This document discusses precision agriculture for African smallholders. Precision agriculture is a management strategy that takes into account spatial and temporal variability to improve agricultural sustainability. For smallholders in Africa and other developing areas, there is significant natural and management-related variation in growing conditions within and between fields related to factors like soil type, climate, topography, farm type, and fertilization strategies. Understanding these sources of variation is key to improving resource use efficiency and increasing fertilizer response and yields. Low-tech precision agriculture approaches that utilize farmer knowledge and innovative, low-cost techniques show potential to increase returns while creating new jobs.

Climate Smart Agriculture: Opportunities and Stumbling blocksCIFOR-ICRAF
This presentation by Marius van den Berg from the Institute for Environment and Sustainability explains briefly what climate-smart agriculture is what effects and interrelations farm management practices associated with CSA have, how CSA was adopted and which policies enabled it and what can be taken home from that.
Agriculture in developing countries must undergo a significant transformation in order to meet the related challenges of achieving food security and responding to climate change. Projections based on population growth and food consumption patterns indicate that agricultural production will need to increase by at least 70 percent to meet demands by 2050. Most estimates also indicate that climate change is likely to reduce agricultural productivity, production stability and incomes in some areas that already have high levels of food insecurity. Developing climate-smart agriculture is thus crucial to achieving future food security and climate change goals. This seminar describe an approach to deal with the above issue viz. Climate Smart Agriculture (CSA) and also examines some of the key technical, institutional, policy and financial responses required to achieve this transformation. Building on cases from the field, the seminar try to outlines a range of practices, approaches and tools aimed at increase the resilience and productivity of agricultural product systems, while also reducing and removing emissions. A part of the seminar elaborates institutional and policy options available to promote the transition to climate-smart agriculture at the smallholder level. Finally, the paper considers current gaps and makes innovative suggestion regarding the combined use of different sources, financing mechanism and delivery systems.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

– Fertility decreases with distance from homestead
Fields close to the home receives inputs of carbon and nutrients.
– Reduced fertility in fields close to the homestead compared with more remote fields
Labor and animal manure are limiting
The variation causes variations in fertilisation response.
10. Challenges
• Lack of information
– on site-specific nutrient requirements
– on the PA, often lack of established agronomic service providers
• Lack of resource
– Access to input
– Access to technology and machinery
• Government recommendations on resource use often do not recognize
existing local variation.
