This document discusses changes in agriculture and land use in Kenya between 1983 and 2013. Some key findings include: - Agricultural intensity increased significantly over this period, with the most intensive agriculture replacing natural vegetation. - Tree cover declined overall but herbaceous plants declined more than trees. Managed trees on farms increased by over 200,000 hectares. - Land tenure impacts land use practices - adjudicated land had more intensive agriculture and tree cover compared to unadjudicated land. - Population growth and expansion of agriculture led to loss of forests like Mau Forest and encroachment into forest reserves. Agricultural intensity varied between agro-ecological zones and was influenced by rainfall and temperature.

Drivers of landcover and landuse change in Kenya 1983 t0 2013
This document discusses changes in agriculture and land use in Kenya between 1983 and 2013. Some key findings include:
- Agricultural intensity increased significantly over this period, with the most intensive agriculture replacing natural vegetation.
- Tree cover declined overall but herbaceous vegetation declined more than tree cover. Managed trees on farms increased.
- Land tenure impacted land use patterns - adjudicated land had more intensive agriculture and greater tree cover compared to unadjudicated land.
- Population growth and expansion of agriculture led to encroachment into forest reserves like Mau Forest. Agricultural intensity varied between agro-ecological zones and was influenced by rainfall and temperature.
Presentation on drivers of landcover and landuse change in Kenya
This document summarizes the key drivers of land cover and land use change in Kenya between 1983 and 2013. It finds that agricultural intensity increased significantly over this period, often replacing natural vegetation like trees. However, most tree cover loss came from herbaceous areas rather than forests. It also analyzes the impact of land tenure and property rights on agricultural practices and tree cover, finding more trees on adjudicated lands compared to unadjudicated areas. Population growth and expansion of agriculture into forest reserves like Mau are also examined as major factors influencing land use change.
Urban Process: Food & Agriculture | Biocity Studio
South Australia’s agricultural industry has had booms and downturns in the past. Agriculture and food production affects transport, pollution, water usage, waste, erosion and soil/topsoils. The food to energy output is 1 calorie of food energy produced is equal to 10 calories of fossil fuel energy consumed.
Sacred journey-multimedia-presentation-gobar-gas-plant
Bio gas is produced through digestion of cattle dung in bio gas plants, also known as gobar gas plants, located in rural villages. The objectives are to provide fuel for cooking, organic manure for households, reduce pressure on forests, and improve sanitation. The construction process involves digging a pit and building a water-tight cement cylinder with intake and outflow pipes. Cattle dung and other waste is mixed into slurry and breaks down to produce methane gas, which is then stored and piped to homes for use in cooking and lighting. Subsidies are available from central and state governments to promote construction of gobar gas plants.

1) The document discusses experiments on using rice straw mulching to improve productivity of no-till wheat grown after rice in Bangladesh.
2) Short-term rice straw mulching for 20 days after sowing was found to be as effective as retaining straw mulch, in conserving soil moisture, reducing weeds, improving nitrogen uptake and wheat root growth.
3) Both short-term mulching and retaining straw mulch led to higher wheat yields compared to no mulch. The optimum nitrogen level for highest yields was found to be 115-122 kg/ha depending on mulch treatment.
Does Aerial Interseeded Cover Crop
This study evaluated whether aerial interseeding of winter rye cover crops could ameliorate the impacts of harvesting corn residue at high rates over three years on soil properties. Corn residue was harvested at an average rate of 70.6% each year, leaving the soil vulnerable to wind erosion. The interseeded winter rye produced variable biomass but did not significantly improve soil properties or impact corn yields compared to no cover crop. While the cover crops did not fully offset residue removal impacts, their growth likely reduced wind erosion risks by covering exposed soil during residue harvesting.

This document summarizes a study on the impact of climate change and sustainable land management practices on hydrology and soil erosion in the semi-arid Segura River catchment in Spain. The study uses a hydrological model to simulate current conditions and projections for 2031-2050 under climate change and different land management scenarios. The results indicate that climate change will likely increase crop water stress, surface runoff, and soil erosion due to decreased precipitation and increased intense rainfall events. Implementing sustainable land management practices like reduced tillage and organic amendments could significantly mitigate these impacts on water availability and soil loss at both the field and catchment scales. Continued modeling work will provide ensemble predictions using different climate models and evaluate extreme events under climate

Farmers in Niger have regreened over 5 million hectares of land over 20 years through farmer-managed techniques. This has led to 200 million new trees growing without being planted, an additional 500,000 tons of annual cereal production, and feeding an additional 2.5 million people. Simple techniques like zaï holes, half-moon planting, and agroforestry have improved soil fertility, fodder production, provided shade, and increased resilience to climate change. There is a need to scale up these successful regreening efforts through community participation, communication strategies, and developing agroforestry value chains.Recommended

Bob Rees' presentation from the Sustainable Food Trust's meeting: What role for grazing livestock in a world of climate change and diet-related disease?
McCracken Uplands August 2015
The document summarizes the state of upland farming and ecosystems in Scotland. It finds that agricultural land makes up 79% of Scotland's land area, with over 60% deemed of severely limited agricultural use. Analysis shows changes between the 1950s-1990s in moorlands and grasslands. Monitoring reveals less than 50% of native woodlands and peatlands are in satisfactory biodiversity condition, with grazing and browsing the main threat. Bird populations like curlew, golden plover and meadow pipit are declining, while raven, snipe and red grouse are stable. The future of hill farming faces challenges around viability, competing land uses, and perceptions of rewilding versus farming.

Establishment of Tift 85 Hybrid Bermuda grass
The document summarizes the establishment of 15 acres of Tifton 85 Bermudagrass pasture at the EREC research facility in Summer 2013. The goals were to convert wet, unsuitable grazing land to a more productive pasture for testing bulls. In April, the land was prepared with harrowing, cultivating and applying broiler litter fertilizer. On May 13th when the temperature was 55F with light rain, the field was planted with Tifton 85 Bermudagrass using a planter with a heavy roller.
Farming
This document discusses different types of farming in Britain. It describes extensive and intensive farming, with extensive having a low yield per large area and intensive having a high yield per small area with more capital and technology. It also outlines different types of farming including arable, pastoral, market gardening, and hill farming. Hill farming focuses on sheep grazing and is suitable for mountainous regions with steep slopes. The document also discusses the Common Agricultural Policy (CAP) which aims to support farmers and ensure food security through guaranteed prices and subsidies.

The LiveM theme of the FACCE-JPI MACSUR Knowledge Hub brings together 30 institutes from 14 European countries with expertise in a diverse range of disciplines, from grassland and farm-scale modelling through to livestock disease and health research.
Climate change, food security, and agricultural production interact in complex ways. A major challenge for scientists is to understand and assess the biological, economic, and ecological interdependencies in the context of climate change and food security. More and better knowledge is necessary to aid politicians, stakeholders and farmers in their decisions.
The event has four major goals:
• to critically discuss the state-of-the-art and future perspectives of integrated assessment approaches
• to study and assess examples of applied modelling approaches integrating crop, livestock, and economic models
• to foster international collaboration in the research areas of food security, climate change, and agrosystem modelling
• to plan and identify next steps to achieve TradeM contributions to MACSUR goals

Geographical factors affecting agricultural sector and service sector
Geographical factors influence both the agricultural and service sectors. For agriculture, natural factors like climate, soil, and topography determine what crops can be grown and how productive the land will be. Economic factors such as market access, transportation, labor availability and capital investment also shape the type of farming practiced. Social and political systems further impact agriculture through policies, land ownership structures, and subsidies. For services, key geographical factors include the availability of raw materials, power, labor, transportation, access to markets, water, suitable land, and supportive climate conditions which determine where industries can successfully locate and operate.
Australian public policy to mitigate and adapt agriculture for climate change...
Australian agriculture contributes around 15% of the country's greenhouse gas emissions, similar to the global proportion. The Australian government has implemented several policies to mitigate agricultural emissions and support farmers in adapting to climate change, including establishing a carbon price, the Carbon Farming Initiative (CFI), and incentives for practices like no-till farming. The CFI operates through approved methodologies for emission reduction or carbon sequestration projects. However, many farmers remain uncertain about how climate policies may impact their operations or are concerned about complexities of the carbon offset market.
Resilience of rubber based agroforestry facing global change
1. Tree-soil-crop interactions in rubber agroforestry systems can be managed at the plot, farm, and landscape levels. At the plot level, a mixed-age stand can be maintained for cash flow while diversifying. At the farm level, credit can cover replanting costs until cash flow is positive. At the landscape level, policy harmonization across forest and agriculture is important.
2. Agroforestry is understood as applying at the plot, landscape, and governance levels, reflecting the interface of agriculture and forestry. It involves tree-soil-crop-livestock interactions as well as interactions between tree cover, livelihoods, and ecosystem services across landscapes.

DryDev Closeout Webinar 30th June 2020
The DryDev programme aimed to transform lives and landscapes in dryland areas through sustainable rural development. Over six years, it worked with over 164,000 smallholder farmers across five countries in Africa. Key achievements included rehabilitating over 163,000 hectares of land through watershed management and planting over 4.6 million trees. It also increased food security and incomes by expanding irrigation to over 16,000 hectares, utilizing over 950 water harvesting structures, and promoting climate-smart agricultural practices on over 60,000 hectares.
Farmland Biodiversity
This document discusses measuring biodiversity on farmland. It notes that 60% of ecosystem services have been impaired and over 20% of global agricultural land is degraded. Assessing farmland biodiversity is challenging due to high spatial variability. Protocols for landscape-scale assessment include measuring land cover, trees, birds, and modeling remote sensing data with ground calibration. Optional protocols examine linear tree features, pollinators, natural enemies, and soil organisms. A farmland biodiversity score is proposed that weighs biomass, spectral diversity, neighborhood effects, and slope/proximity to water.

This document discusses funding gaps and principles for successful financing of nature-based solutions (NBS) such as land restoration projects in Africa. It notes that while the Bonn Challenge and New York declaration on Forests call for $350 billion and $830 billion respectively for restoration, actual funding leaves large gaps. It advocates for bridging these gaps through public-private partnerships and prioritizing long-term sustainability over short-term profits. Six principles are outlined for financing NBS, including ensuring social and environmental safeguards, monitoring impacts, and directing funds toward low-carbon development in developing countries. The Regreening Africa program addresses livelihoods, biodiversity and climate change through land restoration projects across eight African nations.Forest and agroforesty options for building resilience in refugee situations:...

This document discusses agroforestry systems for environmental restoration in Brazil that balance social and ecological functions. It outlines that agroforestry can: (1) maintain ecosystem structure/functions like biodiversity and soil quality while providing social/economic functions for family farms; (2) perform restoration in an economically feasible way by including people and accelerating natural succession; and (3) improve livelihoods through appropriate management. However, balancing trade-offs between social/environmental benefits and costs is challenging. The document then provides examples of agroforestry systems for restoration in Brazil and their costs, benefits for climate change adaptation/mitigation, food security, and carbon storage potential.Vulnerabilities of forests and forest dependent people
This document discusses the vulnerability of forest-dependent people and forests to climate change. It notes that over 1 billion people depend on forests for their livelihoods, while 1 billion hectares of land are under agroforestry worldwide. Climate change poses direct risks like increased temperatures and wildfires, and indirect risks through impacts on species and ecosystems. Potential transition issues from policies like REDD+ could negatively impact land and tree rights of indigenous groups. The document argues that comprehensive vulnerability assessments are needed using qualitative and quantitative methods to understand all vulnerabilities, include stakeholders, and identify good practices to address risks to forests and forest-dependent communities from climate change.

However, balancing trade-offs between social/environmental benefits and costs is challenging. The document then provides examples of agroforestry systems for restoration in Brazil and their costs, benefits for climate change adaptation/mitigation, food security, and carbon storage potential.Vulnerabilities of forests and forest dependent people
This document discusses the vulnerability of forest-dependent people and forests to climate change. It notes that over 1 billion people depend on forests for their livelihoods, while 1 billion hectares of land are under agroforestry worldwide. Climate change poses direct risks like increased temperatures and wildfires, and indirect risks through impacts on species and ecosystems. Potential transition issues from policies like REDD+ could negatively impact land and tree rights of indigenous groups. The document argues that comprehensive vulnerability assessments are needed using qualitative and quantitative methods to understand all vulnerabilities, include stakeholders, and identify good practices to address risks to forests and forest-dependent communities from climate change.
Pests and diseases of trees in Africa: review of a growing emergency
An increasing multitude of insect pests and pathogens is targeting indigenous trees of natural forests, agroforestry systems, and exotic trees in planted forests in Africa. This is raising major concerns for a continent already challenged by adaptations to climate change, as it threatens a vital resource for food security of rural communities, economic growth, and ecosystem conservation. The accidental introduction through trade of non‐native species in particular is accelerating, and it adds to the damage to tree‐based landscapes by native pests and diseases. Old‐time and new invaders heavily impact planted forests of exotic eucalypts, pines, and acacias, and are spreading quickly across African regions. But many non‐native pathogens are recently found affecting important indigenous trees.
Wall posters on habitat distribution of nine tree species in Ethiopia
Species distribution modelling is being used to map the habitats of over 150 priority African plant species. More advanced modelling methods are being used to reduce bias, including spatial folding and thinning. Presence observations from across Africa are being used to calibrate provisional distribution models for individual species in countries like Ethiopia. The results will then be verified by botanists and combined with vegetation mapping data.

Not all roads lead to Rome: Inclusive business models and responsible finance...World Agroforestry (ICRAF)
The document discusses approaches to achieving sustainable cocoa production in Ghana by 2020. It identifies several challenges in the cocoa sector including low productivity, rural poverty, and deforestation. It analyzes different stakeholder approaches and finds they mainly focus on increased productivity, while social and environmental issues are addressed less. Inclusive business models include many smallholder farmers but benefits are not always equitable. Responsible finance from impact investors and social lenders has potential to leverage more equitable models and landscape restoration, but investments have not been well adapted for cocoa sectors. A "multi-chain approach" is proposed to better leverage finance through a portfolio of value chains at the landscape level.Decent work and economic growth: Potential impacts of SDG 8 on forests and fo...

With an extension of 2.1 million ha, the Maya Biosphere Reserve (MBR) in Petén, Guatemala is the largest protected area in Central America. To reconcile forest conservation and socio-economic development, community forest concessions were created in its Multiple Use Zone (MUZ) in the late 1990s and early 2000s. Operated by a community forest enterprise (CFE), and with a cycle of 25 years, the concessions grant usufruct rights to local communities on an area of about 400,000 ha. Currently, nine concessions are active, while the contracts of two concessions were cancelled and the management plan of another suspended.

Sustainable land management for improved livelihoods and environmental sustai...World Agroforestry (ICRAF)
A healthy viable multifunctional landscape has the capability of supporting sustainable agricultural productivity, providing agroforestry and forest products (timber, fuel wood, fruits, medicine, fertilizer, gum etc.) for the sustenance of mankind while providing other environmental services. However these products are increasingly becoming unavailable due to declining soil fertility, climatic extremes, and high costs of inputs. Identifying low-cost, sustainable ways to attain food security and sustainable environment for millions of smallholder farmers in Sub Saharan Africa (SSA) remains a major developmental challenge.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.Energy Efficient Video Encoding for Cloud and Edge Computing Instances
