The special report on climate and
land that focuses on climate change, desertification, land degradation,
sustainable land management, food security and greenhouse gas fluxes in
terrestrial ecosystem has outlined the necessary prerequisite in the mitigation
and adaptation of climate change. This report is based on five standards;
v
SSPs(
desertification, land degradation and food security)
v World population.
v Income distribution
v Resource consumption
v
Land
use for year 2100
These reports show how the five
standards are linked together. That is, how increase or decrease in one of this
can affect the others.
DESERTIFICATION:
According to article 4.6,
desertification amplifies global warming through the release of CO2 linked with
the decrease in vegetation cover. Once vegetation cover is lost, soil is expose
to land degradation of different forms such as; soil erosion, rainfall,
flooding, drought frequency, severity in heat waves, dry land, wind, sea-rise
and permafrost thaw. That’s to say, the more vegetation cover we lost, the more
the adverse effects of climate change. From all indications, climate change
changes with nature (land).
LAND DEGRADATION:
Policies that
are outside the land and energy domains, such as on transport and environment,
can also make a critical difference to tackling climate change. An overall
focus on sustainability coupled with early action offers the best chances to
tackle climate change. From section 1.5, about a quarter of the earth’s
ice-free land area is subject to human-induced degradation. This corresponds
with section 2; since the pre-industrial period, the global average temperature
has raised nearly twice as much as the global average temperature. Soil erosion
from agricultural fields is estimated to be currently 10 to 20 times (no tillage)
to more than 100times (conventional tillage) higher than the soil formation
rate. Climate change driven land degradation are higher in pathways with a
higher population, increased land-use change, low adaptive capacity and other
barriers to adaptation. In section A 1.5, in dry lands, climate change and
desertification are projected to cause reductions in crop and livestock
productivity, modify the plant species mix and reduce biodiversity. Population
vulnerable to water stress, drought intensity and habitat degradation is
projected to reach 178million people by 2050 at 1.5oC warming, increasing to
220 million people at 2oC warming, and 277million people at 3oC warming; this
corresponds with section 5.7 that says changes in climate can amplify environmentally
induced migration both within countries and across borders. With an implication
in article 2.1 that projected increase in population and income combined with
change in consumption patterns, resulting in increased demand for food and
water in 2050 in all SSPs.
FOOD
SECURITY:
Many wonder what the world food
security will result to in the nearest future; are we going to bit Malthus
theory of population that says that, population is increasing at a geometric
progression and food is increasing at an arithmetic progression. In the report, about one third of food
produced is lost or wasted. Therefore, reducing inequalities improving incomes
and ensuring equitable access to food so that some regions are not disadvantage
are other ways to adapt to the negative effects of climate change. Increases in
production are linked to consumption change. In section 2.8, climate change has
already affected food security due to warming , changing precipitation patterns
and greater frequency of some crops(e.g maize, wheat) has declined, while in
many ever recent decades, climate change has resulted in lower animal growth
rates and production in pastoral systems in Africa. Another risk related to
food security was also outlined in article 6.4; risks related to food security
are greater in pathways with lower income increased food demand, increased food
prices resulting from competition for land, more limited trade and other
challenge to adaptation. There is robust evidence that agricultural pests and
diseases have already responded to climate change resulting in both increases
and decreases of infestations. Based on indigenous and local knowledge, climate
change is affecting food security in dry lands, particularly those in Africa,
and high mountain regions of Asia and South America.
SUSTAINABLE LAND MANAGEMENT PRACTICE
1.
Specific
agro-ecological conditions (practice relating to organic soils, peat lands and
weather and those linked to freshwater resources)
2.
Applying
immediate impacts which will include the conversion of high-carbon ecosystem
such as peat-lands, wetlands, range lands, mangroves and forests.
3.
Applying
multiple ecosystem services and functions but take more time to deliver include
afforestation and restoration as well as the restoration of high-carbon
ecosystem, agroforestry and the reclamation of degraded soil.
4.
Land
based options that deliver carbon sequestration in soil vegetation such as
afforestation; reforestation, agroforestry, soil carbon management on mineral
soils or carbon storage in harvest wood products do not continue to sequester
carbon indefinitely.
5.
Urban
green infrastructure that can reduce climate risks in cities as strategy for
reducing impacts.
6.
Policies
promoting the target of land degradation and mitigation such as customary
tenure, community mapping, redistribution, decentralization, co-management,
regulation of rental markets can provide both security and flexibility response
to climate change
7.
Mix
policy (can strongly reduce the vulnerability and exposure of human and natural
systems to climate change), than single policy approaches can deliver climate
change.
8.
Policies that improved access to markets for
inputs, outputs and financial services empowering women and indigenous peoples,
enhancing local and community collective action; reforming subsidies and
promoting an enabling trade system. Land restoration and rehabilitation efforts
can be more effective when policies support local management of natural
resource, while strengthening cooperation between actors and institutions,
including at the international land.
9.
The
effectiveness of decision-making and governance is enhanced by the involvement
of local stakeholders (particularly those most vulnerable to climate change
including indigenous people and local communities, women and the poor and marginalized
in the selection evaluation, implementation and monitoring of policy
instruments for land-based climate change adaptation and mitigation.
10.
Achieving
land degradation neutrality depends on the integration of multiple responses
across local, regional and national scales, multiple sectors including
agriculture, pasture, forest and water.
11.
Also,
sustainable land management practices require accounting for local
environmental and socio-economic conditions. Sustainable land management in the
context of climate change is typically advanced by involving all relevant
stakeholders in identifying land-use pressures and impacts as well as
preventing, reducing and restoring degraded land.
12.
Financial
transfers to women under the auspices of anti poverty program, spending on
health, education, training and capacity building for women, subsidized credit
and program dissemination through existing woman’s communication based
organization.
CONCLUSION:
CONCLUSION:
From these reports, many wonder if our land
is in a save, moderate or worse condition holding that the global emissions
were not mentioned in the predictions and policies from the reports. But, the bottom
line is that; actions are needed to prevent catastrophe in the nearest future
because our land is sensitive to climatic conditions.
