“…We found that farmers who rent agricultural land under tenure rights that permit cultivation for a specified period were less inclined to engage in soil management and water harvesting practices (Table 4). This finding is consistent with common knowledge and established literature [59] that poorly defined land rights can limit sustainable investments in agricultural land and water management. Although clearly defined land rights may bolster incentives for investment in land and water resources, literature on property rights and sustainability shows mixed results on investment outcomes [60].…”

2019

The rising demand for food production in a changing climate impacts water resources negatively in semi-arid agro-ecosystems. In the Tsavo sub-catchment of Kenya, this is compounded by a surging population and expansion of cropping as a land use; leading to increased abstraction of surface water resources and deterioration of related ecosystem services. The impact of increased abstraction is more profound during water stress seasons when stream-flow levels are low. While water policies have incorporated a requirement for environmental flows, unregulated abstractions persist suggesting an inherent challenge. Drawing on a sample of 279 households, we analysed farmers' engagement in water resources management and explored how this can inform water resource planning. Seasonal water scarcity and user conflicts were the major challenges experienced by the farmers. Ordinal and logistic regression models show that knowledge, attitude and practices were culture-dependent being impacted by educational attainment, level of income, access to extension and membership to local networks. Attitude and practice were further influenced by land tenure and farm distance to water sources. Since knowledge of water management issues informed attitudes and practices, improved awareness and targeted extension support are necessary in the development and implementation of policy decisions on water resources management.2 of 17 water through centralised infrastructure, such as dams, others call for consideration of decentralised on-farm technologies and practices that safeguard ecosystems [7]. There is however, a concurrence that water management approaches must strike a balance between economy and ecosystems [3,17]. Water management interventions are thus perceived as delicate balancing act with many trade-offs, particularly in water stressed river basins where trade-offs are associated with high opportunity costs [8]. While less water for food may condemn many people to hunger, less water for the environment will undermine ecosystems [8,18,19]. However, with increased knowledge of water management, water stressed environments have higher prospects for sustainable agriculture [20]. Water-efficient technologies if integrated with appropriate agronomic practices have the potential to improve food productivity while safeguarding ecosystems [20,21].Water management approaches that focus on decentralised technologies, such as on-farm surface water storage, can improve food production without allocation of additional water from the ecosystems [21,22]. As a result, decentralised water management technologies have received renewed attention in many countries that have acknowledged their contribution in sustainable agriculture [22][23][24]. Moreover, agriculture is now considered both as an integrated system and as an agro-ecosystem, providing services and interacting with other ecosystems [7]. Transitioning to sustainable agricultural water management requires broad understanding and support for changes in water policies [25,26]. However, the proce...

“…Among factors likely to hamper the adoption of CSA practices, there are socio-economic characteristics of farmers, bio-physical environment of site, and the attributes of technologies as it is new [44][45][46]. Discussing on reasons for the low adoption rates of CSA practices, [47] pointed out factors such as: lack of skills, high costs of implementing the practice, labor-intensive, unavailability of inputs and climatic constraints were likely to constraint adoption. However, consistent with previous studies [25,47] education and farmer experience are important in explaining awareness and adoption of the CSA practices within the CSV of Mali.…”

Understanding the level of adoption of Climate-Smart Agriculture (CSA) technologies and practices and its drivers is needed to spur large-scale uptake of CSA in West Africa. This paper used the Average Treatment Effect framework to derive consistent parametric estimators of the potential adoption rates of eight CSA technologies and practices in the Climate-Smart Village (CSV) site of Mali. A total of 300 household heads were randomly selected within the CSV site for data collection. Results showed significant differences in the observed and potential adoption rates of the CSA technologies and practices (drought tolerant crop varieties, micro-dosing, organic manure, intercropping, contour farming, farmer managed natural regeneration, agroforestry and climate information service). The most adopted technology was the organic manure (89%) while the least adopted was the intercropping (21%). The observed adoption rate varied from 39% to 77% according to the CSA options while the potential adoption rates of the technologies and practices ranged from 55% to 81%. This implies an adoption gap of 2% to 16% due to the incomplete diffusion (lack of awareness) of CSA technologies and practices which must be addressed by carrying out more actions to disseminate these technologies in the CSV. Results showed that education, number of workers in the household, access to subsidies, and training have a positive effect on the adoption of most of the CSA technologies and practices. The adoption of drought tolerant varieties and micro-dosing are positively correlated with access to subsidies and training. The study suggests that efforts should be focused concomitantly on the diffusion of CSA options as well as the lifting of their adoption barriers. Food Security (CCAFS) has been addressing the need for proven and effective CSA options using its Climate-Smart Village (CSV) approach. The CSV approach enables ground-breaking research on agricultural technologies and practices to define their potential to deliver on the food security, adaptation and mitigation goals of CSA. Based on the principles of participatory action research, the CSV approach enables farmers to pick practices and technologies that meet their local specific needs and allows drawing lessons on agricultural technologies and practices to inform policy decisions from local to global levels [5]. The paper by Aggarwal et al [5] provides a comprehensive overview of the CCAFS CSV approach.In Mali, the CSV approach has since 2011 been used to test and validate many CSA technologies and practices (including drought tolerant crop varieties, micro-dosing, organic manure, intercropping, contour farming, farmer managed natural regeneration, agroforestry and climate information services) with the participation of farmers. Several authors have reported successful results of CSA technologies tested and their implications for local food security [6-9] and income [10]. This notwithstanding, there is limited information on the uptake and adoption of CSA practices and technologies. In su...

Greenhouse is a very effective method of matching and has been able to contribute to food independence in various countries. Plants that are in the greenhouse must be maintained with chemical-physical parameters in order to grow optimally. Monitoring of plants in greenhouses must always be done. Some monitoring reports have been made online so that they can provide solutions as quickly as possible if there is a disturbance on the plants. Unfortunately, online monitoring is still dependent on internet networks that require network infrastructure needs that have many limitations. As a result, many agricultural lands are not covered by the internet network to monitor the greenhouse. The use of a large number of sensor nodes also affects the decline in available broadband internet performance so as to reduce monitoring performance. In this research proposed a fog network that connects the sensor node with the local fog server via a WIFI network. Sensor node has been built with a system on chips WIFI-Microcontroller ESP8266 to perform data acquisition and temperature sensor data transmission, relative humidity and light intensity using the WIFI network to the fog server. In this study testing the accuracy of sensor parameters used and network performance by comparing with the use of cloud networks. From the tests performed, the results of Mean Absolute Percent Error (MAPE) were obtained for each parameter, temperature = 1.3%, humidity: 1.9% and light intensity: 0.6%. The use of the fog network has proven to not contribute significantly to the error value of measurement data sent to the server. The use of WIFI on the fog network requires less network broadband needs when compared to cloud networks. This difference is very significant, which is an average of 253 BPS if using a fog network and 1276 BPS if using a cloud network. From the experiments conducted, the use of networks for proven to have a high data transmission speed with value 471 ms when compared to the internet network with value 1349 ms. Variations in the number of sensor nodes up to 5 nodes do not significantly affect that speed.
