PARADIGMA PENGEMBANGAN LAHAN

GARDEN APARTMENT

A garden apartment complex consists of low-rise apartment buildings built with landscaped grounds

surrounding them.

The apartment buildings are often arranged around courtyards that are open at one end.

A garden apartment has some characteristics of a townhouse: each apartment has its own building

entrance, or just a few apartments share a small foyer or stairwell at each building entrance.

Unlike a townhouse, each apartment occupies only one level.

Modern garden apartment buildings are never more than three stories high,

since they typically don't have elevators/lifts.

However, the first "garden apartment" buildings in the United States, developed in the early 20th century, were

five stories high.

Some garden apartment buildings place a one-car

garage under each apartment. The grounds are more landscaped than for

other modestly scaled apartments.

GARDEN APARTMENT

A garden apartment is a living unit located at ground level on property that is usually landscaped.

Although the term garden apartment is often used loosely to describe any first floor apartment such as one in a high rise or basement, a true garden apartment has no household above

it. Garden apartments are not vertically stacked, but rather horizontally spread out in an open area that may have a

courtyard. Garden apartments are found all over the world.

Attractive garden apartments have well cared-for grounds with flowers and trees. The owners of the apartment property are

responsible for the upkeep of the outdoor areas. If an area for dogs is included, then tenants are responsible for cleaning up

after their pets. Some garden apartments may include a small yard, but most have a patio. A garden apartment patio can be a nice place to have a barbecue or outdoor meal or just enjoy some fresh air

if the grounds are well maintained.

Faktor Penyebab Konversi Lahan Sawah

Menurut Pasandaran (2006), paling tidak ada tiga faktor, baik sendiri-sendiri maupun

bersama-sama yang menentukan konversi lahan

sawah, yaitu:

1. Kelangkaan sumberdaya lahan dan air

2. Dinamika pembangunan3. Peningkatan jumlah

penduduk.

Pembangunan kawasan pusat pasar di pinggiran kota dilakukan dengan mengkonversi lahan sawah irigasi yang produktif. “Land development “

mengorbankan jasa-jasa lingkungan dari ekosistem sawah

Foto . smno-2011

Menurut Irawan (2005), konversi lahan pertanian

pada dasarnya terjadi akibat adanya persaingan

pemanfaatan lahan pertanian dengan non-

pertanian. Sedangkan persaingan

pemanfaatan lahan muncul akibat adanya

tiga fenomena ekonomi dan sosial yaitu :

a) keterbatasan sumberdaya lahan,

b) pertumbuhan penduduk, dan

c) pertumbuhan ekonomi.

Lessons In Sustainable Land Development

Increased rates of deforestation, unsustainable agricultural land

use, and severe soil degradation are creating widespread poverty and

environmental degradation in developing countries.

Each day; the world loses about 125 square miles of its forests. That’s 34.5 million acres or 14

million hectares every year Most of this takes place in the

developing countries of the humid tropics.

Reforestation efforts are limited to only about 10% of the total area and most efforts are not

promising.

Penyebab Global Warming: Deforestasi, terutama hutan tropis untuk kayu, pulp, dan lahan pertanian.

Penggunaan hutan untuk bahan bakar (baik kayu dan arang) merupakan salah satu penyebab deforestasi. Di seluruh dunia

pemakaian produk kayu dan kertas semakin meningkat, kebutuhan akan lahan ternak semakin meningkat untuk

pemasok daging dan susu, dan penggunaan lahan hutan tropis untuk komoditas seperti perkebunan kelapa sawit

menjadi penyebab utama terhadap deforestasi dunia. Penebangan hutan akan mengakibatkan pelepasan karbon

dalam jumlah besar ke atmosfir.

Lessons In Sustainable Land Development

Every year, the equivalent of 40 billion tons of carbon dioxide enters the global atmosphere, the result of the ever-increasing use of fossil

fuels.

This increase in atmospheric carbon, in combination with the loss of forests has

combined to make global climate change worse.

Lessons In Sustainable Land

Development

The adoption of sustainable agriculture is often proposed

as a solution to these problems.

Sustainable agriculture is concerned with agricultural

practices that are economically viable, meet human needs for food, are

environmentally friendly, and improve quality of life.

Agroforestry is one such land use practice that maintains sustainability at its core.

Maksimalisasi Tutupan Hijau Lahan dengan Agroforestry

Agroforestry : penggunaan lahan, dimana tanaman keras berkayu (pepohonan, perdu, palem, bambu, dsb) ditanam secara bersamaan dalam unit lahan yang sama dengan

tanaman pertanian dan/atau ternak, dengan tujuan tertentu, dalam bentuk pengaturan ruang atau urutan waktu, dan didalamnya terdapat interaksi ekologi dan ekonomi di

antara berbagai komponen yang bersangkutan.

Lessons In Sustainable Land Development

Deforestation is a major unsustainable land use practice. Yet

little is being done to address its economic, environmental and

ecological impact.

Clear-cut logging, uncontrolled brush and forest fires, and traditional slash

and burn agricultural techniques have damaged the environment as well as

the agricultural resource base.

Additionally, every year, reforestation efforts that intend to help

communities are actually assisting in planting the wrong types of tree species, resulting in long term

damage. This concerns all of us, especially the families who rely on

trees for the basic necessities of life: fuel, water, food, building materials,

and the air we breathe. Diunduh dari sumber: http://rianyudistira13.blogspot.com/2010/10/penggundulan-hutan.html…

Penggundulan Hutan Manusia selalu menebang pohon tanpa

mempertimbangkan keseimbangan alam. Penebangan secara sembarangan meliputi kegiatan penebangan,

pengangkutan dan penjualan kayu yang tidak sah dan tidak mendapat izin dari otoritas setempat. Hal ini berakibat buruk untuk hutan dan juga lingkungan hidup: tanah longsor, banjir, dan juga kekurangan

oksigen.

CUTTING TREES NOT BAD

Cutting trees is NOT a bad thing. Trees are an

important resource for everyone on earth. The problem is when people

cut trees but do not replant them.

Trees are cut for many reasons. Industries based

on construction and making items such as

furniture (beds, tables) are- always in need of valuable

hardwood trees.

Lessons In Sustainable Land Development

CUTTING TREES NOT BAD

Wood (sometimes in the form of charcoal) is the major source of cooking fuel for over half of the

world (FAO 1999). Because populations and industries in every

country are growing, there is always a growing pressure on

forest resources.

Slash-and-burn agriculture, characterized by periodic burning of the land both to get rid of weeds and to use the ash as fertilizer, is also contributing to the rapid loss

of the world’s forests.Diunduh dari sumber:

Lessons In Sustainable Land DevelopmentCUTTING TREES NOT

BAD

Brush and forest fires not only inhibit the

regeneration of tree seedlings (though some

grasses, trees and shrubs have evolved the ability to

regenerate after fires), they also destroy what

little organic matter remains in the soil.

Fires are often caused by smoking and cigarettes,

unskilled beeking techniques, and

uncontrolled burning of fields for cultivation and

grazing.

Planting LocationA properly planted and maintained tree will grow faster and live longer.

Optimum planting time is early spring after the ground is thawed and before the tree begins to actively develop foliage. This is the time to plant bare root

trees.

OVERGRAZING IS BAD

Overgrazing is another major cause of land degradation. Communities all over the world rely on animals for

food, fiber, and labor.

Herding animals through grazing lands, if done

correctly, is a viable way to produce livestock, but it is

seldom done correctly. There are always too many animals in too little space, trampling the ground and eating all of

the vegetation, including tree seedlings.

Lahan Kritis merupakan lahan yang keadaan fisiknya demikian rupa sehingga lahan tersebut tidak dapat berfungsi secara baik sesuai dengan peruntukannya sebagai media produksi maupun

sebagai media tata air.

SOME TREES CAUSE LONG TERM DAMAGE

In the global program of Trees for the Future, we provide seeds of multi-purpose, fast-growing

(MPFG) trees.

In order to extend the program into many

climatic zones, and to make it more beneficial to the participants, we are constantly looking for

promising species, but we approach this with a great

of care when making recommendations.

SOME TREES CAUSE LONG TERM DAMAGE

Eucalyptus trees grow rapidly into true trees at a wide range of

elevations, soils, and climatic conditions.

They sustainably produce fuelwood and timber suitable for many local construction needs,

and they produce oil used in some medications and other

products,

But eucalyptus trees do not lend themselves to sustainable land

management systems

(Lisanework and Michelson, 1993).

Eucalyptus TreesPlantations are not meant to support a complex

ecosystem. A successful plantation species has to grow fast, have adequate wood properties and be resistant to disease when grown as a monoculture. The eucalyptus

can also become needy of room and produce extra vegetation and dominate areas where they are not

welcome. Eucalyptus trees and hybrids of eucalyptus usually have a high productivity.

SOME TREES CAUSE LONG TERM DAMAGE

Farmers quickly discovered that eucalyptus trees are causing problems with their roots by taking all available water and

nutrients from neighboring trees and crops, and also their leaves,

which blanket the ground, inhibiting new growth.

Eucalyptus trees inhibit the growth of other vegetation,

exposing soils to erosion, and causing lakes and ground water

to disappear with their aggressive roots.

. More than 4 billion Eucalyptus trees of over 150 species grow in the different climates of

Brazil.

SOME TREES CAUSE LONG TERM DAMAGE

Pine trees which are planted throughout much of the world for

their valuable timber present a similar problem. Beneath pine

trees, you will rarely find a productive understory; you tend to

find a blanket of acidic needles that inhibit the growth of

everything. The needles are also a great fuel

for forest fires.

Pine trees do have their benefits, but like eucalyptus trees, they do

not lend themselves to sustainable land management systems.

These trees can leave soils in much worse condition than when

they were planted.

Allelopathic Effects of Pinus halepensis Needles on Turfgrasses and Biosensor Plants

Panayiotis A. Nektarios, Garyfalia Economou and Christos AvgoulasHortScience February 2005 vol. 40 no. 1 246-250.

Fresh, senesced, and decaying pine needles from Pinus halepensis were evaluated for their allelopathic potential on

Festuca arundinacea, Cynodon dactylon and the biosensor plants Avena sativa and Lemna minor through in vivo and in vitro studies. The in vivo study was performed in growth chambers, using 6, 12,

and 18 g of pine needle tissue mixed with screened perlite as a substrate. The effects of the different pine needle types were

evaluated by determining the total root length, total root surface, root dry weight, total shoot length, total shoot surface, and shoot

dry weight. The in vitro study was performed in Petri dishes where seeds from each species were subjected to an increasing

concentration of pine needle extract. The extracts were obtained from pine needle ground tissue that was diluted with water and

either shacked at room temperature or placed in water bath at 40 °C for 24 h. The evaluation of the allelopathic potential was

performed with the determination of radicle length. The allelopathic potential of the pine needle tissues was confirmed

with bioassays using oat (A. sativa) and duckweed (L. minor). The results strongly suggested the allelopathic potential of the pine needle tissue, being more pronounced in the fresh, moderate in

the senesced, and low in the decaying pine needles. The allelopathic substances were species-specific, and the inhibition

resistance of the species tested followed the order F. arundinacea > C. dactylon > A. sativa. The inhibition of the L. minor suggested that the water soluble phytotoxic compounds were inhibitors of

Photosystem II.

SOME TREES CAUSE LONG TERM DAMAGE

In any program of Trees for the Future,

it encourage communities to plant multipurpose fast

growing trees that not only produce useful products

within a short time, but also encourage the growth of field crops, vegetables, and other

vegetation around them.

WATER AND SOIL

Chemical fertilizers and insecticides are unsustainable, temporary solutions that rarely improve the quality of the soil. Pesticides often kill many of the insects and microbes in soils

that are needed for natural processes.

There are, in fact, many beneficial insects that eat many of the pest insects, but most insecticides kill everything

indiscriminately.

Furthermore, insecticides get concentrated from smaller insects to the larger animals that eat them, ultimately poisoning the

entire food chain.

Alternatives to pesticide use entail (1) giving crops the strength they need to resist infestation by adding nutrients and organic matter to the soil, and (2) using Integrated Pest Management

techniques that ward off and kill insects.

WATER AND SOILFertilizers also cause long term damage, and are often

inadequate in their nutrient composition.

Soil need rich organic matter in the form of humus, compost, manure, etc.

Commercial fertilizers, often in the form of NPK pellets, contain just nitrogen, potassium, and phosphorus. These are three of the

major nutrients, but there are also plenty of other nutrients – such as manganese, iron, boron, zinc, and copper – that

chemical fertilizers tend not to contain.

Furthermore, rains can immediately leach these chemical fertilizers down through the soil, contaminating groundwater and

forcing farmers to apply more fertilizer every year.

SOIL AND FERTILIZER

Green manures are sustainable alternatives to chemical fertilizers.

Agricultural crops which received green manure of Gliricidia sepium (kakawate) yielded 9.5 tons per hectare of corn in

Oromia, Ethiopia.

A similar yield was obtained from plots which received green manure of ipil-ipil and Leucaena diversifalia, but a significantly ‘reduced yield was obtained from plots receiving recommended

levels of chemical fertilizer.

This implies that the use of multipurpose fast growing agroforestry species as a green manure can boost grain production over levels obtained from chemical fertilizer.

Additionally, the multipurpose species provide the farmer with fruit, fuelwood, fodder and construction wood.

The effects of potential land development on

agricultural land prices

We conduct a national-scale analysis of the determinants of agricultural land

values.

The empirical model of agricultural land prices is estimated with a cross-section

on approximately three thousand counties in the contiguous US.

The results provide evidence that option values associated with irreversible and

uncertain land development are capitalized into current farmland values.

For each county, we decompose the current agricultural land value into components measuring rents from

agricultural production and rents from future land development.

Agricultural Land Values and the Value of Rights to

Future Land Development

Effects of future land development on current agricultural land values. From a theoretical model of land

markets, we derive a reduced-form expression for agricultural land values

in terms of observable variables.

The estimated model, together with a spatial interpolation algorithm, is used

to generate a surface of estimated development rights values for Orange

County.

This approach overcomes several problems that arise with the use of

standard appraisal methods to value conservation easements.
