“…Jat, personal communication). Numerous favourable impacts have been reported in the global literature on CA, including for crop yields, resource (labour, water, energy) use efficiencies, timeliness of cropping practices, soil quality and ecosystem services [8][9][10][11][12][13] . Nevertheless, a meta-analysis of global yield data from 48 crops across 63 countries reported limited yield gains with full CA or with some components of CA 14 , a result that has drawn into question the wisdom of making CA a sustainable intensification priority for agricultural development programs.…”

outh Asian agriculture is a global 'hotspot' for contemporary and future climate vulnerability. Further, 1.7 billion people live in South Asia, and by 2050, that number is expected to rise to 2.4 billion. Although the region enjoys high economic growth, it suffers from extreme poverty, undernourishment and the deterioration of natural resources 1 . South Asia has more than 42% of the world's poor (earning less than US$1.90 per day), about 21% of the population is undernourished, and more than 41% of children are underweight 2 . Rapid population growth will increase the demand for cereals by about 43% between 2010 and 2050. Meeting this projected need is doubly challenging considering 94% of the land suitable for farming is already in production and 58% of agricultural areas face multiple climatic hazards such as water shortage and extreme heat stress 3 . The present situation is anticipated to worsen with climate change, with rising temperatures and changing monsoon rainfall patterns projected to cost India 2.8% of gross domestic product 4 . Although global crop productivity has more than doubled during the past decades, negative impacts on environment, biodiversity, soil quality and air quality are common 5,6 .Future food production in South Asia requires new management approaches that are efficient and climate smart to make tangible contributions to the United Nations' Sustainable Development Goals (SDGs). Conservation agriculture (CA) has emerged as an alternative to an inefficient tillage-based conventional agriculture. CA is an ecosystem approach to regenerative sustainable agriculture and land management based on three interlinked principles: (1) continuous no or minimum mechanical soil disturbance, (2) permanent maintenance of soil mulch (crop biomass and cover crops) and (3) diversification of cropping system (economically, environmentally and socially adapted rotations including legumes and cover crops), along with other complementary good agricultural production and land management practices 7 . CA helps in managing agroecosystems for improved and sustained productivity, increased profits and food

One of the long-term solutions for agriculture’s depletion of natural resources and degradation of the environment has been identified as conservation agriculture systems with proper crop and soil management. With the progress of the era, great changes have taken place in the field of agriculture. At present, it is possible to produce sufficient crops through conservation agriculture, along with economic, agronomic, and environmental benefits. Conservation techniques greatly lower the danger to food safety on a farm. CA is a farming method used to boost crop yield and sustainability that depends on three principles: minimal soil disturbance, crop rotation, and surface crop residue retention. This paper summarizes the importance, benefits, and challenges of conservation agriculture in a precise manner. In this study, we also discuss the way to increase the practice of conservation agricultureas well as the present research scenario of Bangladesh. At last, some research gaps are highlighted. Through this review, students and researchers will know the current development status of CA clearly and briefly.

“…Climate change and variability is already causing negative impacts in many parts of the world (Jat et al, 2019) particularly in Sub-Sahara Africa that is most vulnerable owing to the fact that over 70% of the population deriving their livelihoods from agriculture and natural based resource activities (Antwi, 2020). This climate change will reduce crop yields and in turn will increase the price of food that force people to change production and consumption patterns and directly will reduce calorie intake.…”

Over the last few decades, climate change and food security aspects have become increasingly important in all societies globally. However, research on climate change, its impact on agricultural production and adaptation strategies is largely focused on large scale farming systems. Furthermore, gaps exist in knowledge of climate change effects and adaptation approaches on smallholder farming systems in Kenya. The purpose of this study was to analyze the effect of Sustainable Land Use Practices on Food Security among small-holder women farmers in Shinyalu Sub-County, Kakamega County, Kenya. The study adopted a descriptive survey research design. The study targeted small-holder women farmers in Shinyalu Sub-County. The sample was determined by use of Krejcie and Morgan formula. Pilot study was carried out in the same Shinyalu subcounty; Kenya but on respondents who were not included in main study. The Questionnaire was used as an instrument for primary data collection. The study descriptive and inferential statistics was analyzed by use of SPSS software version 24, further; a regression equation model was developed to test the relationships between the variables. Results of the findings indicated Sustainable Land use Practices had an effect on Food Security among women holder farmers in Shinyalu Sub-County; Kenya. The study recommended for the policy influencers to integrate gender perspectives into mitigation and adaptation actions. Sustainable Land use actions need to be based on consultation with women, in order to build and incorporate their skills and knowledge, and to provide opportunities for improving livelihoods. Comparative studies to be conducted in other Sub-Counties and Counties on the impact of climate change mitigation and adaptation strategies on food security of women smallholder farmers.
