“…Conversion of plow tillage to a system-based CA can restore soil health by reducing losses of SOC and improving use efficiency of inputs, thereby advancing the mission of COP28. Adoption of CA has been documented to improve biodiversity, adaptation and mitigation of climate change, delivery of ESs, enhancement of FNS, and increase of water security, while serving as an entry point for improving soil health and its securitization (Mugandani et al 2021;Lal 2015). The global land area under CA is estimated at 205 million ha (~506 million ac) (Kassam et al 2022), and there is a vast scope for upscaling the global adoption of CA leading to conservation and restoration of soil health.…”

There were 192 parties (countries) to the convention, and these countries signed the international treaty in 1992 called UN-FCCC. This treaty is a framework for international cooperation to combat (adapt and mitigate) the anthropogenic climate change. Some notable accomplishments of UNFCCC include The Kyoto Treaty of 1997, which was designed to legally bind developed countries to reach emission reduction targets for the first period from 2008 to 2012 and the second period from 2013 to 2020. Similarly, the 2015 Paris Agreement adopted on December 12, 2015, in Paris charted a new course in the global effort to combat climate change. The Paris Agreement (COP21) also launched the nonbinding "4 Per Thousand" (4PT) initiative, which encouraged countries to sequester carbon (C) in soil to 40 cm depth at the rate of 4 per 1,000 or 0.4% y -1 (Lal 2018). The COP22, held in Marrakesh, Morocco, from November 7 to 18, 2016, launched the initiative called "Adaptation of African Agriculture" (AAA) to climate change. The AAA initiative is aimed at reducing the vulnerability of Africa and its agriculture to climate change (aaainitiative. org/en/initiative). The AAA is focused on placing the adaptation of African agriculture as the central focus of climate debate and negotiation by the parties. It encourages identification and implementation of site-specific projects to adopt improved soil management, water conservation, climate risk avoidance, capacity building, and financing solutions. In addition to addressing climate change, the AAA initiative is also aimed at addressing the perpetual issue of food and nutrition security (FNS) in Africa. The African Union has endorsed the AAA initiative as a mechanism for channel-Rattan Lal is a distinguished university professor of soil science and is director of the College of Food, Agricultural, and Environmental Sciences

“…Given that in times of drought, even natural water reserve is limited, by principles of sustainable agriculture, it is necessary to use early warning systems for droughts and apply effective management [21,22,23,24]. Due to increasing water requirements for crops, efficient management of water resources in agriculture means efficient use of irrigation water, conservation of soil water supply, and reduction of energy consumption for irrigation [25,26,27,28].…”

Tomatoes, one of the most appreciated vegetables consumed, are crops well adapted for cultivation in arid and semi-arid conditions, the success of large yields is guaranteed by covering water consumption through irrigation. Solar Pumps - SP are driven by Photovoltaic Panels - PV (SPAPV), eliminating the dependence on electricity or diesel; they are environmentally friendly because they generate carbon-free electricity and the cost of operation and maintenance is lower. In order to preserve the water administered by drip to the tomato crop grown in solariums, mulching is used. In Husasău de Tinca, in the Crișurilor Plain, cultivation of tomato varieties without mulching (WM) and with mulching with black foil (MBF) were studied. To answer the question "How effective are water conservation measures in terms of energy independence?", two variants of SPAPVs, direct pumping (ADP) and storage tank (AST) were simulated. Considering the conditions in the solariums, tomato crops do not benefit from the contribution of precipitation, therefore it is proposed to determine the water consumption of tomatoes (ETRo), using the temperatures inside the solarium. In 2016, the average temperatures during the vegetation period were observed with an insurance of over 20 %, the irrigation norms were 6945.7 m3 ha-1, for the WM variant and 6594.0 m3 ha-1 for the MBF variant, respectively. Specific Investment (SI) is 214,795 Euro ha-1 in case of ADP and respectively 202,990 Euro ha-1 in case of ATS. The payback period (IPT) is between 2.68 years and 2.53 years for the ADP variant and between 1.63 years and 1.54 years for the ATS variant, respectively. The indications for water use and irrigation water use show that in the MBF variant the water administered by localized irrigation is better utilized than in the WM variant. In the conditions of Crișurilor Plain, the best solution for the distribution of water in solariums, with the help of SPAPVs is the mulching system of tomatoes grown in solariums (MBF) and the arrangement of the drip irrigation system with a water storage tank (ATS).

“…Several studies have shown the benefits of CA practices compared to tillage-based conventional agriculture in enabling sustainable improvement of soil productivity [16], [17] [18]. The practice of CA can increase the organic matter content in soil [19], and enhance soil biological activity [20] [21], which helps to improve soil structure and crop yields after several years of practice [22]. For [21], conservation agriculture, which enhances soil biodiversity, is a departure from agricultural intensification.…”

Conservation agriculture (CA) is one option for dealing with such a challenge, but its main difficulty in West Africa is in maintaining permanent soil cover, particularly with crop residues, due to their preferential use for livestock fodder. The aim of our study was to determine the effect of crop residue mulching on the efficiency of cropping systems based on the principles of conservation agriculture. The experimental design was based on on-station experiments, intended to assess the specific effect of different levels of crop residue mulching on the biological and chemical soil fertility parameters, while in on-farm experiments we mainly assessed the ability of farmers to actually collect crop residues for soil cover and the associated effects on weeds and yields. The on-station experimental design was in fully randomized factorial blocks comprising five treatments and three replicates. The treatments compared the conventional system, tillage and cropping without mulching, and CA systems with 1 ton, 2 tons, and 4 tons of straw per hectare in plots of 10 m 2 . The effects of CA on the macrofauna, respiratory activity, and soil chemical parameters were evaluated in the 2014 and 2015 growing seasons. For the on-farm experiments, the conventional and CA practices of 15 farmers were compared to conventional practices in 2013 and 2014 in plots of 626 m 2 . The on-station results showed that the presence of crop residue mulching induced an increase in the density of termites. A significant release of carbon dioxide (CO 2
