Most of the arable soils that became deposits at the turn of the 21st century have lowered their agroecological potential. This is due to degradation processes, which manifest in various forms depending on the structure of the soil cover, types of anthropogenic impact, and farming systems used. Assessing theagroecological potential of degraded soils is becoming more complicated due to global climate change. Thus, the problem arises of developing rehabilitation soil-conservation farming systems adapted to climate change and modern socio-economic conditions.

Urban agriculture, particularly organic vegetable production is promoted because of its contribution to food security and enhanced income.  More so, organic agriculture considerably enhances the income of urban farmers who practice it. The objective was to investigate the factors that affect farmers' decision to adopt organic agriculture. Due to the contamination of vegetables with conventional agriculture systems, increasing concerns about the quality of food, the health of consumers and the environmental impacts of farming systems, organic agriculture is being promoted by the Ministry of Food and Agriculture as a means of addressing the problem. Since the introduction of organic agriculture, some farmers have adopted the technology while others have not. Sixteen farmers were selected, ten from those adopting and six from those not adopting. Semi-structured in-depth interviews were used to extract data from the participants. For those who adopted, the knowledge of their parents and forefathers on agriculture and their personal experiences by comparing their organic produce with conventional ones greatly inspired their decision on adoption. Factors leading to non-adoption are: inadequate awareness about organic farming, difficulty in controlling pests, diseases and improving soil fertility and perceived lack of market for the organic vegetables. As a result, effective extension monitoring and training are recommended to enhance the adoption and sustainability of organic agriculture.

Abstract Recent experiences and successes including the dwindling capture fisheries and global increase in aquaculture production have spurred interest in the development of commercial cage culture in Africa. This case study centres on cage culture of tilapia in Kenyan waters of Lake Victoria and in satellite dams within Lake Victoria's catchment. It reports on unique challenges and the innovative ways in which Kenyan fish farmers and fishers have had to undertake to ensure success. Increased public concern and suspicion on the long-term environmental and ecological sustainability of cage-based farming systems in the lake has been a major area of concern. This study presents ways in which farmers and researchers have managed to rear caged fish with low input fish food and feed, provide quality fish seed, use locally available materials for making cages and ensure cage security. Cage culture can be beneficial in the Lake Victoria basin as emerging constraints are resolved.

Weed science has a long history of solving weed management problems for farmers. Over the last four decades most of the solutions to weed problems have been based on herbicide technology. Thus, most crop production systems in the United States rely heavily on herbicides as the primary method of weed management. During the last decade environmentalists, farmers, agricultural scientists, policy makers, and the general public have begun to question the long-term sustainability of conventional farming systems. The sustainability of these systems is being questioned because of environmental, social, and economic concerns caused by global competition, cost of production, soil erosion, water pollution, and concern over the quality of rural life. Weeds are the major deterrent to the development of more sustainable agriculture systems. Since weeds dictate most of the crop production practices (e.g., tillage, herbicides, cultivation, row spacing) weed scientists must become the leaders of collaborative integrated approaches to agriculture systems research. New crop production systems must be developed that are less destructive to the environment, are profitable, conserve energy, and support rural community development. The goal is to facilitate the development of ecologically based alternative methods of weed management that will support crop production systems that require less tillage and herbicide inputs. To accomplish this goal, research efforts must be radically expanded in weed/crop ecology and in the development of ecologically based technologies for weed management.

Smallholder farming is considered one of the most vulnerable sectors to the impacts of climate change, variability, and extremes, especially in the developing world. This high vulnerability is due to the socioeconomic limitations and high environmental sensitivity which affect the biophysical and socioeconomic components of their farming systems. Therefore, systems’ functionality and farmers’ livelihoods will also be affected, with significant implications for global food security, land-use/land-cover change processes and agrobiodiversity conservation. Thus, less vulnerable and more resilient smallholder farming systems constitute an important requisite for sustainable land management and to safeguard the livelihoods of millions of rural and urban households. This study compares a comprehensive socioeconomic and environmental dataset collected in 2015–2016 based on household interviews of 30 farmers of highland agroforestry systems and 30 farmers of conventional agriculture systems, to determine which system provides better opportunities to reduce exposure and sensitivity. A modified Climate Change Questionnaire Version 2 of the World Overview of Conservation Approaches and Technologies (WOCAT) was applied to collect the data. The interview data are based on the perceptions of Kayambi indigenous farmers about the levels of exposure and sensitivity of their farming systems during the last decade. Descriptive statistics were applied to analyze the data from the 60 farms. Results indicate that both agroforesters and conventional farmers clearly perceived increases in temperature and reductions in precipitation for the last decade, and expected this trend to continue in the next decade. Furthermore, conventional farmers perceived greater exposure to droughts (20%), solar radiation (43%), and pests, weeds and disease outbreaks (40%) than agroforesters. Additionally, results emphasize the better ability of agroforestry systems to reduce exposure and sensitivity to climate change and variability. These findings support the well-known assumptions about the key role played by agroforestry systems for climate change adaptation and mitigation, especially in developing countries.

AbstractLivestock are important components of agricultural systems. In the U.S., one-half of total agricultural receipts come from the sale of livestock. They are the harvestors of range plants, forages, and crop residues; they level out the effects of the seasonally and variability of rainfall; they cushion disruptions in the trade and marketing of feed grains; they counteract declining soil fertility and soil erosion; and they contribute to the efficient year-round use of farm labor. Unfortunately, farmers are often not inclined to adopt alternative animal agriculture systems despite the advantages they may offer. Constraints that may be encountered include possibilities of reduced short-term profits, difficulties in adapting available technology to alternative farming systems, difficulties in shifting from specialized crop or livestock farms to crop/livestock farms, and the increased needs for labor and management. Some actions needed in the U.S. to improve livestock production in alternative farming systems are: the establishment of government policies to promote the shift of marginal lands to soil and water conserving crops and the incorporation of pastures and forages in crop rotations; research to improve the utilization by ruminants of ligno-cellulosic feeds (pastures, forages, crop residues); and programs to improve range and forest management and to lead to the development of systems that optimize the use of forages for the production of nutritionally desirable lean beef.

Chickpea is an indispensable part of agriculture in Turkey besides being an important part of sustainable farming systems and also being an important food of Turkey. However, due to various reasons such as climate, disease and price policies, there are important decreases in cultivation areas. For this reason, it is one of the products aimed to increase reproduction in Turkish agriculture with the project "Bringing Fallow Lands to Production" initiated in 2018. With the Covid-19 pandemic, it has increased its importance because it is an important source of protein in a balanced diet today, where food security is again important for all countries. This study was prepared with the data obtained as a result of the survey conducted with 633 chickpea producers in 6 provinces (Çorum, Karaman, Kırşehir, Konya, Nevşehir and Yozgat) during the 2019 production season. The number of questionnaires was determined according to the Purposive Sampling Method. The aim of the study is to reveal the general characteristics and production behavior of producers in chickpea production. For this purpose, the producer was divided into 3 clusters by Cluster Analysis. These clusters are Innovative (INV), Traditional-Neutral (T-N) and Traditional-Agriculture (T-A). As a result of the study, it was determined that the producers in the INV cluster experienced less productivity loss, and the producers in the T-A group were the producers with the highest yield loss. It can be said that while economic factors are more effective in production decisions in all three clusters, agricultural knowledge is also effective in IN cluster besides economic factors. Consequently, when it is thought that the number of producers in T-N and T-A cluster are more than the other cluster (INV) in Turkey, the production market measures are the most important factors impressing to take decisions of producers in chickpea production. However, as in the INV cluster, the participation of producers in more production will pave the way for a conscious production. This situation will contribute to the development of circular economy in agriculture as well as for sustainable agriculture systems

Land footprint is one of indicator of ecological capacity for developing sustainable agriculture systems. The study aimed to evaluate ecological capacity of integrated farming agriculture-livestock through land footprint in order to develop integrated sustainable agriculture. Research was conducted in May-August 2019 at Sekaran Village, Bojonegoro District, East Java, Indonesia. Food availability index (FAI) and feed carrying capacity index (FCC) was calculated from reports and interview. Evaluation showed annual FAI was 3.4 and FCC was 7.2 those indicated sufficiency status with foodland footprint was 143.2 ha and cattleland footprint was 759.1 ha. Total land footprint for food-feed was 759.1 ha valued below total available land for agronomic activities, i.e., 1,574 ha indicating high ecological capacity to support integrated farming systems. However, for April-May had FCC < 1 indicated insecurity fodder availability to support existing cattle population. Based on feed availability, maximum amount for cow breeding stock was 713 and for fattening was 24 cows. The fattening population could be increased up to 1,590-2,515 by increasing fodder availability through silage production, planting king grass and drought tolerant tree crops to sustain the integration.
