taken into account in cassava impact assessment.

“…The length of growing season often determines which crops could grow in an area, as some crops require long growing seasons, while others mature rapidly. Among researchers that have emphasized linkages of the growing season with reliable onset of rains are Dagg (1965), Bello (1996), Olaniran (1984), Ati et al (2002), and Sawa and Ibrahim (2011).…”

Since the inception of the present Government in May 2015, it has been battling with socio-economic problems ranging from economic recession, fall of crude oil prices in the international markets and insecurity challenge, among others. To achieve sustainable development goals, Government focused on agriculture as the best option for tackling such problems. It is against this background that this paper aimed at assessing the length of growing season in the Sudan Savanna Ecological Zone of Nigeria using daily rainfall data recorded at nearby stations from 1981 to 2010. It assessed the level and mean length of growing season in Kano, Katsina, Maiduguri, Potiskum, Gusau and Sokoto, all of which are located within this ecological zone. Data analysis involved the use of descriptive statistics to compute cumulative pentade rainfall and ogive of cumulative pentade rainfall. Using pentade and Julian day calendars, an annual ogive of cumulative pentade rainfall was drawn using Microsoft Excel for each study location and length of growing season determined from 1981 to 2010. Results obtained indicate that mean length of growing season for the study area was approximately 125 days, a duration that is slightly longer than four months. To achieve sustainable development in agriculture, the study recommends that agricultural policies in the study area should take into consideration the rather short mean length of growing season in the study area while exploring effective and feasible water conservation techniques to complement rainwater.
