Article 3, paragraph 3 For the purposes of Article 3, paragraph 3, eligible activities are those direct human induced afforestation, reforestation and or deforestation activities that meet the requirements set forth in this annex and that started on or after 1 January 1990 and before 31 December of the last year of the commitment period.

Of the agricultural land, 6.9 is used for growing crops and 6.0 is pastures.

In terms of crop management, the options include the development and introduction of tolerant resistant crops, pest and soil studies, better cropping or farming systems, improved irrigation techniques and crop rotation, as well as changes in the timing of planting of crops.

These include crop rotation, increased crop diversification, and introducing integrated pest management systems.

Shifts in rainfall patterns will certainly affect crops, particularly rice.

Work on crop and livestock improvement is conducted in close collaboration with the Consultative Group on International Agricultural Research.

Decision Support System for Agrotechnology Transfer (DSSAT) is a software system that integrates crop growth models with crop, weather and soil data and estimates potential changes in crop yields and water use.

Other negative effects of climate change include possible reductions in crop yields.

(Jordan) prevention of desertification soil improvement and crop cultivation at the pilot farm managing farming materials bank and cattle bank.

Two tier crop rotation was practiced, but farm productivity was low, around 1 ton per hectare.

These systems in turn produced crop yields that could sustain much higher population densities than competing methods of food production.

Cropping systems that include a variety of crops (polyculture and or rotation) may also replenish nitrogen (if legumes are included) and may also use resources such as sunlight, water, or nutrients more efficiently (Field Crops Res.

In 2004 the main agricultural crops were wheat, barley, corn, rice, vegetables, dates, and cotton, and the main livestock outputs were cattle and sheep.

Farm water may include water used in the irrigation of crops, water used to leach harmful salts from agricultural fields and water used for environmental management.

Increased production of agricultural crops for non food purposes offers the opportunity to utilize land that would have otherwise been an unexploited resource.

The ability of tumor cells to adapt to a wide range of environmental conditions, including toxic chemicals, is similar to the evolutionary capacities demonstrated by crop pests and other invasive species. As in the case of the Diamondback moth, successful eradication of disseminated cancer cells is rare.

It paid taxes on several agricultural items including, wheat, barley, summer crops , fruits, cotton, beehives, goats, and water buffalo.

Furthermore, less than 5 of agricultural land is irrigated, and improved crop varieties are rarely used.

The threats to sustaining such systems, such as monoculture cash crop production, mineral extraction, environmental contamination and genetically modified seeds and technology, should be addressed.

In agriculture and the agro industry, biotechnology could facilitate the development of improved crops and new products and contribute toward improving production.

How can agricultural yields be raised? What is the best way to develop aquaculture?

Some say that the miracle stemmed from an agricultural revolution that freed a large chunk of the labor force to make things rather than grow food.

Low productivity of licit agricultural crops, insufficient infrastructure and lack of access to technology, credits and markets all inhibit the generation of licit income beyond subsistence levels.

Because most crops are already grown where they do best, it is not surprising that climate models show that temperature increases will reduce yields if farmers change little or nothing.

We're going up to over a million, and someday we'll basically have samples about 500 seeds of every variety of agricultural crop that can be stored in a frozen state in this facility.

What saved Argentina over the last decade were highly favorable external conditions sky high global commodity prices and technological innovations that greatly increased farm yields.

With the US market close by, Haiti could achieve a remarkable recovery of exports of horticulture, fruits, and other agricultural products, as well as tourism and light manufactured goods.

Imagine you own a patch of land and have made it valuable through careful farming practices good seeds, irrigation, fertilizers, and bees to pollinate the crops.

That means greater investment in crop research to produce more robust and higher yielding varieties, as well as making more irrigation, pesticides, and fertilizer available.

A major problem is the fact that whiteflies and the viruses they carry can infect many different host plants, including agricultural crops, palms, and weeds.

It will eat a wide range of food plants, depending on availability, including shrubs, pasture, agricultural crops, and native and exotic vegetation.

But the severe dry spell parching croplands across the US is only the latest in a global cycle of increasingly frequent and damaging droughts.

GIEWS has been providing regular bulletins on food crop production and markets at the global level and situation reports on a regional and country by country basis since 1975.

The crop prices used by Iran in calculating the value of lost crops are not appropriate for estimating the value of crops that were not, in fact, produced.

IUCN developed a cooperative agreement with ICRISAT to work on the issue of agricultural development in the drylands.

Iran estimates the alleged reduction in crop quality by comparing crop prices in the Southern Provinces in 1991 with national crop prices.

Harvest contaminated tobacco.

Similarly, Ethiopia has made strides towards shifting agricultural policies and investing more in productivity improvements for small farmers, with increased spending helping to boost crop yields over the past several years.

Ethiopia noted that the growth of its economy is highly influenced by climate variability, particularly drought, so one of its agricultural policies is to increase production (both quality and quantity) of food crops to ensure food self sufficiency.

Several factors contributed to the crisis, including high oil prices, high demand for crops from the bio fuel sector, falling global stockpiles of food commodities, and lower cereal production.

Designed as an easy to read resource book for policymakers, the study reviews several key issues surrounding modern gene technology and its applications in the areas of crop agriculture and medicine and presents the potential benefits and challenges associated with them.

Crop eradication and alternative development

Now one third of all arable land is used to grow crops to feed livestock, not to grow staple crops for people.

Such disparities are unnecessary. Indeed, the proliferation of agricultural technology from more efficient machinery to higher yielding or more robust crop varieties has the potential to narrow the productivity gap considerably, even if differences between climates and producers remain.

如此差异本可避免 事实上 农业技术 从效率更高的机械到更鲁棒的稻种 有潜力大量缩小产量差异 即便两地气候和生产者不同
