“…Current SOC fixed annually by CA croplands compared to conventional tillage based agriculture in Africa (Gonzalez-Sanchez et al, 2019). The effect of CA on soil C in Southern Africa presents a mixed bag with increases, no effect and decreases in SOC reported, but on closer inspection it is noted that when all the three principles of CA are applied SOC is often seen to increase (Table 4).…”

“…Among management practices that reduce C loss are erosion control, reduced / no tillage and use of cover crops while increasing C input can be achieved through addition of compost, manure and crop residues to soils. Conservation agriculture (CA), comprising the simultaneous application of continuous no or minimum mechanical soil disturbance; permanent soil mulch cover and crop diversification, has been identified as one of the feasible and sustainable means to increase C stocks in the soil (Corbeels et al, 2019;Gonzalez-Sanchez et al, 2019).…”

Tijdens een workshop en veldbezoek in december 2019 in Zuid-Afrika bespraken we de rol van bodem C van natuurbehoud en koolstofvastlegging voor klimaatbeperking. De inzichten van de workshop omvatten: (i) Vee integreren in gewassystemen om circulariteit te bereiken, (ii) Economische en ecologische duurzaamheid is mogelijk zonder subsidie, (iii) De transitie naar duurzame landbouw kan ook traag zijn: Elke stap in de richting van duurzaamheid als een goede, (iv) Visie en liefde voor het land: een goede boer is een rentmeester van het land; en (v) Manieren om praktische, maar holistische oplossingen te vinden voor elke boerderij. During a workshop and field visit in December 2019 in South Africa we discussed the Role soil C of Conservation Agriculture and carbon sequestration for climate mitigation. The insights of the workshop comprised of: (i) Integrating livestock into crop systems to achieve circularity, (ii) Economic and environmental sustainability is possible without subsidy, (iii) The transition towards sustainable farming can also be slow: Every step into the direction of sustainability if a good one, (iv) Vision and love for the land: a good farmer is a steward of the land; and (v) Ways to find hands-on local, but holistic solutions for every farm.

“…These practices conserve soil systems, water quality, and economic returns for farmers. From my in-depth review of scientific journals such as; Berry et al (2003), Delgado et al (2011), Eagle et al (2010), Kassam et al (2019), Kinyumu (2012), Lal (2009), Mutuo et al (2005), Smith and Olesen (2010), the following strategies for adapting and mitigating climate change has been identified below.…”

The study was conducted on issues affecting the academic achievement of female students in selected primary schools of Jimma Arjo woreda while its objective was to investigate the major factors that affect the academic achievements of female students in primary schools of four sampled primary schools/Arjo primary school, Andinnet, Arbi-gebeya and Wayu Warke primary schools. Female students academic achievements show an upgrading from time to time, but still the rise is delicate when contrast to males. The finding identified the five broad categories, Family related, school related, socio-economic related, cultural related were the major factors that affect the academic achievements of females’ education. The common issues household responsibilities, low awareness of parents towards females education, parents financial problems, parents education level, lack of school facilities, school distance, the nature of teacher student relationship, the study behavior female students implement, teaching method teachers use, early marriage, less avails of role models are the main reasons for squat academic achievements of female students on education. To alleviate these upward parents awareness to wards the benefit of educating females, motivating female students, providing financial supports for the poor female students, improving school facilities and protecting female from abduction and early marriage/from any harmful traditions were recommended.

“…As a result, greater investments in research and innovations for the development and scaling of CA practices may be decided. However, we argue that the mitigation calculations and interpretations by Gonzalez-Sanchez et al (2019) are flawed and biased. Gonzalez-Sanchez et al (2019) evaluated datasets from a number of studies in Africa for their estimations of annual per-area SOC sequestration rates with CA practiced in annual or woody perennial cropping systems for four climatic zones (i.e.…”

“…In their recent study published in Soil and Tillage Research: "Meta-analysis on carbon sequestration through conservation agriculture in Africa", Gonzalez-Sanchez et al (2019) conclude that the practice of CA in Africa can effectively contribute to mitigating global warming through SOC sequestration. Gonzalez-Sanchez et al (2019) claim that the SOC sequestration potential through CA for the African continent is 143 Tg C yr -1 on 160 Mha cropland (including perennial woody crops) which corresponds to about 0.90 Mg C ha -1 yr -1 .…”
