Terrestrial Primary Production: Fuel for Life

primary productivity assignment

Terrestrial ecosystems rely almost exclusively on the sun's energy to support the growth and metabolism of their resident organisms. Plants are quite literally biomass factories powered by sunlight, supplying organisms higher up the food chain with energy and the structural building blocks of life. Land plants, or autotrophs, are terrestrial primary producers: organisms that manufacture, through photosynthesis, new organic molecules such as carbohydrates and lipids from raw inorganic materials (CO 2 , water, mineral nutrients). These newly minted organic compounds lock up the sun's energy in chemical bonds, providing an energy currency accessible to heterotrophs, organisms that consume rather than produce organic molecules. In this way, primary producers are an essential vehicle for energy transfer from the sun to consumers, securing energy that can be passed from one consumer to another. The energetic and carbon-rich products of primary production supply consumers, including humans, with fuel to drive their metabolism while providing essential carbon-containing compounds that form the bricks and mortar of living cells.

Ecosystem ecologists have long been interested in two related metrics of terrestrial primary production. Gross primary production (GPP) is the total amount of carbon dioxide "fixed" by land plants per unit time through the photosynthetic reduction of CO 2 into organic compounds. A substantial fraction of GPP supports plant autotrophic respiration ( R a ), with the remainder allocated to the net primary production (NPP) of plant structural biomass in stems, leaves, and fruit, labile carbohydrates such as sugars and starch, and, to a much lesser extent, volatile organic compounds used in plant defense and signaling. Terrestrial GPP, therefore, relates to NPP as follows:

NPP = GPP - R a

View Terms of Use

Where do plants invest organic compounds designated for net primary production? Consider, as an example, a mature forest. The stems, leaves, flowers, and fruit are all visible displays of aboveground NPP (i.e., growth) that accrued over time — but what about belowground (root) NPP? Most of the NPP readily observed aboveground is matched in magnitude belowground by the less visible, but equally important, production of roots. For example, root growth comprised almost half of total ecosystem NPP in a ninety-year-old Michigan forest, indicating that belowground investments in biomass by plants are substantial (Figure 1). The total standing biomass of an ecosystem is a function of cumulative NPP over time minus biomass losses from senescence (i.e., death). In the same forest, stems (including trunks and branches) are the largest fraction of standing biomass, but roots comprise a quarter of the total biomass present in the ecosystem.

Measuring Gross and Net Primary Production

Recent technological advances also allow for on-the-ground estimates of terrestrial primary production using meteorological towers that measure the uptake or emissions of CO 2 by ecosystems (Figure 2). Meteorological towers measure net ecosystem CO 2 exchange (NEE), which is equal to GPP minus ecosystem respiration or the quantity of CO 2 respired by both autotrophs (plants) and heterotrophs (primarily microbes). GPP and NPP are calculated indirectly by adding ecosystem and heterotrophic respiration, respectively, to NEE. Meteorological approaches are employed worldwide in forest, agricultural, grassland, and desert ecosystems to track terrestrial primary production. For example, the international research network FLUXNET (Baldocchi et al. 2001) supports observations of terrestrial primary production on six of seven continents.

At the global scale, satellite data combined with mathematical modeling is essential to providing worldwide estimates of terrestrial primary production. Several approaches have been used, but most notable are products derived from NASA's Moderate-resolution Imaging Spectroradiometer (MODIS), a satellite-mounted instrument that collects surface spectral, or color, data useful for tracking changes in the productivity of terrestrial and marine ecosystems. An example MODIS product is a "greenness" index of the Earth's surface used to estimate terrestrial primary production. Surface greenness and other remotely sensed data collected from space provide coarser assessments of NPP and GPP than inventory and meteorological tower based methods but have the advantage of providing estimates of terrestrial primary production for large areas where ground-based methods are not feasible.

Terrestrial Primary Production Over Time and Across the Earth's Surface

Over decades, a period that is meaningful to ecological succession, terrestrial primary production changes in response to shifts in plant competition and disturbance. Consider an abandoned field that undergoes a successional reversion back to forest. Plant communities will assemble during early succession, with fast-growing plants emerging first and because of low initial plant density there will be little competition for resources. As a result, total plant growth in the ecosystem, or NPP, will proceed at an increasingly higher rate for several years. NPP generally levels off or declines once plants start crowding one another and begin competing more intensively for limiting light, nutrient, and water resources (Figure 3). Terrestrial primary production also may change over time in response to natural disturbances such as insect outbreaks, wind, fire, and pathogens that diminish photosynthesis by reducing leaf biomass and causing plant death. Long-term increases in atmospheric CO 2 and nitrogen deposition associated primarily with fossil fuel burning generally increase plant growth over long periods of time.

Terrestrial primary production varies considerably across the surface of the Earth and among different ecosystem types. Terrestrial primary production, both NPP and GPP, vary from north to south (or latitudinally) due to gradients in plant community composition, growing season length, precipitation, temperature, and solar radiation. However, east to west (longitudinal) differences in terrestrial primary production also exist. These spatial differences are illustrated in a map of global NPP derived from NASA's MODIS satellite (Figure 4). For example, there is a precipitous decline in NPP from east to west in middle North America that is largely a function of declining precipitation. NPP generally declines from tropical regions to the poles because of temperature and light limitations. Tropical forests tend to be much more productive than other terrestrial ecosystems, with temperate forests, tropical savannah, croplands, and boreal forests all exhibiting middle levels of primary production (Table 1). Desert and Tundra Biomes, limited by precipitation and temperature respectively, contain the least productive ecosystems. In addition to climatic regulation of terrestrial primary production, disturbance, management, and land-use change (including urbanization) play critical roles in determining spatial differences in terrestrial primary production.

Figure 4: The global distribution of land and ocean net primary production (NPP) estimated from spectral data gathered by NASA's MODIS satellite Public Domain NASA Earth Observatory.

Tropical ecosystems, because of their high productivity and extensive footprint on the Earth's surface, comprise nearly half of global NPP and GPP (Table 1). Temperate ecosystems and croplands are also a substantial fraction of global terrestrial primary production, accounting for roughly a quarter of global NPP and GPP. Global estimates of terrestrial NPP range from 48.0 to 69.0 Pg (= Petagrams or 10 15 g) C yr -1 , with global terrestrial GPP estimated at 121.7 Pg C yr -1 or approximately double global NPP on land.

Haberl et al. (2007) estimated that nearly a quarter of global NPP is used by humans annually in the production of crops for food and fiber, timber for wood products and paper, and in support of livestock grazing. Humans exert an additional influence on global NPP through fires. Many ecologists are concerned that the rising global demand for biofuels, together with continued human population growth, will increase this already large human appropriation of global NPP to the detriment of ecological food webs and biodiversity.

Terrestrial Primary Production and Global Change

Considerable research in ecosystem ecology centers on understanding how climate change is affecting the primary production of terrestrial ecosystems and, conversely, how ecosystems may moderate changes in global climate by absorbing anthropogenic CO 2 emissions. Terrestrial primary production is an important ecosystem service, locking up carbon in biomass that might otherwise exist in the atmosphere as CO 2 , a potent greenhouse gas. Recent evidence suggests, however, that terrestrial NPP may be declining in response to global warming and accompanying drought, with Zhoa & Running (2010) estimating a 0.55 Pg, or about 1%, reduction in global terrestrial NPP from 2000 to 2009. Continued declines in global NPP would not only reduce carbon sequestration by terrestrial ecosystems but also compromise food security and disrupt the foundation of food webs.

7.4 Patterns of Primary Production

Primary productivity varies both geographically and seasonally. Geographically, phytoplankton abundance generally decreases as you move from coastal to oceanic waters (Figure 7.4.1). Coastal waters are more productive than the central ocean for two main reasons. First, runoff from land often contains a high abundance of nutrients which get deposited in coastal waters and stimulate production. Second, the shallower bottom along the continental shelf can trap nutrients and prevent them from sinking to greater depths. It is easier for these nutrients to be brought back to the surface when they remain trapped in the shallows. Conversely, the central ocean generally has very low primary production, as these areas are far removed from any terrestrial sources of nutrients, and the great depth prevents the deep nutrients from returning to the surface.

Global averages for ocean surface primary production are about 75-150 g C/m 2 /yr. Some highly productive areas include the California coast (200-300 g C/m 2 /year), the Southern Ocean (200-400 g C/m 2 /year), and the coast of Peru (200-400 g C/m 2 /year), all regions with significant upwelling . The central ocean, by contrast, produces less than 50 g C/m 2 /year.

figure7-1-4

Regional and seasonal changes in primary production are due to a combination of the availability of light and the amount of nutrients provided by water mixing above the thermocline . In tropical regions sunlight is plentiful throughout the year, so light is not a limiting factor. The surface water is always warm and there is always a pronounced thermocline, leading to highly stratified water that prevents the nutrient-rich bottom water from reaching the surface ( section 6.2 ). Thus productivity in tropical water is always nutrient-limited, and productivity is low throughout the year (Figure 7.4.2). Because tropical water is nutrient-poor with little phytoplankton production, the water is very clear, as is the case with water in the central ocean.

At the poles, the water is uniformly cold at all depths, so there is not much of a thermocline and little stratification, allowing mixing to occur year-round ( section 6.2 ). This mixing distributes nutrients throughout the water column, so that for much of the year productivity will not be nutrient-limited. However, the polar regions may experience several months with little or no light during the winter, and the fluctuation in light levels leads to variation is seasonal productivity. In the winter months, mixing is occurring and nutrients are abundant, but there is no light, so there is no productivity. By late spring the sunlight returns, and combined with the abundance of nutrients, a spring/summer bloom of phytoplankton occurs (Figure 7.4.2). By late summer, the nutrients have been depleted and zooplankton have been grazing on the phytoplankton, so the bloom begins to decline. In the autumn, light levels decline and prevent further production throughout the winter. But during the winter the mixing is distributing nutrients throughout the water, ready for the sun to return and stimulate a bloom in the following summer.

In temperate regions there is much more seasonal variation in the depth and intensity of the thermocline (see section 6.2 ). The thermocline is shallower and stronger in the summer, and is deeper and weaker in the winter, so mixing of deep and surface water is more pronounced in the winter months. As with the poles, this winter mixing creates nutrient-rich water during the winter, but the lack of light limits winter productivity. When light levels increase in the spring, the combination of abundant light and nutrients creates a spring bloom of productivity. By late summer there is still plenty of light, but the nutrients have been depleted by the phytoplankton bloom, and the summer thermocline has prevented further mixing, so productivity declines. In the autumn, cooler temperatures weaken the thermocline, and increasing storms cause a deeper mixed layer to form, bringing nutrients back to the surface. At the same time, there is still sufficient light available that a smaller autumn bloom occurs (Figure 7.4.2). But this bloom is short-lived, as light declines throughout the autumn and into the winter. Again, there is little production during the winter due to light limitations, but the winter storms and deep thermocline recharge the water with nutrients for the next spring bloom.

The ecosystem concept has been particularly useful and extensively employed in the study of aquatic primary productivity. The flow of energy through the system is an attractive area of investigation when it involves some process, but has a more restricted value when units of biomass are simply converted to calories. Although we are able to measure primary productivity in terms of the carbon fixed, we are not yet able to measure the actual change in the oxidative state of the newly fixed carbon. The fate of photosynthate as food for higher trophic levels is therefore dependent upon a considerable array of biological and environmental variables. Primary productivity is considered in terms of its evolution from measures of standing crop and yield, which have been gradually replaced by measures of rate of carbon uptake or oxygen production, or by measure of nutrient loss, or by change of CO 2 in the environment. Data from five lakes are used to illustrate the evolutionary thread of eutrophication and the great range in primary productivity to be expected on the basis of either unit volume or unit surface area at different trophic states. Light and nutrients are important in limiting primary productivity, and are contributing factors to the great variability which one may encounter within a given lake. Only with a sounder understanding of productivity at the base of the food-chain can we have any real hope of controlling the productivity of aquatic environments for the benefit of man.

Setting Up Your Production Company: All About LLCs

John hadity.

EP Blog-John Hadity-All About LLCs

Before you seek funding for your independent film, you need to set up a business entity for your project. This post explains how a Limited Liability Company (LLC) works and why it presents a versatile way for producers to mitigate risk while managing finances—from funding through filming and even in post.

Throughout, I’ll explain various LLC structures and functions, talk about timing, and detail how LLCs apply to international projects and co-productions.

To start, let’s go over some definitions. 

What is a Limited Liability Company (LLC)?

An LLC is a legal entity that serves as the primary rights holder on your project and is the entity through which your equity financing flows. It controls the financing and distribution for a film or television project.

There are three primary components of an LLC:

  • Members:  A production LLC often has multiple members, including investors and other key stakeholders involved in the project. Each member contributes financially or through services to the production and usually has profit-sharing arrangements, as outlined in the operating agreement.
  • Manager(s):  LLCs appoint one or more managers responsible for overseeing the day-to-day operations of the production, including budgeting, hiring crew, securing locations, and managing logistics. Managers are members of the LLC and make all the business decisions for the enterprise, including how distribution will be handled.
  • Operating Agreement:  The operating agreement outlines the rights, responsibilities, and obligations of the members and managers involved in a project—providing clarity and accountability for all parties involved. Meant to serve as a governing document, this agreement typically includes details on decision-making and conflict-resolution processes as well as profit distribution specifics. 

Basic functions of a production LLC:

  • Financing:  An LLC solicits investments from individuals, production companies, studios, and other sources. It may issue membership interests or equity stakes in exchange for capital contributions to cover pre-production, filming, and post-production expenses.
  • Production Management:  The LLC is responsible for all the logistical and creative aspects of production, including—but not limited to—scheduling, hiring personnel, securing filming locations, managing equipment rentals, and coordinating post-production activities. The LLC ensures that the project adheres to the budget, timeline, and quality standards agreed upon by producers and stakeholders.
  • Distribution and Marketing:  The LLC oversees marketing and promotional efforts to attract viewership to the project and secures distribution deals with networks, streaming platforms, and other distributors.
  • Revenue Distribution:  As revenue is generated, the LLC manages the distribution of profits according to the terms outlined in the operating agreement. Revenue can come from distribution deals, licensing agreements, or ancillary sources such as merchandise sales and streaming royalties. Payments are typically sent to investors recouping initial investments, shareholders, and residual or royalty recipients.
  • Legal and Contractual Matters:  The LLC enters into contracts and agreements with production-related parties, including talent, crew, vendors, distributors, and other third parties. It also obtains necessary clearances, permits, and insurance coverage.

Put simply, a production LLC is a central hub for coordinating all aspects of a project, from inception through release and beyond. The entity serves as a legal framework for organizing resources, managing risks, and maximizing success.

Production entities: How to choose the best option

A production entity can be established as an LLC, C-Corp, sole proprietorship, partnership, or S-corp—with LLCs and C-Corps being the most common. Each option has distinct advantages and disadvantages relating to operational flexibility, liability protection, and tax implications: 

  • Sole-proprietorships, partnerships, and S corporations  are all known as ‘pass-through entities,’ which means taxable income ‘passes through’ to the personal tax return of the owner. The owner pays personal income tax on company profits but can also withdraw profits as tax-free dividends from the company. 
  • C-corporations  pay corporate tax on income, then distribute any remaining money to stockholders. Stockholders must also pay personal income tax on money received, meaning it is double-taxed.

Productions typically utilize one of two LLC types:

  • Single Member LLCs  are straightforward to set up and manage, making them ideal for independent producers who prefer minimal administrative burden. However, they offer limited liability protection when shielding the member’s personal assets from legal claims or debts incurred by the production. Also, decision-making authority rests solely with the member, potentially limiting collaborative input and creative exchange. Single-member LLCs are often taxed as sole proprietorships by default, which may result in less favorable tax treatment than other structures.
  • Multi-member LLCs  allow for shared decision-making and resource pooling among multiple members, promoting collaboration and diversification of expertise. This setup accommodates a wider range of skills, resources, and investment contributions, enhancing operational flexibility and scalability. However, differences in vision, goals, or financial contributions have the potential to disrupt the production process. Managing relationships and resolving conflicts requires clear communication and comprehensive operating agreements.

The choice of how to structure your LLC often comes down to how the investors are involved and the producer’s desired level of control. 

In the indie film space, it’s common for producers to use two entities:  a multi-member LLC  for rights management and fundraising  and a C-Corp  for physical production. In this situation, the C-Corp handles all elements of physical production—hiring talent and crew, entering into leases, making purchases, and so on. By separating physical production activity from the LLC members, producers can both minimize the possibility of conflict leading to disruption during filming and avoid exploitation of rights issues. 

To make sure you’re set up for success, we recommend consulting legal and financial professionals to help you choose the most suitable corporate structure.

Timing is key: When to establish your LLC/production entity

Ideally, you should establish an LLC as soon as underlying rights have been secured and you are ready to start your fundraising. 

Prior to setting up your production entity, it’s important to know if you’ll be working domestically or internationally, where you’ll be filming, and if you’re pursuing a partnership or collaboration, like a co-production. Once you have answers to those questions, you can work with an entertainment accountant and attorney to determine the best corporate structure for your LLC.

How LLCs apply to international productions and co-productions

Not surprisingly, productions become more complex when filming internationally or collaborating with another individual or team via a co-production. In either case, producers must navigate regulatory requirements, tax implications, and contractual obligations across multiple jurisdictions. It may even be necessary to set up multiple entities in order to comply with regulatory tax laws and be eligible for international tax credits.  Learn more about the various types of co-production partnerships and how to vet partners in this guide to co-production.

Due to the complex nature of international filming, it’s best to speak with an entertainment attorney, experienced accountant, and incentives experts to determine the right structure for your project.

Pros and Cons of using one LLC for multiple productions

Using a single entity for multiple productions looks great on paper. Streamlined administrative processes, cost savings, and enhanced brand recognition are quite appealing! And if you establish a production entity that serves as an umbrella company for multiple projects, you can capitalize on economies of scale by consolidating resources and taking advantage of existing relationships with investors and talent.

Though the convenience factor is high, there are several potential drawbacks to consider. 

Specifically:

  • A new project may have unique financial, legal, and operational requirements that conflict with the interests of other projects under the same LLC. For example, one project may require a different investment structure or revenue-sharing model than another, leading to complexities in managing finances and fairly allocating resources.
  • Co-mingled funds get complicated, especially if you’re working on a project that continues earning revenue for months or years after its release. 
  • If one project faces legal issues or financial challenges, all assets operating under the LLC are potentially at risk. If a project fails to meet financial obligations, creditors can come after the LLC’s other assets to settle their debts. 
  • Administrative management of transient cast and crew is challenging if you merge multiple productions into one LLC, especially when distributing residuals or royalties. 
  • Errors and omissions insurance coverage gets muddied when liabilities are co-mingled. 
  • Proving chain-of-title is more difficult, which can be problematic when working with various film unions, as they require extensive paperwork for each project. 

Put simply, combining multiple projects under one LLC blurs the lines of liability and accountability.  While the idea may initially seem appealing, it’s not always the most practical choice. 

Maintaining separate entities for each project provides greater financial protection, risk mitigation, legal clarity, and creative autonomy—ultimately enhancing the likelihood of success. 

The big takeaway: Expert consultation is essential

Revolutionizing Precision in Kosovo’s Wood Production Industry and Beyond

In Kosovo's bustling wood industry, precision isn't just a preference—it's a necessity. A single miscalculation in measurement can cascade into dramatic financial losses. Some industry experts estimate that the sector loses around €6 million from measurement errors each year, severely limiting profitability for many companies. 

To address this pressing issue, USAID's Kosovo Compete Activity recently partnered with the Dekoriti Training Center to introduce the industry to the FARO M70 Laser Scanner. This advanced tool, renowned for its millimetric accuracy and ability to measure 500 points per minute, is revolutionizing the industry's approach to measurement and quality control in Kosovo. Coupled with the use of new software, the FARO M70 has become a game changer for local industry. 

Through a rigorous two-week training program, 22 representatives from 17 different companies learned to leverage the scanner in their work. The results were transformative, with companies reporting up to 50 percent reductions in both costs and time required for individual projects.  

High-tech solutions to a problem for local wood processing companies are also benefiting other critical industries in Kosovo. For example, the Dekoriti Training Center recently collaborated with a geodetic company to use the FARO M70 to assess damage to a turbine at Kosova A Power Station. 

USAID Kosovo has been a steadfast supporter of the wood industry since 2004 and remains dedicated to bolstering the sector comprehensively, enhancing its competitiveness and forging new connections and export pathways.
